何嘉琳治疗卵巢早衰的临床经验

吾师何嘉琳，幼承庭训，从事妇科多年，学验颇丰，吾有幸侍诊左右，深感何师对卵巢早衰诊治经验独到，现作一介绍，以飨同道。 中医学无卵巢早衰病名，其临床表现散见于脏躁、闭经、不孕等病证中。何师认为，其病总以肾虚为本，兼及心肝脾三脏失调，病位在冲任胞宫，变化在气血，表现为经水渐断。     

Clusterin expression in cutaneous CD30-positive lymphoproliferative disorders and their histologic simulants

Background:  Clusterin is a ubiquitous 80 kDa heterodimeric glycoprotein previously shown to be expressed on tumor cells of systemic and, to a lesser extent, primary cutaneous anaplastic large cell lymphoma (PC-ALCL). Lymphomatoid papulosis (LyP), an important differential diagnosis of ALCL, has been studied for clusterin expression in only a small number of cases. The aim of this study was to compare clusterin immunostaining patterns in LyP and other cutaneous histologic simulants with those of PC-ALCL.
Methods:  Formalin-fixed, paraffin-embedded sections of PC-ALCL (6), LyP (20), mycosis fungoides with large cell transformation (MF-LCT, 12), pityriasis lichenoides et varioliformis acuta (PLEVA, 12), arthropod bite reaction (ABR, 12) and lymphomatoid reactions (LR, 9) were immunostained for clusterin and evaluated for staining pattern and distribution. All diagnoses were made with clinicopathologic correlation.
Results:  Characteristic dot-like Golgi staining was identified in 10/20 LyP (50%), 4/6 PC-ALCL (67%) and 9/12 MF-LCT (75%). Two of 12 PLEVA (17%), 1 of 12 ABR (8%) and 2 of 8 LR (25%) had lymphocytes (< 25%) with diffuse cytoplasmic staining. Dermal dendritic cells stained strongly for clusterin. High background staining occurred in some cases.
Conclusion:  Clusterin immunostaining does not reliably distinguish between LyP, PC-ALCL or MF-LCT, but could distinguish LyP from its reactive histologic simulants.

Recurrent acalculous cholecystitis and sclerosing cholangitis in a patient with X-linked hyper-immunoglobulin M syndrome.

X-linked hyper-immunoglobulin M (IgM) syndrome (XHIGM) is a rare genetic primary immunodeficiency disease caused by mutations of the CD40 ligand (CD40L) gene with normal or elevated levels of IgM and markedly decreased serum IgG, IgA, and IgE. Liver disease may occur as a clinical manifestation in XHIGM. This complication appears to increase with age. We report an 18-year-old male patient who had recurrent episodes of acalculous cholecystitis (AC) and sclerosing cholangitis (SC). The diagnosis of XHIGM was confirmed by the finding of CD40L expression < 1% of normal and a tyrosine 169 asparaginase (t526a) mutation in exon 5 (the tumor necrosis factor domain) of the CD40L gene. The patient had direct hyperbilirubinemia (direct bilirubin 5.5 mg/dL, total bilirubin 8.7 mg/dL), cholestasis (alkaline phosphatase 1133 U/L, gamma-glutamyl transferase 1019 U/L) and elevated transaminases (aspartate aminotransferase 70 U/L, alanine aminotransferase 101 U/L). Findings on abdominal ultrasound and abdominal computed tomography were compatible with AC. After the fourth episode of cholecystitis, cholecystectomy and liver biopsy were performed. Operative cholangiography revealed poor opacification of the hepatic duct and proximal common bile duct; the upstream intrahepatic bile ducts were not visualized. The biopsy specimen showed marked fibrosis of the portal areas. Enterococcus species was cultured from the bile. Children or adolescents with recurrent AC and SC should be evaluated for an underlying immunodeficiency syndrome such as XHIGM.     

Elimination of malignant clonogenic cells from human bone marrow using multiple myeloid cell-specific monoclonal antibodies and complement.

Single or combined monoclonal antibodies (McAbs) Zh53, Zh820, and Zh2-1 have been used to eliminate malignant clonogenic cells from human bone marrow. The test of cytotoxicity showed that all of these McAbs could express high specific cytotoxic action against HL-60 cells and were selectively complement-dependent cytotoxic to various types of fresh leukemic cells. Clonogenic assay detected that single treatment with antibody and rabbit complement (RC) could reduce clonogenic units of HL-60 cells by more than 2 logs and two treatments reduced clonogenic units by more than 4 logs. However, combination of 2 McAbs could reduce clonogenic units by 4-5 logs. The data suggest that multiple treatments with McAbs and RC or a combination of 2 McAbs are more effective than a single treatment in eliminating clonogenic tumor cells. Treatment of normal human bone marrow with Zh53, Zh2-1 and RC did not produce a loss of normal CFU-GM, but treatment with Zh820 reduced the clonic units of normal CFU-GM by 24%.

     

灯盏花素注射液对大鼠脑缺血-再灌注脑损害的凋亡抑制作用

目的:研究灯盏花素(Bre)对大鼠脑缺血-再灌注引起脑损伤的保护作用。方法:实验选用40只雄性Wistar大鼠,大鼠被随机分成5组:假手术组、对照组、硫酸镁(Mg-SO4)治疗组、灯盏花素治疗和组。自大鼠颈总动脉插入尼龙线栓栓塞大脑中动脉,造成大脑缺血,拔出线栓实现再灌注。脑缺血10min后给予75mg/kg和50mg/kgBre及30mg/kgMgSO4,分别于脑缺血1h,再灌注2h,5h和23h分别进行神经病学评分,并于脑缺血1h,再灌注23h时测定脑梗死面积,用TUNEL法和免疫组化法分别检测脑组织凋亡细胞和Caspase-3阳性细胞的变化。结果:灯盏花素降低脑缺血-再灌注大鼠神经病学评分,缩小脑梗死面积,降低脑组织凋亡细胞和Caspase-3阳性细胞数量,其作用强于硫酸镁。结论:灯盏花素通过抑制细胞凋亡可显著保护大脑缺血-再灌注引起的脑损伤,其作用优于单用硫酸镁。     

Association of the Platelet Glycoprotein Ⅰa C807T Gene Polymorphism With Risk of Myocardial Infarction in Chinese

Objectives To investigate the relationship of the GPIa C807T dimorphism to the risk of myocardial infarction (MI) in Chinese. Methods We did a case-control study including 100 patients and 110 controls with same race. An allele-specific polymerase chain reaction (PCR) was used for genotyping of C807T polymorphism. Results An apparent association was found between the T807 allele and MI among individuals younger than the mean age of 60 years (odds ratio,2.49; 95% confidence interval, 1.08 ～ 6.22 ). The T807 allele remained an independent risk factor for MI when age, sex, smoking, hypertension, diabetes, bodymass index, LDL-cholesterol and HDL-cholesterol were adjusted by logistic regression. Conclusions GPⅠa T807 appears to be an independent risk factor for MI.     

Neurochemical studies on the mesolimbic circuitry of antinociception

Previous studies using the technique of microinjection into brain nuclei indicated that the periaqueductal gray (PAG), nucleus accumbens, habenula and amygdala play an essential role in pain modulation and that these nuclei possibly act through a ‘mesolimbic neural loop‘ to exert an analgesic effect, in which Met-enkephalin (MEK) and β-endorphin (β-EP) have been implicated as the two major opioid peptides involved in antinociception. In the present study performed in rabbits, intracranial microinjection was supplemented with push-pull perfusion and radioimmunoassay to determine whether the release of enkephalins (ENK) and β-EP was increased in these nuclei when the putative neural circuit was activated by morphine administered into one of the nuclei. The results showed: (1) microinjection of morphine into the PAG increased the release of ENK and β-EP in the N. accumbens, and vice versa; (2) microinjection of morphine into the N. accumbens increased the release of ENK and β-EP in the amygdala, and vice versa; (3) morphine microinjected into the PAG caused an increase in the release of ENK and β-EP in the amygdala and vice versa, although the release of ENK in PAG was statistically not significant. These results indicate that PAG, N. accumbens and amygdala are connected in a network served by a positive feedback circuitry.     

利福喷汀治疗耐利福平肺结核的疗效分析

目的分析增加利福喷汀的用药剂量对利福平耐药肺结核的疗效，以评价利福喷汀在治疗利福平耐药患者中的作用。方法根据药敏结果选取耐利福平肺结核患者101例，分为治疗1组（利福平低耐），治疗2组（利福平高耐），两组治疗方案中均含利福喷汀，对照组（利福平高耐）治疗方案中不合利福喷汀。观察治疗后3、18个月疗效。结果治疗1组在各阶段的痰菌阴转率、病灶吸收和空洞闭和情况明显优于治疗2组和对照组，两组差异有统计学意义；治疗2组的痰菌阴转率、病灶吸收和空洞闭和情况略优于对照组，两者差异无统计学意义。结论对利福平耐药的患者尤其在利福平低度耐药病例中，可以选择增加利福喷汀用药剂量的方案进行治疗，在利福平高度耐药病例中利福喷汀的作用不能确定。
