Hereditary characteristics of enzyme deficiency and dermatoglyphics in congenital color blindness

The hereditary characteristics of enzyme deficiency and dermatoglyphics in congenital color blindness (CCB) were studied. We propose that there is a linkage between the two loci on the X-chromosome determining CCB and glucose-6-phosphate dehydrogenase (G6PD), based on our study of a high incidence of G6PD deficiency in 156 male cases with CCB. The CCB gene is closely linked with that of G6PD deficiency from our pedigree investigations. The rise in the frequency of eight or more whorls, the low value of atd angle and the presenting rate of real palmar patterns of the thenar, hypothenar and I, areas presented the hereditary traits of congenital color blindness.     

Calculation of cyclic voltammetric responses for the catalytic reduction of substrates via intramolecular electron transfer within a catalyst-substrate complex formed on electrode surfaces

Cyclic voltammetric responses are calculated for the case where the reduction of a substrate proceeds only via intramolecular electron transfer to the substrate molecule when it is bound to reduced catalyst molecules present in a single monolayer on the electrode surface. The dependences of the voltammetric responses on the equilibrium constant for the formation of the catalyst-substrate complex, the rate of its formation and the rate of intramolecular electron transfer are discussed. Procedures are described for estimating the rate constant for the intramolecular electron transfer reaction and for discriminating between mechanistic possibilities.     

Influence of Qingdai Compound Capsule on the expression of c-myc in psoriatic keratinocytes) on the expression of c-myc in psoriatic keratinocytes

In this immunohistochemical study, the authors detected the expression of c-myc in keratinocytes (ECK) from 30 psoriatics before and after Qingdai Compound Capsule (QDCC) treatment and 12 normal subjects for control. The results showed that the ECK of patients before treatment was significantly higher than that in the normal control group, and its level was correlated with histopathological changes of affected skin. After treatment the ECK was normalized. It is believed that QDCC could decrease the ECK in psoriatics and this effect was probably mediated by inhibiting c-myc expression. This study provided an experimental evidence for the application of QDCC in treating psoriasis.     

改良超滤对婴幼儿心脏手术输血的影响

目的　观察改良超滤技术在婴幼儿体外循环心血管手术中对输血及术后出血的影响。方法　 6 0例接受体外循环下心血管手术的先天性心脏病患儿 ,均分为对照组 (不接受任何超滤 )、常规超滤组 (CUF组 )和改良超滤组 (MUF组 )。观察术中库血用量、血浆用量、血球压积的变化及术后2 4h出血量 ,并用SSPS/PC进行统计学处理。结果　MUF组库血用量、血浆用量、术后 2 4h出血量显著低于对照组和CUF组 (P <0 0 1) ,且滤出水量明显多于CUF组 (P <0 0 1)。结论　在婴幼儿心血管手术中 ,改良超滤可有效排出体内水分 ,提高血球压积 ,明显减少输血及术后出血 ,是节约用血的重要手段之一。

Prevalence of knee abnormalities in patients with osteoarthritis and anterior cruciate ligament injury identified with peripheral magnetic resonance imaging: a pilot study.

OBJECTIVES: 1) To assess, with a peripheral magnetic resonance imaging system (pMRI), the prevalence of bony and soft tissue abnormalities in the knee joints of normal subjects, osteoarthritis (OA) patients, and individuals who have suffered an anterior cruciate ligament (ACL) rupture; and 2) to compare the prevalence among groups. METHODS: Magnetic resonance (MR) images of 28 healthy, 32 OA, and 26 ACL damaged knees were acquired with a 1.0-T pMRI system. Two radiologists graded the presence and severity of 9 MR image features: cartilage degeneration, osteophytes, subchondral cyst, bone marrow edema, meniscal abnormality, ligament integrity, loose bodies, popliteal cysts, and joint effusion. RESULTS: Ten of 28 healthy (35.7%), 24 of 26 ACL (92.3%), and all OA knees (100%) showed prevalent cartilage defects; 5 healthy (17.9%), 20 ACL (76.9%), and all OA knees (100%) had osteophytes; and 9 normal (32.1%), 21 ACL (80.8%), and 29 OA knees (90.6%) had meniscal abnormalities. One-half of the knees in the OA group (16 of 32, 50%) had subchondral cysts, and almost one-half had bone marrow edema (15 of 32, 46.9%). These features were not common in the ACL group (7.7%, and 11.5%, respectively) and were not observed in healthy knees. The OA group had the most severe cartilage defects, osteophytes, bone marrow edema, subchondral cysts, and meniscal abnormalities; the ACL group showed more severe cartilage defects, osteophytes, and meniscal abnormalities than did normal subjects. CONCLUSION: The results suggest that knees that have sustained ACL damage have OA-like reatures; most subjects (19 of 26, 73.1%) could be identified as in the early stage of OA. The prominent abnormalities present in ACL-damaged knees are cartilage defects, osteophytes, and meniscal abnormalities.     

王霞芳治疗小儿泄泻的经验

小儿泄泻的病因病机因其自身稚阴稚阳的生理特点而较成人为多发,泄泻久甚,易耗伤气液,甚至出现伤阴伤阳的重证、变证。故要重视及时正确地治疗,以防产生危候。王霞芳老师治疗小儿泄泻首先注重审证求因,在精确辨证基础上立法选方而施治,并在病变过程中法随症变,灵活化裁,刻刻护卫脾气胃津,斡旋脾胃气机,重视清浊升降枢机作用。尝用葛根、扁豆衣、荷叶等轻灵升清之品,宣发清阳,泄泻自和。对屡治不愈、迁延日久者,王师认为应辨证细致,选药精到,且又及时而适当地参入止涩药物。固肠止涩法之运用,必须具备苔净,腹软,溲通,无表证和里积等条件,方为合宜。
