Bloodletting Puncture at Hand Twelve Jing-Well Points Relieves Brain Edema after Severe Traumatic Brain Injury in Rats via Inhibiting MAPK Signaling Pathway

Objective:To investigate whether blood-brain barrier(BBB)served a key role in the edema-relief effect of bloodletting puncture at hand twelve Jing-well points(HTWP)in traumatic brain injury(TBI)and the potential molecular signaling pathways.Methods:Adult male Sprague-Dawley rats were assigned to the shamoperated(sham),TBI,and bloodletting puncture(bloodletting)groups(n=24 per group)using a randomized number table.The TBI model rats were induced by cortical contusion and then bloodletting puncture were performed at HTWP twice a day for 2 days.The neurological function and cerebral edema were evaluated by modified neurological severity score(mNSS),cerebral water content,magnetic resonance imaging and hematoxylin and eosin staining.Cerebral blood flow was measured by laser speckles.The protein levels of aquaporin 4(AQP4),matrix metalloproteinases 9(MMP9)and mitogen-activated protein kinase pathway(MAPK)signaling were detected by immunofluorescence staining and Western blot.Results:Compared with TBI group,bloodletting puncture improved neurological function at 24 and 48 h,alleviated cerebral edema at 48 h,and reduced the permeability of BBB induced by TBI(all P<0.05).The AQP4 and MMP9 which would disrupt the integrity of BBB were downregulated by bloodletting puncture(P<0.05 or P<0.01).In addition,the extracellular signal-regulated kinase(ERK)and p38 signaling pathways were inhibited by bloodletting puncture(P<0.05).Conclusions:Bloodletting puncture at HTWP might play a significant role in protecting BBB through regulating the expressions of MMP9 and AQP4 as well as corresponding regulatory upstream ERK and p38 signaling pathways.Therefore,bloodletting puncture at HTWP may be a promising therapeutic strategy for TBI-induced cerebral edema.

昆虫抗冻蛋白及其在医学领域中的应用

抗冻蛋白(antifreeze protein,AFP)是一类结构多样的蛋白质,具有热滞效应(thermal hysteresis,TH,降低冰点而不改变熔点)和重结晶抑制效应(recrystalization inhabition,RI).通过非共价吸附抑制机制吸附到冰核表面,限制冰晶生长和抑制冰晶重结晶,从而保护有机体免受结冰引起的伤害.由于抗冻蛋白具有阻止冰晶生长而不破坏细胞的特点,因而利用抗冻蛋白在低温中长期保存各种细胞、组织和器官,特别在器官移植中可能具有很好的应用前景.     

Sternal Reconstruction of Deep Sternal Wound Infections Following Median Sternotomy by Single-stage Muscle Flaps Transposition

Objective To assess clinical effectiveness of using bilateral pectoralis major or plus rectus abdominis muscle flaps in treating deep sternal wound infection （DSWI） following median sternotomy. Methods Between January 2009 and December 2013, 19 patients with DSWI after median sternotomy for cardiac surgery were admitted to our hospital, including 14 males （73.7%） and 5 females （26.3%）, aged 55±13 （18-78） years. According to the Pairolero classification of infected median sternotomies, 3 （15.8%） patients were type II, and the other 16 （84.2%） were type III. Surgical procedure consisted of adequate debridement of infected sternum, costal cartilage, granulation, steel wires, suture residues and other foreign substances. Sternal reconstruction used the bilateral pectoralis major or plus rectus abdominis muscle flaps to obliterate dead space. The drainage tubes were placed and connected to a negative pressure generator for adequate drainage. Results There were no intraoperative deaths. In 15 patients （78.9%）, bilateral pectoral muscle flaps were mobilized sufficiently to cover and stabilize the defect created by wound debridement. 4 patients （21.0%） needed bilateral pectoral muscle flaps plus rectus abdominis muscle flaps because their pectoralis major muscle flaps could not reach the lowest portion of the wound. 2 patients （10.5%） presented with subcutaneous infection, and 3 patients （15.8%） had hematoma. They recovered following local debridement and medication. 17 patients （89.5%） were examined at follow-up 12 months later, all healed and having stable sternum. No patients showed infection recurrence during the follow-up period over 12 months. Conclusion DSWI following median sternotomy may be effectively managed with adequate debridement of infected tissues and reconstruction with bilateral pectoralis major muscle or plus rectus abdominis muscle flap transposition.

Acupuncture Treatment of Vomiting

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.

Analysis of CK-19,PDX-1,Nestin,Ngn3 in different donor islet purity in rats

Objective: To investigate if there are the CK-19, PDX-1, Nestin, Ngn3 positive cells in the donor islets of different purity in rats. Methods: Thirty male adult SD rats were randomly divided into 3 groups. Islets were isolated using digestion by ductal injection of collagenase. Group Ⅰ (n=10): Separating cell preparations were not purified, Group Ⅱ(n=10): Islet sediment was purified with 25% Ficoll400 ,Group Ⅲ (n=10): Islet sediment was purified with 25% and 11% Ficoll-400. The levels of protein of CK-19, PDX-1, Nestin and Ngn3 were detected by immunohistochemistry and the mRNA of CK-19, PDX-1, Nestin, Ngn3 was amplified by RT-PCR. Results: After two different purification methods applied, three islet preparations of different purities were obtained. The difference of islet purity was significant among various groups (P＜0.05). Compared with group Ⅱ and group Ⅲ,the protein and mRNA of CK-19, PDX-1, Nestin,Ngn3 were both higher in group Ⅰ; group Ⅲ was poorly expressed. Conclusions: The three different islet purity donor islet have different CK-19, PDX-1, Nestin, Ngn3 positive cells within them, indicating that there are some islet stem cells in the purified donor islet.     

A preliminary screening study on the associated proteins in human psoriasis vulgaris by serum proteomics technologies

Objective：To investigate the optimum screening conditions of associated proteins in human psoriasis vulgaris by serum proteomics technique, and to screen the different expression proteins related with psoriasis vulgaris. Methods：Serum samples of peripheral blood were collected from newly diagnosed psoriasis vulgaris patients in the clinic, and 20 matched healthy persons. Serum albumin IgG was removed by filtering with ProteoExtract Albumin/IgG. After comparative proteomics analysis the different protein spots were identified using 2-DE and MS. Results ：Electrophoresis figures with high resolution and reproducibility were obtained. Three different expression proteins were found only in the serum from psoriasis vulgaris patients, while nine other different proteins expressing from healthy volunteers. Conclusion：The protein expression was different in the serum between the psoriasis vulgaris patients and healthy volunteers. It was hoped that we could find the biomarkers related to psoriasis vulgaris by using proteomics.
