Objective In order to provide important theoretical basis for further improving design of DC-7/7A high altitude partial pressure suit and FTF-2 air ventilation suit (named as A suit and B suit), the performance of ventilating heat dissipation of DC-7/7A and FTF-2 was studied. Methods Five healthy volunteers were enrolled to took participate in A group and B group tests. Environmental weather conditions for A and B suits were set at Tdb 40℃ and 45℃,rh 45% and 40% respectively, and the test time was 90min and 120 min respectively. Results During the test for A group and B group, Ts ranged from 31.5℃ to 34.5℃ for human comfort. Average skin temperatures of the lower part of the body were from 33.1℃ to 33.8℃. Skin temperatures of the legs did not obviously change or slightly lowered. Heart rate showed an increase of 12 beats/min and 14 beats/min. Sweat quantities were measured to be 0.288?0.056kg/1.5h and 0.445kg?0.077 kg/2h respectively. Evaporation rates were 77.4?3.6% and 84.2?2.4% respectively. Subjective uncomfortable sensation was more obvious as test time went on. Conclusion The results of the ventilating heat dissipation for both groups were quite good, but the findings suggested that the number of the ventilating holes for some important sites should shall be re-considered. Pilots wearing A group and B group with ventilation function would still suffer from mild heat stress and obvious subjective discomfort in hot enviroment.

Diabetic gastroparesis (DGP) is one of the most common complications of diabetes. Acupuncture is an ef-fective treatment for DGP in recent years. Literatures on acupuncture therapy for DGP treatment were screened for the past 10 years. Statistical analysis was made on acupoints used in the literatures in order to find the most com-monly used acupoints and combinations. This article was aimed to explore and summarize the use of the acupuncture law for the better service of clinical practice.

In this study, the human umbilical vein endothelial cell model was used to study the regulating effect of lipophilic components in Salvia miltiorrhiza on angiogenesis, and explore its possible mechanism. The cell model was established to determine the effect of lipophilic components in S. miltiorrhiza on the proliferative activity and migration capacity of endothelial cells. Then the realtime fluorescence quantification PCR technology was applied to detect the changes in the gene expressions of angiogenesis-related cytokines VEGF-A, VEGF-C and MMP-9. The results showed that 5 mg x L(-1) lipophilic components in S. miltiorrhiza could inhibit the proliferation and migration of endothelial cells, and reduce the expression of VEGF-A and MMP-9 genes. It indicated that lipophilic components in S. miltiorrhiza may inhibit the proliferation and migration of endothelial cells by inhibiting the expression of VEGF-A and MMP-9 genes, so as to show the inhibitory effect on angiogenesis.

Objective To summarize the management of scrotal gangrene.Methods Totally,14 male patients (mean age,48 years;age range,27-74 years) with scrotal gangrene were treated from August 2003 to June 2005.Among these patients,scrotal gangrene was complicated by perianal and penile gangrene in 2 cases;by perianal,penile and inguinal gangrene in 10 cases;by perianal,penile,inguinal gangrene and abdominal subcutaneous gangrene in 2 cases.Three cases had concomitantly necrosis of the penis;and 5 ca- ses,orchitis.Bacterial cultures were performed in all 14 cases with the positive results.All patients underwent surgical treatment,including PhaseⅠincisions,aggressive debridement,drainage,irrigation,and scrotoplas- ty.After operation they received antibiotic therapy and supporting treatment.Three cases of penile necrosis underwent complete penis amputation and transplanting the urethra before the anus.Five cases of orchitis un- derwent unilateral orchiectomy.Two cases of abdominal gangrene underwent surgical subcutaneous treatment, including incision,aggressive debridement,drainage,and irrigation.Results Twelve cases undergoing scrotoplasty achieved PhaseⅠhealing.Two cases undergoing urethral fistulation recovered well.Ten cases of penile skin gangrene received penile dermatoplasty 1 month later,and then recovered.Two cases who had al- ready had AIDS died 2 or 3 d after operation.Conclusions The management of scrotal gangrene primarily consists of early and aggressive debridement,antibiotic therapy and supporting treatment.The PhaseⅠde- bridement and scrotoplasty as well as drainage are effective for the treatment of scrotal gangrene.

Objective To screen serum proteomic marker of hepatic echinococcosis, establish a diagnotic model of serum protein fingerprint patterns, and evaluate its clinical application for hepatic echinococcosis. Methods Serum samples from 68 patients with hepatic echinococcosis matched with 73 controls composed of 33 patients with liver diseases other than hepatic echinococcosis and 40 healthy people were collected. All subjects were divided into training group (37) and testing group (67). Serum protein profiling of patients with hepatic echinococcosis and controls were detected using surface enhanced laser desorption/ionization time of flight mass spectrometry(SELDI-TOF-MS) and weak cation exchange protein chip(WCX2). Peak intensities were compared, in the training group, between 37 patients with hepatic echinococcosis and 37 controls, 5 patients with HCE and 5 patients with HAE, and 8 patients with hepatic echinococcosis before and after operation, respectively. ZJU-Protein Chip Data Analyze System(ZJU-PDAS) was used for data analysis and the model of serum protein fingerprint patterns was build by support vector machine (SVM). The sensitivity and specificity of the model for diagnosis of hepatic echinococcosis were verified by blind method on samples of testing group. Results There were nine different protein peak spectra between hepatic echinococcosis group and control group, of which eight protein peak spectra decreased in patient group, their relative molecular mass were 1044, 1047, 1073, 1075, 1338, 6453, 6649, 8714 m/z, respectively, while one protein peak spectrum(5651 m/z) increased(P < 0.05). The sensitivity,specificity, positive predictive and negative predictive value of the model validated by blind method were 77.4% (24/31), 66.7% (24/36), respectively. There were two different protein peak spectra between HCE group and HAE group, Their relative molecule mass were 8716 and 2751 m/z, respectively (P < 0.05). Six different proteins were detected from pre-operation group and post-operation group. Their relative molecular mass were 1297, 1505, 1525, 1534, 5921, 5941 m/z, respectively(P < 0.05). Conclusions It is a successful way to screen serum proteomic marker in patients with hepatic echinococcosis by SELDI-TOF-MS and Bio-informatics, and the marker has a potential clinical value in diagnosis and judging prognosis of hepatic echinococcosis.
