OBJECTIVE:To evaluate the effects of compound amino acids capsul es on hypoalbuminemia in patients with chronic renal failure undergoing hemodialysis.METHODS:30hemodialysis patients were selected to orally take2compound amino acids capsules(0.35g per capsule)twice daily for12weeks,renal and liver function and levels of serum albumin and pre-albumin were measured before and after the experiment.RESULTS:The levels of serum albumin and pre-albumin were increased significantly after the treatment,it were(30.5?4.6)g/L vs(35.9?7.1)g/L,and(213.0?46.9)mg/L vs(275.8?52.3)mg/L respectively(P

Psoriasis is a recrudescent chronic inflammatory dermatosis which is called“tinea”in ancient times. Its pathogenesis is not only associated with changes in the blood and body fluids, but also has close connection with external infection of six evil factors. This article sorted data of pathogenesis and treatment from the perspective of external infection of six evil factors, and discovered that pathogenesis of psoriasis includes external factors of four evils of wind, cold, damp and heat and internal factors of blood deficiency and blood dryness. Ancient treatment was based on dispelling wind, clearing away heat and moistening dryness. The pathogenesis can be summarized as follows:wind and poison attack skin and hinder blood production. The treatment can be “let in air for detoxification, enrich blood and moister dryness, cooling and activating blood”, blood and functional status of organs of patients should be observed, with a purpose to provide references and basis for modern clinical prevention and treatment of psoriasis.

Objective To investigate the effect of interferon alfα-2b on the ultrastructure and Caspase-3 levels in villus in early pregnancy with bacterial vaginal disease (BV). Method Early pregnant women were divided into two groups. The treated group included 25 early pregnant women with BV who chose to have an early termination and were treated with rhINFα-2b. The controling group included 30 early pregnant women without any genital tract infectious diseases. The caspase-3 levels in trophocytes were detected by immunochemistry and the ultrastructural changes were observed in villus by transmission electron microscopy. Result (1)There was no apparent difference of ultrastructural changes between the two groups. (2)There was no statistical significance of the levels of caspase-3 between the two groups (P>0.05). Conclusion The excessive apoptosis do not occur in the trophocytes when treated with INFα-2b.

AIM To determine the relationship between the elevation of endogenous inhibitor of nitric oxide synthase (NOS)N G,N G-asymmetric dimethylarginine (ADMA) and metabolic control in diabetic rats. METHODS Diabetes was induced in Sprague-Dawley rats by a single intraperitoneal injection of streptozotocin. At 72 h after injection, half of diabetic rats received insulin treatment for 8 weeks (20 U?kg -1?d -1,ih, bid). Serum levels of ADMA were measured by high-performance liquid chromatography. Thoracic aortic rings from non-diabetic age-matched control, untreated diabetic, and insulin-treated diabetic rats were tethered in isolated organ baths,contracted with 1 ?mol?L -1 phenylephrine, and challenged with either the endothelium-dependent vasodilator acetylcholine or the endothelium-independent vasodilator sodium nitroprusside. Serum concentrations of glucose, glycosylated serum protein, and malondialdehyde, derived from lipid peroxidation were also examined to estimate metabolic control.RESULTS Serum levels of ADMA significantly elevated in untreated diabetic rats compared with control rats. This elevation of ADMA was accompanied by impairment of relaxation response to acetylcholine but not sodium nitroprusside in aortic rings. Chronic insulin treatment not only prevented the elevation of serum ADMA, but also improved the impaired endothelium-dependent relaxation in diabetic rats. Serum levels of glucose, glycosylated serum protein, and malondialdehyde were significantly increased in parallel with the elevation of ADMA in untreated diabetic rats compared with control rats. These parameters were normalized after diabetic rats received insulin treatment. CONCLUSION These results provide the first evidence that the elevation of endogenous inhibitor of NOS in streptozotocin-induced diabetic rats is close related to metabolic control of the disease.

Objective To evaluate the effects of penehyclidine hydrochloride (PHC) on the expression of Toll like receptor-4 (TLR4) and nuclear factor kappa B (NF-κcB) in a rat model of sepsis-induced acute lung injury (ALI).Methods Seventy-two adult male Sprague-Dawley rats,weighing 180-220 g,were randomly divided into 3 groups (n =24 each) using a random number table:shame operation group (group S),ALI group and PHC group.Sepsis-induced ALl was induced by cecal ligation and puncture in anesthetized rats.In group PHC,PHC 0.45 mg/kg was intramuscularly injected immediately after cecal ligation and puncture.At 6,12,24 and 36 h after ligation,the broncho-alveolar lavage fluid (BALF) was collected for detection of TNF-α and IL-6 concentrations and the lungs were removed for determination of the expression of TLR4 (using RT-PCR and Western blot) and NF-κBp65 (using Western blot) in lung tissues and for microscopic examination.The pathological changes of lungs were scored.The wet to dry lung weight (W/D) ratio was calculated and the activity of myeloperoxidase (MPO) in lung tissues was measured.Results As compared with S group,the IL-6 concentrations in BALF at 6,12 and 24 h after ligation,TNF-α concentration in BALF at 6 and 12 h after ligation,and the expression of TLR4 and NF-κBp65,pathological scores,W/D ratio and MPO activity at each time point were significantly increased in ALI group (P ＜ 0.05).Compared with ALI group,the TNF-α concentration in BALF at 6 and 12 h after ligation,and IL-6 concentrations in BALF,the expression of TLR4 and NF-κBp65,pathological scores,W/D ratio and MPO activity at each time point were significantly decreased in group PHC (P ＜ 0.05).Conclusion PHC inhibits NF-κB activation and decreases inflammatory responses through blocking TLR4 expression in lung tissues,thus attenuating sepsis-induced ALI in rats.

Objective In order to understand the quality of drinking water sources and the environment of the Qinghai-Tibet Railway areas. Methods In 2002-2004, the first and second phase of the project of Qinghai-Tibet Railway, 37 sampling sites were chosen in the dry and rainy seasons and the water samples were analyzed according to the national standard test methods. Results In the first phase of the project, the eligible rates of the 39 test indexes of the water sources of 23 sampling sites in the Qinghai-Tibet Railway areas were 82%-95% in the dry season and some decreased in the rainy season. In the second phase, the eligible rates of the test indexes of the water sources of 14 sampling sites were 50%-100% in dry season and in the rainy season, the trend was the same as in the first phase. Conclusion Among the 37 water resources in the Qinghai-Tibet railway areas,the percent of gradeⅠ, gradeⅡ, grade Ⅲ and above grade Ⅲ water source was 67.57%,13.51%,2.70% and 16.22% respectively, some water sources can not be used as the drinking water sources due to the bad quality.

Objective To evaluate the safety of laparoscopic resection for giant abdominal benign mass.Methods Six cases of giant abdominal benign mass(8～25 in diameter)underwent laparoscopic exploration and resection under general anesthesia from July 2005 to March 2006.Results The laparoscopic resection was accomplished in all the 6 cases.The operation time was 75～220 min(mean,135 min),the intraoperative hemorrhage volume was 20～100 ml(mean,55 ml),the duration for abdominal drainage was 1～3 d(mean,2 d),and the postoperative hospital stay,2～7 d(mean,4.3 d).There was no complications such as intestinal injury,postoperative bleeding,or abdominal infection.Follow-up visits for 1～9 months(mean,6.5 months)found no recurrence.Conclusions Laparoscopic resection of giant abdominal benign mass is a feasible and safe minimally invasive technique.
