Objective To investigate the effect of underwater treadmill training (UWTT) on patients with hemiplegia after stroke. Methods Based on routine rehabilitation, 15 hemiplegic patients after stroke were treated with UWTT system 20 min/d, 5 times a week for 4 weeks. Walking distance and speed in water were tested before and after UWTT. Dynamic balance function and static balance function were also assessed by Active Balancer assessment. Results All the items improved significantly after treatment (P<0.01), except deflection center displacement of X and Y axis (P>0.05). Conclusion UWTT can improve the walking ability and balance function of hemiplegic patients after stroke.

Objective To provide the oxygen supply apparatus when the civil aviator and airforce pilot are inspected the hypoxia tolerance and altitude tolerance in the hypobaric environment.Methods Demand oxygen and contstant flow oxygen were supplied.Results The portable hypobaric oxygen supply apparatus can supply mixed oxygen below the altitude 8 000 m,and the oxygenous concentration of mixed oxygen was adjusted according to the altitude.The pure oxygen was supplied when the altitude was at 8 000～12 000 m.Conclusion The normal and emergency oxygen supply performance can fulfill the system physiological requirements.The portable hypobaric oxygen supply apparatus may be used by the persons engaging in special task on plateau also.

AIMSome surfactants such as DSPE-PEG, Tween 80 and Brij 35 were used to modify the amphotericin B liposome, improve the stability, optimize the tissue distribution and decrease the toxicity of amphotericin B liposome.

METHODSThe amphotericin B liposome was prepared by the film-supersound method. The effects of cholesterol and amphotericin B on the encapsulation percentage were studied. The diameter, leakage percentage in phosphate buffer solution(PBS) and calf blood serum, and tissue distributions of amphotericin B liposome in the rat were determined.

RESULTSThe top encapsulation percentage of amphotericin B liposome is (91.2 +/- 1.6)%. After modification with DSPE-PEG, Tween 80 and Brij 35, the encapsulation percentages were improved, the average diameters were decreased and the stabilities were improved, the amphotericin B concentrations in the liver, spleen and kidney were decreased, and the amphotericin B concentrations in the brain were increased, especially in the AmB-L-Tween 80 group.

CONCLUSIONDSPE-PEG and Brij 35 could decrease the clearing of reticuroendothelial systems(RES) to the amphotericin B liposome and Tween 80 could facilitate the transporting of amphotericin B liposome into the brain.

OBJECTIVETo explore the therapeutic efficacy of patients with ulcerative colitis (UC) treated by retention enema and per-colonoscopic spraying of Zhikang Compound Liquid (ZKCL).

METHODSEighty-six patients with UC were divided into two groups. The 52 patients in the treated group were treated for 4 courses of retention enema, the drug for enema used in the 1st course was ZKCL-A (consisted of normal saline, Zhikang capsule, gentamycin and dexamethasone) and smecta, in the 2nd course ZKCL-A alone, in the 3rd and 4th course, ZKCL-B (with the same contents of ZKCL-A but without dexamethasone), the enema was carried out once a day in the evening, 15 days as one course. Besides, local spraying of ZKCL-A and smecta were given once by colonoscopy before the 1st and 3rd course. The 34 patients in the control group were treated by salicylazosulfapyridine orally.

RESULTSIn the treated group, 32 patients got complete remitted, 15 were treated effectively, 5 ineffectively, the total effective rate being 90.38% while the corresponding number in the control group were 8, 14, 12, and 64.71%, respectively. Significant difference was seen when compared with the therapeutic effects of the two groups. CONCLUSION Good efficacy was got in treating patients with UC by retention enema and per-colonoscopic spraying with ZKCL.

OBJECTIVETo investigate the changes in the plasma levels of endotoxin in severe burn patients during administration of antibiotics.

METHODSFifty severe burn patients with burn area larger than 30% TBSA were enrolled in the study, and they were respectively treated with Netilmicin (A group), Cefoperazone (B group), Ceftazidime (C group) and Imipenem/Cilastatin (D group). Venous blood samples were harvested for determination of endotoxins levels before treatment and 1, 2, 3, 5, 7 post-treatment day (PTD).

RESULTSThe plasma levels of endotoxin were elevated in different degrees in A, B and C groups. The plasma levels of endotoxin in B group were higher on 1, 2 PTD than on 3, 5, 7 PTD, and they were also higher than that in D group (P < 0.05). The plasma levels of endotoxin in C group reached the peak on 5 PTD [(0.398 +/- 0.172) EU/mL], which were higher than that before treatment [(0.251 +/- 0.142) EU/mL, P < 0.05] and other groups (P < 0.05). The plasma levels of endotoxin in D group were lower on 1, 2 PTD than that before treatment (P < 0.05).

CONCLUSIONDifferent amounts of endotoxins can be released after treatment with antibiotics in severe burn patients. Attention should be paid to the effect of antibiotics on the levels of endotoxin in practice.

OBJECTIVETo study the risk factors of hepatitis B virus (HBV) intrauterine infection.

METHODSRisk factors of HBV intrauterine infection were analyzed by nested case control study.

RESULTSData from univariate analysis revealed that risk factors of HBV intrauterine infection were positive results on HLA-DR3 (OR = 4.71, 1.62-13.66), HBV DNA (OR = 6.59, 2.72-15.97) and HBeAg (OR = 4.53, 1.93-10.64) in pregnant women, HLA-DR3 (OR = 3.91, 1.18-12.94) in newborn, HLA-I) R3 (OR = 5.96, 1.14-31.15) both in pregnant women and her newborns and HBV infection in placentas (OR = 2.51,1.12-5.60). Results from Multivariate unconditional logistics regression analysis showed that the risk factors of HBV intrauterine infection were positive in both HLA-DR3 (OR = 4.65, 1.44-15.05) and HBV DNA (OR = 6.56, 2.65-16.23) in pregnant women. However, there was no interaction between the two factors. The exposure rate of other factors did not reveal the difference in the two groups. With the increase of HBV DNA in pregnant women, the risk of HBV intrauterine infection was rising (chi2 = 16.74, P < 0.05).

CONCLUSIONRisk factors of HBV intrauterine infection were HLA-DR3 positive and HBV DNA positive in pregnant women but there was no interaction between the two factors. The risk of HBV intrauterine infection was increased along with the increase of HBV DNA in pregnant women.

OBJECTIVETo study the differentially expressed genes in asthenospermia to gain a deeper insight into the molecular mechanisms of the disease.

METHODSWe analyzed the differentially expressed genes in asthenospermia using GATHER, PANTHER and ToppGene online bioinformatics tools.

RESULTSOur bioinformatics mining and analyses revealed that the differentially expressed genes in asthenospermia played important roles in the cellular protein and macromolecular metabolism, protein modification, cell death, cell apoptosis and apoptosis induction.

CONCLUSIONAsthenospermia patients experience a decline in sperm activity and the basic life activities of sperm simultaneously, and are also prone to cell apoptosis or death. Such differentially expressed genes as KIF3B, MYO15A, KIF6, KIF26B, KIF3A, DNHD2, DMN, DYNC2H1, STARD9, MYOHD1, and TPM1, which are involved in cytoskeletal structure, microtubule movement and cell movement, may be associated with asthenospermia, and therefore deserve further studies.

The paper is aimed to establish an artificial neural network (ANN) for predicting mycophenolic acid (MPA) area under the plasma concentration-time curve (AUC) in renal transplantation recipients. 64 Chinese renal transplantation recipients receiving mycophenolate mofetil (MMF) were investigated. 10 timed samples were drawn at different days after transplantation. Plasma MPA concentration was determined by HPLC method and area under curve over the period of 0 to 12 h (AUC(0-12 h)) was calculated using the linear trapezoidal rule. ANN was established after network parameters were optimized using momentum method in combination with genetic algorithm. Furthermore, the predictive performance of ANN was compared with that of multiple linear regression (MLR). When using plasma MPA concentration of 0, 0.5, 2 h after MMF administration to predict MPA AUC(0-12 h), mean prediction error and mean absolute prediction error were -1.53% and 9.12%, respectively. Accuracy and precision of prediction by ANN were superior to that of MLR prediction, and similar results could be found when using plasma MPA concentration of 0, 0.5 h to predict MPA AUC(0-12h). The accuracy and precision of ANN prediction were superior to that of MLR prediction, and ANN can be used to predict MPA AUC(0-12 h).
