Objective To investigate the clinical efficacy of ganciclovir combined with Bacillus Calmette-Guerin polysaccharide nucleic acid (BCG-PSN) for the treatment of herpes zoster. Methods Eighty-six cases with herpes zoster were randomly divided into study group and control group, 43 cases in each group. Patients of control group received simple ganciclovir treatment; while patients of the study group received BCG-PSN on this basis, then to observe and compare the efficacy, the repair time of skin lesions (herpes stopping, surface deposition), odynolysis time, remained neuralgia incidence and adverse reactions of two groups. Results Patients of two groups all completed the experiment successfully, no one withdraw from this trial because of no tolerance of drugs. The herpes stopping and surface deposition time and odynolysis time of study group were significantly shorter than those of control group, the difference was statistically significant (P＜0.05 ); the remained neuralgia incidence was significantly lower than that of control group,the difference was statistically significant (P＜0.05); the effective rate of study group in 14 days after treatment was 90.7% (39/43) and significantly higher than that of control group [74.4% (32/43)], the difference was statistically significant (P ＜ 0.05);there were no serious adverse reactions occurred in two groups. Conclusion Application of ganciclovir combined with BCG-PSN for the treatment of herpes zoster has certain efficacy, it is feasible and safe.

The effect of gelatin on anaero-cultivation of Bifidobacterium adolescent is and stabilization of its living cell in dried preparation was investigared. It was shown that the well-distributed mixture of gelatin and medium could have a cushioning effect on pH reduction resulting from acid-production while incubating, and the dried mixture comprising living cell of bifidobacterium adolescentis was prepared, in which the stability and viability of cell come from cultures of gelatin mixture was increased compared with that without gelatin mixture. It was shown that oxygen toxicity to anaerobic cell was well reduced because of cell immobilization by the gel mixure after drying with saccharide substance , and then fermentable dynamics in 50L fermentor was tested as well as the relationship of growth kinetics, pH, dissolved oxygen rate, and content of soluble solids.

Objective To investigate the efficacy of aripiprazole addition therapy on adiponectin and leptin in schizophrenia patients with olanzapine-induced weight gain. Methods Schizophrenia patients with clinically significant weight gain induced by olanzapine were randomly divided into two groups:treated with olanzapine+aripiprazole (5 mg/d, n=48) or olanzapine+placebo (n=46). The level of FBS, TG, TC, adiponectin, leptin, the body index (BMI) and the insu?lin resistance index (HOMA-IR) were measured before and 4, 8 and 12 weeks after treatment. Results Adiponectin in?creased and leptin as well as HOMA-IR decreased in olanzapine+aripiprazole group after 4, 8 and 12 weeks treatment (P<0.05). However, FBS, TG and TC decreased and BMI increased only after 8 and 12 weeks treatment(P<0.05). In olanzapine+placebo group, the dadiponectin decreased and leptin, HOMA-IR as well as BMI increased after 8 and 12 weeks treatment(P<0.05). In olanzapine + aripiprazole group the adiponectin, leptin and HOMA-IR of 4, 8 and 12 weeks and BMI of 8 and 12 weeks were different from olanzapine + placebo group(P<0.05). Conclusions In schizo?phrenia patients with olanzapine-induced weight gain, aripiprazole addition therapy can ameliorate the HOMA-IR and BMI probably through the regulation of adiponectin and leptin.

AIM: To investigate the variation of ?-AR in pulmonary microvascular endothelial cells and variation of GRK2 in lung and to explore the therapeutic effect of methlyprednisolone in severe acute pancreatitis-associated lung injury model in rats.METHODS: 36 rats were divided into three groups randomly: the control group,the experimental group,and the intervention group.In the experimental group,severe acute pancreatitis-associated lung injury model was induced in SD rats by retrograde injection of 5% sodium taurocholate into biliopancreatic duct.In the control group,laparotomy was performed,duodenum and pancreas were flipped only.In the intervention group,methlyprednisolone(30 mg/kg) was injected into rump muscle of rats after model developed.At 6 and 12 h after model was developed,the maximum binding capacity(Bmax) and the Kd value of ?-AR were detected in lung by means of radioactive ligand binding assay.GRK2 expression was detected in lung by means of immunofluorescence.RESULTS: The scores of the severity of pancreatitis and the severity of lung injury in the experimental group were obviously higher than those in control group.In the experimental group,Bmax was obviously lower,Kd and GRK2 were obviously higher than those in control group and the intervention group.CONCLUSION: The ?-AR in lung is lower down and GRK2 expression in lung is up-regulated in severe acute pancreatitis-associated lung injury model in rats.The therapeutic effect of methlyprednisolone to severe acute pancreatitis-associated lung injury is positive.

BACKGROUND: Clinical evidence have proved that heterotopic ossification is easily present in bony callus of patients with fracture combined with head injury, and the healing of bone fracture is accelerated obviously. OBJECTIVE: To study the expression and distribution of vascular endothelial growth factor (VEGF) in bony callus among the patients with fracture combined with head injury and simple fracture patients, and to investigate its clinical significance and action mechanism.DESIGN, TIME AND SETTING: Grouping controlled observation was performed in the Xijing Hospital, the Fourth Military Medical University of Chinese PLA between February 2006 and July 2007.PARTICIPANTS: The patients comprised two groups those who had fracture combined with head injury and those who had simple fracture. Each group had 50 patients. The fracture combined head injury group included 41 males and 9 females, aged 19-55 years; simple fracture group included 36 males and 14 females, aged 17-52 years. METHODS: The bony callus specimens were harvested at 7-10, 11-15, 16-20, 21-27 and 28-35 days post-injury. The content of VEGF in bony callus was measured at different phase by using immunohistochemistry methods, and the speed of fracture healing was also observed.MAIN OUTCOME MEASURES: ①X-ray results; ②immunohistochemical image analysis. RESULTS: In different phase of bone healing, the VEGF of the two groups were homogenous, the early expression of VEGF in osteoprogenitor cell, osteoblast and cartilage cell in the fracture combined with head injury group was significantly higher than those in simple fracture group. The osteoprogenitor cell proliferated, and the differentiations of osteoblast and cartilage cell were enhanced obviously. The VEGF level reached the peak at 7-10 days, and kept at the high level for 30 days and then gradually decreased. The peak of VEGF level in simple fracture group came at 11-15 days, kept in the high level for 20 days and then gradually decreased. The peak value in simple fracture group was significantly lower than the fracture combined with head injury group. There was statistical significance in the expression of VEGF between two groups by the paired t-test (P < 0.05). A large mount of osteotylus could be detected at 4 weeks after injury by X-ray in patients with fracture combined, with head injury, but at 7-9 weeks in patients of those who had simple fracture.CONCLUSION: The expression of VEGF in the bony callus in the group of fracture combined with head injury is significantly greater than that in simple fracture patients, and the expression lasts for a longer time. The proliferation and differentiation of osteogenitor call, osteoblast and cartilage cell are also significantly faster in the group of fracture combined with head injury, which might be one of the bone healing mechanisms.

Objective To evaluate factors influencing long-term survival of biliary atresia patients receiving Kasai procedure and the prevention and treatment of surgical complications.Methods Among 97 biliary atresia patients undergoing Kasai or Suruga operation from Mar 1989 to Mar 1999, 35 cases have survived over five years.These 35 cases were classified intraoperatively into type Ⅱ (4 cases) and type Ⅲ (31 cases).Procedures included hepaticojejunostomy (12 cases), Suruga operation (hepaticojejunostomy with a jejunal fistula in 21 cases), hepaticocystomy (2 cases).Six patients underwent second hepaticojejunostomy because of porta hepatis obstruction.Results (1) Eighteen patients suffered from early cholangiolitis, and four cases developed late cholangiolitis, 5-8 years after closing the ascending stoma.(2) Five cases presented upper digestive tract hemorrhage caused by portal hypertension.(3) All patients were followed up from 5 to 15 years with 2 deaths.Conclusion Conventional surgical procedures still take important part in treating biliary atresia before liver transplantation is popularized.Factors influencing long term survival of patients receiving Kasai′s operation include age at operation, pathological classification of extrahepatic bile duct, with or without cholangitis after operation, and portal hypertension.

Objective:To compare the difference of LLD (leg length discrepancy) between robot-assisted and conventional methods of total hip arthroplasty (THA).Methods:Data of 38 patients who had THA performed by robot-assisted or conventional methods from January 2019 to May 2020 were retrospectively analyzed. There were 38 cases (54 hips) in robot-assisted THA group (robot group) with 18 males and 20 females (age 53.5±13.6 years, BMI 26.2±3.4 kg/m 2), and there were 21 cases (32 hips) with osteonecrosis of the femoral head, 17 cases (22 hips) with Crown typeⅠandⅡdevelopmental dysplasia of the hip. There were 38 cases (54 hips) in conventional THA group (conventional group), with 19 males and 19 females, (age 52.3±14.7 years old, BMI 25.7±2.9 kg/m 2), and there were 19 cases (30 hips) with developmental dysplasia of the hip, and 19 cases (24 hips) with osteonecrosis of the femoral head. The operative time, postoperative LLD, Harris score, forgotten joint score-12 (FJS-12) and the difference between preoperative and postoperative LLD between the two groups were compared, and the correlation between surgical methods and the change of hip length was also evaluated. Results:The operation time of the robot group was 73.3±14.1 min and which was 59.3±12.6 min in conventional THA group ( t=2.732, P=0.003). In the robot group, the postoperative LLD was 2.3±3.4 mm, which was less than that of the conventional group 6.7±5.4 mm ( t=3.521, P < 0.001). When the absolute value of LLD was larger than 5 mm as an abnormal value, it was 2.6% (1/38) in the robot group and 47.3% (18/38) in the conventional group. The difference of hip length (HL) in planning and post-operation in the robot group was 2.8±2.2 mm, which was smaller than that in the conventional THA group 7.9±5.3 mm ( t=2.357, P < 0.001). In addition, there was a correlation between the change of hip length results and the postoperative measurement of hip length in the robot group ( r=0.983, P < 0.001). At the last follow-up, Harris score and FJS-12 were recorded in the robot group and coventional group. The scores were 83.1±5.3 and 32.5±4.9 respectively in the robot group, 82.9±7.2 and 31.9±6.7 in the conventional group, respectively. There was no significant difference between the two groups ( t=0.221, 0.356; P=0.819, 0.731). Postoperative bleeding occurred in 1 case in the robot group with postoperative suture healed well. The fracture of the posterior wall of the acetabulum was found in the conventional group and the patient avoids weight bearing 4 weeks after operation. The postoperative recovery was good and no other related complications were found. Conclusion:Robot-assisted THA can accurately restore the length of both legs and reduce LLD compared with conventional THA. The real-time monitoring of LLD during robot operation can give the operator an accurate reference.

Objective To explore the value of intravoxel incoherent motion (IVIM) imaging in evaluating diffusion and perfusion variations in subacute brain infarction.Methods MRI data of 35 patients with subacute brain infarction were analyzed retrospectively,including routine DWI,IVIM imaging and three-dimensional arterial spin labeling (3D-ASL) sequence.The ADC maps were obtained by routine DWI sequence.Pure molecular-based diffusion coefficient (D) maps,pseudo diffusion coefficient of perfusion (D*) maps and perfusion fraction (f) maps were obtained by IVIM sequence.Cerebral blood flow (CBF) maps were obtained by 3D-ASL sequence.ADC,D,D*,f,CBF values and the relative values (rADC,rD,rD*,rf,rCBF) of brain infarction lesion and contralateral mirror area were calculated.All the parameters between brain infarction lesion and contralateral mirror area were compared.The correlations were analyzed between rADC value and rD,rD*,rf values respectively,as well as between rCBF value and rD,rD*,rf values respectively.Results Quantitative analysis showed significant decreases of ADC,D,D*,f and CBF values in the brain infarction lesion compared with those in the contralateral mirror area (all P＜0.05).There were positive correlations between rADC value and rD,rf values (r=0.687,0.601,P=0.005,0.018).And the positive correlation was found between rCBF value and rf value (r=0.581,P=0.022).Conclusion IVIM imaging can concurrently provide the perfusion and diffusion informations of subacute brain infarction patients,which is helpful to further elucidate the mechanisms of subacute brain infarction.
