Objective To evaluate the therapeutic effects of combining acupuncture and physical therapy with drugs on treating Duchenne muscular dystrophy (DMD).Methods Sixty infants with DMD were randomly divided into a treatment group and a control group (n =30 in each).Both groups were injected with Bozhi glycopeptide and given levocamitine and fructose sodium diphosphate orally.Moreover,the treatment group was additionally given acupuncture and physical therapy.Before and after 90 days of treatment,the time to walk 10 metres and to climb stairs of 2 metres high was measured,as were the serum creatine phosphate kinase (CPK),lactate dehydrogenase (LDH) and aspertate aminotransferase (AST) levels of all participants.Results After treatment,the average walking and stair climbing times of both groups were significantly shorter,and those of the treatment group were significantly shorter than those of the control group.Moreover,the average CPK,LDH and AST levels in the treatment group were significantly lower than before treatment and than those of the control group after treatment.There was a significant difference in the overall response rates,with 93％ observed in the treatment group and 73％ in the control group.Conclusion Combining acupuncture and physical therapy with drugs can significantly increase the mobility and improve the serum CPK,LDH and AST levels of children with DMD.

Objective To investigate the feasibility of fast track surgery (FTS) application in arthroscopic reconstruction of anterior cruciate ligament.Methods A total of 80 cases of anterior cruciate ligament(ACL) tear patients were randomized into two groups.While the experimental group (n =42) was treated with the conception of FTS, and the control group(n =38) was treated with the traditional methods.The postoperative pain, knee Lysholm score, quality of life score (SF-36), knee joint activity (EUROPEP), and postoperative infection were compared between the two groups.Result The VAS score of post-operation pain (VAS) 1 h(1.80±1.13) ,6 h(1.91±0.98), 12 h(1.73±0.95) ,24 h(1.68±0.65) ,48 h(1.69±0.90) ,the time stay in hospital (7 ± 1), total cast (205 600 ± 7 600) yuan, were significantly decreased compared to the traditional therapy group(VAS : (7.00± 1.56), (7.41±0.93), (6.82±1.12), (6.65±0.76), (6.34±0.88) ,P ＜0.05 or P＜0.01;(12± 1) d, P =0.021;(28 600±5 400) yuan, P =0.042).Recovery time of ROM of experimental group was significant lower than control group (P ＜ 0.05).But the comparison of patients, satisfaction of post-operation in two groups was inverse(P=0.007).The Lycholm scores of post-operation of FTS group were remarkably higher than the control group and the scores of prior treatment(85.1 ± 14.2) vs (73.6 ±12.3);P＜ 0.05).Conclusion The new methods of FTS can apparently accelerates recovery after ACL reconstruction,reduces complications, shorten time stay in hospital, cut down the total cost, and improve the experience and the satisfaction of patients.It was safety and feasible.

Objective To investigate the value of whole-liver MR perfusion imaging(MRPI)for early detection of coagulative necrosis after percutaneous ethanol injection(PEI)in rabbit liver VX_2 tumors. Methods VX_2 tumor cell suspension was inoculated into rabbit liver and liver VX_2 tumors[diameter of (2.6?0.6)cm]were induced in 10 male rabbits.MR T_1 WI and T_2 WI were performed to monitor the development of the liver tumor on the 2~(nd)and 3~(rd)week after inoculation.Whole-liver MRPI was performed in the 10 rabbits with liver VX_2 tumors before and 6 days after PEI therapy(1.0 ml ethanol was injected into the most enhanced tumor region under CT guiding).Signal intensity(SI)values of untreated tumor parts and treated areas 6 days after PEI were recorded respectively.The steepest slope(SS)and bolus arrival time (TO)of SI-time curves were measured.The t-Student test was used in statistical analysis of the data.Results There was significant difference in MRPI data between untreated tumor parts[TO:(16.0?1.2)s and SS: 38.9?2.2]and treated areas[TO:(50.8?5.9)s and SS:6.0?1.2]6 days after PEI(t was 15.8 and -39.6 respectively,P

Objective To evaluate the value of intermittent splenic artery occlusion in the treatment of iatrogenic splenic injury and the cause of ischemia reperfusion injury.Methods Experimental animals using dogs were divided into experimental group and control group according to whether the splenic artery was blocked.The animal model of iatrogenic splenic injury was established by general anesthesia.Experimental group was treated with intermittent splenic artery blockage combined with gelatin sponge oppression of the wound to stop bleeding.The first time of splenic artery occlusion was 15 min and continued for 10 min and for another 5 rmin if still bleeding.Then hemostatic effect after removing blocking and oppression was observed.Control group was only treated with gelatin sponge compression to stop bleeding.Blood samples and tissue samples were collected before blocking and after reperfusion for 2 hours in experimental group,and before compression and relieving the compression for 2 hours in control group.IL-1 (interleukin),SOD (superoxide disproportionation enzyme),MPO (myeloperoxidase),MDA (malondialdehyde) and caspase-3 (aspartame acid cysteine protease) were detected.Results The control group still had bleeding,while the experimental group had successfully stopped bleeding.Serum markers before and after occlusion in the experinental group were IL-1 (124.4 ± 106.8 vs.121.2 ± 105.1),SOD (4.7 ± 2.7 vs.5.2 ± 1.8) and MDA (8.8 ±6.5 vs10.8 ±7.5).There were no significant differences on serum markers in two groups after occlusion/oppression including IL-1 (121.2 ± 105.1 vs.162.8 ± 73.8),SOD (5.2 ± 1.8 vs.4.7 ± 2.8) and MDA (10.8 ±7.5 vs.9.6 ±6.6) (P＞0.05).Histological indicators before and after occlusion in the experimental group included MPO (0.62 ±0.23 vs.0.68 ±0.21) and Caspase-3 (0.90 ±0.29 vs.0.86 ± 0.26),and there was no statistical difference on MPO (0.68 ±0.21 vs.0.86 ±0.23 after two sets of experiments) and Caspase-3 level (0.86 ± 0.26 vs.1.21 ± 0.18) (P ＞ 0.05) in two groups after occlusion/ oppression.Conclusion The therapeutic effect of intermittent splenic artery occlusion combined with gelatin sponge compression hemostasis is safe and effective and without obvious ischemia reperfusion injury.

Objective To improve the diagnosis and therapy of primary renal synovial sarcoma . Methods A single case of primary renal synovial sarcoma was reported .A 54-year-old female presented with left flank pain for six days .Enhanced CT scan revealed a nearly-circular mass with the diameter of 2.0 cm in the superior portion of the left kidney .It showed low and high density with punctate calcification .There were low and high density in left kidney around .A possible diagnosis of left renal tumor with rupturing was given prior to exploratory operation .During the operation , a large hematoma was found on the lateral peri-re-nal fascia, which adjoined with other organs .The hematoma was opened and the 1 000 ml dated clot and blood were removed .The tissue inside the hematoma showed fish meat like .The fast pathologic examination showed sarcomatoid tissue , then the case underwent radical left nephrectomy . Results Gross pathologic examination showed a ashen and fish-liked tumor of 3.0 cm×2.5 cm×1.5 cm with multiple sites of necrosis and hemorrhage .The histopathological examination revealed the tumor cells were spindle shaped .The tumor cells organized as bundle with indistinct border line and larger quantity of mitotic phase , which were positive for BCL-2, vimentin, EMA, CD79a and SMA, but negative for CD34, CK and CD10.A diagnosis of renal syn-ovial sarcoma was then determined .Targeted therapy with sunitinib ( 37.5 mg po qd ) was carried out postopreratively .There was no recurrence and metastasis during the six months following up .

AIM:To investigate the ability of a metal complex ammonium tetrathiomolybdate (ATTM) to re-lease H2 S and its cytoprotective effect on an oxidative injury model .METHODS:Released H2 S was absorbed in a reaction flask from ATTM dissolved in the cell medium .Staining with dichlorodihydrofluorescein diacetate or rhodamine 123 fol-lowed by photofluorography was conducted for the observation of reactive oxygen species ( ROS) and mitochondrial mem-brane potential (ΔΨm) levels, respectively.Cell viability and release of lactate dehydrogenase (LDH) from the cells were measured with commercial kits.RESULTS:Similar to another H2S donor GYY4137, ATTM had an ability to release H2S in the cell medium in a dose-dependent manner .Treatment of human skin HaCaT cells with ATTM at concentrations of 25~400 μmol/L didn’ t significantly alter cell viability .Exposure of the cells to ultraviolet rays or a ROS donor H 2 O2 in-creased the intracellular ROS levels .Treatment with 400 μmol/L H2 O2 significantly reduced the viability of HaCaT cells (P<0.01).However, before the treatment with H2O2, pretreatment with ATTM at 100 and 200 μmol/L markedly pre-vented the H2O2-induced cell injury (P<0.01).In addition, the treatment with H2O2 triggeredΔΨm loss (P<0.01) and LDH release from the cells (P<0.01).Prior to suffering from H2O2 injury, the preconditioning with 200 μmol/L ATTM significantly improved ΔΨm levels ( P<0.05 ) and attenuated LDH release from the cells ( P<0.01 ) .CONCLUSION:ATTM is capable of releasing H 2 S and protecting human skin cells against oxidative injury .

Objective To report clinical manifestations, electroencephalogram (EEG), and the genotypes of two siblings with type Ⅲ Gaucher disease.Methods Two patients with different features were siblings. Their clinical data, signs, peripheral leukocytes acid β-glucosidase activity, andGBA gene were analyzed.Results (1) The proband was a boy. He visited us at the age of nine years old because of hepatosplenomegaly, thrombocytopenia and growth retardation without any neurologic symp-toms. He had normal intelligence but abnormal EEG ifndings. The activity of acid β-glucosidase in his leucocytes decreased to 1.5 nmol h-1·mg-1 Pr (normal range 6.0-16.7 nmol h-1·mg-1 Pr), supporting the diagnosis of type Ⅲ Gaucher disease. (2) The elder sister of the proband was 12 years old. She had tonic-clonic seizure and myoclonus seizure from the age of seven years old. Mild hepatomegaly, abnormal EEG, poor effect for antiepileptics, and progressive deterioration of psychomotor abilities were found. Her blood leucocytes acid β-glucosidase activity decreased to 1.8 nmol h-1·mg-1 Pr (normal range 6.0-16.7 nmol h-1·mg-1 Pr). Two heterozygous missense mutations, c.680A>G, (p.N188S) and c.1342G>C (p.D409H) were detected from the two siblings, respec-tively.Conclusions Patients with type Ⅲ Gaucher disease usually have the onset in childhood with typical features of Gaucher disease without neurologic involvement. Abnormal EEG may be helpful to the differential diagnosis of type I or type Ⅲ. On the other hand, neurologic manifestations could be presented as the ifrst symptom in some patients without viscera enlargement. The patients of type Ⅲ Gaucher disease with the same genotype could have different phenotypes, even between the siblings.

Objective To study the effect of ganoderma lucidum polysaccharides combined with metformin on oxidative stress of type 2 diabetic rats. Methods SD rats were fed with high fat diet for 4 weeks and injected with streptozotocin (30 mg·kg-1 ) to produce type 2 diabetic model. The diabetic rats were randomly divided into diabetes model group, ganoderma lucidum polysaccharides group (600 mg·kg-1 ), metformin group (600 mg·kg-1 ), combination group (ganoderma lucidum polysaccharides 300 mg·kg-1+ metformin 300 mg·kg-1 ), After 12 weeks of treatment, the level of fasting blood glucose was determined, and the activity of superoxide dismutase ( SOD), malondialdehyde ( MDA), catalase ( CAT), glutathione peroxidase (GSH-Px), total cholesterol (TC) and triglyceride (TG) were detected. Results The levels of fasting blood glucose in the treatment groups were significantly lower than that in the diabetes model group (P<0. 01). Furthermore, fasting blood glucose in the combination group was significantly lower than that in ganoderma lucidum polysaccharides group and metformin group (P<0. 01). Compared with diabetes model group, serum TC and TG in the treatment groups were significantly lower (P<0. 05, P<0. 01). Serum TC and TG were significantly lower in the combination group than in ganoderma lucidum polysaccharides group and metformin group (P<0. 05, P<0. 01). Compared with diabetes model group, serum SOD levels in the treatment groups were significantly higher (P<0. 01). Compared with ganoderma lucidum polysaccharides group and metformin group, serum SOD levels in the combination group was significantly higher (P<0. 05). Compared with diabetes group, serum MDA levels in the treatment groups were significantly lower (P<0. 01). Serum MDA in the combination group was significantly lower than that in ganoderma lucidum polysaccharides group and metformin group ( P<0. 05). Compared with diabetes model group, serum CAT and GSH-Px in the treatment groups were significantly higher (P<0. 05, P<0. 01). Serum CAT and GSH-Px in the combination group were significantly higher than those in ganoderma lucidum polysaccharides group and metformin group (P<0. 05). Conclusion Ganoderma lucidum polysaccharides combined with metformin could effectively inhibit oxidantion stress in type 2 diabetic rats. The effect was better than ganoderma lucidum polysaccharides or metformin used alone. The possible mechanism may be related to increased activity of SOD, CAT, GSH-Px in vivo and regulation of dyslipidemia.

Objective:To investigate the effect of early enteral nutrition combined with Bacillus in the treatment of patients with digestive tract perforation.Methods:59 patients with emergency digestive tract perforation were randomly divided into experimental group (EN plus Bacillus,n =31) and control group (TPN,n =28).The patients in the experimental group were given enteral nutrition plus Bacillus after first days (＜ 24 h),and the control group was treated with parenteral nutrition support on the first day after surgery.The average hospitalization time,length of ICU stay,incidence of complications,and serum C-reactive protein in the two groups were analyzed.Results:The average length of hospitalization time,ICU stay,recovery of bowel function and eating time were significantly shorter in the experimental group than in the control group(P ＜ 0.05).There was no significant difference in nutrition index between the two groups during the perioperative period (P ＞ 0.05).The C-reactive protein in the experimental group was significantly lower than that in the control group fourth days after operation (P ＜ 0.05).The incidence of postoperative wound infection in the experimental group was significantly lower than that of the control group (P ＜ 0.05).There was no significant difference in the incidence of other complications.Conclusion:Early administration of enteral nutrition combined with Bacillus can significantly shorten the intestinal function recovery time,decreasethe average hospitalization days,reduce the postoperative wound infection rate and thus improve the outcome of patients with digestive tract perforation.

Human ScFv against botulinum neurotoxin serotype A(BoNTa) was modified by fusing human IgG1 Fc to C terminal of ScFv. ScFv-Fc fusion protein was expressed at high level over 30% of total host cell proteins in E.coli. Recombinant protein existed in inclusion body form. Renatured ScFv-Fc was purified to 90%~95% by Protein G Sepharose column. In vitro ScFv-Fc could bind specific to toxiod BoNTa in ELISA. Recombinant ScFv-Fc had similar relative affinity to parent ScFv and had improved stability.
