Next generation sequencing technologies,providing high speed and throughput that contribute greatly to DNA sequencing,have many applications in clinical virology,including identification of novel or unsuspected viruses,evaluation of human viromes,investigation of viral genetic diversity and evolution,monitoring of antiviral drug resistance,and analysis of virus-host interaction.Meanwhile,due to the complexity in bioinformatics data processing and lack of quality management standards,further efforts and explorations need to be put in the application and quality management of NGS in clinical laboratory.

Objective To investigate the relevance of liver function and neurobehavior of offspring of SD rats ex-posed to sodium valproate in the second trimester. Methods 30 SD rats at 12. 5 d of pregnance were randomly di-vided into three groups: low-dose group (300 mg/kg VPA was injected into abdominal cavity), high-dose group (600 mg/kg VPA);control group (normal saline). The offspring of low-dose groupe were grouped as VPA-low-dose;the offspring of high-dose groupe were grouped as VPA-high-dose; and the offspring of control group were grouped as control group. Then, we tested the liver and neurological function of each group of offspring, respective-ly, and analyzed their relevance. Results The levels of serum total protein and albumin of the high-dose group were considerably lower than these of the low-dose group which were significantly lower than these of control group ( P<0. 01 for both total protein and albumin);the levels of ALT, AST and blood ammonia of the high dose group were drastically higher than these of the low dose group, which were dramatically higher than these of control group ( P<0. 01 ) . The duration and of stereotyped movement disorder in experimental group was markedly longer than this of the control group, while this of the high-dose group was notably longer than this of the low-dose group ( P<0. 01 );the frequency of the stereotyped movement disorder of experimental group was significantly more than this of the control group, while this of high-dose group was obviously more than this of the control group (P<0. 01). In the Morris water maze, the escape latency of the high-dose group was remarkably longer than this of low-dose group, which was observably longer than this of control group (P<0. 01);the swimming distance of the high-dose group was tremendously shorter than this of low-dose group, which was considerably shorter than this of control group ( P<0. 05 , P<0. 01 ) . Correlation analysis of liver function and neural behavior showed that the neurobe-havioral abnormalities were negatively correlated with level of total protein and albumin, and were positively related with the level of blood ammonia, ALT and AST ( P<0. 01 ) . Conclusion The VPA exposure in the second tri-mester leads to the decrement of serum albumin and total protein and to the increment of AIL, AST and blood am-monia;and it also causes the neurobehavioral abnormalities of offspring. The reduction of synthesis of liver albumin and the rise of ALT, AST and blood ammonia can influence the neurobehavioral abnormalities. And there were both of the factors which result in the neurobehavioral abnormalities of offspring exposured to VPA in the second trimes-ter.

Objective To evaluate the effect of combination of phacoemulsification and trabeculectomy on patients with cataract and glaucoma.Methods 19 patients(23 eyes)with co-existing glaucoma and cataract were treated with triple procedure by means of scleral tunnel flap.The mean follow-up period was(15.8 ±3.5)months.Results Compared with preoperative visual acuity,16(64%)of 25 eyes had a best corrected visual acuity of ≥0.6 at the last follow-up(0.1～1.0)(P＜0.01);The mean preoperative intraocular pressure(IOP)was(23.01 ±2.63)mmHg which decreased to(14.02 ±2.05)mmHg(P＜0.05 ,P ＜0.01)after treatment.Conclusion The triple procedure is effective for treating patients with co-existing cataract and glaucoma,which could enhance the visual acuity,control IOP and reduce complications.

Objective To evaluate the long-term outcome ofautologous epidermal grafting in vitiligo and its correlated factors. Methods A 1-5 year follow-up of 310 patients with vitiligo, who had been treated by autologous epidermal grafting, was carried out by questionnaires, phone interview, and clinical revisit. The relevance was estimated between the efficacy of the treatment and several factors, including the time length from the grafting to the follow up, patients' age and gender, location of lesions treated, Koebner phe-nomenon on the donor sites, and the combination therapy with narrow band-ultraviolet B (NB-UVB). Results Of the 310 patients, 161 were males and 149 females with an average age of 26.69±11.76 years; 98 had localized vitiligo, 123 segmental vitiligo, 62 scattered vitiligo, 27 generalized vitiligo. Totally, 24 recipient areas with 1266 sheets were evaluated. Among these sheets, 815 (64.38%) achieved complete repigmenta- tion, 167 obvious repigmentation, 117 some repigmentation, 167 no repigmentation, with a curative rate of 64.38% and total effective rate of 86.81%. Hyperpigmentation occurred in the recipient area of 76 (24.52%) patients, and donor area of 34 patients (10.97%), and hypopigmentation developed in the recipient area of 66 patients (21.29%). Relapse developed in the recipient areas of 30 patients, and new lesions in 12 patients (3.871%). Koebner phenomenon was noticed in the donor sites of 25 (8.064%) patients. The efficacy of autologous epidermal grafting was stable within two years after the therapy, but reduced with the time. Increased efficacy was observed in those sites with little mobililty and large fixity. For example, the best effi- cacy was observed in the legs and arms, followed by feet and hands, chest and back, face and neck, finally by waist and abdomen (P<0.01). NB-UVB exposure could improve the repigmentation. Koebner phe- nomenon in donor sites was associated with a reduced efficacy of epidermal grafting (P<0.05). Gender and age seemed unrelated to the efficacy. Conclusions Autologous epidermal grafting has a good long-term efficacy for the treatment of vitiligo, and transplanted location may be the most important factor affecting the efficacy.

Pancreaticoduodenal anastomotic dehiscence complicated with peritoneal hemorrhage following pancreaticoduodenectomy is a serious complication which threatens patients'life.Prevention and mangement of pancreaticoduodenal anastomotic dehiscence and peritoneal hemorrhage is the focus in the surgical treatment.Operation is the most reliable treatment for bleeding.While reoperation is difficult for most surgeons and the risk of fistula and rebleeding after reoperation exist.Some procedures will affect the endocrine and exocrine function of pancreas.We applied pancreaticojejunal bridge drainage for most patients with hemorrhage after pancreaticoduodenectomy.This procedure is easy,safe,and can protect the pancreatic function.

Objective To compare the results of emergency clinical training for medical students and to put forward some suggestions.Methods Toatlly 207 medical students of Grade 4 studied in the first people' s hospital of Shanghai Jiaotong university from 2009 to 2011 were divided into the traditional group (n =90 ) and the experimental group (n =117 ).The students in the experimental group participated in emergency clinical training in summer vacation while those in the traditional group did not.Questionnaires about their self-learning ability,clinical communicating ability and critical thinking ability after training the were conducted and the data were analyzed by descriptive statistical analysis.Results One hundred and five effective questionnaires were recovered from the experimental group,with the recovery rate 89.7％ and 62 effective questionnaires were recovered from the traditional group,with the recovery rate 68.9％.The scores about clinical communicating ability and critical thinking ability of the experimental group were significantly highcr than those of the traditional group [ (79.45 ± 9.354)vs.(75.87 ± 9.926),(263.38 ± 30.925 ) vs.(251.36 ± 23.679),P ＜ 0.05 ].However,there was no significant difference in scores about self-learning ability between the two groups [ ( 153.97 ± 23.725 ) vs.( 149.83 ± 13.891 ),P ＞ 0.05].Conclusion Emergency clinical training is helpful to improve medical students' clinical communicating ability and critical thinking ability.It is worth popularizing.

Objective To study the current situation of diagnosis and treatment of rudimentary uterine horn pregnancy through 4-cases report. Methods We made a clinical study of 4 cases of rudimentary uterine horn pregnancy admitted to our hospital between 1995 and 2005. Results Three patients had been undergone artificial abortion before they were admitted to our hospital. All the patients were asymptomatic. Ultrasonography was made in 3 cases. Two cases were diagnosed as rudimentary uterine horn pregnancy. Three patients were cured with surgery. Conclusions Rudimentary uterine horn pregnancy is rare and with atypical clinical manifestation in the first trimester. Although diagnosis before surgery is difficult, ultrasonography and MRI make a great role. Surgery is the most important therapeutic method.
