Objective To investigate the relationship between quality of life and liver function in patients with chronic viral hepatitis B.Methods Psychological condition was investigated in 536 patients of chronic viral hepatitis B and 200 normal volunteers with self-administered 36-item short-form health survey questionnaire.These patients were divided into four groups based on their liver fuction normal,mild, moderate and severe damage,based on their serum activity of alanine aminotransferase(ALT)and serum level of bilirubin at the time of investigation.The patients with abnormal liver function at the beginning of the study would be retested when liver function recovered to normal level.Before and after comparison was made for those with abnormal liver function by Wilcoxon signed rank test.Trend test for the changes in liver function was performed by Jonckheere-Terpstra test.Results There was significant difference in physical functioning,role limitation due to physical health,bodily pain,general health perception,vitality,social functioning,role limitation due to emotional problems and mental health between patient with chronic viral hepatitis B and healthy volunteers.It was positively correlated with the degree of liver function damage. Scores of general health perception,role limitation due to physical health,role limitation due to emotional problems and vitality were relatively low in patients with chronic viral hepatitis B.Conclusions Quality of life in patients with chronic viral hepatitis B was far worse than that in healthy normal people,which related with their liver function.The more damage to liver function,the worse quality of life.Additional psychological treatment will be helpful for the patients with chronic viral hepatitis B other than drug treatment.

Objective To analyze the clinical characteristics of infants with functional constipation(FC)relating to food allergy(FA)and explore its ways of diagnosis and therapy.Methods The detail clinical information of the patients who corresponded to the criteria of diagnosis of FC and FA simultaneous from Mar.2007 to Dec.2009 were reviewed and analyzed.There were 496 cases of FA,in the FA joint clinic,gastroenterology clinic and pediatric ward,56 cases of them had the symptoms of FC(56/496 cases,11%),diets free and amino acid-based formulae were the treatments of the patients.The 56 cases were analyzed with skin-prick test(SPT),serum special IgE and serum special IgG,and the risk factors attributed to the no response to treatments with Logistic regression.Results Fifty-six cases opened the bowel less than twice a week,and companied with pain,8 patients with soiling once a week at least,10 patients with fecal retention,4 patients with large fecal in rectum.Mother or father with the history of allergy were 22 cases,17 cases,separately,both of mother and father with the history of allergy were 17 cases.The results of SPT,serum special IgE and serum special IgG showed that the patients with different allergens,cow's milk,egg,cod,especially.The patients with FC relating to FA were breast-feed,battle-feed or mix-feed.Treatment relied on amino acid-based formulae,as well as elimination diets in infants,80%of them(45/56 cases)improved.Introducing solid foods,the age of upsetting constipation and premature were the risk factors contributed to the no response to the diet free treatment.Conclusion FA should be consi-dered to contribute to the infants presenting with FC.Diets free and amino acid-based formulae may be effective.

s:The partical coding sequence of E2 gene of 13 Hog Cholera Virus(HCV) field isolates, Shimen strain, Chinese vaccine strain(C strain) and Thiverval strain attenuated by low temperature in France,were obtained by reverse trancriptase -polymerse chain reation (RT-PCR) and sequenced.All size were 251bp.The obtained 224bp sequences were analysed by DNA star and compared with the previously published sequences of Alfort strain ,Brescia strain and other references strains.The results showed that those sequencing fragments of 13 HCV field strains were the sequence of E2 gene of HCV.Compared with Shimen strain,the base substitute of all stains were randomly distributed in the entire sequence,and had not base insert and base gap.The variation most occurred at 3' end. The identity of nucleotide sequence and amino acid sequenceof 22 HCV strains were 78.1%～100%?78.4%～100%. The identity of nucleotide sequence and amino acid sequence of 13 HCV field strains were 78.1%～100%?78.4%～100%.The identity of nucleotide sequence and amino acid sequence of 4 HCV field strains isolated in the 1970s～1980s were 79.0%～88.3%?81.1%～87.8%.The identity of nucleotide sequence and amino acid sequence of 9 HCV field strains isolated in the 1990s were 80.8%～100%?83.8%～100% respectively. This paper showed that the genetic variation of HCV was diversity.

The leakage of genetically engineered microorganism(GEM) at the beginning of operation was the important content for ecological risk assessment when GEM was inoculated in a membrane bioreactor(MBR) for bioaugmentation. The effects of different operating conditions on leaking density and intercepting efficiency of GEM were investigated in a submerged microfiltration MBR at the beginning of operation. The interception characteristics were also discussed. The results showed that different operating conditions had different influences on intercepting efficiency:higher sludge concentration was profit for interception,while higher aeration intensity and flux had opposite effects on interception. When the inoculated density of GEM was 1.0?1010 CFU/mL,the leaking densities varied from 1.0?102 CFU/mL to 2.5?102 CFU/mL under different operating conditions at the beginning of operation and the maximum intercepting efficiency could be higher than 8 lg. The main factors determining intercepting efficiency at the beginning of operation were membrane module interception,sludge adsorption as well as suspended GEM transfer inhibition and their contribution shares under certain conditions were 82.3%,14.9% and 2.8%,respectively. Gel layer formation during MBR stable operation was helpful to increase intercepting efficiency. The contribution shares for GEM interception of membrane module,sludge and gel layer were 75.3%,10.7% and 14.0%,respectively,under certain conditions.

According to the characteristics of sludge samples from full-scale wastewater treatment bioreac-tors, the essential total DNA extraction method for most environmental samples, lysozyme-SDS-phenol/ chloroform method, was modified to improve sample pretreatment, intensify cell lysis and enhance the effi-ciency of impurity removal. Obtain a general total DNA extraction method for industrial sludge samples. Such a method was applied for total DNA extraction of sludge samples from several running full-scale an- aerobic or aerobic bioreactors in Shijiazhuang, China. The results indicated that the modified method was suitable for all the sludge samples in this study, showing the satisfying generality. The extracted total DNA of all sludge samples were pure, with about 1.8 of A260/ A280 ratio. The method was also efficient; with average total DNA yield of over 0.7 mg/g and maximum yield of 0.85 mg/g. Moreover, all the extracted to- tal DNA samples could serve as templates directly to amplify 16S rDNA by PCR. The PCR products could be separated well by denaturing gradient gel electrophoresis (DGGE) and the DGGE band patterns were clear enough to be used for further analysis. All these facts indicated that the total DNA extraction method provided in this study could meet the requirements of sludge samples research, from full-scale wastewater treatment bioreactors, using molecular biology technologies.

Objective To investigate the risk factors of low birth weight infants with food allergy.Methods Forty-nine food allergy children who had been admitted to the neonatal intensive care unit(NICU) of Peking University Third Hospital from Jan.1,2007 to Dec.31,2011 and followed up in the Pediatrics Allergy Clinic after discharged from hospital were involved as food allergy group.Forty-nine children who had been admitted to the NICU of Peking University Third Hospital at the same time and followed up in the Child Health Care Clinic after discharged from hospital but had no manifestations of food allergy were selected by stratified sampling as control group.A questionnaire was designed to record the children's gender,gestation age,mode of delivery,feeding patterns after discharging from hospital,tobacco and alcohol consumption of their parents,allergy history of their parents,the intake of egg of the mother during lactation and the children's introduction of egg.At the same time,their hospital notes were investigated.The diseases they had and the application of parental nutrition,pulmonary surfactant and ventilator were all analyzed.Quantitative data were analyzed with Chi-square,qualitative data were analyzed with t-test.The risk factors of food allergy of the low birth weight infants were examined by unconditional Logistic regression.Results The birth weight,gender,mode of delivery,feeding patterns after discharging from hospital,parents,exposure to tobacco smoke and alcohol,the intake of egg of the mother during lactation and the children's introduction of egg between the 2 groups were no significantly different.The diseases they got and the application of parental nutrition,pulmonary surfactant and ventilator when they in hospital were no significantly different,too.The gestation age,parental history of allergy between the 2 groups were significantly different.The proportion of children of 33-35 weeks and 36-37 weeks gestation age in food allergy group were significantly higher than those in control group,while the 29-32 weeks gestation age were significantly lower than those in control group (x2 =10.312,P =0.016 ;x2 =20.753,P =0.000).But by unconditional Logistic regression analysis,only the one or both parents,history of allergy was the risk factor for the development of food allergy of the low birth weight infants(OR =5.574,P =0.004;OR =14.487,P =0.000).Conclusion Parents history of allergy is related to the development of food allergy of the low birth weight infants.

OBJECTIVETo explore the effect of half circle external fixation for the treatment of open tibial fractures.

METHODSFrom March 2005 to March 2011, 94 patients with open tibiofibula fractures were treated by closed manipulative or Kirschner-wire poking reduction with half circle groove external fixation including 63 males and 31 females with an average age of 39 years old ranging from 17 to 65 years old. Among these patients, 5 cases were cross shaped fractures, 19 were oblique form and spiral fractures, 70 cases were comminuted fractures. According to the fracture Gustilo classification, 49 cases were type IIIA, 45 were type IIIB. The incidence of wound infection, fracture healing time were observed. The function was evaluated according to the Johner-Wruhs standard.

RESULTSAll patients were followed up for 14 to 63 months (averaged 29 months). The wound healing time was from 16 to 39 weeks (means 21.4 weeks). No fracture nonunion, osteomyelitis and calf compartment syndrome occurred. The wounds of 81 cases were healed at the first period,deep wound infection occurred in 2 cases. According to the function Johner-Wruhs evaluation criteria:the result was excellent in 52 cases, good in 37 cases, fair in 5 cases.

CONCLUSIONClosed manipulative or Kirschner-wire poking reduction and half circle groove external fixation can reduce the infection rate of open tibiofibula fractures. For open tibiofibula comminuted fractures, after the half circle groove external fixation for 3 to 6 weeks, a middle Kirschner-wire was removed according to fracture end healing situation to make fixation dynamic and promote fracture healing.

OBJECTIVETo compare the therapeutic effects of peripheral facial paralysis in acute stage by different interventions and explore the better treatments of peripheral facial paralysis.

METHODSOne hundred and thirty one cases of Bell's facial paralysis were randomly divided into three groups. In acupuncture group (44 cases), Dicang (ST 4), Jiache (ST 6), Hegu (LI 4), Yangbai (GB 14) and Taiyang (EX-HN 5), etc. were applied; in electroacupuncture group (45 cases), the selection of acupoints and needling method were same as those in acupuncture group, and the electroacupuncture therapy was applied on Dicang (ST 4), Xiaguan (ST 7), Yangbai (GB 14) and Taiyang (EX-HN 5) in acute stage; in medication and acupuncture group (42 cases), Prednisone and Acyclovir were taken by oral administration, Vitamin B1 and Vitamin B12, were applied by intramuscular injection in acute stage, and acupuncture was applied by the way which was same as that in acupuncture group during quiescent and recovery stages. The curative effects were evaluated by House-Brackmann Grading Scale, and the failed rates were observed by follow-up after one and three months.

RESULTSThe cured and markedly effective rates were 79.6% (35/44), 93.4% (42/45) and 78.6% (33/42) respectively in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.05). The cured rates above tympanichord were 54.2% (13/24), 85.2% (23/27) and 48.0% (12/25) in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.01). There was no significant differences of cured rates below tympanichord among three groups (P > 0.05); and the failed rate in electroacupuncture group was much lower than those in acupuncture group and medication and acupuncture group by follow-up after one and three months (all P < 0.01).

CONCLUSIONThe peripheral facial paralysis is effectively treated by electroacupuncture in acute stage, and it suggests that electroacupuncture should be applied early during the acupuncture treatment of peripheral facial paralysis.

BACKGROUNDSeveral genetic polymorphisms in the endothelial nitric oxide synthase (eNOS) gene are associated with the pathogenesis of rheumatoid arthritis (RA). The objective of the present study was to investigate whether the two SNPs (T-786C and G894T) of the eNOS gene are associated with rheumatoid arthritis risk in a northern Chinese population.

METHODSIn this study, the eNOS genes T-786C and G894T were studied in 196 cases with rheumatoid arthritis and 201 healthy controls with gender, age and ethnicity matched. The two SNPs were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The analyses of association were statistically compared using the chi-square test with SPSS software for Windows.

RESULTSThe frequency of the -786C allele was significantly higher in the rheumatoid arthritis patients than in the healthy controls (19.64% vs. 14.18%, P < 0.05). However, the 894T allele of the eNOS gene was not increased in the rheumatoid arthritis patients compared to the healthy controls.

CONCLUSIONSIndividuals with the -786CC genotype have an increased risk of rheumatoid arthritis. Further study with an increased sample size is necessary for the study of the role of this SNP in rheumatoid arthritis.
