Objective To evaluate the efficacy of lamivudine and adefovir in the treatment of patients with decompensated hepatitis B cirrhosis . Methods 90 cases of patients with hepatitis B cirrhosis of the liver decompensation period from August 2013 to June 2015 in our hospital were researched.According to the random number table method divided into observation group and control group , each of 45 cases, the total course of treatment was one year.The observation group was treated with lamivudine combined with adefovir dipivoxil , control group was treated with lamivudine.The clinical effect, the indexes of liver function, the changes of HBV-DNA and Child-pugh score were compared between the two groups after treatment.Results After treatment, the total effective rate of the observation group ( 93.33%) was obviously higher than that of control group (48.89%), the difference was statistically significant (P<0.05), the observation group alanine amino acid, total bilirubin, aspartate aminotransferase were (71.23 ±21.32)U/L, (28.32 ±4.65)Umol/lL, (4.65 ±9.25)U/L, they were significantly lower than control group (111.54 ±16.25)U/L, (46.53 ±4.89 ) Umol/L, ( 4.89 ±12.11 ) U/L, the observation group albumin ( 39.82 ±2.62 ) g/L was significantly higher than control group (35.55 ±2.22)g/L, the difference was statistically significant (P<0.05), after treatment, the observation group hepatitis b HBV DNA levels, Dhild pugh score (2.78 ±0.45)log10 copies/mL, (6.12 ±1.23) were significantly lower than the control group (3.89 ±0.65)log10 copies/mL, (7.89 ± 1.21)scores, the difference was statistically significant (P <0.05).Conclusion The combination of lamivudine and adefovir dipivoxil significantly decompensated hepatitis B cirrhosis has a curative effect, it could effectively improve the patient's liver function, Dhild-pugh score, HBV-DNA level.

Objective To investigate the value of brainstem auditory evoked potential (BAEP) in early diagnosis of severe hand,foot and mouth disease (HFMD) with the nervous system damage.Methods BAEP was performed in 297 cases with HFMD.The patients were divided into 4 groups by the HFMD clinical classification and their ages.Group A included the general cases who were younger than three years (n =80).Group B included the severe cases who were younger than three years(n =94).Group C included the general cases who were three years or older(n =38).Group D included the severe cases who were three years or older(n =85).The electroencephalogram (EEG) and MRI results of patients in the groups were retrospectively studied and the results were compared with that of BAEP.Results (1) The BAEP abnormal rate of group B (18/94,19.15％)was higher than that of group A (3/80,3.75％),and the BAEP abnormal rate of group D (13/85,15.29％) was higher than that of group C (1/38,2.63％) (P ＜ 0.05).(2) The EEG abnormal rate in group B was low(2/94,2.13％) and there was no case with abnormal EEG in group A.(3) The EEG abnormal rate of group D (49/85,57.65％) was higher than that of group C (6/38,15.79％) (P ＜0.05),and higher than the BAEP abnormal rate of group D.(4) The MRI abnormal rate of group B (9/94,9.57％) was higher than that of group A (1/80,1.25％) (P ＜ 0.05),and the MRI abnormal rate of group D (9/85,10.59％)was higher than that of group C (0).(5) The BAEP abnormal rate of the children with severe HFMD (31/179,17.32％) was higher than the MRI abnormal rate (18/179,10.06％) (P ＜0.05).Conclusion BAEP has clinical significance for early diagnosis of severe HFMD with nervous system damage,and can provide objective basis for the diagnosis.

Objective:To investigate HLA DQA1 alleles distribution in the Yichu of Yangbi county, Yunnan province, compared with other Chinese group Methods:PCR RFLP.Results: Of 8 DQA1 alleles studied, DQA1*0301 (allele frequency 31 63%) is the most common allele in this Yichu, and DQA1*0401 (1 02%) is the rarest Chi square test shows that Yangbi Yichu has no significant difference with six northern Han groups, Man, Singaporean and Uygurs of Xinjiang In contrast, Buyi, Dai and Taiwanese is much more complicated with a significant difference from other groups A similar observation was found in Guangdong Han and Guangxi Zhuang Similar to Kazak, Uygurs showed no significant difference with some of northern Han groups Tibetans have no significant difference with Kazaks and Singaporean Conclusion: DQA1 complexity of southern ethnic group is probably result of mutilple origin or stress of different environment Yangbi Yi ethnic group has characteristic of Northern group

Objective To investigate the influence of different end shapes of esophageal stents on the mechanical behavior of the stent-esophagus system. Methods Through finite element simulation, the mechanical behavior of the coupling system between braided esophageal stents with different end shapes (straight-tube-shaped, cup-spherical-shaped, double-trumpet-shaped) and the esophageal cavity was analyzed. The influences of bare stents and covered stents with three different end shapes on stress distributions in the inner wall of the esophagus and on dilatation of the esophageal stenosis zone were compared. Results The reduction in stenosis rate caused by the bare stent was larger than that of the covered stent. Moreover, the equivalent stress and the contact stress caused by the bare stent were much larger than those of the covered stent. Different end shapes had a significant influence on the stress occurring in the healthy esophageal zone. Stress concentration occurred in the zones where the esophagus contacted the central part of the cup-shaped end and the edge of the double-trumpet-shaped end. The braided esophageal stents with three different end shapes all had good apposition.Conclusions Different end shapes of stents cause different stress states in the esophagus. A larger stress involves a higher probability of occurrence of esophageal tissue hyperplasia, but a smaller possibility of stent migration. Therefore, understanding the effect of the end shapes on stent performance can provide important theoretical references for optimization design of the braided stent and its clinical selection.
