Am investigation was done to identify the best and safe dosage of magnesium isoglycurrhizinate in treating hepatitis B.All 1 50 cases suffering from hepatitis B were randomly divided into five groups as A,B,C,D,E.Cases in group A were treated with magnesium isoglycurrhizinate in 100 mg per day for two weeks sololy,and in group B,C,D,E in 150 mg,200 mg,250 mg and 300 mg respectively.The changes of symptoms,index of hepatic function,clinical effective rates and side-effects were observed from treatment beginning to the end.The results that revealed there were no different effects among groups B to E,but less therapeutic effects in group A,and no obvious side-effects in all groups,suggesting that 150 mg dosage of magnesium isoglycurrhizinate should be a safe and the best dosage for treating hepatitis B.

Objective To study preparation of micronized Shuanghuangpo hydrogel patch and its characteristics of transdermal penetration in vitro. Methods Micronized Shuanghuangpo hydrogel patch was prepared with some macromolecular water-soluble materials as gel base.The content of berberine was determined by HPLC method.Its transdermal penetration in vitro was determined according to the method of Chinese Pharmacopoeia 2010 edition. The rat skin penetration test in vitro was performed by modified Franz diffusion cell method. Results The hydrogel patch had constant content of berberine. Its release property in vitro conformed to Higuchi equation. The penetration of berberine in the hydrogel patch through the rat skin followed zero-order dynamics in 12 h.Its release rate was 7.934μg??(cm2)-1??h1/2 and percutaneous rate was 0.571μg??(cm2)-1??h-1. Conclusion The micronized Shuanghuangpo hydrogel patch is a new transdermal agent with sustained release property.

Objective To evaluate the preoperative value of dual contrast-enhanced ultrasound (DCEUS) on obstructive jaundice.Methods Seventy-nine patients with obstructive jaundice were included.DCEUS (percutaneous transhepatic contrast-enhanced cholangio-ultrasonography combined with intravenous contrast-enhanced ultrasound) was performed preoperatively.The biliary obstruction plane,degree and cause were observed.After surgery,the diagnostic accuracy of DCEUS was compared with final pathologic results respectively.Results The overall accuracy of DCEUS in determining the flat,degree and cause of biliary obstruction was 98.7％,98.7％ and 93.7％,respectively.The DCEUS and golden standard were both almost perfect for assessing biliary obstruction with Kappa values of 0.979,0.837 and 0.975(P =0.000).The overall diagnostic accuracy of obstruction combined with obstruction plane,the extent and cause was 92.4％.Conclusions DCEUS could be considered a feasible,reliable,and exhaustive method for preoperative evaluation of obstructive jaundice.

The interferon-γ testing and the comparative cervical skin test were compared with the simple cervical hypersensitivity test routinely used in our country in herds infected with Mycobacterium bovis, in which 167 infected cattle from 5 herds were tested with interferon-γ testing and the comparative cervical test (CCT) simultaneously and other 106 cattle were tested with other hypersensitivity tests used as control for comparison. In these 167 cattle tested with both tests, 89 cattle were proved to be positive both in interferon-γ testing and CCT using the bovine PPD of Netherland with a coincidence rate of 92.7% (89/96). In 106 cattle the coincidence rate of positive reactions detected by γ-interferon test and CCT was 93.41% (78/83.5), that detected by the routine skin of foreign country was 62.26%(66/106); and that between the hypersensitivity test of China and foreign country was 92.19% (59/64). It is obvious that the interferon-γ testing and CCT seem to have higher coincidence rate and the specificity of the skin tests used in our country was rather low. Consequently, the use of the comparative cervical skin test should be considered to replace the routinely used shin tests.

Objective To approach the effect of health education pathway in rehabilitation of children with cerebral palsy (CP).Methods 240 CP children were divided into the trial group (120 cases) daily practiced by duty nurse according to health education pathway table and evaluated in time, and control group (120 cases) guided by routine Methods . Then, the two groups were compared in the rate of achieving standard and the variation in the course of health education.Results The attendants in the trial group knew more about CP, and their acceptance of prognosis, quality of living, rehabilitation effect and health education effect were better than the other group, the variation decreased significantly in the trial group.Conclusion The procedure and standard of health education can decrease the occurrence of hospital infection, increase the confidence of the attendants, and put the staff and patients in harmony.

OBJECTIVETo discuss the effect of limited head and neck squamous cell carcinomas human papillomavirus(HPV) infection status on the prognosis in different nationalities of Xinjiang.

METHODSThe clinical data of 149 cases of head and neck squamous cell carcinoma from Uighur, Han and Kazak was analyzed. The HPV16/18 infection and viral load was examined.The prognosis was analyzed by cox multiIvar-Iate model. The effect of HPV infection status on prognosis was evaluated.

RESULTSIn this study, Oropharyngeal HPV infection rate was 35.0%, followed by hypopharynx 30.0%, oropharyx was 16.0%. The overall survival rate of 3 years and 5 years was 66.4%, and 39.2% respectively. The clinical stage,N stage and HPV were influencing factors for the prognosis of patients with head and neck squamous cell carcinoma (P< 0.05). N stage and HPV were independent prognostic factors for the prognosis of patients with head and neck squamous cell carcinoma (P< 0.05).

CONCLUSIONSThere is a high rate of HPV infection in oropharynx in head and neck cancer. HPV positive is a protective factor for the prognosis of head and neck cancer, and the risk of death in patients with HPV was 3/5 lower than that of HPV negative patients. HPV viral load may be positively related to the total survival rate. N stage is a risk factor for the prognosis of head and neck cancer. Different nationalities have little influence on prognosis.

Objective: To explore the application effect of a four-dimensional smile design as the leading and facial streamline as the reference system in the aesthetic restoration of anterior teeth. Methods: A case of scattered space in anterior teeth was treated with a four-dimensional smile design and digital aesthetic restoration with ultrathin porcelain veneer. The digital information of the patients was obtained through oral and facial scanning, and a four-dimensional smile design and prediction were carried out. After the treatment plan was jointly determined by doctors and patients, minimally invasive abutment preparation was carried out, and ultrathin porcelain veneer was made and bonded in place. After the operation, the esthetic degree and marginal fit were observed and reexamined one year after the repair. Results : The edges of the ultrathin ceramic veneers were naturally tight, and the color was coordinated, with satisfying pink and white esthetics. The face was more harmonious and natural when smiling. One year after the restoration, the facial aesthetics were wonderful, the abutment teeth and periodontal tissues were healthy, and the patients were satisfied. The results of the literature review showed that the fitting of temporal facial scanning and intraoral scanning data can accurately predict four-dimensional smile aesthetics, simulate the real state of the dynamic smile and pronunciation process, and combine it with facial streamlines to design a natural and coordinated personalized smile for patients with asymmetric faces. However, for patients with occlusal changes, unstable occlusion or temporomandibular joint disorder, it is necessary to add data fitting, such as electronic facial arch and cone beam CT, to more accurately simulate postoperative mandibular movement. Conclusion With a four-dimensional smile design as the leading and facial streamline as the reference system, the whole process digital design assisted the restoration of asymmetric anterior teeth with ultrathin porcelain veneer and had a good effect. The postoperative smiling of patients is harmonious and beautiful, which is in line with the expected effect. Patient participation and satisfaction are high; thus, this method is worthy of clinical promotion.
