OBJECTIVE To investigate the distribution of familial hepatitis B virus (HBV) genotypes and analyze the relationship between genotypes and clinical outcome. METHODS A total of 136 cases of familial hepatitis B were involved in this study,including 25 cases of asymptomatiec HBV carriers (ASC),85 cases of chronic hepatits B (CHB),24 cases of liver cirrhosis (LC) and 4 cases of hepatocellular carcinoma (HCC). Nested polymerase chain reaction-restriction fragment length polymorphism (ntPCR-RFLP)was used to identify the genotypes of HBV. RESULTS There were 124 cases with hepatitis genotype C,7 cases with genotypes B+C mixed,3 cases with genotype B and 2 cases that did not conformed to be any of genotypes from A to H. Genotype C in the HCC was predominant genotype (100%),next in the LC(96%),CHB (95.3%) and ASC(66.7%).Compared with genotype C,genotypes B and B+C only existed in ASC and CHB,the proportion was 9.5% vs 23.8% and 1.2% vs 2.3%,respectively. There were no other HBV genotypes from A to H seen in familial hepatitis B in Shanxi province. CONCLUSIONS HBV genotype C is the major one in familial hepatitis B in Shanxi. There are a few genotypes B and B+C existed. Genotype C induces a relatively bad prognosis.

BACKGROUND:Percutaneous vertebroplasty for treatment of osteoporotic vertebral compression fractures has achieved very good results.
OBJECTIVE:To discuss and resolve some problems related to thoracic and lumbar vertebroplasty.
METHODS:225 patients (78 males and 147 females) aged 53 to 92 years old were included in this study. They al accepted percutaneous vertebrolplasty and we observed and made a record about some questions related this surgery during perioperative period.
RESULTS AND CONCLUSION:Six cases (2.7%) missed diagnosis. More than two-third of the compression degree were found in sixteen cases (7.1%). Forty-five (12.8%) vertebrae suffered from bone cement leakage in twenty-nine cases (12.9%). Recurrent fractures appeared in ten cases (4.4%). Multiple vertebrae fractures appeared in seventy-nine cases (35.1%). (1) Strategies for missed diagnosis:conduct preoperative physical examination careful y;avoid missing the point of pain;increase MRI scanning when necessary. (2) Coping strategies for severe vertebral fractures:place the needle into the paral el endplates as far as possibly;puncture along the lumbar spine pedicle base and the lateral thoracic pedicle. (3) Coping strategies for cement leakage:when cement leakage over the lower edge of the end plate occurred in operation, we should immediately put the C-arm X-ray machine into anteroposterior position to determine the orientation of the leakage and stop injecting;we should continue to inject the bone cement into the no leak-side to ensure the fil ing amount of vertebral bone cement. (4) Coping strategies for recurrent fractures:reoperation. (5) Coping strategies for multiple fractures:patients with multiple fractures often have a feature of poor constitution and more complications. So, it is necessary to shorten the operation time, and determine unilateral or bilateral puncture ways depending on the degree of vertebral compression to save operation time.

AIM: To investigate the anticoagulant effect of pravastatin and low molecular weight heparin (LMWH), as well as their combination, over time, in a rat model of experimental nephrotic syndrome. METHODS: Healthy SD male rats were chosen randomly to perform nephrotic syndrome models by single injection of adriamycin via tail vein, the matched normal control rats received single injection of equivalent 0.9% sodium chloride instead. After 14 days, the models were set up and randomized into model control group, pravastatin group (pravastatin 2 mg·kg-1·d-1 gavage once a day), LMWH group(LMWH 200 U·kg-1·d-1 intraperitoneal injection once a day) and combined treatment group(pravastatin 2 mg·kg-1·d-1 gavage+ LMWH 200 μ·kg-1·d-1 intraperitoneal injection), then all rats underwent measuring proteinuria every two weeks and fibrinogen, antithrombinⅢ(ATⅢ), D-dimer, platelet count, serum total protein and serum albumin after 4 weeks of treatment. RESULTS: The concentration of fibrinogen and D-dimer in model group was higher significantly than that in control group, and the level of ATⅢ was lower remarkably than that in control group, but platelet count had no obvious change; Compared with model group, pravastatin could increase the level of ATⅢ and decrease the concentration of D-dimer, but the concentration of fibrinogen and platelet count did not change obviously; LMWH and combined treatment could also decrease level of D-dimer, but had no great effects on ATⅢ, fibrinogen and platelet count; all treatment group had no obvious change of serum total protein and serum albumin. CONCLUSION: Adriamycin-induced nephrotic syndrome rat models have hypercoagulability and pravastatin can increase the level of ATⅢ.

Objective:To retrospectively investigate the regulation of cervical and posterior to level V (PLV) lymph node metastasis on clinical target delineation in radiotherapy for nasopharyngeal carcinoma (NPC). Methods:A total of 428 NPC cases from February 2013 to April 2016 were subjected to enhanced CT scan from the base of the skull to the clavicle for pathological diagnosis. A deputy chief physician and an attending physician assessed the nodal distribution in each level in accordance with the RTOG guidelines proposed in 2013. The central point of the metastatic lymph nodes of PLV in the patients were recreated proportionally on the CT images of a stan-dard patient with N0 NPC in reference to the normal anatomy of the PLV area. SPSS 19.0 was used to analyze the correlation between PLV and the other levels. Moreover, the nodal location and characteristics of PLV were analyzed. Results:Among the 428 patients, 381 (89.0%) showed nodal involvement. The top four metastatic probabilities were presented as follows:Ⅱb (75.2%),Ⅶa (60.3%),Ⅱa (59.6%), andⅢ(42.0%). Up to 21 (4.9%) patients exhibited nodal involvement of PLV with 32 nodes. The mean vertical distance of all central points of PLV from the anterior border of the trapezius was 16 mm. Correlation analysis indicated the nodal involvement of PLV with the ipsilateral level Va (P=0.001). Conclusion:NPC showed a high probability of nodal metastasis. Nodes were mostly metasta-sized from the upper to the lower level, as well as from the proximal to the distal area. The leap metastasis rate was very low. The nod-al involvement of PLV correlated with the ipsilateral metastasis of level Va. Thus, the ipsilateral delineation of the posterior border of level V should be contoured to 25 mm far from the anterior surface of the trapezius during the nodal involvement of level Va.

AIM: To observe and compare the improvement of glomerul- osclerosis in rats with 5/6 nephrectomy by valsartan and benazepril. METHODS: Thirty Sprague-Dawley male rats were selected and performed five-sixths nephrectomy to produce chronic renal failure model. Two weeks after the surgery, the rats were randomly divided into model group, valsartan group and benazepril group, and established a shame group serving as normal control. The weight, blood pressure, blood uria nitrogen (BUN) and serum creatinine were measured on the sixth week after operation, then the rats were killed to take the kidneys for pathological histological observation. Immunohistochemistry was used to examine the expression of TGF-? 1 protein and fibronectin (FN) and collagen IV in glomeruli. RESULTS: As compared with model group, systolic pressure decreased (P
