Rotavirus capsid protein Vp4 plays an important role in the virus adhering and entering the cells. In this study, a Vp4 gene cloned from a rotavirus strain TB-Chen was highly expressed in E.coli BL21 (DE3). The results of the Western blot showed that the protein possesses specific immuno-reactivities and can be specifically recognized by guinea pig antibodies against rotavirus strain SA11 or Wa. Some Vp4 dimers were formed during renaturation. These data obtained from this study provide a strong basis for further study on the structure and function of the Vp4.

ObjectiveTo observe the rehabilitative effect of patients with shoulder-hand syndrome after stroke by manipulation treatment. MethodsThe patients with shoulder-hand syndrome were randomly divided into two groups, manipulation group (180cases) and control group (128 cases). Patients in the manipulation group were regularly given a passive quantitative movement on shoulder, elbow and hand joints,while patients in the control group were irregularly given a passive movement or ordered to perform an autonomic movement. The signs and symptoms of patients in these two groups were not much different. The rehabilitative effects were compared 3 months later. ResultsSigns and symptoms in the manipulation groups improved much better than that of the control group. Conclusions The manipulation treatment for the post-stroke patients with shoulder-hand syndrome is the method that is simple, effective and easy to perform.

OBJECTIVETo evaluate the efficacy and safety of tiaogan Lipi Recipe (TLR) in treating non-alcoholic fatty liver disease (NAFLD) patients of Gan stagnation Pi deficiency syndrome (GSP-DS).

METHODSA randomized, double blind, placebo-controlled clinical trial was performed. Totally 99 NAFLD patients of GSPDS were randomly allocated into two groups, 66 patients in the treatment group (treated with-TLR, one dose per day) and 33 patients in the control group (treated with placebos, one dose per day). The therapeutic course for all was 12 weeks. All patients received lifestyle interventions including moderate aerobic exercise, moderate caloric restriction, and dietary changes. Clinical symptoms, CT indices, liver functions and blood lipids were observed before and after treatment.

RESULTSAfter 12 weeks of treatment, the total score of clinical symptoms decreased in the two groups (P <0. 01), and it was lower in the treatment group than in the control group (P <0. 05). Liver/spleen CT ratio increased in the treatment group (P <0. 01), and it was higher in the treatment group than in the control group (P <0. 01). After treatment levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) all decreased in the treatment group (P <0. 05, P <0. 01), while levels of ALT decreased in the control group (P <0. 05). Besides, all the 3 levels mentioned above were lower in the treatment group than in the control group (P <0. 05). Levels of total cholesterol (CHO) and triglyceride (TG) decreased in the two groups (P <0. 05), and they were lower in the treatment group (P <0. 05). Total effective rates of TCM syndrome, abdominal CT, liver functions, and blood lipids were 79. 69% (51/64 cases), 54. 69% (35/64 cases), 67. 65% (23/34 cases), and 67. 39% (31/46 cases) in the treatment group, while they were 56. 25% (18/32 cases), 25. 00% (8/32 cases), 33. 33% (6/18 cases), and 55. 56% (10/18 cases) in the control group. All were superior in the treatment group (P <0.05, P <0.01, respectively).

CONCLUSIONTLR combined with lifestyle intervention could safely and effectively improve clinical symptoms of NAFLD patients of GSPDS, elevate liver/spleen CT ratios, and play a role in liver protection, anti-inflammation, and lowering blood lipids.

Objective To evaluate the functional outcomes and complications of patients with bone tumors who were treated with the excision-alcoholization-replantation (EAR) method. Methods From August 1965 to August 2003, 191 patients treated with the EAR method who had suitable follow-up were evaluated in our department, including 102 males and 89 females with an average age of 20 years (range, 10-62). On the basis of Enneking tumor staging, 136 patients were identified II B stage, 25 I B stage, and 30 invasive benign tumors and tumor-like lesion. The length of the resected part ranged from 5 cm to 26 cm, with marginal resection in 30 cases, wide resection in 116. The oncological parameters that were evaluated included survival of the patients, local recurrence, and metastasis. Complications included non-union, infection, and fracture of the grafts. Mankin evaluation system was used to assess functional outcomes. Results The mean follow-up time was 32 months (range, 1-372), 52 patients died with disease at the final follow-up. Five-year survival rates of high grade sarcoma and low grade sarcoma were 59% and 90%, respectively, with statistical significance (P=0.02). Lung metastasis were demonstrated in 52 patients (27.2%, 52/191), 51 (26.7%, 51/191) had local recurrence. Except the tumor factor, the total complication rate was 50.3%(96/191). Local complications included 33 nonunion (17.3%, 33/191), 39 fracture of the grafts (20.4%, 39/191), 39 infections of the graft (20.4%, 39/191), 15 fracture of internal fixation (7.9%, 15/191), 5 instability or semiluxation of the joint (2.6%, 5/191). The 5-year survival rate of inactivated bone was 55%. On the basis of Mankin functional evaluation, the satisfied rate was 50.3%. At last there were 141 patients (73.8%, 141/191) preserved their extremities. Conclusion Compared to other methods in the same period, EAR method is considered on the same level of safety in oncology, which superiorities are economic-applicable to patients and the well fitness of bone graft with the defects.

Objective To investigate the enhancement patterns of hypervascularized breast tumors with real time contrast-enhanced ultrasound (CEUS) and to evaluate the accuracy of CEUS in comparison with power Doppler in the discrimination purpose. Methods CEUS was preoperatively performed in 35 patients with 37 hypervascular breast lesions detected on power Doppler. The patterns of enhancement were analyzed and compared with morphological characteristics of the vessels displayed by power Doppler. Results Considering initial lump enhancement and peripheral flake enhancement as a criterion suggesting malignancy, CEUS showed a sensitivity of 90.9% ,a specificity of 73.3% and an accuracy of 75.70/00. While the morphological characteristics of the vessels demonstrated by power Doppler showed no significant difference between benign and malignant lesions, Conclusions CEUS is more accurate than power Doppler ultrasound in the assessment of blood flow of hypervascular breast tumors and more helpful in the differentiation role.

Objective To explore the clinical feature, gene mutations and treatment of isolated hypogonadotropic hypogonadism (IHH). Methods The clinical data from a case of IHH and his families were retrospectively analyzed. The related literatures were reviewed. Results The propositus was a 7-year-old boy with a small penis and testes, whose younger brother was 5-year-old with a small penis and cryptorchidism. In both boys testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH) levels were low. The GnRH provocation test was not reactive. Their parents denied the consanguineous marriage. Illumina sequencing revealed that both of the brothers had homozygous mutation of GnRHR gene in C.806C>T, and their parents were heterozygous mutations in C.806C>T gene. After confirmation of the diagnosis, human choronic gonadotropin (hCG) treatment was given. The levels of testosterone and dihydrotestosterone were significantly increased after 6 weeks. Conclusion The combination of clinical phenotype, biochemical analysis, and gene detection is helpful for early diagnosis of IHH.

[Summary] Microcephalic or Majewski's osteodysplastic primordial dwarfism type Ⅱ ( MOPD Ⅱ) is an extremely rare genetic disease mainly caused by pericentrin ( PCNT) gene mutations. This paper reported one 13-year-old boy, who was admitted because of the slow growth for more than 13 years and deepened skin color over six months. He was diagnosed as MOPD Ⅱ associated with a combination of growth hormone deficiency, type 2 diabetes, hypertension, acanthosis nigricans, multiple café-au-lait spots. On magnetic resonance imaging of brain, no vascular malformations such as aneurysms were shown. There were novel compound heterozygous mutations of PCNT gene in the patient, with the nonsense mutations of c. 502C > T ( p. Gln168 * heterozygous variation) and c. 3103C > T (p. Arg1035* heterozygous variation). His father carried a nonsense mutation c. 3103C > T ( p. Arg1035 *heterozygous variation ) and his mother had a nonsense mutation c. 502C > T ( p. Gln168 * heterozygous variation). After treatment with metformin for three months, his blood glucose returned to normal, and acanthosis nigricans was improved. It seems critical to evaluate the abnormal condition of blood vessels regularly for MOPD Ⅱpatients with PCNT gene mutations.

Objective To compare the clinical efficacy of laparoscopic repair of laparoscopic transabdominal preperitoneal(TAPP)and Lichtenstein tension-free repair herniorrhaphy in the treatment of recurrent inguinal hernia in adults,and to explore the clinical advantages of TAPP in the treatment of recurrent inguinal hernia.Methods A retrospective analysis was conducted in 54 adult patients with recurrent inguinal hernia from December 2010 to January 2015.The patients were randomly divided into TAPP group and Lichtenstein group.The operation time,intraoperative bleeding volume,postoperative hospitalization time,cost of hospitalization,postoperative complications,early postoperative pain and the recurrence of hernia were compared between the two groups.Results All patients were successfully completed surgery.The operation time of TAPP group (47.2 ±9.4)min was significantly shorter than (73.1 ±10.4)min of Lichtenstein group (t=-2.503,P=0.034).The median amount of bleeding during operation of TAPP group was 40(15 -110)ml,which was significantly less than 73(11 -130)ml in Lichtenstein group (t=-6.018,P=0.000). Postoperative hospital stay of TAPP group[(6.5 ±1.4)d]was shorter than (8.2 ±1.6)d of the Lichtenstein group (t=-2.613,P=0.028).Early postoperative pain score of TAPP group[(1.8 ±1.2)points]was better than (2.9 ± 1.4)points in Lichtenstein group (t=-7.006,P=0.000),the difference was statistically significant.However,the hospitalization cost of TAPP group[(8 842.8 ±415.2)yuan]was higher than (6 676.9 ±327.6)yuan of the Lichtenstein group,the difference was statistically significant(t=6.782,P<0.05).In TAPP group,2 cases had complications after operation,which were less than 5 cases of Lichtenstein group.Postoperative follow up ranged from 6 to 48 months,1 case of recurrence in Lichtenstein group,the recurrence rate was 3.8%.There was no recurrence in the TAPP group.Conclusion TAPP has the advantages of short operation time,less bleeding,rapid postoperative recovery,less postoperative pain and so on.It can be used as a recommended procedure for the treatment of recurrent inguinal hernia in adults.

Objective To investigate the characteristics and essential points of diagnosis and treatment of double trisomy 47,XXX/48,XXX,+8 combined Behcet disease, a rare inherited immunodeficiency disorder. Methods The clinical manifestations, karyotype analysis and gene test results of the patients were analyzed, and relevant literatures were reviewed. Results A 11-year-old girl presented repeated fever for more than 6 years, accompanied with recurrent genital herpes infection and oral apthosis, was clinically diagnosed with Behcet disease. Cytogentic and molecular karyotyping on peripheral lymphocytes demonstrated 47,XXX[12]/48,XXX,+8[18]. Conclusions Conventional karyotype analysis and chromosomal microarray analysis have a complementary role in the diagnosis of the disease. We conclude that patients with constitutional trisomy 8 and those with trisomy 8 confined to the bone marrow are both at increased risk of developing features of Behcet disease. The mechanism may relate to increased gene dosage of candidate genes for Behcet's disease on chromosome 8.

Objective To investigate the causes and prevention of postoperative pain of laparoscopic transabdominal preperitoneal (TAPP) and Lichtensteinrepair in the treatment of adult recurrent inguinal hernia.Methods Sixty adult recurrent inguinal hernia patients were enrolled in this study.They were divided into TAPP group and Lichtenstein group by random digits table,with 30 cases in each group.At 6 h Mter operation,the pain degree was evaluated by visual analogue scale (VAS) and compared between two groups.The level of VAS in TAPP group was (3.76 ± 1.47) scores,in Lichtenstein group was (6.36 ± 1.54) scores,and there was significant difference (t =-5.978,P =0.000).In TAPP group,pain was mainly moderate (17 cases,56.67％) and mild (11 cases,36.67％).In Lichtenstein group,pain was mainly moderate (14 cases,46.66％) and severe (13 cases,43.33％).Postoperative follow-up ranged from 6 to 48 months.No chronic pain appeared in TAPP group.There were 4 cases with chronic pain in Lichtenstein group,and the incidence rate of chronic pain was 13.3％.Conclusions The operation of TAPP in the treatment of recurrent inguinal hernia in adult patients has the advantage of shorter operation time,less postoperative pain,faster postoperative recovery,and can effectively reduce the incidence of postoperative pain.
