OBJECTIVETo compare clinical efficacy of anatomic locking plate and Gamma nail in treating unstable femoral intertrochanteric fractures with external wall fractures.

METHODSFrom June 2010 to June 2014,clinical data of 44 patients with intertroehanteric fractures associated with lateral wall fractures (type 31A2.2-3.3) followed more than 12 months,which treated with Gamma nail or anatomic locking plate,were retrospective analyzed. Sixteen patients were treated with anatomic locking plate, including 6 males and 10 females aged from 32 to 83 years old with an average of 56.5 years old. Twenty-eight patients were treated with Gamma nail including 17 males and 11 females aged from 26 to 87 years old with an average of 60.4 years old. Operative time, intraoperative fluoroscopy times, blood loss (intraoperative and hidden blood loss), hospital stays were observed and compared. PPMS and HHS scoring were used to evaluate postoperative clinical effect.

RESULTSAll patients were followed up from 12 to 24 months with an average of 16.2 months. Operative time in Gamma nail was shorter than anatomic locking plate; while blood loss( intraoperative and hidden blood loss) and intraoperative fluoroscopy times in anatomic locking plate were less than that of in Gamma nail. There was no significant meaning in hospital stays between two groups. Postoperative full weight-bearing time in anatomic locking plate was prolonged than Gamma nail. At the final following-up, PPMS in Gamma nail was 7.50 ± 1.78 and 6.82 ± 1.38 in anatomic locking plate, and there was no obvious meaning between two groups (t = 2.341, P = 0.132); there was no significant differences in HHS score between Gamma nail (83.25 ± 11.18) and anatomic locking plate (86.14 ± 12.36) (t = 1.923, P = 0.243). The incidence of complications in Gamma nail was less than anatomic lock-ing plate (P = 0.005).

CONCLUSIONAnatomic locking plate for intertrochanteric fractures with external wall fractures could avoid re-injury of external wall, especially for severe comminuted fractures, difficult for intramedullary nailing, and there was no significant meaning in hip joint function compared with Gamma nail, while postoperative incidence of complications was higher than Gamma nail, so early weight-bearing was not stress.

Objective To evaluate the significance of hemihepatic vascular occlusion with extrahepatic control of major hepatic veins for hepatectomy in cirrhotic carcinoma. Methods A retrospective comparative study for hepatectomy in patients with hepatocellular carcinoma(HCC) using Pringle maneuver (groupA,n=44),hemihepatic vascular occlusion(group B,n=76) and hemihepatic vascular occlusion plus extrahepatic control of major hepatic veins(group C,n=85)were made from March 2006 to September 2008.The amount of intraoperative bleeding,time of operation,postoperative liver function,liver function recovering and complications were compared.Results There was significant difference in the amount of intraoperative blood loss between the three groups(543.7 ml、415.8 ml、324.5 ml,respectively,F=98.96,P<0.001).There was no difference in the time of operation.The level of serum alanine transaminase(ALT) and that of serum bilirubin on the 3rd and 6th day postoperatively in group B,and C was significantly lower than that in group A.Conclusions Hemihepatic vascular occlusion with control of major hepatic veins results in selective liver isolation from the systemic circulation,which is more effective than Pringle maneuver for controlling intraoperative bleeding without interruption of hemodynamic stability in liver cancer patients.

For effective inhalable dry-powder drug delivery, tetrandrine-PLGA (polylactic-co-glycolic acid) nanocomposite particles have been developed to overcome the disadvantages of nanoparticles and microparticles. The primary nanoparticles were prepared by using premix membrane emulsification method. To prepare second particles, they were spray dried. The final particles were characterized by scanning electron microscopy (SEM), dry laser particle size analysis, high performance liquid chromatography (HPLC), X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared analysis (IR) and confocal laser scanning microscope (CLSM). The average size of the primary particles was (337.5 ± 6.2) nm, while that second particles was (3.675 ± 0.16) μm which can be decomposed into primary nanoparticles in water. And the second particles were solid sphere-like with the drug dispersed as armorphous form in them. It is a reference for components delivery to lung in a new form.

Objective To learn the prevalence and trends of Brucella disease in Ningxia, in order to provide scientific basis for effective control of the disease. Methods Data of Brucella cases reported through city network from 2004 to 2009 in Yinchuan city, Shizuishan city, Wuzhong city, Guyuan city and Zhongwei city of Ningxia were reviewed and retrospectively analyzed. The data included demographic characteristics, treatment conditions and medical history so on related information. Analytical indicators include reported incidence;with patients' gender, age, regional distribution, urban and rural distribution;become chronic and associated factors;distribution of the cases reporting unit and so on. Results From 2004 to 2009, Ningxia had reported 349 cases of Brucellosis, no deaths, the annual incidence rates reported were 0.017/10 million, 0.543/10 million, 0.151/101 (295/54);The proportion of 34- to 40-year-old age group was higher than other age groups(27.5%, 96/349);Occupational distribution of patients was mainly farmers and herdsmen(70.2% ,245/349), in regional distribution of the patients, the highest percentage was Wuzhong city(61.9%,216/349), followed by Yinchuan city(22.9%,80/349);The proportion of patients in rural areas(97.4% ,340/349) was higher than urban(2.6% ,9/349);the proportion of patients converted to chronic was 11.2% (39/349). With age, the chance of patients converted to chronic was in a decreasing trend(odds ratio was 0.966);cases reported by Centre for Disease Control and Prevention accounted for 74.8%(261/349), by hospital accounted for 25.2%(88/349). Conclusions The reported incidence of Brucellosis in Ningxia is in a rapid upward trend year by year, the patients is mainly young men, the rate of converted to chronic is higher and the ability of hospital in founding and reporting of the cases is weaker.Comprehensive measures should be taken to increase funding, strengthen monitoring, and continuously improve the level of awareness and diagnosis of medical personnel for further strengthen the prevention and control of Brucellosis.

Objective To analyze the clinical features of rectal and perianal inflammatory myofibroblastic tumor and evaluate its diagnosis and treatment.Method Clinicopathological data of 3 cases diagnosed as inflammatory myofibroblastic tumor from January,2005 to June,2011 were retrospectively reviewed.Results Inflammatory myofibroblastic tumor presents as infiltrative growth mass with rich vascularization on CT or MRI,and is difficult to distinguish from hemangioma and other rectal tumors.Preoperative biopsy usually fails to ascertain the entity of mass,and pathological examination of the whole resected specimen with immunohistochemical staining is needed to make final diagnosis.All 3 cases underwent sphincter preserving surgery.One case received a second radical operation 16 months after primary resection because of local recurrence.All patients are followed up to now,with a survival time of 67 months,55 months,and 35 months respectively.Conclusions Rectal and perianal inflammatory myofibroblastic tumor is difficult to diagnose on preoperative imaging examinations or biopsy.Immunohistochemical staining is needed to make final diagnosis.Sphincter preserving surgery with complete tumor removal could achieve long term survival.

To study the effect of the combined administration of different doses of Glycyrrhizae Radix et Rhizoma and Atractylodis Macrocephalae Rhizoma on the proliferation of DFMO-treated intestinal epithelial cells (IEC-6) and p53, p21 mRNA and protein expressions, in order to define the molecular basis for the effect of the combined administration of different doses of Glycyrrhizae Radix et Rhizoma and Atractylodis Macrocephalae Rhizoma on the cell proliferation. The effect of the drugs on the cell division rate and cell cycle of IEC-6 cells was detected by FCM. Quantitative Real-time PCR (qRT-PCR) was used to analyze the effect of the drugs on mRNA of p2l and p53 related to IEC-6 proliferation. Western blot was used to analyze the effect of the drugs on p2l and p53 protein expressions of IEC-6 cells. Atractylodis Macrocephalae Rhizoma could increase p53, p21 mRNA and proteins expression in DFMO-treated IEC-6 cells. The combined administration of different ratios of Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix et Rhizoma could significantly down-regulate Atractylodis Macrocephalae Rhizoma's effect on p53, p21 mRNA and proteins expression in DFMO-treated IEC-6 cells and promote the proliferation of IEC-6 cells. The combined administration of Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix et Rhizoma could down-regulate Atractylodis Macrocephalae Rhizoma's effect on DFMO-treated intestinal epithelial cells (IEC-6).
