Objective To explore therapy effect of different operational strategy on tuberculosis of cacroiliac joint with anterior-posterior giant abscess.Methods Fifteen cases were selected as our subject,who suffered with tuberculosis of cacroiliac joint with anterior-pesterior giant abscess from Apr.2005 to Oct.2009.Seven cases underwent focus clearance merely through posterior approach whereas the other 8 cases received focus clearance through anterior-posterior combined approach.We followed-up the cases postoperatively and compared the status of ambi-operation period and tuberculosis' turnover.Results In the posterior approach group,operational periods was (1.9 ± 1.3) h,hemorrhage volume was (487 ± 225) ml,of which 3 cases suffered from abscess relapse postoperatively.In the combined approach group,operational periods was (3.6 ± 1.8) h,hemorrhage volume was (765 ± 538) ml,of which I cases suffered from sinus tract formation postoperatively.Conclusion For patient with tuberculosis of cacroiliac joint with anterior-posterior giant abscess,it has the less relapse rate of the anterior-posterior combined approach than posterior approach.

Objective To investigate anti-ulcerative drug use in patients undergoing arthroscopic operation against stress ulcer. Methosds A total of 297 patients undergoing arthroscopic operation during Jan. to Aug. 2013 in our hospital were recruited and retrospectively analyzed with Excellspreadsheet. Results Among 297 patients in the study, ninety-four patients (31.6%) used AUD before operation, most (94.9%) administered by intravenous, and drug utilization index was 1.35. Ninety-eight point nine patients used proton pump inhibitors (PPIs) in which Lansoprazole was prescribed most. Conclusion This study highlights the overuse of PPIs in patients undergoing arthroscopic operation.

Objective To evaluate the treatment effect of later course accelerated hyperfractionated radiotherapy with chemotherapy for stage Ⅲ and ⅣA nasopharyngeal carcinoma. Methods 116 patients with stage Ⅲand Ⅳ s nasopharyngeat carcinoma were randomly divided into three groups: the conventional fractionation radiotherapy(CFR, 38 cases), the concurrent radiochemotherapy group(CCRT, 39 cases) and the later course accelerated hyperfractionated radiotherapy combined with chemotherapy group (LCAF+CT, 39cases). CFR group was treated with 60Co γ rays and X rays. When the patients had received the dose of 36～38 Gy through composite faciocervical fields, changed into preauricular fields, the total dose was 70 ～75 Gy.And the total dose of cervical metastasis lymph nodes were 70～80 Gy. CCRT group was treated with DDP and 5-Fu. LCAF+CT group was treated with accelerated hyperfractionated radiotherapy. When the dose of composite faciocervical fields had reached 36～38 Gy, changed the fields and treated with accelerated hyperfractionated radiotherapy, 1.3 Gy/fraction, twice daily. The total dose was 69.8～75 Gy. And the chemotherapy drugs was similar to CCRT group. Results The positive response rate among LCAF+CT, CCRT and CFR groups were 94.9 %, 89.7 %, 76.3 % respectively. The complete response rate in the nasopharyn of LCAF+CT group was higher than CFR group(P ＜0.05). The local control rates of one, two and three year of three groups were 100 %, 97.4 %, 89.5 %, 94.9 %, 84.6 %, 68.4 % and 89.7 %, 74.4 %, 57.9 %respectively; and the survival rates of one, two and three year of three groups were 100 %, 92.3 %, 84.2 %;89.7 %, 84.6 %, 71.0 % and 79.5%, 76.9 %, 57.9 % respectively. There were obvious difference between LCAF+CT and CCRT groups in local control rate and survival rate. But there were no difference between LCAF+CT group and CCRTgroup, and also between CCRT group and CFR group. Conclusion The later course accelerated hyperfraetionated radiotherapy combined with chemotherapy can promote disappearance of primary lesion and improve the local control rate and survival rate of patients with stage Ⅲand ⅣA nasopharyngeal carcinoma.

Objective To investigate the status of Helicobacter pylori and “Helicobacter macacae” infection in rhesus and cynomolgus monkeys in China.Methods With the use of 16S rRNA specific primers for Helicobacter spp and Helicobacter pylori ( HP ) from published literatures, and new 16S rRNA specific primers designed for “Helicobacter macacae” ( HM ) , we investigated the infection status of these two Helicobacter spps in both of 45 rhesus and 90 cynomolgus monkeys by qPCR or conventional PCR on stool samples.Results All three primer sets for 16S rRNA exhibited excellently sensitivity and specificity.Both the infection rates of HP and HM were 100% among 45 young adult rhesus monkeys.The infection rate of HP and HM in 90 young adult cynomolgus monkeys were 100% and 97.8%, respectively.Conclusions Helicobacter pylori and “Helicobacter macacae” are present in almost every artificially bred adult rhesus and cynomolgus individuals which may adversely affect the health of laboratory monkeys and the accuracy of related animal experiments.

Objective To explore the efficacy of Xipayigingiva consolidation gargle for root canal flushing. Methods 543 teeth in 543 patients with acute or chronic pulpitis or apical periodontitis who needed root canal treatmentwere divided into three groups by completely randomized design. The three groups wereXipayigingiva consolidation gargle group, hydrogen peroxide group, and sodium hypochlorite group. Conventional pulp chamber incision, pulpectomy and root canals preparation were used for the affected teeth. Three different rinsing solutions were applied to flush root canal. One week later , signs and symptoms were observed , and success rate was assessed in patients by comparing among the three groups. Results Regardless of duration of disease course and patients′ oral health situation, the success rate did not differ significantly among the three groups (P > 0.05). Conclusions Xipayi gingiva consolidation gargle has the same effect as sodium hypochlorite and hydrogen peroxide. It can be used as an alternative for flushing root canal.

Objective To analyze the expression and significance of adiponectin in serum and placenta tissue in preeclampsia pregnancy women.Methods Serum adiponectin levels were measured by Enzyme-linked immuno sorbent assay (ELISA) in 52 cases of normal pregnant women (control group),58 cases of mild preeclampsia pregnancy women (mild preeclampsia group),and 55 cases of severe preeclampsia pregnancy women (severe preeclampsia group).Insulin resistance was estimated using the homeostatic model assessment-insulin resistance index (HOMA-IR).The expression of adiponectin in placenta tissue was detected by immunohistochemical SP methods in three groups.Results Fasting glucose level in severe preeclampsia group was higher than that in control group and mild preeclampsia group [(5.56 ± 1.37) mmol/L vs.(4.55 ± 0.51),(4.68 ± 0.66) mmol/L],fasting insulin level and HOMA-IR in mild preeclampsia group and severe preeclampsia group were higher than those in control group [(14.19 ±3.42),(14.90 ±6.64) mU/L vs.(9.87 ± 1.75) mU/L,1.04 ±0.37,1.18 ±0.56 vs.0.67 ±0.21],serum adiponectin level in severe preeclampsia group was higher than that in control group and mild preeclampsia group [(15.79 ± 4.86) mg/L vs.(11.47 ±3.50),(11.92 ± 2.96) mg/L],the differences were statistical significance (P ＜ 0.05).There was no difference of adiponectin expression levels in placenta tissue among three groups (P ＞0.05).There was no significant correlations between serum adiponectin level and HOMA-IR,expression levels of adiponectin in placenta tissue(P ＞ 0.05).Conclusions Serum adiponectin levels and HOMA-IR are higher in the severe preeclampsia pregnancy women.Increased serum adiponectin levels may be an appropriate feedback regulation in preeclampsia pregnancy women.

BACKGROUND:Knee joint function limitation often occurs after internal fixation of complex femoral condyle fractures, but the mechanism and its influencing factors are also unclear.
OBJECTIVE:To screen and analyze the relevant factors of knee joint function limitation after internal fixation of complex femoral condyle fractures.
METHODS:We retrospectively summarized postoperative fol ow-up data of 6 and 12 months from 121 patients with complex femoral condyle fractures. Knee joint function recovery was evaluated according to Merchan criteria. A multiple stepwise regression analysis was carried out in terms of gender, age, causes, concomitant injuries, skin and soft tissue injury, fracture type, fixed method, operation time, postoperative plaster fixed situation, healing of postoperative incision, bone healing and postoperative functional exercises, to summarize the relevant influencing factors for knee joint function limitation.
RESULTS AND CONCLUSION:Whether the knee joint function after internal fixation was limited acted as the dependent variable Y, and factors with statistical significance of the single factor analysis served as the independent variable X. We used the multiple stepwise regression analysis for multiple factors analysis. Results showed that the gender of patients (X1), with or without concomitant injuries (X3), soft tissue damage (X4) and operation time (X6), a total of four factors, could not be introduced into the model, suggesting that these four factors had no significant correlation with postoperative knee joint function limitation. Another eight factors could be introduced into the factor analysis model, showing that the cause of injury (X2), fracture type (X5), the choice of internal fixation (X7), with or without bone graft (X8), with or without postoperative plaster cast (X9), postoperative knee joint functional exercise or not (X10) and postoperative wound healing (X11), the degree of postoperative bone healing (X12) are closely related to postoperative knee joint function limitation in complex femoral condyles fractures.

And the changes of sublingual collaterals have certain clinical value in judging the condition, stage, treatment and prognosis of diabetes. This article summarized the research progress of sublingual collaterals from two aspects: the relationship between sublingual collaterals and diabetes mellitus and laboratory indexes, and the modern science and technology.

Oxaliplatin-loaded nanostuctured lipid carriers (OP-NLC) were prepared by ultrasonic emulsification method. And its optimal prescription was selected by orthogonal design. The laser light scattering technique, zeta potential analyzer, TEM, DSC, XRD and HPLC were employed to study the physicochemical parameters of OP-NLC, which displayed in terms of particle size, zeta potential, crystalline, drug loading and encapsulation efficiency. The results showed that OP-NLC had an average diameter of (111 +/- 20) nm, zeta potential of (-27.4 +/- 13.1) mV, encapsulation efficiency of (77.4 +/- 2.5) % and drug content of (0.8 +/- 1.5) mg mL(-1). TEM, DSC and XRD indicated that OP-NLC was spherical and the drug was dispersed as nanoparticles by means of non-crystalline. The in vitro release test showed that the drug could be sustained-released from NLC in buffer solution (pH 4.5) after a burst release in initial phase.

Objective To explore the clinical result and complications of noncyclic-PPH surgery in treating internal hemorrhoids.Methods In this study,we evaluate the clinical outcome,such as clinical efficacy,operation time,length of hospital stay,postoperative pain degree and incidence of complications in 120 hemorrhoid patients,randomly divided into control group (60 cases) and observation group (60 cases)based on digital table method,receiving respectively noncyclic-PPH,or PPH (procedure for prolapse and hemorrhoids).Results Two groups were similar in average operation time and average length of hospital stay (P ＞ 0.05).The postoperative VAS score at each time point,was significantly lower in noncyclic-PPH group than the control group (P ＜ 0.05).Non-cyclic PPH group were also significantly lower in postoperative complications than the control group (P ＜ 0.05).Conclusion Compared with PPH surgery,patients with noncyclic-PPH have fewer pain complications or trauma.
