OBJECTIVETo explore clinical outcomes of posterior malleolar fractures with medial-extension type through posterioromedial and posteriorlateral incision.

METHODSFrom January 2008 to January 2011,25 patients with posterior malleolar fractures with medial-extension type were treated by hollow lag screw. Among them, 15 patients were treated through posteromedial incision,including 9 males and 6 females,aged from 21 to 67 years old with an average of 48.1 +/- 1.3; there were 5 cases with type A, 6 cases with type B and 4 cases with type C,according to Denis-Weber classification. Ten patients were treated by through posterior-lateral incision,including 6 males and 4 females, aged from 23 to 64 years old with an average of 46.9 +/- 1.5; there were 3 cases with type A, 5 cases with type B and 2 cases with type C,according to Denis-Weber classification. Operation time, blood loss, length of incision, times of X-ray exposure and complications of two groups were recorded and compared, Baird-Jackson effective evaluation were applied for evaluate clinical outcomes.

RESULTSAll patients were followed up from 12 to 49 months with an average of 20.6 months. There were significant differences in operation time, blood loss, times of X-ray exposure and complications between two group (P < 0.05). While there was no obvious meaning in clinical outcomes between two groups (P > 0.05).

CONCLUSIONTreating posterior malleolar fractures with medial-extension type through posteromedial approach can expose and fix fracture under direct vision, has advantages of shorter operation time, less X-ray exposure and blood loss, is a good choice of surgical approach.

Abstract： Objective　To analyze the changes of cytokine levels in patients with sensitive pulmonary tuberculosis and drug-resistant pulmonary tuberculosis before and after anti-tuberculosis treatment. Methods　The clinical data of 213 pulmonary tuberculosis patients admitted to the Eighth Affiliated Hospital of Xinjiang Medical University from August 2019 to October 2020 were collected, and divided into a sensitive pulmonary tuberculosis group and a drug-resistant pulmonary tuberculosis group, of which 141 were in the sensitive group and 72 in the drug-resistant group , and the pro-inflammatory factors tumor necrosis factor-α (TNF-α), IL-6, IL-17, interferon-γ (IFN-γ) and anti-inflammatory factors IL-10 and IL-4 in plasma before treatment, 3 months and 6 months after treatment were compared. Results　Compared with the healthy group, the levels of plasma IL-6 in the sensitive group and the resistant group were significantly increased, difference was statistically significant (P<0.01). The plasma levels of IFN-γ and IL-17 in the sensitive group were increased, and the difference was statistically significant (P<0.05). Compared with before treatment, the levels of IL-6 and IL-4 in the plasma of the sensitive group after 6 months of treatment were lower than those after 3 months of treatment, and the difference was statistically significant (P<0.05), and IFN-γ was significantly decreased (P<0.001). After 6 months of treatment, the IL-10 content was lower than that before treatment, and the difference was statistically significant (P<0.05), and the IFN-γ decreased significantly (P<0.000 1). The levels of IFN-γ at 3 months were higher than those in the resistant group, and the difference was statistically significant (P<0.01). After 6 months of treatment, there was no significant difference in the content of IFN-γ between the sensitive group and the resistant group. The effective rate of CT absorption was 70% in the sensitive group and only 43.33% in the resistant group at 3 months of treatment, and there was no significant difference in the effective rate between the two groups after 6 months of treatment. Conclusions　Detection of pro-inflammatory cytokines and anti-inflammatory cytokines in plasma can provide reference for host-directed therapy of pulmonary tuberculosis. Understanding this important feature of cytokines on pathogen-host interactions can provide new insights into the study of virulence mechanisms and may provide new approaches for immune intervention in pulmonary tuberculosis.

OBJECTIVE:To investigate rules and characteristics of ADR induced by antigout agents,and to provide reference for clinical rational drug use. METHODS:A total of 146 literatures,167 putients of ADR induced by antigout agents,which were reported during Jan. 1979-Dec. 2014. RESULTS:Of 167 ADR cases,the ratio of male to female was 5.4:1,and ADR patients aged above 70 years occupied the highest proportion(34.14%);Most ADR were induced by allopurinol(137 cases)ADR induced by antigout agents mainly were dermal system injury(60.00%),systemic reaction(9.19%),urinary system injury(5.95%),etc. and the specific performance manifested as erythra (51 cases),dermatitis exfoliativa (38 cases),drug hypersensitivity syndrome (13 cases),bullous epidermal necrolysis type of drug eruption (11 cases),Stevens-Johnson syndrome (9 cases) and so on. New and severe ADR were 66 cases,13 cases of severe ADR were dead. CONCLUSIONS:ADR induced by antigout agents is common in clinical and should be treated promptly,patient's care also should be strengthen to ensure patient medication safety and improve clinical treatment.

This study was aimed to observe effects of traditional Chinese medicine (TCM) treatment from lung on mRNA expressions of iNOS in lung tissues of rats with ulcerative colitis (UC). A total of 52 rats were used to estab-lish the UC rat model by using rabbit intestinal mucosal tissue allergenic model and TNBS-ethanol model (with the model success rate of 78%). Eight rats, which were randomly selected from 40 successfully modeled rats and the normal group, were used as the model group and the normal group before intervention (time point of week zero). The rest 32 successfully modeled rats were randomly divided into the model group, the western medicine (salazosulfapyri-dine) group, treatment from lung (Huang-Qi Jie-Geng, HQJG decoction) group, and treatment from intestine (Huang-Qi Huang-Lian, HQHL decoction) group, with 8 rats in each group. Another 8 normal rats were used as the control group. The intervention was given for 4 weeks. And the mRNA expression of iNOS was detected in week ze-ro, and four weeks after the treatment using real time-PCR. The results showed that in the acute phase of week zero, the mRNA level of iNOS in lung tissues of model group was significantly increased compared with that in normal group (P < 0.05); after 4-week treatment, compared with the normal group, the mRNA level of iNOS in the model group was significantly increased (P< 0.05). Compared with the model group, the mRNA level of iNOS in the treat-ment from lung group was significantly decreased (P < 0.01). It was concluded that NO which was catalyzed and synthesized by iNOS played an important role in pulmonary diseases. It can cause airway inflammation, edema, lung injury, and etc. Treatment from lung can alleviate the lung injury by inhibiting abnormal activation of iNOS.

Objective To investigate whether catestatin (bovine chromogranin A 344-364) can inhibit the biofilm formation of Candida albicans and examine its relationship with the expression of adhesion gene HWP1.Methods Clinical strains and standard strain ATCC 10231 of C.albicans were studied.XTT [2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide] method was used to assess the ability of C.albicans biofilm formation.Antifungal activity against planktonic Candida ceils was evaluated in terms of minimum inhibitory concentrations (MICs) according to the description in CLSI-M27-A3.XTT assay and colony count were used to assess the effect of catestatin on inhibiting C.albicans biofilm formation.The lowest concentration showing 50 ％ inhibition on biofilm formation (BIC50) was decided by calculating the metabolic activity.The adhesion of C.albicans reduced by catestatin was visualized under an inverted microscope and quantified by colony count.The expression of HWP1 was analyzed by RT-PCR.One-way analysis of variance (ANOVA) and Dunnett's T3 test were used to compare the results.Results Clinical strains and standard strain ATCC 10231 of C.albicans showed strong ability in forming biofilm.Catestatin exhibited MICs ranging from 40 μmol/L to 80 μmol/L against planktonic C.albicans cells,and BIC50 of 80-160 μmol/L in inhibiting C.albicans biofilm formation.Catestatin reduced the adhesion of C.albicans.The colony forming unit (CFU) was 27 822.22-±-2 472.74 in blank control group,while the CFU was 5 355.55± 1 264.03,11 377.78±2 232.58,17 488.89±1 136.27,22 377.78±3 521.99,and 26 044.44±1 329.57 in the presence of 160,80,40,20,and 10 μmol/L catestatin,respectively (F=147.018,P=0.001).The difference between control group and 160,80,and 40 μmol/L catestatin was statistically significant (P＜0.05).RT-PCR found the expression of HWP1 in the presence of 160 μmol/L catestatin was about 12.24％ of that in blank control group.Conclusions Catestatin can effectively prevent C.albicans biofilm formation.This effect may be related to the down-regulated expression of adhesion gene HWP1 by catestatin,which results in reduced adhesion of C.albicans.Promising clinical prospect is expected for this finding.

Objective To discuss clinical effect and feasibility of laparoscopic pelvic lymphadendenectomy assisted radical vaginal hysterectomy (LARVH) in the treatment of cervical cancer. Methods Laparoscopic pelvic lymphadendenectomy assisted radical vaginal hysteretomy was performed in 38 patients with cervical cancer. The operative quality and postoperative recovery effects were analyzed. Results All 38 patients were successfully performed with LARVH and no complications. The radical vaginal hysteretomy were performed in all of patients, 21.4±2.2 pelvic lymph nodes were removed. The average duration of surgery was (240±25.6) min and the average hemorrhage was (340±40.2) ml. There were 7 patients who needed blood transfusion during operation. After operation, the mean time for passage of gas by anus was (2±0.26) days, and the mean recovery time of bladder function was (10.5±1.3) days. Patients were discharged after (9.2±1.1) days on average. 38 patients had no complication. Conclusions For the treatment of uterine neoplasm, LARVH decreased operative damage with more short recovery time, same operative extent as laparotomy. It is an ideal way to treat uterine neoplasm currently.
