Objective To assess the effectiveness of uterine arterial embolization for the treatment of hysteromyomas and to discuss the factors related to the clinical results.Methods Super-selective uterine arterial embolization was performed in forty-five patients with hysteromyomas.Of 45 patients,multiple hysteromyomas were seen in 36 and solitary lesion in 9.The lesion was located at the myometrium in 41 cases,among them coexisted endometrioma was found in 5 cases and coexisted submucosal myoma in 2.The lesion was located submucous layer in the remaining 4 cases.The diagnosis was confirmed by imaging study and gynecological examination.After the operation,ultrasonography and laboratory tests were carried out in all patients to observe the tumor size.hormone levels and hemoglobin concentration.Results A total of 91 uterine arteries were found in 45 patients.including double left uterine arteries in one case.Successful catheterization was obtained in 87 arteries(95.6%).All forty-five patients were followed up for 6-36 months.Six months after the procedure the mean reduction of the tumor size was 69.3%.and the lesion completely disappeared in two cases.In the anemic patients the hemoglobin concentration returned to normal level.The main side-effects included low fever and pain at lower abdomen.Conclusion Uterine arterial embolization is a safe and effective treatment for hysteromyomas.

A 48-year-old man presented with a 4-day history of fever and 10-year history of papulovesicles on the face, neck, trunk and limbs which had been aggravated 10 days prior to the presentation.Skin biopsy showed a dermal infiltration of numerous small- to medium-sized atypical lymphocytes, which was mainly located around blood vessels or appendages, with the involvement of subcutaneous fat tissue and destruction of blood vessels. The infiltrating atypical cells stained positive for CD45RO, CD8, CD56, T-cell intracellular antigen-1, granzyme B, Epstein-Barr virus-encoded small nuclear RNAs (EBER), but negative for CD20, CD79a, CD3, CD4 or CD30. Cytoplasmic CD3ε was also observed in these cells. Laboratory examinations on admission revealed a progressive decrease in peripheral erythrocytes, white cells and platelets, persistent increase in serum aminotransferase and bilirubin, and decline in serum fibrinogen and hypertriglyceridemia. The B-mode ultrasound of the abdomen showed hepatosplenomegaly. Based on the above findings,the diagnosis was made as extranodal nasal type NK/T-cell lymphoma of skin complicated by hemophagocytic syndrome.

Objective To evaluate short-term curative effect of endovascular abdominal aortic aneurysm repair. Methods Twelve cases of infra-renal abdominal aortic aneurysms were checked. Results The av-erage bleeding in the operation was 245 millimeter, the avenage hospitalization time was 8.6 days, and the average abrosia time was 1.5 days. White blood cell, hemoglobin, thrombocyte, hepatic function, and renal function were in the normal limits. Prothrombin time and activated partial thromboplastin time were post-poned after operation, and recovered normally within one week. Complications of operations were as follows:1 case of pulmonary infection, 2 cases of abdominal distention, and 1 case of intraoperafive endoleak. The former two kinds of complications alleviated after conventional treatment, and the latter disappeared naturally after 3 months. Conclusion Endovascular abdominal aortic aneurysm repair is safe, mini-invasive, and has little disturbance for body internal environment.

Objective To explore the efficacy and tolerability of sorafenib in combination with interferon-α-2b for Chinese patients with metastatic renal cell carcinoma. Methods Seventeen pa-tients with unreseetable metastatic renal cell carcinoma were enrolled and received sorafenib in combi-nation with interferon-α-2b. Sorafenib was continuously given at the dose of 400 mg twice per day, in-terferon-α-2b 300 MIU subscutaneously once per day for 5 d each week, until disease progression or intolerable toxieities occurred. Tumor responses were evaluated every two months by response evalua-tion criteria in solid tumor. Results The median treatment duration was 120(51-442)d. All 17 pa-tients were evaluable for efficacy and safety. Five patients achieved partial responses (PR), 1 uncon-firmed PR,9 stable diseases. Two patients had progressed diseases. The overall response rate was 29%(5/17)with the disease control rate of 88%(15/17). Due to short-time follow up, the median progression free and overall survival time were not yet available. The common side effects included: fever 82%(14/17), diarrhea 82%(14/17), hand-foot syndrome 71%(12/17), asthenia 65%(11/17), rash 53%(9/17), alopecia 41% (7/17), mucosities 41% (7/17), hypertension 29% (5/17), anorexia 24% (4/17), hoarseness 24% (4/17), myalgia 24 % (4/17), nausea/vomiting 12 % (2/17) and headach/ dizzle 12%(2/17). Eleven (65%) out of 17 patients developed neutropenia, 5(29%) thrombocytope-nia and 5 (29%)anemia. Four(24%) out of 17 patients had abnormally elevated ALT/AST. Conclu-sion Sorafenib in combination with interferon-α-2b for metastatic renal cell carcinoma improves re-sponse rate with manageable toxicity.

Objective To evaluate the clinical outcome of external bracket fixation in the treat- ment of complex tibia diaphysis fracture involving intra-articular fractures.Methods Forty-two cases of complex tibia diaphysis fracture with proximal and distal intra-articular fractures treated surgically in our hospital from January 1999 to January 2004 were analyzed.The complex tibia diaphysis fractures were categorized according to the AO classification as type C2 (multiple segments fracture) and type C3 (ir- regular fracture),proximal and distal intra-articular fractures in 23 and 19 cases,respectively.Definite operation was done within one week.Twenty-two cases were treated with simple external fixator,and 20 cases treated with screws and external fixator.Results All the 42 cases were followed-up regularly. According to AO evaluation of the knee and ankle joint movement,83% (35/42 cases) of the cases gained satisfactory functional outcome,14% (6/42 cases) had quite satisfactory results and 2% (1/42 case) had unsatisfactory functional outcome.Conclusion External bracket fixation can obtain outcome of relative length of the tibia and fibula,tube structure reconstruction,smoothness of the articular surface and the parallel and symmetric relation of knees and ankles for complex tibia diaphysis fracture with proxi- mal and distal intra-articular fracture.The arthritis resulting in pain in movement and restriction of func- tion is considered to be the most important factor affecting the joint function.Early functional exercise is important for best recovery of knee and ankle function.

Objective To investigate the feasibility and clinical effect of the tubeless minipercutaneous nephrolithotomy (PCNL) in treatment of upper ureteral calculi.Methods From March 2014 to March 2015,all the patients with upper ureteral calculi except for those with severe infection,pyonephrosis or renal cortex less than 5 mm were randomized into two groups,the standard PCNL group (24 F nephrostomy tube) and the mini-PCNL group (18 F nephrostomy tube).After PCNL,all the patients received ultrasound examination to check residual stones,perforation and urine leakage.DJ tube was placed and the channel of PCNL was packed with hemostatic sponge without nephrostomy tube.There were 26 patients in standard group and 28 in mini-group.The operation time,postoperative hemoglobin change,postoperative visual analogue pain score (VAS),the time when urine turned clean,postoperative urinary extravasation,hydrothorax,fever and the stone-free rate were compared between two groups.Particularly,these data were compared in those aged＞65 years.Results The operation time in the standard PCNL and the mini-PCNL group was (58.3 ±21.8) and (86.4±23.3) minutes respectively,and had a significant difference (t=10.836,P＜0.05).The decrease in hemoglobin level was (8.3±5.8) g/L and (7.7±0.5.4) g/L,the VAS scores was (3.8±0.8) and (3.6±1.1),the time when urine turned clean was (11.9±4.7) h and (9.6±5.6) h,the postoperative hospital stay was (5.1±0.8) d and (4.8±1.2) d,and the stone free rate was 92.3％ and 89.2％ in standard PCNL and mini-PCNL group respectively(P＞ 0.05).No significant difference were found between two groups (all P＞0.05).There was one patient who got fever more than 38.5℃ in the standard group and 2 cases in the mini-group.Each group had 1 slight hydrothorax,and no blood infusion and perinephric urinary extravasation were found.The application of packing hemostatic sponge in the nephrostomy channel was feasible and suitable for both the standard and tubeless mini-PCNL groups.Conclusions The application of packing hemostatic sponge in the nephrostomy channel is feasible and suitable in both the standard and tubeless miniPCNL.It is safe for the treatment of renal and ureteral calculi,and it can decrease the hemorrhage and urine leakage,which works for the elderly patients too.

Objective To further clarify the pathogenesis of different types of Kaposi′s sarcoma (KS) by measuring the protein expressions of caspase-3 and E-cad in tumor tissues of Xinjiang Uygur patients with acqured immunodeficiency syndrome (AIDS)-Kaposi′s sarcoma (KS) and classical KS.Methods From July 2011 to October 2014, 38 patients with KS at the First Affiliated Hospital of Xinjiang Medical University and Urumqi Infectious Disease Hospital were enrolled, among whom 28 were male and 10 were female, and all of them were uygur.Immunohistochemical and Western blot methods were used to detect the expressions of caspase-3 and E-cad proteins in 22 cases of AIDS-KS patients and 16 cases of classic KS.The quantitative data of normal distribution were analyzed by t test, while count data were compared with χ2 test with R × C table.Results KS lesions in patients with classic KS were confined to the skin, without mucosal, lymph node or visceral involvement.Lesions in AIDS-KS patients were not only confined to the skin and superficial lymph nodes, but also oral mucosa involved in 12 cases and internal organs involved in 7 cases.Liver and lung involvement was more common.The CD4+T lymphocyte count in patients with AIDS-KS was (200.8±166)/μL.All 15 AIDS cases with CD4+ T cell count less than 200/μL developed opportunistic infections.CD4+ T lymphocyte count of patients with classic KS was (562.52±222.66)/μL and the 16 patients with CD4+T lymphocyte count greater than 350/μL had no opportunistic infections.The results of immunohistochemistry showed that the positive expression rate of caspase-3 protein in KS tissues in patients with AIDS-KS was 68.2%, in patients with classic KS was 100.0%, with significant difference between two groups (χ2=7.37, P=0.01).The positive expression rate of E-cad protein in KS tissues in patients with AIDS-KS was 72.7%, in patients with classic KS was 100.0%, with significant difference between two groups (χ2=5.18, P=0.03).Western blotting showed that the gray value of caspase-3 in the KS tissue of patients with AIDS-KS was 0.55±0.36, and that in patients with classic KS was 0.86±0.56, with significant difference between two groups (t=-2.070, P<0.05).The gray value of E-cad in the KS tissue of patients with AIDS-KS was 0.54±0.41, and that in patients with classic KS was 0.85±0.45, with significant difference between two groups (t=-2.060,P<0.05).Conclusions There are differences in the protein expressions of caspase-3 and E-cad in tumor tissues of patients with AIDS-KS and classical KS in Xinjiang Uygur patients with Kaposi's sarcoma, which may correlate with a faster progression and a higher mortality rate for AIDS-KS.

Objective To develop an early-warning indicator system of brucellosis outbreak. Methods The methods of literature review and expert discussion were used to formulate the initiatory framework and indicators, and then Delphi method was used to filter indicators, discuss the boundary of indicators and determine the weighting coefficient. Results The average length of service provided by experts who engaged in prevention and control of brucellosis was (25.10 ± 8.80) years and the positive coefficient of the consultant experts of the two-round results were 95% and 68%, respectively. Kendall coefficients were 0.35, 0.54 and X2R value were 81.31 and 285.27, respectively and P value was all less than 0.01. Five first-level indicators(the host animal, high-risk groups,social environment, index case and the level of previous disease) and 13 secondary indicators were selected to develop the early-warning indicator system of brucellosis outbreak. The weight coefficients of the five first-level indicators were 0.21, 0.22, 0.17, 0.21 and 0.19, respectively. Conclusions The early-waming indicator system of brucellosis outbreak is initially established. We propose to develop the early-warning programs according to local conditions and the indicator system.

Objective To assess the curative effect of percutem transilluminated with negative pressured on the potaried technique on the treatment of venous ulcer in lower extremity.Methods The clinical date of 300 cases involving 300 legs with venous ulcer in lower extremity,who underwent the percutum transilluminated negative pressured potaried technique using TRIVEXTM Ⅱ potaried system or the percutum transfixion surgical treatment from October 2005 to June 2009,were analyzed.Three hundred cases were randomly divided into potaried group and transfixion group.In potaried group,there were 190 cases involving 190 legs treated with TRIVEXTM Ⅱ potaried system.In transfixion group,110 cases involving 110 legs treated with percutum transfixion.The clinical indexes of skin infection rate and skin necrosis rate,shrinkage rate of wound area and skin depigmentation rate,ulcer healing rate and ulcer recurrence rate were calculated to assess the clinical curative effect on day 5,day 20,day 120 and day 360 after operation respectively.Results The rates of skin infection and skin necrosis were significantly decreased in potaried group compared with transfixion group on day 5 after operation (P0.05).Ulcer recurrence rate was remarkably lower in potaried group than that in transfixion group on day 360 (P

OBJECTIVETo investigate the effects of ischemic postconditioning (IPostC) on pneumocyte apoptosis after lung ischemia/reperfusion injury in rats.

METHODSAdult male SD rats were randomly divided into 3 groups based upon the intervention (n = 8): control group (C), lung ischemic reperfusion group (LIR), LIR+ IPostC group (IPostC). At the end of the experiment, blood specimens drawn from the arteria carotis were tested for the content of malondialdehyde (MDA), the activity of superoxide dismutase (SOD) and myeloperoxidase (MPO); the pneumocyte apoptosis index (AI) was achieved by tennrminal deoxynucleotidyl transferase mediated dUTP nick end abeling (TUNEL); the expression of Bcl-2, Bax protein in lung tissue was accessed by quantitative immunohistochemistry (MHC) and Bcl-2, Bax mRNA by RT-PCR.

RESULTSIPostC could significantly attenuate the MDA level, MPO activity and improve SOD activity in blood serum which was comparable to I/R and significantly reduced the number of TUNEL-positive cells compared with I/R group, expressed as Al (% total nuclei) from (39.0 +/- 3.46) to (8.0 +/- 0.88) (P < 0.01). The protein and mRNA expression of Bcl-2 and Bax showed that IPO significantly attenuated the ischemia/reperfusion-upregulated expression of Bax protein but improved the expression of Bcl-2 that improved the Bcl-2/Bax ratio (P < 0.01) .

CONCLUSIONIPostC may attenuate pneumocyte apoptosis in LIRI by up-regulating expression of Bcl-2/Bax ratio and by inhibiting oxidant generation and neutrophils filtration.
