Objective To study the clinical features,pathological characteristics and prognosis of renal cell carcinoma(RCC)in young adults,and to improve the recognition of RCC in young population. Methods The data of 35 young patients with RCC under the age of 35 years from August 1983 to June 2005 were analyzed retrospectively.There were 22 males and 13 females with a mean age of 31 years(age range, 19-35 years).The clinical presentations were as follows:painless hematuria in 12 cases(34%),low back pain in 12(34%),abdominal mass in 2(6%),fever in 3 and Stauffer syndrome in 1.The tumor size was 1.2-13.8 cm in diameter(mean,6.0cm).AJCC staging showed stage I tumor in 8 cases,stageⅡin 4, stageⅢin 18 and stageⅣin 5.Of the 35 cases,28 underwent radical nephrectomy(including simultaneous extraction of the vena cava emboli in 3 cases and extraction with pulmonary lobectomy in 1);5 cases under- went partial nephrectomy;and 2 cases lost the chance of operation(1 of them had biopsy).Results The operations were successful.The postoperative pathologic diagnoses consisted of clear cell carcinoma in 23 ca- ses,mixed cell carcinoma in 5,papillary cell carcinoma in 2,and chromophobe cell carcinoma in 2,low-dif- ferentiated and undifferentiated cell carcinoma each in 1.Of them,26 cases were followed for 12-148 months(mean,56 months).Postoperative 3-and 5-year survival rates were 65% and 50%,respectively. Conclnsions In young population,RCC is difficult to diagnose because of occult symptoms at early stage and lack of tumor specificity,which leads to relatively late clinical staging at diagnosis.RCC is characterized by higher malignancy,easy invasion to surrounding tissues and metastasis,and thus poor prognosis.

Although talus fractures are not common among foot and ankle injuries, their treatment is difficult because of their complications and poor prognosis. They can be treated conservatively or surgically, with a variety of treatment protocols. At present, the main strategy of surgical treatment is to use strong and effective fixation to restore anatomic structure of the talus and preserve blood supply to the talus as much as possible so that deformity can be avoided and early healing be facilitated. This paper reviews the difficulties and current situation, and summarizes principles and the latest progress in clinical treatment of talus fractures, hoping to provide useful references for the treatment.

Objective To investigate the effect of dihydromyricetin on proliferation and apoptosis of breast cancer MCF-7 cells.Methods From March 2014 to February 2015,breast cancer MCF-7 cells were treated with 99% pure DMY as an inhibitor.MTT assay,flow cytometry and immunocytochemistry were used to analyze the proliferation,apoptosis and protein expression of breast cancer cell MCF-7.Results When the DMY concentration was higher than 20 μg/mL,the inhibitory effect appeared,but not good.When 40 and 80 μg/mL DMY were used,the proliferation of MCF-6 cells were significantly inhibited,and have different degrees of sensitivity to it.When DMY was 80 μg/mL,the IC50 was 226.9 μg/mL.The inhibition rate and IC50 were compared with 0 μg/mL DMY,there was significant difference(P<0.05).Indicating that the relatively high concentration of DMY could significantly improve the patient′s condition of breast cancer;MCF-6 cells treated with 40 and 80 μg/mL DMY could induce G2/M phase arrest in DMY with concentration greater than 20 μg/mL(P<0.01),and showed significant cell apoptosis death phenomenon.At the same time,G0/G1 phase was also blocked and S phase cells decreased significantly,the difference was significant(P<0.05).The positive rate of PCNA in breast cancer MCF-6 cells significantly decreased(P<0.01) when the DMY concentration was higher than 50 μg/mL,the positive rate was> 50%,especially in DMY with 80 μg/mL,the positive rate was 10.00%.Compared with 0 μg/mL DMY,the difference was significant(P<0.05).Conclusion The use of dihydromyricetin in breast cancer patients can effectively inhibit the rapid increase of cancer cells,accelerate apoptosis,slow down the patient′s condition,the effect is outstanding.

Objective The study evaluated the efficiency and safety of a short-acting full-dose fibfinolytic regimen to promote early infarct-related artery (IRA) patency during the inherent delay experienced by infarction patients referred for angioplasty as the principal recanalization modality. Method Accepted aspirin and heparin, 75 patients were treated by an intravenous bolus of 20 mg recombined tissue-type plasminogen activator (rt-PA), then followed by 80 mg over 30 minutes. Patients were to undergo angiography as soon as possible following study drug. If the IRA was occlude (TIMI flow grade 0 or 1),or was open but with ≥50% stenosis, immediate early PTCA at the same time. The end point included patency rates on catheterzation laboratory (cath Lab) arrival, technical results when PTCA was performed, complication rates, clinical adverse events rates and left ventricular (LV) function by treatment assignment in two weeks. Results Patency on Cath lab arrival was 88% with combination treatment group (26% Thrombolysis in myocardia infarction trial TIMI-2, 66%TIMI-3), and 36%with primary PTCA group (20%TIMI-2, 16%TIMI-3), (P

Aim to explore the adverse drug reactions (ADR) characteristic and calculate the ADR incidence of Dengzhan Xixin injection (DZXX). A multicenter, large sample, and prospective cohort study was conducted from August 2012 to December 2014. A total of 31 724 patients using DZXX were observed. A total of 31 724 patients with 15 ADR cases among 31 724 patients, accounting for 0.06% , were reported. There were 8 male patients ADRs and 7 female patients with ADRs. ADRs included skin rashes, itching, headache, red face, abdominal pain, etc. 1 case with rhubarb radix scutellariae allergies. These ADRs happened from 5 min to within 0.5 h after DZXX were used to treat patients. ADR patients discontinued treatment, of which 2 patients used promethazine for recovery and improvement. There were 2 cases with different DZXX concentration, out of the normal range. DZXX injection could cause some ADRs. Users must not ignore these and be careful of its related side effects. This study was a cohort with large sample, which should produce strong evidence for clinical practice. However, there was still weak evidence to conclude that it was a safe Chinese medicine injection in clinical practice.

In order to promote the Shenqifuzheng injection (SQFZ) clinical medication safety, this study reevaluate on SQFZ post marketing safety study systematically. Including multi center large sample registration type safety monitoring research, the analysis based on national spontaneous reporting system data, the analysis based on the 20 national hospital information system data and literature research. Above the analysis, it suggests that SQFZ has good security. The more adverse drug reaction (ADR) as allergic reactions, mainly involved in the damage of skin, appendages and its systemic damage, serious person can appear allergic shock. ADR/E is more common in the elderly, may be related to medication (tumor) populations. Early warning analysis based on SRS data and literature research are of the view that "phlebitis" has a strong association with SQFZ used.

Objective To investigate the effect of plasma exchange (PE) in the treatment of chronic severe hepatitis. Methods 70 cases with chronic severe hepatitis were divided randomly into two groups:treatment group and control group. The treatment group combined with PE based on combined therapy of internal medicine, control group was only performed combined therapy of internal medicine. The therapeutic efficient rate was analyzed by con-trast after one month. Results The level of TBil,ALT,CHO,CHE,PTA,BUN and Cr of patients in treatment group improved more obviously than those in control group(P <0.05). The total effective rate was 62.86% in treatment group and was 31.43% in control group,and there were significant differences in two groups(P <0.05). The death rate was 11.42% in treatment group and was 31.42% in control group,there were significant differences in two groups (P < 0.05). Conclusion PE combined with therapy of internal medicine can obviously improve therapeutic efficient rate of chronic severe hepatitis,which is an safe and effective method.

The paper is to report the pharmacokinetics of sulfamethoxazole in healthy Han volunteers living at plain (PH) and native Han and Tibetan healthy volunteers living at high altitude (HNH and HNT). After healthy volunteers were administrated orally cotrimoxazole tablets, plasma concentration of sulfamethoxazole and metabolite N4-acetylsulfamethoxazole was determined by RP-HPLC, and plasma concentration-time data were analyzed by DAS 2.0 software to get the related pharmacokinetic parameters. The main pharmacokinetic parameters t(1/2) of sulfamethoxazole in PH, HNH and HNT were, respectively, 9.30 +/- 1.11, 10.99 +/- 1.23 and 10.44 +/- 1.05 h; tmax were 1.4 +/- 0.3, 2.0 +/- 1.1 and 1.8 +/- 0.4 h; Cmax were 94.42 +/- 15.26, 89.33 +/- 7.67 and 87.43 +/- 11.61 micro x mL(-1); AUC(0-t) were 1202.5 +/- 238.3, 1 434.7 +/- 193.9 and 1302.8 +/- 103.0 microg x h x mL(-1); AUC(0-infinity) were 1240.7 +/- 255.3, 1511.5 +/- 211.9 and 1363.9 +/- 116.5 microg x h x mL(-1); CL were 1.01 +/- 0.22, 0.81 +/- 0.12 and 0.89 +/- 0.08 L x h(-1) x kg(-1); V were 13.27 +/- 1.73, 12.81 +/- 2.15 and 13.28 +/- 1.20 L x kg(-1). Sulfamethoxazole pharmacokinetic parameters of HNH and HNT were significantly different from that of PH. The t(1/2) was significantly higher and the CL was significantly lower in HNH and HNT than that in PH, and the AUC(0-infinity) was significantly lower in HNT compared with HNH. This study found significant changes in the disposition of sulfamethoxazole under the special environment of high altitude hypoxia. This finding may provide some references for clinical rational application of sulfamethoxazole in HNH and HNT.

AIM:To perform a new method for orbital implant and contracted socket through one time and its results. ·METHODS:Totally 114 patients 114 eyes, from January 2008 to June 2014, with contracted socket participated in this study. We incised the bulbar conjunctiva horizontally and excised scar tissue, then implanted the hydroxyapatite in the four extraocular muscles and tightly sutured the Tenon ' capsule. After that, we put the superior and inferior conjunctival petals backwards and sutured them to the Tenon ' s capsule. All the patients were divided into four groups according to the vertical diameter length of the conjunctival defect area:GroupⅠ:≤5mm; Group Ⅱ: 6-10mm; Group Ⅲ: 11-15mm; and Group Ⅳ: ≥16mm. These patients were followed up for 6mo to 3y to observe the conjunctival sac shaping and growth of conjunctiva. ·RESULTS:There were 64 cases in GroupⅠ, 31 cases in Group Ⅱ, 16 cases in Group Ⅲ and 3 cases in Group Ⅳ. All patients ' conjunctival defect was covered by new conjunctiva and scar tissue 4 to 6wk after surgeries. Ten cases had contracted socket; 2 cases had orbital implant exposure, requiring reoperation. Of the 114 cases, 8 had contracted socket and could use a smaller conformer, 106 could use a normal size conformer. ·CONCLUSION: When the conjunctival defect was ≤15mm, this new method can address the orbital implant and contracted socket at the same time. While it was ≥16mm, flap transplantation is necessary.
