Objective To evaluate the efficacy and safety of sunitinib versus sorafenib in the first-line treatment of advanced renal cell carcinoma.Methods Forty-two patients with advanced renal cell carcinoma were divided into two groups according to the therapeutic method.Twenty patients were treated with sunitinib (50 mg, oral administration, once a day, for 4 weeks, drug withdrawal of 2 weeks, 6 weeks was a cycle) and 22 patients were treated with sorafenib (400 mg, oral administration, twice a day, until the disease progression, 6 weeks was a cycle).The efficacy and toxicity were evaluated every 2-cycle treatment.Results All 42 patients could be evaluated.The disease remission rate (RR), disease control rate (DCR) of sunitinib group and sorafenib group were 30.0％ (6/20), 22.7％ (5/22), 90.0％ (18/20), 77.3％ (17/22) respectively,the median progression free survival (PFS) were 10.8, 6.2 months, the median overall survival (OS) were 25.6, 18.6 months respectively.There were no statistical differences in the RR (x2 =0.287, P =0.592) and DCR (x2 =1.222, P =0.269) between the two groups.There were statistical difference in the PFS (x2 =6.041, P =0.014) and OS (x2 =11.245, P =0.001) between the two groups.The most common toxicities of the sunitinib group were diarrhea, fatigue, oral mucositis, nausea, vomiting, all these toxicities were mainly Ⅰ-Ⅱ degree, and could be well tolerated.The hand-foot syndrome rate of the sorafenib group obviously exceeded the sunitinib group (59.1％ vs.25.0％ , x2 =4.972, P =0.026).Conclusion Sunitinib has good efficacy in the first-line treatment of advanced renal cell carcinoma with less toxicity than sorafenib, so it is worthy of popularization.

Objective:To investigate the differentially expressed miRNAs in serum collected post operation and compared these miR-NAs with those collected pre-surgery among patients suffering from glioblastoma multiform (GBM) and undergoing regular clinical fol-low-up. These miRNAs may be potential biomarkers for the post-operative evaluation of patients with GBM. Methods:Forty-eight pa-tients with GBM and clinical pathological diagnosis were enrolled in this study. In the initial biomarker screening stage, total RNAs were extracted and subjected to Solexa sequencing to select miRNAs with significantly altered expression pre-and post-operation. Some of these differentially expressed miRNAs were chosen and verified through TaqMan probe-based qRT-PCR assay. A t-test was performed to determine the miRNAs that satisfied the two criteria, namely, fold change>2 and P<0.05. All of the patients were fol-lowed-up, and survival data were collected. The patients were then classified into two groups, namely, long-and short-survival groups, on the basis of the median of the miR-30e expression levels in the sera collected post-operation. Kaplan-Meier method and Log-rank test (SPSS version 19.0, IBM) were employed to determine the possible relationships between miR-30e expression levels in the sera collected post-operation and patients' overall survival. Results: Solexa revealed 63 differentially expressed miRNAs. Four miRNAs, namely, miR-26b, miR-30e, miR-129-3p, and miR-206, were selected on the basis of previous and present findings. These miRNAs were then verified in the RT-qPCR phase. Among these miRNAs, only miR-30e was significantly upregulated post-operation. The serum miR-30e expression level post-operation was not significantly associated with the overall survival of the patients. A low miR-30e expression level corresponded to prolonged survival. Conclusion:miR-30e was upregulated in the sera collected post-operation from patients with GBM. This miRNA may be negatively related to the tumor load of these patients. The miR-30e expression level in the serum col-lected post-surgery serum was not significantly associated with overall survival. Therefore, miR-30e may serve as a novel potential non-invasive biomarker for the post-operative evaluation of patients with GBM.

Objective:To analyze the relationship between free androgen index and insulin function in obese young men aged from 20 to 35.Methods:A total of 82 young obese men in Obesity Clinic from February to October 2019 were enrolled in the study. The subjects were divided into 3 subgroups according to free androgen index level tertiles. The blood glucose and insulin levels were tested after oral glucose tolerance test. Homeostasis model assessment for insulin resistance (HOMA-IR), homeostasis model assessment for β cell function (HOMA-β), insulin secretion index, and insulin sensitivity index (Matsuda index) were used to evaluate β cell function in oder to analyze the relationship between free androgen index and insulin function.Results:In young obese men, participants with higher free androgen index levels exhibited less waist circumference, lower body mass index, 1 h postprandial insulin, 2 h postprandial insulin, HOMA-IR level but with a higher total testosterone, sex hormone binding globulin, and Matsuda index level (all P<0.05). There was a negative correlation between the free androgen index and the HOMA-IR ( r=-0.386, P=0.016), and the correlation tended to a linear trend after adjustment for age, sex, body mass index, and waist circumference ( Ptrend=0.034). Free testosterone was positively correlated with Matsuda index ( r=0.280, P=0.004), but the correlation disappeared after adjustment ( Ptrend=0.623). The results of further regression analysis showed that the level of free testosterone index decreased by 14.1% ( OR=0.869, 95% CI0.767-0.984, P=0.028) for each increase of HOMA-IR after adjustment. Conclusion:The level of free testosterone index is a predictor of insulin resistance in obese young men, but the association between this parameter and insulin sensitivity may be caused by obesity.

ObjectiveTo investigate the misdiagnostic reason and treatment of the syndrom of splenic flexure of colon(SSFC). MethodsThe clonical data of 21 patients with SSFC admitted from May 1993 to May 2001 were retrospectively analysed. ResultsThese patients aged from 51 to 88 years old with a median age of 67.8years.Clinical manifestalion was repetitive stomach pain, abdominal distension, constipation, etc. Double contrast radiology of colon demonstrated that too high fixation site of colon of splenic flexure, volvulus of colon of splenic flexure, and displacement of colon usually occurred together with transverse or sigmoid colon redundant.All of them were cured by cololysis of colon of splenic flexure, redundant partial colectomy and managing other companying diseases.Postoperative pathological diagnoses were chronic colitis.Followed up was done for 6 months to 6 years, all of them released from primary symptoms. ConclusionsThe main misdiagnostic reason of SSFC is less understanding of SSFC and did not take double contrast radiology of colon. By way of cololysis of splenic flexure, redundant colon resection and managment other companying abdominal diseases, most patients with SSFC may expect satisfactory treatment effects.

Objective To evaluate the effects of ulinastatin on hemorrhagic shock and resuscitation ( HS∕R)?induced acute lung injury in rats. Methods Fifteen SPF adult Sprague?Dawley rats, aged 2-3 months, weighing 300-400 g, were divided into 3 groups ( n=5 each) using a random number table:sham operation group ( group S ) , HS∕R group and ulinastatin group ( group U ) . Carotid arteries were cannulated for blood pressure monitoring and blood?letting. HS∕R was induced by blood?letting and maintained for 1 h, followed by resuscitation with autologous blood transfusion and infusion of normal saline. After cannulation of carotid arteries ( T0 ) , at 5 min after hemorrhagic shock ( T1 ) , before resuscitation ( T2 ) , at 5 min after the expected blood pressure was achieved following resuscitation ( T3 ) , and at 30 min, 1?5 h and 2?5 h after resuscitation ( T4?6 ) , arterial blood samples were collected for determination of interleukin?6 ( IL?6 ) and tumor necrosis factor?α ( TNF?α) concentrations ( by enzyme?linked immunosorbent assay) . Arterial blood samples were collected at T0 , T2 and T6 for blood gas analysis. The pH value, partial pressure of arterial carbon dioxide ( PaCO2 ) , HCO-3 and base excess ( BE) value were recorded, and oxygenation index ( PaO2∕FiO2 ) was calculated. Lungs were removed at T6 , and pulmonary specimens were obtained for examination of pathological changes which were scored, and nucleus was extracted for determination of nuclear factor?kappa B ( NF?κB ) p65 expression by enzyme?linked immunosorbent assay. Results Compared with group S, the pH values, HCO-3 , BE values and OI were significantly decreased, and PaCO2 , plasma IL?6 and TNF?α concentrations, expression of NF?κB p65 in lung tissues, and pathological scores were increased in U and HS∕R groups. Compared with group HS∕R, the plasma concentrations of IL?6 and TNF?α, expression of NF?κB p65 in lung tissues, and pathological scores were significantly decreased, and no significant changes were found in parameters of blood gas analysis in group U. Conclusion Although ulinastatin can alleviate HS∕R?induced acute lung injury, it is insufficient to improve lung oxygenation in rats.

BACKGROUNDThe hemodynamics and oxygenation severely fluctuated during the off-pump coronary artery bypass grafting (OPCABG). This study aimed at investigating whether or not nicardipine combined with esmolol (1:10) can maintain systemic and tissue oxygenation during OPCABG.

METHODSTwenty patients scheduled for OPCABG were divided ramdomly into Group nicardipine (N) and Group nitroglycerine (X) respectively combined with esmolol (E) (Dosage ratio: 1 to 10) (Group N + E and Group X + E) with 10 patients in each group. The mixed solution of N + E or X + E were titrated to maintain mean arterial blood pressure between 70 and 80 mmHg following anesthesia induction. The variables of hemodynamics, arterial blood lactate content (Lac) and gastric intramucosal partial pressure of carbon dioxide were measured at the following time points: after induction of anesthesia (T1), pre-revascularization (T2), grafting of left anterior descending (T3), right coronary descending (T4) and left coronary circumflexus branches (T5), post-revascularization (T6), the end of operation (T7). The delivery of oxygen (DO2), consumption of oxygen (VO2) and gastric intramucosal pH (pHi) were calculated.

RESULTSThe cardiac index (CI) in Group N + E was significantly increased (P < 0.05) as compared with T1 during OPCABG, while it was mildly decreased in Group X + E. The stroke volumes at T4, T5 in Group N + E and at T3-T6 in Group X + E were significantly decreased (P < 0.05). The systemic vascular resistance indices in Group N + E were significantly decreased as compared with T1 (P < 0.05). The heart rates in these two Groups were significantly elevated intraoperatively (P < 0.05). The DO2 after the infusion of N + E was significantly increased (P < 0.05) or leveled to T1, and the Lac were within the normal range. But the DO2 in Group X + E was decreased throughout the procedure, reaching significant level at T5 (P < 0.05), and the Lac was significantly increased beyond normal range (P < 0.05). The pHi in Group N + E was maintained above 7.35 during OPCABG, while it was less than 7.35 from T4 to T7 in Group X + E.

CONCLUSIONNicardipine combined with esmolol (1:10) regimen may maintain systemic and tissue oxygenation during OPCABG.

OBJECTIVETo evaluate the analgesic efficacy and systemic anti-inflammation of preoperative cyclooxygenase-2 nonsteroidal antiinflammatory drug, rofecoxib, after total knee replacement (TKR).

METHODSThirty patients underwent elective knee replacement were randomly given oral rofecoxib 25 mg (group RE, n = 15) or placebo (group E, n = 15) 1 hour prior to surgery. All patients received epidural combined isoflurane anesthesia during surgery and patient-controlled epidural analgesia after surgery for 72 hrs (0.1 mg/ml morphine + 1.2 mg/ml bupivacaine + 0.02 mg/ml droperidol). Modified verbal rate scale was used to evaluate postoperative pain intensity. The outcomes included pain scores during rest and movement of knee joints and analgesia satisfaction. Daily morphine consumption was recorded. Circulation leucocyte and serum cytokine concentrations (including interleukin 6, interleukin 8, interleukin 10, Tumor necrosis factor-alpha) were determined before surgery, at the end of surgery, 2 h, 6 h, 12 h, 24 h and 48 h after surgery in two groups using RIA. The amount of intraoperative blood loss and postoperative drainage from the knees were measured.

RESULTSThe pain scores were significantly less in the group RE than in group E during rest and knee joints movement on the first and second postoperative day, with an improvement in total analgesia satisfaction (P < 0.05). The mean dose of morphine for first 24 h was (8.1 +/- 1.5) mg in the E group and (6.8 +/- 0.7) mg in the RE group (t = -2.71, P < 0.01). Leucocyte and neutrophil counts were much higher in group E than in group RE at 12 h, 24 h post-operatively (P < 0.05). Serum TNF-alpha concentration was significantly lower in group RE than group E at the end of surgery, 6 h, 12 h postoperatively, as well as IL6 at 48 h, IL8 at 24h after surgery (P < 0.05). There were no significant differences in respect to the amount of intraoperative and postoperative blood loss between two groups (P > 0.05).

CONCLUSIONPreoperative cyclooxygenase-2-specific nonsteroidal anti-inflammatory drug rofecoxib increases analgesia satisfaction, reduces opioid requirement and demonstrates a systemic anti-inflammatory effect after TKR.
