Objective To consider the clinical significance of retroperitoneal laparoscopic adrenalectomy for adrenal diseases. Methods We analyzed 33 cases of adrenal diseases treated by retroperitoneal laparoscopic adrenalectomy in this hospital from October 1996 to December 2001. Results Retroperitoneal laparoscopy was successfully applied in 31 cases, whereas conversions to open adrenalectomy were required in the other 2 cases. The mean operation time was 158 min (120 min～200 min). The mean intraoperative blood loss was 150 ml, without blood transfusion needed. The mean length of hospital stay was 6.4 days. Conclusions Compared with open surgery, retroperitoneal laparoscopic adrenalectomy has the advantages of minimal invasion, less blood loss, fewer complications, quicker recovery and shorter hospital stay length. This procedure can be applied to in the absence of contraindications (such as tumor size being more than 10cm, metastatic carcinoma and vital organs or blood vessels being involved).

A rapid, sensitive and convenient LC-MS/MS method was developed for the determination of γ-aminobutyric acid (GABA) in human plasma. d2-γ-Aminobutyric acid (d2-GABA) was synthesized as internal standard (IS). After extraction from human plasma by protein precipitation with acetonitrile, all analytes were separated on a Luna HILIC column (100 mm x 3.0 mm, 3 μm) using an isocratic mobile phase of water: acetonitrile: formic acid (20 : 80 : 0.12) with a flow rate of 0.5 mL x min(-1). Acquisition of mass spectrometric data was performed in multiple reaction monitoring mode (MRM) in positive electrospray ionization using the transitions of m/z 104 --> 69 for GABA and m/z 106 --> 71 for d2-GABA. The method was linear in the concentration range of 5.00 to 1 000 ng x mL(-1). The intra- and inter-day precisions were within 9.9%, and accuracy ranged from 99.1% to 104%, within the acceptable limit across all concentrations. The method was successfully applied to a pharmacokinetic study of GABA tablets in healthy Chinese volunteers.

A simple and rapid method was developed based on high performance liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) to determine sivelestat and its metabolite XW-IMP-A in human plasma. After a simple protein precipitation, the samples and internal standards were analyzed on a C18 column by a gradient elution program. The mobile phase consisted of 30% acetonitrile in methanol and 5 mmol · L(-1) ammonium acetate at a flow rate of 0.7 mL · min(-1). The mass spectrometric data was collected in multiple reaction monitoring mode (MRM) in the negative electrospray ionization. The standard curves were linear in the range of 10.0-15,000 ng · mL(-1) for sivelestat, and 2.50-1000 ng · mL(-1) for XW-IMP-A. The low limits of quantitation were identified at 10.0 and 2.50 ng · mL for sivelestat and XW-IMP-A, respectively. The intra- and inter-day precision were within 11.3% and 13.1% for sivelestat and XW-IMP-A, and accuracy was 0.3% and 0.6% for sivelestat and XW-IMP-A, within the acceptable limits across all concentrations. The method was successfully validated in the pharmacokinetic study of sivelestat in healthy Chinese volunteers.

Background and purpose:Bladder cancer radical surgery is dififcult with many perioperative complications, and the learning curve is long. To introduce the clinical application of complete retrograde radical cystectomy and consequent abdominal cavity reconstruction in male bladder cancer, and to provide a standardized surgical procedure with minimum perioperative complications and short learning curve. Methods:From Apr. 2012 to Apr. 2013, 110 cases of male patients with bladder cancer received this procedure in our department, with a median age of 64 (35-83) years;Preoperative characters, surgical parameters, perioperative complications, pathology, long-term complications and short-term prognosis were collected and analyzed. Results:The median number of lymph nodes resected in operation was 12 (8-16);Neurovascular bundles were reserved bilaterally in 65 cases, and unilaterally in 31 cases;The complete procedure including urinary diversion took 4.4 (2.2-6.0) hours, with a median time of opened abdominal cavity of 43.0 (5.0-75.0) minutes;The median blood loss was 140.0 (50.0-600.0) mL, and 4 patients needed transfusion; Median time of abdominal and pelvic drainage was 10.0 (6.0-15.0) days, the median gastrointestinal recovery time was 2.5 (1.0-12.0) days, and the median postoperative hospital stay was 17.0 (10.0-39.0) days;Grade 2 Clavien-Dindo classiifcation (CDC) of surgical complications that required medical intervention were found in 19 cases, CDC grade 3 or above were found in 8 cases;Mild to moderate postoperative ileus happened in 5 cases, all recovered in median 2 (1-4) weeks with supportive treatments;There were no perioperative deaths. All samples were sent to pathological analyses. After a median follow-up of 9 (3-15) months, no complications of or above CDC grade 3 happened, and there were no recurrence. Conclusion:Complete retrograde radical cystectomy in male bladder cancer provided clear anatomical approach, reliable neurovascular bundle preservation, less blood loss, limited abdominal organs disturbance and better surgical exposure; With respect to tumor control, more peritoneal was retained for subsequent abdominal cavity reconstruction. The introduced procedure effectively speeded up gastrointestinal recovery, reduced postoperative complications, especially the incidence of ileus and its severity, and shortened hospital stay. The learning curve of this procedure for urologists was short, and further investigation was warranted.

A simple, sensitive, selective, and reproducible liquid chromatography-tandem mass spectrometric method was developed for the simultaneous determination of repaglinide and metformin in human plasma using d5-repaglinide and d6-metformin as internal standards (ISs). After a simple protein precipitation using acetonitrile as the precipitation solvent, both analytes and ISs were separated on a Venusil ASB C 18 (150 mm x 4.6 mm, 5 microm) via gradient elution using acetonitrile--10 mmol x L(-1) ammonium acetate as the mobile phase. A chromatographic total run time of 7.5 min was achieved. Mass spectrometric detection was conducted with atmospheric pressure chemical ionization under positive-ion and multiple-reaction monitoring modes. The method was linear over the 0.2 to 60.0 ng x mL(-1) concentration range for repaglinide and over the 4 to 1 000 ng x mL(-1) range for metformin. For both analytes, the intra- and inter-accuracies and precisions were within the +/- 15% acceptable limit across all concentrations. The validated method was successfully applied to a clinical bioequivalence study.

Objective:To understand the current situation of the demand for humanistic care of schizophrenics in convalescence and analyze the influencing factors, so as to provide the basis for clinical nurses to carry out targeted humanistic care for patients.Methods:A self-produced scale with a total score of 49-245 was used to investigate 516 convalescent period schizophrenic patients in 18 tertiary mental health institutions in 13 provinces of China, single factor analysis and multiple regression analysis were performed on their influencing factors.Results:The Likert 5-point scoring method was used. The overall score of the nursing care needs of hospitalized schizophrenic patients was (202.85±35.06) points, and the average score of total items were (4.14±0.16) points. Multiple linear regression results showed female ( B=0.100, P=0.024), stable marriage ( B=-0.098, P=0.026),high school (including secondary school) Education ( B=-0.107, P=0.018), family per capita monthly income of 2 000 yuan or above ( B=0.093, P=0.043),central region ( B=-0.110, P=0.014) were the main factors that affect the demand for humanistic care of inpatients with schizophrenia in convalescence. Conclusion:The hospitalized schizophrenic patients have higher and diversified needs for humanistic care. Patients with different genders, marital status, education level, monthly family income and living area have different needs for humanistic care. Individualized and standardized nursing should be given according to the actual situation of patients' needs to provide a more supportive environment for their rehabilitation.

Background and purpose:Papillary renal cell carcinomas (PRCC) is relatively infrequent, and there are few related researches in China. This study aimed to summarize the clinical and pathological features of PRCC, and evaluate prognostic factors for patients treated with surgery.Methods:A total of 64 patients who under-went surgery for PRCC were retrospectively assessed. PRCC tissue slides from each patient were reviewed for type (ⅠorⅡ), grade, TNM stage, coagulative tumor necrosis and microvascular invasion. We estimated overall survival using the Kaplan-Meier method. Multivariate analysis was done according to the Cox proportional hazards model of factors statistically signiifcant on univariate analysis. Results:The incidence rate of ENE was 6.04%in RCC, the median age was 55 (range 22 to 78) years. The comparison of the 22 (534.4%) typeⅠPRCCs and 42 (65.6%) typeⅡPRCCs revealed that typeⅡtumors were associated with a greater stage and grade more often. The median follow-up was 46 months (range 19 to 133). Of the 64 patients, 14 died, (4.5%) with typeⅠand 13 (31.0%) with typeⅡtumors (P=0.018). The overall survival rate was 85.7%in typeⅠtumors and 55.8%in typeⅡtumors, respectively. Univariate analysis identiifed symptoms at presentation, tumor type, TNM stage and grade as prognostic factors. On multivariate analysis only metastatic RCC remained associated with decreased overall survival (HR:14.78, P=0.004). Conclusion:The per-centage of PRCC is lower and typeⅡPRCC is relatively common compared with foreign data. Metastasis at diagnosis is an independent predictive parameter of overall survival in Chinese patients with PRCC.

Background and purpose:It has been demonstrated that radical prostatectomy for patients with oligometastatic prostate cancer may contribute to improving local control of prostate cancer and overall survival by several retrospective studies. Perioperative complications play an important role in determining whether radical prostatectomy is appropriate for patients with oligometastatic prostate cancer. This study aimed to discuss the recurrence rate and the sever-ity of perioperative complications, and the primary curative effect of radical prostatectomy on oligometastatic prostate can-cer patients.Methods:A total number of 247 patients who received radical prostatectomy were recruited in the study from Jul. 2015 to Jan. 2016, including 25 patients with oligometastatic prostate cancer and 222 patients with localized prostate cancer. Patients with perioperative complications in both groups were graded with the Clavien-Dindo grading system. The proportion of PSA decline and the rates and severity of perioperative complications were analyzed in both groups.Results:The cases of prostate specific antigen (PSA) decline in the oligometastatic group were 21 (84.0%), lower than the localized group with 212 cases (95.5%). There were 6 cases (24.0%) with postoperative complications in the oligometastatic group, including serious complications (Ⅲ or above) 1 case (4.0%), and 49 cases (22.1%) with postoperative complications in the localized group, including serious complications (Ⅲ or above) 7 cases (3.2%). The differences between the groups reached no statistical significance (P>0.05).Conclusion:Radical prostatectomy for patients with oligometastatic prostate cancer could be safe, effective, and appropriate, the risk of perioperative complications should not be one of the limiting factors.

Objective To validate the Memorial Sloan-Kettering Cancer Center(MSKCC)score model and evaluate the clinical efficacy of vascular endothelial growth factor(VEGF)-targeted agents in the treatment of advanced renal cell carcinoma(RCC)in China.Methods Three hundred and forty-five patients with advanced RCC and average age of 57(17-90)years were treated with VEGF-targeted agents.There were 306 cases of clear cell RCC,20 cases of papillary RCC,4 cases of chromophobe RCC,5 cases of renal collecting duct carcinoma,3 cases of medullary carcinoma and 7 cases of unclassified RCC.The main metastatic lesions were located at lung,bone and lymph nodes.Of them,205 cases were given the treatment of sorafenib 400 mg bid without off treatment,while 140 cases received sunitinib treatment in repeated six week cycles consisting of four weeks of sunitinib 50 mg daily followed by two weeks off treatment.Overall survival(OS)was estimated by the Kaplan-Meier method.Log-rank test and Harrell concordance index analysis were used to validate the MSKCC score model.Results The median follow-up period were 23(1-68)months in the whole group.The OS was 33 months,and survival rates at 1,2,3 year were 77.6％,59.3％,46.6％,respectively.According to the MSKCC score model,the patients were segregated into three risk categories: the favorable-risk group(no prognostic factors;n =169;49.0％),in which median OS(mOS)was 46 months and 2 year OS was 75.8％;the imtermediate-risk group(one or two prognostic factors;n =150;43.5％),in which mOS was 24 months and 2 year OS was 47.7％;and the poorrisk group(three to five prognostic factors;n =26;7.5％),in which mOS was 8 months and 2 year OS was 10.1％(log-rank P ＜ 0.01).The concordance index was 0.687.Conclusions VEGF-targeted agents are effective in Chinese advanced RCC patients.The MSKCC score model can be incorporated into judging individualizing tumor prognosis and communicating about the treatment options with patients who are using VEGF-targeted agents.
