ABSTRACT
Zhachong Shisanwei Pills, composed of 13 Chinese medicinal materials, are used for treating the diseases such as hemiplegia, pain of muscles and bones, rheumatism, and joint pain. The chemical composition and pharmacodynamics of Zhachong Shisanwei Pills have not been reported. Ultra-performance liquid chromatography/quadrupole-time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS/MS) was employed to quickly identify the chemical components of Zhachong Shisanwei Pills, which was performed with Shim-pack GIST C_(18) column(4.6 mm×150 mm, 5 μm). The gradient elution was conducted with methanol-0.05% acetic acid as the mobile phase. Electrospray ionization mass spectrometry(ESI-MS) was carried out in both positive and negative ion modes. The compounds were identidied based on accurate relative molecular weight, fragment ion species, and the MS data of reference substances and in literature. In conclusion, a total of 98 compounds were identified, including 19 organic acids, 36 flavonoids, 13 volatile oils, 8 tannins, 5 2-(2-phenylethyl)chromones, 5 amino acids, 3 sesquiterpenoids, 3 alkaloids, and 2 other compounds. This study characte-rized the chemical components of Zhachong Shisanwei Pills rapidly for the first time, laying a foundation for further research on the pharmacodynamic material basis and quality evaluation.

OBJECTIVE@#To analyze how governments, hospitals and information technology(IT) companies use Internet technology to provide online health services during the early stage of corona virus disease 2019 (COVID-19) epidemic in January 2020 in China, and then provide suggestions and coping strategies for the later stage and post-epidemic time.@*METHODS@#We searched for information on ehealth services related to the outbreak of COVID-19 in China. The sources of information were mainstream search engines such as Baidu and the popular interactive social platforms such as Webchat. The keywords were "Internet+pneumonia", "Internet clinic", "pneumonia online clinic" and so on. The time of information was from January 20 to February 3, 2020. The key information was extracted and encoded by two persons back-to-back. The coding information included: name of organization provider, launching time, location of provider, service items, user, health workers engaging in the service, and so on. The coded information was entered and analyzed with SPSS 24.0 and Excel.@*RESULTS@#There were totally 57 projects launched by local governments, hospitals and IT companies. Most of them were launched from January 24th to 27th, the hospital and government projects services regionally, especially in eastern provinces. In this study, 90.48% of the enterprises and 100.00% of the hospitals had online fever clinic and consultation services for COVID-19, 66.67% of the enterprises and 37.04% of the hospitals serviced derivative health problems. Only a few projects provided tele-medical consultation. There were individual projects that provided online health management for home quarantine people. Physicians were the main force of various projects. In some hospital projects, there were also nurses, pharmacists and professional technicians to provide featured consultation.@*CONCLUSION@#Ehealth is useful and helpful for the health care system to rapidly cope with health demand during instantaneous and post epidemic time. Regional distribution of ehealth is unbalanced. There are institutional and technical feasibilities for the emergency application of Internet technology. However, community health centers seldom provide ehealth or connect with tertiary hospitals with Internet. Therefore, all kinds of providers within healthcare system should promote emergence ehealth. Tele-medical diagnosis and referral should be developed by local governments during COVID-19. The application of "Internet+medical treatment" in community medical institutions and synergy among various institutions should be promoted.

ABSTRACT
<p><b>BACKGROUND</b>Transurethral resection of the bladder tumor (TURBT) remains the gold standard for non-muscle-invasive bladder cancer (NMIBC). Laser techniques have been widely used in urology. This analysis aimed to assess the safety and efficacy of holmium resection of the bladder tumor (HoLRBT) vs. TURBT.</p><p><b>METHODS</b>A systemic search of MEDLINE, Embase, Web of Science, and The Cochrane Library as well as manual bibliography searches were performed to identify the relevant studies. The pooled estimates of operation time, obturator nerve reflex rate, bladder perforation rate, bladder irrigation rate, catheterization time, hospital stay, and one- and two-year recurrence free survivals were calculated.</p><p><b>RESULTS</b>Five studies were enrolled into our meta-analysis. No significant difference was observed in the operation time between groups (weighted mean difference (WMD) 1.01, 95% confidential interval (95% CI) -3.52 - 5.54, P = 0.66). The significant difference in the obturator nerve reflex (OR 0.05, 95% CI 0.01 - 0.04, P = 0.004), bladder perforation (OR 0.14, 95% CI 0.03 - 0.61, P = 0.009), bladder irrigation (OR 0.13, 95% CI 0.04 - 0.45, P = 0.001), catheterization time (WMD -0.96, 95% CI -1.11 to -0.82, P < 0.00001), and hospital stay (WMD -1.46, 95% CI -1.65 to -1.27, P < 0.00001) showed advantages of HoLRBT over TURBT. The 2-year recurrence free survival rate favors the HoLRBT group (OR 1.46, 95% CI 1.02 - 2.11, P = 0.04).</p><p><b>CONCLUSIONS</b>As a promising technique, HoLRBT is safe and efficient, and showed several advantages over TURBT. HoLRBT can be used as an alternative procedure for TURBT in terms of low-grade papillary urothelial carcinoma or low-grade early TNM-stage urothelial carcinoma.</p>

Ectopic Cushing’s syndrome caused by pheochromocytoma is rare. We reported a 15-year-old female patient who was admitted to hospital with typical Cushing’s syndrome. She had not started menstruation. Her plasma adrenocorticotropic hormone (ACTH) and 24-hour urinary free cortisol levels were extremely high. Gonadal and progestational hormone levels were also abnormal. Abdominal computed tomography scans and enhanced scans revealed multiple irregular tumors in the right adrenal. Pelvic echogram showed an infantile uterus, while the ovaries were at an immature stage of development. Retroperitoneal laparoscopic right adrenalectomy was performed without intraoperative complications. Histology and immunohistochemistry of the tumor were consistent with pheochromocytoma. Retroperitoneal laparoscopic adrenalectomy is a safe procedure with satisfactory outcomes and allows for rapid recovery.

<p><b>BACKGROUND</b>Although many midterm oncologic data have been reported for extraperitoneal laparoscopic radical prostatectomy (ELRP) in western countries, few oncologic data of the extraperitoneal procedure was published in China. The aim of the study was to evaluate the oncologic outcomes of patients treated with ELRP in China.</p><p><b>METHODS</b>From January 2005 to March 2010, a total of 152 consecutive patients diagnosed with clinically localized prostate cancer were included in this study and treated with ELRP. The patients were staged according to the TNM (tumor, nodes, metastases) system. Median and mean postoperative follow-up were 28.1 months and 27.0 months, respectively. The patients were retrospectively analyzed for progression-free survival.</p><p><b>RESULTS</b>One hundred and twelve cases (73.7%) were postoperatively diagnosed as pT2 in, and 40 cases (26.3%) as pT3. Positive lymph nodes were shown in 5 patients (3.3%). Gleason score was < 7 in 49 men (32.2%), 7 in 69 men (45.4%), and > 7 in 34 men (22.4%). Positive surgical margins (PSM) were observed in 15 patients (9.9%), which included 32.0% of all pT3a cases and 46.7% of all pT3b cases, respectively. The overall prostate-specific antigen recurrence-free survival rate was 86% in all patients. The recurrence-free survival rates were 91.8% and 62.2% in pT2N0 patients and pT3N0 patients, respectively. Preoperative prostate-specific antigen, surgical margins, tumor stage, and lymph nodal status were identified as independent predictors of biochemical recurrence-free survival using multivariate Cox proportional hazard model.</p><p><b>CONCLUSIONS</b>ELRP is a precise, safe and effective procedure at this particular Chinese institution. The prognostic power of prostate-specific antigen relapse after ELRP is not identical to that described previously with transperitoneal or open retropubic approaches.</p>

Objective To introduce the clinical experience and effects of retroperitoneal laparoscopic partial nephrectomy in treatment of patients with Tib renal cell carcinoma. Methods Fifteen patients (10 males and 5 females) with Tib renal cell carcinoma who were treated from Nov. 2007 to Jun. 2011 were retrospectively analyzed. The patients had a mean age of (56.2±9.8) years old and a mean tumor size of (5.5±1.4) cm in diameter, with 8 cases on the left side and 7 cases on the right side. All of the 15 patients received retroperitoneal laparoscopic partial nephrectomy. Results All the 15 cases were operated successfully without conversion to open surgery, and there were no severe perioperative complications. The mean operation time was (100±23.6) min, mean warm ischemia time (WIT) was (21.3±8.6) min, and the mean blood loss was (35.3±11.6) ml. Postoperative urinary leakage was found in one case and serum creatinine transient increase was found in one case. The mean postoperative hospital stay was (5.7±1.8) d. All patients had normal renal function and had no tumor recurrence or metastasis during a mean follow-up of (21.2±10.1) months. Conclusion Retroperitoneal laparoscopic partial nephrectomy is safe and effective for treatment of patients with Tib renal cell carcinoma, with less trauma and faster recovery; however, the long-term effects still need large sample studies and long-term follow-up.
ABSTRACT
<p><b>OBJECTIVE</b>To study the application of retroperitoneal laparoscopic partial nephrectomy in renal carcinoma patients with intermediate risk PADUA score.</p><p><b>METHODS</b>From April 2005 to June 2011, 79 cases (48 males and 31 females) of intermediate risk PADUA score (range from 8 to 9 score) renal cell carcinoma were retrospectively analyzed. Mean age was (54 ± 9) years, mean tumor size was (2.8 ± 0.8) cm in diameter, with 37 cases on the left side and 42 cases on the right side. Tumor located anteriorly in 35 cases, and 44 cases were located posteriorly. Preoperative imaging examinations showed tumor invasion of the collecting system was dislocated or infiltrated by tumor invasion were in 13 cases, renal sinus were involved in 5 cases, tumor located near the renal hilum were in 10 cases. All of the 79 patients received retroperitoneal laparoscopic partial nephrectomy.</p><p><b>RESULTS</b>The 79 cases were operated successfully without conversion to open surgery, no severe perioperative complications. The mean operation time was (105 ± 24) minutes, and the median of operation time was 115 minutes (range from 80 - 180 minutes), and mean warm ischemia time (WIT) was (20 ± 5) minutes, and mean blood loss was (24 ± 8) ml; mean postoperative hospital stay was (5.2 ± 1.5) days. Postoperative urinary leakage in 3 cases, symptoms disappeared one week after indwelling catheterization and ureteral catheter. Serum creatinine transient increased in 7 cases after surgery, and fell to normal range within 6 weeks. In a mean follow up for (34 ± 12) months (range from 10 to 84 months), estimated glomerular filtration rate (eGFR) 6 months after operation was no statistical significance compared with preoperation in 77 cases, another 2 patients' eGFR decreased by 30% and 35%. Postoperative renal function remained in CKD3 period and CKD2 period were in 2 cases respectively, none of these cases were treated with hemodialysis, and the remaining patients with normal renal function after surgery, no tumor recurrence and metastasis during follow-up in all cases.</p><p><b>CONCLUSIONS</b>Treatment of retroperitoneal laparoscopic partial nephrectomy in renal carcinoma patients with intermediate risk PADUA score is safe and effective, but its long-term effects still need to study with large samples compare and long-term follow-up.</p>

Effect of CTAB addition on the accumulation of microbial transglutaminase (MTG) with Streptomyces hygroscopicus was investigated. The results showed that the addition of CTAB enhanced MTG accumulation, and the optimal addition time and concentration of CTAB were 32 h and 1%. The maximum MTG activity in the culture broth was 5.04 u/mL and increased by 21.8% compared with the control. With the addition of CTAB, pro-MTG was activated to become MTG. CTAB could enhance the production of pro-MTG by relieving the product inhibition, and the accumulation of MTG was improved.
