Fifty-six hypertensive diabetic patients (glyeosylated hemoglobin A1c<7%)with albuminuria were randomly assigned to benazepril (10 mg/d,n=28) or amlodipine (5 mg/d,n=28) group.Blood pressure was measured at the end of 4-week treatment.Benazepril and amlodipine were increased to 20 mg/d and 10 mg/d respectively when blood pressure>130/80 mm Hg.All the patients were treated for 12 weeks.In both groups,plasma yon Willebrand factor and urine albumin decreased significantly from baseline.Except for urine albumin,no significant inter-group difference in plasma van Willebrand factor and target blood pressure was observed.Benazepril and amledipine seem to show similar efficacy in lowering blood pressure and improving endothelial function,but benazepril may be more effective in kidney protection.

Objective To evaluate the fluid balance and dry weight with whole body bioelectrical impedance analysis (BIA) in patients with maintenance hemodialysis ( MHD). Methods Twenty patients in stable condition with MHD for more than one year were selected ( MHD group). Extra-cellular water ( ECW) and intra-cellular water (ICW) were measured by BIA before hemodialysis, after hemodialysis and at intervals of hemodialysis (24 h and 48 h after hemodialysis), and related parameters were calculated. Whether patients with MHD achieved dry weight at 0 h was analysed, and the effects of average daily urine volume on ECW and ICW were explored. Another 20 healthy volunteers were served as controls. Results Compared with control group, ECW retrieved by ideal body weight was significantly higher before hemodialysis in MHD group (P<0.05). In MHD group, ECW was significantly lower after hemodialysis than that before hemodialysis (P < 0.05). ECW/total body water (TBW) was significantly lower and ICW/TBW was significantly higher after hemodialysis than those before hemodialysis and at intervals of hemodialysis ( P < 0.05). ICW and ECW at each time point were significantly related to body weight. ICW and ECW retrieved by ideal body weight at 0 h and 24 h of those who achieved dry weight were significantly higher than those who did not achieve dry weight ( P < 0.05). ECW and ICW before hemodialysis and 24 h after hemodialysis were significantly lower in those with urine volume <400 mL/d than those with urine volume ≥400 mL/d (P <0.05). Conclusion BIA analysis indicates that changes of fluid balance before hemodialysis, after hemodialysis and at intervals of hemodialysis in patients with MHD are characterized by ECW, and ECW/TBW is a more sensitive parameter. ICW and ECW retrieved by ideal body weight may be sensitive parameters to determine the dry weight in patients with MHD.

The 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) catalyzes the conversion of HMG-CoA to mevalonate in mavalonic acid pathway, which is the first committed step for isoprenoid biosynthesis in plants. However, it still remains unclear whether HGMR gene plays a role in the isoprenoid biosynthesis in Dendrobium officinale, an endangered epiphytic orchid species. In the present study, a HMGR encoding gene, designed as DoHMGR1 (GenBank accession JX272632), was identified from D. officinale using the reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) methods, for the first time. The full length cDNA of DoHMGR1 was 2 071 bp in length and encoded a 562-aa protein with a molecular weight of 59.73 kD and an isoelectric point (pI) of 6.18. The deduced DoHMGR1 protein, like other HMGR proteins, constituted four conserved domains (63-561, 147-551, 268-383 and 124-541) and two transmembrane motifs (42-64 and 85-107). Multiple sequence alignment and phylogenetic analyses demonstrated that DoHMGR1 had high identity (67%-89%) to a number of HMGR genes from various plants and was closely related to Vanda hybrid cultivar, rice and maize monocots. Real time quantitative PCR (qPCR) analysis revealed that DoHMGR1 was expressed in the three included organs. The transcripts were the most abundant in the roots with 2.13 fold over that in the leaves, followed by that in the stems with 1.98 fold. Molecular characterization of DoHMGR1 will be useful for further functional elucidation of the gene involving in isoprenoid biosynthesis pathway in D. officinale.

BACKGROUND: Opiate drugs are widely used to control chronic cancer pain, which brings many adverse reactions. Transplantation of sodium alginate-polylysine-alginate microencapsulated bovine adrenal chromaffin cell (BCC) has reported to be used as chronic cancer pain controllers. However, the high price and poor strength of polylysine limited its clinical application. Chitosan is characterized by sufficient resource, low price and good biocompatibility, which is a substitute for polylysine.OBJECTIVE: To study the effect of xenotransplantation of sodium alginate-chitosan-alginate (ACA) microencapsulated BCC on patients with advanced cancer pain.DESIGN, TIME AND SETTING: A retrospective case analysis. All cases were obtained from Department of Oncology, Affiliated Zhongshan Hospital of Dalian University from January 2007 to December 2008.PARTICIPANTS: Totally 10 patients with advanced cancer, including 1 female and 9 males, aged 46-78 years. According to visual algetic mimic scale (VAS), 3 patients suffered moderate pain and 7 cases suffered severe pain.METHODS: Microencapsulation method was applied to encapsulate BCC with ACA membrane and transplant the microencapsulated BCC (5-7)×10~6 into the subarachnoids pace of 10 patients.MAIN OUTCOME MEASURES: The degree of pain release, duration of analgesic effect, as well as adverse reaction.RESULTS: All 10 patients had pain relief rapidly after transplantation in varying degrees. Complete pain relief was shown in 2 cases, medium relief in 1 case, slight relief in 4 cases. Slight irritation of cauda eguina was presented after transplantation, which could disappear within 3-5 days.CONCLUSION: Xenotransplantation of ACA microencapsulated BCC into the spinal subarachnoids pace of patients with cancer pain can produce analgesic effect promptly, significantly, and safely.

MTT Colorimetric method is usually applied for measuring the living animal cell number. By changing the reaction temperature and the reaction time as well as the colorimetric wavelength, the improved MTT colorimetric method was established to count the living bacterial cell number. This new method was used to measure the living cell concentration in the process for culturing bacteria PBW1. The results measured by the improved MIT colorimetric method and dilute plate method are similar. Compared with other methods including the dilute plate method, the improved MTT colorimetric method has many advantages such as accuracy, quickness.

Objective To investigate the effects of metabolic syndrome(MS)on the structure and function of artery in patients with essential hypertension(EH).Methods One hundred forty-eight patients with EH were classified as EH with MS(EH+MS)or EH alone and healthy subjects(n=30)as control.Carotid intima-media thickness(IMT),brachial artery flow-mediated vasodilation(FMD)and non-flow-mediated vasodilation(NMD)were measured by Dopple ultrasonography.Results Carotid IMT(EH+MS:1.0?0.3 vs EH:0.8?0.2 vs control: 0.5?0.1 mm)and hsCRP(EH+MS:0.9?0.4 vs EH:0.7?0.3 vs control:0.4?0.2 mg/L)were significantly higher in EH+MS patients than that in EH+nonMS patients and control subjects(P all

Objective To compare the clinical efficacies of totally laparoscopic and laparoscopy-assisted radical total gastrectomies.Methods The retrospective cohort study was conducted.The clinicopathological data of 373 patients with gastric cancer who underwent totally laparoscopic or laparoscopy-assisted radical total gastrectomies from the 7 medical centers in China (82 patients in the Affiliated Hospital of Qinghai University,80 in the Traditional Chinese Medicine Hospital of Guangdong Province,60 in the First Affiliated Hospital of Xiamen University,51 in the Hangzhou First People's Hospital,46 in the First Affiliated Hospital of Xi'an Jiaotong University,30 in the Second Affiliated Hospital of Jilin University and 24 in the Xijing Hospital of the Fouth Military Medical University) between January 2015 and December 2016 were collected.Of 373 patients,the 183 and 190 patients were respectively divided into the totally laparoscopic group (undergoing totally laparoscopic radical total gastrectomy) and laparoscopy-assisted group (undergoing laparoscopy-assisted radical total gastrectomy),including 63 and 19 in the Affiliated Hospital of Qinghai University,36 and 44 in the Traditional Chinese Medicine Hospital of Guangdong Province,25 and 35 in the First Affiliated Hospital of Xiamen University,20 and 31 in the Hangzhou First People's Hospital,10 and 36 in the First Affiliated Hospital of Xi'an Jiaotong University,17 and 13 in the Second Affiliated Hospital of Jilin University,12 and 12 in the Xijing Hospital of the Fouth Military Medical University.Routine five-port method was applied for laparoscopic radical total gastrectomy and D2 lymphadenectomy.Roux-en-Y anastomosis was applied for digestive tract reconstruction,and digestive tract reconstruction was performed under laparoscopy in the totally laparoscopic group and via upper abdominal median incision in the laparoscopy-assisted group.Observation indicators:(1) operation and postoperative situations;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect the postoperative overall survival and tumor recurrence or metastasis up to March 2017.Measurement data with normal distribution were represented as x±s.Comparison between the groups was analyzed by the t test.Measurement data with skewed distribution were represented as M (range).Comparisons of count data were analyzed using the chi-square test and Fisher exact probability.Results (1)Operation and postoperative situations:all the patients in the 2 groups underwent successful operations,without perioperative death.Esophagojejunostomy methods of 183 patients in totally laparoscopic group:conventional circular stapler method were performed in 28 patients,anti-puncture circular staplar method in 6 patients,OrVilTM method in 5 patients,functional end-to-end esophagojejunostomy method in 65 patients and peristalsis side-to-side esophagojejunostomy method in 79 patients.Conventional circular stapler method was applied to 190 patients in the laparoscopy-assisted group.Operation time,time of esophagojejunostomy,length of assisted incision,using time of analgesics and expenses of digestive tract reconstruction were (238± 55)minutes,(29±9)minutes,(5.1 ± 1.1)cm,(2.2±l.0)days,(18 332±2 141)yuan in the totally laparoscopic group and (217±39)minutes,(26±7)minutes,(7.8 ±2.0)cm,(2.7± 0.9)days,(16 237 ± 1 923)yuan in the laparoscopy-assisted group,respectively,with statistically significant differences between the 2 groups (t =4.324,3.455,-16.835,-5.561,9.949,P＜0.05).The cases with postoperative overall complications,anastomosis leakage,anastomosis stricture,anastomosis bleeding and expenses of esophagojejunostomy were respectively 24,9,7,5,(9 668±2 814)yuan in the totally laparoscopic group and 24,8,9,6,(9 331 ±2 067)yuan in the laparoscopy-assisted group,with no statistically significant difference between the 2 groups (x2 =0.036,0.107,0.189,0.059,t=1.322,P＞0.05).All the patients with postoperative complications were cured by symptomatic treatment.(2) Follow-up and survival situations:of 373 patients,336 were followed up for 4-26 months,with a median time of 13 months,including 166 in the totally laparoscopic group and 170 in the laparoscopy-assisted group.During the follow-up,cases with overall survival,tumor recurrence and tunor metastasis were respectively 150,10,16 in the totally laparoscopic group and 154,9,16 in the laparoscopy-assisted group (10 and 9 patients in the totally laparoscopic and laparoscopy-assisted groups with simutaneous tumor recurrence and metastasis),showing no statistically significant difference between the 2 groups (x2 =0.075,0.010,P＞0.05).Conclusions Total laparoscopic and laparoscopyassisted radical total gastrectomies are safe and feasible,with equivalent overall outcomes and effects of esophagojejunostomy.Compared with laparoscopy-assisted radical total gastrectomy,the postoperative pain time of patients in total laparoscopic radical total gastrectomy is less,but there are longer time of esophagojejunostomy and higher expenses of digestive tract reconstruction.
