As a active nidus it can attac h, invade and damage the renal epithelium of collecting ducts and papilla, and t hen form apatite which being the center to induce formation of kidney stones. I n the paper, the research progress on nanobateria contained in kidney stones and its role in kidney stones formation were summarized. The simulation in vitro a nd animal models of kidney stones formation induced by nanobateria were discusse d.

Objective To compare the therapeutic efficacy between laparoscopic peritoneal vaginoplasty and sigmoid loop vaginoplasty. Methods A total of 29 cases of congenital absence of vagina received either laparoscopic peritoneal vaginoplasty (Peritoneal Group, 14 cases) or sigmoid loop vaginoplasty (Sigmoid Group, 15 cases) from March 1998 to April 2003. Results The operation failed in 1 case in the Peritoneal Group, requiring a conversion to open sigmoid loop vaginoplasty. Both groups had no surgical complications or postoperative pyrexia. The operating time of the Peritoneal Group (118 9?19 0 min) was significantly shorter than that of the Sigmoid Group (202 0?18 6 min) ( t =-11 674, P =0 000). And the intraoperative blood loss of the former (36 2?12 6 ml) was significantly less than that of the latter (105 3?46 3 ml) ( t =-5 205, P =0 000). The conditions of reconstructed vagina of both groups were basically the same, but the vagina length of the Sigmoid Group (10 8?1 1 cm) was significantly greater than that of the Peritoneal Group (9 0?0 8 cm) ( t =-4 882, P =0 000). Among the Sigmoid Group, 3 cases had somewhat more amount of vaginal secretion and 4 cases had abnormal-smelling secretion. Patients in both groups reported the same satisfactory degree of sexual life. Conclusions Laparoscopic peritoneal vaginoplasty and sigmoid loop vaginoplasty present a similar therapeutic efficacy, but the former gives less surgical invasion than the latter.

BACKGROUND: Dynamic glucose monitoring can reflect the fluctuation of blood glucose by successive examination at the interval of 5 minutes,which contributes to the overall and objective evaluation of glucose metabolism.OBJECTIVE: To investigate the tendency and characteritics of blood glucose fluctuation in type 2 diabetic and normal subjects. DESIGN: A case-controlled retrospective experiment based on patients and healthy controls.SETTING: Endocrine Metabolism Ward and Clinic of Sixth People's Hospital Affiliated to Shanghai Jiaotong University.PARTICIPANTS: Totally 47 patients were newly diagnosed as having type 2 diabetes mellitus at Endocrine Metabolism Ward and Clinic, Sixth People's Hospital Affiliated to Shanghai Jiaotong University, between December 2002 and July 2004. They had not received intervention (diet, exercise or medicine) before. Those with acute complications such as ketoacidosis and hyperosmolar coma were excluded. Meanwhile, 43 healthy controls were selected from those coming for routine health examinations, and they had no family history of diabetes, and impaired fasting glucose and impaired glucose tolerance were excluded. Their lipid and liver and kidney indexes as well as blood pressure were within normal range. They all signed informed consent.METHODS: Totally 43 normals and 47 patients with type 2 diabetes mellitus were subjected to dynamic glucose monitoring for consecutive (71±10) hours, and (846±122) results of glucose level were obtained.MAIN OUTCOME MEASURES: The average glucose level, diurnal maximum and minimum, fluctuation amplitude, the average preprandial and postprandial glucose values and the time percentage of diurnal glycemic fluctuations.RESULTS: According to the objective of this study, all subjects went through the experiment without loss. ① The fluctuation tendency of blood glucose in two groups: The average glucose, diurnal maximum and maximum fluctuation amplitude in type 2 diabetes mellitus group were [(12.2±2.6) mmol/L], [(18.5±2.7) mmol/L] and [(11.2±2.8) mmol/L,respectively], which were significantly higher than those in control group [(5.3±0.5), (7.8±1.4) and (3.9±1.6) mmol/L](t=16.68, 23.04, 15.14;P ＜ 0.001). ② The percentage of diurnal glycemic fluctuations time: The time percentage of glycemic fluctuations within 2.8-7.8 mmol/L was 99％ (87％-100％) in control group, 95％ (28％-100％) and 62％ (6％-100％) when blood glucose.was increased to ＞ 7.8 mmol/L or ＞ 11.1 mmol/L in type 2 diabetes mellitus group.CONCLUSION: Blood glucose in type 2 diabetes mellitus has been proved to fluctuate at a relatively higher level than that of normals, with greater fluctuation amplitude.Dynamic glucose monitoring is benefical to evaluating the tendency and characteritics of blood glucose fluctuations in type 2 diabetic and normal subjects.

Objective To explore the impact of Microsurgical operation through lateral fissure-insula lobe approach in the treatment of hypertensive cerebral hemorrhage in basal ganglia region on the clinical curative effect.Methods Selected 90 cases of patients with hyper-tensive cerebral hemorrhage in basal ganglia region in our hospital from April 2013 to December 2015.According to the random number table method,they were divided into the observation group and the control group.Regarded the even numbers as the observation group while the odd numbers as the control group,with 45 cases in each group.Patients of the two groups were all performed general anaesthesia with tracheal in-tubation.And patients of the control group were given large trauma craniotomy,while patients of the observation group were treated by micro-surgical operation through lateral fissure-insula lobe approach.Recorded the situation of surgery and postoperative recovery of patients in the two groups.In addition,compared the postoperative complications and evaluated living conditions of the two groups through activity of daily living scale(ADL)half a year after surgery.Results The good rate of recovery in the observation group was 84.44% (38 /45),while it was 51.11%(23 /45)in the control group,and there was statistically significant difference between the two groups(χ2 =11.447,P =0.000).Be-sides,the mortality rate of the observation group was 0(0 /45)half a year after surgery,while it was 8.89%(4 /45)in the control group,and there was statistically significant difference between the two groups(χ2 =4.186,P =0.041).The operation time of observation group and the automatic opening time in the observation group were obviously shorter than that of the control group(P <0.05).Moreover,the hematoma clearance rate and GCS score of the observation group 1 week after operation were significantly higher than those of the control group (P <0.05).The incidence of postoperative complications of the observation group was 8.89%(4 /45),which was significantly lower than 31.11%(14 /45)in the control group,and there was significant difference(P <0.05).Conclusion It has many advantages such as shorter operative time,faster postoperative recovery,and higher hematoma clearance rate to apply microsurgical operation through lateral fissure-insula lobe approach in the treatment of hypertensive cerebral hemorrhage in basal ganglia region.Besides,it pays attention to protecting cerebral vascular of patients.The clinical treatment effect is ideal and safe.Therefore,it is worth popularizing in clinical application.

The diversity in Tibetan kefir grains and dynamics of the microbial community during the fermentation of Tibetan kefir by PCR-DGGE fingerprinting technique were studied.The results showed that bacterial community of Tibetan kefir grains was more complex than that of yeast.The bacteria communities between different Tibetan kefir grains showed 78%～84% similarity, and yeast 80%～92%.Bands B, E and N of DGGE profiles of the microbial community during fermentation of Tibetan kefir were present throughout the fermentation.Analysis of sequence date showed the majority of the DGGE bands of bacteria community corresponded to LAB, and the most intense band (band E) was completely homology to Lactococcus lactis.

Strong inhibition of Bacillus subtilis strain NJ-18 on mycelia growth of Alternaria solani was observed in the antagonistic tests by cylinder plate methods, and the inhibition width was 21.5 mm. Observation under microscope found that the supernatant of fermentation from NJ-18 could make the pathogen hyphae cells malformed and swelled, and consequently the growth of the pathogen was inhibited. Determining of the colonization in potato plants by the signed rifampicin-resistance in NJ-18 showed that it could colonize well in the plants, the colonization quantity of NJ-18 in the root and stem of the potato detected 30 days after fermentation irrigation was 103 CFU/g plant’s fresh weight. In pot experiment, we inoculated the tomato plants with the spore suspensions of Alternaria solani after spraying the fermentation of NJ-18, the results were investigated in 14 days and the efficacy in controlling the disease was 72.9%, which was significantly higher than 45.7%, the efficacy resulted from spray treatment of 2000 fold dilution of 50% iprodione wetable powder.
