Objective To investigate the clinical characteristics, risk factors and prevention measures of carbapenem-resistant Klebsiella pneumoniae (CRKP) infection. Methods Thirty-nine cases whose CRKP isolation and culture were positive and who were confirmed with nosocomial infection in 2nd affiliated hospital medical school of Zhcjiang University between July 2006 and July 2008 were retrospectively investigated. Results There were 22 (56.4%) sputum specimens among CRKP samples. The average age of the patients was 64.0 years old and the average length of staying in hospital was 80.8 days. There wcre 36 patients who had been in intensive care unit (ICU) within 2 weeks and 26 were conscious disturbance,38 received urethral catheterization, 34 inserted with central venous catheter, 32 received tracheal intubation and 30 assisted with mechanical ventilation. There were 27 (69. 2 % ) patients who were co-infected with other bacteria and 8 were co-infccted with fungi. The mortality was 46. 2% in patients with CRKP infection. Before CRKP-positive culture, 27 (69.2%)experienced >4 kinds of antibiotics with the majority of β-lactams/β-lactamase inhibitors and carbapenems.Conclusions CRKP infection frequently occurrs in elder and patients who prolonged stay in hospital,especially patients in ICU. Invasive procedures could increase the infection opportunities.

Studies have shown that women's menopause caused by permanent cessation of ovarian function is closely related to lipid metabolism disorders. Er-xian Decoction has been used in the clinical treatment for gynecological diseases and has a good effect on diseases related to reduced sex hormone function. In this study, metabolomics was performed on bilateral ovariectomized model rats within 12 weeks after modeling to mimic the physiological state of menopausal women in different menopausal stages and Er-xian Decoction dosed model rats. The results of liver oil red O staining sections showed lipid metabolic disorder of bilateral ovariectomized model rats and the regulating effects of Er-xian Decoction. 46 potential biomarkers (6 steroid hormones, 3 sphingolipids, 11 phospholipids and 26 glycerides) in plasma and 32 potential biomarkers (1 steroid hormones, 20 phospholipids and 11 glycerides) in liver were obtained based on lipidomics analysis. Then, we analyzed the differential metabolic pathways and construct the lipid metabolism network significantly regulated by Er-xian Decoction. The results provided valuable information for in-depth understanding of the gradual changes on lipid metabolism disorders under menopausal conditions and the characteristics and mechanisms of compound Er-xian Decoction's regulatory effects. The study complied with the procedures established by the Animal Experiment Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and passed the animal experiment ethics examine (No. 00000918).

Objective To explore the serum anti-Mullerian hormone (AMH) level in women of childbearing age with normal menstrual cycles. Methods A total of 1 423 women with regular menstrual cycles were selected and divided into 5 groups according to their ages, i.e.≤25, 26-30, 31-35, 36-40,≥41 years. Their serum levels of AMH were measured, and the relationship between AMH and age was analyzed. Results The serum AMH levels of 5 groups according to ages (≤25, 26-30, 31-35, 36-40, ≥41 years) were 3.62, 3.10, 2.27, 1.07, 0.45μg/L, respectively. The comparison of serum AMH levels in different age groups had significant difference (P<0.01). Serum AMH level declined with increasing age,and dropped significantly after 36. The serum AMH level and age showed a negative correlation with significant difference (r=-0.374, P<0.01). Quadratic regression of logAMH proximally reflected the relationship between AMH and age. Conclusion AMH determination for women of childbearing age could provide reference for the evaluation of ovarian function.

OBJECTIVETo explore effects and action mechanism of warm moxibustion on regulation of blood lipids and anti-atherosclerosis.
METHODSForty-one male Japanese big-ear white rabbits were randomly divided into a blank group (10 rabbits), a model group (10 rabbits), a moxibustion group (10 rabbits) and a medication group (11 rabbits). Normal diet was applied in the blank group while high-cholesterol diet combined with injection of bovine serum albumin were applied in the rest groups to establish rabbit model of atherosclerosis. After establishment, the model group was not intervened and warm moxibustion was applied in the moxibustion group at "Zusan-li" (ST 36) and "Shenque" (CV 8), 10 min per acupoint per day for continuous 4 weeks. The medication group was treated with intragastric administration of lovastatin capsule (3.6 mg/kg) for continuous 4 weeks. The level of blood lipids, such as total cholesterol (TC), triglyceride (TG), and content of CD40 ligand (CD40L), soluble CD40 ligand (sCD40L) and expression of nuclear factor NF-kappaB were tested after 4 weeks.
RESULTSCompared with the model group, the moxibustion group and medication group could effectively reduce the contents of TC and low density lipoprotein (all P < 0.05), lower the level of sCD40L [(8.310 +/- 1.221) ng/mL in the model group, (7.097 +/- 0.846) ng/mL in the moxibustion group and (7.354 +/- 0.631) ng/mL in the medication group], reduce expression of CD40L [(0.235 +/- 0.179) mm2 in the model group, (0.072 +/- 0.079) mm2 in the moxibustion group and (0.039 +/- 0.015) mm2 in the medication group] and NF-kappaB [(0.145 +/- 0.052)mm2 in the model group, (0.052 +/- 0.012) mm2 in the moxibustion group and (0.036 +/- 0.013) mm2 in the medication group], indicating the significant difference (P < 0.05, P < 0.001). There was no statistical difference between the moxibustion group and medication group (all P > 0.05).
CONCLUSIONThe warm moxibustion has great effect on regulation of blood lipids and anti-atherosclerosis, in which lowering expression of CD40-CD40L could be one of possible mechanisms to take effect of anti-atherosclerosis.

AIM: To investigate the alterations of tear film after sutureless large incision manual cataract extraction (SLIMCE). METHODS: Sixty-eight SLIMCE operation eyes were studied with slit-limp microscope, break- up time (BUT), SchirmmerⅠtest (SⅠt),and fluorescence(FL) to observe the alterations of tear film at different time points in postoperation. Impression cytology and microphoto-analyses technique were also applied to observe the goblet cells at different time points postoperation(7,14,30,60,90 days). RESULTS: Subjective complaint of dry eye within 90 days after the operations were significantly increased compare with preoperations(5-27,23,19,16,13; 2-16,14,8,6,3). The schirmmer Ⅰ test were greatly increased in 14 days postoperation(10.1±4.5;15.0±4.7,13.8±5.7),the mean scores of fluorescence increased (0-17,9,5;0-8,3,1) and the mean break-up time decreased in 30 days post-operation(10.3±2.2;5.5±2.3,7.0±2.4,7.9±2.2) (P<0.05). CONCLUSION: SLIMCE operation have effect on the stability of tear film.

Thirteen patients with colorectal lesions underwent laparoscopic surgery from January to December 2019. Before surgery, 5.0 ml autogenous blood was injected under colonoscopy into the inferior margin and opposite sides of the lesion for localization. The operation time,success rate,complications,location efficiency and postoperative pathology were evaluated. The autologous blood tattooing was easily applied for all patients without complication. At laparoscopic surgery,the lesions of all patients were clearly visualized except one obese patients with rectal tumors, because the tumor was located below the retroperitoneal fold. No blood diffusion and leakage,and local inflammatory responses were observed. The surgical margins of all samples were tumor negative. Preoperative tattooing with autologous blood is recommended as an easy,safe and economical procedure for colonoscopic surgery in patients with colorectal lesions.

Objective To explore the significance of the plasma procalcitonin (PCT) level for directing antibiotic therapy in elderly patients with ventilator-associated pneumonia (VAP).Methods The 50 elderly patients with VAP were randomly separated into the regular therapy group and the PCT-directed therapy group. The regular therapy group was given regular antibiotic therapy, while the antibiotic therapy was decided according to the plasma level of PCT in the PCT-directed therapy group. The used time and utilization rate of antibiotics, as well as inflammatory indicators including white blood cells, neutrophils, C-reactive protein (CRP) and clinical pulmonary infection score (CPIS) were compared between the two groups. Results After treatment, there were no significant differences in white blood cells, neutrophils and CRP between the PCT-directed therapy group and regular therapy group [(8.9 ± 3.5 ) × 109/L vs. (9.4 ± 3.7) × 109/L, 0.62 ± 0.04 vs.0.60±0.04, (18.7±8.5) mg/Lvs. (21.6±6.0) mg/L, t=0.47, 1.84 and 1.37, allP>0.05],but the CPIS was markedly lower in PCT-directed therapy group than in regular therapy group [(4.0± 1.4) scores vs. (4.7± 1.0) scores, t= 2. 18, P<0.05]. The neutrophils, CRP and CPIS were significantly lower after treatment than before in the both groups. The concentration of PCT was decreased after treatment than before [(0.5 ± 0.9) mg/L vs. (1.7 ± 0.7) mg/L]. Meanwhile, the time using antibiotics was longer in regular treatment group than in PCT-directed therapy group [(8.72±1.32) d vs. (5.17±0.72) d, t=11.96, P<0.01], the utilization rate of antibiotics was higher (95.2 % vs. 55.2 %, χ2 = 12.41, P<0.01) in regular treatment group. Conclusions Using PCT levels for directing treatment in elderly patients with VAP can achieve better curative effect and reduce the use of antibiotics.
