Objective To investigate the effect of controlled-release dinoprostone on odinopoeia in prolonged pregnancy.Methods 94 cases of prolonged pregnancy women selected in First People's Hospital in Pinghu City from January 2012 to November 2014 were randomly divided into two groups, 47 cases in each group.The control group were given misoprostol to induce labour, while the observation group were given controlled-release dinoprostone to induce labour.The Bishop score, odinopoeia effect and adverse reactions were compared between two groups and expressions of prostaglandin E2(PGE2) and PGF2αin deciduas of observation group were compared between induction success group and induction failure group. Results The Bishop score in observation group was higher than that in control group 12h post-administration(P<0.05).The total efficiency of cervical ripening, the induction success rate in observation group were higher than those in control group(P<0.05).The adverse reactions and the incidence of complications between two group was not statistically significant.The PGE2 and PGF2αconcentrations in induction success group were higher than those in induction failure group(P<0.05).Conclusion The controlled-release dinoprostone could achieve similar security of misoprostol in odinopoeia, but has more significant induction effect.

Objective To analyze clinical characteristics of patients with juvenile myoclonic epilepsy in China. Methods Eighty-seven patients were retrospectively studied in the aspects of family history, febrile seizures, clinical features, EEG, treatment effect. Results There was a female preponderance of incidence. In contrast to the earlier studies we found a high incidence of febrile seizures and a low incidence of family history. myoclonic seizures began at age of ( 13.1?3.4) years. That combined with generalized tonoclonic seizures began at age (14.3?3.8) years. Absence seizures began at age (10.0?3.3) years. The correct diagnosis was delayed at a mean of 2.2 years from onset of the disease. The incidence of abnormal EEG discharge could be enhanced by hyperventilation, photic stimulation and sleep. Sixteen patients who had received carbamazepine or phenytoin were experienced aggravation of seizures. Forty-five patients who received monotherapy with sodium valproate remained seizure-free in a follow-up longer than 0.5 years. Conclusions Failure to recognize JME may result in uncontrolled seizures, and even aggravated of seizures by using antiepilepsy drugs. Effective treatment was achieved with small doses of sodium valproate.

In experiment 4, the samples were digested with 0.05 g/L trypsin digestion for 30 minutes×2, fol owed by 1 g/L col agenase digestion for 60 minutes. Fol owing morphology observation under a microscope, we studied the most suitable method for isolating human amniotic mesenchymal stem cells.
RESULTS AND CONCLUSION:Digestion with 0.05 g/L trypsin for 30 minutes twice fol owed by 1 g/L of col agenase digestion of 60 minutes was the most suitable isolation and culture condition in vitro. cells became elongated fusiform or star-shaped with rich cytoplasm, and nuclei were round with 1-3 nuts. We can harvest the most number of human amniotic mesenchymal stem cells using the method described in experiment 4.

AIM:To examine the expression profiles of both genes and proteins in hippocampus of rats with temporal lobe epilepsy(TLE)for revealing the molecular mechanisms of TLE and looking for the candidate targets and new therapeutic approaches in clinical practice.METHODS:Rat temporal lobe epilepsy was induced by administration of lithium chloride and pilocarpine(LiCl-PILO).The expression spectra of genes and proteins were constructed through the techniques of cDNA microarray,two-dimensional(2D)electrophoresis and Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF MS).Subsequently,the differentially expressed genes and proteins were identified and analyzed.RESULTS:There were 192 genes of differential expression observed in hippocampal tissues of LiCl-PILO-induced temporal lobe epilepsy,and 159 genes have been registered in Genbank database,in which 84 genes were up-regulated while 75 genes were down-regulated.78 protein spots of differential display were screened out,in which 31 proteins were detected to be down-regulated and 47 were up-regulated.Finally,5 proteins were identified.CONCLUSION:These genes and proteins found in our study may play pivotal roles in the pathogenic mechanisms of epilepsy and may promise new therapeutic targets for refractory epilepsy in the future.

Objective To evaluate the effect of the LEMON method in predicting difficult air-way.Methods A total of 1 528 patients scheduled for elective surgery requiring tracheal intubation under general anaesthesia,680 males and 848 females,aged 18-83 years,ASA physical status Ⅰ orⅡ,were enrolled in the study.We used the LEMON method to assess airway conditions before an-aesthesia and recorded the scores.The primary end point was difficult tracheal intubation.The sec-ondary end point was difficult laryngoscopy.Receiver operating characteristic (ROC)curve analysis and the area under the curve (AUC)were used to evaluate the clinical effect of the LEMON mothod. Results There were 37 cases with difficult tracheal intubation and 106 cases with difficult laryngosco-py.The incidence of difficult tracheal intubation and difficult laryngoscopy were 2.4% and 6.9%,re-spectively.The area under the curve of the LEMON method for predicting difficult laryngoscopy and difficult tracheal intubation were 0.884 (95% CI 0.867-0.899)and 0.934 (95% CI 0.921-0.946), respectively.Conclusion The LEMON method has good clinical effect in predicting difficult airway.

Objective:To evaluate the effectiveness of Simplified Airway Risk Index (SARI) score in predicting difficult airway in Chinese patients.Methods:One thousand and three hundred patients of both sexes, aged 18-90 yr, with American Society of Anesthesiologists physical status Ⅰ-Ⅲ, undergoing tracheal intubation with the laryngoscope under general anaesthesia, were enrolled in this study.SARI scores (including 7 evaluation items: mouth opening, thyromental distance, Mallampati classification, neck mobility, mandibular protrusion, body weight, and history of difficulty in tracheal intubation) were determined before anesthesia induction.The receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the effectiveness of SARI scores in predicting difficult tracheal intubation and difficult laryngoscopy.Results:The AUC and 95% confidence interval of the SARI score, mouth opening, modified Mallampati classification and thyromental distance in predicting difficult tracheal intubation were 0.91 (0.89-0.93), 0.84 (0.82-0.86), 0.81 (0.79-0.83) and 0.83 (0.80-0.85), respectively.The AUC and 95% confidence interval of the SARI score, mouth opening, modified Mallampati classification and thyromental distance in predicting difficult laryngoscopy were 0.90 (0.88-0.91), 0.79 (0.76-0.81), 0.76 (0.74-0.78) and 0.73 (0.70-0.75), respectively.The AUC of SARI scores in predicting difficult tracheal intubation and difficult laryngoscopy was significantly larger than that of the mouth opening, modified Mallampati classification and thyromental distance ( P<0.05). Conclusion:The SARI score produces better efficacy in predicting tracheal intubation and difficult laryngoscopy in Chinese patients.

Objective:To investigate the prevalence of hyperuricemia (HUA), patients′ awareness of HUA, and related factors among elderly in community.Methods:The health check-up data of 6 897 residents aged over 65 years in Gumei Community of Shanghai were collected from January 2019 to January 2020. There were 1 156 subject with increased serum uric acid levels (HUA group) and 5 741 with normal uric acid levels (non-HUA group). The differences of clinical indicators between HUA group and non-HUA group were analyzed and the risk factors of HUA was determined by multivariate logistic stepwise regression. A questionnaire survey on the knowledge of HUA and the adoption of relevant health behaviors was conducted among HUA patients.Results:The overall prevalence was 16.8% (1 156/6 897) in this population. The prevalence in males was significantly higher than that in females[26.4%(842/3 195) vs. 8.5%(314/3 702), P<0.001); and the prevalence in females increased with age (χ 2=7.56, P=0.023). Body mass index(BMI), waist circumference(WC), total cholesterol(TC), triglyceride(TG), serum creatinine, alanine aminotransferase(ALT) and albumin/urine creatinine ratio(UACR) in the HUA group were significantly higher than those in the non-HUA group, while estimated glomerular filtration rate(eGFR) and high-density lipoprotein(HDL) were lower than those in the non-HUA group (all P<0.01). The prevalence of hypertension, decreased renal function, overweight or obesity, abdominal obesity, fatty liver and renal cyst in HUA group was significantly higher than that in non-HUA group (all P<0.01). High values of TG, low-density lipoprotein(LDL), WC, hypertension and fatty liver were risk factors for HUA( OR=1.14, 1.20, 1.03, 1.43, 2.19; P<0.01); while female gender, eGFR, HDL and glycosylated hemoglobin A1c(HbA1c) were protective factors for HUA( OR=0.32, 0.94, 0.65, 0.78; P<0.01). The questionnaire survey was conducted among 1 090 HUA patients, and the results showed that 73.2% (798 cases) were aware of the disease after the health check-up results released; only 30.9% (337 cases) knew the diagnostic criteria of HUA, 21.1% (230 cases) knew that HUA needed life-long follow-up care, 56.3% (614 cases), 49.2% (536 cases) and 47.9% (522 cases) thought that HUA should eat less seafood, broth and soya bean products, 17.0%(185 cases) were atcohol drinker and the awareness rates of above questions in patients with gout were higher than those in patients without gout ( P<0.05). Conclusion:The study shows that the prevalence of HUA among the elderly in Gumei community of Shanghai is high, and the HUA related knowledge levels and health behavior performance are not ideal, especially for HUA patients without gout, therefore health education should be strengthened for elderly residents in the community.

Objective To analyze the effects of dexmedetomidine(Dex) on levels of inflammatory cytokines in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods From April 2015 to April 2017,94 patients with acute exacerbations of COPD who received mechanical ventilation in Wenling Hospital Affiliated to Wenzhou Medical College were randomly divided into two groups according to the digital table,with 47 cases in each group. Group A was given Dex,and group B was given midazolam. The levels of TNF - α,IL - 1, hs - CRP between the two groups were compared. Results There were no statistically significant differences in TNF - α,IL - 1,hs - CRP between the two group before treatment (all P > 0. 05). One day after treatment,the levels of TNF - α,IL -1,hs - CRP in group A were (92. 99 ± 15. 25)ng/ L,(68. 63 ± 14. 53)ng/ L,(15. 44 ± 4. 92)mg/ L, respectively,which in group B were (150. 63 ± 20. 78)ng/ L,(91. 13 ± 12. 58)ng/ L,(19. 35 ± 5. 17)mg/ L,respec-tively,there were statistically significant differences between the two groups(t = 2. 736,2. 503,2. 421,P = 0. 008, 0. 012,0. 015). Three days after treatment,the levels of TNF - α,IL - 1,hs - CRP in group A were (73. 37 ± 11. 01)ng/ L,(51. 52 ± 9. 16) ng/ L, (14. 82 ± 3. 29) mg/ L, respectively, which in group B were (123. 80 ± 19. 62)ng/ L,(73. 46 ± 17. 36) ng/ L, (18. 77 ± 4. 02 ) mg/ L, respectively, there were statistically significant differences between the two groups(t = 2. 184,2. 354,2. 098,P = 0. 031,0. 022,0. 039). Five days after treatment, the levels of TNF - α,IL - 1,hs - CRP in group A were (63. 54 ± 13. 06)ng/ L,(34. 04 ± 8. 13) ng/ L,(13. 84 ± 4. 13)mg/ L,respectively,which in group B were (76. 63 ±17. 39)ng/ L,(50. 66 ± 9. 17)ng/ L,(14. 27 ± 3. 95)mg/ L, respectively,there were statistically significant differences between the two groups( t = 1. 906,2. 082,1. 834,P =0. 067,0. 041,0. 081). Compared with group B,the ICU time in group A was significantly decreased[(9. 27 ± 1. 63) d vs. (7. 16 ± 1. 21)d,t = 2. 215,P = 0. 031](t = 2. 215,P = 0. 031). There was no statistically significant difference in the incidence rate of multiple organ dysfunction syndrome between the two groups at 5 days after treatment (χ2 =2. 286,P = 0. 132). Conclusion Dex can effectively inhibit inflammation cytokines of the mechanical ventilation COPD patients in acute exacerbation,and can reduce the ICU time.

BACKGROUNDSubdural hematoma (SDH) is a common complication of spontaneous intracranial hypotension (SIH). To date, the management of SDH caused by SIH remains controversial. In this paper, we reviewed the clinical course of SDH in patients with SIH, and discuss the underlying mechanism and attributing factors for rapid resolution of subdural hematomas after epidural blood patch (EBP) surgery.

METHODSWe retrospectively reviewed a cohort of seventy-eight SIH patients diagnosed and treated with targeted EBP in our neurology center. Patients who received early CT/MRI follow-up after EBP operation were included.

RESULTSA series of four cases of SIH complicated with SDHs were evaluated. Early follow-up neuroimages of these patients revealed that SDHs could be partially or totally absorbed just two to four days after targeted epidural blood patch treatment.

CONCLUSIONTargeted epidural blood patch can result in rapid hematoma regression and good recovery in some patients with a combination of SDH and SIH.

Objective To investigate the effect of intestinal mucosal Toll-like receptor 4/nuclear factor κB (TLR4/NF-κB) signaling pathway on renal damage in pseudo-sterile IgA nephropathy (IgAN) mice. Methods C57BL/6 mice were randomly divided into experimental group (pseudosterile mouse model group), control group (IgAN mouse model group), pseudosterile mouse blank group, and normal mouse blank group. Pseudosterile mice were established by intragastric administration of quadruple antibiotics once a day for 14 days. The pseudosterile IgAN mouse model was set up by combination of oral bovine serum albumin (BSA) administration and staphylococcal enterotoxin B (SEB) injection. The pathological changes of renal tissue were observed by immunofluorescence staining and PAS staining, and the intestinal mucosa barrier damage indicators lipopolysaccharide(LPS), soluble intercellular adhesion molecule 1(sICAM-1) and D-lactate(D-LAC) were analyzed by ELISA. Biochemical analysis was used to test 24 hour urine protein, serum creatinine and blood urea nitrogen. The mRNA and protein levels of Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88) and nuclear factor κB (NF-κB) were detected by reverse transcription PCR and Western blot analysis. Results The kidney damage of pseudosterile IgAN mice was more severe than that of IgAN mice, and the expressions of intestinal mucosal barrier damage markers (LPS, sICAM-1 and D-LAC) were significantly increased in pseudosterile IgAN mice. In addition, the expressions of TLR4, MyD88, and NF-κB level were all up-regulated in the intestinal tissues of IgAN pseudosterile mice. Conclusion Intestinal flora disturbance leads to intestinal mucosal barrier damage and induces activation of TLR4 signaling pathway to mediate renal injury in IgAN.
