Objectives To explore the correlation between the cerebrospinal fluid protein and facial paralysis in pa?tients with Guillain-Barre syndrome (GBS). Methods Clinical and biochemical data of 111 patients with GBS in depart?ment of neurology from January 2005 to September 2015 were retrospectively analyzed. According to facial paralysis, GBS patients were divided into the facial normal and paralysis groups. Their clinical and biochemical characteristics were compared between the two groups. According to level of cerebrospinal fluid protein, GBS patients were divided into cerebrospinal fluid protein normal, mild high and severe high groups. Incidences of facial paralysis were compared among these three groups. The correlation between the cerebrospinal fluid protein and facial paralysis was analyzed. Results There was no significant difference in gender, age, respiratory infection and other clinical symptoms (P>0.05), whereas there were statistically significant differences in cerebrospinal fluid protein, immunoglobulin G, and cerebrospinal fluid albumin/serum albumin ratio between the facial normal and paralysis groups (P<0.05). Among the three groups by differ?ent levels of cerebrospinal fluid protein, there were statistically significant differences in the incidence of facial paralysis (F=3.48,P=0.03). Cerebrospinal fluid protein was positively correlated with facial paralysis (r=0.288,P<0.01). Conclu? sions The incidence of facial paralysis is associated with the levels of cerebrospinal fluid protein. Thus, cerebrospinal flu?id protein may be helpful in monitoring of GBS patients with facial paralysis.

Objective: To evaluate the long-term efifciency of percutaneous transluminal septal myocardial ablation (PTSMA) for treating the patients with hypertrophic obstructive cardiomyopathy (HOCM).
Methods: A total of 66/94 (70.2%) HOCM patients received PTSMA in Shenyang PLA general hospital from 2001-10 to 2012-10 were retrospectively studied. The left ventricular out lfow gradient (LVOFG) was measured at before and after the operation, ECG and echocardiography were examined at 1 month, 6 months and 1 year after operation, and then examined once per year for (63.8±28.5) months.
Results: There were 26 patients lost contact during follow-up period, 40 returned to routine clinical check-up and 2 patients died thereafter, 1 because of sudden death and 1 because of cerebral bleeding. The pre-operative average LVOTG was (102.7 ± 47.5) mmHg, compared with the values at 6 months post-operation and long term (>6 months) after operation (33.9 ± 30.2) mmHg and (29.7 ± 25.4) mmHg,P<0.001. The pre-operative average inter ventricular septal (IVS) was (20.1 ± 3.6) mm, compared with the values at 6 months post-operation and long term after operation (17.5 ± 2.9) mm and (16.4 ± 3.6) mm, P=0.028 andP<0.001. There were 7 patients with NYHA class at II-III and having occasional chest suppression and short of breath. There were no heart transplantation, frequent premature ventricular contraction, tachycardia and other malignant arrhythmia occurred in 38 survivors.
Conclusion: PTSMA may reduce LVOTG, IVS thickness and improve the clinical symptoms in HOCM patients, the long-term efifcacy is reliable.

Thirty-six puerperas who underwent emergency cesarean section at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 24, 2020 to February 9, 2020, who all wore medical surgical masks, were retrospectively included in this study. Anesthesia management was performed under tertiary medical protection measures. A dedicated anesthesia equipment was separately sterilized. Narcotic drugs were used for one patient only, and disposable medical supplies were used for anesthetic supplies. Contact transmission should be avoided when a neonate required resuscitation, and early isolation and nucleic acid testing were provided for the neonates. The rate of suspected cases of novel coronavirus (2019-nCoV) was 11% , and the rate of clinically diagnosed cases was 17% before surgery. The rate of clinically diagnosed cases of 2019-nCoV was 22%, the rate of confirmed cases was 8%, and the total positive rate of diagnosis was 31% after surgery. The rate of neuraxial anesthesia was 86%, the rate of general anesthesia was 14%, the time of spinal puncture was (15±7) min, the time of tracheal intubation under general anesthesia was (2.1±1.3) min, the operation time was (95±36) min, and blood loss was (276±166) ml. The Apgar score of newborns was 8.8 ± 0.5. There was 1 neonate whose mother was diagnosed as having 2019 novel coronavirous disease after operation, an oropharyngeal swab specimen was obtained at 36 h of birth, and the swab was tested positive for 2019-nCoV by nucleic acid testing. As of February 10, 2020, an anesthesiologist involved in the operation was diagnosed to have infection by 2019-nCoV. In conclusion, diagnosis of 2019 novel coronavirous disease during pregnancy is more difficult, it is necessary to perform anesthesia management for cesarean section under tertiary medical protection. Although the difficulty in anesthesia operation is increased under tertiary medical protection, anesthesiologists can carry out standardized anesthesia management and guarantee the safety of maternal and infants and anesthesiologists themselves as long as they are rigorously trained and adhere to protective protocols.

Objective To investigate the mRNA expression of liver receptor homolog 1 (LRH-1) gene in patients with cholesterol gallstone disease so that to elucidate the biomolecular pathogenesis of gallstone for- mation.Methods Twenty-seven patients with cholesterol gallstone (CGS) and 14 controls were included in this study.Biliary composition was assayed and mRNA expression of hepatic LRH 1 gene was determined by real time polymorphism chain reaction.Results In CGS patients,expression of LRH-1 was significantly higher than that in controls (14.18?9.37 vs 7.86?6.19,P＜0.05),and cholesterol of bile was oversaturated (1.17?0.27).Conclusion The formation of CGS may be related to increased expression of hepatic LRH-1 gene.

Objective:Real-time cell-based assay (RTCA) technology was used to detect the influence of compound Danshen tablets with different concentrations on cells to screen outthe sensitive, stable and concentration-dependent cell lines to provide reference for the quality evaluation experiment of cell biological effects of compound salvia miltiorrhiza tablets. Methods:The effects of compound Danshen tablets on human umbilical vein endothelial cells (Huvec), rat cardiac myocytes (H9C2) and rat thoracic aortic smooth muscle cells (RA-VSMC) were investigated by RTCA. The cell index (CI) was measured to form time-dose dependent cell response curves (TCRPs) to screen the the optimal cell lines by description analysis and statistical analysis. Results:All of the three cells show obvious response to the effects of compound Danshen tablets. The sensitivity of RA-VSMC was relatively poor, the range of effective concentrationof three cells was different, and the concentration gradient dependence was also different. H9c2 cells had good sensitivity to compound Danshen tablets, which was gradient dependent, and the effective concentration range wass 0.3-1.8 mg/ml, and it can be used as a cell for quality evaluation of compound Danshen tablets. Conclusions:RTCA technology can monitor and record the growth status of cells in real time. It can accurately reflect the effects of compound Danshen tablets on different cell lines. The data are objective and reliable. It provides a new experimental technology and method for the quality evaluation of compound Danshen tablets.

Objective To investigate the effect of fenofibrate on glucolipid metabolism and insulin sensitivity in lipoprotein lipase heterozygous knockout ( LPL+/-) mice, and to explore its mechanism. Methods LPL+/- mice and wild type ( WT) C57 mice were selected and divided into 3 groups ( n=6 each group):LPL+/-( FB) group, LPL+/-(W)group,andWTgroup.MiceinLPL+/-(FB)groupweregavagedwithfenofibrate(50mg·kg-1·d-1)for8 weeks. Mice in LPL+/-( W) and WT groups were orally fed with the same volume water as that in LPL+/-( FB) group for 8 weeks. Body weight was observed. Plasma triglyceride ( TG ) and free fatty acid ( FFA ) were measured. Intraperitoneal glucose tolerance test in 3 groups of mice were performed. The glucose area under the curve ( AUCG) and homeostasis model assessment for insulin resistance index ( HOMA-IR) were calculated. Insulin-stimulated Ser473 Akt phosphorylation in liver and skeletal muscle was measured by Western blot. Reactive oxygen species ( ROS) levels in liver and skeletal muscle were determined by dihydroethidium staining method and superoxide dismutase ( SOD) and catalase ( CAT) mRNA expression levels were detected by real-time PCR. Results Compared with LPL+/-( W) mice, body weight of LPL+/-( FB) mice was lowered, plasma TG and FFA levels were decreased by about 46.0％and 76.5％respectively, and fasting insulin level and HOMA-IR were decreased while there were no significant differences in fasting glucose level and AUCG between two groups. Insulin-stimulated Ser473 Akt phosphorylation levels in liver and skeletal muscle of LPL+/-mice were enhanced by fenofibrate. ROS level in skeletal muscle of LPL+/-( FB) mice was lower than that in LPL+/-( W) mice while there was no significant difference in ROS of liver between two groups. Fenofibrate significantly increased SOD and CAT mRNA expressions in skeletal muscle of LPL+/-mice, but not in liver. Conclusion Fenofibrate reduces body weight, ameliorates lipid metabolism, and improves insulin sensitivity in LPL+/- mice, with reduced oxidative stress.

Objective:To investigate the correlation between serum insulin-like growth factor 1 (IGF-1), thyroid stimulating hormone (TSH), degree of insulin resistance and thyroid nodule imaging reporting and data system (TI-RADS) grading in patients with type 2 diabetes mellitus (T2DM).Methods:The clinical data of 120 patients with T2DM from February 2020 to November 2021 in Kunshan Hospital of Integrated Traditional Chinese and Western Medicine were retrospectively analyzed. Among them, 56 patients had no thyroid nodules (non-thyroid nodule group), all patients were TI-RADS grade 1; 64 patients had thyroid nodules (thyroid nodule group), including 7 cases of TI-RADS grade 2, 12 cases of TI-RADS grade 3, 20 cases of TI-RADS grade 4, and 25 cases of TI-RADS grade 5. The levels of IGF-1 and TSH were measured by automated biochemical analyzer, the homeostatic model assessment insulin resistance index (HOMA-IR) was calculated. Spearman method was used for correlation analysis; multivariate Logistic regression was used to analyze the independent risk factors of TI-RADS grading in patients with T2DM combined with thyroid nodules; the receiver operating characteristic (ROC) curve was drawn to analyze the efficacy of IGF-1, TSH and HOMA-IR in predicting TI-RADS grading in patients with T2DM combined with thyroid nodules.Results:The IGF-1, TSH and HOMA-IR in thyroid nodule group were significantly higher than those in non-thyroid nodule group: (185.35 ± 45.08) ng/L vs. (168.36 ± 30.25) ng/L, (2.98 ± 0.85) mU/L vs. (2.69 ± 0.35) mU/L and 3.25 ± 0.75 vs. 2.95 ± 0.44, and there were statistical differences ( P<0.05 or <0.01). In patients with T2DM combined with thyroid nodules, with the increase of TI-RADS classification, the IGF-1, TSH and HOMA-IR gradually increased, and there were statistical differences ( P<0.05). Spearman correlation analysis result showed that the levels of IGF-1, TSH and HOMA-IR were positive correlation with TI-RADS grading ( r = 0.918, 0.906 and 0.920; P<0.05). Multivariate Logistic regression analysis result showed that the IGF-1, TSH and HOMA-IR were independent risk factors for TI-RADS grading in patients with T2DM combined with thyroid nodule ( OR = 1.684, 1.044 and 1.851; 95% CI 0.674 to 6.665, 0.032 to 0.055 and 1.212 to 2.298; P<0.01 or <0.05). ROC curve analysis result show that the area under the curve of IGF-1, TSH and HOMA-IR for predicting the TI-RADS grading patients with T2DM combined with thyroid nodule were 0.946, 0.983 and 0.975, with all sensitivity of 100.00%, and specificity of 82.14%, 91.07% and 89.29%. Conclusions:There is a correlation between IGF-1, TSH, HOMA-IR and TI-RADS grading in patients with T2DM combined with thyroid nodule, which has some guiding value for clinical monitoring of thyroid nodule changes.

Laparoscopic proximal gastrectomy (LPG) can be selected for the treatment of early upper gastric carcinoma, but gastroesophageal reflux after operation would seriously affect the quality of life of patients. Esophagogastric anastomosis with double flap technique is a digestive tract reconstruction method using the anastomosis between the esophagus and the anterior wall of the stomach. Compared with other digestive tract reconstruction methods, esophagogastric anastomosis with double flap technique can maintain the postoperative body mass of patients in good condition, improve the nutritional status and the long-term quality of life of patients. Esophagogastric anasto-mosis with double flap technique has good anti reflux effects and retain the possibility of endoscopic examination and treatment. By reviewing literatures at home and abroad, and combined with clinical experiences, the authors discuss current status and digestive tract reconstruction methods of LPG, and deeply investigate the application prospect of esophagogastric anastomosis with double flap technique.
