Objective To investigate the factors associated with long-term efficacy of microvascular decompression for hemifacial spasm. Methods 253 cases of hemifacial spasm treated with microvascular decompression were followed 13 to 144 months (mean 73 months). Results Hemifacial spasms were obliterated in 232 cases (91.7%) and were partially relieved in 10 cases (4%). However, hemifacial spasm recurred 11 cases (4.3%). We re-operated on those who had recurrent hemifacial spasm and found that the material used for previous decompression had moved. The movement of decompression material could be the cause of spasm recurrence. Conclusions Upholding of depression material around the blood vessels against movement near the facial nerve plays an important role for improving the long-term efficacy of MVD for hemifacial spasm.

Aim To investigate the effect of Jinlida on cholesterol-related genes in skeletal muscle in fat-in-duced insulin resistance ApoE-/ - mice. Methods Ten male C57 BL/6 J mice were selected as normal group ( NF );50 male ApoE-/ - mice with a high-fat feeding after 16 weeks ( HF) were divided into model group, rosiglitazone ( LGLT ) , Jinlida low dose group ( JLDL, 0. 95 g · kg-1 · d-1 ) , Jinlida medium dose group ( JLDM, 1. 9 g·kg-1 ·d-1 ) , Jinlida high dose group (JLDH, 3. 8 g·kg-1·d-1), which were per-formed intragastric administration for 8 weeks. Oil red O staining of mouse skeletal muscle was used for fat ac-cumulation. Insulin receptor ( INSR) , insulin receptor body substrate-1 ( IRS-1 ) , low-density lipoprotein re-ceptor ( LDLR ) , cholesterol sensor ( SCAP ) mRNA and protein expression in mouse skeletal muscle were measured by quantitative reverse transcription PCR ( RT-PCR ) and Western blot. Results Compared with NF group, fasting blood glucose ( FBG) , choles-terol ( TC ) , triglyceride ( TG ) and low density lipo-protein cholesterol ( LDL-C ) of HF mice were signifi-cantly elevated, while high-density lipoprotein ( HDL-C ) significantly decreased ( P < 0. 05 ) . Compared with HF group, Jinlida group could reduce to varying degrees FBG, TC, TG and LDL-C in mice, and in-crease HDL-C ( P <0. 05 ) . Jinlida could downgrade fasting serum insulin ( FINS ) level, and improve the insulin sensitive index ( ISI ) ( P < 0. 05 ) . Jinlida could obviously improve skeletal muscle fat accumula-tion of mice. Compared with NF group, skeletal mus-cle INSR, IRS-1, LDLR mRNA and protein levels of HF group were significantly decreased ( P <0. 05 ) , while SCAP mRNA and protein level increased signifi-cantly (P<0. 05). Compared with HF group, Jinlida could increase to varying degrees INSR, IRS-1, LDLR mRNA and protein levels ( P < 0. 05 ) , and lower SCAP mRNA and protein levels ( P<0. 05 ) . Conclu-sion Jinlida can alleviate fat-induced insulin resist-ance in ApoE-/ - mice through regulation of cholester-ol-related gene expression.

Objective:To study the combined use of endoscopic balloon dilation with endoscopic biliary brushings in diagnosis of bile duct strictures.Methods:A prospective single center study was conducted at the Central Hospital of Wuhan, Tongji Medical College, Huazhong University of Science and Technology. All patients with suspected malignant bile duct strictures shown on CT or MRI imaging from January 2018 to January 2020 were reviewed. All patients gave informed consent to the endascopic retrograde cholangiopancreatography procedures. Their clinical and follow-up data were analyzed. All patients underwent endoscopic balloon dilation of bile duct strictures. Before and after balloon dilation, biliary brush cytology was performed, and the results were used to classify the patients into the control group and the experimental group. Pathological examination of the brush cytology samples was carried out by a single chief pathologist. Presence of cancer cells or significant heterogeneous cells indicated a positive brush cytology test. Negative patients who still highly consider cholangiocarcinoma and agree to surgery and whose gross specimen is confirmed to be malignant after surgery should be considered as false negative by brush examination; it is difficult to judge that patients with cholangiocarcinoma have progress after 2 months of follow-up should be considered as false negative by brush examination. Any progression of disease indicated that the brush test was wrong and the test was again classified as false negative. Only when there was no progression of strictures was the possibility of a benign biliary stricture being considered. The advantage test (McNemar test) was used to analyze the difference between the two diagnostic methods.Results:Of 39 patients who were included in this study, there were 26 males and 13 females, with an age of (68.0 ± 5.2) years. Cholangiocarcinoma was diagnosed by histopathology, surgery or at 2 months follow-up in 35 patients. In the control group, 17 patients had a positive brush test (sensitivity rate was 48.6%, 17/35). In the experimental group, 26 patients had a positive brush test (sensitivity rate was 74.2%, 26/35). In addition, 2 patients in the control group had a positive brush test, while in the experimental group, a negative brush test. A total of 28 patients were positive in the two groups. The sensitivity rate of the brush test was 80.0% (28/35). There were significant differences between the two groups ( P<0.05). Conclusion:Endoscopic balloon dilation combined with endoscopic biliary brushings improved the sensitivity of pathological diagnosis of cholangiocarcinoma, and endoscopic biliary brushings before and after balloon dilation improved the sensitivity of diagnosis.

OBJECTIVE To explore the effect of Lianhuaqingwen capsules ( LHQW ) on junction protein expression in mouse lung tissue of lipopolysaccharide (LPS)-induced acute lung injury ( ALl). METHODS 120 male mice were randomly divided into six groups: normal control, model, model+dexa-methasone 5 mg.kg-1 , model +LHQW 2, 4 and 8 g.kg-1 groups. Dexamethasone and LHQW were administered orally, once daily, for 7 d. 24 h after the last administration, LPS solution was instilled into the tracheas of mice except the normal control group to prepare the mouse model of ALl. 24 h after the establishment of the ALl model, the mice were sacrificed and the pathological changes in the mouse lung tissue were observed by optical microscopy and ultrastructure of alveolar epithelium was observed by transmission electron microscopy. The cell percentage of positive expression of tumor necrosis factor-α(TNF-α) in the peripheral blood T lymphocytes was detected by flow cytometry. The expressions of con-nexin 43 ( Cx43), occludin and zonula occludens protein-1 ( ZO-1) in lung tissues were detected by immunohistochemistry. RESULTS Under the light microscope, the mouse lung of model group showed a large amount of inflammatory cell infiltration and alveolar wall thickening. Compared with model group, inflammatory cell infiltration was reduced in model+dexamethasone, model+LHQW 2,4 and 8 mg.kg-1 groups. Under the electron microscope, the mouse alveolar epithelial cells of model group showed injury. Compared with model group, the damage was reduced in model+dexamethasone, and model+LHQW 2, 4 and 8 mg.kg-1 groups. The cell percentage of TNF-α positive expression in peripheral blood T lympho-cytes in normal control, model, model+dexamethasone, model+LHQW 2,4 and 8 mg.kg-1 groups was (3.6±0.9)%, (6.4±0.8)%, (2.8±0.7)%, (4.7±1.6)%, (4.0±1.5)% and (3.6±1.2)%, respectively. The percentage in model group was obviously higher than that in normal control group( P<0.01), but was lower in the four drug treatment groups than in model group(P<0.05, P<0.01). The expression of Cx43, occludin and ZO-1 in lung tissue of model group was lower than that of normal control group(P<0.01), but higher in model+dexamethasone, model + LHQW 4 and 8 mg.kg-1 groups than in model group(P<0.05). CONCLUSION LHQW may alleviate ALl induced by LPS and play a protective role by inhibiting inflammatory cell infiltration and improving protein connection expression in alveolar epithelial cells and pulmonary vascular endothelial cells.
