0.05). Conclusion Isthmus is an essential structure to determine the size of femoral component. The dimension of isthmus correlates fairly well with the size of femoral stem. As a measurement to choose the appropriate femoral implant in total hip arthroplasty, the isthmus-method has the similar accuracy as the common templating.
2.Expert consensus on the diagnosis of isolated otolith dysfunction.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2023;37(6):409-414
Isolated otolith dysfunction(iOD) involves a group of unexplained vestibular syndromes that manifest clinically as a sense of translation, tilting or floating, and blurred vision with head movement, with normal semicircular canal function but abnormal otolith function on laboratory vestibular testing. As vestibular medicine has gained widespread popularity in recent years, increasing attention has also been paid to iOD and case reports, clinical studies and diagnostic criteria have been published. However, there is no consensus document to guide the diagnosis of this disease in China. In this context, the Special Committee on Vertigo of China Medical Education Association organized a group of domestic experts in vestibular medicine and formulated this diagnostic consensus after thorough discussion based on the latest evidence in China and abroad, in order to promote the best clinical practice for iOD.

OBJECTIVETo explore the efficacy and effect mechanism of the combined therapy of acupuncture and tapping method in the treatment of obesity and hyperlipidemia of liver qi stagnation and spleen deficiency pattern in the patients.
METHODSOne hundred and four female patients were randomized into a combined therapy of acupuncture and tapping (combined therapy group) group method and an acupuncture group, 52 cases in each group. In the acupuncture group, acupuncture was applied to Qimen (LR 14), Taichong (LR 3), Zhangmen (LR 13), Taibai (SP 3), Zusanli (ST 36), Geshu (BL 17), Ganshu (BL 18), Pishu (BL 20), etc. In the combined therapy group, on the basis of acupuncture treatment, the tapping method with plum blossom needle was used at each acupoint. The treatment was given once every two days, continuously for 3 months in the two groups. The indices were observed, including the obesity indices, such as body mass, body mass index (BMI), body fat percentage (F%) and obesity degree (A); the blood lipid levels such as total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL); the fat-islet axie relevant indices such as fasting plasma glucose (FBS), fasting leptin (FLP), fasting insulin (FINS), insulin sensitive index (ISI), insulin resistance in- dex (Homa IR), insulin secretion index (Homa-β) and autonomic nerve function index (Y value) before and after treatment in the patients of two groups. The efficacy was compared between the two groups.
RESULTSThe total effective rates were 96.2% (50/52) and 84.6% (44/52) in the combined therapy group and the acupuncture group respectively, without significant difference in comparison (P > 0.05). Obesity indices, blood lipid indices, fat-islet axie relevant indices and autonomic nerve function indices were all improved after treatment as compared with those before treatment in the two groups (P < 0.01, P < 0.05), and the improvements in the combined therapy group were much more significant (P < 0.01, P < 0.05).
CONCLUSIONThe combined therapy of acupuncture and tapping method achieves the double effects of weight loss and lipid loss in the treatment of obesity combined with hyperlipidemia. The effect mechanism is possibly related to the positive regulations of blood glucose, lipid metabolism and fat-islet axie in the patients.

Objective To study the accuracy of plasma matrix metalloproteinase-9 (MMP-9) predicting hemorrhagic transformation (HT) in ischemic stroke. Methods The studies on plasma MMP-9 predicting HT in ischemic stroke were included, in which diagnostic criteria, methods, and subjects were clearly described, regardless of language of publication and type of studies. MEDLINE (Apr, 1966 to 2006), EMBase (Apt, 1966 to 2006), CNKI (Feb, 1977 to 2006), and wanfangshuju (1989 to 2005) were searched and the references lists of eligible studies were manually searched. Two reviewers independently evaluated the quality of studies and extracted data. The data were analyzed using the Revman 4. 2 or SPSS 11.0. Results Five trials including 497 patients fulfilled the inclusion criteria, 109 of the 497 patients developed HT. The heterogeneity among studies was great (xspecialty 89. 9% (95% CI: 86. 4%-93.5%), sensitivity 86. 5% (95% CI: 77. 3%-96. 8%). Conclusions The values of plasma MMP-9 may be an independent predictor of hemorrhagic transformation. The number of patients in the included studies is not large enough, and the results need to be confirmed in further studies.

9.Altered expression of Chop and Grp78 in neural tube of rat with spina bifida
International Journal of Pediatrics 2016;43(8):651-653
Chop and Grp78 genes are key genes in endoplasmic reticulum stress(ERS).To explore the gene alteration of Chop and Grp78 in embryo with spina bifida,we studied Chop and Grp78 gene expression by qRT-PCR in neural tube of rat with spina bifida in E12 and primary cultured neuroepithelial stem cells(NEP).We found higher expression of both Chop and Grp78 in neural tube of rat with spina bifida than normal rats.While Chop and Grp78 genes were up-regulated after NEP differentiated into neuron.The up-regulation of Chop and Grp78 genes in neural rube of rat and NEP might be involved in the abnormal apoptosis in spina bifida related with ERS.And we found the primary culture of NEP provided a good model for embryo early development research.

Abstract? AIM: To analysis the relation of severity of rhegmatogenous retinal detachment with the levels of amino acids and vascular endothelial growth factor ( VEGF) in the serum and in subretinal fluid.? METHODS: Forty -eight patients ( 52 eyes ) with rhegmatogenous retinal detachment treated in our hospital were selected.According to the degree of retinal detachment, patients were divided into <1/2 quadrant group, 1/2-3/4 quadrant group and>3/4 quadrant group. Fifty-five healthy objects for physical examination in our hospital were selected as the control group, to compare the differences of amino acids and VEGF levels in the serum.Correlation analysis on VEGF levels and amino acids in the serum and in subretinal fluid among patients with different grades of rhegmatogenous retinal detachment was conducted.? RESULTS: In patients with rhegmatogenous retinal detachment, the tryptophan in serum was 28.59±4.46mg/L, phenylalanine 8.95 ±2.55mg/L, methionine 8.15 ±2.17mg/L, valine 28.62 ±5.29mg/L, histidine 18.96 ±1.85mg/L and VEGF 589.92 ±185.34μg/L, which were higher than those in the control group, and the difference was statistically significant(P<0.05).The levels of phenylalanine was 9.85 ±1.21mg/L, histidine 20.63 ±2.07mg/L and VEGF 718.69 ± 283.34μg/L in the subretinal fluid of>3/4 quadrant group, which were significantly higher than those in the <1/2 quadrant group and 1/2-3/4 quadrant group ( P<0.05). VEGF in the subretinal fluid of VEGF in the rhegmatogenous retinal detachment group were positively correlated with phenylalanine (r=0.542, P<0.001), and histidine (r=0.782, P<0.001).?CONCLUSION: The levels of amino acids and VEGF in the subretinal fluid of patients with rhegmatogenous retinal detachment was higher than those in normals and increased with the severity of retinal detachment.
