Parkinson's disease (PD) is a commonly encountered central neurodegenerative disease in elderly people. According to theories of traditional Chinese medicine (TCM), PD is characterized by deficiency in the root and excess in the branch. Deficiency was referred to qi-blood deficiency of the liver and kidney. Excess was referred as the wind, fire, phlegm and stasis. Deficiency was the root and excess was the branch. Good efficacies have been obtained by treatment based on syndrome differentiation, treatment with specific prescriptions, acupuncture and moxibustion and comprehensive treatment. Some experiments had been conducted to elucidate its mechanisms. However, no uni-fied standard for therapeutic evaluation, poor control of medicinal quality, inferior quality of designed clinical trials, and unclear treatment mechanism in the clinical study on therapeutic effect of PD treatment with TCM require fur-ther studied.

Objective: To investigate the quality of life and its influencing factors among patients with gestational diabetes mellitus (GDM), so as to provide insights into the improvements in the quality of life among patients with GDM. Methods: GDM patients admitted to Department of Obstetrics and Gynecology, Hangzhou First People's Hospital Affiliated to Zhejiang University Medical School from June 2021 to June 2022 were recruited. Participants' demographics, diagnosis and treatment, sleep quality, depression and social support level were collected. Patients' quality of life was evaluated using the Quality of Life Scale for Pregnant Women with Gestational Diabetes Mellitus, and the factors affecting the quality of life were identified among patients with GDM using a multivariable linear regression model. Results: A total of 300 questionnaires were allocated, and 284 valid questionnaires were recovered, with an effective recovery rate of 94.67%. The respondents had a mean age of (32.81±4.93) years, and the mean scores for the quality of life was (92.63±14.10) points. Multivariable linear regression analysis identified depression (β'=-0.293), sleep disorder (β'=-0.177), insulin therapy (β'=-0.316), regular exercise (β'=0.272) and social support level (medium: β'=0.153; high: β'=0.381) as factor affecting the quality of life among GDM patients. Conclusions GDM patients have a low quality of life. Depression, sleep disorders, insulin therapy, and lack of exercises may cause a decline in the quality of life among GDM patients, and strong social support facilitates the improvements in the quality of life among GDM patients.

OBJECTIVETo explore the clinical effects of Dynesys system combined with posterior lumbar interbody fusion (PLIF) in treating multiple lumbar degenerative disease.

METHODSThe clinical data of 46 patients with multiple lumbar degenerative diseases treated by Dynesys system combined with PLIF from September 2010 to May 2013 were retrospectively analyzed. There were 17 males and 29 females, aged from 38 to 68 years old with an average of (56.38±11.63) years. Operation section was in L2-L5 of 16 patients (6 with fusion of L4,5 and 10 with fusion of L4,5,L5S1) and in L3-S1 of 30 patients (11 with fusion of L5S1 and 19 with fusion of L4,5,L5S1). Patients were followed up for three times: postoperative 3 months, 1 year and final follow-up. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to assess clinical symptoms preoperatively and postoperatively. All patients underwent flexion/extension radiographs examinations before surgery and at final follow-up. Range of motion (ROM) and disc height index (DHI) were recorded.

RESULTSAll patients were followed up from 16 to 48 months with the mean of (23.23±7.34) months. At third follow-up after operation, ODI and VAS of lumbago and leg pain were significant improved than that of preoperative (P<0.01). DHI of fusion segment was significantly increased than that of preoperative (P<0.05). There was no significant difference in adjacent non-fusion segment between preoperative and postoperative (P>0.05). Postoperative ROM of fusion and non-fusion segments were obviously decreased than that of preoperative. There was no significant difference in ROM of upper adjacent non-fusion segment between 3 months and 1 year after operation (P>0.05), but at final follow-up, the ROM was increased (P<0.05).

CONCLUSIONThe preliminary clinical results of the Dynesys system combined with PLIF in the treatment of multiple lumbar degenerative diseases are satisfactory. It can be determined in fusion or non-fusion according to the individual needs and can reserve the some intervertebral motion, prevent the early degeneration of adjacent segments. However, its long-term clinical efficacy should be verified with long time.

Objective: To explore the effect of low-level laser irradiation (LLLI) preconditioning on milieu of infarcted myocardium in experimental rats.
Methods: The myocardial infarction (MI) model was established by left anterior descending (LAD) artery ligation in female rats. 3 weeks later, the qualified MI rats were randomly divided for 3 groups: ① LLLI preconditioning group, the rats received thoracotomy for LLLI by a 635nm, 5mW diode laser with the energy density of 0.96 J/cm2 for 150 seconds, n=26. ② Control group, the rats received thoracotomy for daylight irradiation, n=27. ③ Sham operation group, the rats received thoracotomy without LAD ligation, n=24. The Expressions of myocardial vascular endothelial growth factor (VEGF), glucose-regulated protein 78 (GRP78), superoxide dismutase (SOD) and malondialdehyde (MDA) were evaluate by real time-PCR, Western blot analysis and other relevant laboratory test at 1 hour, 1 day and 1 week after treatment. The myocardial cell apoptosis was examined by TUNEL staining, and left ventricular function was detected by echocardiography.
Results: LLLI preconditioning obviously increased the myocardial VEGF, GRP78 expression and SOD activity, decreased MDA production; while it could not really improve the myocardial cell apoptosis at peri-infarcted area and left ventricular function in experimental rats.
Conclusion: LLLI preconditioning may improve the milieu of infarcted myocardium via decreasing the oxidative stress in experimental rats.

Objective: To explore the effect of omentopexy combining autologous atrial tissue patch cardiomyoplasty for treating the chronic myocardial infarction (MI) in experimental rats.
Methods:The MI model of SD rats was established by left coronary artery ligation. 3 weeks later, the qualiifed animals were randomized into 4 groups for the 2nd operation. ① Control group, the rats only received re-thoracotomy, ② Atrial appendage group, the autologous atrial tissue patch was harvested from left atrial appendage of rats and transplanted to infarcted zone, ③ Omentum group, the omentum of rats was transplanted to infarcted zone through diaphragm and ④ Combination group, the left atrial appendage tissue and omentum were transplanted to infarcted zone together. 4 weeks after the 2nd operation, the cardiac function was evaluated by echocardiography, the size and scar thickness of the infarction were examined by Masson staining, the survival of transplanted atrial tissue and angiogenesis were measured by immunohistochemistry, the protein expressions of VEGF, MMPs and TIMP-3 were examined by Western blot analysis, and the activities of MMPs were
identiifed by gelatin zymography.
Results:4 week after the 2nd operation, transplanted left atrial appendage tissue only survived in Combination group. The areas of infarction were similar among different groups, P>0.05. Compared with Control group, Combination group had the increased scar thickness (329 ± 33)μm vs (391±31)μm, improved LVEF (47.5 ± 4.5)%vs (57.9 ± 5.8)%, improved LVFS (20.7 ± 2.0)%vs (25.2 ± 3.6)%, all P<0.05. Compared with Control group, both Omentum group and Combination group demonstrated higher density of angiogenesis at infracted area (33/0.2) mm2 vs (49/0.2) mm2 and (33/0.2) mm2 vs (48/0.2) mm2, all P<0.01. Combination group had decreased protein expressions of MMPs, while the expressions of TIMP-3 were similar among different groups, the activities of MMP-2 and MMP-9 were decreased by 68%, P=0.002 and 64%, P=0.016 respectively.
Conclusion:Omentopexy could improve the angiogenesis and support the survival of transplanted autologous atrial tissue patch, therefore improve the cardiac function in experimental rats with chronic MI.

This study is to determine the preventive effect and mechanism of targeting IL-17A on pulmonary inflammation and fibrosis after acute lung injury. Mice were treated with anti-IL-17A antibody on the day 7 and sacrificed on the day 14 after bleomycin lung injury. The pulmonary inflammatory status and the deposition of collagen were measured by HE and Sirius stains staining. The contents of hydroxyproline and collagen were measured by using commercial kits. The survival rate of mice was calculated by Kaplan-Meier methods. The inflammatory cytokines in bronchoalveolar lavage fluid were measured by ELISA and the expressions of inflammation-related molecules were detected by Western blotting assay. Targeting of IL-17A could prevent the development of lung inflammation, decrease collagen deposition and the contents of hydroxyproline, and protect against the development of pulmonary fibrosis, which together led to an increase in the animal survival. Moreover, blocking IL-17A decreased the expression ofpro-fibrotic cytokines such as IL-17A, TGF-beta1 and IL-13; increased the expression of anti-fibrotic or anti-inflammatory factors such as IFN-gamma, COX-2, 5-LOX, 15-LOX. Indeed, IL-17A antagonism suppressed the activation of pro-inflammatory p65NF-kappaB but enhanced the activation of pro-resolving p50NF-kappaB. In conclusion, that blockade of IL-17A prevents the development of pulmonary fibrosis from acute lung injury, is because blocking IL-17A may prevent acute inflammation converting to chronic inflammation.

Objective: To conifrm the omentopexy decreasing the susceptibility of ventricular arrhythmia in experimental rats with chronic myocardial infarction (MI) by nerve remodeling.
Methods: The MI model of SD rats was established by left coronary artery ligation. 3 weeks later, the qualiifed animals were randomized into 3 groups for the 2nd operation. ① Sham operation group, the rats received the 2nd operation without ligation, ② Isolated MI group, the rats received the 2nd operation without omentopexy, ③ Omentopexy group, the rats received the 2nd operation with omentopexy. n=20 in each group. 4 weeks after the 2nd operation, the electrophysiological characteristics were assessed by relevant techniques, the new and sympathetic nerves in MI border zone were examined by immunohistochemistry, the protein expressions of connexin43 and nerve growth factor (NGF) were measured by western blot analysis and the cardiac endothelin-1 (ET-1) level was evaluated by ELISA.
Results: Compared with Isolated MI group, Omentopexy group showed decreased susceptibility of arrhythmia (3.5 ± 1.2) vs (0.9 ± 0.2), improved electrical transduction (1.5 ± 0.2) mV vs (3.4 ± 0.3) mV and decreased capture threshold (5.5 ± 0.3) mV vs (2.2 ± 0.2) mV, all P<0.05. Compared with Isolated MI group, immunihistochemisty indicated that Omentopexy group had decreased new and sympathetic nerves in MI border zone, as for GAP43:(1388.4 ± 244.9)μm2/mm2 vs (768.6 ± 144.1)μm2/mm2, for TH:(1552.4 ± 270.3)μm2/mm2 vs (1018.5 ± 124.7)μm2/mm2, all P<0.05. Western blot analysis showed that Omentopexy group had the lower NGF expression and higher connexin43 expression;ELISA demonstrated that Omentopexy group had the lower ET-1 expression, P<0.05.
Conclusion: Omentopexy may decrease the susceptibility of ventricular arrhythmia after MI in experimental rats, which might be related to the cardiac nerve remodeling.
