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 investigate the clinical efficacy of intravitreal injection of Lucentis combined with pan retinal photocoagulation and trabeculectomy for neovascular glaucoma(NVG). Methods Seventeen eyes of 15 patients with NVG were treated by 0.5 mg Lucentis intravitreal injection first. Trabeculectomy was performed 7 days later and Pan retinal photocoagulation 2 weeks later. Iris,anterior chamber angle neovascularization,intraocu?lar pressure ,and visual acuity were observed in the following 6 months. Results Iris and anterior chamber angle neovascularization were completely regressed 7 days after the injection in 17 eyes. Six months after photocoagulation, 6 eyes had different degrees of improvement in visual acuity,10 eyes no change in visual acuity and 1 eye decreased from anterior index to immediate manual. There was significant difference in pre?treatment IOP and postoperative IOP( t = 12.75 ,10.26 ,9.73 ,10.77 ,P < 0.01 ). No serious complications were observed after intravitreal injec?tion and trabeculectomy. Conclusions Intravitreal injection of Lucentis could significantly accelerate the regres?sion of iris and anterior chamber angle neovascularization ,which could improve the successful rate of trabeculecto?my and pan retinal photocoagulation. Intravitreal injection of Lucentis combined with trabeculectomy and panretinal photocoagulation is safe and effective for NVG.

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.

BACKGROUND:Recombinant human epidermal growth factor has been shown to promote granulation tissue formation and to accelerate the healing of burn wounds, but the antibacterial effect of recombinant human epidermal growth factor is limited. OBJECTIVE:To investigate the effect of nano-silver dressing combined with recombinant human epidermal growth factor gel in treatment of burns and the influence on the scar. METHODS:A total of 76 cases of shal ow II and depth II degree were randomly enrol ed and assigned to two groups. In the study group, recombinant human epidermal growth factor was coated on the surface of the wound, and then covered by nano-silver dressing. In the control group, recombinant human epidermal growth factor was coated on the surface of the wound, and covered by ordinary sterile gauze. The healing time, the positive rate of bacteria, scarring and adverse reactions were compared between the two groups. RESULTS AND CONCLUSION:The wound healing time and the rate of hypertrophic scars after healing were lower in the study group than in the control group (P<0.01). The rate of flat scar was greater in the study group than in the control group after healing (P<0.01). The bacterial positive rate was significantly lower in the study group than in the control group at 7, 14 and 21 days after treatment (P<0.05). No significant difference in incidence of al ergies and local burning sensation was detected between the two groups (P>0.05). These data confirmed that recombinant human epidermal growth factor gel combined with nano-silver dressing in the treatment of burn has good efficacy and accelerates the wound healing, reduces scar formation, and improves aesthetics.

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.
