Objective To observe the clinical efficacy of electroacupuncture plus muscle energy technique (MET) in treating upper crossed syndrome (UCS).Method Forty UCS patients were randomized into a treatment group and a control group, 20 cases in each group. The control group was intervened by electroacupuncture, while the treatment group was treated with MET to relax and regulate the cervical and shoulder muscles in addition to electroacupuncture. The two groups were treated once a day, for 3 weeks in total. The Visual Analogue Scale (VAS), Neck Disability Index (NDI), Hamilton Depression Scale (HAMD) and Pittsburgh Sleep Quality Index (PSQI) were observed before and after the intervention, and the clinical efficacies were compared between the two groups.Result After the treatment, the VAS, NDI, HAMD, and PSQI scores were significantly changed in both groups (P<0.05). The scores of all parameters in the treatment group were significantly different from those in the control group (P<0.05). The total effective rate was 95.0% in the treatment group versus 85.0% in the control group, and the between-group difference was statistically significant (P<0.05).Conclusion Electroacupuncture plus MET can improve the pain, depression, sleep disorder, and the quality of life of UCS patients.

Aim To explore the effects of Yupingfeng polysaccharide(YPF-P)on T cells of adjuvant arthritis(AA)in rats.Methods Freund's complete adjuvant was used to induce AA in rat.Secondary paw swelling of AA rats was measured with volumeter.Peripneral blood lymphocyte proliferation response induced by concanavalin A(ConA)was examined with MTT assay.The CD4+ and CD8+ T cell in peripheral blood were detected by flow cytometer.ELISA method was applied to determine the content of factor IFN-? and radio-immunity assay of factor IL-4.RT-PCR procedures were utilized to determine the expression of IFN-? mRNA.Results 80,160 mg?kg-1 YPF-P could singnificantly inhibit the secondary paw swelling of AA rats.The suppressesion of lymphocyte proliferation of peripheral blood T cell in AA rats was reversed.After treatment by YPF-P,the number of CD4+ cell and the ratio of CD4+/CD8+ markedly decreased.The level of IFN-? in YPF-P treating group was obviously decreased in comparison with that of model control group,while the level of IL-4 was increased.The mRNA expression of IFN-? was inhibited as well.Conclusion Yupingfeng polysaccharide can regulate the turbulence of periphery abnormal T cell subgroups of adjuvant arthritis rats and can recover Th1/Th2 balance to move towards Th1,which may be one of its mechanisms of inhibiting the secondary paw swelling.

Objective To investigate the causes of infant mortality and analyze the reasons of misdiagnosis and medical disputes,and to provide help for improving clinical diagnostic accuracy in future in order to decrease the infant mortality and prevent the occurrence of medical tangle.Methods To collect and reorganize the autopsy pathology reports of medical tangle of infant deaths in the autopsy files of the Pathology Department of Affiliated Hospital of Zunyi Medical College within 5 years from Jan.2008 to Dec.2012,and a total of 58 cases were collected,of whom 39 cases were male and 19 cases were female,and the ages of these cases ranged from 0 to 3 years old.Results In 5 years,the number of medical tangle of infant deaths were 8 cases,10 cases,10 cases,15 cases and 15 cases,respectively,which showed an increasing trend on the whole.Infant mortality showed a significant decrease with the increase of age,as the highest mortality was the baby,which accounted for 77.59％ (45/58 cases) of infant deaths.The most common cause of infant death was pneumonia,which accounted for 15.52％ (9/58 cases) of all diseases,and neonatal asphyxia was the top cause of newborn infant deaths (27.27％,6/22 cases).In the cases of misdiagnosis and missed diagnosis of infant deaths,the respiratory system disease was the most common disease (57.89％,22/38 cases).Conclusions Infant mortality decreased year by year in clinical medicine,but there was an upward trend of medical disputes in infant deaths.Various types of pneumonia was the most common cause of infant deaths,and it was also the main cause contributing to medical tangles of infant deaths.

Objective: To observe the distribution of occupational activity disorders of extremely severe mass burn patients in recovery period after injury. Methods: From December 2014 to December 2015, 65 extremely severe burn patients conforming to the inclusion criteria involved in August 2 Kunshan factory aluminum dust explosion accident were admitted to Kunshan Rehabilitation Hospital. They received comprehensive rehabilitation treatment after burns, including wearing pressure clothes, ultrasound treatment, semiconductor laser and red light irradiation, motor function training, and so on. Over 2 years after injury, a cross-sectional survey was conducted on the patients′ occupational activity disorders. Modified Barthel index (MBI) was used to assess the degree of activities of daily living (ADL) disorder of patients and to grade the independent level of completing each item of MBI, and then the independent level of patients completing self-care MBI items (bathing, dressing, grooming, eating, going to the toilet, urine control, and stool control) was compared with that of mobility items (going up and down stairs, bed and chair transfer, and walking). The Canadian Occupational Performance Measure (COPM) was used to assess the distribution of occupational activity disorders of patients. The distribution of the five most serious occupational activity disorders was counted, then the frequency and probability of which with frequency greater than or equal to 16 times were calculated. Data were processed with Pearson Chi-square test. Results: Over 2 years after injury, the MBI score of patients was (76±22) points, and the ADL of 83.08% (54/65) patients reached completely self-care or light ADL disorder level. The MBI items arranged according to the completing independent level of patients from high to low were urine control/stool control, walking, bed and chair transfer, going up and down stairs, going to the toilet, eating, grooming, dressing, and bathing. The independent level of patients completing self-care MBI items was lower than that of mobility items (χ²=62.298, P<0.001). Over 2 years after injury, the five most serious occupational activity disorders in COPM dimension were mainly concentrated in the self-care dimension, accounting for 55.38% (180/325), followed by 22.46% (73/325) of production activities and 22.15% (72/325) of recreational activities, and the centrally distributed item was the personal self-care item under self-care dimension, accounting for 42.46% (138/325). Over 2 years after injury, the five most serious occupational activity disorders with frequency greater than or equal to 16 times were dressing and undressing, bathing, perineal cleaning, wearing pressure clothes, caring for children, visiting relatives and friends, 31, 25, 16, 17, 18, and 22 times respectively, with a probability of 47.69%, 38.46%, 24.62%, 26.15%, 27.69%, and 33.85% respectively. Conclusions: Over 2 years after injury, most of the patients with extremely severe burns caused by the aluminum dust explosion were completely or basically self-care in their daily life. The disorder of self-care ADL was more serious than that of mobility, and the disorder of individual self-care activity was still the most serious occupational activity disorder of patients in this stage.
