ObjectiveTo systematically analyze the effect of therapeutic exercise on neck function and quality of life in patients with neck pain and forward head posture. MethodsRandomized controlled trials about the effects of exercise training on forward head posture and neck pain were searched from PubMed, Web of science, Embase, Medline, Science Direct, EBSCO, Springlink, CNKI, VIP, and Wanfang Data from database establishment to April, 2022. The literature was screened by two researchers independently. Cochrane bias risk assessment tool and Physiotherapy Evidence Database Scale were used to evaluate the quality of the included articles. Revman 5.4 software was used for meta-analysis. ResultsA total of 416 patients from eleven literatures were included. Level 1a evidence indicated scapula stability training could effectively improve cranial vertebral angle (MD = 3.62, 95%CI 2.41 to 4.83, P < 0.001), and relieve pain (MD = 1.32, 95%CI 0.18 to 2.46, P = 0.02). Level 1b evidence indicated scapula stability training could reduce functional disability (MD = -0.92, 95%CI -1.11 to -0.74, P < 0.001). Level 1b evidence indicated deep cervical flexor training could improve cranial vertebral angle (MD = -0.83, 95%CI -1.56 to -0.10, P = 0.03), relieve pain (MD = 0.93, 95%CI 0.54 to 1.32, P < 0.001), and improve neck functional disability (MD = 2.17, 95%CI 1.39 to 2.95, P < 0.001). ConclusionScapula stability training and deep cervical flexor training can effectively improve cranial vertebral angle, relieve neck pain, and improve neck function.

Objective:To assess the efficacy of non-pharmaceutical intervention on improving sleep quality in pregnant women by network Meta-analysis.Methods:Randomized controlled clinical trials on non-pharmaceutical intervention to improve sleep quality in pregnant women were searched on Cochrane Library, PubMed, Web of Science, Embase, China Biology Medicine disc, CNKI and Wanfang Database by computer, and the search time limit was from the establishment of databases to December 2022. Two researchers independently screened the literature, extracted data and evaluated the risk of bias in the included studies. Stata 14.0 software was used to conduct a network meta-analysis.Results:Finally, a total of 26 randomized controlled trial were included, including 2 363 patients and 7 non-pharmaceutical intervention measures. The best probability ranking results of network meta-analysis showed that in terms of total score evaluation of Pittsburgh Sleep Quality Index, relaxation intervention, traditional Chinese medicine treatment, psychological intervention, exercise intervention, music therapy, sleep health education and routine nursing were ranked from high to low. In terms of dimensional evaluation of Pittsburgh Sleep Quality Index, relaxation intervention, traditional Chinese medicine treatment, psychological intervention and music therapy had better effects.Conclusions:Current evidence suggests that relaxation intervention, traditional Chinese medicine treatment, psychological intervention and music therapy may be more effective interventions in improving the sleep quality of pregnant women.

ObjectiveTo explore the effect of exercise on the postural control and muscular function around the ankle in patients with functional ankle instability (FAI) with meta-analysis. MethodsRandomized controlled trials about therapeutic exercise for FAI published before December, 2021 were searched from PubMed, EBSCO, SPORTdiscus, Medline, Science Direct, Springlink, Web of Science, Embase CNKI, VIP and Wanfang Data. The quality and evidence grades of the researches were evaluated by two researchers, and the outcomes were analyzed with RevMan 5.4. ResultsFourteen randomized controlled trials were finally included, involving 434 subjects. Compared with no exercise intervention, therapeutic exercise might significantly improve the movement of center of pressure whether with eye-open or eye-closed (eye-open, SMD = -0.28, 95%CI -0.46 to -0.09, P = 0.003; eye-closed, SMD = -0.24, 95%CI -0.40 to -0.09, P = 0.001); while therapeutic exercise might also enhance the activation of the peroneus longus before dynamic task (SMD = 0.38, 95%CI 0.05 to 0.71, P = 0.03), and activation of the peroneus longus (SMD = 0.53, 95%CI 0.16 to 0.90, P = 0.005) and tibialis anterior (SMD = 0.47, 95%CI 0.10 to 0.84, P = 0.01) after dynamic task. There was neither significant difference in the activation of the tibialis anterior (SMD = 0.48, 95%CI -0.14 to 1.11, P = 0.13), nor the peak torque ratio of eversion to inversion isokinetic strength (SMD = -0.15, 95%CI -0.46 to 0.16, P = 0.340) before dynamic task between the two groups. ConclusionTherapeutic exercise can decrease movement of center of pressure, enable anticipatory contraction of peroneus longus before dynamic tasks and compensatory contraction of peroneus longus and tibialis anterior after tasks, to make it easier to deal with external interference, maintain articular stability and prevent re-injury.

Objective: To investigate nutritional quality of school lunch in some primary schools and middle schools in the Pearl River Delta, and to provide the scientific basis for improving the nutritional quality of students lunch and formulating scientific and effective interventions. Methods: Five-day lunch meal survey by chemical analysis were conducted, and students lunch at school were recorded by meal review in three age groups from 8 primary and middle schools in the Pear River Delat area. The energy and nutrient content were obtained and compared with the reference intake of dietary nutrients of student. Results: The average protein intake at lunch of all age groups had reached the recommended standard (80%-95%), the energy supply ratio of carbohydrate in the range of 38.3%-42.3%, the energy supply ratio of fat in 63% school meal exceeded the recommended standard. Vitamin A, vitamin B 1, vitamin B 2, calcium, iron and other nutrients were seriously inadequate; while sodium intake far exceeded the recommended standard. Conclusion The main nutrients of school lunch of primary and middle school in Pearl River Delta can basically meet the growth and development needs, but there are still some deficiency and unbalanced diet nutrient content which are lower than the recommended intake. It is recommended to strengthen nutrition education of catering enterprises and school to improve the scientific combination of diets.

Objective To explore the effects of dietary approaches to stop hypertension (DASH) on the quality of life and re-hospitalization rate in patients with chronic heart failure (CHF). Methods A total of 163 patients with CHF receiving standard medical therapy in the Cardiology Department of the First Affiliated Hospital of Zhengzhou University from February to September 2014 were selected and divided into experimental group (n=85) and control group (n=78) randomly. Low salt, low fat diet was applied in the control group, while DASH was adopted in the experimental group. Patients' body mess index (BMI), blood pressure, blood glucose, blood lipid, ejection fraction, cardiac function, the score of Minnesota Living with Heart Failure Questionnaire (MLHFQ) and re-hospitalization rate were compared before and after intervention. Results There were no statistical differences in BMI, blood pressure, blood glucose, blood lipid, cardiac function and the score of MLHFQ before intervention (P> 0.05). Patients' BMI, systolic pressure, cholesterol and triglyceride of the experimental group paitents were all lower than those of the control group 12 months after intervention, with statistical significance (P< 0.05). 12 months after intervention, patients' quality of life of the experimental group was higher than that of the control group (P<0.05), and the re-hospitalization rate was lower than that of the control group (P<0.05). Conclusions DASH can improve the quality of life in patients with CHF, reduce readmission rate, thus improving the prognosis of heart failure.

Objective To investigate the characteristic of movement disorders,so as to improve their diagnosis and treatment. Methods The clini?cal data of patients with movement disorders that admitted in the dystonia and Botox outpatient department were analyzed. Results Cases of involun?tary movement were significantly more than the primary dystonia,and case of primary hemifacial spasm was dominant(163 cases,61.05%). Among the 66 cases of primary dystonia,blepharospasm was ranked the first(19 cases),the second was spasmodic torticollis(18 cases),and the third was Meige syndrome(12 cases).There was no statistical significance in the gender distribution among primary hemifacial spasm,blepharospasm,spas?modic torticollis and Meige syndrome. Instead,there was statistical significance in the treatment methods(P<0.05),and there was statistical signifi?cance in the mean treatment and onset age(P<0.05). Of the 163 cases with primary hemifacial spasm,the mean onset age was 44.22±12.22 years, and the ratio of men to women was 1∶2.4. There were statistical significances in the mean onset age and duration among the patients with different severity degrees(all P<0.05). Conclusion Primary hemifacial spasm,blepharospasm,spasmodic torticollis and Meige syndrome are the com?mon disease in outpatient department. The primary hemifacial spasm is dominant,women are more than men,and the onset age and/or duration are proportional to the severity degree.

Objective To investigate the clinical and imaging characteristics of bilateral medial medullary infarction. Methods The clinical data of 3 patients with bilateral medial medullary infarction admitted to Shengjing Hospital of China Medical University were analyzed retrospectively. The related literature was reviewed. Results Three patients in this group were all males. Their main clinical manifestations were quadriplegia, dysarthria, and paresthesia, and 1 of them complicated with respiratory failure. One patient was suspected of having Guillain-Barre syndrome. The hyperintensities of heart-shape,Y- shape,and V- shape were its imaging features of typical MRI diffusion weighted imaging. Conclusion Bilateral medial medullary infarction is a rare posterior circulation ischemic lesion in clinical practice. Its early symptoms are not typical and easy to be misdiagnosed and missed. MRI diffusion weighted imaging is its main imaging examination method.

Objective To evaluate the clinical value of tumor chemosensitivity test in the guidance of the advanced epithelial ovarian carcinoma patients treated with chemotherapy.Methods Women with ovarian cancer were enrolled and fresh tissue samples were collected for chemoresponse testing.Oncologists chose a drug for each patient according to the patient’ s condition by double blind method.Each treatment was classified by the assay as: sensitivity (S); moderate sensitivity (I);resistant (R).Progression-free survival (PFS) and overall survival (OS) were detection.The relationship between treatment response and PFS or OS was analysis.Results 262 patients were enrolled.The PFS and OS were significantly improved in sensitivity patients (S) after chemotherapy,but no significant difference were found in I and R groups.In I+R groups (HR=0.66,P=0.008) , median PFS was 8.9 months, OS was 5.8 months.Chemotherapy response test results was consistent with clinical results cisplatin sensitive and resistant ( HR:0.72 vs.0.66).Multi factor regression analysis showed that tumor chemosensitivity test was independent prognostic factors (HR =0.66, P =0.021).The average OS extended for 14 months (37.6 months for the S group vs.group I +R 23.8 months,HR =0.62, P =0.011).Conclusion Tumor chemosensitivity assay is correlated with the clinical effects and might play an important role in guiding the recurrent epithelial ovarian cancer patients with individualized chemotherapy.

Objective To observe the consistency of T-cell receptor (TCR) genes mutation in lymphocytes in rats after irradiation in vivo and in vitro.Methods A total of 48 female rats were randomly divided into 6 equal groups.Peripheral blood samples from them were collected to separate the lymphocytes and then irradiated to X-ray irradiation with the dose rate of 200 cGy/min at the doses of 0,0.5,0.75,1.0,2.0,and 3.0 Gy,respectively.Then all the lymphocyte samples were cultured for 7 days.Flow cytometry with direct immunofluorescence was used to detect the TCR gene mutation.The levels of TCR gene mutant frequency (TCRMF) of different groups were calculated.Results The TCRMF levels of different groups after irradiation in vivo and in vitro all displayed a dose-dependent manner and there were no significant differences in the TCRMF between different dose irradiation groups(t = -1.1-0.3 ,P ＞0.05).Conclusions A consistency of TCRMF after irradiation in vivo and in vitro is proven.The results of TCRMF of peripheral blood lymphocytes irradiated in vitro by flow cytometry can precisely reflect the TCR genes mutation after whole-body irradiation.
