Nontraumatic convexal subarachnoid hemorrhage is a rare type of nonaneurysmal subarachnoid hemorrhage.Its etiologies and clinical manifestations are diverse.This article reviews nontraumatic convexal subarachnoid hemorrhage from the aspects of etiology, clinical manifestation, imaging, diagnosis, treatment, and prognosis.

Based on clinical research and information-sharing system, this article was aimed to study both the syndrome distribution and Chinese medicine composition of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in the COPD base of our hospital using the complex networks. The analysis was made on the common rules of syndrome distribution and features of key Chinese medicine compositions in the diagnosis and treatment of AECOPD. The clinical research and information-sharing system was used on the AECOPD data study (3000 hospital electronic medical records from August 2012 to January 2015). Data was processed by ETL software. The database was constructed. And the complex networks were used in the data mining. The results showed that the distribution of AECOPD common syndromes was heat-phlegm obstructing lung of 41.94%, phlegm-turbid obstructing lung of 22.97%, phlegm-damp obstructing lung of 10.30%,qi-yin deficiency of 6.31%, phlegm-stasis obstructing lung of 5.72%, lung-kidneyqi-deficiency of 4.01%, lung-spleenqi-deficiency of 1.15%, and phlegm obstructing orifices of 1.15%. Chinese medicine compositions were obviously divided into two large groups, which were the core Chinese medicine group and the associated Chinese medicine group. The research results illustrated that the clinical research and information-sharing system had good analysis and classification effects, which not only analyzing the medication laws of senior Chinese medicine experts and single disease treatment by a hospital, but also using in the large data analysis (data collection of single or multiple diseases on Chinese medicine clinical research nationally). It provided a good scientific research platform for Chinese medicine.

Objective: To observe the effect of reinforcing and reducing manipulation by breathing on yin and yang meridian points for motor function of knee joints in patients with ischemic stroke. ＜br> Methods: A total of 60 ischemic stroke cases were randomly allocated into an observation group and a control group, 30 in each group. Other than basic and conventional rehabilitation therapies, cases in the observation group were treated with reinforcing and reducing manipulation on yin and yang meridians points for a period of 8 weeks; whereas cases in the control group only received the same basic and conventional rehabilitation therapy as that in the observation group. Then the knee joint energy, support moment and shaking moment were compared between the two groups before treatment, and after 4-week and 8-week treatment respectively. ＜br> Results: Before treatment, there were no between-group significant differences in knee joint energy, support moment and shaking moment (all P>0.05). After treatment, the knee joint energy, support moment and shaking moment in both groups were significantly improved (P＜0.05). After 8 weeks of treatment, the knee joint energy, support moment and shaking moment in both groups were significantly improved than that of 4-week treatment (P＜0.05). In addition, there were between-group statistical significances in comparing knee joint energy, support moment and shaking moment after 4 and 8 weeks of treatment (P＜0.05). ＜br> Conclusion: Reinforcing and reducing manipulation by breathing on yin and yang meridian points can increase the knee joint support and shaking force and moment in stroke patients and improve their walking ability.

Objective To observe the change of extension-flexion arc of ankle in hemiplegia due to ischemic stroke after yin-yang acupuncture associated with respiration needling manipulations.Method Sixty ischemic stroke patients were divided into a control group and a treatment group by random number table, 30 in each group. The control group was intervened by basic treatment, while the treatment group was by yin-yang acupuncture associated with respiration needling manipulations in addition to the basic treatment. Before intervention and 28 d after intervention, the Lokomat gait analysis system was adopted to observe the change of the extension-flexion arc of ankle respectively under motorial and stationary states.Result When heel was grounded, the flexion angle, the maximum extension-flexion arc value, and motility of ankle joint of the treatment group were statistically different from those of the control group (P＜0.05).Conclusion Yin-yang acupuncture associated with respiration needling manipulations can effectively improve the movement and the walk function of hemiplegia due to ischemic stroke.

This study was aimed to investigate the therapeutic effect of yin-yang meridian acupuncture by reinforc-ing-reducing with patient's respiration on lower limb function among post-stroke patients. A total of 100 stroke pa-tients were enrolled and randomly divided into two groups, which were the control group and the treatment group, with 50 cases in each group. Basic treatment was given in the control group with no related rehabilitation treatment. Basic treatment was given in the treatment group combined with yin-yang meridian acupuncture by reinforcing-re-ducing with patient's respiration. All patients were assessed with kinematics time parameters at the beginning of the treatment and 28 days after the treatment on muscle strength, muscular tension and the change of joint movement of hip joint and knee joint among patients. The results showed that compared with the control group, there was significant difference in treatment group on muscle strength, muscular tension and the change of joint movement of the hip joint and knee joint 28 days after the treatment (P < 0.01). It was concluded that yin-yang meridian acupuncture by reinforcing-reducing with patient's respiration can effectively increase the muscle strength, reduce muscular tension, and improve the change of joint movement, in order to increase the lower limb movement func-tion among stroke patients.

Objective To observe the effect of yin-yang acupuncture in association with respiratory reducing-reinforcing needling manipulations on the gait cycle in patients with post-stroke hemiplegia. Methods Sixty patients with ischemic stroke were randomized into a treatment group and a control group, 30 each. The control group was intervened by conventional medication, while based on which the treatment group was additionally given yin-yang acupuncture in association with respiratory reducing-reinforcing needling manipulations. The kinematic time parameters were evaluated before intervention and after 28-day treatment. Results After intervention, the stance phase of the affected side and the healthy side, ambulation cycle, swinging phase of the affected side and the healthy side, and the stance phase of both limbs in the treatment group were significantly different from that in the control group(P＜0.05). Conclusion Yin-yang acupuncture in association with respiration reducing-reinforcing needling manipulations can effectively improve the gait cycle and ambulation function of the patients with post-stroke hemiplegia.
