Objective:To explore the application effect of an intelligent teaching robot system of lifting manipulation in cervical spine manipulation teaching.Methods:60 doctors were randomly divided into an experimental group ( n = 30) and a control group ( n = 30). The control group was taught by a certified chief physician using a combination of "PowerPoint presentations, video demonstrations, and operation demonstrations" . Each part is 5 min. The experimental group was taught by the intelligent teaching robot system with a spinning technique. The teaching time is 15 min for both groups. At the end of the two teaching sessions, the two groups were trained five times under different BMIs and passed the system assessment. The qualified rates of pre-traction force, lifting and pulling force, maximum force, pre-traction time, lifting and pulling time, rotation amplitude, and pitch amplitude were compared between the two groups. Results:In normal, there was significant differences between the qualified rates of pre-traction force, lifting and pulling force, maximum force, pre-traction time, lifting and pulling time, rotation amplitude, and pitch amplitude in two groups (all P<0.05). For overweight people, there were significant differences in pre-traction force, pulling force, maximum force, and rotation amplitude (all P <0.05), while there were no significant differences in pre-traction time, pulling time, or pitching amplitude (all P >0.05). In obesity, there were significant differences in pre-traction force, lifting and pulling force, maximum force, and pitch amplitude (all P <0.05), but no significant differences in pre-traction time, lifting and pulling time, or rotation amplitude (all P >0.05). Conclusions:The proposed system can improve the pass rate of spinning manipulation, especially by effectively controlling the pre-traction force, pulling force, and maximum force.

The important pathogenesis of knee osteoarthritis (KOA) lies in kidney deficiency and blood stasis. Therefore, Traditional Chinese Medicine (TCM) for tonifying the kidney and activating blood circulation is widely used in clinical practise with high response. The existing literature mainly focuses on single medicine for tonifying the kidney and activating blood circulation, as well as TCM compounds, such as classic prescriptions Yougui Pill, Duhuo Jisheng Decoction, which contain TCMs for tonifying the kidney and activating blood circulation, or self-made empirical prescriptions Bushen Huoxue Recipe and Bushen Tongluo Recipe, which are based on the idea of tonifying the kidney and activating blood circulation. The above TCMs mainly regulate oxidative stress response, inflammatory cytokine level, no level, lymphatic function and microcirculation Inhibit chondrocyte apoptosis, regulate cartilage metabolism, protect and repair cartilage, and inhibit matrix degrading enzymes to play a therapeutic role.

OBJECTIVE: To observe the clinical therapeutic effect of electroacupuncture (EA) combined with tamsulosin hydrochloride sustained release capsule on chronic prostatitis (CP) of damp and heat stasis. METHODS: A total of 70 patients with CP of damp and heat stasis were randomized into an acupuncture plus medication group (35 cases, 4 cases dropped off) and a medication group (35 cases, 5 cases dropped off). In the medication group, tamsulosin hydrochloride sustained release capsule was given orally, 0.2 mg a time, once each night. On the basis of treatment in the medication group, EA was applied at Guanyuan (CV 4), Sanyinjiao (SP 6) and Yinglingquan (SP 9), with disperse-dense wave, 5 mA in intensity for 30 min. Treatment for 30 days was as one course, and totally 3 courses were required in both groups. Before treatment, 1, 2, 3 months into treatment and at the follow-up of 2 months after treatment, the TCM syndrome score and National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) score were observed, and the clinical efficacy was evaluated in both groups. RESULTS: Compared before treatment, the TCM syndrome scores of 3 months into treatment and follow-up were decreased in the acupuncture plus medication group ( CONCLUSION Acupuncture combined with medication can improve the clinical symptoms in patients with CP of damp and heat stasis, and its therapeutic effect is superior to simple western medication.

Objective:To evaluate the clinical efficacy of pulsed radio-frequency(PRF) for knee osteoarthritis(KOA) using Meta-analysis.Methods:The literature of controlled clinical studies on PRF in the treatment of KOA was retrieved, the retrieval databases included China Biomedical Literature Database, The Cochrane Library, PubMed, Web of Science, Medline, Embase, CNKI, Wanfang Database, VIP Database, CBM, EBSCO and Network database. The retrieval period was the time of inception to February 2021. The retrieved literature was screened, quality evaluated and data extracted by two researchers. Statistical analysis was performed using Review Manager 5.3 software.Results:A total of 8 studies were included, including 411 patients with KOA. The 200 patients in the trial group were underwent PRF treatment and the 211 patients in the control group were underwent conventional treatment. Meta-analysis results showed that the experimental group was superior to the control group in terms of knee VAS score, WOMAC score, Lysholm score and effective rate, and the differences were statistically significant (all P<0.05). Conclusions:PRF is more effective in treating KOA than conventional treatment. The quality of the literature research in this study that met the inclusion criteria was low, and a large number of high-quality studies are needed to evaluate the efficacy and safety of PRF treatment.

BACKGROUNDInflammatory demyelinating disease of central nervous system (CNS) is an inflammatory disease characterized by a high childbearing female predominance. Labor-related alterations for postpartum demyelinating attacks are not entirely clear. This study aimed to summarize clinical features of female patients of reproductive age with initial CNS inflammatory demyelinating attacks during puerperium.

METHODSFourteen female patients with initial demyelinating events during puerperium between January 2013 and December 2016 were retrospectively studied. Records of clinical features, neuroimaging, serum antibodies, cerebrospinal fluid (CSF) findings, annualized relapse rate (ARR), and treatment were analyzed.

RESULTSAmong 14 patients, 5 patients were diagnosed with multiple sclerosis (MS), four as neuromyelitis optica (NMO), two as longitudinal extensive transverse myelitis, two as clinical isolated syndrome (CIS), and one as acute brainstem syndrome. All the 14 puerperal female patients presented with more than one manifestation of hemiplegia, paraplegia, uroschesis, visual loss or dysarthria, and with mild to moderate abnormalities of CSF. Attacks occurred during the first trimester postpartum and cesarean section was the main delivery way (n = 10). Median Expanded Disability Status Scale (EDSS) scores were 5.0 (range: 2.0-9.0) at the onset and 2.5 (range: 0-7.0) at the end of follow-ups. Patients with MS and CIS had a significantly lower EDSS scores than patients with NMO spectrum disorders (P < 0.05). Median ARR was 0.46 (range: 0-1.16); all patients had a low ARR (0.49 ± 0.34, 95% confidence interval: 0.29-0.69) with standardized treatments.

CONCLUSIONLabor-related alterations in the mother's immune system might result in newly-onset demyelinating diseases of central nervous system.

To evaluate the promoting blood circulation and removing blood stasis effects of Danshen-Honghua(DH) herb pair with different preparations (alcohol, 50% alcohol and water) on blood rheology and coagulation functions in acute blood stasis rats, and optimize the best preparation method of DH based on principal component analysis(PCA), hierarchical cluster heatmap analysis and multi-attribute comprehensive index methods. Ice water bath and subcutaneous injection of adrenaline were both used to establish the acute blood stasis rat model. Then the blood stasis rats were administrated intragastrically with DH (alcohol, 50% alcohol and water) extracts. The whole blood viscosity(WBV), plasma viscosity(PV), erythrocyte sedimentation rate(ESR) and haematocrit(HCT) were tested to observe the effects of DH herb pair with different preparations and doses on hemorheology of blood stasis rats; the activated partial thromboplastin time(APTT), thrombin time(TT), prothrombin time(PT), and plasma fibrinogen(FIB) were tested to observe the effects of DH herb pair with different preparations on blood coagulation function and platelet aggregation of blood stasis rats. Then PCA, hierarchical cluster heatmap analysis and multi-attribute comprehensive index methods were all used to comprehensively evaluate the total promoting blood circulation and removing blood stasis effects of DH herb pair with different preparations. The hemorheological indexes and coagulation parameters of model group had significant differences with normal blank group. As compared with the model group, the DH herb pair with different preparations at low, middle and high doses could improve the blood hemorheology indexes and coagulation parameters in acute blood stasis rats with dose-effect relation. Based on the PCA, hierarchical cluster heatmap analysis and multi-attribute comprehensive index methods, the high dose group of 50% alcohol extract had the best effect of promoting blood circulation and removing blood stasis. Under the same dose but different preparations, 50% alcohol DH could obviously improve the hemorheology and blood coagulation function in acute blood stasis rats. These results suggested that DH herb pair with different preparations could obviously ameliorate the abnormality of hemorheology and blood coagulation function in acute blood stasis rats, and the optimized preparation of DH herb pair on promoting blood effects was 50% alcohol extract, providing scientific basis for more effective application of the DH herb pair in modern clinic medicine.
