The "brain electric field" therapy is a novel electroacupuncture method created by Professor GAO Weibin to treat cerebral infarction in the recovery period. This therapy is suitable for the treatment of motor disorders, sensory disorders, cognitive disorders, hemianopsia and bulbar paralysis during the recovery period of cerebral infarction. Based on the different symptoms, the corresponding brain functional areas are selected, supplemented with Taiyang 2, Tunyan 2, Tiyan, Gongxue and Xiatianzhu. These points are attached to electric acupuncture apparatus, and stimulated with dense wave, at frequency of 50 Hz and tolerable intensity. This therapy presents a remarkable effect on cerebral infarction in the recovery period, providing the new approach to the treatment of this disease.

OBJECTIVE To assess the effi-cacy and safety of acupuncture-related treat-ments for postherpetic neuralgia(PHN),identify the most effective acupuncture and related treat-ments.METHODS PubMed,Cochrane Central Register of Controlled Trials,Embase,Web of Science,and four Chinese databases,a clinical research registration platform,and grey literature were searched.We evaluated the risk of bias and quality in the included studies and per-formed a Bayesian multiple network meta-analy-sis.RESULTS We included 29 randomized con-trolled trials comprising 1973 patients,of which approximately 17.24%showed a high risk of bi-as.According to the Jadad scale,2,16,and 11 studies were high,medium,and low quality,respectively.The pairwise meta-analysis results revealed that the efficacy of all acupuncture-related treatments for pain relief related to PHN showed the difference was statistically significant com-pared with that of antiepileptics.The network meta-analysis results showed that pricking and cupping plus antiepileptics were the most effec-tive,followed by electroacupuncture(EA)plus antiepileptics for pain relief in patients with PHN.EA plus antiepileptics ranked the best regarding reduced Pittsburgh Sleep Quality Index and Self-Rating Depression Scale scores in patients with PHN.No results were found regarding total response rate or quality of life among this study.Acupuncture-related treatments showed a lower incidence of adverse events than that of antiepi-leptics-related treatments.CONCLUSION Acu-puncture-related therapies may be potential treat-ment options for PHN and are relatively safe.Pricking and cupping plus antiepileptics are the most effective techniques for pain relief.EA plus antiepileptics is the best approach for improving insomnia and depression symptoms of PHN.

Acupuncture at Baliao points for urinary incontinence has the advantages of obvious therapeutic effect, simple operation and few complications, which is mainly used for the treatment of urinary incontinence after stroke, urinary incontinence after spinal cord injury, stress urinary incontinence and urinary incontinence of bladder overactivity, etc. Urinary incontinence after stroke and spinal cord injury is a complication of disease, most of which are combined with acupuncture at Baliao points on the basis of primary disease treatment. The bladder meridian of foot-Taiyang has the characteristics of "entering the collateral brain" and "carrying spine to the waist". Baliao points can conduct induction along the bladder meridian to the sick site along the bladder meridian, and can play a certain therapeutic role in the treatment of the primary disease. Stress urinary incontinence and urinary incontinence of bladder overactivity can be regarded as independent diseases. Since Baliao points are located in the lumbosacral region which is close to the bladder, acupuncture can play a role in the near treatment of acupoints, improve the operation of bladder qi and blood, and the curative effect has a cumulative effect.

Objective: To observe the impact of mind-regulating acupuncture plus donepezil on the cognitive ability, mean cerebral blood flow velocity, event-related potential P300, and activities of daily living (ADL) in the aged patients with Alzheimer disease (AD).Methods: Sixty senile AD patients were divided into a treatment group and a control group following the envelope method for random allocation, with 30 cases in each group. Based on the conventional treatment of the internal medicine, the control group received oral donepezil, and the treatment group received oral donepezil plus mind-regulating acupuncture. After 4-week treatment, the two groups were evaluated by the mini-mental state examination (MMSE), Alzheimer disease assessment scale-cognitive part (ADAS-Cog), and ADL; changes in P300 and the mean cerebral blood flow velocity were also observed.Results: Before treatment, there were no significant differences in the scores of MMSE, ADAS-Cog, or ADL between the two groups (P>0.05). The MMSE score increased after treatment in both groups and was notably higher in the treatment group than in the control group, showing intra-group and inter-group statistical significance (P<0.05). After treatment, the ADAS-Cog and ADL scores dropped in both groups and were markedly lower in the treatment group than in the control group, also showing intra-group and inter-group statistical significance (P<0.05). Compared with the same group before treatment, the latency of P300 was shortened and the amplitude was extended in both groups, all with statistical significance (P<0.05); the latency was shorter and the amplitude was larger in the treatment group than in the control group after treatment, presenting significant between-group differences (P<0.05). The mean blood flow velocity accelerated after the intervention in both groups, and the differences were statistically significant (P<0.05); the improvement in the treatment group was more notable than that in the control group (P<0.05).Conclusion: Mind-regulating acupuncture plus donepezil can regulate the latency and amplitude of P300, increase cerebral blood flow, and improve the learning and memory abilities of AD patients.

Objective:To observe the epidemiological characteristics and transmission chain of COVID-19 in Harbin, and to provide epidemiological evidence for improving the COVID-19 preventive measures and optimizing prevention and control strategies.Methods:The epidemic situation of COVID-19 in Harbin in January 2021 was analyzed by using the Infectious Disease Report Information Management System and the Public Health Emergency Management Information System of the China Disease Prevention and Control Information System, the epidemic situation information publicly released by the Heilongjiang Provincial Health Commission, and the epidemiological report of Heilongjiang Province Certer for Disease Control and Prevention and Harbin Center for Disease Control and Prevention. The main transmission chains were sorted out through combination of epidemiological field investigation, serological testing, gene sequencing, big data and other means.Results:From January 12 to February 4, 2021, 295 cases of COVID-19 infection (including confirmed cases and asymptomatic infections) were reported in Harbin, which affected 6 districts of Harbin and were concentrated in 41 of the 274 townships in the city. The sex ratio of male to female was 1.00∶1.12 (139∶156); the age ranged from 1 to 86 years old, and the median age was 45 years old. The proportion of confirmed cases and asymptomatic infection was 1.00 ∶ 1.02 (146 ∶ 149), and there was a significant difference in the distribution of different ages between them ( P = 0.042). The cases were mainly found through the health screening of the centralized isolation personnel (178 cases, 60.3%). Other detection methods included active screening (87 cases, 29.5%), screening of the home isolation personnel (26 cases, 8.8%), and medical treatment in medical institutions (4 cases, 1.4%). The main transmission chain of the outbreak was the case associated with a food processing enterprise, with a total of 259 cases, accounting for 87.8% of the total cases. The gene sequencing results showed that the case sequence was homologous with that of Wangkui County, Suihua City, Heilongjiang Province. Conclusions:A food processing enterprise is involved in the main transmission chain, which indicates that the epidemic prevention and control measures needs to be further optimized. Specifically, the supervision and management of food processing enterprises, cold chain storage companies and other enterprises should be strengthened. High attention should be paid to the hidden dangers of COVID-19 in large and medium sized enterprises with hermetic space in Harbin.

Objective:To explore the arsenic trioxide (As 2O 3)-induced apoptosis of human neuroblastoma cells (SH-SY5Y cells) and the protection mechanisms of folic acid (FA) and vitamin B 12 (VB 12). Methods:SH-SY5Y cells were cultured in vitro and divided into six groups by group design: control group (normal cultured), arsenic exposed group (10.00 μmol/L As 2O 3), FA intervention group (0.30 mmol/L FA + 10.00 μmol/L As 2O 3), VB 12 intervention group (0.06 mmol/L VB 12 + 10.00 μmol/L As 2O 3), combined intervention group (0.30 mmol/L FA + 0.06 mmol/L VB 12 + 10.00 μmol/L As 2O 3) and reagent control group (0.30 mmol/L FA + 0.06 mmol/L VB 12). Cells in each group were cultured for 24 h ( n = 3). Flow cytometry was used to determine the apoptosis rate of cells in each group. Transmission electron microscopy was used to observe the ultrastructural changes of the cells. The expression levels of mRNA and protein of apoptosis-related indicator B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X (Bax) were detected by fluorescence quantitative PCR and Western blotting. The activity of cysteinyl aspartate specific proteinase (Caspase) 3 was detected by luminescent assay. The above indicators were statistically analyzed. Results:There was statistically significant difference in the apoptosis rate among different groups ( F = 213.036, P < 0.05). The apoptosis rate in arsenic exposed group [(44.43 ± 3.54)%] was higher than that in control, FA intervention, VB 12 intervention, and combined intervention groups [(1.80 ± 0.06)%, (14.37 ± 0.13)%, (19.10 ± 1.56)%, (17.11 ± 2.34)%, P < 0.05]. Under transmission electron microscope, the apoptotic bodies, mitochondria swelling and degeneration, chromatin agglutination were observed in SH-SY5Y cells exposed to arsenic. The morphological and organelle changes of SH-SY5Y cells were significantly improved after respective and combined intervention of FA and VB 12. The expression levels of Bcl-2, Bax mRNA and protein were significantly different among different groups ( F = 5.178, 7.169, 6.142, 9.194, P < 0.05). The expression level of Bcl-2 protein in arsenic exposed group was lower than that in control group ( P < 0.05), and the expression levels of Bax mRNA and protein were higher than those in control group ( P < 0.05). The expression levels of Bcl-2 mRNA and protein in FA intervention group and combined intervention group were higher than those in arsenic exposed group ( P < 0.05), and Bcl-2 mRNA expression level in VB 12 intervention group was higher than that in arsenic exposed group ( P < 0.05). The expression levels of Bax mRNA and protein in FA intervention, VB 12 intervention and combined intervention groups were lower than those in arsenic exposed group ( P < 0.05). There were statistically significant differences in Caspase 3 activity among different groups ( F = 84.604, P < 0.05). Caspase 3 activity in arsenic exposed group was significantly higher than those in control, FA intervention, VB 12 intervention, and combined intervention groups ( P < 0.05). Conclusions:Arsenic exposure can lead to apoptosis and ultrastructural changes of SH-SY5Y cells. FA and VB 12 may effectively inhibit apoptosis through regulating Bcl-2/Bax pathway and decrease Caspase 3 activity, thus playing a protective role on nerve cells.

【Objective】 To analyze the cause of single-ELISA reactive of four blood screening items in 18 blood stations in Henan, so as to provide the basis for improving the quality of blood screening. 【Methods】 The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP of 18 blood station laboratories in Henan throughout 2019 was calculated, and the causes were analyzed according to different ELISA reagent combinations and gray area settings in each laboratory. 【Results】 The overall single-ELISA reactive rates of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP were 1.740(2 154/1 237 789), 0.564‰(698/1 237 789), 1.421‰(1 759/1 237 789) and 1.561‰(1 932/1 237 789), respectively, showing significant differences by detection items (P <0.05). Person correlation analysis showed that the single-ELISA reactive rate was independent of the gray area settings.but dependent on laboratories and reagent combinations. The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP in D laboratory was the highest and higher than that in other labs using the same reagent.The laboratories with high HBsAg single-ELISA reactive rate were mostly those using a combination of imported reagents and domestic reagents, including the top 6 laboratories. The laboratories with high anti-HCV single-ELISA reactive rate were mostly those using certain domestic reagents. No obvious rules was noticed by single-ELISA reactive for anti-HIV. Laboratories with high anti-TP single-ELISA reactive rate were mostly those using combination 4. 【Conclusion】 The HBsAg single-ELISA reactive rate was the highest in the four blood screening items of blood station laboratories in Henan. The single-ELISA reactive rate is related to the laboratory itself and the reagent manufacturer, suggesting that laboratory quality control should be strengthened and proper reagent combination should be selected to reduce the waste of blood.
