Objective:To explore whether the deqi effect affects the effectiveness of manual acupuncture for treating knee osteoarthritis by a network meta-analysis (NMA).Methods:Eight databases were searched for relevant published studies since inception through January 2021.Randomized control trials that compared manual acupuncture with deqi,manual acupuncture without deqi,and conventional treatment of western medicine were included.Languages were limited to English and Chinese.Two authors independently selected eligible studies,assessed methodological quality and the effects of deqi,and extracted outcome data.The mean difference (MD) and standardized mean differences (SMDs) with 95％ confidence intervals (CIs) were calculated by Stata 15.0 to conduct an NMA based on a frequentist framework.Results:Fourteen trials with a total of 1868 subjects were included.The direct and indirect comparisons were authentic,according to inconsistency tests.The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pooled results indicated that there was no significant effect of deqi(SMD =-0.23,95％ CI[0.81,0.35]).The pooled results of visual analogue scale (VAS) were similar to those of WOMAC (MD-0.53,95％ CI[1.03,0.02]).Conclusion:As a summary of the currently available research,the NMA results indicated that deqi effect might not be the crucial factor for the effectiveness of manual acupuncture.

Lung is one of the most sensitive target organs of human beings under the shock waves. Due to its serious injury, rapid development and high mortality, blast lung injury has been a widely concerned research topic in the field of military medicine. In the normal physiological state, the body is in a dynamic balance between pro-inflammaton and anti-inflammation, oxidation and anti-oxidation, promoting apoptosis and inhibiting apoptosis. While blast lung injury breaks the balance and causes physiological, biochemical and pathological changes in the body, seriously leading to acute respiratory distress syndrome and multiple organ dysfunction syndrome, and eventually the mortality. So far, the researches on blast lung injury mainly involve damage model, pathogenesis, pathological changes, intervention treatment and so on, which has achieved great research findings. In the review, the authors summarize the progress of molecular mechanism for blast lung injury from the perspective of inflammatory reaction, oxidative stress, apoptosis and so on, which may promote the discovery of new targets for the diagnosis, treatment and rehabilitation intervention of blast lung injury.

Objective To investigate the expression of guanylate binding protein 5 (GBP5) and ArfGAP with SH3 domain ankyrin repeat and PH domain 1 (ASAP1) genes in pulmonary tuberculosis patients and tuberculosis latent population. Methods Forty pulmonary tuberculosis patients (pulmonary tuberculosis group), 40 latent tuberculosis infection patients (latent tuberculosis infection group) and 40 cases of healthy control (healthy control group) were selected from August 2016 to May 2017. The gene expression was detected in 4 ml peripheral anticoagulant blood by real-time fluorescent quantitative reverse transcription-polymerase chain reaction (RT-PCR) and the relative expression of two genes in three groups were compared. Results The GBP5 gene expression in three groups was significantly differentce (F=7.23, P=0.001). The GBP5 gene relative expression in pulmonary tuberculosis group was significantly higher than that in latent infection group :1.58 ± 0.80 vs. 1.09 ± 0.68, there was significant difference (t=2.93, P=0.004). The GBP5 gene relative expression in pulmonary tuberculosis group was significantly higher than that in healthy control group: 1.58 ± 0.80 vs. 1.04 ± 0.61, there was significant difference (t=3.40, P=0.010). The GBP5 gene relative expression in latent infection group and healthy control group had no significant difference (t=0.39, P=0.700). There was no significant difference in ASAP1 expression among three groups (F=0.26, P=0.770). Conclusions The expression of GBP5 in pulmonary tuberculosis patients, latent tuberculosis infection patients and healthy controls is different, and GBP5 could screen latent tuberculosis infection patients which is expected to be a potential screening marker for latent tuberculosis infection.

OBJECTIVETo discuss the effects on detrusor hyperreflexia treated with ginger-salt-isolated moxibustion at "Shenque" (CV 8) and its mechanism.

METHODSThirty female adult SD rats were selected. The model of detrusor hyperreflexia was prepared with complete spinal transection at T, of which, 20 rats were randomized into a model group (10 rats) and a moxibustion group (10 rats). A sham-operation group (10 rats) was set up for sham-spinal transection. In the moxibustion group, when urine incontinence occurred (about in 2 weeks of modeling), the ginger-salt-isolated moxibustion at "Shenque" (CV 8) was given, 3 moxa cones each time, once a day, continuously for 7 days. After treatment, in each group, the urodynamic parameters were determined, after which, the bladder detrusor was collected. Western blot was used to determine the protein expressions of M2 and M3 receptors.

RESULTSCompared with the sham-operation group, the micturition interval was shortened apparently (<0.01); the maximal bladder pressure was increased apparently (<0.01); the protein expression of M2 receptor in the detrusor was increased significantly (<0.05) and that of M3 receptor had no apparent change (>0.05) in the rats of the model group. Compared with the model group, the micturition interval was longer apparently (<0.01), the maximal bladder pressure was reduced apparently (<0.01), the protein expression of M2 receptor in the detrusor was reduced significantly (<0.05) and that of M3 receptor had no apparent change (>0.05) in the rats of the moxibustion group.Compared with the sham-operation group, the results of the above indicators were not different significantly in the moxibustion group (all>0.05).

CONCLUSIONSThe ginger-salt-isolated moxibustion at "Shenque" (CV 8) suppresses the overactive bladder in the rat with spinal transection and its effect mechanism is possibly relevant with reducing the protein expression of detrusor M2 and inhibiting the excessive contraction of the detrusor.

Objective To investigate the apoptosis and toxicity of oncolytic virus H101 combined with radiation on apoptosis of A549 lung adenocarcinoma cells. Methods A549 lung adenocarcinoma cells in exponential growth phase were divided into four groups: control ( PBS) group, radiation ( IR) group, oncolytic virus (H101) group and radiation combined with oncolytic virus (IR+H101) group. The cells were double dyed with Annexin fluorescein isothiocyanate ( V-FITC/PI ) and then the apoptosis ratio of cells in every group was detected by the flow cytometry. The cytotoxic effect of cells in every group was detected by lactate dehydrogenase ( LDH) release test. The mRNA expression of oncolytic viruses H101 capsid protein Hexon was detected by real-time fluorescence PCR ( RT-PCR) to compare the oncolytic virus replication in each group. Results Cell apoptosis rate in H101 group (55. 37%) was significantly higher than that in PBS group (1.03%) (t =36.51, P <0.05). Cell apoptosis rate in IR + H101 group (93. 06%) was significantly higher than that in H101 group (55. 37%), IR group (12. 67%) and PBS group (1. 03%) (t=13. 51, 24. 14, 38. 99, P<0. 05). LDH releasing percentage in IR group and H101 group at different time after virus transfection was significantly higher than that in PBS group ( t=25. 84,39. 38, 32. 51, 78. 18, P<0. 05;t=31. 40, 2. 68, 23. 43, 60. 98, P<0. 05). LDH releasing percentage in IR+H101 group was significantly higher than that in PBS group (t=80. 71, 119. 74, 109. 80, 123. 94, P<0. 05), IR group (t=28. 80, 54. 34, 72. 34, 61. 91, P<0. 05) and H101 group (t=42. 02, 57. 45, 57. 01, 58. 83, P<0. 05). Compared with H101 group at the same time point, the mRNA expression of Hexon in IR + H101 group at 24, 48 and 72 h was increased by 16. 26, 28. 37 and 39. 58 times, respectively (t=54. 50, 33. 73, 29. 28, P<0. 05). Conclusions The oncolytic virus H101 plays a role of radiosensitization in tumor cells. Radiation also increases the replication of the oncolytic virus H101 and thereby enhances the oncolytic effect of the oncolytic virus H101. Therefore, oncolytic virus H101 combined with radiotherapy has synergistic effect on killing tumor cells.

Objective To observe the effects of acupuncture on oxidative stress and neuronal damage in the prefrontal cortex of chronic cerebral hypoperfusion (CCH) rats; To investigate the molecular mechanisms of acupuncture in cognitive impairment of vascular dementia (VD) rats. Methods The animal model of VD was replicated by permanent bilateral common carotid artery occlusion (2VO) to induce CCH in rats. After modeling, rats were randomized into model group, acupuncture group and non-acupoint group. Sham-operation group was set as control group. Rats of acupuncture group and non-acupoint group were treated with needling for 2 weeks at 3 days after 2VO. Nissl and DHE staining were respectively used to evaluate the numbers of neurons and ROS level. SOD activity was examined by xanthine oxidase technique. Results Compared with sham-operation group, the number of neurons and SOD activity decreased in the model group, while the ROS level increased. Compared with the model group, the number of neurons and SOD activity increased in the acupuncture group, while the ROS level decreased. There were no obvious changes in all indexes in non-acupoint group. Conclusion Acupuncture can inhibit oxidative stress and improve neuronal damage and loss in the prefrontal cortex of VD rats.

Objective To investigate the expression of insulin-like growth factor 1 (IGF-1), insulin growth factor receptor 1(IGF-1R)and insulin growth factor receptor 2(IGF-2R)in colorectal cancer, and their relationship with the relevant clinicopathological factors. Methods Immunohistochemical SP method was used to detect the expression of IGF-1,IGF-1R and IGF-2R in 154 cases of colorectal cancer tissues,58 cases of benign disease tissues (colorectal adenoma, polyps) and 90 normal tissues. Results The positive rate of IGF-1 and IGF-1R expression in colorectal cancer tissues [93.5%(144/154), 70.1%(108/154)] was higher than that in benign diseases [51.7%(30/58), 51.7%(30/58)] and adjacent normal tissues [18.9%(17/90), 35.6%(32/90)] (P=0.001). The positive expression rate of IGF-1 and IGF-1R in colorectal cancer tissue, benign disease tissue and adjacent normal tissues decreased gradually, and there was significant difference between any two groups (P<0.05). The positive expression rate of IGF-2R had no significant difference between any two groups (P>0.05). IGF-2R was significantly different between any two groups (P<0.05). The expression of IGF-1R and IGF-2R in colorectal cancer tissues were not significantly correlated with gender, location, tumor size, family history, depth of tumor invasion and local lymph node metastasis (all P>0.05).IGF-1 was positively correlated with the body mass index(r=0.169,P=0.036).IGF-2R was negatively correlated with age (r=-0.196, P=0.015), and positively correlated with TNM staging in patients with colorectal cancer (r=0.227, P=0.005). The expression of IGF-1 was positively correlated with IGF-1R (r=0.281, P=0.000 1). There was no significant correlation between IGF-1 and IGF-2R in cancer tissues (P>0.05). Conclusion IGF-1 and IGF-1R may promote the occurrence of colorectal cancer, and IGF-2R may be associated with the progress of colorectal cancer,and obesity is a risk factor for incidence of colorectal cancer.
