Body weight, height, weight index as well as obesity incidence of 4780 people (male 3216, female 1564) aged from 20 to 78 including various kinds of job were investigated in Fusan district in Shandong province. The body weight and height were measured by conventional method. The weight indexwas estimated in terms of the value of weight(kg)/height(cm)2 ? 100. The correlationregression between sex, age, height and weight was calculated as well.The result showed that the average weight index ranging from 0.1933 to 0.2525 in males and 0.1951 to 0-2563 in famales was noticed. Accordingly, the incidence of overweight and obesity was 7.71% and 8.33% in males and 6.96% and 4.73% in females respectively. The correlation coefficients between weight and age (r = 0.9838 within 20-35 in age in males, r = 0.9846 within 20-50 in age in famales), and between weight and height (r = 0.9798 within 144-180cm in males, r = 0.8595 within 140-170cm in females) were highly significant.The data mentioned above were also discussed briefly.

Objective To observe the therapeutic efficacy of the Chinese medical herb decoction qu yin tang combined with narrow-band ultraviolet B (NB-UVB) phototherapy on psoriasis vulgaris, and to investigate its influ-ence on osteopontin (OPN) and vascular endothelial growth factor (VEGF) in serum. Methods Sixty patients with psoriasis were randomly divided into a treatment group and a control group. The treatment group was treated with qu yin tang and NB-UVB; the control group was treated with qu yin tang only. The levels of OPN and VEGF in serum were detected in both groups before and after treatment using an enzyme-linked immunosorbent assay (ELISA). Twenty healthy persons' serum samples were taken as controls. At the same time, any changes in psoriasis area and severity index (PASI) scores in the two groups were recorded and compared. Results After 8 weeks of treatment, PASI scores and levels of OPN and VEGF had been reduced significantly in both groups, and there was a significant difference between the treatment group and the control group. Conclusions Chinese medical herbs combined with NB-UVB phototherapy is a safe and effective method for the treatment of psoriasis. The results suggested that OPN and VEGF may play an important role in the pathogenesis of psoirasis vulgaris.

Objective Studies show that the abnormal ex-pressions of APC and survivin play important roles in the development and progression of colon cancer .Survivin shRNA and APC double gene co-expression lentiviral vector was constructed to observe whether it could be successfully expressed in HT-29 colon cancer cells and whether it could impact on colon cancer cell apoptosis . Methods We selected the best shRNA interference fragment from the construc-tion of three pairs of complementary shRNA fragments and connected it with the effective fragment of APC ( aa1020-1698 ) to construct a double gene co-expression lentiviral vector .HT-29 cells were divid-ed into experimental group , empty loading group and blank group .HT-29 cells were observed by fluorescence microscopy after infec-tion.Survivin and APC expression levels were observed by real time PCR and western blot .Apoptosis was detected by caspase-3 activi-ty assay.

Objective Post-transcription RNA interference (RNAi) is more and more widely applied in multigene therapy.This study aimed to establish an subcutaneous xenotransplanted tumor (SXT) model of human HT-29 colon carcinoma in nude mice and investigate the effects of the survivin shRNA-APC double gene co-expression lentiviral vector on the growth of SXT.Methods Thirty-five nude mice were equally divided into five groups, double-gene survivin shRNA, survivin shRNA, APC, empty vector, and blank, and injected into the left anterior axillary with respective stably transfected cell lines and human HT-29 colon carcinoma cells, all at 2×106/mL, to establish an SXT model of human HT-29 colon carcinoma.The inhibition rate of tumor growth was calculated by measuring the size and weight of the SXT, the expressions of survivin mRNA and protein in the tumor tissue detected by real time PCR and immunohistochemistry respectively, and the apoptosis of the HT-29 colon carcinoma cells determined by TUNEL.Results The mean size and weight of the SXT were significantly reduced in the double-gene survivin shRNA-APC, survivin shRNA, and APC groups as compared with the blank and empty vector groups (P<0.05), though increased in the survivin shRNA and APC groups in comparison with the double-gene group (P<0.05).The expressions of survivin mRNA and protein in the tumor tissue were remarkably lower in the double-gene survivin shRNA-APC, survivin shRNA, and APC groups than in the blank and empty vector groups (P<0.05), even lower in the double-gene group than in the survivin shRNA, and APC groups (P<0.05).The apoptosis rate of the HT-29 colon carcinoma cells was markedly up-regulated in the double-gene survivin shRNA-APC ([56.72±3.17]%), survivin shRNA ([33.64±2.03]%), and APC groups ([31.19±1.79]%) as compared with the blank ([9.89±0.31]%) and empty vector groups ([10.06±0.43]%) (P<0.05), even more significantly in the double-gene than in the survivin shRNA and APC groups (P<0.05).Conclusion The survivin shRNA-APC double gene co-expression lentiviral vector can reduce the expression level the survivin gene, promote the apoptosis of colon carcinoma cells, and suppress the growth of the subcutaneous xenotransplanted tumor.

BACKGROUND:This review explores the current research status and frontier hot spots of functional magnetic resonance imaging(fMRI)in the field of traditional Chinese medicine(TCM)for the treatment of ischemic stroke,and attempts to grasp future research trends,with a view to providing a reference for subsequent research in this field. OBJECTIVE:To visualize and analyze the hotspots and frontiers in the TCM treatment of ischemic stroke based on fMRI using CiteSpace knowledge mapping combined with binary logistic regression equations,in order to grasp the future research trends and further explore the distribution of brain regions with abnormal neural activity related to the types of post-stroke dysfunction. METHODS:CNKI,WanFang,VIP,Chinese Biomedical Literature Database and Web of Science core set database were searched.CiteSpace was used to plot keyword co-occurrence,keyword clustering timeline,burst term detection,co-cited literature mapping to analyze hotpots and frontiers in this field.Binary logistic regression analysis fitted the distribution of brain regions with abnormal neural activity associated with different dysfunction after ischemic stroke. RESULTS AND CONCLUSION:A total of 354 articles were included for CiteSpace knowledge mapping analysis.The number of annual publications showed that the research popularity has been raised from 2000 to 2022 with a good development prospect,but the core strength is mainly concentrated in China.Keywords co-occurrence and clustering time line analysis showed that aphasia,hemiplegia and cognitive impairment are the hot poststroke dysfunction types.Electroacupuncture,acupuncture and head acupuncture are hotspot intervention measures.Functional connectivity is a hotspot analysis method,and resting fMRI is a hotspot scanning technology.The time span of each research hotspot is long,indicating that it has a certain research value and the relevant research is gradually deepening,promoting the research progress in this field.However,acupuncture is the main intervention measure,and there is a lack of research on traditional Chinese medicine,Chinese patent medicine,acupuncture and medicine combination and other TCM therapy.Burst term detection results showed that functional connectivity,graph theory,degree centrality,default mode network,randomized controlled trials have great influence and strong explosive power.They are the current and future frontier hot spots in this field,suggesting that future research should focus on the brain network information integration and strengthen the scientific and rigorous clinical trial design.The results of co-cited literature analysis showed that the epidemiological investigation of ischemic stroke,the safety and effectiveness of acupuncture in the treatment of stroke,the brain activation patterns under different tasks,and the neuropathological mechanism of brain network dysfunction after stroke are the theoretical basis of this field.Future research direction in this field is to explore TCM-targeted brain regions and neural networks to reveal the brain effect mechanism of TCM promoting neural remodeling after stroke.A total of 255 articles were included for binary Logistic regression analysis.The results showed that sensorimotor cortex and premotor area dysfunction are positively correlated with the incidence of motor dysfunction after stroke;hippocampus,cerebellum posterior lobe,precuneus,inferior temporal gyrus and anterior cingulate nerve dysfunction are positively correlated with the incidence of cognitive impairment after stroke;cuneus,angular gyrus and prefrontal lobe neural dysfunction were positively correlated with the incidence of affective disorder after stroke;anterior cingulate,cerebellum posterior lobe neural dysfunction are positively correlated with the incidence of swallowing disorder after stroke.The above brain regions are the core brain regions of the sensorimotor network,default mode network and reward loop,suggesting that functional abnormalities within or between brain networks related to dysfunction may be potential target areas for TCM intervention,but the specific changes in neural activity activation or inhibition still need to be refined.

ObjectiveTo evaluate the clinical efficacy and safety of Notoginseng Radix et Rhizoma powder in treating dyslipidemia by regulating the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway. MethodSixty patients with dyslipidemia （syndrome of combined phlegm and stasis） treated in the Third Affiliated Hospital of Henan University of Chinese Medicine from May 2021 to June 2022 were selected in this study and randomized into two groups according to the randomized， double-blind control principle. The control group was treated with Xuezhikang capsules + Notoginseng Radix et Rhizoma powder placebo and the observation group with Notoginseng Radix et Rhizoma powder + Xuezhikang capsules placebo for 6 weeks. The clinical efficacy， traditional Chinese Medicine （TCM） syndrome scores， and liver and kidney function indicators were evaluated at weeks 0， 3， and 6. Enzyme-linked immunosorbent assay （ELISA） was employed to determine the expression of vascular endothelial growth factor （VEGF）， kinase insert domain receptor （KDR）， epidermal growth factor （EGF）， and epidermal growth factor receptor （EGFR） in the peripheral serum. Quantitative Real-time PCR was employed to measure the mRNA levels of KDR， EGFR， PI3K， and Akt in the mononuclear cells of the peripheral blood. ResultThe observation group （83.33%） showed the total effective rate comparable to that of the control group （89.66%） and no adverse reactions. Compared with before treatment， the patients in the observation group showed decreased TCM syndrome score and serum levels total cholesterol （TC）， triglyceride （TG）， and low-density lipoprotein cholesterol （LDL-C） and after being treated for 3 and 6 weeks （P<0.05）， the level of high-density lipoprotein cholesterol （HDL-C） showed an upward trend, but the difference was not statistically significant. After treatment， the two groups showed no significant differences. Compared with that before treatment, the mRNA expression of PI3K, Akt and EGFR in peripheral blood mononuclear cell and the expression of EGF, VEGF and KDR in serum of the observation group showed a downward trend with time, in which the mRNA expression of PI3K, Akt, VEGF and KDR decreased more significantly (P<0.05)，The expression levels of KDR mRNA and serum EGFR show a trend of first increasing and then decreasing.Compared with the control group after treatment, there was no statistically significant difference in mRNA expression of PI3K, Akt, EGFR, and KDR, as well as serum levels of EGF, EGFR, VEGF, and KDR between the two groups of patients at the same time point. ConclusionNotoginseng Radix et Rhizoma powder is safe and effective in correcting dyslipidemia. It may inhibit the PI3K/Akt signaling pathway by down-regulating the expression of VEGF/KDR to lower the blood lipid level.
