Objective To analyze the correlation of traditional Chinese medical constitution types withcardiovascular risk factors in community hypertension patients. Methods We defined the constitution types of 1108 community hypertension patients, created personal health archives and provided routine examination for the subjects. After that, we input and analyzed the relevant data and results by computer. Results In 1108 cases of hypertension patients, 229 (20.67%) were defined as harmony physique, 879 (79.33%) as biased physique. In patients with biased physique, phlegm-dampness physique accounted for 25.54% (283 cases) , and then came yin deficiency physique and Qi deficiency physique, which accounted for 15.16% (168 cases) and 13.18% (146 cases) , respectively. The biased physique was dominated by single biased physique with a total of 590 cases ( 67.12%) , but the complex physique was also in large quantity, with a total of 289 cases ( 32.88%) . The complex physique consisting of two kinds of single physique was commonly seen in the patients with complex physique, accounting for 15.70%. The complex physique consisting of more kinds of single physique had less percentage. Phlegm-dampness physique was a kind of physique involving the most cardiovascular risk factors. Patients with phlegm-dampness physique had higher incidence of overweight, abnormal lipid level, family history of cardiovascular disease, lack of physical exercise and electrocardiographic abnormality, and the difference was statistically significant compared with other physique types ( P<0.05 or P<0.01) . Conclusion Phlegm-dampness, yin deficiency and Qi deficiency physique are the three commonly-seen constitution types in hypertension patients. Phlegm-dampness physique is the most commonly-seen biased physique and is also a kind of physique involving the most cardiovascular risk factors. Prevention and management in consideration with the constitution characteristics and cardiovascular risk factors will be a new prospective method for the treatment of hypertension patients in community.

Objective:To investigate the clinical significance and the diagnostic value of detecting kidney injury biomarkers in urine and serum of children with Henoch-Sch?nlein purpura nephritis (HSPN).Methods:A total of 216 children with untreated HSPN, who were admitted in Beijing Children′s Hospital of Capital Medical University from January 2018 to December 2019, were recruited in this retrospective study. Two hundred and sixteen healthy children were selected as the healthy control group. We determined the levels of six biomarkers of kidney injury, including transferrin (TRF), immunoglobulin (IgG), microalbumin (mAlb), alpha-1 microglobulin (α1-MG), N-acetyl-β-D-glucosaminidase (NAG) in urine and cystatin C (CysC) in serum. The data from the two groups were analyzed, the diagnostic value of each biomarker was evaluated and a logistic regression model for the diagnosis of HSPN was established. In addition, 60 children with HSPN, who were admitted to our hospital from November 2021 to February 2022 and 60 healthy children, who underwent healthy check up in the same period were included to validate the diagnostic performance of the established logistic model. Receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of each biomarker.Results:The urine levels of TRF, IgG, mAlb, α1-MG and NAG and the serum level of CysC were significantly higher in the HSPN group than those in healthy control group (all P<0.05). The area under the ROC curve (AUC) of TRF, IgG, mAlb, α1-MG, NAG and the serum levels of CysC was 0.749, 0.719, 0.810, 0.648, 0.828 and 0.790 (all P<0.05). Logistics regression analysis showed that IgG, mAlb and TRF were the three diagnostic determinants of HSPN ( OR=1.083, 1.105, 1.704,all P<0.001), and the AUC was 0.916 of the established logistic model based on these three biomarkers. The sensitivity was 87.4% and the specificity reached 96.2%. The logistic model was validated by independent cohorts, and the AUC was 0.973, the sensitivity was 95.0% and the specificity was 98.3%. Conclusions:The levels of urine TRF, IgG, mAlb, α1-MG, NAG and serum CysC were higher in children with HSPN. The established logistic regression model based on three biomarkers including IgG, mAlb and TRF in this study has satisfactory clinical value in diagnosing HSPN in children.

The researches on the acupoint effect specificity were summarized to explore whether the integrality of the acupoint effect specificity existed and analyze the connection between the relativity and integrality of the acupoint effect specificity. The literature on the clinical and experimental researches relevant with the acupoint effect specificity was retrieved through CNKI from January 2007 to October 2017. A total of 39 papers met the retrieving criteria. Separately, in terms of the holism of TCM theory, the holism of meridian theory and modern research, the integrality of acupoint effect specificity was analyzed. The relativity and the integrality are indicated in the acupoint effect specificity. The integrality of acupoint effect specificity is closely related to the holism of TCM theory as well as the meridians. Just because of its integrality, the acupoint effect specificity is relative, rather than absolute.

OBJECTIVETo compare the effects of electroacupuncture (EA) at "Dachangshu" (BL 25) or "Tianshu" (ST 25) for visceral sensitivity, gene expression product c-kit of colonic Cajal interstitial cells (ICC) and capsaicin receptor 1 (TRPV1) of irritable bowel syndrome (IBS) rats, so as to investigate the effect and mechanism differences of EA at the back point and the front point of large intestine for IBS rats.
METHODSForty-two Wistar neonatal rats were randomly divided into a blank group (9 rats) and a model group (33 rats). IBS model was established with mother and child separation, acetic acid enema in young rats and colorectal dilatation method. Twenty-seven IBS rats in life were randomly divided into a model control group, a Dachangshu group and a Tianshu group, 9 rats in each group. EA (disperse-dense wave, 2 Hz/100 Hz, 0.1-0.3 mA) for 20 min was used at "Dachangshu" (BL 25) and "Tianshu" (ST 25) respectively in the Dachangshu and Tianshu groups, once every other day, totally 5 times. The rats in the model control group were fixed with soft cloth sleeve for 20 min, without acupuncture. No intervention was used in the blank group. The stool property Bristol grading score was recorded before and after intervention in each group. The visceral sensitivity was evaluated by abdominal withdrawal reflex. The latency until the first systolic wave occurred and the number of systolic wave within 90 s were observed. Immunohistochemical was used to detect the positive expressions of c-kit and TRPV1, the ICC colon specific marker.
RESULTSCompared with the blank group, the Bristol score increased,latency period shortened, systolic wave number increased, c-kit and TRPV1 positive expressions increased in the model control group (all <0.01). Compared with the model control group, the Bristol score decreased, latency period increased, systolic wave number decreased, c-kit and TRPV1 positive expressions decreased after intervention in the Dachangshu and Tianshu groups (<0.05, <0.01). Compared with the Dachangshu group, the TRPV1 positive expression decreased after intervention in the Tianshu group (<0.05).
CONCLUSIONEA at "Dachangshu" (BL 25) or "Tianshu"(ST 25) can improve the diarrhea in IBS model rats, reduce the visceral sensitivity, and its mechanism may be related to regulating the expressions of colon c-kit and TRPV1. EA at "Tianshu" (ST 25) is more apparent for TRPV1 than at "Dachangshu" (BL 25).
