Objective To investigate the correlation between plasma brain natriuretic peptide (BNP) ,central aortic systolic pres-sure with the degree of coronary artery lesion .Methods One hundred and fifty patients with coronary artery disease ,positive coro-nary angiographic results and without heart failure in the cardiological department of this hospital from March to June 2011 were selected and divided into the hypertension group (n=90) and the non-hypertension group(n=60) according to the blood pressure . The plasma BNP before angiography was detected by ELISA .The coronary lesion vessels and clinical scores were assessed after an-giography .The central aortic pressure before angiography was measured by the noninvasive measurement method and the diastolic blood pressure(DBP) ,systolic blood pressure(SBP) and pulse pressure(PP)were recorded .The correlation between PP and BNP was analyzed by Logistic regression .Results The plasma BNP concentration in the hypertension group was significantly higher than that in the non-hypertension group(P<0 .05) .The SBP level in 2 vessels ,3 vessels was significantly higher than that in the momal coronary group(P<0 .05) ,the PP in 3 vessels was significantly higher than that in the momal coronary group (P<0 .05) . The BNP level in 3 vessels ,2 vessels and single vessel of coronary artery lesion was significantly higher than that in the normal cor-onary artery group(P<0 .05) .The Logistic regression analysis on the PP influencing factors found that PP was closely related with the number of coronary artery lesion vessels ,lesion score ,LVEF and BNP ;the multiple correlation coefficient between PP with the number of coronary artery lesion vessels ,lesion score and BPN was 0 .91 ,its linear model was PP=0 .543 lesion vessels number +0 .656 lesion score + 0 .864 BNP .Conclusion PP of the central aortic pressure is a risk factor for the development and progress of coronary artery stenosis occurrence .BNP may be used as a plasma marker of the degree of coronary artery stenosis .

0.05).The effective rates of patients with recurrence or metastasis were respectively 92%(12/13) and 7/9.The rate of acute radiation reaction of the rectum between the treatment group and control group were respectively 46%(13/28)and 80%(24/30),with a significant difference(P0.05),while the rate of severe bone marrow depression between two groups showed a significant difference(0 and 13%,P 0.05).Conclusion The therapeutic effect of 3DCRT is similar to that of traditional radiotherapy in the treatment of cervical carcinoma,but the former treatment method has a lower rate of acute complications.

Objective To understand the prevalence of depressive symptoms and associated sexual characteristics among men who have sex with men (MSM) in Foshan,Guangdong province.Methods Respondent-driven sampling method was used to recruit MSM who were 18 years and older,living in Foshan longer than 6 months.Scales of depression,demographical information,and characteristics of sexual behaviors were collected using a self-designed questionnaire.Respondent-Driven Sampling Analysis Tool and SAS were used to generate crude and estimated population proportion as well as 95％ confidence intervals (CI).Multivariate logistic regression was performed to explore potential factors associated with depressive symptoms.Results Among 249 respondents,the mean age (standard deviation) was 31.9 (8.5) years,with 43.5％ of them having had 7-9 years of education while 25.9％ had 10-12 years.49.7％ of the respondents were currently married.56.7％ of them had bisexual orientation.42.3％ of them met their sex partners in parks/toilets and 63.3％ of them had their first sex with a female.The estimated prevalence of depressive symptoms was 34.8％(28.2-42.3) among MSM in Foshan.Younger age,lower education levels,only had oral sex,and regularly meetingr sexual partners in parks were associated with depressive symptoms,with the adjusted odd ratio (95％ CI) as 3.31 (1.39-7.86),2.23 (1.01-4.93),3.09 (1.10-8.70) and 2.38(1.20-4.75),respectively.Conclusion Depression related symptoms might associate with the demographical and sexual characteristics of MSM in Foshan,suggesting that psychological interventions should involve components as demographical and sexual characteristics.

Objective The factors influencing the dose distribution of intracavitary brachytherapy for moderately advanced and advanced uterine cervical cancer was studied.Methods Ninty-five patients with cervical cancerⅡ～Ⅲb who received radical radiation therapy in our department from Aug,2004 to Nov,2005,were treated with after-loading brachytherapy using,first,the self-designed“Mutipurpose Hori- zontal Transit Table”(MPHTT) for locating and treatment before the intracavitaray brachytherapy proper. The deviation of isodose curve based on A-B reference system,and the dose of deviation was defined by measuring in a practical standard phantom.Results There were significant influence on the deviation of i- sodose curve in pathology and para-metrial infiltration of cervical cancer and operating skill,but negative to clinical stage.The degree of deviation of isodose curve could not be lowered with the increase in sessions of intracavitary brachytherapy.Conclusions It is necessary to perform the locating,by use of mphtt,before the proper brachytherapy for patients with cervical cancer,not only for the identification of the deviation of i- sodose curve,but also to provide the evidence for revising the plan for dose adjustment of conformal radiation therapy in the pelvic cavity.

Objective To analyze the acupoint selection rules of acupuncture for the treatment of tic disorders in children based on data mining techniques.Methods A computerized search was conducted for the clinical research literature on acupuncture treatment of tic disorders in children included in the CNKI,Wanfang,VIP,SinoMed,and PubMed databases from January 1992 to December 2022.A database was established by Excel 2019 to count the commonly used treatment methods and analyze the high-frequency application methods acupuncture(high-frequency acupoints,channel entry of acupoints,acupoint association rules,and acupoint clustering),auricular point seed-pressing(high-frequency auricular points,and acupoint association rules),and the high frequency division of cluster needling of scalp point.Results A total of 190 valid literature articles were included,involving 270 acupuncture prescriptions;among them,184 acupoints were counted in the acupuncture method,with a total application frequency of 1 906 times,and the high-frequency application of the acupoints in descending order were Baihui(DU20),Taichong(LR3),Fengchi(GB20),Hegu(LI4),Sanyinjiao(SP6),Neiguan(PC6),Shenmen(HT7),Zusanli(ST36),Yintang(EX-HN3),Sishencong(EX-HN1);and the high-frequency meridians were governor vessol,foot taiyang stomach meridian,foot taiyang stomach meridian,foot shaoyang gallbladder meridian,hand taiyang large intestine meridian,foot taiyang bladder meridian,foot jueyin gallbladder meridian;three sets of strong association rules and five clusters of acupoints were analyzed by SPSS modeler 18.0 and IBM SPSS Statistics 26.0 software.There were 29 acupoints of auricular point seed-pressing,application total frequency was 206 times,high-frequency application of auricular points in descending order of Shenmen(HT7),liver,heart,subcortex,kidney;four groups of acupoint strong association rules were obtained through the analysis of SPSS modeler 18.0 software.A total of 14 zones were involved in the application of cephalic acupoint plexus zoning,of which the high-frequency zones were parietal anterior temporal diagonal,parietal parietal 1,and chorea tremor control zone.Conclusion Acupuncture treatment of tic disorders in children,according to its pathogenesis(liver hyperactivity,kidney depletion,spleen deficiency,phlegm disturbance,etc.)and tic site,select acupoints compatibility,and mostly choose yang meridian acupoints,which is related to the nature and treatment characteristics of wind pathogen.Children's tic disorders are closely related to emotional disorders,therefore acupuncture and auricular acupoints all emphasize the method of soothing the liver and clearing the heart,and regulating the emotional state.Cluster needling of scalp point mostly used parietal temporal anterior oblique line,parietal 1 line,and dance tremor control area for the treatment of tic disorders.For children,auricular point seed-pressing and cluster needling of scalp point has the minimun of pain,the effect of treatment is long,and it is not easy to have dangerous situations such as bent needle,broken needle and so on.

OBJECTIVEThis study aimed to explore the scene-trait coping style of military rescuers in Wenchuan earthquake in an effort to provide scientific evidences for mental intervention program for Chinese military personnel.

METHODSBy cluster sampling, a total of 151 military rescuers and 331 control servicemen were administered the military personnel scene-trait coping style scale (MPSTCSS).

RESULTSAll active coping factor scores, and passive coping factor scores of affection, health and economy in the rescuer group were significantly higher than those in control group (P < 0.05). The 21-above age subgroup, the 3-year plus service subgroup, and the officer subgroup had significantly higher active coping factor scores on military tasks, military experience and personal development than those of the 21-below age subgroup, 3-year minus service subgroup and the soldier subgroup, respectively (P < 0.05 or P < 0.01).

CONCLUSIONThe earthquake relief servicemen can cope with stressful situations better than control group by taking active coping style. The officers, servicemen older than 21 years, and servicemen with more service duration than 3 years could usually take active coping style.

OBJECTIVETo study the effect of salvianolic acid B (SAB) and curcumin, the extracts of Salvia Miltiorrhiza and Curcuma Longa, on the proliferation and activation of hepatic stellate cell (HSC), and the extracellular signal regulated kinase (ERK) expression in it.

METHODSRat's HSC-T6 were cultured and treated by SAB or curcumin. The inhibitory effect on cell proliferation was determined by 3-(4, 5-dimthyl-2-2thiazoly)-2, 5-diphenyl-2H-tetrazolium bromide (MTT) colorimetry, and the expression levels of alpha smooth actin (alpha-SMA), collagen type I, and ERK were determined by Western blot.

RESULTSSAB and curcumin inhibited the proliferation and activation of rat's HSC-T6 in dose-dependent fashion and significantly reduced the expression level of alpha-SMA (P < 0.01). Curcumin significantly reduced the expression of collagen type I (P < 0.05). Both SAB and curcumin showed insignificant effect on the ERK expression level, but they could significantly reduce the level of phosphorylated-ERK expression, showing significant difference as compared with that in the control group (P < 0.01 and P < 0.05 respectively).

CONCLUSIONSAB and curcumin could significantly inhibit the proliferation, activation of HSC, and the production of type I collagen in HSC, the mechanism may be associated with their inhibition on ERK phosphorylation.

OBJECTIVETo study the the relationship between lymphatic vessel density (LVD) and distal intramural spread (DIS), and evaluate the value of LVD in determining the length of distal resection in low rectal cancer.

METHODSNinety-two samples from patients undergone curative resection of low rectal cancer were studied. DIS was detected by HE stain. LVD was examined by immunohisto-chemical LYVE-1 (lymphatic vessel endothelial hyaluronan receptor). The association of LVD with DIS and other clinicopathological factors were examined.

RESULTSDIS (range 0.1-2.4 cm, mean 0.31 cm) was present in 44(47.8%) patients with low rectal cancer, including 23(52.3%) cases with cancer emboli in lymphatic vessels. LVD of peritumoral lesion was significantly higher than that of intratumoral lesion. LVD of DIS subgroup was significantly higher than that of non-DIS subgroup. Positive correlation was found by rank correlation test between the length of DIS and the LVD at peritumor tissue in DIS group (n=44, r=0.755, P<0.01). LVD was also positively correlated with the infiltration extent, lymphatic invasion and lymph node metastasis.

CONCLUSIONSLymphangiogenesis plays an important role in rectal cancer metastasis and cancer emboli in lymphatic vessels is the most common modality of DIS. The LVD is positively correlated with DIS, which may be helpful to determine the distal clearance length of rectal cancer.

OBJECTIVETo summarize the histological and clinical characteristics of 40 cases with Burkitt's and Burkitt-like lymphoma in children, to evaluate the effects of treatment with international regimen, and to explore the treatment-related complications and prognostic factors.

METHODSForty patients with Burkitt's and Burkitt-like lymphoma were registered in Beijing Children Hospital from Feb 2003 to Apr 2006. The diagnosis was confirmed by histology and immunohistochemistry of biopsy, and clinical staging by the examination of imaging, cerebrospinal fluid and bone marrow based on St. Jude system. Intensive, short-term chemotherapy witch was modified from LMB89 protocol was given to the patients.

RESULTSOf the 40 patients, 30 were diagnosed as Burkitt's lymphoma (BL) and 10 as Burkitt-like lymphoma (BLL). Antibody against Epstein-Barr virus (EBV-Ab) was positive in 19 cases at diagnosis, only 7 of the patients were positive for EBER. Thirty-three of the cases were male and 7 female (M:F = 4.7:1); the median age was 6 years 9 months. The most frequently seen clinical characteristics were abdominal masses and surgical abdomen. Nine cases were at stage I - II and 31 cases at stage III - IV at diagnosis; CNS was involved in 4 cases and bone marrow in 2 cases. The courses of treatment were approximately 2 - 8 months. All the patients were followed up, the median follow-up period was 22.6 months. After chemotherapy, 35 patients (88.7%) were still alive during the one-year follow-up. The 3-year event-free survival (EFS) rate was 81.8%. Major toxicity was myelosuppression and mucositis. Stage III to IV of myelosuppression occurred in the most patients with unresected tumor and CNS-involvement. Of 5 patients who died, 2 died of infection, 2 died of lymphoma progression during chemotherapy, and 1 died of relapse.

CONCLUSIONBurkitt's and Burkitt-like lymphoma are the most common NHL in children with rapid clinical process. Outcome was greatly improved by current intensive, short-term chemotherapy regimen, the 3-year EFS was 81.8% including the patients who were in advanced stage. Childhood lymphoma with short clinical history, stage IV and residual disease after 3 months of therapy are associated with poor prognosis.
