Objective The objective of this study was to explore the difference factors for PHC patients by transcatheter arterial chemoembolization of different age groups of senior people in China and support reference for individualized intervention by clinical medical workers.Methods 153 cases of PHC patients by TACE were selected by convenience sampling method from October 2013 to June 2014.The data were collected using general data questionnaire,Health Promotion Strategy Scale,QOL-LC,Memorial Symptom Assessment Scales and Social Support Scale to evaluate the physical,psychological and social aspects of the PHC patients.We divided the patients into young,middle-aged and elderly groups.Single factor and multiple factors regression analysis were used to compare the status and influencing factors.Results Psychological function,value of blood AFP,marital status entered the model and were self-care efficacy and correlated factors of young-aged patients,which could explain 50.6％ of the total varience.Physical symptoms,exploitation degree of support and intervention treatment times entered the model and were self-care efficacy and correlated factors of middle-aged patients,which could explain 47.8％ of the total varience.Symptom distress,degree of cuhural and psychological function entered the model and were self-care efficacy and correlated factors of elderly-aged patients,which could explain 42.4％ of the total varience.Conclusions The self-care efficacy were low in all ages of PHC patients by TACE,it is associated with a variety of factors.Doctors and nurses should pay more attention to the self-care efficacy for PHC patients by transcatheter arterial chemoembolization with different age groups.Also we should evaluate and make well-targeted policies and personalized inter-ventions to promote self-management self-efficacy.

OBJECTIVETo explore the therapeutic effect of acupuncture combined with medication on continuing unovulation infertility.

METHODSFifty cases of continuing unovulation infertility were randomly divided into an observation group and a control group, 25 cases in each group. The observation group was treated with Chinese herbal decoction plus acupuncture. Culuanpao decoction, Cupailuan decoction and Cuhuangti decoction were respectively given according to different menstrual cycles and acupuncture and moxibustion at Guanyuan (CV 4), Zhongji (CV 3), Luanchao (ovary), etc. The control group was treated with oral administration of Clomiphene and intramuscular injection of Chorionic Gonadotropin. They were treated for 6 cycles and the ovulation rate and the pregnancy rate were observed.

RESULTSThere was no significant difference in the ovulation rate between the two groups (P > 0.05). The pregnancy rate of 44.0% in the observation group was significantly higher than 16.0% in the control group (P < 0.05). The observation group was superior to the control group in the score of mucus and the endometrial thickness.

CONCLUSIONBoth acupuncture combined with medication and oral administration of clomiphene plus intramuscular injection of chorionic gonadotropin have higher ovulation rate, and the former was higher than the latter in the pregnancy rate.

The key challenge to generate engineered cells by synthetic biology for producing 7-dehydrocholesterol (7-DHC) in a high titer is the match between functional module and chassis. Our study focused on solving this problem by combining different promoters and yeast chassis to increase 7-DHC production. To optimize the chassis in order to accumulate zymosterol, the substrate for 7-DHC synthesis, we overexpressed truncated HMG-CoA reductase (tHmglp) and squalene epoxidase (Erglp), both are key genes of yeast endogenous zymosterol biosynthetic pathway. In addition, we knocked out C-24 methyl transferase (Erg6p) and C-22 dehydrogenase (Erg5p) to inhibit the conversion of zymosterol to ergosterol. By introducing heterologous C-24 reductase under three promoters with different strengths, namely TDH3p, PGK1p and TDH1p, we constructed functional modules of diverse activities. Nine engineeredcells were generated based on the combination of these three modules and three chassis. The result shows that the engineered cell composed of functional module regulated by TDH3p and chassis SyBE_000956 had the highest 7-DHC production, indicating a better match than others. This study provides evidences for importance of match and empirical support for rational design of subsequent researches.

Objective:Semaphorin 4D (Sema4D) acts as a regulator for axon guidance in central nervous system development. However, new evidence indicates that Sema4D has a previously unrecognized function, namely, compensatory angiogenic factor. This study aimed to investigate the effect of Sema4D on tumor growth and vascularity of colorectal carcinoma (CRC) in nude mice. Meth-ods:Sema4D was knocked down in CRC cells by infecting the cells with lentiviruses coding for Sema4D shRNA. Two groups of cells, namely, those infected with control viruses and those infected with Sema4D shRNA viruses, were subjected to migration assay to test their ability induce endothelial cell migration. The two cell groups were subcutaneously injected into nude mice. Tumor growth was documented, and the tumors harvested from the mice were subjected to immunohistochemistry or immuno fl uorescence analyses. Re-sults:In vitro migration assay results indicated that media conditioned by HCT-116 cells infected with Sema4D shRNA lentiviruses in-duced low endothelial cell migration. The two groups of subcutaneously inoculated cells showed 100%tumorigenicity. However, tumor growth rates were significantly different between the two groups. Xenografts in which Sema4D was downregulated showed marked re-duction in tumor size and vascularity. Conclusion:Cancer cells may highly express Sema4D to trigger net neo-angiogenesis and gener-ate a tumor blood supply system. Thus, Sema4D could potentially be a target in anti-angiogenic therapy of CRC patients.

AIMTo study the cutaneous permeation kinetics and pharmacodynamics of lidocaine gel.

METHODSThe concentration of lidocaine in dermis following topical application in rats was determined by the cutaneous microdialysis technique and related parameters were calculated; the pharmacodynamics of the gel was evaluated by electric stimulation method with EMLA (eutectic mixture of local anesthetics) cream as a control.

RESULTSThe peak of percutaneous absorption kinetic profile of lidocaine gel across rat skin occurred at 1.25 h; the onset time of local anesthetic action of lidociane gel was similar to that of EMLA, but both the duration and depth of anesthetic effect were superior to EMLA cream.

CONCLUSIONLidocaine gel showed good anesthetic effect. The minimum effective concentration of lidocaine in dermis is 12 mg.L-1.

The direct acting substances of Cuscuta chinensis in vivo were preliminarily identified through the correlation analysis of "metabolites-effect identification" model. The ovariectomized female rats were i.g administered with 95% ethanol extract part, 40% ethanol elution part and n-butanol extract part of Cuscuta chinensis. The serum fingerprints of different parts and times of administration were established by UPLC/Q-TOF-MS. At the same time, serum estradiol (E₂), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels were detected. Bivariate correlation analysis and grey correlation analysis were used to screen estrogenic components. The results showed that nine direct acting substances in vivo highly related to estrogen effect were found in the drug containing serum, which were hyperoside, astragalin, methyl quercetin glucuronide, quercetin-diglucuronide, quercetin, apigenin, isoquercitrin, kaempferol glucuronide and kaempferol. We can preliminarily screen out the direct acting substance of estrogen effect of Cuscuta chinensis in vivo based on the research idea of serum spectrum effect correlation. It provides a reliable basis for revealing the estrogeneffective substances of Cuscuta chinensis and confirming the quality markers. This experiment was approved by Harbin University of Commerce Ethics Committees (Approval No. HSDU2020-065).

OBJECTIVETo discuss the best surgical approach to the skull base neoplasms.

METHODSRetrospective analysis the 79 skull base neoplasms cases treated with surgical resection in Qilu hospital of Shandong university from 1992 to 2002. Eleven surgical approaches including midfacial degloving, frontal coronal discission, nasal eversion, maxillary swing, partial maxillary resection, total resection of orbit, mandibular swing, combination of front, temple, preauricular, post aureum, neck, and transoral approaches were used to resect the tumor which involved fossae pterygopalatine, paranasal sinuses, nasopharynx, antero, meso and posterobasilar region, lobi frontalis and lobi temporalis of cerebrum.

RESULTSSeventy-nine skull base neoplasms were totally removed and no one died from the operation. Although 5 cases complicated with cerebrospinal fluid leak and all recovered within 1 week, no serious cranium-cerebrum complication occurred. In 29 patients with benign tumor including 11 cases of meningioma, 3 cases of chondroma, 1 case of hemangio-meningioma, 1 case of cavernous hemangioma, 2 cases of osteodysplasia fibromas, 9 cases of neurofibroma, 1 case of glomus jugular tumor, 1 case of neurilemmoma, 19 have survived over 5 years and the longest one has survived over 8 years. For 50 patients with malignant tumor including 3 cases of well-differentiated squamous cell carcinoma, 17 cases of moderately differentiated squamous cell carcinoma, 11 cases of poorly differentiated squamous cell carcinoma, 1 case of undifferentiated carcinoma, 2 cases of chondrosarcoma, 5 cases of canceration of papilloma, 2 cases of adenocarcinoma, 1 case of esthesioneuroblastoma, 2 cases of malignant fibrohistiocytoma, 1 case of fibrosarcoma, 2 cases of malignant mixed tumour, 3 cases of sarcoma survival rates of 3 and 5 years were 59.2% (29/49), 38.5% (10/26) respectively.

CONCLUSIONIn order to resect the tumor completely and reduce the complication and malformation as far as possible, different surgical approaches must be designed according to the pathological changes characters and involved area,and the surgeon should select the shortest approach, avoid to damage the important neurovascular structure, and resect the tumor through the natural anatomy space by the shelter incision.

ObjectiveTo investigate the development trend of drinking water type of endemic fluorosis in Qinghai province, and to provide the basis for the prevention and treatment of the disease. MethodsIn 2009, six monitoring counties were chosen by using simple random sampling methods, all diseased villages of the six monitoring counties were classified into light, moderate and severe disease types according to water fluorine content on the historical data, and 1 village was respectively chosen from each type. In monitoring villages with improved water, 3 tap water and one source water samples were collected, respectively. Five water samples were collected randomly in water unimproved monitoring villages according to water well locations of east, west, south, north and center. The fluorine content in water and urine was determined according to the Standard Testing Methods for Drinking Water (GB/T 5750-2006). Children aged 8 to 12 were examined for dental fluorosis by Dean method.Clinical osteofluorosis of all the resident over the age of 16 was examined, 2 village of these counties were randomly selected, and clinically diagnosed patients with skeletal fluorosis were examined again by X-ray using Diagnostic Criteria of Endemic Skeletal Fluorosis (WS 192-2008). Urine sample of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected and urinary fluoride was determined by F-ion selective electrode method (WS/T 89-2006). ResultsImproving water projects had been implemented in 14 monitoring villages of the 18 villages in 6 counties, the rate of improved-water was 77.78％(14/18). Among the 14 projects, 5 improved-water projects ran normally, and 9 projects ran with intermittently water supply. Seventy-five water samples were tested, themean of water fluoride was 0.48 mg/L. The prevalence of dental fluorosis was 31.95％ (285/892), that of clinical skeletal fluorosis was 36.55％(1570/4295) and the X-ray detection rate of skeletal fluorosis was 25.64％ (20/78).Five hundred and seventy-one urine samples of children were determined, and geometric mean of urinary fluorine was 1.04 mg/L; 370 adult urine samples were determined, and geometric mean of urinary fluorine was 1.52 mg/L Conclusion Epidemic of drinking water type of endemic fluorosis is still serious in Qinghai province, and drinking water defluoride measures should be further strengthened and improved.

Objective To investigate the prevalence change of drinking water type of endemic fluorosis and the effect of control measures implemented in Huangyuan county of Qinghai province. Methods In 2009, all the endemic fluorosis villages in Huangyuan county were divided into two degrees, light and medium, according to the water fluorosis content before implementing the improving water project, 1 to 2 villages were selected from each degree village, respectively,as monitoring sites, and a total of 3 villages were selected. Source water and tap water samples were collected from each village and water fluoride concentration was determined. Dental fluorosis of all children aged 8 to 12 of monitoring villages was examined, and urine samples were collected by age group of children for determination of urinary fluoride. Clinical skeletal fluorosis of adults over 16 years of age was examined, and 20 copies of adults urine samples were collected to determine urinary fluoride. One village was selected in the 3 villages monitored to conduct X-rays examination of skeletal fluorosis. Water fluoride was tested in accordance with the "Non-metallic Targets Test Methods for Drinking Water" (GB/T 5750.6-2006); urinary fluoride was tested by fluoride ion-selective electrode method (WS/T 89-1996); dental fluorosis was diagnosed using Dean method;adult skeletal fluorosis was diagnosed by "Clinical Diagnostic Criteria for Endemic Skeletal Fluorosis"(WS 192-2008). Results Twelve water samples were assayed, water fluoride was (0.35 ± 0.43) mg/L. The detectable rate of dental fluorosis of 122 children aged 8-12 was 34.43%(42/122) and the geometric mean urinary fluoride was 0.89 mg/L of the 96 children. Of the 834 adults aged 16 and over, clinical detection of skeletal fluorosis was 47.72% (398/836) and geometric mean urinary fluoride was 1.10 mg/L of the 65 cases of adult urine samples assayed, detection rate of X-rays was 31.4% (11/35) in Gangou village of the 35 adults examined.Conclusions In Huangyuan county, water fluoride of the 3 surveyed villages are normal but the endemic fluorosis is still serious.
