Abstract
Liver disease is a serious public health problem worldwide, affecting human health. However, there are still many unmet needs for the treatment of liver disease, especially with new therapeutic drugs. At present, there is no treatment method to eradicate the hepatitis B virus, nor are there therapeutic drugs for liver fibrosis, liver failure, and others. Chemotherapy and targeted immunotherapy are still unsatisfactory for liver cancer. This article provides an overview of the current status and challenges that arise in new drug research and development for liver diseases.

Abstract
Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

Abstract
Objective: To evaluate the application value of metagenomic next-generation sequencing (mNGS) in the diagnosis and treatment of pulmonary infection in immunocompromised patients. Methods: A total of 78 patients with immunocompromised pulmonary infection [55 males and 23 females, aged (50.3±16.9) years] and 61 patients with non-immunocompromised pulmonary infection [42 males and 19 females, aged (63.6±15.9) years] in the Intensive Care Unit of the First Medical Center of College of the Pulmonary & Critical Care Medicine, Chinese PLA General Hospital from November 2018 to May 2022 were retrospectively selected. Patients in both groups received bronchoalveolar lavage fluid (BALF) mNGS and conventional microbiological tests (CMTs) while clinically diagnosed with pulmonary infection. The diagnostic positive rate, pathogen detection rate and clinical coincidence rate of the two methods were compared. At the same time, the difference of adjustment rate of anti-infective treatment strategy based on the results of mNGS detection was compared between the two groups. Results: The positive rates of mNGS in patients with pulmonary infection were 94.9% (74/78) and 82.0% (50/61) in the immunocompromised group and the non-immunocompromised group, respectively. The positive rates of CMTs in patients with pulmonary infection were 64.1% (50/78) and 75.4% (46/61) in the immunocompromised group and the non-immunocompromised group, respectively. The positive rates of mNGS and CMTs in patients with pulmonary infection in immunocompromised group showed a statistically significant difference (P<0.001). The detection rates of mNGS in the immunocompromised group for pneumocystis jirovecii and cytomegalovirus were 41.0% (32/78) and 37.2% (29/78), respectively, and the detection rates of Klebsiella pneumoniae, chlamydia psittaci and Legionella pneumophila were 16.4% (10/61), 9.8% (6/61) and 8.2% (5/61) in the non-immunocompromised patients, respectively, which were higher than those of CMTs [1.3% (1/78), 7.7% (6/78), 4.9% (3/61), 0 and 0] (all P<0.05). In the immunocompromised group, the clinical coincidence rates of mNGS and CMTs and were 89.7% (70/78) and 43.6% (34/78), respectively, with a statistically significant difference (P<0.001). In the non-immunocompromised group, the clinical coincidence rates of mNGS and CMTs were 83.6% (51/61) and 62.3% (38/61), with a statistically significant difference (P=0.008). In the immunocompromised group, according to the results of the etiology of mNGS, the adjustment rate of anti-infection treatment strategy was 87.2% (68/78), while in the non-immunocompromised group, the adjustment rate of anti-infective treatment strategy was 60.7% (37/61), with a statistically significant difference (P<0.001). Conclusion: In patients with immunocompromised pulmonary infection, mNGS has more advantages than CMTs in diagnostic positive rate, diagnosis rate of mixed infection, pathogen detection rate and guidance of anti-infection treatment strategy adjustment, which is worthy of clinical promotion and application.

Abstract
Objective: To investigate death and attrition in HIV-infected children under initial antiretroviral therapy (ART) and associated factors in Guangxi Zhuang autonomous region. Methods: This retrospective cohort study was conducted in HIV-infected children under initial ART in Guangxi from 2004 to 2019, data from ART information system of National comprehensive AIDS prevention and treatment information system. Cox proportional hazards models were used to assess factors associated with the death and attrition. Results: In 943 HIV-infected children, the overall mortality and attrition rates were 1.00/100 person-years and 0.77/100 person-years, respectively. The mortality and attrition rates within the first year of ART were 3.90/100 person-years and 1.67/100 person-years, respectively. The cumulative survival rate during the first, second, fifth and tenth year after ART was 96.14%, 95.80%, 93.68% and 91.54%, respectively. Multivariate Cox proportional hazards models results showed that being female (aHR=2.00, 95%CI: 1.17-3.40), CD4+T lymphocytes (CD4) counts before ART <200 cells/μl (aHR=2.79, 95%CI: 1.54-5.06), weight-for-age Z score before ART <-2 (aHR=2.38, 95%CI: 1.32-4.26), hemoglobin before ART <80 g/L (aHR=2.47, 95%CI: 1.24-4.92), initial ART with LPV/r (aHR=5.05, 95%CI: 1.15-22.12) were significantly associated with death; being female (aHR=2.23, 95%CI: 1.22-4.07) and initial ART with LPV/r (aHR=2.02, 95%CI: 1.07-3.79) were significantly associated with attrition. Conclusions: The effect of ART in HIV-infected children in Guangxi was better, but the mortality and attrition rates were high within the first year of treatment. It is necessary to strengthen the training in medical staff and health education in HIV-infected children and their parents in order to improve the treatment effect.

Abstract
Objective: To analyze the early outcome of one-stage hybrid technique in the treatment of Stanford type-A aortic dissection involving the arch and compare its therapeutic efficacy with the classical frozen elephant trunk technique (FET). Methods: A total of 106 patients with Stanford type-A aortic dissection involving the arch in Department of Cardiac and Vascular Surgery, 1st Affiliated Hospital of Soochow University from October 2015 to October 2019 was collected. All patients in this group were treated with one-stage hybrid technique (modified arch debranching technique) without deep hypothermia circulation. Meanwhile, 30 patients with Stanford type A dissection involving the arch who underwent FET from January 2014 to September 2015 were collected. The therapeutic effects of the two surgical methods were analyzed and compared. Results: The age [M (Q1, Q3)] of 106 patients in hybrid group was 49.0 (40.0, 55.0) years, including 89 males and 17 females. The age [M(Q1, Q3)] of 30 patients in FET group was 49.5 (41.5, 65.3) years, including 24 males and 6 females. The time [M(Q1, Q3)] of using ventilator in hybrid group was 56.0 (38.0, 72.0) h, which was shorter than 127.0 (92.0, 145.0) h in FET group (P<0.001). The incidence of cerebral infarction in hybrid group was 2.8% (3 cases), which was lower than 13.3% (4 cases) in FET group (P=0.042); the incidence of postoperative renal insufficiency in hybrid group was 7.5% (8 cases), which was lower than 23.3% (7 cases) in FET group (P=0.023); the ICU time [M (Q1, Q3)] in hybrid group was 8.0 (6.0, 10.0) d, which was shorter than 14.0 (8.3, 24.0) d in FET group (P<0.001). Conclusion: Compared with FET, one-stage hybrid technology is safer and more effective in the treatment of Stanford type A aortic dissection involving the arch. Its short-term therapeutic efficacy appears good.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Scrophularia ningpoensis Hemsl. (known as Xuanshen) has been used in China for centuries as a traditional medicinal plant to treat numerous diseases including inflammation, hypertension, cancer, and diabetes. AIM OF REVIEW In this review, we provide an update on the botany, pharmacology, phytochemistry, pharmacokinetics, traditional uses, and safety of S. ningpoensis to highlight future research needs and potential uses of this plant. MATERIALS AND METHODS All information on S. ningpoensis was obtained from scientific databases including ScienceDirect, Springer, PubMed, Sci Finder, China Knowledge Resource Integrated Database from the China National Knowledge Infrastructure (CNKI), Google Scholar, and Baidu Scholar. Additional information was collected from Chinese herbal medicine books, Ph.D. dissertations, and M.Sc. Theses. Plant taxonomy was verified by "The Plant List" database (http://www.theplantlist.org). RESULTS S. ningpoensis displays fever reducing, detoxifying, and nourishing 'Yin' effects in traditional Chinese medicine (TCM). More than 162 compounds have been identified and isolated from S. ningpoensis, including iridoids and iridoid glycosides, phenylpropanoid glycosides, organic acids, volatile oils, terpenoids, saccharides, flavonoids, sterols, and saponins. These compounds possess a diverse variety of pharmacological properties that affect the cardiovascular, hepatic, and nervous systems, and protect the body against inflammation, oxidation, and carcinogenesis. CONCLUSIONS Modern pharmacological studies have confirmed that S. ningpoensis is a valuable Chinese medicinal herb with many pharmacological uses in the treatment of cardiovascular, diabetic, and liver diseases. Most of the S. ningpoensis activity may be attributed to iridoid glycosides and phenylpropanoid glycosides; however, detailed information on the molecular mechanisms, metabolic activity, toxicology, and structure-function relationships of active components is limited. Further comprehensive research to evaluate the medicinal properties of S. ningpoensis is needed.

Abstract
This study aimed at probing into the function of muscone in ameliorating myocardial ischemiareperfusion (I/R) injury and exploring the underlying mechanism. To analyze the function of muscone, H9c2 cardiomyocytes were treated with hypoxia/reoxygenation (H/R) and Sprague-Dawley (SD) rats were treated with left anterior descending (LAD) of the coronary artery ligation for 30 min and reperfusion for 2 h to induce myocardial I/R injury. Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot were used to detect the expression of SIRT3. MTT assay and TUNEL assay were performed to investigate H9c2 viability and apoptosis, respectively. ELISA was employed to determine the expressions of inflammatory cytokines TNF-α, IL-6 and IL-1β, and myocardial injury markers CK and LDH. Oxidative stress markers MDA and SOD, and ROS expression levels were also detected. SIRT3 inhibitor 3-TYP was used to further confirm whether muscone worked via the augmentation of SIRT3. Herein, we found that muscone significantly inhibited inflammation and oxidative stress in H9c2 cardiomyocytes in a dose-dependent manner. H9c2 viability was promoted by muscone while apoptosis was inhibited. In SD rats, pre-treatment of muscone alleviated I/R injury-induced cardiac function dysregulation and left ventricle remolding. Furthermore, muscone increased SIRT3 expression at both mRNA and protein levels. With 3-TYP inhibiting SIRT3, the protective effects of muscone in H9c2 cardiomyocytes and SD rats were all significantly alleviated. In summary, muscone can attenuate inflammation, oxidative stress and cardiomyocytes injury in H9c2 cells treated with H/R and alleviate myocardial I/R injury of SD rats, which are dependent on SIRT3.

Abstract
Objective: Although single port laparoscopic surgery has achieved good clinical results, many surgeons are discouraged by the difficulties of operation, conflict of instruments, lack of antagonistic traction, and straight-line perspective. Therefore, some surgeons have proposed a single incision plus one hole laparoscopic surgery (SILS+1) surgical method. This study explored the safety and feasibility of SILS+1 for radical resection of colorectal cancer. Methods: A descriptive cohort study was carried out. The clinical data, including the operation, pathology and recovery situation, of 178 patients with colorectal cancer undergoing SILS+1 at Department of General Surgery, Nanfang Hospital, Southern Medical University from March 2018 to January 2019 were prospectively collected and retrospectively analyzed. Clavien-Dindo criteria was used for postoperative complication evaluation and visual analog scale was used for pain standard. Follow-up studies were conducted through outpatient service or telephone and the follow-up period was up to May 2019. Results: A total of 178 patients with colorectal cancer underwent SILS+1, including 111 male patients (62.4%) with an average age of 59 years. Eleven (6.2%) patients received added 1-3 operation ports during operation, and 1 patient was converted to open surgery due to ileocolic artery hemorrhage. The operative time was (135.2±42.3) minutes. The intraoperative blood loss was (34.6±35.5) ml. The number of harvested lymph nodes was 33.1±17.6. The distal margin was (4.7±17.8) cm. The proximal margin was (10.2±5.3) cm. Operation-related complications were observed in 16 patients (9.0%) within 30 days after the operation, of whom 6 had Clavien-Dindo III complications (3.4%). The postoperative pain scores were lower than 3. The average postoperative hospital stay was (5.6±2.6) days. Three patients (1.7%) returned to hospital within 30 days after operation due to intestinal obstruction and infection around stoma. The cosmetic evaluation of all the patients was basically satisfied. Conclusion: SILS+1 is safe and feasible in the treatment of colorectal cancer, and can reduce the postoperative pain.

Abstract
Objective: To analyze the effects of HIV non-occupational post-exposure prophylaxis (nPEP) in men who have sex with men (MSM) in Nanning and Liuzhou, Guangxi Zhuang Autonomous Region. Methods: Participants were recruited through community publicity and advocacy under a "Trinity" approach among non-governmental organizations (NGO), CDCs/hospitals and pharmacies. Basic information, drug taking and follow-up tests of participants who had enrolled for 28 days of the research were collected. Descriptive statistics were used for data analysis. Results: From September 2017 to March 2019, a total of 213 MSM cases consulted for nPEP service, 159 of them were eligible for nPEP, and 154 were enrolled in the study for drug taking. For 132 cases enrolled in the study for 28 days and above, 118 completed the 28-day course of antiretroviral therapy (ART), while 10 failed to complete the 28-day course of ART, and 4 could not be confirmed whether completed the full course of ART due to loss of contact. For those who completed 28-day course of ART, 94.1% (111/118) and 75.4% (89/118) respectively received HIV tests at 4-6 weeks and 3 months after exposure, the results were all HIV negative. Conclusion: Under the "Trinity" approach, taking antiviral drugs earlier after HIV non-occupational exposure can effectively reduce the risk of HIV infection and to some extent, reduce the new infection cases.

Abstract
Objective: To understand the characteristics and associated factors of newly reported HIV/AIDS cases with non-marital or non-commercial heterosexual transmission, in Guangxi Zhuang Autonomous Region (Guangxi), 2015-2018. Methods: Information of newly reported HIV/AIDS cases aged ≥18 years in Guangxi between 2015 and 2018 was collected from the National Comprehensive HIV/AIDS Information System. Unconditional logistic regression model was used to access those factors that were associated with HIV infections through non-marital or non-commercial heterosexual contact. Results: Between 2015 and 2018, a total number of 35 497 HIV/AIDS cases, aged ≥18 years were newly reported in Guangxi. Among them, 32 648 (92.0%) were infected heterosexually while 10 500 were infected through non-marital or non-commercial heterosexual behavior. Non-marital or non-commercial heterosexual transmission accounted for 29.6% (10 500/35 497) of the newly reported HIV/AIDS cases, and 32.2% (10 500/32 648) of those with heterosexual transmission. Males counted for 53.5% (5 617/10 500) of non-marital or non-commercial heterosexual transmission and males to females ratio was 1.2∶1 (5 617∶4 883). Those married or had regular sexual partners counted for 55.9% (5 873/10 500). Commercial heterosexual transmission appeared the main mode of HIV transmission for males (64.4%,16 516/25 633) while main mode for females was non-marital or non-commercial heterosexual transmission and counted for 49.5% (4 883/9 864). Results from the multivariate logistic regression analysis showed that adjusted OR of female HIV/AIDS infected HIV via non-marital or non-commercial heterosexual transmission, was 3.98 times (95%CI: 3.78-4.20) hight than that of males. Among the group aged<50 years and the aged 50-59 years, the adjusted ORs were 1.35 times (95%CI: 1.27-1.44) and 1.13 times (95%CI: 1.05-1.21) hight than that of aged ≥60 years. Those who were single/divorced/widowed, the adjusted OR was 1.53 times (95%CI: 1.45-1.61) hight than that of those married/regular partners. Those with junior high school education, high school education and above the adjusted ORs were 1.22 times (95%CI: 1.16-1.29) and 1.18 times (95%CI: 1.10-1.27), compared to those only with education levels of primary school or below. Conclusions: The number of HIV/AIDS cases via non-marital or non-commercial heterosexual transmission accounted for nearly 30.0% of all the routes of HIV transmission in Guangxi, 2015-2018. Female, aged<60 years old, single/divorced/widowed and having had junior and above high school education etc., appeared as risk factors on non-marital or non-commercial heterosexual transmission, among newly reported HIV/AIDS in Guangxi.

Abstract
Objective: To explore influence on physical development of children aged 18 months from HIV-positive mothers for prevention mother to child transmission of HIV (PMTCT) in Guangxi Zhuang autonomous region, and provide evidence for the improvement PMTCT program. Methods: This retrospective case control study was conducted in 554 HIV negative infants aged 18 months whose HIV positive mothers had received PMTCT services reported through PMTCT system database from January 1, 2010 to December 31, 2017 and 1 109 healthy infants born in 2017, whose mothers were healthy, in Lingshan, Luzhai, and Hengxian counties, ranking top three counties with high HIV infection prevalence, in Guangxi. PMTCT data and physical development data such as height, weight and head circumference of children aged 18 months were collected. The physical dysplasia in the infants was defined as at least one of the three main indicators of height, weight and head circumference below the normal range. Results: The number of HIV-positive mother and their infants in the case group were 667 and 554 respectively, and the PMTCT rates were 91.15% (608/667) and 96.57% (535/554) respectively. HIV positive rate, mortality rate and mother to child transmission rate of the infants aged 18 months were 1.44% (8/554), 3.07% (17/554) and 1.91% (8/418) respectively, and the physical examination results of the infants aged 18 months showed that the physical dysplasia rate was 30.51% (169/554). Among the 1 109 infants in the control group, the physical dysplasia rate was 9.83% (109/1 109). The difference between the case group and the control group was significant (P<0.01). Conclusion: The PMTCT rates of HIV positive mother and their children were more than 90.00%, respectively. However, poor physical development rate of infants aged 18 months were more than 30.00%. The possible influence of PMTCT on physical development of the infants aged 18 months of HIV positive mother's needs to be further studied.

Abstract
Objective: To examine the overall status of the Jiangsu Province Coronary Artery Bypass Grafting Registry database. Methods: The patients date of Jiangsu Province Coronary Artery Bypass Grafting Registry database from October 2017 to December 2019 was collected retrospectively.Risk factors, history, cardiac function (New York Heart Association class), extent of coronary artery lesion, European system for cardiac operative risk evaluation Ⅱ (EuroSCORE Ⅱ), cardiopulmonary bypss, arterial grafts, the numbers and flow of grafts and postoperative major adverse cardiac and cerebrovascular event(MACCE) information were analyzed. The clinical data of patients underwent on-pump CABG(ONCABG) or off-pump CABG (OPCAB) were compared by t test or χ(2) test. Results: Up till December 2019, the database enrolled 7 138 patients, in which 4 661 patients receiving primary isolated CABG. There were 3 486 males and 1 175 females with the age of (64.6±8.1) years (range:31 to 87 years). There were coronary left main disease in 960 patients, triple vessel disease in 3 934 patients, both left main and triple vessel disease in 837 patients, ejection fraction>50% in 3 841 patients, cardiac function class Ⅲ to Ⅳ in 1 664 patients. EuroSCORE Ⅱ was (2.3±0.7)% (range: 0.5% to 35.8%). There were 2 731 patients (58.59%) underwent ONCABG and 1 930 patients (41.41%) underwent OPCAB. There were 4 144 patients (88.91%) for whom the left internal thoracic artery was harvested. Seven centers (2 centers routinely) used left radial artery, 5 centers (3 centers routinely) used the transit time flow meter. The graft was 3.4±0.7 (range:1 to 7), the aortic crossclamp time was (65.0±20.4) minutes (range: 21 to 196 minutes), the cardiopulmonary bypass time was (90.0±24.2) minutes (range: 33 to 227 minutes). In-hospital death ocurred in 84 patients(1.80%), while re-operation in 93 patients (2.00%), myocardial infarction in 71 patients (1.52%), cerebral infarction in 33 patients (0.71%) and dialysis in 56 patients (1.20%). There were 2 936 patients prescribed with secondary prevention drugs(62.99%).Comparing with OPCAB group, ONCABG group had younger age, more female, more diabetes mellitus, more history of myocardial infarction and percutaneous transluminal coronary angioplasty, poorer cardiac function and coronary lesions, higher EuroSCORE Ⅱ, preoperatively (all P<0.05), and was associated with higher MACCE (135/2 731 vs. 71/1 930, χ(2)=4.280, P=0.039), and of more grafts, transfusion and intra-aortic balloon counterpulsation application (all P<0.05). Conclusions: Jiangsu Province Coronary Artery Bypass Grafting Registry database is generally in good operation, and some parameters still need to be improved. Comparing with OPCAB group, ONCABG has more severe preoperative general conditions, while the outcomes is acceptable.

Abstract
Objective:To explore effect of mobile platform in improving compliance and efficacy of subcutaneous immunotherapy(SCIT) in children with allergic rhinitis(AR). Method:From January to June 2018, 86 children diagnosed with AR and receiving SCIT were selected as research objects. According to the random sequence generated by the computer, the research objects were randomly assigned to the experimental group and the control group, with 43 cases in each group. The control group received conventional SCIT management, while the experimental group received mobile platform SCIT management relying on smart phones and computers. The SCIT shedding rate at the initial stage and the time taken to reach the maintenance period were compared between the two groups, as well as the visual simulation scale of rhinitis symptoms, four-point score and rhinoconjunctivia-related quality of life scores before and at the 6th month after the intervention. Result:There was no statistically significant difference in the initial SCIT shedding rate between the two groups(P>0.05), and the average duration of the maintenance period of the experimental group was shorter than that of the control group, with statistically significant difference(P<0.05). At the 6th month after intervention, there was no statistically significant difference in the scores of rhinitis symptoms by the four-point method between the two groups(P>0.05), and there were statistically significant differences in the visual simulation scale of rhinitis symptoms and the scores of children's rhinoconjunctivia-related quality of life(P<0.05). Conclusion:This study confirmed that the application of a mobile platform is of great significance for improving compliance and the treatment effects of SCIT in children with AR.

Abstract
The endophytic fungi from root,main stem,branch and leaf of Scrophularia ningpoensis were isolated from Zhejiang,whether these strains could yield harpagide or harpagoside were tested by HPLC and LC-MS. According to the morphological characteristic and the similarity of the nucleotide sequence of internal transcribed spacer( ITS) between r DNAs,the strains producing harpagide or harpagoside were identified. The results showed that 210 strains were isolated from the samples,which were classified into 9 orders,13 families and 17 genera by morphological study. Harpagide was detected in endogenous fungi ZJ17 and harpagoside was detected in endogenous fungi ZJ25 by HPLC coupled with LC-MS. ZJ17 was identified as Alternaria alternate and ZJ25 was identified as A.gaisen by its morphology and authenticated by ITS( ITS4 and ITS5 regions and the intervening 5. 8 S rDNA region).

Abstract
Objective: To analyze the change trend of HIV genetic subtypes and compare the first CD(4)(+)T cell counts of newly diagnosed HIV infected patients in Liuzhou from 1998 to 2012, and provide a reference for AIDS prevention and control. Methods: Newly diagnosed HIV-infected patients from 1998 to 2012 in Liuzhou were selected through national HIV/ADIS comprehensive response information management system. Their plasma samples were used for RNA gene extraction, amplification, sequencing and genotyping. Coharan-Armitage trend test was used to analyze the ratio trend of genetic subtypes and phylogenetic clusters of HIV and Wilcoxon Rank Sum Test was used to compare the first CD(4)(+)T cell counts (CD(4)) of the different subtype HIV infected patients. Results: A total of 1 877 newly diagnosed HIV infected patients were included in the study. From 1998 to 2012, the proportions of CRF01_AE and CRF01_AE (Cluster 1) increased from 78.4% (76/97) to 91.5% (1 441/1 574), from 63.9% (62/97) to 74.0% (1 164/1 574), and the proportion of CRF07_BC decreased from 17.5% (17/97) to 4.6% (72/1 574), respectively (Z=4.632, P<0.001; Z=2.455, P=0.014; Z=-5.943, P<0.001). The median and interquartile range of the first CD(4) of the patients infected with subtype CRF01_AE (Cluster 1), CRF01_AE (Cluster 2), CRF07_BC and CRF08_BC were 230 (83-375), 215 (48-351), 365 (254-503) and 334 (206-479) cell/μl, respectively. The first CD(4) levels of the patients infected with subtype CRF01_AE (Cluster 1) or CRF01_AE (Cluster 2) were significantly lower than those of CRF07_BC (Z=-4.795, P<0.001; Z=-4.238, P<0.001). Conclusion: The genetic subtypes of HIV were mainly CRF01_AE in newly diagnosed HIV-infected patients and this subtype proportion was in increase and the first CD(4) levels of the patients were low in Liuzhou during 1998 to 2012.

Abstract
Objective: To investigate the relationship between psoas muscle index (PMI) and early postoperative survival rate and the incidence of complications after liver transplantation in adults. Methods: The clinical data of 225 patients (male, n=184; female, n=41) underwent liver transplantation at the Organ Transplantation Department of First Central Clinic Institute of Tianjin Medical University from January 2014 to December 2016 were analyzed, retrospectively.Original disease: hepatitis B liver cirrhosis(44 cases), hepatitis C cirrhosis(10 cases), autoimmune liver cirrhosis(29 cases), other benign liver diseases(24 cases), liver cirrhosis with liver cancer(116 cases), hilar cholangiocarcinoma(1 case) and hepatic vascular sarcoma(1 case). The area of bilateral psoas muscle on the lower edge level of the third lumbar vertebral body was measured through preoperative CT image.The PMI was calculated using this formula: bilateral psoas muscle area (mm(2))/the square of the body height (m(2)). According to the receiver operating characteristic curve and cut-off values, the male and female patients were divided into low PMI group and high PMI group respectively.The χ(2) test, Fisher exact test and t-test was used to compare the differences in perioperative data, survival rate and postoperative complications between the two groups, respectively. Results: There were 44 patients in the low PMI group, and 181 patients in the high PMI group. ICU time was longer (82.5(62.0-128.0) hours vs.69.1(56.0-104.0) hours; P=0.006) and preoperative blood urea nitrogen level (5.86(4.35-15.52) mmol/L vs. 4.94(4.05-7.06) mmol/L; P=0.012) was higher in the low PMI group than those in the high PMI group. Incidence rates of grade 5 complication (18.2%) and grade 4a complication (18.2%) were higher in the low PMI group, and 120-day cumulative survival rate was lower than that in high PMI group(81.8% vs. 95.6%, P=0.001). On the other hand, there were no significant differences in preoperative white blood cell count level, serum creatinine level, operative time, anhepatic period time, intraoperative blood loss, and incidence of postoperative grade 3 complications between the two groups(all P>0.05). Conclusions: There is a significant correlation between PMI and early postoperative survival rate and incidence of complications.Patients with lower PMI has poor prognosis after liver transplantation.

Abstract
Objective: To understand the characteristics of HIV infected persons without long term disease progress [also known as long term non-progressors (LTNPs)], and related factors in Guangxi Zhuang Autonomous Region (Guangxi). Methods: Data of persons living with HIV and receiving no antiretroviral therapy in Guangxi by the end of 2016 were collected from the national HIV/AIDS comprehensive control and prevention information system of China. Results: By the end of 2016, there were 313 LTNPs in Guangxi, accounting for 2.3% of those being reported for more than 10 years, 5.4% of those being reported for more than 10 years and surviving, and 26.6% of those being reported for more than 10 years, surviving and receiving no antiretroviral therapy. Among the LTNPs, 87.2%(273) were men, 94.9% (297) were aged ≤ 40 years, 32.3% (101) were farmers, 55.6% (174) were single, divorced or widowed, 69.3% (217) were of Han ethnic group, 68.1% (213) were injecting drug users, and 52.1% (163) were from custody facilities. Multiple logistic regression analysis indicated that factors associated with delayed disease progression included age ≤40 years (compared with age >40 years, aOR=1.55, 95%CI: 1.31-3.12) and injection drug use (compared with sexual transmission, aOR=1.23, 95%CI: 1.10-1.74). Conclusions: A number of LTNPs existed in HIV-infected individuals in Guangxi. Further research are needed to identify the related factors, and it is necessary to conduct large sample size studies on host immunology, genetics and the virology of HIV to explore the related mechanism.

Abstract
BACKGROUND Acne vulgaris is a common chronic skin disease. Inflammation is an important pathogenetic mechanism of acne, and NLRP3 polymorphisms have been reported to be involved in the mediation and occurrence of the inflammation. However, only a few studies on NLRP3 and acne have been reported, and the mechanism remains unclear. AIM To investigate two SNPs in the NLRP3 gene in patients with acne vulgaris (AV) and healthy controls (HCs) in a Chinese population. METHODS A case-control study was performed with 428 patients with AV and 384 (HCs). The SNPs rs10754558 and rs4612666 of the NLRP3 gene were genotyped using PCR with sequence-specific primers. A dual luciferase reporter assay was performed to determine whether the SNP rs10754558 might be responsible for the altered NLRP3 gene expression in AV by disrupting the interaction between micro-RNA (miR)-4273 and NLRP3 mRNA. Additionally, the mRNA level of NLRP3 was measured by PCR in the two groups. RESULTS The frequencies of the G allele of rs10754558 were 0.54 in patients and 0.49 in HCs (P < 0.05). No significant difference was observed for SNP rs4612666. Dual luciferase reporter assay revealed that luciferase activity was downregulated by about 40% when the G allele of rs10754558 coexisted with miRNA-4273, indicating that the G allele might interfere with miR-4273 function and alter NLRP3 expression. The level of NLRP3 mRNA in patients with AV was significantly higher than that in HCs. CONCLUSIONS Our study suggests that the NLRP3 SNP rs10754558 is associated with the incidence of AV. The G allele might be a genetic risk factor for AV in the Chinese population.

Abstract
Objective: To understand the dynamic variation of BMI and influencing factors among HIV/AIDS patients receiving highly active anti-retroviral therapy (HAART) in Liuzhou, Guangxi Zhuang Autonomous Region (Guangxi). Methods: HIV/AIDS patients receiving HAART for the first time since 1 January 2013 were selected. Data on BMI was analyzed among patients receiving HAART at baseline,6 months and 12 months after treatment. By using the general linear model repeated measures of analysis of variance, BMI dynamic variations and influencing factors were described and analyzed. Results: The average BMI of 2 871 patients at baseline, 6th months and 12th months appeared as (20.65±3.32), (20.87±3.22) and (21.18±3.20), respectively, with differences all statistically significant (F=18.86, P<0.001). BMI were increasing over time with treatments (F=37.25, P<0.001). Main influencing factors were noticed as: age, sex, marital status, baseline data of CD(4)(+)T cells and the WHO classification on clinical stages. Conclusions: Higher proportion of BMI malnutrition counts was seen among patients before receiving HAART in Liuzhou. BMI of the patients that were on HAART seemed being influenced by many factors. It is necessary to select appropriate treatment protocols on different patients so as to improve the nutritional status of the patients.

Abstract
Objective: To explore the significance of multi-parameter semiquantitative Alberta Stroke Program Early CT Score (ASPECTS) in detecting core infarction in acute ischemic stroke (AIS) patients. Methods: Twenty-one consecutive AIS patients from Beijing Hospital were retrospectively reviewed in this study from August 2016 to August 2017. All the patients presented within 6 hours since symptom onset.All the patients underwent one-stop dynamic whole brain 4D CTA-CTP scan before treatments (intravenous thrombolysis, mechanical thrombectomy, or other endovascular recanalization). MRI scan was performed in all patients 3 to 7 days after initial administration. Multi-parameter ASPECTS was calculated on the affected hemisphere regarding noncontrast CT (NCCT) map, cerebral blood flow (CBF) map, cerebral blood volume (CBV) map, mean transit time (MTT) map and MRI-DWI map by subtracting 1 point from 10 for any abnormalities visually detected. The evaluative consistency and diagnostic efficiency were analyzed by Pearson's χ(2) test, kappa identity test, and Kendall's coefficient of concordance using IBM SPSS statistics 22.0 software. Results: Compared with DWI-ASPECTS or follow-up NCCT-ASPECTS, CBV-ASPECTS had the best performance on both the kappa identity test (kappa coefficient κ=0.74)and Kendall's coefficient of concordance (τ=0.70). All the values of sensitivity (77.8%), specificity (95.5%), positive likelihood ratio (17.27) and AUC(0.87)were the highest in CBV-ASPECTS, followed by dMTT-ASPECTS. Meanwhile, the misdiagnosis rate (4.5%), missed diagnosis rate (22.2%) and negative likelihood ratio were the lowest in CBV-ASPECTS, followed by dMTT-ASPECTS. dMTT-ASPECTS had the same specificity(95.5%) as CBV-ASPECTS did and it could reveal the infarction in the areas where CBV map showed normal. NCCT-ASPECTS had the lowest sensitivity (64.7%) and highest missed diagnosis rate (35.3%). The misdiagnosis rate of CBF-ASPECTS was the highest (25.2%) and AUC was the lowest (0.76). Conclusions: Multi-parameter semiquantitative ASPECTS may predict the infarction accurately in AIS patients. Compared with the single parameter of NCCT-ASPECTS, this new method may have better detectability and diagnostic performance.

Abstract
Objective: To understand HIV-1 subtype characteristics and transmission clusters in elderly male clients and female sex workers (FSWs) of low-cost commercial sex venues in Guangxi Zhuang Autonomous Region, China. Methods: A cross sectional survey was conducted in FSWs and elderly male clients (≥50 years) of low-cost commercial sex venues in 4 cities and 9 counties in Guangxi Zhuang Autonomous Region by convenient sampling in 2012. The blood sample was collected from each case for HIV-1 antibody detection. The pol gene fragments were amplified and sequenced from viral RNA template extracted from plasma samples. The phylogenetic tree was constructed and the subtypes were identified. Results: A total of 4 048 elderly male clients and 784 FSWs were surveyed, and 116 HIV-1 infections were detected, the positive rate was 2.5% (103/4 048) in the clients and 1.7% (13/784) in FSWs. The gene amplification and sequencing of HIV-1 detected in 84 blood samples indicated that 53 pol gene sequences were successfully determined (48 blood samples from elderly male clients and 5 blood samples from FSWs). Among 53 pol sequences, 48(90.6% ), 4(7.5% ), and 1(1.9% ) sequences were identified as CRF01_AE, CRF08_BC, and CRF07_BC, respectively. Two transmission clusters were identified among CRF01_AE, including 4 sub-clusters. One transmission cluster was identified among CRF08_BC. The transmission cluster or sub-cluster were from the infected individuals at same low-cost commercial sex venue, or different low-cost commercial sex venues in the same town, or same place, or adjacent villages and towns. Conclusions: CRF01_AE was the predominant HIV-1 subtype among elderly male clients and FSWs of low-cost commercial sex venues in Guangxi Zhuang Autonomous Region, circulating in same venue or adjacent villages and towns. The HIV-1 positive male clients and FSWs might play an important role in the spread of the strains.

Abstract
Objective: To understand the HIV transmission and associated factors in newly reported HIV infected couples before diagnosis. Methods: The information about newly reported HIV infected couples in Yunnan, Guangxi, Sichuan, Henan and Xinjiang provinces (autonomous region) were collected from National HIV/AIDS Information System from 2011 to 2014. The infection order of the sero-concordant couples were determined. Logistic regression model was used to analyze the HIV transmission between couples and identify the associated factors. Cochran-Armitage trend analysis was conducted to understand the annual sero-concordant couple proportion. Results: A total of 48 931 HIV cases in couples were included in this study, among whom 12 051(24.6%) were sero-concordant couples, indicating HIV transmissions occurred between them. Multivariate logistic regression analysis showed that those who were females (OR=1.98, 95%CI: 1.89-2.08), aged >45 years (45-59 yrs: OR=1.32, 95% CI: 1.23-1.42; >60 yrs: OR=1.72, 95% CI: 1.58-1.86), had educational level of middle school education or below (illiteracy and primary school: OR=1.33, 95%CI: 1.23-1.44; middle school: OR=1.19, 95% CI: 1.10-1.28), were farmers or migrate workers (OR=1.23, 95% CI: 1.17-1.30), were infected through injecting drug use or heterosexual intercourse (injecting drug use: OR=1.33, 95% CI: 1.03-1.72; heterosexual intercourse: OR=3.65, 95% CI: 2.89-4.61), had CD4+T cells of <500 cells/μl (<200 cells/μl: OR=5.05, 95%CI: 4.62-5.52; 200-349 cells/μl: OR=3.58, 95%CI: 3.26-3.93; 350-500 cells/μl: OR=2.14, 95%CI: 1.94-2.36), reported unprotected sexual behaviors (OR=1.56, 95% CI: 1.49-1.64), were more likely to infect their couples before diagnosis. The HIV transmission proportion between couples before diagnosis decreased significantly from 28.9% (2 631/9 102) in 2011 to 25.5% (3 009/11 787) in 2014 among those infected through heterosexual intercourse. Conclusion: The proportion of HIV transmission between couples before diagnosis varied among different populations. Behavior intervention and early HIV test promoting are needed to prevent HIV transmission between couples before diagnosis in populations at high risk for HIV infection. HIV infection cases should be included in the HIV care system after diagnosis as early as possible.

Abstract
OBJECTIVE To analyse and explore the indications and efficacy of liver transplantation for benign liver tumor. METHODS From Jan.2001 to Dec.2014, 6 patients, incluing 3 males and 3 females, with benign liver tumor underwent liver transplantation in our department.There were 2 cases of hepatic epithelioid hemangioendothelioma, 1 case of hepatic cavernous hemangioma, 1 case of liver mesenchymal hamartoma, 1 case of hilar bile duct mucinous cystadenoma, and 1 case of hepatic adenoma. The data of surgical procedure, perioperative complications, postoperative management, and the outcome of follow-up were analyzed. RESULTS Six orthotopic liver transplantation from one living donor and five cadaveric donors were performed. One patient died in the perioperative period, and other patients were discharged with normal liver and kidney function. Within the follow-up time of 22 to 88 months, these patients could live the normal lives with stable graft function and nutritional status. CONCLUSIONS Liver transplantation is the most efficient treatment for unresectable and symptomatic benign lesions, with the favourable outcome.

Abstract
BACKGROUND Human leukocyte antigen (HLA) antibodies estimated by Luminex single-antigen beads, especially those that fix complement, are associated with antibody-mediated rejection and graft failure. However, the relationship between HLA antibody strength and complement-binding ability is controversial. METHODS Serum samples of 31 sensitized renal patients waiting for renal transplantation were retrospectively analyzed by IgG-Luminex to identify HLA antibodies and in parallel by C1q-Luminex to determine the complement binding of HLA antibodies. RESULTS The percentage of HLA class I antibodies binding with C1q was lower than that of HLA class II antibodies (43.2% vs. 51.3%, P = .006). The mean fluorescence intensities (MFI) of IgG-Luminex correlated with the MFI of C1q-Luminex for the same antibodies (Spearman correlation; class I, r = 0.665, P < .01; class II, r = 0.761, P < .01). Receiver operating characteristic (ROC) curve analysis showed that the MFIs of HLA antibodies by IgG-Luminex predicted their C1q-binding abilities (area under the curve [AUC] class I = 0.917; AUC class II = 0.927). Using MFI cutoff values of 8238 and 6754 in IgG-Luminex for HLA class I and class II antibodies, respectively, the sensitivity and specificity for C1q binding were 82.4% and 87.4% for class I antibodies and 90.9% and 82% for class II antibodies. CONCLUSIONS The MFI of HLA antibodies by IgG-Luminex predicts the complement-binding capability to a certain extent before transplantation.

Abstract
OBJECTIVE To evaluate the feasibility and outcome of liver transplantation in the treatment of liver metastatic cancer. METHODS Four patients with pathologically confirmed liver metastatic cancer underwent liver transplantation, including one of liver metastases from pancreatic endocrine tumor, one from rectal endocrine tumor, one from stomach stromal tumor and one from colorectal carcinoma. Classic surgical method was adopted, i. e. orthotopic liver transplantation for the recipients and transplants came from cadaveric donors. RESULTS All the four patients had a smooth operation, an uneventful early postoperative recovery and good living quality. The patient with liver metastases from pancreatic endocrine tumor had liver tumor recurrence at four and a half years after the transplantation, and then underwent left lateral hepatic lobectomy, without any recurrence until now. The patient with liver metastases from rectal endocrine tumor had right renal and pelvic tumor metastasis at 16 months after the operation, and died of tumor recurrence 5 years after the liver transplantation. The patient with liver metastases from gastric stromal tumor had extensive pelvic metastases at five and a half months after the transplantation, and survived with tumor for 4 years and 6 months after the operation. The patient with liver metastases from colorectal carcinoma had extensive bilateral lung metastases at 3 months after the transplantation and died one and a half years after the operation. CONCLUSION For well-differentiated unresectable metastatic liver cancers, liver transplantation may serve as a treatment option and better treatment results can be achieved for some highly selected patients.

Abstract
To determine the risk factors associated with adverse aortic remodeling after thoracic endovascular aortic repair (TEVAR) in patients with Stanford type B aortic dissection, we performed a retrospective analysis of 54 patients between January 2009 and June 2012 at the First Affiliated Hospital of Soochow University. All patients underwent TEVAR of the descending thoracic aorta. Multiple-logistic regression analyses were performed to identify risk factors associated with aortic remodeling. True-lumen and false-lumen volumes were increased (P < 0.001) and decreased (P < 0.001) after surgery, respectively. Therefore, the remodeling index increased after surgery (1.04 ± 0.6 to 2.06 ± 1.12, P < 0.001). Remodeling index and true-lumen volume were higher in the favorable aortic remodeling group compared to the adverse aortic remodeling group (P < 0.001), while the false-lumen volume was lower in the favorable aortic remodeling group (P < 0.001). Multivariate analyses revealed a branch originating from the false lumen (OR = 39.9, P < 0.01) and multiple tears (OR = 27.4, P < 0.01) to be independent risk factors for adverse aortic remodeling. Therefore, a branch originating from the false lumen and multiple tears were determined to be independent risk factors for adverse aortic remodeling after TEVAR in patients with Stanford type B aortic dissection.

Abstract
Hepatocellular carcinoma (HCC) is one of the most life-threatening malignancies worldwide. Defects in DNA repair genes may increase the risk of HCC. X-ray cross-complementing group 1 gene (XRCC1) is a major DNA repair gene involved in base excision re-pair. Recently, several studies have indicated that an association exists between XRCC1 polymorphism and HCC, particularly the Arg280His polymorphism. However, the data is inconsistent and incomplete. In this study, we conducted a meta-analysis to investigate the association between the XRCC1 Arg280His polymorphism and HCC risk. A total of 10 case-control studies included 1848 HCC cases and 1969 controls were examined in this analysis. Our results suggest that variant geno-types of the XRCC1 Arg280His gene are associated with a significantly increased risk of HCC in homozygote comparison (HisHis vs ArgArg, odds ratio, 1.55, 95% confidence interval, 1.10-2.18, P = 0.013); no het-erogeneity was observed (I2 = 0%). Our analysis suggests that the XRCC1 Arg280His polymorphism is associated with a higher risk of HCC.

Abstract
The TRAMO/SEATS program, combined with the Hodrick-Prescott (HP) filter, was used to detect trends and potential change points in time series of dissolved inorganic nitrogen (DIN) at three stations along the Yangtze River. The trend components were extracted, and two change points were successfully detected. The components revealed that DIN has been increasing at all the stations since the 1990s, although variations exist. Changes visible before 2002 illustrate the differences in agriculture development among regions upstream from the stations. The Three-Gorges Dam (TGD), which began to impound in 2003, led to years of different trends. The DIN concentration, which had been trending upward prior to that date, began a slightly downward trend because of NH4(+) depletion. Readings at the Yichang station revealed this trend most strongly; those at the Hankou station less so. The Datong station was far enough away from the TGD so that no obvious effects were seen.

Abstract
OBJECTIVE We sought to review the etiopathogenesis, diagnosis, and surgical options for 253 patients with portal vein thrombosis (PVT) undergoing orthotopic liver transplantation (OLT) to assess the the impact of PVT on outcomes. METHODS We retrospectively analyzed the data from 2508 adult patients undergoing 2614 OLTs in our center from September 1998 to July 2007. PVT was scored according to the operative findings and Yerdel grading of PVT. No prisoners were used as donors for this study. RESULTS Two hundred fifty-three patients were diagnosed with PVT (10.09%): there were 104 grade I; 114, grade II; 29, grade III; and 6, grade IV PVT. Sex and previous splenectomy increased the risk for PVT. In grade I and II cases, we performed simple thrombectomy, eversion thrombectomy, or improved eversion thrombectomy (IET, innovated by our center), producing smooth postoperative recoveries with a 0% in-hospitality mortality. In grade III cases, 18 underwent successful IET. Of 11 subjects who had eversion thrombectomy, six failed, and the distal superior mesentery vein or dilated splanchnic collateral tributary had to be used as the inflow vessel in four patients, and portal vein arterialization were performed in the other two patients, all of whom experienced a smooth postoperative recovery except one who died of hepatic failure and pulmonary infection 2 weeks after the operation. The in-hospitality mortality was 3.45%. In grade IV cases, three underwent successful IET, but another three cases failed, with two of them requiring a renal vein as the inflow vessel, and other one undergoing portocaval hemitransposition, with one postoperative death due to hepatic failure and another of cancer recurrence, an in-hospitality mortality rate of 33.33%. The transfusion requirement among PVT patients was significantly higher than that in non-PVT patients (9.32 +/- 3.12 U vs 6.02 +/- 2.40 U; P < .01). Blood loss in PVT patients who underwent the IET technique was significantly lower than that for an eversion thrombectomy (2800.36 +/- 930.52 mL vs 5700.21 +/- 162.50 mL P < .05). The overall actuarial 1-year survival rate in PVT patients was similar to the controls (86.56% vs 89.40%; P > .05). CONCLUSION OLT was successfully performed for PVT patients. The grade of PVT decided the surgical strategy. Similar 1-year survival rates were attained between PVT patients and controls undergoing OLT.

Abstract
BACKGROUND To investigate the molecular mechanism of the synergistic effects of human papillomavirus (HPV) and phorbal esters (TPA) in cell transformation. METHODS The expression of oncogenes and anti-oncogenes in 293 cell line treated with HPV and TPA was studied by Southern Blot and RNA dot blot. RESULTS It was found that the synergistic effect induced the amplification of c-myc (4-8 times), increased expressing level of c-erbB-2 (32-64 times) and decreased expressing level of p16(1/4-1/8). CONCLUSION The above results show that the synergistic effect has an important role in development of carcinoma.

Abstract
AIM To investigate the role of human papillomavirus (HPV) HPV16/18 E6 oncogene in the carcinogenesis of esophageal cell carcinoma (ESCC). MATERIALS AND METHODS Tissue microarray (TMA) block was constructed from 60 cases of paraffin-embedded ESCC tissues and pair-matched controls (adjacent normal epithelium). Immunohistochemistry (IHC) methods were applied to detect the expression of HPV16/18 E6, p53, p21(WAF1), MDM2, Ki67 and cyclin D1 proteins on TMA slides. In situ hybridization (ISH) targeting HPV gene was also used. RESULTS In ESCC samples, 18.3% (11/60) were revealed HPV16/18 E6 positive by IHC, while 40.0% (24/60) HPV positive by ISH; HPV16/18 E6 expression was significantly higher than that of control samples. In ESCC samples, the expressions of p53, p21(WAF1), Cyclin D1, MDM2 and Ki67 were recorded in 60.0% (36/60), 40.0% (24/60), 51.7% (31/60), 65.0% (39/60) and 88.3% (53/60) cases respectively, In ESCC samples, p53, MDM2 and Ki67 expression correlated with the HPV16/18 E6 expression (p less, similar 0.01), p21(WAF1) expression - with these of MDM2 and cyclin D1 (p less, similar 0.01) whilst expression of Ki67 - with ESCC grade (p less, similar 0.01). CONCLUSION HPV might be one of etiological factor of esophageal carcinoma in Shantou, China. p53, MDM2 proteins may play important roles in the pathogenesis of HPV-associated ESCC.

Abstract
By partial least squares (PLS) regression analysis, a quantitative structure-property relationship (QSPR) model was developed for photodegradation half-life (t1/2) of polychlorinated biphenyls (PCBs) in n-hexane solution under UV irradiation. Quantum chemical descriptors computed by PM3 Hamiltonian were used as predictor variables. The cross-validated value for the optimal QSPR model was 0.589, indicating good predictive capability for log t1/2 values of PCBs in n-hexane. The QSPR results show that standard heat of formation (DeltaHf), total energy (TE), and molecular weight (Mw) have dominant effect on t1/2 values of PCBs in n-hexane. Increasing DeltaHf and TE values or decreasing Mw values of the PCBs leads to decrease of log t1/2 values. In addition, increasing the largest negative atomic charge on a carbon atom and dipole moment of the PCBs leads to decrease of log t1/2 values.

Abstract
Fascin, an actin-bundling protein, induces membrane protrusions and increases cell motility in various transformed cells. The overexpression of fascin in esophageal squamous cell carcinoma (ESCC) has been described only recently, but the roles and mechanism still remained unclear. Here, by using RNA interference (RNAi), we have stably silenced the expression of the fascin in EC109 cells, an ESCC cell line. Down-regulation of fascin resulted in a suppression of cell proliferation and as well as a decrease in cell invasiveness. Furthermore, we revealed that fascin might have functions in regulating tumor growth in vivo. The effect of fascin on cell invasiveness correlated with the activation of matrix metalloproteases such as MMP-2 and MMP-9. We examined that fascin down-expression also led to a decrease of c-erbB-2 and beta-catenin at the protein level. These results suggested that fascin might play crucial roles in regulating neoplasm progression of ESCC.

Abstract
AIM: To explore the etiologic role of HPV infection in esophageal carcinoma, and the association of HPV-16 E6 with the nuclear matrix of carcinoma cells.
METHODS: Two esophageal carcinoma cell lines, EC/CUHK1 and EC/CUHK2, were tested for HPV-16 E6 subgenetic fragment by polymer a se chain reaction amplification of virus DNA associated nuclear matrix. RT-PCR and immunocytochemistry were also used to visualize the expression of E6 subgene in the cells.
RESULTS: The HPV-16 E6 subgenetic fragment was found to be present in nuclear matrix-associated DNA, E6 oncoprotein localized in the nucleus where it is tightly associated with nuclear matrix after sequential extraction in EC/CUHK2 cells. It was not detected, however, in EC/CUHK1 cells.
CONCLUSION: The interaction between HPV-16 E6 and nuclear matrix may contribute to the virus induced carcinogenesis in esophageal carcinoma.

Abstract
To examine certain characteristics of multistep carcinogenesis, we studied telomerase activity and malignant phenotypes in the immortal, premalignant and malignant stages of esophageal epithelial cells induced by HPV. An immortalized human fetal esophageal epithelial cell line (SHEE) was induced by E6E7 genes of human papillomavirus (HPV) type 18. Cells in the 10th passage, (SHEE10), 31st passage (SHEE31), 61st passage (SHEE61) and SHEE61A which were selected and expanded from anchorage-independent growth colonies of SHEE61, were examined as follows: cell morphology by electron-microscopy; the cell cycle by flow cytometry, telomerase activity by TRAP assay, tumorigenic detection including anchorage-independent growth by soft agar culture and tumor formation by inoculating cells into SCID and nude mice, and detection of HPV18 E6E7 oncoprotein by Western blot. The morphology of the SHEE10 cells exhibited good differentiation, the SHEE60 and SHEE61A cells were relatively poorly differentiated, and the SHEE31 cells were differentiated in two distinct ways. The telomerase was activated in SHEE31, SHEE61 and SHEE61A, but not in SHEE10 cells. SHEE61 and SHEE61A cells were weakened in contact-inhibition and increased in anchorage-independent growth. Inoculated into SCID and nude mice, the cells of the earlier two passages could not develop tumors; the SHEE61 developed one tumor in four SCID mice, but not in nude mice, and the SHEE61A cells developed tumors in both strains of immunodeficient mice. HPV18 E6E7 DNA detection by Western blotting was positive in all cell passages. In the process of carcinogenesis by HPV, the cells of SHEE31 are in an immortalized state with telomerase activity. The fact that SHEE61 cells remained immortalized and also demonstrated anchorage-independent growth, reveals premalignant character; the cells of SHEE61A exhibited malignant transformation with tumor formation in mice. The results revealed that the telomerase activity, anchorage-independent growth and tumor formation in nude mice are the indicators for immortalization, premalignancy and malignancy, respectively.

Abstract
E-cadherin, a cell adhesion molecule, is regarded as an invasion-suppressor molecule and a prognostic marker in many types of human cancers. Downregulation of E-cadherin is common in esophageal carcinoma and is associated with an increase in invasive and metastatic potential. To study the mechanisms responsible for inactivation of this gene in esophageal squamous cell carcinoma (ESCC), we investigated the methylation status around the 5' promoter region of E-cadherin gene of six ESCC cell lines by methylation-specific polymerase chain reaction, and compared it with E-cadherin protein and mRNA expression. We also studied the methylation status of 20 ESCC clinical specimens. Methylation was noted in four of the six cell lines (one fully methylated and three partially methylated). The completely methylated cell line lacked E-cadherin protein expression and mRNA transcription. E-cadherin expression and transcription were reduced in a partially methylated cell line but preserved in the other partially methylated cell lines. Treatment of E-cadherin-negative carcinoma cells with the demethylating agent, 5-aza-2'-deoxycytidine, induced re-expression of the gene. A high frequency of methylation (16/20, 80%) was also noted in the 20 ESCC clinical samples. Our results indicate that 5' CpG island methylation is common in esophageal carcinoma and may play an important role in downregulation of E-cadherin.

Abstract
AIM To examine the effects of microinjection of melatonin and its receptor antagonists into the anterior hypothalamic area (AHA) on blood pressure (BP) and heart rate (HR) in normotensive and stress-induced hypertensive rats. METHODS Melatonin and its receptor antagonists were microinjected into the AHA, then BP, mean arterial pressure (MAP), and HR were synchronously recorded. RESULTS Microinjection of melatonin produced a fall in MAP. Prazosin, an antagonist of melatonin ML2 receptor, could not antagonize the depressive response induced by melatonin. While luzindole, a competitive antagonist of melatonin ML1 receptor, was able to almost completely prevented the depressive response induced by injection of melatonin. CONCLUSION Melatonin acts as a hypotensive factor and the effects are mainly due to activation of ML1 receptors in rat brain, and the AHA may be one of the important central areas where melatonin can exert modulatory effects on BP and HR.

Abstract
We studied cytogenesis, telomere and telomerase, and c-myc, ras, bcl-2, and p53 genes of cells in the progressive process of immortal epithelial cells from embryonic esophagus induced by human papillomavirus (HPV). The SHEE cell line, established by us, consist of immortalized epithelial cells from the embryonic esophagus induced by genes E6E7 of HPV type 18. It was in initial malignant transformation when cultivated over 60 passages without co-carcinogens. Cells of the 10th, 31st, and 60th passages were represented in the progressive process within the immortal period. In these three stages of the cell line, the modal number of chromosome and karyotypes were analyzed. The telomere length was assayed by Southern blot methods, and the telomerase activity was analyzed by hTR and hTERT assay. C-myc, p53, bcl-2, ras genes were assayed by the multi-PCR method. The morphology of the 10th passage cells exhibited good differentiation, the 60th passage cells were relatively poorly differentiated, and the 31st passage cells differentiated in two distinct ways. The growth characteristics of the 31st and 60th passage cells were weakened at contact-inhibition and anchorage-dependent growth. Karyotypes of three cell passages belonged to hyperdiploid and hypotriploid with abnormal chromosomes +1, +3, +7, +9, +17, +18; del(1)(p32); der(4), t(4;?)(q31;?); der(5),t(5;?)(q31;?); der(13),t(13;13)(p11;q11) and others. Bimodal distribution of chromosomes with more aberrant chromosomes appeared in the 31st and 60th passage cells. Telomere length sharply shortened from normal fetal esophagus to the 10th and 31st passage step by step, but was stable from the 31st to the 60th passage and the telomerase activities measured were expressed at late two passages. p53 mutant was positive in three passages, c-myc was positive in the 31st and the 60th passage K-ras only in the last. The results reveal that changes of chromosomes, telomere length, telomerase activity and certain gene expressions are important events of HPV-immortalized esophageal epithelium cells. All of these changes occurred in dynamic progressive process. This cell line may be useful for the elucidation of the genetic mechanism of cellular immortalization.

Abstract
The study of the radionuclide distribution in sediment is a very important aspect in environmental impact of the low level radioactive liquid waste (LLW) from coastal nuclear facilities or nuclear power plant. Even now we do not know much about it. In this paper, a simple and useful method is put forward and it is used to estimate the nuclide distribution in sediment. The result showed that the LLW from nuclear facility or nuclear power plant will do a little harm to the sediment nearby. But the harm is not very serious. Much works have to be done before full understanding of the situation.

Abstract
Accumulation of poly-beta-hydroxybutyrate (PHB) by photoautotrophic microorganisms makes it possible to reduce the production cost of PHB. The Synechocystis sp. PCC6803 cells grown in BG11 medium under balanced, nitrogen-starved or phosphorus-starved conditions were observed by transmission electron microscope. Many electron-transparent granules in the nitrogen-starved cells had a diameter up to 0.8 micron. In contrast, the number of granules in the normally cultured cells decreased obviously and only zero to three much smaller granules were in each cell. These granules were similar to those in bacteria capable of synthesizing PHB. They were proved to be PHB by gas chromatography after subjecting the cells to methanolysis. Effects of glucose as carbon source and light intensity on PHB accumulation in Synechocystis sp. PCC6803 under nitrogen-starved cultivation were further studied. Glucose and illumination promoted cell growth but did not favor PHB synthesis. After 7 days of growth under nitrogen-starved photoautotrophic conditions, the intracellular level of PHB was up to 4.1% of cellular dry weight and the PHB concentration in the culture broth was 27 mg/l.

Abstract
Immobilized metal ion affinity chromatography (IMAC) has shown promise of isolating desired proteins from a mixture based on their difference of affinity for chelated metal ions. With its technological superiority, such as large adsorption capacity, mild separation condition, simple ligands and wide applications, IMAC has become powerful tool for biotechnological products separation, such as proteins, amino acids and gene products. In spite of many sophisticated applications for IMAC, the theoretical analysis of Immobilized metal chromatography has remained insufficient. In this paper, the eluted efficiencies of bovine serum albumin (BSA) in a single-component system under different elution conditions are studied. The effects of several elution factors, such as pH value, ammonium concentration and anion species on protein separation are studied. Comparing the elution data of BSA in IDA-Cu and IDA-Zn columns, the different ability of affinity between metal ions and proteins is found. In addition, the elution behaviors of different proteins are investigated. This work facilitates the further research in separation of real systems.

Abstract
OBJECTIVE To explore a method to repair severe radiation-induced ulcer and evaluate its clinical effects. METHODS From August 1988 to December 1998, 12 cases of severe radiation-induced ulcer were treated by muscular or musculocutaneous flap transfer, which included 1 case of pectoralis major muscular flap, 3 cases of three-lobed transverse rectus abdominis musculocutaneous flap, 2 cases of latissimus dorsi musculocutaneous flap, 1 case of tensor fascia lata musculocutaneous flap, 1 case of longitudinal rectus abdominis musculocutaneous and tensor fascia lata musculocutaneous flap, 1 case of gastrocnemius muscular flap, 1 case of gluteus major musculocutaneous flap, huge filleted musculocutaneous flap from lower limbs in 1 case and from upper limbs in 1 cases. RESULTS All the flaps survived. Primary healing occurred in 9 cases and secondary healing in 3 cases. The extensive multiple ulcers in 2 cases were repaired with filleted limb musculocutaneous flap, and patients were saved. And in other 3 cases, the chest wall defect as the result of radionecrosis were repaired with simultaneous breast reconstruction. CONCLUSION Muscular or musculocutaneous flaps have abundant blood supply, they are ideal tissue to fill the cavity and repair the defect, especially in repairing severe radiation-induced ulcers.
