Objective To evaluate the effectiveness of free highly active antiretroviral therapy (HAART) in adult infected with human immunodeficiency virus (HIV)/ acquired immune deficiency syndrome (AIDS) patients in Dehong area. Methods Clinical data of 1039 adult HIV/AIDS patients from five counties/cities in Dehong area who initiated HAART during the period from July 1st 2004 to June 30th 2008 were retrospectively analyzed to examine their virological and immunological responses to HAART. Data were analyzed by Chi-squared test or F test. Results Among the 1039 HIV/AIDS cases, 611 were males and 428 were females. The mean age was (37.0±9.9) years and the mean treatment duration was (22. 41 ± 12. 69) months. Complete viral suppression (HIV viral load＜50 copy/mL) was achieved in 781 cases (75. 17%). The percentage of patients achieving complete viral suppression rates were 76.95%, 76.49%, 70.65% and 77. 73% in patients treated for 6-12,13-24, 25-36 and more than 37 months, respectively (x2=8.646, P=0.194). The meanCD4+ T cell counts were (164.93±118.05) × 106/L at baseline, and (330.85±201.73) × 106/L, (356.24±205.49) × 106/L, (434.53±250.65) × 106/L and (396.31±202.62) × 106/L in patients treated for 6- 12, 13-24, 25-36 and more than 37 months, respectively. CD4- T cell counts were significantly different in patients treated for 6-12 and 13-24 months (F= 19. 423 , P＜0. 01). Successful immune reconstitution was achieved in 927 ( 90.88 % ) cases. Seven hundred and seventeen (70.29% ) cases achieved both virological suppression and immunological reconstitution with HAART, whereas 40 cases (3. 92%) failed to achieve both virological and immunological responses. Conclusion HIV/AIDS patients in Dehong area show good virological and immunological responses to HAART.

Objective To investigate the nutritional risks in hospitalized patients with liver diseases and work out nursing countermeasures.Methods Forty patients with liver cirrhosis, 40 patients with primary liver cancer and another 40 revisiting after liver transplantation involved in the investigation with a self-designed general information questionnaire and the nutritional risk screening 2002. The three groups were compared in terms of nutritional risks.Results Among the total 120 patients,38.3%(46/120)of them took the nutritional risk and even 12.5%(15/120)had the risk of undernourishment.The risk in the patients with liver cirrhosis was higher than that in the other two groups(χ2=9.899 and 11.4299 and P=0.002 and 0.001,respectively).Conclusions The nursing staffs should pay attention to the nutritional status of patients with liver diseases, especially the patients with liver cirrhosis.It is necessary to take effective measures in order to improve the nutritional status of the patients to reduce the nutritional risks.

ObjectiveTo assess the value of passive leg raising (PLR) test in predicting fluid responsiveness in patients with sepsis-induced cardiac dysfunction.Methods A prospective observational cohort study was conducted. Thirty-eight patients under mechanical ventilation suffering from sepsis-induced cardiac dysfunction admitted to Department of Surgical Intensive Care Unit of First Affiliated Hospital of Sun Yat-Sen University from September 2013 to July 2014 were enrolled. The patients were studied in four phases: before PLR (semi-recumbent position with the trunk in 45°), PLR (the lower limbs were raised to a 45° angle while the trunk was in a supine position), before volume expansion (VE, return to the semi-recumbent position), and VE with infusing of 250 mL 5% albumin within 30 minutes. Hemodynamic parameters were recorded in every phase. The patients were classified into two groups according to their response to VE: responders (at least a 15% increase in stroke volume,ΔSVVE≥15%), and non-responders. The correlations among all changes in hemodynamic parameters were analyzed by linear correlation analysis, and the receiver operating characteristic curve (ROC) was plotted to assess the value of hemodynamic parameters before and after PLR in predicting fluid responsiveness.Results Of 38 patients, 25 patients were responders, and 13 non-responders. There was no significant difference in the baseline and hemodynamic parameters at semi-recumbent position between the two groups. The changes in SV and cardiac output (CO) after PLR (ΔSVPLR andΔCOPLR) were significantly higher in responders than those of non-responders [ΔSVPLR: (14.7±5.7)%vs. (6.4±5.3)%,t = 4.304,P = 0.000;ΔCOPLR: (11.2±7.5)% vs. (3.4±2.3)%,t = 3.454,P = 0.001], but there was no significant difference in the changes in systolic blood pressure, mean arterial pressure, pulse pressure, and heart rate after PLR (ΔSBPPLR,ΔMAPPLR,ΔPPPLR andΔHRPLR) between two groups.ΔSVVE in responders was significantly higher than that of the non-responders [(20.8±5.5) % vs. (5.0±3.7) %,t = 8.347,P = 0.000]. It was shown by correlation analysis thatΔSVPLR was positively correlated withΔSVVE (r = 0.593,P = 0.000),ΔCOPLR was positively correlated withΔSVVE (r = 0.494,P = 0.002). The area under ROC curve (AUC) ofΔSVPLR≥8.1% for predicting fluid responsiveness was 0.860±0.062 (P = 0.000), with sensitivity of 92.0% and specificity of 70.0%; the AUC ofΔCOPLR≥5.6% for predicting fluid responsiveness was 0.840±0.070 (P = 0.000), with sensitivity of 84.0%and specificity of 76.9%; the AUC ofΔMAPPLR≥6.9% for predicting fluid responsiveness was 0.662±0.089, with sensitivity of 68.0% and specificity of 76.9%; the AUC ofΔSBPPLR≥6.4% for predicting fluid responsiveness was 0.628±0.098, with sensitivity of 76.0% and specificity of 61.5%; the AUC ofΔPPPLR≥6.2% for predicting fluid responsiveness was 0.502±0.094, with sensitivity of 56.0% and specificity of 53.8%; the AUC ofΔHRPLR≥-1.7%for predicting fluid responsiveness was 0.457±0.100, with sensitivity of 56.0% and specificity of 46.2%.Conclusion In patients with sepsis-induced cardiac dysfunction, changes in SV and CO induced by PLR are accurate indices for predicting fluid responsiveness, but the changes in HR, MAP, SBP and PP cannot predict the fluid responsiveness.

OBJECTIVETo compare follow-up and administration of HIV-infected local Chinese and Burmese in Dehong prefecture of Yunnan province, for scientific development of prevention and control measures.

METHODS14 270 HIV-infected local Chinese and 5 436 HIV-infected Burmese reported from 1989 to December 31, 2013 in Dehong prefecture were recruited as the subjects of study, comparing the differences of follow-up and management, CD4⁺ T lymphocyte count tests and antiretroviral therapy (ART) between the two groups.

RESULTSThe proportion of HIV-infected Burmese identified in Dehong prefecture was 27.6% (5 436/19 706) during 1989-2013. The number had been growing rapidly from 17.1% in 1989-2003, 12.4% in 2004 and 14.7% in 2005 to over 51.4% in 2012, hitting 59.4% in 2013 (trends χ² = 1 732.84, P < 0.000 1). The proportion of HIV-infected Burmese among case reports of various characteristics kept rising over the years. By the end of 2013, 8 095 HIV-infected local Dehong residents and 5 326 HIV-infected Burmese were still alive. 95.8% of them were under follow-up, 88.5% having CD4⁺ T lymphocyte count tests, and 78.3% under ART. Among the HIV-infected B urmese, only 19.2% of them were under follow-up, 13.0% having CD4⁺ T lymphocyte count tests, and 6.1% under ART, significantly lower than the local Dehong residents (P < 0.000 1).

CONCLUSIONThe proportion of follow-up and administration, CD4⁺ T lymphocyte count tests, and ART of HIV-infected Burmese was low in Dehong prefecture, Yunnan province, which called for more effective follow-up and administration measures.

OBJECTIVETo examine the proportion and influencing factors on HIV-infected individuals who rejecting the antiretroviral therapy among all the HIV positives, in Dehong prefecture, Yunnan province.

METHODSA cross-sectional analysis was conducted on all the local HIV-infected survivals aged over 16 year old who refused to receive antiretroviral therapy (ART) by the end of 2013 in Dehong prefecture.

RESULTSThe proportion of those rejecting the ART among HIV-infected survivals and aged over 16 years old in Dehong prefecture, was 7.4% (605/8 136). Factors related to the 'rejection' among the 605 refusals would include: being male (72.9%), aged 31-45 years (57.2%), peasants (75.4%), married (52.2%), with minor ethnicity (41.3%), illiterate or only having primary school education (58.7%), infected through sexual contacts (61.2%), and with CD4(+)T cell counts >350 cells/mm(3) (66.6%). Data from the multiple logistic regression analysis indicated that rejecting the ART was significantly associated with areas, gender, age, ethnicity and CD4(+)T cell counts of the HIV patients. Those who were from Yingjiang county, female, aged 31-45 years old had lower proportions of ART refusals than those who were from Ruili city, male, aged ≤30 year old. Those who were of Dai minority and had no records on CD4(+)T cell counts, had higher proportions of ART refusals than those who were of Han ethnicity and had CD4(+)T cell counts ≤350 cells/mm(3). Reasons for the 605 HIV-infected patients with rejection to the ART would include fear of disclosure of HIV infection status (84, 13.9%), misunderstandings of the effectiveness and side effects of ART (111, 18.3%), self-realized wellness(340, 56.2%) and others (70, 11.6%). Of them, reasons for the 181 patients with CD4(+)T cell counts ≤350 cells/mm(3) that rejecting ART would include fearfulness on the disclosure of HIV infection status(40, 22.1%), misunderstandings of the effectiveness and side effects of ART (36, 19.9%), self-realized wellness (84, 46.4%) and others (21, 11.6%). Among those who rejected ART, reasons for that would vary by areas, gender, age, marital status and routes of HIV transmission, according to the results from Chi-squared tests.

CONCLUSIONA substantial proportion of HIV-infected individuals rejected ART in Dehong prefecture of Yunnan province. It was urgently needed to enhance health education programs of ART tailored for those HIV-infected patients, according to different characteristics and reasons for rejection, so as to promote the ART in this prefecture.

ObjectiveTo understand the epidemiological characteristics and trends of sexually transmitted diseases （STDs） in Dehong Prefecture， Yunnan Province from 2010 to 2022， so as to provide a basis for the prevention and control of STDs in Dehong Prefecture. MethodsThe 2010‒2022 epidemic cards of STD cases in Dehong Prefecture were downloaded from the China Disease Control and Prevention Information System， and descriptive analysis of the incidence rate and demographic characteristics by disease type was conducted. The syphilis screening data of various populations in Dehong Prefecture between 2014 and 2022 were obtained from the National STD Control and Management Information System， and the syphilis positivity rates of key populations were calculated. ResultsA total of 18 225 STD cases were reported in Dehong Prefecture from 2010 to 2022， and the reported incidence rate increased from 17.1/10⁵ in 2010 to 172.0/10⁵ in 2022， showing an increasing trend （χ²_trend=42.9， P<0.001）. The number of reported cases of gonorrhea， syphilis， condyloma acuminatum， genital chlamydia infection， and genital herpes were 7 801 （42.8%）， 4 563 （25.0%）， 3 462 （18.8%）， 1 660 （9.1%）， and 775 （4.3%）， respectively. The majority of the reported STD cases were males （12 336 cases， 67.7%）， young adults aged 15 to <45 years （15 839 cases， 87.2%）， and farmers （9 230 cases， 50.7%）. The elderly group aged 65 years and over accounted for 10.5% of syphilis cases. Among different types of key populations， the highest syphilis positivity rate was found among men who have sex with men （10.1%）， followed by STD clinic attendees （8.1%）， and the syphilis positivity rates among clandestine prostitutes， voluntary counseling and testing population， drug addicts， and drug rehabilitation center/re-education through labor center population were 2.2%， 1.6%， 1.4%， and 1.3%， respectively. ConclusionFrom 2010 to 2022， the STD epidemic in Dehong Prefecture showed a rapidly increasing trend， with a higher incidence of gonorrhea and syphilis， and a higher syphilis positivity rate among men who have sex with men， drug addicts， clandestine prostitutes， and STD clinic patients. In the future， publicity， education and behavioral interventions for these groups should be strengthened to reduce the prevalence and transmission of STDs.

ObjectiveTo determine the characteristics， viral load and immunological status of HIV-infected persons and their spouses who became HIV-positive， and the reasons for HIV seroconversion in 55 HIV discordant couples in Dehong Dai and Jingpo Autonomous Prefecture （Dehong Prefecture）， Yunan Province. MethodsData on the 55 couples meeting the criteria of having a previously positive spouse were retrieved from the AIDS Integrated Prevention and Control Data Information System of the China Disease Control and Prevention Information System during 2015-2021. General socio-demographic information， age at diagnosis， exposure history， CD4⁺T lymphocyte count， and antiviral treatment were collected. Descriptive analysis and chi-square test were used to compare the distribution of pre-HIV-positive spouses and their HIV seroconverted spouses. ResultsA total of 55 spouses from HIV discordant couples had HIV seroconversion. Of them， 72.7% （40/55） of pre-HIV-positive spouses were husbands. The most recent CD4⁺T lymphocyte count in the pre-HIV-positive spouses was （328.31±246.27） cells·μL^-1 at the time of diagnosis of their seroconverted spouses， of which 36.3% （20/55） had a CD4⁺T lymphocyte count of less than 200 cells·μL^-1. Furthermore， of those pre-HIV-positive spouses with low CD4⁺T lymphocyte count， 45.0% （9/20） had an undetectable viral load， 15.0% （3/20） <400 copies·mL^-1， and 25.0%（5/20） ≥400 copies·mL^-1. Additionally， 16.4% （9/55） of the pre-HIV-positive spouses did not have a viral load test. The main reasons for HIV seroconversion among HIV-negative spouses in the discordant couples were poor condom use， poor compliance with antiviral therapy， and treatment discontinuation. ConclusionThe follow-up management of HIV discordant couples should be strengthened in Dehong Prefecture， especially the monitoring of viral load levels and immunological status of pre-HIV-positive spouses， to improve their compliance with antiviral therapy and reduce treatment discontinuation， which would effectively prevent and control HIV transmission between spouses.

ObjectiveTo investigate the demographic characteristics， high-risk behavior and first CD4⁺T cell（CD4 cell） counts among newly reported HIV-infected Burmese in Dehong Dai Jingpo Autonomous Prefecture （Dehong Prefecture） from 2019 to 2020. MethodsA cross-sectional survey was conducted among newly reported HIV-infected Burmese cases in Dehong Prefecture from 2019 to 2020 to collect related information and measure their first CD4 cell counts. ResultsAmong 1 228 HIV-infected Burmese cases， 846 （68.9%） were males and 382 （31.1%） were females； 445 （36.2%） were from Kachin， and 210（17.1%） were from Shan. Of them， 960 cases （78.2%） had participated in the first CD4 cell counts testing， and 405 cases （42.2%） had a first CD4 cell counts <350 cells·μL^-1. In the multivariable logistic regression analysis， age ≥30 years （adjusted OR=1.44， 95%CI： 1.07‒1.92） and history of illicit drug use in Myanmar （adjusted OR=0.41， 95%CI： 0.21‒0.79） were independently associated with first CD4 cell counts <350 cells·μL^-1. ConclusionThe first CD4 cell counts are generally low among newly reported HIV-infected Burmese in Dehong Prefecture， especially those aged ≥ 30 years and with a history of intravenous drug use in Myanmar. Therefore， early detection of HIV infection should be strengthened for timely intervention and treatment management among Burmese.

ObjectiveTo investigate the factors that influence the first CD4+T lymphocyte counts in newly reported HIV-infected cases aged 50 and above in Dehong Prefecture of Yunnan Province during 2016 to 2021， and to understand the patient immune status and disease progression so as to provide scientific basis for HIV prevention and control strategies in the future. MethodsData was collected from the national HIV/AIDS information system. Multivariate logistic regression was used for the analysis of factors affecting the first CD4+T lymphocyte counts. ResultsA total of 642 cases of HIV infection were newly reported， among them， 571 cases had CD4+T lymphocyte counts and 200 cases （35.03%） had CD4+T lymphocyte counts <200 cells·μL^-1. Patients who were in the 50-59 age group， male， divorced or widowed， and less educated were more likely to have CD4+T lymphocyte counts <200 cells·μL^-1. Compared with active testing consultants， forced reeducation through labor or drug rehabilitation cases were less likely to have CD4+T lymphocyte counts <200 cells·μL^-1. ConclusionThere is no obvious upward trend in newly reported HIV infected persons aged 50 years and above in Dehong Prefecture during 2016 to 2021. However， the situation of CD4+T lymphocyte counts <200 cells·μL^-1 is still serious. Attention should be paid to the key groups： male， Chinese nationality， farmers， Han nationality， married or divorced， junior high school education or below， and heterosexual transmission. It is necessary to strengthen the intervention in people aged 50 and above and improve the detection efficiency.

OBJECTIVETo understand HIV rival suppression and drug resistance (HIVDR) among AIDS patients who were receiving antiretroviral treatment (ART) in Dehong prefecture, Yunnan province.

METHODSAll AIDS patients who were aged over 15 years and with experience more than six months on ART by the end of 2012 in Dehong prefecture, were enrolled to receive testing for HIV viral load in plasma and genetic mutations associated with HIVDR.

RESULTSA total of 4 390 AIDS patients were qualified for the study according to the selection criteria, of whom 3 964 (90.3%) finally participated in the study. Among them, 2 307(58.2%) had CD₄(+) cell counts more than 350 cells/mm³. 3 169 (79.9%) patients showed undetectable plasma HIV viral load which was lower than the detection threshold. Those who had the following factors as:resided in Ruili city, being female, older than 45 years of age, married, heterosexually infected with HIV, having received ART more than 5 years, and CD₄(+) cell counts >500 cells/mm³, were more likely to have undetectable plasma virus load, with the differences statistically significant. 402 (10.1%) patients had plasma viral load ≥ 1 000 copies/ml, of whom 353 (87.8%) were successfully amplified and examined for HIVDR. Among them, 198 (56.1% ) were identified to bear genetic mutations associated with HIVDR. Most mutations were related to the resistance to nucleotide reverse transcriptase inhibitors (NNRTIs) or non-nucleotide reverse transcriptase inhibitors (NNRTIs), with M184V and K103N most frequently seen. 12 patients (3.4%) were found to have mutations resistant to protease inhibitors (PI). Data from multiple logistic regression analysis indicated that the period of receiving ART and the initial ART regimen could both significantly predict the occurrence of HIV resistance.

CONCLUSIONViral suppression was highly achieved among ART-prescribed AIDS patients in Dehong prefecture,Yunnan province. However, among those who did not show effective viral suppression, the proportion of HIVDR was high, underscoring the needs for health education so as to improve the adherence to drugs as well as for improving testing for viral load and HIVDR among AIDS patients.
