Objective To study the alternations of regulatory T cells in early HIV infected patients and its association with disease progression.Methods Fifty-one untreated HIV infected patients were enrolled and divided into 3 groups according to their infection time and CD+4 T cell levels(30 early HIV infected patients,15 typical progressors,6 AIDS patients).Twenty normal controls were enrolled.There were no significant differences between the age and sex among four groups.Blood was drawn by venipuncture from each subject in EDTA tubes and the levels of CD+4 CD+25 Foxp3 + regulatory T cells were detected by FACSAria flow-cytometry.Spearman correlation was used to detect association between CD+4 CD+25 Foxp3 + regulatory T cells and the absolute CD+4 T cells,viral load and activation of T cells.Results The levels of CD+4 CD+25Foxp3+ regulatory T cells showed the tendency of increasing tendency from normal control to early HIV infected patients,asymptomatic HIV infected patients and AIDS patients.Early HIV infected patients was significantly lower than that in AIDS group [3.79(2.11 - 5.43) % vs 8.09(4.90 - 8.90) %,Z = - 2.29,P = 0.022].The levels of CD+4 CD+25 Foxp3 + Treg cells were associated with viral set point(r = 0.479,P =0.038) and inversely associated with CD+4 T cells(r = -0.455,P =0.011) and closely associated with HLA-DR expression on CD+3 T cells(r = 0.533,P = 0.002).Conclusions The ratio of CD+4 CD+25 Foxp3 +regulatory T cells of early HIV infected patients was significantly increased and associated with viral set point and CD+4 T cell counts,which indicate that alternation of regulatory T cell may be an important factor contributing to the disease progression in early HIV infection.

Objective To evaluate the performance of the third generation ELISA and the fourth generation ELISA for HIV-1 diagnosis assays on acute and early HIV-1 infected samples.Methods Sixtyseven acute/early HIV-1 infected samples were collected from the follow-up gays with seroconversion in Shen Yang city and from clinical patients in the First Affiliated Hospital of China Medical University with incomplete HIV-1 specific bands in western blot between 2008 and 2010.Third generation ELISA,fourth generation ELISA,western blot and HIV-1 viral load detecting were used for detecting these samples.The sensitivity,consistency were compared between third generation ELISA and fourth generation ELISA to detect the seroconversion samples and the window periods were abserved.Chi square test was used for statistical analysis.Results In the 67 acute/early HIV-1 infected samples,56 were HIV positive and 11 were HIV negative by the third generation ELISA.The sensitivity of the third generation ELISA was 83.6％ (95％ CI:72.5％ -91.5％); 63 were HIV positive,1 was at gray zone and 3 were HIV negative by the fourth generation ELISA.The sensitivity of the fourth generation ELISA was 94.0％ (95％ CI:85.4％ -98.3％),higher than the third generation ELISA(x2 =16.1,P ＜0.01).The consistency of the third generation ELISA and the fourth generation ELISA was 86.6％ ( 95％ CI:76.0％ - 93.7％).The earliest third generation ELISA positive sample was the sample collected 16 days after HIV infection and the earliest fourth generation ELISA positive sample was the sample collected 9 days after HIV infection.There was significantly different on the window periods between the third generation ELISA and the fourth generation ELLSA Conclusion The fourth generation ELISA had a higher sensitivity and shorter window period on acute/early HIV infected samples than the third generation ELISA,which is more suitable for the HIV early infection screening on high risk populations.

ObjectiveTo investigate the influence of Mycobacterium tuberculosis (MTB) co-infection and other factors on the HIV replication level in antiretroviral treatment na(i)ve patients.MethodsSix hundred TB patients and 465 HIV infectors were recruited between April 2010 and September 2010.TB coinfections were diagnosed in HIV infected cases with chest X-ray,checking TB in sputum with anti-acid staining and culture of the sputum,histopatholo diagnosis and clinical diagnosis.HIV infections were screened in TB patients with the 3rd generation ELISA antibody test.Sixty-one antiretroviral treatment na(i)ve HIV/TB co-infectors and 34 HIV infectors with CD4 T cell count below 350 cells/μl were included in this study.Information about the demography,epidemiology and results of clinical diagnostic tests of HIV and TB was collected through pathography and questionnaires from all participants.HIV viral load were detected with COBAS AmpliPrep/COBAS TaqMan(R) System of Roche Company.ResultsThe viral load of HIV/TB co-infectors was (5.05±0.93) lg copies/ml,while the viral load of HIV infectors was (5.06±0.76) lg copies/ml,after control of age,race,marital status,education,route of HIV infection,HIV clade and CD4 T cell count,there was no significant difference between the two groups (P=0.94).CRF01_AE HIV-1 infection was associated with higher HIV viral load compared with non CRF01_AE (OR=8.07,95％ CI 1.07-61.20,P=0.04).ConclusionNo obvious effect of MTB co-infection on HIV replication level of HIV infected cases with relatively low CD4 T cell count in Guangxi region,while the CRF01_AE HIV infected individuals showed higher viral load,we should raise concern on the monitoring and treatment on this population.

Objective To investigate the effect of HCV RNA on virological and immunological response to highly active antiretroviral therapy (HAART),liver function and blood lipid levels in HIV/HCV co-infected patients.Methods In a cohort study,275 HIV/HCV co-infected former blood donors receiving HAART were followed up every six month in Henan province in China.HCV RNA,HIV RNA,CD+4 T cell counts,indexes of liver function and lipid levels were periodically tested.The differences of HIV viral load suppression,immunological response,liver injury and blood lipid levels between HCV RNA positive group and negative group were compared by x2 test and two independent-samples tests.Result There was no significant difference of HIV viral load suppression between HCV RNA positive group and HCV RNA negative group six-month treatment (45.6% vs.38.5% ,X2=1.150,P>0.05) and CD+4 T cell counts before (286 cells/μ1 vs.209 cells/μ1,Z=0.734,P=0.463)and after 6-month (310 cells/μ1 vs.362 cells/μl,Z=0.562,P=0.574) ,12-month(378 cells/μ1 vs.289 cells/μ1,Z=1.091,P=0.275),18-month(363 cells/μ1 vs.288 cells/μl,Z=1.435,P=0.151) ,24-month(413 cells/μ1 vs.348 cells/μ1,Z=0.939,P=0.348) HAART.The mean levels of serum ALT (55.0 U/L vs.29.5 U/L,Z=6.789,P<0.01),AST(46.0 U/L vs.33.0 U/L,Z=4.890,P<0.01)、TBIL(9.3 mmol/L vs.7.2 mmol/L,Z=3.748,P<0.01)were significantly higher in HCV RNA positive group than that in HCV RNA negative group.HCV RNA was the independent variables associated with liver injury after HAART (aOR=3.8,P<0.01).The serum triglyceride level was higher in HCV RNA positive group than that in HCV RNA negative group(1.2 mmoL/L vs.1.4 mmol/L,Z=1.936,P=0.043) .The serum HDL level was higher in HCV RNA positive group than that in HCV RNA negative group (1.5 mmol/L vs.1.3 mmol/L,Z=2.251,P=0.024).Conclusions HCV RNA does not affect HIV virological responses to HAART and CD+4 T recovery.HCV RNA is an independent risk factor associated with liver injury in HIV/HCV co-infected patients receiving HAART,but appears to provide significant protection against HAART-ieduced hyperlipidemia.

Objective:To investigate the difference of curative effect between zero-profile bridge-shaped locking cage (ROI-C) and anterior cage combined with titanium plate fixation in the treatment of two-level and three-level cervical spondylotic myelopathy.Methods:A total of 85 patients (43 males and 42 females), aged 52.3±8.0 years (range from 28 to 66 years) with bi- and three-level cervical spondylotic myelopathy who received surgical treatment from June 2017 to October 2019 were retrospectively analyzed. There were 63 cases of two levels and 22 cases of three levels. 45 cases were treated with zero-profile bridge-shaped locking cage ROI-C (ROI-C group), and 40 cases with anterior cage combined with titanium plate fixation (titanium plate group). The main observation indicators include operation time, intraoperative blood loss, cervical Cobb angle, fusion segment Cobb angle, average intervertebral height, pain visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) Score and neck disability index (NDI).Results:All of 85 patients were followed up for 16.9±2.0 months (range 12 to 22 months). The operation time of two-level ROI-C group was 110.37±8.25 min, which was shorter than 139.5±10.54 min of titanium plate group; the intraoperative blood loss was 15.74±8.10 ml, which was less than 23.71±9.70 ml of titanium plate group; the operation time of three-level ROI-C group was 130.00±5.70 min, which was shorter than 162.83±5.59 min of titanium plate group, while the difference in the intraoperative blood loss between the two groups had no statistical significance. One year after operation, Cobb angle of cervical vertebra in double and three-level ROI-C groups were 15.31°±1.55° and 15.20°±0.42°, respectively, which were largerthan 11.23°±2.03° and 9.20°±1.14° before operation; in titanium plate group, they were 15.89°±1.13° and 16.08°±1.88°, which were higher than 11.25°±2.01° and 9.00°±1.60° before operation, and the differences had statistical significance. The differences between the two groups before operation and 1 year after operation had no statistical significance. One year after operation, the VAS scores of double and three-level ROI-C groups were 1.83±0.66 points and 2.60±0.52 points, respectively, which were less than the preoperative 7.49±0.51 points and 7.60±0.52 points; the titanium plate group was 1.79±0.50 points and 2.41±0.51 points, which were less than the preoperative 7.61±0.63 points and 7.42±0.52 points, and the differences had statistical significance. There was no significant difference between the two groups before operation and 1 year after operation. One year after operation, the JOA scores of double and three-level ROI-C groups were 15.00±0.84 points and 14.70±0.95 points, respectively, which were higher than the preoperative 7.20±0.87 points and 6.60±1.27 points; the scores of titanium plate group were 15.29±0.85 points and 14.83±0.58 points, which were higher than the preoperative 6.89±1.03 points and 6.92±0.67 points, and the differences had statistical significance. The differences between the two groups had no statistical significance. The postoperative JOA improvement rate was excellent. Postoperative dysphagia occurred in 1 case (2.22%, 1/45) in ROI-C group and 8 cases (20.00%, 8/40) in titanium plate group, and the difference in the incidence rate between two groups had statistical significance ( χ2=5.32, P=0.02). Conclusion:Both ROI-C and anterior cage combined with titanium plate fixation in the treatment of double and three-level cervical spondylotic myelopathy can achieve good short-term clinical efficacy, with shorter operation time and lower incidence rate of postoperative dysphagia using ROI-C.

Objective To observe the adverse effects of 0.01％ atropine sulfate eye drops on myopic children.Methods A prospective non-randomized controlled trial was conducted.Ninety-nine myopic children (99 right eyes) were randomly assigned to experimental group(55 cases) and control group(44 cases).Myopic children of experimental group wore completely corrected frame glasses,while 0.01％ atropine sulfate eye drop was dropped into each eye once a day before going to bed.Myopic children in control group only wore completely corrected frame glasses.The follow-up time was 4 months.Best corrected visual acuity (BCVA),intraocular pressure (IOP),change of pupil diameter (PD) and amplitude of accommodation,symptoms of discomfort after medication were observed.This study followed the Helsinki declaration and was approved by Ethic Committee of the First Affiliated Hospital of Zhengzhou University.Informed consent was signed by the parents of each patient.Results No significant differences were found in best corrected distance visual acuity (BCDVA),best corrected near visual acuity(BCNVA) and IOP between the two groups before and 4 months after treatment (BCDVA:Fgroup =3.880,P =0.112;Ftime =27.220,P =0.413;BCNVA:Fgroup =5.200,P =0.311;Ftime =38.200,P =0.116,IOP:Fgroup =12.350,P=0.214;Ftime =22.300,P =0.146).After 4 months treatment,the PD was (6.99 ±0.64) mm in the experimental group,which was significantly higher than that before treatment(P＜0.001).The PD of the experimental group was higher than that of the control group after 4 months treatment,and the difference was statistically significant (P＜0.01).The amplitude of accommodation in the experimental group was 14.01 ±3.98 after 4 months treatment.which was 1.20 D lower than that before treatment,the difference was statistically significant (P＜0.01).The amplitude of accommodation of the experimental group was lower than that of the control group after 4 months treatment,the difference was statistically significant (P ＜ 0.01).Four cases (8％) appeared photophobia symptoms.Two cases and 2 cases appeared photophobia for 1 week or 2 weeks,respectively.However this symptom would relieve after wear sunglasses or sunshade caps in outdoor activities.One case (2％) appeared ocular itching and swelling after 1 month treatment,but disappeared after withdrawal.There were no other uncomfortable symptoms such as near sight blurring.Conclusions In mainland of China,the BCDVA,BCNVA and IOP of myopic children are stable;the PD is dilated and the amplitude of accommodation is decreased slightly after 4 months treatment of 0.01％ atropine,and 10％ children appear photophobia,but do not affect their study and life.

Objective:To probe into the causes, reconstructive strategies, and repair outcomes of asymmetric eyelid configuration after blepharoplasty.Methods:All 73 patients (14 males and 59 females) with asymmetric double eyelid after blepharoplasty were recruited between July 2013 and June 2018 from Department of Plastic and Burns Surgery, West China Hospital, Sichuan University. The patients aged from 18 years to 42 years with the median age of 27 years. The new double eyelid line was designed pre-operation. Releasing subcutaneous adhesion of upper eyelid entirely, trimming inferior orbicularis oculi, adjusting and comparing the attachment position of bilateral levator aponeurosis were performed during surgery. Patients and surgeons marked the appearance of double eyelid both before and after repair operation, results of which were analyzed by t-test.Results:All 73 patients obtained improved double eyelid with primary healing. During follow-up from 8 to 12 months, repaired double eyelid showed satisfactory configuration with smooth natural double eyelid line and symmetric bilateral double eyelid. Of the 73 patients, 3 (4.1%) complaint rough double eyelid line, for whom re-fixation through small incision were adopted and no complication was observed during follow-up time. Scores by patients and surgeons were both significantly better after surgery.Conclusions:Analyzing the causes of asymmetric eyelid after double-eyelid blepharoplasty and repairing it contribute to aesthetic pleasing reconstructed double eyelid.
