Abstract
Macular telangiectasia type 2 (MacTel 2) is an idiopathic entity which is characterized by dilated capillary network near, or around, the fovea of the macula. The spectrums secondary to macular retinal vascular inflammation or obstruction are excluded. It is a binocular disease in general. MacTel 2 is now widely recognized as a macular neurodegenerative disease rather than a simple vascular disease. This article reviews the epidemiological features, clinical features, staging, special examinations, pathogenesis and treatment of MacTel 2. (Chin J Ophthalmol, 2019, 55:68-73).

Abstract
Objective: To investigate the effect of heterogeneous nuclear ribonucleoprotein K (hnRNP K) and its interaction with human papillomavirus 16 (HPV16) on cervical intraepithelial neoplasia (CIN). Methods: The participants included 67 women with normal cervix (NC), 69 women with CINⅠ and 68 women with CINⅡ/Ⅲ in a community cohort of pathologically diagnosed women established in Jiexiu of Shanxi province, from June 2014 to June 2015. A structured questionnaire was used to collect the demographic data of the subjects and the related factors of cervical lesions. Cervical exfoliated cells and cervical tissues from biopsy or surgery were selected. The infection status of HPV16 was detected by flow-through hybridization. The protein expression levels of hnRNP K were evaluated by Western blot. SPSS 23.0 software was used to collate and analyze the data. To study the differences in demographic characteristics, related factors, hnRNP K protein and HPV16 infection among NC, CINⅠand CINⅡ/Ⅲgroups, χ(2) test, trend χ(2) test, and Kruskal-Wallis H test were conducted. Multiple comparisons of hnRNP K protein in three groups were completed by using the Bonferroni method. The OR and its 95%CI of hnRNP K, HPV16 and CIN were calculated by using the unconditional logistic regression models. Two-way interactions between hnRNP K protein and HPV16 infection on CIN were analyzed by using additive model and related indicators. Results: HPV16 infection rates were 10.4% in women with normal cervix, 14.5% in women with CINⅠ and 41.2% in women with CINⅡ/Ⅲ, respectively. The differences among three groups were significant (P<0.001). Moreover, the infection rates of HPV16 gradually increased with the increasing severity of CIN (trend χ(2)=18.512, P<0.001). The differences in protein expression of hnRNP K among three groups were significant (H=48.138, P<0.001) and the expressionincreased with the development of cervical lesionss (trend χ(2)=21.765, P<0.001). Results from the interaction analysis indicated that there were additive effects between high expression of hnRNP K protein and HPV16 in CINⅡ/Ⅲ group compared with normal group (API=0.639, 95%CI: 0.083-1.196). In contrast, no such additive effect was found in CINⅠ group. Conclusions: HPV16 infection and over-expression of hnRNP K protein were associated with the increased risk of cervical intraepithelial neoplasia. There might be interaction between hnRNP K protein overexpression and HPV16 infection existed on the progress of CINⅡ/Ⅲ.

Abstract
Objective: To compare the clinical effects of modified double-lumen drainage tube and traditional silicone tube in external drainage of chronic subdural hematoma. Methods: Selected 49 patients suffering from chronic subdural hematoma hospitalized in the Department of Neurosurgery, the First Affiliated Hospital of Bengbu Medical College between July 2016 and June 2018 who underwent external drainage, and divided them randomly into experimental groups (using modified brain protection double lumen drainage tube in 23 cases) and control group (using traditional silicone drainage tube in 26 cases). Comparison of postoperative hematoma residual volume, the tube indwelling time, the numbers of drainage tube contact with brain tissue and arachnoid membrane, the numbers of infections, the numbers of postoperative epilepsy cases, and changes in Modified Rankin Scale scores between the two groups. Results: At the time of extubation, the residual amount of hematoma in the experimental group was (13±7) ml, and that in the control group was (17±8) ml. There was no significantly statistical difference in the residual amount of hematoma between the experimental group and the control group (P>0.05). The tube indwelling time of the experimental group was (2.0±0.9) days, and that of the control group was (2.7±0.8) days. The difference between the experimental group and the control group in the drainage tube indwelling time was statistically significant (P<0.05). No cases of drainage tube contact with brain tissue and/or arachnoid membrane appeared in the experimental group, and 7 cases of drainage tube contact with brain tissue or arachnoid membrane appeared in the control group. No infection occurred in both groups. No cases of epilepsy occurred in preoperative, and there were 0 cases of epilepsy in the experimental group and 1 case in the control group in postoperative. There were significantly statistical differences in each of the two groups in the modified Rankin scale before and after surgery (P<0.001), there was no significant difference in postoperative Modified Rankin Scale scores between the two groups. Conclusion: The modified brain protection double-lumen drainage tube has good drainage effect in the external drainage of chronic subdural hematoma, and the short tube retention time, causing fewer complications. It is a safe and effective tool for treating chronic subdural hematoma, and it is worthy of clinical promotion.

Abstract
Objective: To evaluate the surgical technique and outcomes of uteri retrieval from brain-dead multi-organ donors.This study is a preclinical research of human living uterine transplantation. Methods: From May, 2015 to May, 2017, four uteri retrieval procedures, characterized with radical hysterectomy and uterine vascular pedicles dissection, were performed in multi-organ brain-dead donors.The uterus was the third authorized organ after the kidney and liver retrieval procedures in the first two cases.The uterine pedicles included the uterus, ovaries, fallopian tubes, the upper one-third of the vagina and internal iliac vessels or external iliac vessels.The perfusion of the uterus was conducted after the retrieval for evaluating the availability, followed by histopathological examination of the uterine issues per 30 minutes. Results: Since the uterine vein was quite difficult to identify and dissect in the first two case, which result in the rupture of triple uterine veins.Therefore, the uterine venous vessels including uterine vein connected with internal iliac vein and internal iliac arteries were selected as vascular grafts and dissected successfully in the last two cases, which could be perfused with the mixture of 4 ℃ heparinized physiological saline through each artery because of shortening the surgical time and arranging the uterine procurement as the first authorized organ procedure.Mean (SD) operative time was 152.5±39.0 min (115-215 min, n=4). Conclusion: Our preliminary experience indicated that the uterus could be retrieved from the brain-dead multi-organ donors and transplanted to the recipient.The attempt of skeletonizing the uterine veins should be replaced by dissection of internal iliac vein.

Abstract
Objective: To investigate the clinical value of combined detection of serum miR-378 and miR-21 in gastric cancer (GC). Methods: Eighty-seven patients with GC and 78 patients with colorectal cancer(CRC) from National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences were selected, 83 individuals undergoing healthy physical examination were selected as the healthy controls. The levels of serum miR-378 and miR-21 were detected by quantitative real-time PCR (RT-qPCR) (result data were transformed as log2 for analysis). Results: Relative expression levels of miR-378 in the serum were -1.24, -3.25 and -2.73 in healthy controls, GC and CRC patients, respectively. Compared with the healthy controls, the levels of serum miR-378 were significantly decreased in GC and CRC patients (both P<0.05). Relative expression levels of miR-21 in the serum were 0.11, 2.34 and 2.47 in healthy controls, GC and CRC patients, respectively. Compared with the healthy controls, the levels of serum miR-21 were significantly up-regulated in GC and CRC patients (both P<0.05). Moreover, the serum level of miR-378 in GC patients was inversely associated with tumor clinical stage (P<0.05). However, the level of miR-21 showed no significant differences among patients with different clinical and pathological characteristics (all P>0.05). The area under the receiver operating characteristic curve (AUC), sensitivity and specificity of miRNA-378 to diagnose GC was 0.770, 82.0% and 66.0%, respectively, and were 0.900, 85.0%, and 88.0% of miR-21, respectively. The AUC, sensitivity and specificity of combined detection of serum miR-378 and miR-21 to diagnose GC were 0.930, 92.0% and 87.0%, respectively, while the AUC of combined detection of serum CEA and CA-199 was 0.767, the AUC of combined all of the four factors was 0.946. Conclusion: The combined detection of serum miR-378 and miR-21 have a certain effect on diagnosis of GC.

Abstract
Objective:To study the clinical features of patients with recurrent benign paroxysmal positional vertigo (BPPV) and to analyze potential related factors of recurrences.Method:Eighty patients who suffered recurrent BPPV were enrolled in this study. Patients were divided into three groups: young group (21 cases), middle-aged group (25 cases) and old-aged group (34 cases). Theclinical data including age, gender, pathological pattern and canal type of BPPV were collected. We further analyzed the efficacy of repositioning treatment for recurrent BPPV.Result:In this study, there are 62 cases of primary BPPV(77.50%) and 18 cases of secondary BPPV(22.50%). In patients with recurrent BPPV, the laterior semicircular canal BPPV and posterior semicircular canals BPPV were the most common, and there was no differences on the aspects of age and gender in the two groups of patients with recurrent HSC BPPV and PSC BPPV (P>0.05).Compared with the primary diagnosis, we found that 48.75% cases relapsed in the same semicircular canals, 21.25% cases relapsed in other canals of the same ear, and 30.00% cases relapsed in a different ear. In this study, 96.25% patients with recurrent BPPV were cured in a month and one-time reset success rate was 56.25%.Conclusion: The age, gender, pathological pattern and canal type show certain clinical features of recurrent BPPV. The evidence of long term of recurrence course and high variability of problematic location support the approval opinion based on new otolith.

Abstract
OBJECTIVES To determine the individual and combined influences of smoking and alcohol consumption on lipid profile in male adults in northwest rural China. DESIGN Cross-sectional study. METHODS In total, 4614 subjects were enrolled in the cross-sectional study, performed between 2008 and 2012. The present study examined males aged ≥18 years from northwest rural China (n = 707). Data on current smoking and drinking status were collected. Logistic regression was used to estimate the individual and combined influences of smoking and alcohol consumption on lipid profile. Age, ethnic group, educational background, smoking (or alcohol consumption), waist circumference, body mass index, blood pressure and fasting blood glucose were adjusted as confounders. RESULTS Total cholesterol (TC)/high-density lipoprotein cholesterol (HDL-C) ratio, triglycerides (TG)/HDL-C ratio, low-density lipoprotein cholesterol (LDL-C)/HDL-C ratio and visceral adiposity index (VAI) were significantly higher in smokers than in non-smokers, whereas HDL-C was lower in smokers. TG/HDL-C ratio, LDL-C/HDL-C ratio, TG, lipid accumulation product and VAI were significantly higher in drinkers than non-drinkers. After adjustment for confounders, significant relationships were observed between smoking status and any dyslipidemia, low HDL-C and high VAI (odds ratios [ORs]: 2.53 [95% confidence interval {CI}: 1.25-5.15], 6.13 [95% CI: 2.84-13.25] and 4.39 [95% CI: 2.02-9.54], respectively). The OR for any dyslipidaemia was 1.94 (95% CI: 1.09-3.48) for subjects who smoke and drank alcohol compared with subjects who did not smoke or drink alcohol. CONCLUSIONS Abnormalities in lipid profile are correlated with smoking and alcohol consumption, which calls for intervention strategies to prevent dyslipidaemia and control risk factors for cardiovascular disease.

Abstract
Objective: To investigate the role of PRDM1 gene inactivaion in the regulation of C-MYC in diffuse large B-cell lymphoma (DLBCL), and to explore the correlation of its immunophenotype and prognosis. Methods: 100 cases paraffin-embedded DLBCL tissues were collected from January 2009 to December 2015 at the First Affiliated Hospital of Xinjiang Medical University along with 20 cases of reactive proliferative lymph nodes as control. Immunohistochemical methods were used to detect the expression of CD20, CD10, MUM1, Ki-67, bcl-6, PRDM1/Blimp1, C-MYC and PAX5 protein. The tumors were classified into two subtypes according to Hans classification.The expression of PRDM1 and C-MYC gene in tumor group and control group was detected by reverse transcription PCR (RT-PCR) and the relationship between PRDM1 and C-MYC gene was analyzed.OCI-LY1 (GCB subtype) and OCI-LY3 (non-GCB subtype) cell lines were transfected with small interfering RNA by cationic liposome reagent transfection, and the expression of C-MYC in the transfected cell lines was detected by RT-PCR and Western blot. The Kaplan-Meier method was used to analyze the prognostic significance of PRDM1/Blimp1 and C-MYC at protein and mRNA levels. Results: There were 27 cases of GCB subtype and 73 cases of non-GCB subtype according to Hans classification. The positive expression of Blimp1 in DLBCL group and proliferative lymph nodes in control group was seen in 26(26.0%) and 20 cases(100%), respectively. There were 58 cases with high expression of PRDM1 at mRNA level, including 22 cases of GCB subtype and 36 cases non-GCB subtype, and the difference was statistically significant (P=0.004). There were differences in PRDM1 gene expression between the two immunological subtypes, serum lactate dehydrogenase (serum LDH) level, presence of B symptoms, tumor primary sites and other clinical pathological parameters, while C-MYC expression was different in gender, IPI score, and serum LDH levels. Upon PRDM1/Blimp1 gene silencing in the two cell lines, C-MYC protein and gene expression were up-regulated in the transfection group, compared with the blank control group and negative control group by reverse transcription PCR and Western blot analyses. Moreover, PRDM1 expression was significantly associated with C-MYC(χ(2)=7.648, P=0.006) at mRNA level. Conclusion: The up-regulation of C-MYC gene expression induced by PRDM1 inactivation in DLBCL may play an important role for the development of DLBCL.PRDM1 protein and mRNA are associated with immunophenotyping and PRDM1 mRNA is a marker of poor prognosis.

Abstract
Objective: To investigate the demographic characteristics, clinical features, diagnosis and treatment of patients with gout in China. Methods: Clinical data of 6 814 patients with gout from 100 hospitals in 27 provinces, municipalities or autonomous regions in China were collected and analyzed. Results: (1) The ratio of male to female in patients with gout was 14.7∶1. The mean age of onset was (48.8±15.1) years old. Mean serum urate level was (526.7±132.3) μmol/L. Patients' education background was of U-shaped distribution; (2) Hypertension was the most common comorbidity [15.8%(1 079/6 814)], then overweight or obesity [51.9%(3 536/6 814)]; (3) Alcohol and high-purine food intake were dominant triggering factors in men. The diagnosis of gout was made after onset in majority of patients with cardinal symptom arthralgia. Most patients had the disease less than 5 years, and the longer the course, the more flares in the previous year of entry; (4) Febuxostat was the mostly used urate-lowering medication. 20.7%(1 412/6 814), 10.8%(739/6 814) and 3.9%(265/6 814) of patients were followed up in 4 weeks, 12 weeks and 24 weeks after registration, and 18.9%(267/1 412), 29.1%(215/739) and 38.1%(101/265) of them reached the control target of serum urate levels, respectively. After treatment, patients' liver function was not affected, but serum creatinine levels decreased significantly. Conclusions: The proportion of gout patients who reach target serum urate level is very low. Further steps including education and survey need to be carried on.

Abstract
Objective: To investigate macular retinal and choroidal thickness and blood flow change using optical coherence tomography angiography after posterior scleral reinforcement (PSR) surgery. Methods: Prospective study. Twenty eyes of 10 patients with high myopia were enrolled in this open-label, single-treatment group and prospective study. Radial lines and Angio retina (3 mm×3 mm) module were performed for 20 eyes using Angio-vue optical coherence tomography (Avanti, Optovue) without pupil dilation, and best corrected visual acuity, spherical equivalent and axial length were compared before and 60 days after surgery. Retinal and choroidal thickness was measured in the fovea, 1 mm superior, 1 mm inferior, 1 mm nasal and 1 mm temporal to the fovea. Flow area, flow density and flow index were recorded using self-provided software in the superficial retina layer, deep retina layer, outer retina layer and choroid capillary layer, respectively. Statistical analysis was performed using SPSS 16.0. Data that followed normal distribution were compared with paired two-sample t-test, while others were compared with Wilcoxon signed rank test. Results: Of the patients participating in this preliminary study, the mean age was (35.5±4.2) years, and 50% were female. No significant difference was found between before and 60 days after PSR surgery in best corrected visual acuity (t=0.99, P=0.33), spherical equivalent (t=-1.89, P=0.07) and axial length (t=0.2, P=0.08). The retinal thickness in the fovea was thinner (Z=-2.58, P=0.01), while there was no significant difference in the 1 mm superior (t=0.44, P=0.67) , 1 mm inferior (t=0.05, P=0.96) , 1 mm nasal (Z=0.87, P=0.64) and 1 mm temporal (Z=-0.78, P=0.99) to the fovea. No significant difference was found in choroidal thickness (t=-0.12, P=0.87; t=-0.25, P=0.81. t=0.53, P=0.61; t=-0.91, P=0.38. t=1.2, P=0.25) before and after surgery. The postoperative flow density in the superficial and deep retinal layers (48.18±4.56% and 31.47±5.11%) was significantly increased (t=2.66, P=0.02; t=3.16, P=0.01) compared with pre-operation (33.82±4.33% and 14.29±3.89%). The postoperative flow index in the superficial and deep retina layers (0.044±0.005 and 0.025±0.005) was significantly increased (t=2.59, P=0.02. t=2.95, P=0.01) compared with pre-operation (0.028±0.004 and 0.010±0.003). The other flow measurements showed no significant difference. Conclusion: Retinal thickness decreased, and flow density and index increased in the superficial and deep retinal layers after PSR surgery. This suggested blood flow improvement in the macular region after PSR surgery in high myopic eyes. (Chin J Ophthalmol, 2017, 53:39-45).

Abstract
Objective: To investigate PRDM1 gene methylation status, immune classification and their prognostic significance in diffuse large B cell lymphoma (DLBCL). Methods: Immunohistochemical (IHC) staining for CD20, CD10, bcl-2, bcl-6, PRDM1/Blimp-1 and MUM1 was carried out in 100 cases of DLBCL specimens and 20 reactive lymphoid proliferation samples. All patients were classified into germinal center B cell-like (GCB) and activated B cell-like (ABC) subtype according to Hans' algorithmin. PRDM1 gene methylation was detected by methylation-specific PCR (MSP) and its relationship with clinicopathologic parameters was analyzed. OCI-Ly1 (GCB type) and OCI-Ly3 (ABC type) cell lines were transfected by Small interfering RNA(siRNA) with cationic lipid reagent transfection mediated, and the PRDM1/Blimp-1 expression in before and after transfected cell lines were detected with reverse transcription-PCR and Western blot methods. The relationship between PRDM1 gene methylation, clinicopathologic parameter and survival was analyzed using one-way analysis of variance. Results: One hundred patients were classified into 73 (73%) cases of GCB subtypes and 27 (27%) cases of ABC. PRDM1/Blimp-1 was expressed in 21 DLBCL and highly expressed in 20 reactive lymphoid proliferation. PRDM1 gene methylation was detected in 23% (23/100) of DLBCL, while no methylation was detected in all 20 reactive lymphoid proliferation. The difference of the PRDM1 methylation status between DLBCL and the control samples was statistically significant (P=0.004). However, there was no significant correlation between the PRDM1 gene methylation and clinicopathologic parameters (P>0.05). Reverse transcription-PCR and Western blot showed that PRDM1 gene expression was reduced in siRNA-induced group compared with blank control group and negative control group. One-way analysis of variance revealed that aged ≥60 years, performance status score above 3, and the presence of general symptoms were associated with significantly lower overall survival rate. Conclusions: PRDM1 gene silencing with aberrant CpG methylation is probably one of the critical events in the oncogenesis of DLBCL. This may have important implications as a candidate marker for diagnosis and targeted gene therapy. Meanwhile in vitro siRNA transfected OCI-Ly1 and OCI-Ly3 cell lines confirm that PRDM1 gene is a suppressor gene in DLBCL and may represent a novel therapeutic target.

Abstract
Objective: To study the clinical characteristics and prognosis of patients with persistent inflammation immunosuppression and catabolism syndrome (PICS) in ICU. Methods: A total of 126 patients admitted to ICU (ICU stay of more than 10 days, age≥18 years) between January 2014 to December 2014 were retrospectively studied.Data were collected from electronic medical records including demographics, underlying disease, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHEⅡ) score, Sequential Organ Failure Assessment (SOFA) score, laboratory parameters, ICU acquired infections and clinical outcome. Results: The overall incidence of PICS in ICU patients (ICU stay of more than 10 days) was 50.0%(63/126). There were no significant differences in baseline data such as gender, age, APACHEⅡscore, SOFA score and underlying diseases between the two groups(all P>0.05). Compared with the non-PICS group, there were more patients with gastrointestinal perforation in the PICS group (P=0.042), however, the medical or surgical admission did not differ between the two groups(P>0.05). During the stay in ICU, the PICS group showed a higher risk of developing acquired infections compared with the non-PICS group[PICS 63.5%(40/63) vs non-PICS 23.8%(15/63); P<0.001]. The infections were more caused by Candida in the PICS group than the non-PICS group [PICS 22.4%(11/49) vs non-PICS 2/17; P=0.003]. Moreover, the PICS group experienced longer stay in ICU[PICS(31.6±28.8) days vs non-PICS (20.4±11.3) days; P=0.0046] and higher ICU mortality [PICS 28.6%(18/63) vs non-PICS 6.3%(4/63), P=0.001]. Conclusion: PICS is a common manifestation of patients who stay in ICU more than 10 days, which is associated with high risk of ICU acquired infections, prolonged length of stay and high mortality.

Abstract
Objectives: To analyze RB1 gene mutation in retinoblastoma (RB) patients using gene capture technology. Methods: Experimental research. The clinical data of 17 RB patients were collected at Department of Ophthalmology, Peking University People's Hospital from June 2010 to Jun 2014. Peripheral blood samples of seventeen RB patients and their parents were collected and genomic DNA were extracted. DNA library from RB patients was mixed with designed gene capture probe of RB1 exons and its flanking sequences. The data were analyzed using bioinformatics software. To avoid the false positive, the abnormal sites were verified using the Sanger sequencing method. Results: Totally, there were 17 RB patients, including 12 males and 5 females, from 0.5 to 23 years old, average ages were (3.2±5.2) years old. Both eyes were involved in 6 patients. The other 11 cases were only one eye was attacked. Four RB patients were found to have germline mutations, among whom 2 had bilateral tumors and 2 had unilateral tumors. 2 novel missense mutations were identified, including 15(th) exon c.1408A>T (p. Ile470Phe) and c.1960G>C (p. Val654Leu) at 19(th) exon. No RB1 mutation was identified in any of their parents. We also identified 2 mutations reported previously. One is c.1030C>T termination mutation at 10(th) exon in a bilateral RB patients and his father, who was diagnosed with unilateral RB. The other is c.371-372delTA frame shift mutation at 3(rd) exon. No mutation was found in their parents. Conclusions: Two novel germline RB1 mutations were found using gene capture technology, which enriched RB1 mutations library.(Chin J Ophthalmol, 2017, 53: 455-459).

Abstract
The aim of this study was to examine the effects of different sources and levels of methionine (Met) on Heat shock proteins HSP70 expression and protein carbonylation in liver, HSP70 expression and malondialdehyde (MDA) concentration in intestine under heat stress conditions during summer. A total of 720 (4 days old) Peking ducks were placed 20 per pen into six replicates for each of the six treatments with a 2 × 3 factorial arrangement, such that two sources of Met (DL-methionine [DLM] and DL-2-hydroxy-4-methylthiobutyrate [HMTBA] were supplemented at three different levels (0.05%, 0.20%, or 0.35% on as-fed basis respectively). The experiment was divided into a starter (day 4-16) and a grower (day 17-35) period. Diet supplemented with 0.35% Met significantly up-regulated the HSP70 mRNA expression in duodenum, jejunum and ileum on day 16 and 35 as well as in liver on day 35 (p < .05) of ducks. HMTBA-supplemented diets increased the HSP70 mRNA expression in duodenum, jejunum, ileum and liver on day 35 (p < .01). An increased MDA concentration was detected in jejunum of birds in 0.35% DLM-supplemented treatment on day 16 (p < .05). And decreased protein carbonylation concentration was found in DLM-supplemented treatment on day 16 (p < .01). The birds fed with 0.35% Met supplemental diet displayed lower hepatic protein carbonylation on day 16 (p < .05). In conclusion, supplementation of 0.35% Met in the duck diet showed up-regulated HSP70 expression in small intestine and liver, which may provide new perspective to the mechanism of Met function. At the same time, DLM supplemented in diet may ameliorate oxidative status of liver, while HMTBA supplementation may partially improve the intestinal oxidative status of Peking ducks.

Abstract
Objective: To detect the changes in the immune function of opioid-dependent subjects during the withdrawal stage through the administration of Jitai tablet. Methods: Subjects were treated as Jitai tablet alone, Jitai tablet plus buprenorphine and placebo, in a randomized,double-blind, placebo-controlled trial. Before and after the 14(th) day of withdrawal, levels of immunoglobulin (IgM, IgA, IgG), T cell subsets (CD(3)(+), CD(4)(+), CD(8)(+), CD(4)(+)/CD(8)(+)) and cytokines (IL-2, IFN-γ, IL-4, IFN-γ/IL-4) were detected. Results: Compared with healthy people, immunity function before withdrawal among the opioid abusers showed higher levels of IgM, IL-2, IFN-γ, IL-4 and lower level of CD(3)(+)T, as (1.67±0.87) g/L, (14.44±13.50)%, (20.23±15.10)%, (1.97±1.59)%, (47.01±13.62)%, respectively, with difference statistically significant (P<0.05). There was no big difference of other immunity indicators between the two groups (P>0.05). At the 14(th) day of withdrawal in placebo group, levels of IL-4 returned to normal while IFN-γ/IL-4 ratio increased by 3.43 times (P<0.05). Levels of IgA, IgG, CD(4)(+) and CD(4)(+)/CD(8)(+) ratio fluctuated within normal range. There were no significant changes in other immunity indicators (P>0.05). Compared with placebo group, fluctuation of IgG and IgM decreased in Jitai group during withdrawal period, together with a normal level of IgM at the 14(th) day. Level of IL-4 abnormally rose up by 0.54 times in Jitai tablet plus buprenorphine group, while IFN-γ/IL-4 ratio been switched back at the 14(th) day of withdrawal. Other immune indicators were not affected by medical interventions. Conclusion: We noticed that certain impairment of the immune function might be restored by Jitai tablet during the withdrawal period.

Abstract
Objective: To evaluate the safety of Tanreqing injection among children in the real world. Methods: A multicenter, large sample, ambispective cohort study, with registration-type clinical safety monitoring. A total of 6 188 inpatients and patients from the emergency units, aged ≤ 14 years who all had been using Tanreqing injection in 59 secondary and tertiary hospitals in China, were recruited between January, 2014 and May, 2015. The main outcomes would include incidence and severity of adverse drug reaction (ADR)/adverse drug event (ADE) of Tanreqing injection. Univariate analysis was used to explain the risk factors of ADR. Results: The overall incidence of ADE was 4.20‰ (26 cases), including 4 serious ones. The incidence of ADR was 3.07‰ (19 cases), including 17 cases of general ADR and 2 cases of new ADR. All the ADR cases were mild or moderate, mostly showing damages in skin and appendages. The onset of disease happened in 24 hours after the Tanreqing injection but all the ADR cases got improved or cured. Having histories of allergies to drugs or foods would increase the incidence of ADR. Conclusion:Tanreqing injection caused low incidence of ADR in children. Progams as stratifying high-risk patients and improving administrative management could further increase the safety level of Tanreqing injection.
