Objective To investigate DNA methylation markers in the whole blood of patients with systemic lupus erythematosus(SLE),in hope to facilitate the evaluation of SLE severity.Methods Whole blood samples were obtained from 58 patients with SLE(including 14 cases of severe SLE,25 moderate SLE,19 inactive SLE)and 50 healthy controls.Bisulphite sequencing was performed to determine the methylation status of interleukin-2 common receptor gamma chain(IL-2RG)promoter region,and real-time reverse transcriptionPCR to quantify the expression level of IL-2RG mRNA,in these subjects.Results The methylation level of IL2RG promoter region was 0.217 ± 0.140,0.325 ± 0.230,0.342 ± 0.085 and 0.175 ± 0.036 in the patients withsevere,moderate and inactive SLE and healthy controls,respectively.A significant increase was observed in the methylation level of IL-2RG promoter region in the patients with inactive SLE compared with the patients with severe SLE and healthy controls(both P ＜ 0.01),and in the patients with SLE compared with the healthy controls(0.263 ± 0.047 vs.0.175 ± 0.036,P ＜ 0.05).The expression level of IL-2RG mRNA was significantly lower in the patients with SLE than in the healthy controls(2.550 ± 0.823 vs.4.293 ± 1.283,P ＜ 0.05).A negative correlation was observed between the expression level of IL-2RG mRNA and methylation level of IL2RG promoter region in 20 patients with SLE(r =-0.44,P ＜ 0.05).Conclusion The methylation status of IL2RG promoter region is statistically higher in patients with SLE than in healthy controls,and significantly different between patients with active SLE and those with stable SLE.

OBJECTIVETo study the causes of orchiectomy in different age groups.

METHODSWe retrospectively reviewed the clinical data about 291 cases of orchiectomy performed between March 1993 and October 2014 and analyzed the causes of surgery and their distribution in different age groups.

RESULTSThe main causes of orchiectomy were testicular torsion (45.8%), cryptorchidism (32.5%) and testicular tumor (16.9%) in the patients aged 0-25 years, testicular tumor (42.4%), cryptorchidism (25.9%) and tuberculosis (10.6%) in those aged 26-50 years. Prostate cancer was the leading cause in those aged 51-75 years (77.6%) or older (84.0%)), and testicular tumor was another cause in the 51-75 years old men (10.2%). Prostate cancer, testicular tumor, cryptorchidism, and testicular torsion were the first four causes of orchiectomy between 1993 and 2009. From 2010 to 2014, however, testicular tumor rose to the top while prostate cancer dropped to the fourth place.

CONCLUSIONThe causes of orchiectomy vary in different age groups. The proportion of castration for prostate cancer patients significantly reduced in the past five years, which might be attributed to the improvement of comprehensive health care service.

Objective:To investigate the diagnostic performance of Xpert Mycobacterium tuberculosis/rifampin (Xpert MTB/RIF) assay for pulmonary tuberculosis (TB) in patients with acquired immunodeficiency syndrome (AIDS). Methods:Clinical data of 226 patients with AIDS and suspected pulmonary TB in Shanghai Public Health Clinical Center, Fudan University from July 2017 to November 2019 were retrospectively analyzed. Fluorescence staining microscopy of sputum smear, BACTEC MGIT 960 liquid culture (or Roche solid culture) and Xpert MTB/RIF assay were implemented respectively. The sensitivity and specificity of Xpert MTB/RIF in the diagnosis of Mycobacterium tuberculosis (MTB) infection and rifampin resistance were analyzed. Results:Totally 226 patients of suspected pulmonary TB were enrolled. There were 94(41.6%) patients had positive mycobacterium culture, in which 51 (54.3%) were MTB and 43 (45.7%) were nontuberculous mycobacteria (NTM). Using the positive MTB culture of sputum and mycobacterial protein from BCG of Rm 0.64 in electrophoresis (MPB64) as reference standard, the sensitivity and specificity of Xpert MTB/RIF assay for MTB diagnosis were 72.6%(95% confidence interval ( CI) 66.7%-78.4%) and 97.1% (95% CI 95.0%-99.3%), respectively. The sensitivity and specificity of Xpert MTB/RIF assay for MTB diagnosis in patients with positive sputum smear were 76.7%(95% CI 67.7%-85.8%) and 90.0(95% CI 83.6%-96.5%), respectively. The sensitivity and specificity of Xpert MTB/RIF assay for MTB diagnosis in patients with negative sputum smear were 50.0%(95% CI 41.8%-58.2%)and 99.3%(95% CI 97.9%-100.0%), respectively. With phenotypic resistance as reference standard, the sensitivity and specificity of Xpert MTB/RIF assay for rifampicin resistance were 75.0% and 100.0%, respectively. Conclusion:Among AIDS patients, the performance of Xpert MTB/RIF assay for pulmonary TB diagnosis is pretty good and could differentiate MTB from NTM rapidly, which has good application value.

Abstract: To explore the clinical characteristics, diagnosis and treatment of imported severe malaria and COVID-19 co-infection cases, and to provide scientific basis for epidemic prevention and control measures. The epidemiological characteristics, clinical manifestations, laboratory tests, treatment process and prognosis of 4 cases of severe malaria and COVID-19 co-infection with confirmed diagnosis were analyzed retrospectively. Four cases of severe malaria were African returnees of the same batch, male, aged 40-54 years old, with the same journey track. They all had African work and life history and acute onset. The main clinical manifestations were fever (4/4), chills (3/4), chills (3/4), nausea and vomiting (3/4), diarrhea (4/4), fatigue and anorexia (4/4). Two cases had headache and dizziness, confusion, muscle aches, two cases had cough, one cases had sputum, sore throat and runny urine. All 4 cases were confirmed by positive nucleic acid detection of the new coronavirus (2019-nCOV) in throat swabs. Plasmodium falciparum was found by microscopic examination of peripheral blood smears of all patients, and all of them were consistent with high altitude helminthiasis. All cases were accompanied by abnormal liver function and severe hypoproteinemia, two cases were hyperbilirubinemia, three cases were dyslipidemia, three cases were involved in abnormal tertiary hemogram with different degrees of elevation of procalcitonin, two cases were lactic acid poisoning, and one case was hypoglycemia. One case showed viral pneumonia on chest CT. All cases were treated individually according to the different conditions and were discharged after improvement, and were rechecked for 2019-nCOV nucleic acid and microscopic examination of blood smear negative for Plasmodium.During the global COVID-19 epidemic, the emergence of coinfection cases of con-infection of imported malaria parasites and severe acuterespiratory syndrome coronavirus 2 (SARS-CoV-2) makes the clinical diagnosis and treatment more complicated. It is important to establish the awareness of simultaneous prevention and diagnosis of COVID-19 and malaria for local prevention and control and early warning of severe cases, and timely and effective formulation of treatment plan to improve the comprehensive treatment efficiency.

To research the effect of Ginseng Radix et Rhizoma and Aconiti Lateralis Radix Praeparata compatibility on cardiac toxicity in rats by UPLC-Q-TOF/MS, and explore the endogenous markers and molecule mechanism. Different compatibility of Shenfu decoction were given to male Wistar rats at dosage of 20 g · kg(-1) for 7 days, collected the serum, and analyze the endogenous metabolites effected by Shenfu formulation by principal component analysis and partial least-squares analysis. Results showed that content of glutathione, phosphatidylcholine and citric acid decreased in mixed-decoction group, while ascorbic acid, uric acid, D-galactose, tryptophan, L-phenylalanine increased. The results showed cardiac toxicity of Aconiti Lateralis Radix Praeparata in Shenfu mixed-decoction. Shenfu co-decoction group showed a similar or weaker trend compared with control group, but most of them do not have a statistically significant. The results indicated the scientific basis of Shenfu compatibility by comparison of co-decoction group with mixed-decoction group. Shenfu compatibility can reduce cardiac toxicity induced by Aconiti Lateralis Radix Praeparata, and citric acid, glutathione, phosphatidyl choline, uric acid might be regarded as potential markers of cardiotoxicity.

OBJECTIVETo study the effects of ApoE gene polymorphism on anti-inflammatory action of Xuezhikang Capsule.

METHODSOne hundred and two patients with hyperlipidemia (as the treated group) and one hundred healthy volunteers (as the control group) were enrolled in the case-control study. Total DNA of the peripheral blood was extracted and ApoE genotypes were determined by PCR sequence analysis. The serum levels of tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), and high sensitivity C reactive protein (hs-CRP)were measured in all subjects. The changes of TNF-alpha, IL-6, and hs-CRP were detected before and after 6-week Xuezhikang Capsule treatment, thus analyzing the correlation between ApoE gene polymorphism and changes of each inflammatory factor.

RESULTSThe frequency of E3/3 genotype was 86% (86/100 cases)in the control group, significantly higher than that of the treated group (62.7%, 64/102 cases). The frequency of E3/4 genotype was 6% (6/100 cases) in the control group, significantly lower than that of the treated group (21.6%, 22/102 cases; both P < 0.05). Compared with the control group, the serum levels of TNF-alpha, IL-6, and hs-CPR were higher in the treated group before treatment (P < 0.05). In hyperlipidemia patients with E3/4 + E4/4 genotype, the serum level of TNF-alpha was higher than that of E3/3 genotype (P < 0.05); the serum level of IL-6 was higher than that of E2/E2 + E2/E3 genotype (P < 0.05); the serum level of hs-CRP was higher than that of E2/E2 + E2/E3 and E3/E3 genotype (P < 0.05). But there was no statistical difference in the serum levels of TNF-alpha, IL-6, or hs-CPR between E3/3 and E2/E2 + E2/E3 genotype. After 6-week intervention of Xuezhikang Capsule, the serum levels of TNF-alpha, IL-6, and hs-CRP were lower in the treated group (P < 0.05), but the serum levels of TNF-alpha and IL-6 were still higher than those of the control group (P < 0.05). But there was no statistical difference in the decrement of TNF-alpha, IL-6, or hsCRP among E2/E2 + E2/E3, E3/E3, or E3/4 + E4/4 genotypes (P > 0.05).

CONCLUSIONSThe distribution of ApoE gene polymorphism is different between the hyperlipidemia patients and the healthy people. Chronic inflammatory reactions exist in hyperlipidemia patients, especially in those with e4 allele. Xuezhikang Capsule showed anti-inflammatory effects, but ApoE gene polymorphism did not affect its effects.

OBJECTIVESTo investigate role of hypoxia inducible factor 1 (HIF-1) in the transcriptional activation of heat shock protein 70-2 (HSP70-2) in hepatocellular carcinoma (HCC) cells under hypoxic conditions.

METHODSHCC cells were exposed to reduced oxygen atmosphere (1% O2), or treated with YC-1 or HIF-1 alpha siRNA, the expression of HIF-1 alpha and HSP70-2 were detected by Western blot analysis. Serial deletions of the HSPA2 promoter were cloned in the reporter pGL3-Basic plasmid. These reporter plasmids were co-transfected with HIF-1 alpha siRNA, and the promoter activities were detected with the dual luciferase assay.

RESULTSWestern blot analysis showed that both HIF-1 alpha and HSP70-2 proteins were strongly increased after HCC cells were exposed to hypoxic conditions (1% O2) for 6 h, and the expression level of HSP70-2 was increased in a time-dependent manner. Treatment of HepG2 cells with YC-1 or HIF-1 alpha siRNA significantly inhibited the expression of HIF-1 alpha and HSP70-2. In silico analysis of the HSP70-2 promoter using the Gene2 Promoter software revealed the presence of two putative hypoxic response element (HRE) consensus at -446bp (HRE1) and -238bp (HRE2). Depletion of promoter sequence between -653 and -385 led to a dramatic reduction of promoter activity, whereas further deletion to position -201 did not reduce the activity further. These data suggested that HRE1 plays an important role in hypoxia-induced activation of the HSPA2 promoter. Site-directed mutagenesis further confirmed these results. Mutation of HRE1 but not of HRE2 abrogated the sensitivity of the HSP70-2 promoter to hypoxia.

CONCLUSIONSHSP70-2 expression is up-regulated in response to hypoxia and a HIF-1 binding site (HRE1) in the HSP70-2 promoter is involved in this response.

OBJECTIVETo investigate the techniques and therapeutic effects of suture anchors for the reconstruction of distal tendo achillis rupture.

METHODSThe clinical data of 16 patients of distal tendo achillis rupture repaired with suture anchors from June 2005 to August 2008 were retrospectively analyzed. Among them, there were 13 males and 3 females with a mean age of 33.5 years (ranged from 17 to 46 years). The postoperative rehabilitation was conducted for every patient. The operation time, position of suture anchor and complications of the surgery were analyzed. The healing of stendo achillis and functional recovery were assessed by Arner-Lindholm standard.

RESULTSAll the patients were followed up for an average of 13.2 months. There were no complications of foreign-body reaction or re-rupture. The average operation time was 35.5 minute. There was no intraoperative injuries of blood vessels, nerves or tendons. A total of 19 suture anchors were used, and only 1 anchor was displaced. The functional recovery of tendo achillis was rated as excellent in 13 cases,good in 2 cases, bad in 1 case. All patients were satisfied with the effects on their current work and life. And no displacement of anchors was found in radiographic films.

CONCLUSIONRepairing of the distal tendo achillis rupture with suture anchors can make operation simple and quick, rigid fixation, less complications, and provide good therapeutic effects.
