Abstract： Objective　To analyze the changes of cytokine levels in patients with sensitive pulmonary tuberculosis and drug-resistant pulmonary tuberculosis before and after anti-tuberculosis treatment. Methods　The clinical data of 213 pulmonary tuberculosis patients admitted to the Eighth Affiliated Hospital of Xinjiang Medical University from August 2019 to October 2020 were collected, and divided into a sensitive pulmonary tuberculosis group and a drug-resistant pulmonary tuberculosis group, of which 141 were in the sensitive group and 72 in the drug-resistant group , and the pro-inflammatory factors tumor necrosis factor-α (TNF-α), IL-6, IL-17, interferon-γ (IFN-γ) and anti-inflammatory factors IL-10 and IL-4 in plasma before treatment, 3 months and 6 months after treatment were compared. Results　Compared with the healthy group, the levels of plasma IL-6 in the sensitive group and the resistant group were significantly increased, difference was statistically significant (P<0.01). The plasma levels of IFN-γ and IL-17 in the sensitive group were increased, and the difference was statistically significant (P<0.05). Compared with before treatment, the levels of IL-6 and IL-4 in the plasma of the sensitive group after 6 months of treatment were lower than those after 3 months of treatment, and the difference was statistically significant (P<0.05), and IFN-γ was significantly decreased (P<0.001). After 6 months of treatment, the IL-10 content was lower than that before treatment, and the difference was statistically significant (P<0.05), and the IFN-γ decreased significantly (P<0.000 1). The levels of IFN-γ at 3 months were higher than those in the resistant group, and the difference was statistically significant (P<0.01). After 6 months of treatment, there was no significant difference in the content of IFN-γ between the sensitive group and the resistant group. The effective rate of CT absorption was 70% in the sensitive group and only 43.33% in the resistant group at 3 months of treatment, and there was no significant difference in the effective rate between the two groups after 6 months of treatment. Conclusions　Detection of pro-inflammatory cytokines and anti-inflammatory cytokines in plasma can provide reference for host-directed therapy of pulmonary tuberculosis. Understanding this important feature of cytokines on pathogen-host interactions can provide new insights into the study of virulence mechanisms and may provide new approaches for immune intervention in pulmonary tuberculosis.

Objective To explore the change of activin A(ACT A) in umbilical artery blood of newborns with fetal distress and its clinical significance.Methods Forty healthy pregnant women(control group)and 35 pregnant women with fetal distress (experimental group)were collected.The levels of ACT A of umbilical artery blood in both groups were determined by a solid quantitative biotin-avidin system enzyme-linked immunosorbent assay(BAS-ELISA),umbilical artery blood gas were also measured.Results The level of ACT A of umbilical artery blood in fetal distress group was (1 235.89?178.78)ng/L,and that in control group was (627.28?75.24)ng/L,and the level of ACT A of umbilical artery blood in fetal distress group was significantly higher than that in control group(P

ObjectiveTo evaluate the efficacy about the different wearing manner with Milwaukee and Boston for the treatment of adolescent idiopathic scoliosis (AIS).MethodsRetrospectively summarization and analysis was performed in 85 adolescent patients with idiopathic scoliosis who were treated from February 2004 to March 2009.The skeletal growth of them had not completed.There were 57 cases who received brace treatment.In them,28 were treated with (CTLSO) Milwaukee brace,and the rest were treated with (TLSO) Boston brace and orthopedic gymnastics.The 30 cases wear regularly used for 21 to 23hours per day,and 27 cases could consist on wearing only 6 to 15 hours per day.The other 28 cases of 85AIS cases were only treated with orthopedic gymnastics instead of orthosis treatment.All patients were periodically observed with lateral side (X)-ray photograph at standing position and photograph,and Cobb angle and Risser sign were measured every 3 to 6 months.Since 2008 all adolescent idiopathic scoliosis patients treated with orthosis were requested to fill with simplified Chinese SRS-22.Results73 cases adolescent idiopathic scoliosis patients were followed up for 2 ～5 years [ mean(26.3 ± 33.7)months ].Milwaukee orthosis group showed the regular wearing group had 91.67 ％ ( 11/12) effective rate and the intermittent wearing group had 56.25％ (9/16) effective rate and the group without wearing orthosis only had 20％ (4/20)effective rate.The group regularly wearing Milwaukee brace had superior effect than the other two groups (P ＜ 0.05 ).Boston orthosis group showed the regular wearing group had 88.89％ (16/18) effective rate and the intermittent wearing group had 54.55％ (6/11 ) effective rate and the group without wearing brace with 25％ (2/8) effective rate.The group regularly wearing Boston brace had better effect than the other two groups ( P ＜ 0.05 ).Due to the different choice of AIS patients and orthosis,the effective rate of the Milwaukee and Boston orthosis was not compared.ConclusionsThe adolescent idiopathic scoliosis patients should insist on regularly wearing brace regardless of the Milwaukee or Boston orthosis ( this article suggest that the wearing time should not less than 21 ～ 23 h/d).The group regularly wearing with the Milwaukee or Boston orthosis had better effect than the intermittent group or the group without wearing brace.It's a good treatment for the AIS patients who have with the indication of orthosis treatment.

Objective To evaluate the performance of Cys C results among two detection system.Methods The particle-enhanced immunonephrometic assay was used in Dade Behring BNII. Immunoturbic assay was used in Hitachi 7170 to evaluate the JING' YUAN reagents.We compared the precison,linearity,interference,correlation,and calibrators agreement with Dade Behring BNII.Results The total CV of the samples that contain 0.6-5.0 mg/L was less than 10%.The Dade Behring and JING'YUAN method showed good linearity.Haemoglobin(10 g/L),Bilirubin(300 mg/L), Vitamin C(5 g/L)in the tested sample had no significant interference in the assay(interference 0.05) between JING' YUAN and Dade Behring reagents.Values were slightly lower than that from the Dade Behring BNII method,the mean bias was-0.16.The bias range was 1.1%-23% between JING'YUAN and Dade Behring for one sample.Conclusions The precision,linearity and interference test were suitable for routine Cys C measurement on automated biochemistry analyzer,but results has bias.

Objective To evaluate the value of serum creatinine(Scr),creatinine clearance (Ccr),MDRD equation 7(MDRD 7),~(99)Tc~m-DTPA renal dynamic imaging(gGFR)and cystatin C in screening changed glomerular filtration function in type 2 diabetic patients.Methods The ~(99)Tc~m-Diethylene Triamine Pentaacetic Acid(~(99)Tc~m-DTPA)plasma clearance(rGFR)obtained with the dual plasma sampling method was used as a reference with which Scr,Ccr,MDRD 7,gGFR and Cystatin C were compared.Results Sixty of type 2 diabetic patients were selected,including 35 male and 25 female.The average age was(62.4?11.7)years and the average diabetic history was(10.66?9.35)years.Scr,Ccr, MDRD 7,gGFR were all correlated significantly with rGFR.Correlation coefficients were 0.675 for Ccr, -0.588 for Cystatin C,-0.500 for Scr,O.428 for MDRD 7,0.367 for gGFR(P values all

OBJECTIVETo explore the electrocardiogram and 3-dimensional electroanatomic mapping features and radiofrequency catheter ablation efficacy of patients with premature ventricular contractions (PVCs ) originating from His bundle region.

METHODSBetween February 2009 and February 2011, 10 consecutive patients ( 4 male, aged from 19 to 59 years) who underwent ablation for frequent PVCs originating close to His bundle region in our department were included. Electroanatomic mapping of RVOT and ASC, ablation was performed with the 7F 4-mm-tip ablation catheter.

RESULTSAmong these 10 patients with PVCs originating from His bundle region, 6 originated from the RVOT, 1 from NCC and 3 from RCC. Eight patients showed LBBB morphology,1 patient with PVCs originated from RCC and 1 patient with PVCs originated from NCC showed RBBB morphology. At the successful ablation sites, local ventricular activation v wave was detected 22-52 (32.6 ± 10.2) ms earlier than the QRS wave in the surface electrocardiogram. The distance between target and His bundle was 5.0-8.4(7.0 ± 1.1)mm. Ablation was successful in all 10 patients without complications (PVCs < 500 beats/24 h post ablation).

CONCLUSIONPVCs originating near the His bundle have similar electrocardiographic and electrophysiological characteristics for PVSc originated from the RVOT or ASC. Because of the close anatomical relationship between RVOT and ASC, it is necessary to mapping both RVOT and ASC to accurately identify the site of PVCs origin and to guild successful ablation.

OBJECTIVETo determine whether autoantibodies against the cardiac G-protein-coupled beta 2- and alpha 1-adrenergic and AT1 receptors are related to patients with primary hypertension.

METHODSSynthetic peptides corresponding to amino acid sequences of the second extracellular loops of the beta 2- and alpha 1-adrenergic and AT1 receptors were respectively used as antigens to screen sera from patients with hypertensive heart diseases (n = 50) as well as simple hypertension (n = 40) and healthy blood donors (n = 40) using ELISA test.

RESULTSThe positive ratio of autoantibodies against beta 2 and alpha 1 and AT1 receptors in patients with hypertensive heart diseases were significantly higher than patients with simple hypertension and healthy donors. The geometric mean titers of autoantibodies against beta 2- and alpha 1-adrenergic and AT1 receptors had no difference between the patients with hypertensive heart diseases and the patients with simple hypertension, but the geometric mean titers of two groups were higher than healthy donors. In the patients with hypertensive heart diseases, 81.0% of the patients with autoantibodies against beta 2-adrenergic receptor had autoantibodies against alpha 1-adrenergic receptor and 76.2% had autoantibodies against AT1 receptors. The percent of the autoantibodies against three receptors in patients with hypertensive heart diseases were 52.4%.

CONCLUSIONSAutoantibodies against beta 2- and alpha 1-adrenergic and AT1 receptors play an important role in the pathophysiological changes of primary hypertension, and may participate myocardial and vessel remodeling.

OBJECTIVEMutations of the iduronate-2-sulfatase (IDS) gene is the ultimate cause of Hunter syndrome. Clarification of the nature of mutations will create a necessary premise for prenatal gene diagnosis. A mucopolysaccharidosis (MPS) type II patient and his parents from an ethnic minority in Yunnan province were studied to identify their possible mutation in IDS gene to establish the basis for prenatal gene diagnosis.

METHODSThe patient was a boy, 6 years and 10 months old. Urine glycosaminoglycans (GAGs) assay was used for preliminary diagnosis of the patient and his parents with the disease. The three related persons' DNA was extracted and the concentration and purity of the DNA were measured after the urine test results confirmed the diagnosis. Polymerase chain reaction-denaturing high performance liquid chromatography (PCR-DHPLC) analysis was performed to detect the position of the mutation around the hot spots of mutation in exon 9, 3, 8 of the IDS gene. DNA bidirectional direct sequencing was applied to analyze the mutation detected by PCR-DHPLC.

RESULTSThe results of GAGs test showed that in the child with MPS, dermatan sulfate (DS) was positive (+++), heparan sulfate (HS) (+++), chondroitin sulfate (CS) and keratan sulfate (KS) were negative (-); while in his parents none of DS, HS, CS and KS was positive. Abnormal peaks in exon 9 of IDS gene shown by PCR-DHPLC were found in the patient. His mother had heterozygotic peaks. A new frame-mutation (1343-TT) in exon 9 of IDS gene of this patient was confirmed by DNA sequencing. The position where mutation occurred was inside codon 407 (TTT), that means two "T" deleted at position 1343 base pair (1343-TT) in cDNA of the IDS gene, caused a new frame-mutation. It caused elongation of the amino acid chain to a terminal codon TGA at position 429. Thus the peptide chain was shortened from 550 to 428 amino acids. The patient is a hemizygote of the mutation and his mother is a heterozygote.

CONCLUSIONA new frame-mutation (1343-TT) on the IDS gene was identified in this study. The patient is a hemizygote and his mother is a heterozygote. The mutation (1343-TT) resulted in loss of 122 amino acids, which probably caused seriously decreased enzyme activity of IDS, and the authors speculate that this mutation may be the pathological basis of the disease. So, if the mother becomes pregnant again, a prenatal gene diagnostic test for the same mutation should be performed. Furthermore, PCR-DHPLC followed by DNA sequencing are effective methods for diagnosis, including prenatal diagnosis of MPS II.

Introduction: Bekam, an Islamic variant of cupping, is an ancient form of traditional medicine still practised today in Malaysia. There are published findings indicating that cupping benefits patients with low back pain, other musculoskeletal pain and even pain from cancer, herpes zoster and trigeminal neuralgia when pain is measured on an analogue scale. We proposed to investigate whether in addition to pain improvement on an analogue scale we could show if pain relief might be demonstrated in terms of reduction of analgesic use. Methods: We carried out a retrospective cross sectional study on subjects who had been for outpatient clinic treatment with chronic pain of at least one month and who completed at least two bekam therapy sessions. In addition to documenting a pain score before and after therapy we documented their analgesic consumption. Results: A total of 77 respondents, with overlapping symptoms of headache, backache and joint pains were included. The mean pain score before bekam therapy was 6.74±1.78, and was 2.66±1.64 after two sessions of therapy. Twenty eight respondents completed six sessions of bekam therapy and had a mean pain score of 2.25±1.32 after. Thirty-four patients consumed analgesic medication before starting bekam therapy and only twelve did so after. The consumption of analgesics was significantly lower after bekam therapy. Conclusions: Bekam therapy appears to help patients experience less pain and reduce the amount of analgesic medication they consume. Nevertheless only a randomised prospective study will eliminate the biases a retrospective study is encumbered with and we believe would be worth doing.
