Pregnant women with subacute thyroiditis (SAT) are rare.One case was reported and the clinical features and management principles of SAT during pregnancy were reviewed.In pregnant women with SAT,the illness is usually not serious.If subclinical or clinical hypothyroidism develops,L-T4 must be given and thyroid function be monitored routinely,and the medication be adjusted carefully to ensure the maternal-fetal safety.

Objective To investigate the genotypes of β-lactamases produced by Klebsiella pneumoniae.Methods Plasmid conjugation,PCR amplification,gene cloning and DNA sequencing,isoelectric focusing electrophoresis and extended-spectrum β-lactamase(ESBLs)confirmatory test were carried out for analyzing the encoding gene of β-lactamases in clinical strains of Klebsiella pneumoniae collected from hospital wards.Results Totally 75 clinical strains of Klebsiella pneumoniae were collected,in which 48 strains were confirmed to produce genotype of β-laetamases(64.0%),including 39 ESBLs-producing Btraim(52.0%).Among 48 strains,17 isolates(35.4%)carried 2 types of ESBLs genes,7(14.6%)carried 3 types of ESBL8 genes,and 5(10.4%)carried 4 types of ESBLs genes.CTX-M was the most comon type(30/48,62.5%),followed by TEM(26/48,54.2%)and SHV(25/48,52.1%).Among 9 isolates with DHA-1 AmpC β-laetamase,8 produced AmpC β-lactamases and ESBLs.Class A carbapenemase KPC-2 was produced in 3 isolates.False negative rate of ESBLs confirmatory test was 23.1%(9/39).Condusion Genotypes of β-lactamases produced by Klebsiella pneumoniae are complicated,which results in multi-drug resistance in clinic.

OBJECTIVE: Complication incidence of urinary fistula which frequently occurs following renal transplantation is 3%-10%. Thus, poor processing may cause loss of transplanted kidney. This study was designed to retrospectively analyze urinary fistula following renal transplantation and to summarize the processing experience. METHODS: A total of 27 out of 1 203 patients with urinary fistula following renal transplantation (16 males and female 11 and mean age of 43 years) were collected from Guangzhou General Hospital of Guangzhou Military Command of Chinese PLA from December 2000 to March 2009. Totally, 26 patients accepted donor kidney from corpse, and 1 from living body. All patients were treated with expectant treatment (n=17) including inserting 18Fr Foley catheter alone and draining from the native drainage channel of operative site (n=12) and inserting a ureteral stent (single-J) by cystoscope retrograde approach and inserting 18Fr Foley catheter into the bladder (n=5); exploring operation (n=10) including anastomosing ureter and bladder and placing ureteral stent (n=5) and anastomosing ureter and ureter of recipient and placing ureteral stent (n=5); pedicled omentum grafts to cover and surround stoma after suturing (n=6). RESULTS: Only 1 case was failed because kidney vain was injured in the second operation and the kidney was resected. Another 26 cases were cured. Within the 3 month to 7 years follow-up, the urinary fistulas did not relapse, no stegnosis or hydronephrosis, no urinary tract infection and renal function were normal. CONCLUSION: Rapid diagnosis and treatment for urinary fistulas after renal transplantation is imperative. First mostly patients may be cured by expectant treatment. If not then perform exploratory operation. Using peclicled omentum grafts to cover and surround stoma after suturing for complex urinary fistulas can raise achievement ratio of operation.

Objective To compare zinc-finger BED domain-containing 3 ( ZBED3 ) expression in various tissues of C57BL/6J mice and the effects of liraglutide, glucose, and insulin on the levels of ZBED3 protein expression in C57BL/6J mice and db/db mice. Methods The mRNA level of ZBED3 in various tissues of C57BL/6J mice was measured by realtime PCR. The protein level of ZBED3 was measured by using western blot. Results ZBED3 mRNA levels were detected in muscle, spleen, kidney, brain, heart, lung, and liver of C57BL/6J mice, yielding the highest expression in muscle. Additionally, The liver ZBED3 levels were higher in db/db mice compared with C57BL/6J mice (P<0. 01). Furthermore, the protein expression of ZBED3 was significantly increased in liver tissues of db/db mice treated with high concentrations of liraglutide, glucose or insulin(P<0. 05), however, the expression of ZBED3 only responded to high concentration of glucose in liver tissues of C57BL/6J mice. Conclusion ZBED3 may act as a novel factor in regulating glucose metabolism. The expression of ZBED3 can be regulated by liraglutide, glucose, and insulin. Thus, ZBED3 may play an important role in conditioning of hyperglycemia.

ObjectiveTo discuss the incidence,treatment and effect of cryptogenic hemoptysis (CH).MethodsPatients with CH were selected from 231 patients with hemoptysis according to clinical evaluation,chest radiography,fiberoptic bronchoscopy and CT scan,and the clinical data and treatment methods were retrospectively analyzed.ResultsFifty-three of 231 patients referred for CH,the incidence of CH was 22.94 ％ (53/231),of which 45 (45/53,84.91％ ) received internal conservative treatment and 8 (8/53,15.09％) received bronchial artery embolization (BAE).High resolution CT (HRCT) showed ground-glass opacities in 20 CH patients after hemoptysis.Bronchial arteriography showed abnormalities,including arterial enlargement and localized hypervascularity in 8 patients and systemic to pulmonary shunting in 3 patients.No recurrence of hemoptysis was observed during 1 to 8-year follow-up.ConclusionBleeding can be controlled in most of CH patients by internal conservative treatment,only a few patients with massive hemoptysis need BAE,and both treatments have good short and long term results.

OBJECTIVETo demonstrate the effectiveness of prevention of mother-to-child HIV, syphilis, and hepatitis B transmission among pregnant women in Dehong prefecture, Yunnan province, China from 2011 to 2013.

From 2011 to 2013, the HIV positive rates were 0.87% (327/37 787),0.82% (319/38 817) and 0.85% (315/37 261), the syphilis positive rates were 0.05% (10/18 520),0.12% (43/36 817) and 0.11% (40/35 888), the hepatitis B positive rates were 2.46% (456/18 520), 2.23% (794/35 547) and 2.14% (739/34 468), respectively. The rates of HIV-positive pregnant women giving birth in hospitals were 99.2% (128/129), 100.0% (141/141) and 100.0% (141/141). From 2011 to 2013, the proportions of HIV-positive pregnant women receiving antiretroviral therapy were 99.2% (128/129), 99.3% (140/141) and 99.3% (140/141), respectively. And the treatment rate of syphilis-positive pregnant women were 71% (5/7), 89% (16/18) and 97% (32/33). The rates of hepatitis B immunoglobulin injection among new-borns of hepatitis B-positive pregnant women were 92.9% (263/283), 99.7% (612/614) and 99.4% (629/633). The estimated rates of mother-to-child transmission of HIV were 2.28%, 2.30% and 3.00%, respectively.

CONCLUSIONThere was an increasing trend of HIV, syphilis, and hepatitis B testing rate and the positive rate kept at a low level. The proportions of HIV-positive pregnant women receiving HIV, syphilis, and hepatitis B PMTCT services increased annually, while the proportion of HIV MTCT kept at an overall low level from 2011 to 2013, which indicated its effectiveness of HIV PMTCT work during recent years in Dehong prefecture,Yunnan province, China.

OBJECTIVETo conduct health economic evaluation of the prevention of mother-to-child HIV among pregnant women in Dehong prefecture, Yunnan province, China from 2004 to 2013.

METHODSData on cost were collected mainly from the annual prevention of mother-to-child transmission (PMTCT) reporting system of Dehong prefecture, and supplemented by HIV PMTCT-related resource allocation data from local health bureau. Effectiveness indexes were from local continuous HIV surveillance system and annual reported data. Cost-effectiveness and cost-utility analysis were used to conduct the health economic evaluation.

RESULTSFrom 2004 to 2013, 283980 pregnant women were screened for HIV, 2 059 were detected as positive, and the HIV positive rate was 0.73%. The total cost of the PMTCT program was 14 227 000 RMB after discounting, and the unit cost of positive case finding was 4 200 RMB. A total of 26 cases of adults and 325 infants were avoided HIV infection, and the cost-effectiveness ratio (CER) was 40 500 RMB/case. The total obtained quality adjusted life years (QALY) from the program was 8 911.5, each one of which cost 1 600 RMB/QALY. If the feeding pattern were breast feeding, CER would be 42 800 RMB/case and each one of QALY would cost 2 200 RMB.

CONCLUSIONBased on the cost-effectiveness and cost-utility analysis, the HIV PMTCT of Dehong prefecture had economic value, which indicates that continued investment is needed to strengthen local HIV PMTCT work.

Objective Toinvestigateantimicrobialresistanceamonggram-positivecocciinChinain 2013.Methods Retrospectivestudy.FromJune2013toDecember2013,1663consecutiveandnon-repetitive gram-positive cocci were collected from 15 teaching hospitals. The minimal inhibitory concentration ( MIC) of antibacterial agents was determined by agar dilution method. A retrospective study was conducted on rates of resistance to antimicrobial agents. The prevalence of penicillin-resistant Streptococcus pneumoniae ( PRSP) between children and adult patients and the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) between elder group and younger adult patients were compared using chi-square test. Results The prevalence of PRSP in children below 3 years old ( 72. 9%, 51/70 ) was higher than adult patients (55. 2%, 106/192) (χ2 =6. 653,P<0. 05). About 94. 9%(261/275) and (92. 7%,255/275) of S. pneumonia were resistant to erythromycin and clindamycin. All S. pneumoniae strains were susceptible to teicoplanin, vancomycin, linezolid, tigecycline and daptomycin. Penicillin still showed very high activity against Streptococcus spp. β-Hemolytic group. More than 60% of Streptococcus spp.β-Hemolytic group were resistant to erythromycin, clindamycin and tetracyclines. The prevalence of MRSA and methicillin-resistant coagulase-negative Staphylococci(MRCoNS) was 39. 7%(229/576) and 80. 6%(224/278), respectively. The MRSA prevalence ranged from 24. 2% to 70. 0% in different regions. About 52. 6%( 100/190 ) of Staphylococcus aureus from respiratory tract specimens, 38. 5%(40/104)of Staphylococcus aureus from blood samples, and 29. 7%(58/195) of Staphylococcus aureus from wound and pus were resistant to methicillin. The prevalence of MRSA in elder group ( 48. 6%, 84/173 ) was higher than that in younger adult patients (35. 7%, 144/403)(χ2 =8. 322,P <0. 05). The susceptibility rates of MRSA to chloramphenicol and trimethoprim/sulfamethoxazole were 86. 4% ( 244/228 ) and 94. 7% ( 237/228 ) , respectively. Susceptibility rates to gentamycin, erythromycin, clindamycin, tetracyclines, rifampicin and quinolones were ranged from 15. 8% to 59. 6%. All Staphylococci isolates were susceptible to teicoplanin, vancomycin, linezolid, daptomycin and tigecycline. All Enterococcus isolates were susceptible to daptomycin and tigecycline. All E. faecalis ( 158/158 ) and 96. 4% ( 133/138 ) of E. faecium were susceptible to teicoplanin. About 98. 0% ( 150/153 ) of E. faecalis and 97. 1% ( 145/138 ) of E. faecium were susceptible to linezoild. About 45. 8% (70/153) of E. faecalis and 60. 9% (84/138) of E. faecium were resistant to gentamycin with a high concentration. The susceptibility of E. faecalis to all the antibiotics tested exceptchloramphenicolandtetracyclinewashigherthanthatofE.faecium.Conclusions Basedon different age groups and regions, the resistance rates of Gram-positive cocci are different. Teicoplanin, vancomycin, tigecycline, daptomycin, linezolid and tedizolid showed very high activity against Gram-positive cocci. (Chin J Lab Med,2015,38:373-381)

Objective To investigate antimicrobial resistance among gram-positive cocci in 14 teaching hospitals in China in 2011.Methods From June 2011 to December 2011,1498 consecutive and non-repetitive gram-positive cocci were collected from 14 teaching hospitals.The minimal inhibitory concentration (MIC) of antibacterial agents was determined by agar dilution method.A retrospective study was conducted on rates of resistance to antimicrobial agents.Data was compared using chi-square test.Results The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and methicillinresistant coagulase-negative Staphylococci (MRCoNS) was 43.7％ (222/508),and 85.6％ (214/250),respectively.The MRSA prevalence ranged from 20.0％ to 63.5％ in different regions.About 58.2％ (82/141) of Staphylococcus aureus from respiratory tract specimens,44.8％ (48/107) of Staphylococcus aureus from blood samples,and 23.8％ (31/130) of Staphylococcus aureus from pus and wound were resistant to methicillin.The susceptible rates of MRSA to chloramphenicol and sulfamethoxazole-trimethoprim SXT were 94.1％ (209/222) and 83.3％ (185/222),respectively.Susceptibility to gentamycin,erythromycin,clindamycin,tetracyclines,rifampicin and quinolones were from 11.3％ to 52.3％.All Staphylococci isolates were susceptible to vancomycin,teicoplanin,linezolid and daptomycin.Five vancomycin-resistant enterococcus (VRE) strains were found in this study.All enterococcus isolates were susceptible to daptomycin(268/268),and 98.3％ (118/120) of E.faecalis and 99.3％ (147/148) of E.faecium were susceptible to linezoild.About 45.9％ (68/148) of E.faecalis and 67.5％ (81/120) of E.faecium were resistant to high concentration gentamycin.The susceptibility of E.faecalis to all the antibiotics except for chloramphenicol and tetracycline was higher than that of E.faecium.The prevalence of penicillinnonsusceptible Streptococcus pneumoniae (PNSSP) was 15.5％ (37/239).The prevalence of PNSSP in children below 3 years-old was 25％ (13/52),and the prevalence of PNSSP from other patients was 13％(24/187).About 91.6％ (219/239),88.7％ (212/239) and 88.3％ (211/239) of S.pneumonia was resistant to erythromycin,clindamycin and tetracyclines.All S.pneumoniae strains were susceptible to teicoplanin,vancomycin,linezolid,tigecycline and daptomycin.Penicillin still showed high activity against Streptococcus spp.β-hemolytic group.More than 60％ of Streptococcus.spp.β-hemolytic group are resistant to erythromycin,clindamycin and tetracyclines.Conclusions Based on regions,the resistance rates of Gram-positive cocci are different,of which,the increasing tendency should be taken seriously.Teicoplanin,vancomycin,linezolid,tigecycline and daptomycin show very high activity against Gram-positive cocci.

Objective:To investigate the efficiency and safety of traditional growing rod in the treatment of early onset dystrophic scoliosis secondary to type 1 neurofibromatosis (NF1-DS) with intraspinal rib head in children.Methods:From September 2006 to May 2020, this study recruited 20 children with intraspinal rib head with early onset NF1-DS who had received traditional growing rods. There were 13 boys and 7 girls and the age of the initial operation was 7.0±1.6 years (range, 4.1-9.8 years). There were 7 cases of simple left chest bend, 9 cases of simple right chest bend, and 4 cases of double chest bend; 13 patients had varying degrees of kyphosis deformity. Two children had neurological symptoms before surgery, American Spinal Injury Association Impairment Scale (AIS) were grade D. The proportion of the intraspinal rib head (IRP), the Cobb angle of the main chest bend, apical vertebra rotation (AVR), apical vertebral translation (AVT), trunk shift (TS) and sagittal TK, lumbar lordosis (LL), sagittal balance and T 1-S 1 height were measured before and after first time internal fixation and at last follow-up, and the complications were also evaluated. Results:All 20 patients were followed up and the average follow-up time was 41.6±23.8 months (range, 24-99 months). A total of 85 operations was conducted including 63 protrude operations. After operation, the IRP was significantly lower than that before operation (preoperative 33.1%±17.5% vs. postoperative 22.2%±11.3%, P<0.001) and no significant correction loss was found at last follow-up 23.7%±12.4% ( P>0.05). The mean Cobb angle decreased from 75.9°±26.7° preoperatively to 45.0°±18.5° postoperatively ( P<0.001) and there was still significant improvement at the last follow-up (41.0°±17.2°) compared with postoperatively ( P<0.05). The AVR was significantly reduced after surgery compared with preoperatively (33.0°±10.1° vs. 39.3°±13.3°, P<0.001), and the last follow-up (40.1°±11.4°) was significantly improved compared with postoperative ( P=0.005). The T 1-S 1 height increased from 259.8±70.7 mm preoperatively to 296.9±78.4 mm postoperatively ( P=0.001), and at the last follow-up 296.9±78.4 mm was still significantly higher than after operation ( P<0.001), with an average annual increase of 12.4±3.2 mm. Significant correction of AVT, TK, LL and sagittal balance were noted after initial surgery ( P<0.05), and no significant correction loss was found at last follow-up ( P>0.05). There were 10 complications in 7 cases. There were 5 complications of pedicle screw loosening, 1 complication of bolt droping, 2 complications of broken rod, 1 complication of distal junctional kyphosis and 1 complication of adding-on phenomenon. 2 cases with nerve injury were recover after operation (AIS grading E). None of the children had new neurological complications during growth rod insertion and multiple stretching during follow-up. Conclusion:For children with early onset NF1-DS with intraspinal rib head, if the preoperative AIS grade is D or E, traditional growing rod technique is relatively safe and effective and can make the intraspinal rib head remove from the spinal canal partly.
