The abnormal rates of T3-T5 serum creatinine, T2 - T5 serum sodium and T1 - T5 platelet in deterioration died group were significantly higher than those in improvement survival group, the serum creatinine: 22.06%(15/68) vs. 6.90% (6/87), 27.49% (19/68) vs. 8.05% (7/87) and 42.65% (29/68) vs. 10.34% (9/87), the serum sodium: 32.35% (22/68) vs. 13.79% (12/87), 39.71% (27/68) vs. 14.94% (13/87), 48.53% (33/68) vs. 12.64%(11/87) and 60.29%(41/68) vs. 11.49%(10/87), the platelet:45.59%(31/68) vs. 21.84%(19/87), 55.88% (38/68) vs. 24.14% (21/87), 54.41% (37/68) vs. 25.29% (22/87), 55.88% (38/68) vs. 21.84%(19/87) and 61.76% (42/68) vs. 20.69% (18/87), and there were statistical differences (P<0.05). Abnormal rate of platelet was highest in each time point. Conclusions In the course of pathological changes in deterioration and dead patients, the platelet is the first and most easily affected compare with serum sodium and serum creatinine; the platelet may be a sensitive marker for predicting clinical outcome in patients with liver failure.

Objective To explore the aesthetic results of medial upper Iip repair for skin and soft tissue defects using local flap.Methods According to the location and the size of upper lip defect,the modified rhomboid flap of 60 ° above the defect was designed to repair the wound in philtrum;the O-L flap along philtral column to vermilion border was designed to cover the wound close to the peak and lateral to philtral column.Results Twenty-one postoperative patients that underwent pigmented nevus removal (12 female,9 male;ages 16-33 years) had defects in philtrum for 10 cases and close to the peak and philtral column for 11 cases.The diameter of the defect ranged from 0.5 cm to 1.0 cm.All flaps survived primarily without any complications and follow-up was for 1 to 18 months with excellent outcomes in all cases.All patients were satisfied with contour and functions.No pigmented nevus recurrence occurred.Conclusions The flap designed according to the aesthetic principle could be used to repair medial upper lip defect of medium-sized,which not only obtains functional reconstruction,but also satisfies aesthetic results,with aesthetic subunits saved and scar concealed.

Objective To systematically review the efficacy of multiple doses and single dose of perioperative dexamethasone on pain and recovery after total knee arthroplasty(TKA).Methods PubMed,Embase,Cochrane Library,Web of Science,CNKI,WanFang Data,SinoMed and VIP databases were electronically searched to collect randomized controlled trials(RCTs)on multiple doses and single dose of dexamethasone during perioperative period of TKA from inception of the databases to January 4,2024.Two reviewers independently screened the literature,extracted data and assessed the risk of bias of the included studies.Meta-analysis was performed by using RevMan 5.4 software.Results A total of 6 studies involving 674 patients were included,336 patients in single dose dexamethasone group and 338 patients in multiple dose dexamethasone group.The results of Meta-analysis showed that compared with single dose of dexamethasone,multiple doses of perioperative dexamethasone could significantly decrease the pain scores at rest at 48 h after TKA(SMD=-0.68,95%CI-1.05 to-0.30,P﹤0.001),the pain scores with movement at postoperative 48 h(SMD=-0.86,95%CI-1.37 to-0.34,P=0.001),C-reactive protein(CRP)levels at postoperative 48 h(MD=-4.43,95%CI-6.70 to-2.16,P﹤0.001)and CRP levels at postoperative 72 h(MD=-3.60,95%CI-5.53 to-1.67,P﹤0.001).There was no statistically significant difference between the two groups regarding pain scores at rest at postoperative 24 h and 72 h,pain scores with movement at postoperative 24 h and 72 h,incidence of postoperative nausea and vomiting(PONV),CRP levels at postoperative 24 h,length of hospital stay,and incidence of adverse drug reactions(P>0.05).The results of 5 studies showed that multiple doses of dexamethasone did not increase the dosage or patient proportion of remedial analgesics.Conclusion Current evidence shows that compared with single dose of dexamethasone,multiple doses of perioperative dexamethasone can significantly reduce pain scores at postoperative 48 h,CRP levels at postoperative 48 and 72 h after TKA,but it does not significantly reduce the incidence of PONV,hospital stay,or increase the risk of adverse drug reactions.

Objective: To investigate the prevalence and resistance changes of carbapenem-resistant Enterobacteriaceae (CRE) strains isolated from children patients of Chinese Bacterial Resistance Surveillance Network (CHINET) from 2005 to 2017. Methods: Antimicrobial susceptibility testing was carried out by disk diffusion method (KB method) and automated systems. Results were analyzed according to the Clinical and Laboratory Standards Institute (CLSI) 2017 edition standards. Results: Among the 4 481 CRE clinical strains, the overall prevalence of CRE in children was 6.4%, including 8.8% in neonatal period, 7.3% in infancy, 3.8% in early childhood, 4.0% in preschool, 4.7% at school age and 7.4% of puberty. The CRE prevalence of citrobacter spp. remained stable in 2005-2017, whereas other bacteria showed an upward trend, which was higher than that of the adult group (P<0.01). Among the 4 481 CRE strains, there were 2 905 strains of Klebsiella spp. (64.8%), 813 strains of Escherichia coli (18.1%), 549 strains of Enterobacter spp.(12.3%), and 65 strains of Citrobacter spp.(1.5%). Among the 4 481 CRE strains, 20.7%, 13.3%, and 11.8% were from the intensive care unit (ICU), neonatal department and internal medicine wards, respectively. Specimens were distributed as respiratory (42.8%), urine (26.3%), and blood (14.9%). The results of antimicrobial susceptibility testing exhibited that the CRE strains were highly resistant to most commonly used antimicrobial agents in clinical practice, such as imipenem, meropenem and ertapenem, as well as penicillins and cephalosporins, etc. Conclusion The prevalence of CRE strains in children is increasing year by year, and their antimicrobial resistance to common antibacterial agents in clinical practice is extremely serious, to which serious attention needs to be paid. According to the results of antimicrobial susceptibility testings, the antibacterial agents should be rationally selected to effectively control the spread of CRE.

Objective To understand the thyroid stimulating hormone (TSH) level of neonates and iodine nutritional status of pregnant women and children in Guizhou Province.Metheds From 2016 to 2017,a city (district,county) in government location in Guizhou Province was selected as the urban survey site,and a county (city,district) whose economy was relatively backward and farther from the city (prefecture) in government location was selected as the rural survey site.In each survey site,300 salt samples were collected for determination of salt iodine;300 blood samples in the heel of neonates after birth 72 hours were taken for measurement of TSH.The Wodd Health Organization,United Nations International Children's Emergency Fund,and the International Committee for the Control of Iodine Deficiency (WHO/UNICEF/ICCIDD) recommend that when the proportion of neonates (TSH levels ＞ 5 mU/L) is ＜ 3％,the area is non-iodine-deficient.In other words,the 97th percentile (P97) value should be ≤5 mU/L.The normal reference value of the kit is ≤9 mU/L.And urinary iodine of 150 children aged 8-10 and 150 pregnant women was determined.Results A total of 5 400 edible salt samples were tested,the median of salt iodine was 27.9 mg/kg,and the consumption rate of qualified iodized salt was 94.89％ (5 124/5 400);5 400 neonatal heel blood samples were collected,the median of TSH was 2.62 mU/L,TSH P97 was 6.91 mU/L,and samples proportion with TSH ＞ 5 mU/L was 10.67％ (576/5 400),and ＞ 9 mU/L (the cut-off value of kit) was 1.00％ (54/5 400).Among 3 588 cases of children aged 8 to 10 years,the median of urinary iodine was 212.3 μg/L,those with urinary iodine ＜ 50 μg/L was 2.81％ (101/3 588),and ＜ 100 μg/L was 12.76％ (458/3 588).Among the 2 695 pregnant women,the median of urinary iodine was 163.1 μg/L,and 44.04％ (1 187/2 695) were ＜ 150 μg/L.Conclusions The quality of iodized salt is stable in Guizhou,the iodine nutrition status of children and pregnant women are good.The neonatal TSH and nutritional status of pregnant women should be monitored in the future.

Objective:To understand the salt sales situation and salt iodine content in the market of Guizhou Province 3 years after the system reform of salt industry.Methods:From August to October 2020, in 9 cities (prefectures) of Guizhou Province, 2 counties (cities and districts) were selected from each city (prefecture), 1 urban area and 1 township were selected from each county (city and district), 1 large supermarket and 1 farmers' market were selected in the urban area, and 1 small supermarkets or convenience stores were selected in the township, to check the varieties, place of origin and iodine content label on the package of salt sold, and different brands of salt were collected and sent to the provincial and county salt iodine laboratories. The iodine content was determined and analyzed.Results:A total of 18 large supermarkets, 18 farmers' markets and 18 small supermarkets or convenience stores were investigated, and 70 salt samples of 23 brands, 3 types and origin from 11 provinces were collected. Among them, there were 56 samples with iodine content of 21 - 39 mg/kg on the package. The iodine content range of provincial detection was 19.23 - 37.41 mg/kg (two of them were lower than 21.0 mg/kg), and the median was 25.75 mg/kg. There were 12 samples of two iodine contents (18 - 33 and 21 - 39 mg/kg) marked on the package, and the salt iodine range of provincial detection was 23.52 - 32.90 mg/kg, with a median of 26.55 mg/kg. One sample was marked with 18 - 33 mg/kg, and the iodine content of provincial detection was 25.20 mg/kg; the iodine content of 1 sample of non-iodized salt was not detected. According to the actual test value, iodine contents of 68 samples were within the range of packaging marks, accounting for 97.14% of the total. Taking the provincial test results as a standard, the absolute value of the relative deviation of the provincial and county test results was 0 - 27.45%, the average deviation was 7.65%, and the coincidence rate was 91.43% (66/70). The county test results were acceptable.Conclusions:After the system reform of salt industry, there are many kinds of salt which come from many provinces, and more than 97% of the salt iodine content which is within the standard range of salt concentration in Guizhou Province.

Objective:To observe the clinical outcomes of continued pregnancy in pregnant women with cesarean scar pregnancy (CSP).Methods:A retrospective analysis was performed on the pregnancy outcomes of 55 pregnant women who were diagnosed with CSP at the Second Affiliated Hospital of Army Medical University during the first trimester of pregnancy from August 1st, 2018 to October 31st, 2021 and strongly requested to continue the pregnancy.Results:Of the 55 pregnant women, 15 terminated the pregnancy in the first trimester, 1 underwent hysterotomy at 23 weeks of gestation due to cervical dilation, and 39 (71%, 39/55) continued pregnancy to the third trimester achieving live births via cesarean section. The gestational age of the 39 pregnant women delivered by cesarean section was 35 +6 weeks (range: 28 +5-39 +2 weeks), of whom 7 cases at 28 +5-33 +6 weeks, 20 cases at 34-36 +6 weeks, and 12 cases at 37-39 +2 weeks. The results of pathological examination were normal placenta in 3 cases (8%, 3/39), placenta creta in 4 cases (10%, 4/39), placenta increta in 9 cases (23%, 9/39) and placenta percreta in 23 cases (59%, 23/39). Among the 36 pregnant women who were pathologically confirmed as placenta accreta spectrum disorders (PAS) after surgery, the last prenatal ultrasonography showed placenta previa in 27 cases (75%, 27/36) and not observed placenta previa in 9 cases. The median intraoperative blood loss, autologous blood transfusion, and allogeneic suspended red blood cell infusion of 39 pregnant women during cesarean section were 1 000 ml (300-3 500 ml), 300 ml (0-2 000 ml) and 400 ml (0-2 400 ml), respectively. The uterine preservation rate was 100% (39/39), and only 1 case received cystostomy due to intracystic hemorrhage. The birth weight of the newborn was 2 580 g (1 350-3 800 g), and 1 case of mild asphyxia. Conclusions:Pregnant women with CSP who continue pregnancy under close monitoring after adequate ultrasound evaluation and doctor-patient communication could achieve better maternal and infant outcomes, but pregnant women with CSP are highly likely to continue pregnancy and develop into PAS. Effective hemostasis means and multidisciplinary team cooperation are needed in perinatal period for ensuring maternal and fetal safety.

Objective To investigate the resistance profile of clinical bacterial isolates to antibiotics in Shanghai during 2016.Methods Antimicobial susceptibility testing was carried out for the clinical isolates collected from 47 hospitals according to a unified protocol using Kirby-Bauer method or automated systems.The participating hospitals included 28 tertiary hospitals and 19 secondary hospitals across Shanghai.Results were analyzed according to CLSI 2016 breakpoints.Results A total of 122 548 clinical isolates were collected,including 35 522 (29.0％) strains of gram positive cocci and 87 026 (71.0％) strains of gram negative bacilli.Overall,28.9％ of the isolates were from secondary hospitals and 71.1％ from tertiary hospitals.Gram positive and gram negative isolates accounted for 25.8％ and 74.2％ in secondary hospitals,30.3％ and 69.7％ in tertiary hospitals,respectively.The overall prevalence of MRSA in Staphylococcus aureus was 48.7％ and 77.2％ of MRCNS in coagulase-negative Staphylococcus.The average prevalence of MRSA and MRCNS was 55.9％ and 73.3％ in secondary hospitals,45.9％ and 78.6％ in tertiary hospitals.No strains were found resistant to vancomycin in Staphylococcus.About 77.4％ of the 1 111 strains of non-meningitis S.pneumoniae isolated from children were penicillin-susceptible (PSSP),13.2％ were penicillin-intermediate (PISP) and 9.4％ were penicillinresistant (PRSP).The prevalence of PSSP,PISE and PRSP was 97.8％,2.2％,and 0 in secondary hospitals,76.5％,13.7％,and 9.8％ in tertiary hospitals.Of the 285 strains isolated from adults,94.0％,4.2％ and 1.8％ were PSSP,P1SP and PRSP,respectively.The prevalence of PSSP,PISP and PRSP among the isolates from adults was 93.7％,5.3％,and 1.0％ in secondary hospitals,94.2％,3.7％,and 2.1％ in tertiary hospitals.Overall,37 strains of vacomycin-resistant E.feacium (14 from secondary hospitals and 23 from tertiary hospitals) and 25 strains of vacomycin-resistant E.feacalis (all from tertiary hospitals) were identified.PCR and sequencing analysis indicated that most of these resistant strains were vanA type.The overall prevalence of ESBLs-producing srains was 52.2％ in E.coli,30.9％ in Klebsiella pneumoniae and 29.8％ in Proteus mirabilis.Specifically,the corresponding prevalence of such strains was 55.1％,33.6％ and 34.0％ in secondary hospitals,51.0％,29.7％ and 28.0％ in tertiary hospitals,respectively.Enterobacteriaceae strains were still highly susceptible to carbapenem antibiotics.Overall,8.9％ and 9.1％ of the Enterobacteriaceae strains were resistant to imipenem and meropenem,respectively.The figure was 6.6％ and 7.1％ in secondary hospitals,9.9％ and 10.0％ in tertiary hospitals.Extensively drug-resistant strains were identified in A.baumannii,K.pneumoniae,P.aeruginosa,and E.coli,specifically,223,63,10,and 4 strains in secondary hospitals;224,201,22,and 9 strains in tertiary hospitals.Conclusions Antibicotic resistance is still very serious in the common clinical strains,which poses a critical threat to healthcare facilities.This issue should be taken seriously and effective infection control measures must be put in place.
