ABSTRACT

Objective:To summarize the clinical outcomes of en-bloc kidney transplantation from small infant donors to adult recipients at a single center.Methods:A total of 22 en-bloc transplantations from pediatric donors to adult recipients were performed from July 2013 to October 2017 in Institute of Organ Transplantation Affiliated Tongji Hospital Tongji Medical College Huazhong University of Science. Clinical data were retrospectively analyzed. The average age of 22 donors was (2.9±1.7) months with an average weight of (4.9±1.4) kg and 15 of them were aged under 3 months. The average weight of 22 adult recipients was (46.3±5.6) kg and most recipients were female. The causes of early graft failure and recipient death were examined during follow-ups. The recipients with functioning grafts post-transplantation were divided into single kidney survival group and en-bloc kidney survival group based upon the occurrence of unilateral vascular thrombosis. Medium/long-term renal graft function was compared between two groups.Results:Early graft failure occurred in 4 recipients. The causes were bilateral renal vascular thrombosis ( n=2), renal rupture ( n=1) and multiple organ failure followed by death ( n=1). Eighteen recipients were discharged after a recovery of renal graft function. One case had a removal of bilateral renal grafts due to new-onset graft tumor and another two died from interstitial pneumonia and complicate systematic disorder respectively during follow-ups. Among the remaining 15 recipients, 10 achieved bilateral renal survival (median follow-up: 59 months) and 5 unilateral renal survival (median follow-up: 48 months). The average eGFR of bilateral renal survival group was significantly higher than that of unilateral renal survival group at Year 1 post-transplantation (95±27 vs 61±24 ml/min/1.73 m 2, P<0.05) while the gap narrowed at Year 3 and there was no statistical significance (95±21 vs 69±31 ml/min/1.73 m 2, P=0.12). Conclusions:Although en-bloc kidney transplantation from infant donors can expand organ donor pool, there is a higher risk of early graft failure and unilateral renal vascular thrombosis. Nevertheless, satisfactory renal transplant outcomes may be achieved in patients with unilateral renal graft survival.

ABSTRACT

Objective:To apply real-time shear wave elastography to observe the effect of instrument-assisted soft tissue mobilization (IASTM) on Achilles tendons for healthy adults. Methods:From July to December, 2020, 52 healthy adults were assigned into control group (n = 15) and experimental group (n = 37) randomly. The experimental group received IASTM on left Achilles tendons, once another day for two weeks, while the control group received no treatment. The thickness and elastic modulus of the left Achilles tendons were measured with high-frequency ultrasound and shear wave ultrasound elastography on all the subjects, before treatment, immediately after the first treatment and three days after treatment, respectively. Results:Five cases dropped down in the experimental group. There was no significant difference in thickness and elastic Young's modulus of the left Achilles tendons between two groups before treatment (t < 0.630, P > 0.05). The thickness of the left Achilles tendons was less in the experimental group than in the control group immediately after the first treatment (t = 2.149, P < 0.05), while average and maximum elastic Young's modulus was less three days after treatment (t > 2.134, P < 0.05). Conclusion:Real-time shear wave elastography could quantify the thickness and elasticity of Achilles tendon, to evaluate the effect of IASTM.

ABSTRACT

OBJECTIVE@#To investigate the therapeutic effect of spleen low molecular weight extracts on epileptics hydrochloride-induced leukopenia in mice and explore its mechanism.@*METHODS@#The model of leukopenia in mice was established by the injection of epirubicin hydrochloride (10 mg/kg). After the injection of chemotherapeutic drugs, leukocytopenia mice were treated with different doses of spleen low molecular weight extract, Ganoderma oral solution and recombinant granulocyte colony stimulating factor (rhG-CSF). The general survival status indicators such as body weight, coat color and athletic ability of mice in each group were recorded; the tail vein blood of mice in each group was collected and the white blood cell count in them was calculated; bone marrow of mice was taken and bone marrow smears were observed.@*RESULTS@#In the model group, the weight of the mice gradually decreased in the later period, their coat became dark and rough, and the ability to exercise decreased, while the mice in the treatment groups showed different degrees of improvement in their survival status except for the mice treated by rhG-CSF. There was no significant fluctuation in the white blood cell count of the blank control mice. After injection of epirubicin, the white blood cell count of peripheral blood in the model mice and treated mice were decreased. The white blood cell count was lower in the mice treated with high-dose low molecular weight extract and rhG-CSF than that in other experimental groups. Bone marrow smear showed that the proportion of bone marrow nucleated cells in the mice treated with the low molecular weight extract of the spleen was significantly higher than that of model mice (P<0.05).@*CONCLUSION@#The low molecular weight spleen extracts can significantly improve the hematopoietic state of mouse bone marrow, promote the proliferation of inhibited bone marrow cells, and thus has the effect of treating leukopenia in mice.

ABSTRACT

BACKGROUND@#It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011.@*METHODS@#A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided).@*RESULTS@#The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107).@*CONCLUSIONS@#The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly.@*TRIAL REGISTRATION NUMBER@#NCT03620565, https://register.clinicaltrials.gov.

ABSTRACT

Objective:To investigate the effect of Huoxue Jiedu Runzao prescription on the morphology, apoptosis, and function of submandibular gland in the mouse model of Sjögren's syndrome (SS) and its functioning mechanism, we analyzed the expression of the apoptosis inhibitor Survivin in the submandibular gland cells of SS mice. Method:Female BALB/c57 mice were selected as the normal group. The naive non-obese diabetic (NOD/Ltj) female mice were selected as the SS model, which were randomly assigned into the model group, Paeoniae Radix Alba total glucosides capsule (0.234 g·kg<sup>-1</sup>) group, and low-, medium-, and high-dose (15.6, 31.2, 62.4 g·kg<sup>-1</sup>, respectively) Huoxue Jiedu Runzao prescription groups. Each group had 15 mice. The morphological and functional changes of submandibular gland and the Survivin expression were observed and measured after 8 weeks of drug intervention. Survivin expression was determined by immunohistochemistry (IHC), Western blot, and reverse transcription-polymerase chain reaction (RT-PCR). Result:Compared with normal group, salivary flow and submandibular gland index in model group were significantly decreased (<italic>P</italic><0.01), and histopathological score of submandibular gland was significantly increased (<italic>P</italic><0.01). Western blot showed that Survivin protein expression was significantly decreased (<italic>P</italic><0.05). IHC showed that, Survivin mRNA expression was significantly decreased (<italic>P</italic><0.01), and RT-PCR results showed that Survivin mRNA expression was significantly decreased (<italic>P</italic><0.01). Compared with model group, salivary flow and submandibular gland index of mice in Huoxue Jiudu Runzao prescription groups and Paeoniae Radix Alba total glucosides capsules groups were significantly increased (<italic>P</italic><0.05), histopathological score of submandibular gland was significantly decreased (<italic>P</italic><0.05), IHC results showed that Survivin expression was significantly increased (<italic>P</italic><0.01). Western blot and RT-PCR results showed that Survivin protein and mRNA expression of Huoxue Jiudu Runzao prescription high-dose group and Paeoniae Radix Alba total glucosides capsule group were significantly increased (<italic>P</italic><0.05). Conclusion:Huoxue Jiedu Runzao prescription can improve the secretion function of submandibular acinus, increase the submandibular gland index, and saliva secretion of SS mice by up-regulating survivin in submandibular gland cells of SS mice.

ABSTRACT

Objective:To summarize the clinical characteristics and therapeutic drug selection of post-transplantation diabetes mellitus(PTDM)after kidney transplantation in children.Methods:From May 2014 to March 2021, a total of 5 cases(5.38%)of 93 paediatric kidney transplant recipients with a median follow-up period of 34 months were diagnosed with PTDM in our centre.Retrospective data analysis was performed for these 5 paediatric recipients.The characteristics of the disease, treatment data and outcomes were summarized.Among the five paediatric recipients, one was male and four patients were female, ranging the age from 12 to 17 years.All recipients received a tacrolimus-based immunosuppressive regimen with prednisone discontinued no later than 3 months after kidney transplant.Results:The onset of PTDM ranged from 1 month to 46 months(median: 17 months)after transplantation.The blood glucose of two children returned to normal gradually after tacrolimus conversion to cyclosporine, with one of them was given insulin temporarily.Three children received oral hypoglycaemic agents, including one received acarbose, one received metformin, and one received metformin combined with acarbose.After a median follow-up of 6 months, the levels of blood glucose in five children were stable, and there was no significant change in serum creatinine and urine protein.Conclusions:The treatment of PTDM in children should be individualized with considering of age, gender and immunosuppressive regimen. Switch from tacrolimus to cyclosporine is effective. Metformin or other hypoglycemic agentsis helpful when tacrolimus is maintained.

ABSTRACT

Objective:To summarize the medium-term outcomes of single kidney transplantation from senile deceased donors aged above 65 years.Methods:Forty-three kidney recipients from donors aged above 65(old-aged donor group, OAD) and 43 kidney recipients of the same age and gender from donors aged 18 to 49 years(standard-criteria donor group, SCD) were retrospectively reviewed.The survival outcomes of patients and grafts, renal functions, the incidence of delayed graft function(DGF)and other complications were recorded within the 3-year follow-up post-transplantation.Results:The 3-year patient survival rates were 95.3% both in OAD and SCD and the 3-year death-censored graft survival rates 92.7% and 97.6% respectively.The serum levels of creatinine were significantly higher in OAD than that in SCD( P<0.05). And lower estimated glomerular filtration rate(eGFR)was found in OAD as compared with SCD( P<0.05). No significant difference existed in the incidence of DGF(OAD 20.9% and SCD 18.6%, P>0.05), acute rejection (OAD 4.7% and SCD 2.3%, P>0.05)or proteinuria(OAD 27.9%and SCD 14.0%, P>0.05). Conclusions:Single kidney transplantation from old-aged deceased donors may achieve excellent medium-term survival outcomes of patients and grafts.It can expand the donor pool though kidney functions were not as good as those of SCD.

ABSTRACT

Objective:To study the clinical characteristics of cornual pregnancy and compare the effects of various surgical methods on the outcomes.Methods:This was a single-center retrospective study. The clinical records of patients with cornual pregnancy who underwent surgery in Peking Union Medical College Hospital from June 2012 to December 2020 were collected. Surgical interventions included curettage (guided by ultrasound or monitored by laparoscope), and cornuostomy/cornectomy (the surgical approach by laparoscopy or laparotomy). The baseline data, perioperative treatment and whether persistent ectopic pregnancy (PEP) occurred after surgery were collected and analyzed statistically.Results:A total of 109 patients with cornual pregnancy diagnosed by surgical treatment were included in this study, whose average age was (32.9±4.8) years. Among them, the incidence of postoperative PEP was 16.5% (18/109). The risk of PEP in multipara was significantly higher than that in nulliparous women ( OR=7.639, 95% CI: 2.063-28.279, P=0.001). The risk of PEP in patients with the maximum diameter of lesion<1.5 cm was significantly higher than that in patients with the maximum diameter of lesion≥1.5 cm ( OR=8.600, 95% CI: 2.271-32.571, P=0.002). Among all surgical approaches for cornual pregnancy, the proportion of PEP in curettage under ultrasound monitoring was the highest (56.0%, 14/25), which was higher than that in curettage under laparoscope monitoring (1/10; χ2=6.172, P=0.013); the proportion of PEP in curettage group (42.9%, 15/35) was higher than that in cornuostomy/cornectomy group (4.1%, 3/74; χ2=25.950, P<0.01). Neither salpingectomy in the operation nor the routine use of methotrexate (MTX) in perioperative period could significantly reduce the incidence of PEP (all P>0.05). Conclusions:Among the patients with cornual pregnancy, multipara, the maximum diameter of lesion<1.5 cm and ultrasound-guided curettage are the risk factors of PEP after operation. Cornuostomy or cornectomy is recommended for patients with cornual pregnancy. If the patients would perform the curettage operation, laparoscopic monitoring is recommended. For patients with possible satisfactory operation outcome, it is not recommended to use MTX as a routine preventing measure.

ABSTRACT

Objective:To explore the risk factors of urinary incontinence (UI) in China by using random forest algorithm, and to evaluate the predictive effect of each risk factor on UI.Methods:A baseline survey with a multistage stratified cluster sampling design was conducted between February 2014 and January 2016, and followed up by telephone from June to December 2018. A total of 55 477 adult women from six provinces of China participated the survey. According to the ratio of 1:1, under sampling method was used to randomly select the same number of women as UI from the non UI women. The data were randomly divided into training set and verification set according to 7:3. The training set was used to establish the random forest model, which including the candidate variables with P<0.2 in univariate analysis, and the verification set was used to verify the predictive effects. Results:A total of 30 658 patients (55.26%, 30 658/55 477) completed the follow-up, the median follow-up time was 3.7 years. Among the 24 985 women without UI at baseline, 1 757 (7.03%, 1 757/24 985) had UI at followed up, including 1 117 (4.47%, 1 117/24 985) with stress UI, 243 (0.97%, 243/24 985) with urgency UI and 397 (1.59%, 397/24 985) with mixed UI. When fixed the number of features as 2 and the number of random trees as 300 in the random forest model, the out of bag error rate estimation was the lowest; with such parameter settings, the classification accuracy was 64.3%, the sensitivity was 64.2%, and the specificity was 64.4%. The top10 predictive UI factors that screening by the variable importance measure in random forest model were obtained as follows: age, parity, delivery pattern, body mass index (BMI), menopause, history of diabetes, education level, history of pelvic surgery, regions, and marital status.Conclusion:We identified the top10 predictive UI factors that screening by the variable importance in random forest model as follows: age, parity, delivery pattern, BMI, menopause, history of diabetes, education level, history of pelvic surgery, regions, and marital status.

ABSTRACT

A clinically reliable non-invasive test for endometriosis is expected to reduce the diagnostic delay. Although varieties of biomarkers have been investigated for decades, and cancer antigen-125, cancer antigen-199, interleukin-6, and urocortin were the most studied ones among hundreds of biomarkers, no clinically reliable biomarkers have been confirmed so far. Some emerging technologies including "omics" technologies, molecular imaging techniques, and microRNAs are promising in solving these challenges, but their utility to detect endometriosis has yet to be verified. New combinations of researched indicators or other non-invasive methods and further exploration of the emerging technologies may be new targets and future research hotspots for non-invasive diagnosis of endometriosis. In conclusion, researches of biomarkers for the detection of endometriosis are still ongoing and may benefit from novel molecular biology, bioinformatics methods and a combination of more diverse monitoring methods. Though it will be a daunting task, the identification of a specific set of diagnostic biomarkers will undoubtedly improve the status of endometriosis.

ABSTRACT

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

ABSTRACT

Objective:To summarize the transplant outcomes of pediatric kidney transplantation at a single center and discuss probable measures of improving the outcomes.Methods:A total of 111 pediatric renal transplantation were performed from September 2002 to September 2019. They were divided into adult-donor group ( n=41) and pediatric-donor group ( n=70). Adult-donor group consisted of two subgroups based upon donor sources: living-donor group ( n=19) and deceased-donor group ( n=22). Pediatric-donor group consisted of two subgroups based upon surgical types: single kidney group ( n=48) and en bloc kidney group ( n=22). Clinical data and outcomes of grafts and recipients were retrospectively analyzed. Results:The average age of recipients was (15.6±1.9) years in adult-donor group. None developed delayed graft function (DGF) in living-donor group whereas 6 patients (27.3%) had DGF in deceased-donor group ( P<0.05). During a follow-up period of 22-181 months, 1-year and 5-year graft survivals were 100% vs 94.1% and 93.8% vs 94.1% in living-donor and deceased-donor groups respectively. There were no statistical differences. In pediatric-donor group, the age of donors was significantly lower in en bloc subgroup than that in single kidney subgroup (median: 0.5 vs 6 months, P<0.05). The age of recipients was similar between two subgroups: (9.5±5.3) years in single kidney group vs. 11.5± 1.8 years in en bloc kidney group. In addition, 7 cases of single kidney were transplanted for infant recipients aged under 1 year. Vascular thrombosis occurred in 3 patients (6.3%) of single kidney group, less than that in 5 patients (22.7%) of en bloc kidney group ( P=0.06). During a follow-up period of 4-54 months, 1-year and 2-year graft survivals were 85% and 80% in single kidney group whereas 75% and 70% in en bloc kidney group. However, there was no statistically significant difference. One-year survival was 98% in single kidney group and 95% in en bloc kidney group. Conclusions:For elder pediatric recipients, excellent kidney transplant outcomes may be achieved with grafts from adult donors. For pediatric kidney recipients, transplant outcomes can be further improved with careful assessments and cautious usage of small grafts, particularly those form neonatal donors.

ABSTRACT

Objective:To explore the optimal keV for the visualization of rectal cancer and to investigate its diagnostic performance in the preoperative T staging of rectal cancer using virtual monoenergetic image (VMI) on a novel dual-layer spectral detector CT.Methods:Totally 43 patients with pathologically confirmed rectal cancer were involved in this retrospective study in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from May to October 2019. All the patients underwent novel dual-layer spectral detector CT scanning within 1 week before surgery. The 40, 50, 60, 70 keV VMI and 120 kVp conventional polyenergetic image (PI) were reconstructed based on the venous phase imagings. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the rectal cancer were measured and the image quality was scored using a 5-point scale to obtain the best keV VMI. Taking pathological results as golden standard, the accuracy rate of T staging was calculated and compared between the best keV VMI and 120 kVp PI. The CT attenuation, SNR and CNR were compared with one-way ANOVA analysis among the 5 groups of images.Image quality scores were assessed with Friedman test,and the accuracy rate was compared by McNemar test or Fisher exact test.Results:The SNR and CNR of rectal cancer at 40-70 keV VMI was better than 120 kVp PI ( P<0.05), the SNR at 40 keV VMI was the highest among all the VMI ( P<0.05), the CNR at 40 keV VMI was better, but there was no significant difference between 40 and 50 keV VMI ( P>0.05). The image scores at 40-60 keV VMI were all significantly superior to those of the 120 kVp PI ( P<0.001). 40 keV VMI was the best image. The accuracy rate of 40 keV VMI (67.4%, 29/43) was higher than that of 120 kVp PI (48.8%, 21/43) in the T stage ( P=0.008). The 40 keV VMI had a higher diagnostic accuracy rate (83.7%, 36/43) and specificity (58.8%, 10/17) in diagnosis of locally advanced rectal cancer (T3-4, P=0.016, 0.031). Conclusion:The image quality of novel dual-layer spectral detector CT at 40 keV VMI is good, which can improve the accuracy rate of preoperative T staging of rectal cancer.

ABSTRACT

Objective:To investigate the clinical features, etiology, and prognosis of sepsis during pregnancy and the postpartum period.Methods:Sixty-eight pregnant women with maternal sepsis treated in Peking Union Medical College Hospital from January 1997 to December 2019 were collected, and divided into obstetric infection group (30 cases) and non-obstetric infection group (38 cases) according to different infection sources. Clinical manifestations, types of infection sources, microbiological characteristics, treatment and outcomes were studied and analyzed.Results:(1) General conditions and clinical features: sepsis occurrence rate was 57% (39/68) and 43% (29/68) in prenatal and postpartum period, repectively. Statistical analysis showed that incidence of respiratory, renal, liver and coagulation dysfunction in non-obstetric infection group were significantly higher than those in obstetric infection group, and multiple organ dysfunction, cardiac arrest and blood lactate≥4 mmol/L were more common (all P<0.05). Sequential organ failure score in non-obstetric infection group was also significantly higher than that in obstetric infection group ( P<0.05). (2) Types of infection sources and microbiological characteristics: the most common maternal sepsis was genital tract sepsis (37%, 25/68). Chorioamnionitis was the most common cause in obstetric sepsis (40%, 12/30), while intra-abdominal infection was the most common cause in non-obstetric sepsis (34%, 13/38). Thirty-seven patients (54%, 37/68) were diagnosed as bloodstream infection (BSI). Gram-negative bacteremia accounted for 70% (26/37), the most common pathogen of which was Escherichia coli. BSI was most commonly secondary to a genital tract infection (65%, 17/26). (3) Treatment: the ICU hospitalization rates and the utilization rate of mechanical ventilation and vasoactive agents in non-obstetric group were higher than those in obstetric group with significant differences (all P<0.05). Thirty-two patients (47%, 32/68) underwent surgery to remove the infection sources, including 5 cases of hysterectomy. (4) Prognosis: the case fatality rate of maternal sepsis was 19% (13/68), which was significantly higher in the non-obstetric infection group (29%,11/38) compared with the obstetric infection group (7%,2/30; P=0.020). The time from diagnosis of sepsis to termination of pregnancy was (5.5±8.6) days in prenatal women, and time in obstetric infection group [(1.9±2.2) days] was significantly less than that of non-obstetric infection group [(7.7±10.3) days, P=0.029]. Adverse pregnancy outcomes were higher in the first and second trimester (72%, 18/25) than in the third trimester (21%, 3/14), and the difference was statistically significant ( P=0.002). Conclusions:Sepsis during pregnancy and the postpartum period is a potentially life-threatening disease. Pregnant women with non-obstetric sepsis have more complications, more serious condition and worse prognosis than those with obstetric infection. Timely detection of risk factors, early identification and active treatment are helpful to improve maternal and fetal prognosis.

ABSTRACT

Objective The HOTAIR gene is closely related to pannus formation in rheumatoid arthritis (RA). This study aimed to construct and screen fibroblast-like synoviocytes in human RA (HFLS-RA) stably overexpressing lncRNA HOTAIR, and to pave the way for further study of the role of lncRNA HOTAIR in the pathogenesis of RA. Methods LncRNA HOTAIR was cloned and linked to the PMT406 vector digested by BamHI-HF-HF and XhoI. The constructed plasmids were sequenced, identified and then transfected into 293T cells to pack lentivirus. The HFLS-RA cells were infected with the recombinant and empty vector lentiviruses, and purinomycin was employed to screen the lncRNA HOTAIR-overexpressed and control cell lines. The total RNA was extracted from the blank, negatively transfected and overexpressed cells by Trizol, and the cDNA obtained by reverse transcription was amplified by qPCR, followed by determination of the expression of lncRNA HOTAIR. Results The relative expression of lncRNA HOTAIR was significantly higher in the overexpression group than in the blank control and negative transfection groups (30.329 ± 3.860 vs 1.001 ± 0.048 and 0.892 ± 0.247, P 0.05). Conclusion The HFLS-RA cell line stably overexpressing lncRNA HOTAIR was successfully constructed, which has provided some experimental evidence for further investigation of the role of lncRNA HOTAIR in the pathogenesis of RA.

ABSTRACT

Objective To understand infection status of human immunodeficiency virus (HIV) and analyze the influencing factors among men who have sex with men (MSM) in Guangzhou. Methods Men who have sex with men (MSM) were recruited from 2014 to 2017. Face-to-face questionnaire survey was conducted to collect information of characterisitc and behaviors. Blood samples were used to detect HIV antibodie. Data were analyzed using SPSS 19.0. Results Among 2 419 MSM, 200(8.27%) participants were confirmed positive for HIV. Multivariate Logistic regression analysis showed that with Guangzhou and monthly economic income >0.5 million as reference, non-Guangzhou (OR=1.712, 95% CI: 1.176-2.492,P=0.005) and monthly economic income ≤0.5 million (OR=1.998, 95% CI: 1.409-2.833,P<0.001) were associated with HIV infection among MSM. Diagnosed syphilis (OR=2.461, 95% CI: 1.375-4.405,P=0.002) , undetected syphilis (OR=2.333, 95% CI: 1.635-3.331,P<0.001), anal sex role passive (OR=2.015, 95% CI: 1.244-3.267,P=0.004), both active and passive (OR=2.115, 95% CI: 1.374-3.251,P=0.001), non-using condoms every time during anal sex (OR=1.955, 95% CI: 1.374-2.781,P<0.001), non-fixed anal sex objects (OR=2.150, 95% CI: 1.463-3.160,P<0.001) were major risk factors for HIV infection among MSM. Conclusions The prevalance of HIV infection and high-risk sexual behavior were high among MSM in Guangzhou. It is urgent to expand the scope of HIV testing and advocate safe sexual behaviors among MSM.

ABSTRACT

BACKGROUND@#Trocar-site hernia (TSH) is a serious complication after laparoscopic procedures. Although it is a rare entity, it can have life-threatening consequences. This study aimed to retrospectively analyze the potential associated factors for TSH following gynecologic laparoscopy and summarize prevention strategies based on our experience.@*METHODS@#We searched for gynecological laparoscopic surgeries in the medical records system of Peking Union Medical College Hospital (PUMCH) from August 1998 to July 2018 and further sifted through the results for cases involving TSH. All included patients were divided into different groups according to patient characteristics, and the rate of TSH was compared among groups. Moreover, the detailed information of all patients with TSH was recorded and analyzed. Statistical analyses were performed with GraphPad Prism 6.@*RESULTS@#The approximate total rate of post-operative TSH among gynecologic laparoscopy procedures performed at PUMCH in the last 20 years was 0.016% (9/55,244). The rate of TSH was significant higher in elder patients (≥60 years old; 3/2686, 0.112%) than in younger patients (<60 years old, 6/52,558; 0.011%, P = 0.008). Moreover, the approximate rate of TSH was significantly higher after single-incision laparoscopic surgery (SILS, 2/534, 0.357%) than conventional laparoscopic surgery (7/54,710, 0.013%, P = 0.003). The average age of patients with TSH was 53.4 years (range, 35.0-79.0 years). Two of the nine patients had late-onset TSH following SILS; the other seven had early-onset TSH following conventional laparoscopy. Five TSH cases occurred at right lateral port sites, and the remaining three occurred at the umbilical port site. All patients underwent repair surgery, and one required small bowel resection.@*CONCLUSION@#Older age and SILS are potential associated factors for TSH development, while reducing excessive manipulation and improving suturing skills, especially at the umbilical trocar site following SILS and the right lateral trocar site, can avoid herniation.

ABSTRACT

Objective To evaluate the efficacy of tigecycline plus prolonged high-dose meropenem infusion in the prevention and treatment of early carbapenem-resistant Klebsiella pneumoniae (CRKP) infection after renal transplantation .Methods From January 2016 to December 2018 ,clinical data were retrospectively analyzed for 13 renal transplant recipients with graft-carried CRKP .The relevant clinical data included treatments and outcomes of grafts and recipients .KPC-2 gene was the only resistance gene detectable in all isolates of CRKP . Among 13 CRKP positive recipients ,there were positive cultures of graft preservation solution ,recipient blood & urine (n=1) , positive cultures of graft preservation solution & urine (n=1) ,positive cultures of graft preservation solutions & peri-graft drainage (n=3) ,continuous positive cultures of peri-graft drainage more than twice (n= 3) and positive culture of graft preservation solution (n= 5).All patients received tigecycline plus prolonged high-dose meropenem infusion-based antibiotics .Results Five patients with CRKP positive in preservation solution were successfully prevented from infection after a treatment period of (12 .4 ± 2 .1)days .Among another 8 cases ,additional topical medications (n= 3) and surgical debridement (n= 1) were used .It took a median time of 16 (7~60) days until a negative culture and the total antibiotic treatment course was 20 (10~93) days .The average hospitalization duration was (50 ± 35) days .During a median follow-up period of 25 (6~28) months ,there was no onset of renal arterial rupture ,graft nephrectomy or death .The survival rate was 100% for recipients and 92 .3% for grafts .Conclusions For post-transplant infections due to graft-carried KPC-2 producing CRKP ,rapid diagnostics and tigecycline plus prolonged high-dose meropenem infusion may optimize clinical outcomes by decreasing the rate of graft nephrectomy and the recipient mortality .
