In infants with severe bronchopulmonary dysplasia(sBPD),severe pulmonary lobar emphysema may occur as a complication,contributing to significant impairment in ventilation.Clinical management of these infants is extremely challenging and some may require lobectomy to improve ventilation.However,prior to the lobectomy,it is very difficult to assess whether the remaining lung parenchyma would be able to sustain adequate ventilation postoperatively.In addition,preoperative planning and perioperative management are also quite challenging in these patients.This paper reports the utility of selective bronchial occlusion in assessing the safety and efficacy of lobectomy in a case of sBPD complicated by severe right upper lobar emphysema.Since infants with sBPD already have poor lung development and significant lung injury,lobectomy should be viewed as a non-traditional therapy and be carried out with extreme caution.Selective bronchial occlusion test can be an effective tool in assessing the risks and benefits of lobectomy in cases with sBPD and lobar emphysema.However,given the technical difficulty,successful application of this technique requires close collaboration of an experienced interdisciplinary team.

Objective: To characterize the incidence density of systematic lupus erythematosus (SLE) in Yinzhou District of Ningbo from 2016 to 2021, and compare the age and gender specific differences. Methods: A retrospective cohort study was conducted based on the related data from 2015 to 2021 collected from the Health Information Platform of Yinzhou. Suspected SLE cases in local residents were identified by fuzzy matching of International Classification of Diseases 10^th edition code "M32" or Chinese text "lupus". The classification criteria from Systemic Lupus International Collaboration Clinics-2012 and The European League Against Rheumatism/American College of Rheumatology-2019 were used for case verification. SLE cases were identified with specific algorithm based on verification results, and new cases were identified with 1 year as the washout period. The incidence density and 95%CI were estimated by Poisson distribution. Results: From 2016 to 2021, a total of 1 551 921 permanent residents were registered in Yinzhou, in whom 51.52% were women. The M(Q₁,Q₃) age at enrollment was 40.38 (27.54, 53.54) years. The M(Q₁,Q₃) of follow-up person-years was 3.83 (0.41, 5.83) years. There were 451 new SLE cases, in which 352 were women (78.05%). The 6-year incidence density was 8.14/100 000 person-years (95%CI: 7.41/100 000 person-years-8.93/100 000 person-years) for the total population, 3.68/100 000 person-years (95%CI: 2.99/100 000 person-years-4.48/100 000 person-years) for men and 12.37/100 000 person-years (95%CI: 11.11/100 000 person-years- 13.73/100 000 person-years) for women. The incidence density in men appeared a small peak at 20-29 years old, and began to increase with age from 40 years old. The incidence density in women was highest in age group 20-29 years (16.57/100 000 person-years) and remained to be high until 30-79 years old. The incidence density of SLE in Yinzhou show no significant temporal trend from 2016 to 2021 (men: P=0.848; women: P=1.000). Conclusions: The incidence density of SLE in Yinzhou from 2016 to 2021 was similar to those of other areas in China. SLE has a high incidence in women, especially in the young and elderly, suggesting that more attention should be paid to the diagnosis and treatment of SLE in women.

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.

OBJECTIVE: To explore the appropriate procedures for preparing extracellular microvesicles (MV) derived from human mesenchymal stem cells (MSC). METHODS: Human MSCs from umbilical cords were cultured in a serum-free medium and maintained in a basal medium for 72 hours after the cell confluence reached to 80%. The supernatants of cultured cells were collected and MVs were enriched. MVs were identified by flow cytometry and electron microscopy. The total protein amount in MVs was used as a parameter for the content of MVs. The supernatants were adjusted to different pH values, and the output of MVs was detected. The supernatants were also collected for enriching the MV and detecting the protein content of MV after the cells were maintained in the basic medium for different time. RESULTS: Flow cytometric analysis showed that the MVs expressed CD9, CD63 and CD81, morphologically presented round under an electron microscope and the diameter of MV was around 100 nm. After enrichment of MV, the protein content of MVs in the supernatants was 416.8±128.1, 255.4±77.9 and 142.8±46.4 μg per 10 MSC，respectively at pH of supernatant 3, 7 and 9 (P＜0.05). The protein content of the supernatants per 10 MSC was 173.6±44.5, 262.4±49.6 and 364.2±37.8 μg respectively after starvation culture for 48, 72 and 96 hrs (P＜0.05). CONCLUSION MVs can be readily collected after MSCs were starved for 96 hours, and the pH of the supernatants is adjusted at 3.0.

【Abstract】 【Objective】To assess effect of calcofluor white and fluorescent dye labeled concanavalin A in Candida albicans growth and adhesion of cells.【Methods】Yeast cells of 20 strains of Candida albicans were labeled by calcofluor white and Alexa fluor 488 conjugated concanavalin A respectively. The growth of labeled Candida albicans were tested by counts of colony forming unit. Then yeast cells of Candida albicans were co-cultured with macrophages and enterocytes for half an hour. The adhesion of labeled Candida albicans to macrophages and enterocytes were observed by fluorescence microscopy.【Results】No difference was observed on the number of colony forming units between calcofluor white-labeled groupand control group(P=0.942). Also,no difference was observed on the number of colony forming units between Alexa fluor 488 conjugated concanavalin A-labeled group and control group. However,either the number of calcofluor white-labeled Candida albicans or Alexa fluor 488 conjugated concanavalin A-labeled Candida albicans that bound to macrophages was less than that in control group(P=0.000,respectively). Either the number of calcofluor white-labeled Candida albicans or Alexa fluor 488 conjugated concanavalin A-labeled Candida albicans that bound to enterocytes was less than that in control group(P = 0.000,respectively). Hyphae were observed in control group but not in calcofluor white group after yeast cells of Candida albicans were co-cultured with cells for half an hour.【Conclusions】Growth of Candida albicans was not changed,while its adhesion to cells was reduced after its labeling by calcofluor white and Alexa fluor 488 conjugated concanavalin A.The germination of Candida albicans was affected when it had been labeled by calcofluor white.

Diemailing~® Kudiezi Injection( DKI) is widely used in the treatment of cerebral infarction,coronary heart disease and angina pectoris. Long-term clinical application and related research evidence showed that DKI has a good effect in improving the clinical symptoms of cardiovascular and cerebrovascular diseases. However,this injection has not been included in any clinical practice guideline. It has been found that the use of DKI is in wrong way in clinical practice in recent years. Therefore,clinical experts from the field of cardiovascular and cerebrovascular diseases nationwide are invited to compile this expert consensus in order to guide clinicians.GRADE system is used to grade the quality of evidence according to different outcomes according to degrading factors. Then it forms the recommendation or consensus suggestion through the nominal group method. The formation of expert consensus mainly considers six factors: quality of evidence,economy,efficacy,adverse reactions,patient acceptability and others. Based on these six aspects,if the evidence is sufficient,a " recommendation" supported by evidence is formed,and GRADE grid voting rule is adopted. If the evidence is insufficient,a " consensus suggestions" will be formed,using the majority voting rule. In this consensus,the clinical indications,efficacy,safety evidences and related preliminary data of DKI were systematically and comprehensively summarized in a concise and clear format,which could provide valuable reference for the clinical use of DKI. This consensus has been approved by China association of Chinese medicine which is numbered GS/CACM 202-2019.

OBJECTIVE: The aim of this study was to analyze the mediating effect of body dissatisfaction in correlation between obesity and dietary behavior changes for weight loss (DBCWL). METHODS: A total of 680 primary and middle school students were included in this study. Their body height, weight, and waistline were effectively measured, and they were also evaluated to assess their body dissatisfaction, perception of dietary behaviors, and DBCWL. The correlation among these factors was analyzed using mediating effect models. RESULTS: The prevalence of overweight/obesity and abdominal obesity was significantly higher in males than in females (P < 0.05). Overweight/obesity, abdominal obesity, and body dissatisfaction significantly increased the risk for DBCWL (OR = 2.57, 2.77, and 1.95, respectively). Overweight/obesity and abdominal obesity significantly increased the risk for body dissatisfaction (OR = 6.00 and 4.70, respectively). Significant mediating effects of body dissatisfaction were observed in correlation between overweight/obesity and DBCWL and between abdominal obesity and DBCWL (OR = 2.20 and 1.92, respectively; P < 0.05), and the proportions of mediating effects among the total effects were 48.89% and 46.60%, respectively. CONCLUSION Body dissatisfaction might play an important mediating effect in association between DBCWL and obesity, which indicates that guiding children to correctly recognize their body might be more conducive than promoting obese children toward weight loss through dietary behavior changes.

BACKGROUNDOccult invasive cervical cancer discovered after simple hysterectomy is not common, radical parametrectomy (RP) is a preferred option for young women. However, the morbidity of RP was high. The aim of our study is to assess the incidence of parametrial involvement in patients who underwent radical parametrectomy for occult cervical cancer or radical hysterectomy for early-stage cervical cancer and to suggest an algorithm for the triage of patients with occult cervical cancer to avoid RP.

METHODSA total of 13 patients with occult cervical cancer who had undergone RP with an upper vaginectomy and pelvic lymphadenectomy were included in this retrospective study. Data on the clinicopathologic characteristics of the cases were collected. The published literature was also reviewed, and low risk factors for parametrial involvement in early-stage cervical cancer were analyzed.

RESULTSOf the 13 patients, 9 had a stage IB1 lesion, and 4 had a stage IA2 lesion. There were four patients with grade 1 disease, seven with grade 2 disease, and two with grade 3 disease. The median age of the entire patients was 41 years. The most common indication for extrafascial hysterectomy was cervical intraepithelial neoplasia 3. Three patients had visible lesions measuring 10-30 mm, in diameter and ten patients had cervical stromal invasions with depths ranging from 4 to 9 mm; only one patient had more than 50% stromal invasion, and four patients had lymph-vascular space invasion (LVSI). Perioperative complications included intraoperative bowel injury, blood transfusion, vesico-vaginal fistula, and ileus (1 case for each). Postoperative pathologic examination results did not show residual disease or parametrial involvement. One patient with positive lymph nodes received concurrent radiation therapy. Only one patient experienced recurrence.

CONCLUSIONSPerioperative complications following RP were common, whereas the incidence of parametrial involvement was very low among selected early-stage cervical cancer patients. Based on these results, we thought that patients with very low-risk parametrial involvement(tumor size ≤ 2 cm, no LVSI, less than 50% stromal invasion, negative lymph nodes) may benefit from omitting RP. Further prospective data are warranted.
