Objective: To conduct a systematic review and meta-analysis of studies evaluating the oncological and fertility outcomes of early-stage endometrial cancer (EC) treated with the levonorgestrel-releasing intrauterine system (LIUS)-based regimens. Methods: The Meta-analyses Of Observational Studies in Epidemiology statement for meta-analyses was followed. Searches were conducted on MEDLINE, Embase, PubMed, Preprints, and the Cochrane Central Register of Controlled Trials from January 1990 to August 4, 2022. The Joanna Briggs Institute Critical Appraisal Checklist was used for quality assessment. The primary endpoint was the complete response (CR) rate and the secondary endpoints were relapse, pregnancy, and live birth rate. Results: A total of 25 studies (821 women) were included. The CR rate of LIUS-based regimens was 63.4% (95% confidence interval [CI]=52.3%–73.2%), with 29.6% (95% CI=23.3%–36.8%) of cases experiencing recurrence during follow-up. In sensitivity analyses, patients younger than 45 years of age with a body mass index <30 kg/m2 who were treated with LIUS-based regimens achieved a high CR rate of 84.6% (95% CI=80.3%–88.1%) over a median follow-up of more than 24 months. Overall pregnancy and live birth rates were 37.9% (95% CI=24.1%–53.9%) and 39.3% (95% CI=24.0%–57.0%), respectively. No statistical differences were apparent in CR or relapse rates among the LIUS+GnRH agonist, LIUS+oral progesterone, or hysteroscopic resection followed by LIUS subgroups. Conclusion LIUS-based therapies are viable for the conservative management of early-stage endometrioid EC on CR and fertility outcome.

Objective:To study clinical pathological characteristics, immunohistochemical, molecular genetical changes and prognosis in pediatric eosinophilic solid and cystic renal cell carcinoma (ESC RCC) with TSC2 gene mutations.Methods:The tissue samples were collected from two pediatric ESC RCC patients between 2017 and 2018. The tissues were subjected to histological examination and immunohistochemistry using EnVision system. The TFE3, TFEB gene rearrangements were tested using FISH and molecular genetic study. The paraffin sections were used for DNA extraction, PCR amplification and NGS sequencing.Results:The two patients with ESC RCC were both male, aged at 9 years and 8 months, and 13 years, respectively. The tumors were from the right kidney, 5 cm and 7 cm in size, respectively, with solid and cystic changes in cross section, and grey-reddish or grey-whitish fish meat appearance. Microscopic observation revealed the tumors had fibrous capsules, which were infiltrated by the tumor cells. The tumor cells were diffusely distributed, round-shaped, or polygon-shaped, and had voluminous cytoplasm, eosinophilic cytoplasm, various sizes of vacuoles and clear cell-like appearance. There were papillary structures in some areas, with visible fiber septa. The nuclei were round and vesicular, with multi-nucleated cells and megakaryocytes. The mitoses were not seen. A few cystic structures were visible in different sizes, and capsule walls were covered with a single layer of spike-like tumor cells. Thick-walled blood vessels were seen in the stroma, with focal lymphocytic infiltration, eosinophilic necrosis, calcifications and cholesterol crystals. Immunohistochemistry of the tumor cells was positive for PAX8 (diffuse), CK20 (focal), CKpan (focal), CK10 (1 focal, 1 diffuse), INI1, vimentin, CD68, and Ki-67 (5%~10%); the tumor cells were negative for HMB45, S-100, Melan A, p53, desmin, TFE3, CK7, CK19, EMA, CD56, CgA, Syn, CD30, CD117, WT1 and SMA. Molecular genetic study showed that TFE3 and TFEB gene rearrangements were not detected by FISH. NGS sequencing showed TSC2 p.Lys574Ter (0.198) was found in patient one and TSC2 p.Arg406Ter (0.355) in patient two.Conclusions:ESC RCC in children is a rare disease, and can be misdiagnosed easily. It has unique pathological characteristics, and immunohistochemical, molecular and genetic changes. The prognosis is relatively good.

Objective: To explore the clinical application value of enhanced recovery after surgery (ERAS) in the laparoscopic surgery for cholecystolithiasis comorbid with choledocholithiasis. Methods: The prospective study was conducted. The clinicopathological data of 52 patients with cholecystolithiasis comorbid with choledocholithiasis who were admitted to the Third Affiliated Hospital of Zunyi Medical University from September 2016 to September 2018 were collected. Patients were divided into 2 groups by random number table: patients in observation group received laparoscopic cholecystectomy + choledocholithotomy + choledochoscopic exploration + T-tube drainage (or primary suture of common bile duct) and perioperative management guided by the concept of enhanced recovery after surgery (ERAS), and patients in control group received traditional perioperative management. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) postoperative complications; (4) postoperative pain scores; (5) changes in hepatic function and blood routine during perioperative period. Follow-up using outpatient examination and telephone interview was performed to detect complications during the postoperative 6 months up to March 2019. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the paired t test or repeated ANOVA. Count data were described as absolute numbers and percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results: Fifty-two patients were screened for eligibility, including 20 males and 32 females, aged 25-68 years, with an average age of 53 years. There were 30 patients in the observation group and 22 in the control group. (1) Surgical situations: the operation time and volume of intraoperative blood loss were (133±19)minutes and (47±21)mL in the observation group, and (136±22)minutes and (49±23)mL in the control group, respectively, showing no significant difference between the two groups (t=-0.386, -0.211, P>0.05). (2) Postoperative situations: time to out-of-bed activity, time to initial food intake, time to first anal flatus, duration of postoperative hospital stay, and hospital expenses were (18±4)hours, (19±5)hours, (28±2)hours, (4.0±1.0)days, and (1.82±0.22)×10⁴ yuan in the observation group, and (29±7)hours, (46±9)hours, (37±4)hours, (6.6±1.6)days, and (2.25±0.29)×10⁴ yuan in the control group, respectively, showing significant differences between the two groups (t=-7.054, -14.169, -9.426, -6.582, -5.809, P<0.05). (3) Postoperative complications: 1 of 30 patients in the observation group had postoperative biliary leakage, with a postoperative complication rate of 3.3%, and was cured after symptomatic support treatment. Six of 22 patients in the control group had postoperative complication, with a postoperative complication rate of 27.3%, including 2 of biliary leakage, 1 of hemorrhage, 1 of abdominal infection, 1 of pulmonary infection, 1 of urinary infection, and they were cured after symptomatic support treatment. There was a significant difference between the two groups (χ²=4.358, P<0.05). (4) Postoperative pain scores: from postoperative 6 hours to 48 hours, the postoperative pain score changed from 2.4±0.7 to 1.9±0.9 in the observation group, and from 4.1±0.7 to 2.9±0.9 in the control group, respectively, showing a significant difference in the changing trend between the two groups (F=78.053, P<0.05). (5) Changes in hepatic function and blood routine during perioperative period: from preoperation to postoperative 3 days, levels of alamine aminotransferase (ALT), aspartate transaminase (AST), gamma-glutamyltransferase (GGT), total bilirubin (TBil), and count of white blood cells in the observation group changed from (77±20)U/L to (53±12)U/L, from (85±22)U/L to (61±17)U/L, from (166±39)U/L to (55±24)U/L, from (40±13)μmol/L to (29±12)μmol/L, from (7.0±2.0)×10⁹/L to (6.8±1.9)×10⁹/L, and changed from (79±23)U/L to (62±14)U/L, from (88±24)U/L to (64±17)U/L, from (179±34)U/L to (74±29)U/L, from (45±13)μmol/L to (35±12)μmol/L, from (7.9±2.4)×10⁹/L to (7.5±1.9)×10⁹/L in the control group, respectively. The levels of ALT, AST, GGT, TBiL, and count of WBC showed increasing at postoperative 1 day, and decreasing at postoperative 3 days. There was no significant difference in the changing trend between the two groups (F=0.058, 0.471, 3.021, 1.593, 2.172, P>0.05). Conclusion ERAS is safe and effective in the laparoscopic surgery for choledocholithiasis comorbid with cholecystolithiasis.

Objective To observe the effect of sitagliptin on carotid intima-media thickness (c-IMT) and serum hs-CRP and IL-6 levels in the patients with newly diagnosed type 2 diabetes mellitus. Methods 65 patients with newly diagnosed type 2 diabetes mellitus who were admitted to the outpatient clinic and were hospitalized in our hospital were selected. They were randomly divided into sitagliptin phosphate tablet group (experimental group) with 35 cases and metformin hydrochloride tablet group (control group) with 30 cases. All patients were given health education about diabetes, diet guidance and exercise. All patients were given drawing of venous blood at a fasting condition ≥10 h before treatment and 6 months after treatment to determine the following indicators: FPG, 2 hPG, hs-CRP, IL-6, TC, TG, HDL-c, LDL-c, HbA1 c, hs-CRP, IL-6, etc, and c-IMT was determined. Results There was no statistically significant difference in blood glucose, blood lipids, inflammation index and c-IMT between the two groups before treatment (P>0.05); after treatment, FPG, 2 hPG and HbA1 c were significantly lower than those before treatment in both groups, and the difference was statistically significant (P<0.01). There were statistically significant differences in FPG and HbA1 c between the two groups (P<0.01). There was no statistically significant difference in 2-hour postprandial blood glucose between groups (P>0.05). The c-IMT, hs-CRP and IL-6 levels in the experimental group after treatment were significantly lower than those before treatment, and the differences were statistically significant (P<0.05). There was no significant change in c-IMT in control group after treatment (P>0.05). hs-CRP and IL-6 had a decreasing trend compared with those before treatment, and the difference was not statistically significant (P>0.05). There were statistically significant differences in c-IMT, hs-CRP and IL-6 between the two groups after treatment (P<0.05). Spearman linear correlation analysis: c-IMT was positively correlated with hs-CRP levels and IL-6 (r=0.6585, P=0.000; r=0.571, P=0.000). There was no significant correlation between fasting blood glucose and glycosylated hemoglobin (P>0.05). Conclusion The DPP-4 inhibitor of sitagliptin has a clear hypoglycemic effect and can reduce c-IMT, hs-CRP and IL-6. The anti-inflammatory effects besides hypoglycemic effect may be involved in the reduction of atherosclerosis in the patients with diabetes mellitus.

Objective To investigate the effects of enteral nutritional emulsions on glucose and lipid metabolism in elderly patients with diabetes.

Results Compared with baseline levels , FBG and HbA1c declined in the TPF-DM group[(5.70 ± 0.69)mmol/L vs .(7.90 ± 1.71)mmol/L and (6.39 ± 1.11)% vs .(7.92 ± 1.50)%,all P＜0.05]and the TPF-D group[(5.72 ± 1.12)mmol/L vs . (7.63 ± 1.73 )mmol/L and (6.86 ± 0.97 )% vs .(7.81 ± 1.04 )%,all P＜ 0.05 ]after 3 months of treatment ,but no significant difference was found between these two groups. The TPF-DM ,TPF-D , TPF-T groups showed significantly narrower fluctuation ranges of 24 h blood glucose levels after 3 months[(2.20 ± 0.88)mmol/L vs .(4.43 ± 2.07)mmol/L ,(2.94 ± 1.16)mmol/L vs .(4.22 ± 1.60) mmol/L ,(3.21 ± 1.64)mmol/L vs .(4.36 ± 1.88)mmol/L ,all P ＜ 0.05).Serum albumin levels increased in all four groups ,compared with baseline levels (all P＜0.05) ,but there was no significant difference between the groups(all P＞0.05). Furthermore ,the serum HDLC level increased in all four groups than baseline (all P＜ 0.05). Conclusions Enteral nutritional emulsions containing slow release starch and fructose ,dietary fibers and proper ω6 and ω3 ratio can stabilize blood sugar ,regulate blood lipids ,and improve nutritional status.

Objective To investigate the clinicopathologic features of intestinal polypoid lymphoma (PL) in children. Methods The clinicopathologic data of 15 cases of pediatric intestinal PL in Jiangxi Provincial Children 's Hospital were retrospectively analyzed. Immuohistochemistry was used to detect the expressions of CD10, bcl-6, bcl-2, MUMl and ERCC1, then EB virus (EBV)-encoded RNA (EBER) status was tested by using in situ hybridization. Results Amongst 15 cases studied, 13 cases were Burkitt lymphoma (BL), 1 case was diffuse large B-cell lymphoma (DLBCL) and 1 case was between DLBCL and BL (DLBCL/BL). The positive rate of CD10, bcl-6, bcl-2, MUMl, ERCC1 and EBER were 100.0%(13/13), 92.3%(12/13), 0, 7.7 % (1/13), 15.4 % (2/13), 53.8 % (7/13), respectively in 13 BL cases. The clinical stage of 13 patients with BL: 11 cases (84.6 %) Ⅱ stage, 1 case (7.7 %) Ⅲ stage, 1 case (7.7 %) Ⅳstage. The clinical stage of DLBCL and BL/DLBCL: Ⅱstage. 14 cases of PL had survival time without tumors, 24-120 months follow-up, and 1 BL patient inⅣstage without chemotherapy died after 2 months. Conclusion BL is a major subtype of intestinal PL in children, which shows a low clinical stage and a good prognosis.

OBJECTIVETo investigate the clinicopathologic features and differential diagnoses of non-involuting congenital hemangioma (NICH) in children.

METHODSThe clinical, morphologic and immunophenotypic characteristics of 22 cases of NICH were retrospectively analyzed.

RESULTSThe mean patients' age at diagnosis was 4.2 years, with a male to female ratio of 1.75:1. The tumors were located in the head and face (5 cases), neck (3 cases), body (6 cases), upper limbs (5 cases), and lower limbs (3 cases). Histologically, the tumor was dominated by rather large lobules of small vessels that were mostly rounded, curved, small and thin-walled, and were lined by endothelial cells surrounded by one or more layers of pericytes. The center of the lobules was occupied by one or more thin or thick walled vessels, which were surrounded by fibrous and fatty tissue, which contained abnormal arterial and venous structures. At the edge of the lobules there were lymphatic vessels. Immunohsitochemical study showed that tumor cells in NICH were positive for CD34 (22/22), CD31 (22/22), SMA (22/22), vimentin (22/22) and Glut1 (0/22). D2-40 expression was located at the edge of the capillary lobules.

CONCLUSIONSNICH is a benign lesion. Clinically and pathologically, it needs to be differentiated from rapidly involuting congenital hemangioma, infantile hemangiomas, tufted angioma, vascular malformation, and others.

OBJECTIVE: The aim of this retrospective study was to analyze the recovery rate of sudden sensorineural hearing loss in children, and explore the prognostic factors in order to guide the clinical diagnosis and treatment. METHOD: A retrospective review was conducted for the prognosis of children with sudden sensorineural hearing loss during the past 5 years (from November 2010 to May 2015) in Chinese PLA General Hospital. This paper have a complete clinical data of 101 patients (113 ears)with sudden hearing loss, ranging from 0 to 18 years old Patients were divided into four groups according to hearing recovery and eight putative prognostic factors were analyzed. RESULT: Among 101 patients (113 ears), the ratio of male and female was 60:53. Treatment was initiated from 1 to 183 days after disease onset, with an average of (18.5 ± 22.1) d. Bilateral and unilateral hearing loss were 24 ears and 89 ears, respectively. The proportion of mild hearing loss, moderate hearing loss, severe hearing loss and profound hearing loss were 7.1%, 6.2%, 23.9% and 62.8%, respectively. Vertigo and tinnitus occurred in 54.9% and 77.9% of the patients, respectively. After the treatment, the complete recovery rate was 9.7% and the overall recovery rate was 36.3%. The degree of hearing loss, earlier treatment onset, sex and bilateral involvement were significantly associated with hearing recovery (P < 0.05). CONCLUSION Sudden sensorineural hearing loss in children was generally identified as severe and profound hearing loss, but after positive and timely treatment, it can be improved or even cured. The mild hearing loss, earlier treatment onset, unilateral hearing loss and female were positive prognostic factors. The concurrence of tinnitus or vertigo, the results of ABR and DPOAE had no significant influence on prognosis.
