OBJECTIVE: To evaluate the efficacy and safety of a hospital-made resuscitation pack, a Chinese medicinal herbal compound formula designed to enhance recovery in post-bronchoscopy patients. METHODS: In this randomized, single-blind, placebo-controlled clinical trial, eligible patients were randomly assigned 1:1 to either the treatment or control groups. The patients in the treatment group applied the resuscitation pack, which contained aromatic compounded Chinese herbs. The patients in the control group applied a hospital-made, single herb placebo pack. Packs were placed on the Tiantu (CV 22) acupuncture point for 4 h as soon as the bronchoscopy finished. Efficacy indicators, such as recovery time, patients' symptoms including nausea and dizziness, and adverse events (AEs) were observed and compared. The outcome indices were evaluated at baseline, 1 and 24 h after the bronchoscopy. Subgroup analysis was further performed by patients' age and depth of sedation. RESULTS: When applying generalized estimating equations (GEE) to evaluate the intensity of post-bronchoscopy nausea and vomiting, the intensity was lower in the treatment group (163 cases) compared with the control group (162 cases; 95% CI: 0.004, 0.099, P=0.03]. Also, significantly lower intensity of nausea was observed in the 60-70 years of age subgroup (95% CI: 0.029, 0.169, P=0.006) and deep sedation subgroup (95% CI: 0.002, 0.124; P=0.04). There was no significant difference in dizziness between two groups by GEE (95% CI: -0.134, 0.297; P=0.459). In addition, no serious AEs were observed in either group. CONCLUSIONS Our study found that the resuscitation pack markedly improved patients' symptoms by reducing nausea and vomiting after bronchoscopy without AEs, compared with placebo in the perioperative period.

ObjectiveTo investigate the mRNA expression levels of various aquaporins （AQPs） in luteinized granulosa cells from follicles of different diameters. MethodsFrom March 25， 2022 to September 23， 2022 in our reproductive medicine center， 48 women undergoing in-vitro fertilization （IVF） were enrolled and divided into the antagonist group and the agonist group according to the ovarian stimulation protocol. Follicular fluid samples were collected on the day of oocyte pick-up and granulosa cells were extracted from follicles of different diameters： small （<13 mm）， medium （13~18 mm） and large （≥18 mm）. After RNA quantification， 22 cases （66 samples） were included for analysis and mRNA expression levels of AQPs were compared among the three follicle groups. ResultsThe mRNA expression of aquaporin 2 （AQP2） in luteinized granulosa cells increased with the increase of follicle diameter （linear trend P = 0.004） and the difference was statistically significant between two groups of large and small follicles （P = 0.017）. Statistical difference was found in the antagonist group （P = 0.049 6）， but not in the agonist group （P = 0.108）. ConclusionThe mRNA level of AQP2 in luteinized granulosa cells increases with the increase of follicle diameter and its expression is related to the ovarian stimulation protocol， suggesting that AQP2 may play a role in follicle growth and follicular fluid formation， and its mRNA expression level may be regulated by follicle stimulating hormone （FSH） and luteinizing hormone （LH）.

ObjectiveTo explore the effect of Anmeidan on the sleep quality and serum levels of brain-derived neurotrophic factor （BDNF）， glial fibrillary acidic protein （GFAP）， and irisin in the patients with chronic insomnia. MethodA multicenter， randomized， double-blind， placebo-controlled clinical study was carried out， including 480 patients with chronic insomnia （deficiency syndrome） in Wuhan （Hubei）， Guangzhou （Guangdong）， and Lanzhou （Gansu）. They were randomized into an observation group and a control group at a ratio of 1∶1. The observation group was orally administered with Anmeidan granules at a dose of 11 g， 3 times per day， and the control group with Anmeidan simulant at a dose of 11 g， 3 times per day， Both groups of patients received sleep education after enrollment. After 4 weeks of medication， the Athens insomnia scale （AIS） scores， Spiegel scale scores， and serum levels of BDNF， GFAP， and irisin were compared between the two groups as well as between before and after treatment. ResultA total of 480 adult patients with chronic insomnia were enrolled in this study， with 64 patients falled off. Finally， the 415 patients were included in the analysis， including 213 patients in the observation group and 202 patients in the control group. There was no difference in age or sex between the two groups of patients. Compared with before treatment， the treatment in both groups decreased the AIS and Spiegel scores （P<0.01）. After treatment， the observation group had lower AIS and Spiegel scores than the control group （P<0.01）. The treatment in the observation group slightly lowered the level of BDNF， elevated the level of irisin （P<0.05）， and lowered the level of GFAP （P<0.05） in the serum. After treatment， the observation group showed higher level of irisin （P<0.05） and lower levels of BDNF and GFAP in the serum than the control group. ConclusionAnmeidan may improve the sleep quality of patients with chronic insomnia by elevating the irisin level and lowering the GFAP level in the serum.

Objective:To explore the risk factors of lymph node metastasis (LNM) in early gastric cancer (ECG), and establish a risk-prediction model based on LNM.Method:Four hundred and twenty-seven EGC patients undergoing curative radical gastrectomy were enrolled in this study. The risk factors for LNM of ECG were analyzed with Logistic regression. LNM risk was stratified and risk-predicting model was established. The risk-predicting model was measured by area under ROC curve. According to the same standard, clinical data of 133 patients with EGC who underwent radical surgery were selected for external verification of the model.Results:The frequency of LNM was 13.3% (32/427) in EGC patients. The LNM ratio of intramucosal carcinoma and submucosal carcinoma was 1.3% (3/237), 15.3% (29/190) respectively. Ulcer presence, tumor size >2 cm, undifferentiated tumor, submucosal invasion, neural invasion, and vascular tumor thrombus were significantly associated with LNM in EGC patients ( χ2=3.408, 16.379, 4.808, 29.804, 25.305, 47.120, respectively P<0.05). Multivariate analysis suggested that ulcer presence, tumor size >2 cm, depth of invasion, neural invasion, and vascular tumor thrombus were independent predictors of LNM in EGC patients, ( OR=0.326, 2.924, 11.824, 13.047, 7.756, respectively P<0.05). LNM predicting model is established, P=e^x/(1+e^x),x=-4.792-1.122 ulcer presence+1.073 tumor size+2.470 depth of invasion+2.569 neural invasion+2.048 vascular tumor thrombus,ROC-AUC of risk-predicting model was 0.845, the best cut-off was 0.094, the sensitivity was 72.70%, the specificity was 77.20%. The external verification result revealed the AUC of ROC was 0.840. The four-grid table is constructed by predicting model results and the postoperative pathological examination. The sensitivity and specificity of the model are calculated to be 82.35% and 68.96%, respectively. Conclusions:EGC patients with ulcer presence, tumor size >2 cm, depth of invasion, vascular tumor thrombus, and neural invasion have higher risk of LNM, the risk-predicting model can identify the high probability of LNM .

Objective:To study the safety and efficacy on timing of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) stageⅡbased on increase in remnant liver volume.Methods:19 patients (male: female 13: 6; average age 53 years) with liver tumors treated by ALPPS from April 2014 to December 2020 were retrospectively studied. Patients with FLV/ESLV (future liver volume/ estimated standard liver volume) increase of more than 50% within 1 week followed by stageⅡALPPS were included into the rapid group ( n=8). Those who failed to have 50% increase in FLV/ESLV within 1 week were included into the control group ( n=11). The two groups were compared in the ALPPS stage II in operating time, blood loss, postoperative complications, mortality rate and hospital stay. Results:All 19 patients underwent ALPPS stage II uneventfully. One patient in the control group died from liver failure within 30 days of operation. The operation time (3.2±1.8)h, blood loss (554±227) ml and postoperative hospital stay (12.6±2.4) d in the rapid group were significantly better than those in the control group (4.7±2.2) h, [(760±314) ml, (18.2±6.4) d (all P<0.05)]. The two groups had similar complication rates in both post stageⅠ[37.5%(3/8) vs. 45.4%(5/11)] , or stageⅡ [37.5%(3/8) vs. 36.4%(4/11)] (both P>0.05). Conclusion:Rapid increase in FLR volume of more than 50% within a week was safe and feasible to proceed to ALPPS stage II. This conclusion needs to be confirmed by further studies using large sample sizes.

Objective:To investigate the expression of KLF11 in gastric cancer tissues and cell lines as well as its effect on proliferation and apoptosis of human gastric cancer cells BGC823.Methods:Sixty pairs gastric cancer tissues and corresponding adjacent tissues were collected. The expression of KLF11 mRNA in gastric cancer tissues and their adjacent tissues was detected by RT-PCR. The expression of KLF11 was detected in gastric cancer cells. KLF11 expression was silenced. The proliferation of cells were detected by using MTT assay. Flow cytometry was used to detect the cell cycle and cell apoptosis rate. Western bloting was used to examine the changes of concentration of proteins associated with cell cycle,cell apoptosis and Wnt/β-catenin signaling pathway related proteins. The activity of Caspase3 enzyme was detected by spectrophotometry.Results:The relative expression of KLF11 mRNA in gastric carcinoma tissues was significantly higher than that of the adjacent tissues ( t=11.38, P<0.05). Its expression was related to tumor size, depth of invasion, lymph node metastasis and TNM clinical stage (all P<0.05). The proliferation of BGC823 cells was significantly suppressed after KLF11 silencing ( F=19.56, P<0.05), and the cell cycle was arrested in G 0/G 1 phase [(41.40%±0.98%) vs. (66.53%±1.01%), F=32.69, P<0.05]. Meanwhile, the apoptosis rate was significantly increased by KFL11 silencing [(41.44%±1.59%) vs. (15.42%±0.86%), F=35.35, P<0.05]. The results of Western blotting revealed that the expression of Bax and Cleaved Caspase3 was significantly increased ( F=23.33, 33.63; both P<0.05), wheras that of β-catenin, Bcl-2, CyclinD1and CyclinE was significantly reduced ( F=22.21, 16.24, 26.75, 33.42; all P<0.05). The activity of Caspase3 enzyme was enhanced ( F=16.56, P<0.05). Conclusion:KLF11 was highly-expressed in gastric cancer tissues and cells, KFL11 silencing could inhibit gastric cancer cells proliferation and induce cell apoptosis via Wnt/β-catenin signaling pathway.

Objective:To construct a computed tomography (CT)-based three-dimensional digital model of small bowel, and investigate its application value for predication of small bowel length before bariatric surgery.Methods:The retrospective and descriptive study was conducted. The clinical data of 3 patients with obesity who were admitted to the Daping Hospital of Army Medical University from December 2018 to January 2019 were collected. There were 2 males and 1 female, aged from from 24 to 44 years, with a median age of 25 years. Patients underwent abdominal enhanced CT examination before operation, and the three-dimensional digital models of small bowel for each patient were constructed respectively. Of the 3 patients, 2 underwent sleeve gastrectomy and 1 underwent Roux-en-Y gastric bypass. The 3 patients were numbered as No.1, No.2, and No.3 according to the operation time. Observation indicators: (1) construction of three-dimensional digital model of small bowel and preoperative prediction of small bowel length; (2) intraoperative measurement of small bowel length and the relative error between preoperative prediction of small bowel length and intraoperative measurement of small bowel length. Count data were represented as absolute numbers or percentages.Results:(1) Construction of three-dimensional digital model of small bowel and preoperative prediction of small bowel length: the three-dimensional digital models of small bowel for each patient were constructed respectively before operation. The volume of small bowel, area of each cross-section for the 10 cross-sections of small bowel, average area of cross-section of small bowel, preoperative prediction of small bowel length in the three-dimensional digital model of small bowel of No.1 patient were 1 312 985 mm 3, 174 mm 2, 154 mm 2, 143 mm 2, 172 mm 2, 345 mm 2, 213 mm 2, 357 mm 2, 173 mm 2, 382 mm 2, 154 mm 2, 227 mm 2, 578 cm. The above indicators of No.2 patient were 1 817 224 mm 3, 274 mm 2, 196 mm 2, 487 mm 2, 413 mm 2, 520 mm 2, 254 mm 2, 231 mm 2, 170 mm 2, 212 mm 2, 168 mm 2, 293 mm 2, 620 cm. The above indicators of No.3 patient were 2 183 019 mm 3, 320 mm 2, 408 mm 2, 281 mm 2, 222 mm 2, 194 mm 2, 219 mm 2, 188 mm 2, 419 mm 2, 326 mm 2, 235 mm 2, 281 mm 2, 777 cm.

The relative error between preoperative prediction of small bowel length and intraoperative measurement of small bowel length of No.1, No.2, and No.3 patients were 1.40%、3.33%、0.38%, respectively. Conclusion:Three-dimensional digital model of the small bowel can predict the small bowel length before bariatric surgery.

OBJECTIVE: The purpose of this study was to assess the association between triglycerides (TG), total cholesterol (TC) at baseline, and type 2 diabetes mellitus (T2DM) incidence in a general Chinese population. Further, it aimed to evaluate the ability of TG and TC to predict T2DM incidence. METHODS: Qingdao Diabetes Prevention Program participants recruited between 2006 and 2009 were followed up in 2012-2015. TG, TC, and T2DM status were measured. Cox proportional hazards models were used to estimate the association between TG, TC, and T2DM incidence. The receiver operating characteristic (ROC) curve was used to evaluate the ability of TG and TC to identify T2DM participants. RESULTS: The incidence of T2DM significantly increased with TG in women and TC in both men and women (Ptrend < 0.05). Univariate Cox regression indicated that higher TG {borderline high TG [hazards ratio (HR): 2.05; 95% confidence interval (CI): 1.40, 3.00] and hypertriglyceridemia [HR: 2.64; 95% CI: 1.68, 4.15]} and TC [hypercholesterolemia (HR: 2.05; 95% CI: 1.43, 2.95)] were significantly associated with increased risk of T2DM incidence in women but not in men. Multivariate Cox regression showed that hypertriglyceridemia in women (HR: 1.78, 95% CI: 1.07, 2.97), borderline high TC in men (HR: 1.61, 95% CI: 1.04, 2.48), and hypercholesterolemia in women (HR: 1.68, 95% CI: 1.81, 2.61) had a higher significant risk of T2DM incidence. The optimal cutoff values of TG were > 1.15 and > 1.23 mmol/L in men and women, respectively. For TC, they were > 5.17 and > 5.77 mmol/L in men and women, respectively. The area under the ROCs of TG and TC were 0.54 (0.51-0.57) and 0.55 (0.52-0.58), respectively, in men, and 0.60 (0.58-0.62) and 0.59 (0.56-0.61), respectively, in women. CONCLUSION Elevated TG and TC were risk factors for T2DM incidence. However, no predictive capacity was found for both factors to identify T2DM incidence in Chinese men and women. Hence, TG and TC levels in both Chinese men and women might be used for decreasing the incidence of T2DM but no clinical predictive capacity for T2DM.
