Abstract
Objective: To investigate the present situation of pelvic floor muscle strength, and to analyze the factors affecting pelvic floor muscle strength. Methods: The data of patients who were admitted into the general outpatient department of gynecology, Peking University People's Hospital from October 2021 to April 2022 were collected, and the patients who met the exclusion criteria were included in this cross sectional study. The patient's age, height, weight, education level, defecation way and defecation time, birth history, maximum newborn birth weight, occupational physical activity, sedentary time, menopause, family history and disease history were recorded by questionnaire. Morphological indexes such as waist circumference, abdomen circumference and hip circumference were measured with tape measure. Handgrip strength level was measured with grip strength instrument. After performing routine gynecological examinations, the pelvic floor muscle strength was evaluated by palpation with modified Oxford grading scale (MOS). MOS grade>3 was taken as normal group and ≤3 as decreased group. Binary logistic regression was used to investigate the related factors of deceased pelvic floor muscle strength. Results: A total of 929 patients were included in the study, and the average MOS grade was 2.8±1.2. By univariate analysis, birth history, menopausal time, defecation time, handgrip strength level, waist circumference and abdominal circumference were related to the decrease of pelvic floor muscle strength (all P<0.05). By binary logistic regression analysis, the level of handgrip strength (OR=0.913, 95%CI: 0.883-0.945; P<0.001) was correlated with normal pelvic floor muscle strength; waist circumference (OR=1.025, 95%CI: 1.005-1.046; P=0.016), birth history (OR=2.224, 95%CI: 1.570-3.149; P<0.001), sedentary time> 8 hours (OR=2.073, 95%CI: 1.198-3.587; P=0.009) were associated with the decrease of pelvic floor muscle strength. Conclusions: The level of handgrip strength is related to the normal pelvic floor muscle strength of females, while the waist circumference, birth history and sedentary time>8 hours are related to the decrease of pelvic floor muscle strength of females. In order to prevent the decrease of pelvic floor muscle strength, it is necessary to carry out relevant health education, enhance exercise, improve the overall strength level, reduce daily sedentary time, maintain symmetry, and carry out comprehensive overall intervention to improve pelvic floor muscle function.

Abstract
OBJECTIVE To explore the clinical value of contrast-enhanced ultrasound (CEUS) in the differential diagnosis of benign and malignant subpleural pulmonary lesions (SPLs). METHODS Among 959 patients with SPLs who were scheduled to undergo ultrasound-guided puncture in our department between January 2019 and June 2019, 506 patients were included and their B-mode ultrasound and CEUS features, including the lesion's location, size, margin, echo, perfusion pattern of ultrasound contrast agent, degree of enhancement, homogeneity, vascular signs, and necrosis, were retrospectively investigated. All malignant cases were diagnosed by pathology, while benign cases were diagnosed by two respiratory physicians after comprehensive analysis of pathology, etiology, imaging, and clinical symptoms. Statistical differences in these features between the benign and malignant groups were then analyzed. RESULTS There were 506 cases in this study, including 219 benign cases and 287 malignant cases. Among them, 351 were males and 155 were females, with an average age of 59 ± 16 years. There were statistically significant differences between benign and malignant groups in the perfusion pattern, the degree of enhancement, and vascular signs. The features of the malignant group included local-to-whole perfusion pattern, hypo-enhancement, and curly hair sign, while those of the benign group included a centrifugal perfusion pattern, iso-enhancement and hyper-enhancement, and dendritic sign. There was no statistically significant difference between the two groups in homogeneity and necrosis. CONCLUSIONS CEUS enhancement mode is different between benign and malignant SPLs, which can provide supplementary information for the differential diagnosis of SPLs in the existing imaging diagnosis.

Abstract
Objective: This study aims to investigate the sleep quality of pregnant women in Xuhui District, Shanghai, and the related factors of sleep disturbances during pregnancy. Methods: From February 2019 to February 2021, we used online integrated sleep questionnaire (including PSQI, BQ, ESS, AIS) in Shanghai Jiao Tong University School of Medicine Affiliated Sixth People's Hospital, The International Peace Maternity and Child Health Hospitals of China Welfare Institution, and Shanghai Eighth People's Hospital, to investigate the sleep quality across pregnancy. We also collected maternal physical examination results, childbearing history, sociodemographic, and other clinical data. The prevalences and related factors of various sleep disturbances in pregnant women were analyzed, including insufficient/excessive nighttime sleep, low sleep efficiency, difficulty falling asleep, poor sleep quality, insomnia, daytime sleepiness, and high risk of sleep-disordered breathing (SDB). Results: This study includes 1 898 cases in the first trimester (T1), 3 099 cases in the second trimester (T2), and 1 539 cases in the third trimester (T3). Poor sleep quality (38.6%), daytime sleepiness (mild 41.9%, moderate 17.7%, severe 2.1%), and suspicious insomnia (32.3%) are most prevalent among women in T1 (P<0.01). In comparison, short sleep time (2.7%), long sleep time (8.6%), difficulty falling asleep (12.2%), poor sleep efficiency (35.4%), very poor sleep quality (6.7%), clinical insomnia (21.8%), and high-risk SDB (6.4%) are most prevalent among women in T3 (P<0.05). During pregnancy, late gestation (OR=1.016, 95%CI: 1.006-1.025) and multiple induced/drug abortions (OR=1.329, 95%CI: 1.043-1.692) are risk factors for poor sleep quality (PSQI>5), while multiple full-term deliveries (OR=0.800, 95%CI: 0.675-0.949) is its protective factor. Advanced maternal age (OR=0.976, 95%CI: 0.956-0.997), multiple full-term deliveries (OR=0.808, 95%CI: 0.680-0.959), late gestation (OR=0.983, 95%CI: 0.974-0.992) and hypertension (OR=0.572, 95%CI: 0.401-0.814) are protective factors for daytime sleepiness (ESS>6). The high-risk pregnancy category (OR=9.312, 95%CI: 1.156-74.978) is a risk factor for insomnia (AIS≥4), while multiple full-term deliveries (OR=0.815, 95%CI: 0.691-0.961) is its protective factor. High BMI (OR=1.334, 95%CI: 1.270-1.402) and hypertension (OR=4.427, 95%CI: 2.539-7.719) are risk factors for high-risk SDB in pregnant women. Conclusions: The prevalences of various sleep disturbances are high throughout pregnancy. Noticeably, symptoms of maternal SDB develop along with pregnancy. Different types of sleep disturbances are associated with different factors. Women of high-risk pregnancy category, in late gestation, with high BMI, hypertension, a history of induced/drug abortion, or without a history of full-term delivery can be at high risk of sleep disturbances during pregnancy.

Abstract
Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ2 test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

Abstract
Objective: To investigate the prevalence and associated risk factors of metabolic syndrome (MS) in patients with obstructive sleep apnea (OSA). Methods: From July 2007 to June 2017, a total of 8 155 adult subjects, including 6 484 males and 1 671 females, aged 18-90 (43.13±12.28), body mass index 14.61~59.56 (25.59±3.98) kg/m2,who were admitted to the Department of Otorhinolaryngology head and Neck surgery of The Sixth People's Hospital affiliated to Shanghai Jiao Tong University, were retrospectively analyzed. All patients underwent polysomnography and biochemical tests. Subjects were divided into four groups (non-OSA, mild OSA, moderate OSA, and severe OSA) according to OSA severity. The prevalence of MS was expressed as percentage, and the correlation between OSA and MS and its characteristic pathophysiological indicators was evaluated by logistic regression model after adjusting for factors such as gender, age, BMI, neck circumference, hip circumference, smoking and alcohol consumption, and was expressed by odds ratio (OR). SPSS 25.0 software was used for statistical analysis. Results: The overall prevalence of MS was 43.6%, and that of non-/mild/moderate/severe OSA group was 18.6%, 30.4%, 43.8%, 57.1%.Logistic regression showed that patients with mild/moderate/severe OSA had an increased risk of MS compared with non-OSA patients, with adjusted OR values and confidence intervals of 1.27 (1.05-1.54), 1.84 (1.53-2.22), and 2.08 (1.76-2.46), respectively (P<0.01).In addition, indicators of OSA anoxic burden [oxygen drop index(Toxygen=7.1), minimum blood oxygen(Tminimum=56.3), blood oxygen saturation below 90% cumulative time ratio (TCT90=10.6) ]were closely associated with MS disease(P<0.01), but sleep fragmentation index (arousals index) was not significantly associated with MS disease. Conclusion: The risk of MS gradually increases with the severity of OSA, and the indicators reflecting OSA hypoxia burden are closely related to MS disease.

Abstract
The establishment of polarity is an essential process in early neuronal development. Cdc42, a GTPase of the Rho family, is a key regulator of cytoskeletal dynamics and neuronal polarity. However, the mechanisms underlying the action of cdc42 in regulating axonogenesis have not been elucidated. Here, we expressed wild-type cdc42, a constitutively active cdc42 mutant (cdc42F28L) and a dominant negative cdc42 mutant (cdc42N17), respectively, in the primary hippocampal neurons to alter the activity of cdc42. We found that cdc42 activities were paralleled with the capacities to promote axonogenesis in the cultured neurons. Cdc42 also enhanced microtubule stability in the cultured neurons. Pharmacologically stabilizing microtubules significantly abrogated the defective axonogenesis induced by cdc42 inhibition. Moreover, cdc42 promoted the dephosphorylation of collapsing response mediator protein-2 (CRMP-2) at Thr514 by increasing GSK-3β phosphorylation at Ser9 in the cultured neurons. These findings suggest that cdc42 may facilitate axonogenesis by promoting microtubule stabilization in rat primary hippocampal neurons.

Abstract
Background US has proven valuable in the diagnosis of subpleural pulmonary lesions (SPLs); however, existing US indicators have limitations. Purpose To propose and validate a revised contrast-enhanced (CE) US indicator for differential diagnosis of benign and malignant SPLs and to compare its performance with existing CE US diagnostic criteria. Materials and Methods This prospective study (Chinese clinical trial registry, ChiCTR1800019828) enrolled patients with SPLs between May 2019 and August 2020. They were divided into a developmental cohort (DC) and a validation cohort (VC). In the DC, the optimal indicator was selected from five CE US indicators. In the VC, the selected indicator was compared with existing CE US diagnostic criteria using the area under the receiver operating characteristic curve (AUC). Pathologic analysis, microbial evidence, and clinical follow-up were used as reference standards for all SPLs. Results A total of 902 participants (DC, 424 participants; VC, 478 participants) with SPLs (mean age, 56 years ± 17; 593 men) were evaluated. The arrival time (AT) difference ratio proved to be the optimal indicator to distinguish benign from malignant SPLs. In the overall (regardless of lesion size), large (vertical diameter >3 cm), and small (vertical diameter ≤3 cm) lesion groups, the cutoff values of the AT difference ratio were 43%, 42%, and 50% and the AUCs obtained from the VC were 0.91 (95% CI: 0.88, 0.93), 0.97 (95% CI: 0.94, 0.98), and 0.77 (95% CI: 0.71, 0.83) respectively, which were higher than those of lesion-lung AT difference greater than 2.5 seconds (0.81 [P < .001], 0.85 [P < .001], and 0.7 [P = .005], respectively), lesion AT greater than 7.5 seconds (0.65 [P < .001], 0.64 [P < .001], and 0.63 [P < .001], respectively), and lesion AT greater than 10 seconds (0.67 [P < .001], 0.68 [P < .001], and 0.64 [P < .001] respectively). Conclusion The US contrast agent arrival time difference ratio enables better differentiation of benign and malignant subpleural lesions when compared with existing diagnostic criteria.

Abstract
SARS-CoV-2 infection causes a wide spectrum of clinical manifestations in humans, and olfactory dysfunction is one of the most predictive and common symptoms in COVID-19 patients. However, the underlying mechanism by which SARS-CoV-2 infection leads to olfactory disorders remains elusive. Herein, we demonstrate that intranasal inoculation with SARS-CoV-2 induces robust viral replication in the olfactory epithelium (OE), not the olfactory bulb (OB), resulting in transient olfactory dysfunction in humanized ACE2 (hACE2) mice. The sustentacular cells and Bowman’s gland cells in the OE were identified as the major target cells of SARS-CoV-2 before invasion into olfactory sensory neurons (OSNs). Remarkably, SARS-CoV-2 infection triggers massive cell death and immune cell infiltration and directly impairs the uniformity of the OE structure. Combined transcriptomic and quantitative proteomic analyses revealed the induction of antiviral and inflammatory responses, as well as the downregulation of olfactory receptor (OR) genes in the OE from the infected animals. Overall, our mouse model recapitulates olfactory dysfunction in COVID-19 patients and provides critical clues for understanding the physiological basis for extrapulmonary manifestations of COVID-19.

Abstract
Objective To develop and prospective validate an ultrasound (US) prediction model to differentiate between benign and malignant subpleural pulmonary lesions (SPLs). Methods This study was conducted retrospectively from July 2017 to December 2018 (development cohort [DC], n = 592) and prospectively from January to April 2019 (validation cohort [VC], n = 220). A total of 18 parameters of B-mode US and contrast-enhanced US (CEUS) were acquired. Based on the DC, a model was developed using binary logistic regression. Then its discrimination and calibration were verified internally in the DC and externally in the VC, and its diagnostic performance was compared with those of the existing US diagnostic criteria in the two cohorts. The reference criteria were from the comprehensive diagnosis of clinical-radiological-pathological made by two senior respiratory physicians. Results The model was eventually constructed with 6 parameters: the angle between lesion border and thoracic wall, basic intensity, lung-lesion arrival time difference, ratio of arrival time difference, vascular sign, and non-enhancing region type. In both internal and external validation, the model provided excellent discrimination of benign and malignant SPLs (C-statistic: 0.974 and 0.980 respectively), which is higher than that of “lesion-lung AT difference ≥ 2.5 s” (C-statistic: 0.842 and 0.777 respectively, P <0.001) and “AT ≥ 10 s” (C-statistic: 0.688 and 0.641 respectively, P <0.001) and the calibration curves of the model showed good agreement between actual and predictive malignancy probabilities. As for the diagnosis performance, the sensitivity and specificity of the model [sensitivity: 94.82% (DC) and 92.86% (VC); specificity: 92.42% (DC) and 92.59% (VC)] were higher than those of “lesion-lung AT difference ≥ 2.5 s” [sensitivity: 88.11% (DC) and 80.36% (VC); specificity: 80.30% (DC) and 75.00% (VC)] and “AT ≥ 10 s” [sensitivity: 64.94% (DC) and 61.61% (VC); specificity: 72.73% (DC) and 66.67% (VC)]. Conclusion The prediction model integrating multiple parameters of B-mode US and CEUS can accurately predict the malignancy probability, so as to effectively differentiate between benign and malignant SPLs, and has better diagnostic performance than the existing US diagnostic criteria.

Abstract
We aimed to explore the value of contrast-enhanced ultrasound (CEUS) of the pleural cavity in locating catheters and identifying fibrous septa and to compare CEUS with multiple existing methods. We included 304 participants whose pleural effusion could not continue to be drained and compared the catheter-localization capabilities of empirical diagnosis, B-mode ultrasound with normal saline and CEUS, with computed tomography as the reference standard. CEUS performed the best (accuracy, 100%; sensitivity, 100%; specificity, 100%), followed by B-mode ultrasound with normal saline (accuracy, 77.78%; sensitivity, 62.5%; specificity, 100%), and finally empirical diagnosis (accuracy, 54.17%; sensitivity, 66.67%; specificity, 33.33%). The capabilities of CEUS and computed tomography to identify fibrous septa were evaluated, with B-mode ultrasound as the reference, and CEUS (accuracy, 100%; sensitivity, 100%; specificity, 100%) was superior to computed tomography (accuracy, 82.41%; sensitivity, 26.09%; specificity, 97.65%). Overall, CEUS can accurately locate catheters and identify fibrous septa, with performance superior to existing methods.

Abstract
BACKGROUND Cell-free DNA (cf-DNA)-based liquid biopsy is emerging as a revolutionary new method in individualized cancer treatment and prognosis monitoring, although detecting early-stage cancers using cf-DNA remains challenging, partially because of the undefined biological background of cf-DNA. MATERIALS AND METHODS We investigated somatic mutations in the cf-DNA of 259 cancer-free individuals with a median age of 47 years using an endogenous barcoding duplex method with an ultralow base error rate (2 × 10-7) and compared the variant allele frequencies (VAFs) of these mutations between the cf-DNA and the corresponding blood cell DNA. RESULTS Sixty percent (155/259) of the samples showed at least one nonsynonymous mutation on either of two similar target panels covering 508 and 559 cancer-related genes. For individuals older than 50 years of age, the positive rate increased to 76%. Most cf-DNA mutations were also present at similar VAFs in the paired blood cell DNA. The most frequently mutated genes were driver genes of hematologic malignancies, including DNMT3A, TET2, AXSL1, and JAK2. However, the other 58.4% (192/329) of the mutations were likely 'passenger mutations' of clonal hematopoiesis, including mutations in NOTCH2, FAT3, EXT2, ERBB4, and ARID2, which are driver genes of solid tumors. CONCLUSION Hematopoietic clone-derived mutations, including 'driver mutations' and 'passenger mutations', are prevalent in the cf-DNA of both healthy individuals and cancer patients and may be a potential source of false positives in the liquid biopsy. Our results also suggest the ineffectiveness for distinguishing clonal hematopoietic mutations of low VAF (≤0.1%) from tumor-derived mutations using conventional next-generation sequencing of blood cell DNA. However, an error correction model with an ultralow error rate and high coverage depth is required for blood cell DNA sequencing, which is difficult and costly to achieve with current technologies.

Abstract
Objective:To explore the relationship between smoking and the severity of OSA. Method:There were 719 patients included in the study, who were accompanied by snoring, daytime sleepiness and other symptoms. Laboratory-based polysomnographic variables (including AHI, oxygen desaturation index and microarousal index, etc.), and anthropometric measurements (including weight, neck circumference, waist circumference, hip circumference etc.) were collected for all participants. The severity of OSA was determined by AHI. No OSA was defined as AHI<5, mild OSA as AHI of 5 to 15,moderate OSA as AHI of >15 to 30, and severe OSA as AHI of >30. Smoking severity was determined by the smoking index (SI). Light smoke was defined as SI<200, moderate smoke was as SI 200 to 400, and severe smoke as SI>400. Result:There were 138 cases of non-OSA and 581 cases of OSA. There were 381 non-smokers, 279 smokers and 59 quit smokers. The smoking rate of OSA group was significantly higher than that of non-OSA group (41.5% vs. 27.5%,P<0.01). After excluding 59 quit smokers, the remaining 660 subjects were divided into four groups according to the severity of smoking, then each group was further divided into four groups according to OSA severity. Unadjusted analysis showed that OSA severity positively correlated with smoking severity (r=0.203,P<0.01). The positive correlation remained significant after further adjustment for age, BMI and waist-hip ratio. In addition, logistic regression analysis showed that compared to non-smokers, the odd ratios for OSA in moderate smokers were 1.72 (95%CI 1.08-2.75) and in severe smokers were 2.68 (95%CI 1.61-4.46), after adjustment for age, BMI and waist-hip ratio. Conclusion:The severity of smoking significantly correlated with the severity of OSA. There was increased risk of OSA in patients with severe smoke. The correlation was independent of some confounders such as age and obesity.

Abstract
BACKGROUND The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87% in the ENOTES group, which was statistically different from 78.12% in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

Abstract
OBJECTIVE To investigate the protective effect of Qihuang Mingmu capsule (QHMM) on retina of diabetic mice and its impact on VEGF expression. METHOD Forty KK/Upj-Ay mice were randomly divided into the model group and high, middle and low dose QHMM (8.32, 4.16, 2.08 g x kg(-1)) groups. Additional 10 C57BL/6 mice were selected as the control group. Mice were orally administered for three months. Their general appearance, fasting blood-glucose (FBG) and glycosylated hemoglobin (HbA1c) were observed. Pathological changes of retina were observed by light microscope and electron microscope. The expressions of vascular endothelial growth factor (VEGF), growth factor receptors-1 (Flt-1) and growth factor receptors-2 (Flk-1) were examined by Real-time PCR (qPCR) and Western blot. RESULT QHMM could ameliorate the symptoms of diabetic mice to varying degrees, decrease FBG and HbA1c, alleviate pathological lesions of retina and decrease the expressions of VEGF, Flt-1, Flk-1 mRNA and protein. CONCLUSION QHMM has the protective effect on diabetic retinopathy of mice by inhibiting the expressions of VEGF, Flt-1 and Flk-1 and intervening VEGF-VEGFR signal transduction pathway.

Abstract
AIM: To assess the value of linear endoscopic ultrasonography (EUS) in the diagnosis of rectal endometriosis (RE).
METHODS: Twenty patients with endometriosis were referred for linear EUS prior to the surgical intervention to evaluate the rectal involvement. RE was diagnosed by the presence of a hypoechoic nodule or mass with irregular margins in the rectal wall. Linear EUS findings were compared with the results of surgical exploration and histopathologic examination.
RESULTS: Linear EUS allowed to detect endometriotic lesions in the rectal wall in 12 cases, and the rectal wall was considered normal in 8 cases. In RE cases diagnosed by linear EUS, surgical exploration showed that pelvic ectopic endometrial lesions adhered closely to the rectal wall, and the histopathologic results confirmed infiltration of the rectal wall by endometriotic lesions. For the 8 patients with no linear EUS evidence of rectal infiltration, there was mild adhesion or no adhesion between pelvic ectopic endometrial lesions and the rectal wall, and histopathologic examination showed that the rectum was not involved by endometriotic lesions. The findings of linear EUS were coincident with those of surgical exploration and histopathologic examination.
CONCLUSION: Linear EUS is a reliable method for diagnosis of rectal endometriosis and can be used for accurate pre-surgical assessment of the rectal involvement in patients with endometriosis.

Abstract
UNLABELLED This multicenter and randomized clinical trial showed that daily oral herbal formula Xian Ling Gu Bao (XLGB) was safe in postmenopausal women over a 1-year treatment. Those patients (n ∼ 50) treated with XLGB at the conventional dose demonstrated a statistically significant increase in dual-energy X-ray absorptiometry (DXA) bone mineral density (BMD) at lumbar spine at 6 months and a numerically increased BMD at 12 months. INTRODUCTION The aim of this study was to examine the safety and efficacy of a herbal formula XLGB in postmenopausal women (ChiCTR-TRC-00000347). METHODS One hundred eighty healthy postmenopausal women (≥60 years old) with BMD T-score ≤ -2.0 (lumbar spine or femoral neck) were recruited from four clinical centers to receive low-dose (conventional dose) XLGB (L-XLGB group, 3 g/day, n = 61) or high-dose XLGB (H-XLGB group, 6 g/day, n = 58) or placebo (CON group, n = 61). Women received daily calcium (500 mg) and vitamin D (200 IU) supplementation. Primary endpoints were lumbar spine BMD and safety; secondary endpoints were femoral neck BMD and bone turnover markers measured at baseline and at 6 and 12 months. RESULTS Of 180 women recruited, 148 completed the study. The compliance in each group was comparable. Prominent adverse events were not observed in either group. In the L-XLGB group at 6 months, lumbar spine BMD by DXA increased significantly from baseline (+2.11% versus CON +0.58%, p < 0.05), but femoral neck BMD did not; at 12 months, BMD in the L-XLGB group decreased from 6-month levels yet remained higher than baseline, but without difference from the CON group. There was no dose-dependent response. Bone turnover marker levels declined during the first 6 months after XLGB treatment. There was no significant difference in the overall incidence of side effects among treatment and control groups. CONCLUSION XLGB over 1-year treatment at the conventional dose demonstrated safe and only a statistically significant increase in BMD at lumbar spine at 6 months in postmenopausal women.

Abstract
AIM: To establish a big animal model of obesity and type 2 diabetes for further investigation of surgical or endoscopic interventional therapy of this disease.
METHODS: Ten healthy adult male Beagle dogs were randomly and equally divided into two groups: control group and model group. The control group was feed a standard diet during the whole experiment (16 wk), while the model group was feed a high-fat hypercaloric diet. At week 8, the model group was intravenously injected with small dose of streptozotocin (STZ). The body mass, length, fasting blood glucose, intravenous glucose tolerance test (IVGTT), and lipid were measured regularly.
RESULTS: At week 8, the average body mass (16.9 kg ± 0.8 kg vs 14.8 kg ± 1.03 kg, P < 0.01), Lee index (P < 0.05), serum insulin and c-peptide (both P < 0.01) were significantly higher in the model group than in the control group. One week after STZ injection, in the model group, the fast blood glucose was significantly higher than that in the control group (P < 0.05), IVGTT-2 h glucose was significantly higher than the pre-injection value (143 mg/dL ± 7.4 mg/dL vs 127 mg/dL ± 4.2 mg/dL, P < 0.05), and serum insulin and c-peptide decreased significantly (P < 0.01). Eight weeks after STZ injection, in the model group, the fast blood glucose was significantly higher than that in the control group (P < 0.01), and IVGTT-2h glucose was significantly higher than the pre-injection value (323 mg/dL ± 12.1 mg/dL vs 127 mg/dL ± 4.2 mg/dL, P < 0.01). All Beagle dogs were confirmed to have type 2 diabetes, and no Beagle dogs died during the experimental period.
CONCLUSION: A high-fat hypercaloric diet combined with intravenous injection of small dose of STZ can induce obesity and type 2 diabetes in Beagle dogs. This animal model mimics the nature history and metabolic characteristics of human type 2 diabetes and can be used for further investigation of surgical or endoscopic interventional therapy of obesity and type 2 diabetes.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) the etiology of which has not yet been fully clarified. Cytokine interleukin-10 (IL-10) plays a central role in downregulating inflammatory cascade in UC and is likely a candidate for therapeutic intervention. However, its intravenous administration is costly and inconvenient. Therefore, we established a novel IL-10 delivery system by transforming a hIL-10-containing plasmid into B. longum (BL-hIL-10) and investigated its effects on 5% dextran sulfate sodium (DSS)-induced ulcerative colitis in mice and the possible underlying mechanism. Our results show that (1) hIL-10 was expressed and secreted into the culture supernatant of BL-hIL-10 after L-arabinose induction in vitro as examined by Western blot, enzyme-linked immunosorbent assay (ELISA) and RT-PCR; (2) addition of BL-hIL-10 culture supernatant had no cytotoxic effect and morphological alteration, but significantly inhibited the enhancement of proinflammatory cytokines by lipopolysaccharide (LPS) in THP-1 cells; (3) oral administration of BL-hIL-10 alleviated colitis syndrome of the model mice, attenuated colitis-activated NF-κB pathway measured by DNA-binding assay and colitis-elevated expression of proinflammatory cytokines examined with CCK cytotoxic kits, and upregulated CD4+CD25+Foxp3+ Treg in blood and mesenteric lymph nodes measured by flow cytometry. In conclusion, BL-hIL-10 as a novel oral hIL-10 delivery system has been successfully established and oral administration of BL-hIL-10 alleviated inflammatory damage of colonic tissue in the model mice by blocking the colitis-activated NF-κB pathway and upregulating CD4+CD25+Foxp3+ Treg in blood and mesenteric lymph nodes in mice.

Abstract
Along with social progress and life style transformation, morbid obesity, type 2 diabetes mellitus, and metabolic syndrome are increasingly becoming a great threat to human health. Because conventional conservative treatment has little effect on these diseases, they were considered incurable before. However, surgery shows good results in the treatment of these diseases and has therefore revolutionized their treatment. This review aims to elucidate the therapeutic mechanisms of surgery for morbid obesity and 2 diabetes mellitus and to discuss the current situation and future prospects of surgical treatment of these diseases.

Abstract
The complex reactions of typical medical waste materials pyrolysis and the evolution of different volatile species can be well represented by a Distributed Activation Energy Model (DAEM). In this study, A thermogravimetric analyser (TGA), coupled with Fourier transform infrared analysis of evolving products (TG-FTIR), were used to perform kinetic analysis of typical medical waste materials pyrolysis. A simple direct search method was used for the determination of DAEM kinetic parameters and the yield of individual pyrolysis products under any given heating condition. The agreement between the model prediction and the experimental data was generally good. The results can be used as inputs to a pyrolysis model based on first-order kinetic expression with a Gaussian Distribution of Activation Energies as a sub-model to CFD code.

Abstract
AIM: To construct eukaryotic expression plasmids containing short hairpin RNA (shRNA) that target at the myeloid cell leukemia-1 (mcl-1) gene, and to select the plasmids that silence mcl-1 gene most efficiently.
METHODS: Three pairs of shRNAs that target at mcl-1 gene were designed. The eukaryotic expression plasmids (named shRNA1-3) were constructed and identified using restriction enzyme analysis and sequencing analysis. The plasmids were then transfected into HepG2 cells via liposome. The transfection rate of recombinant plasmids was measured 48 h after transfection, and mcl-1 mRNA and protein expression was determined using reverse transcriptase-polymerase chain reaction and Western blotting.
RESULTS: The expression plasmids were confirmed by restriction enzyme analysis and sequencing analysis. The transfection rate of recombinant plasmids in HepG2 cells was approximately 64%. Forty-eight hours after transfection, the mcl-1 mRNA and protein levels of shRNA1-3 group (mRNA: 0.61 ± 0.02, 0.56 ± 0.02 and 0.46 ± 0.01, protein: 0.53 ± 0.01, 0.48 ± 0.03 and 0.36 ± 0.01, respectively) were significantly lower than that of the blank control group (mRNA: 0.61 ± 0.02, 0.56 ± 0.02, 0.46 ± 0.01 vs 0.97 ± 0.01; protein: 0.53 ± 0.01, 0.48 ± 0.03, 0.36 ± 0.01 vs 0.90 ± 0.03, all P < 0.01) and that of the negative control group (mRNA: 0.95 ± 0.00, protein: 0.88 ± 0.01, all P < 0.01). Compared with shRNA1 and shRNA2, shRNA3 had the strongest inhibitory effect on mRNA (52.6% vs 36.3%, 42.9% both P < 0.01) and protein level of Mcl-1 (63.2% vs 41.5%, 49.6%, both P < 0.01).
CONCLUSION: The shRNA eukaryotic expression plasmid targeting at mcl-1 gene is constructed and selected successfully. The mcl-1 mRNA and protein expression was suppressed significantly by this given plasmid.

Abstract
Pyrolysis of certain medical waste materials was studied using thermogravimetric analyzer coupled with Fourier transform infrared spectroscopy (TG-FTIR). Pyrolysis characteristics of three common materials were discussed. The pyrolysis of absorbent cotton turned out to be the most concentrative, followed by medical respirator and bamboo stick. From TG and DTG curves, pyrolysis of these three materials occurred in single, two and three stages respectively. Evolved volatile products from all these three materials included 2-butanone, benzaldehyde, formic acid, acetic acid, hydrocarbon, carbon dioxide, carbon monoxide, and water; whereas no sulphur dioxide, ammonia and hydrogen cyanide was detected. There are several differences in yield among them. However, the study in this paper is essential for medical waste pyrolysis model, the TG-FTIR approach is potential to provide valuable inputs for predictive modeling of medical waste pyrolysis. More studied are needed to get the kinetic parameters and pyrolysis models that can predict yields and evolution patterns of selected volatile products for CFD applications.

Abstract
The complex structures of Human Immunodeficiency Virus Type 1 (HIV-1) integrase binding two highly potent and nontoxic inhibitors, lithospermic acid (M/sub 5/22) and lithospermic acid B (M/sub 5/32), were obtained using docking calculations. Docking results provided detailed information of their binding modes. The binding sites of M/sub 5/22 and M/sub 5/32 were similar to the inhibitor 5-CITEP. The lowest docking energies for HIV-1 integrase binding M/sub 5/22 and M/sub 5/32 are in agreement with their corresponding lower IC/sub 50/ values. Our results on the chemical structure difference between M/sub 5/22 and M/sub 5/32 show that the carboxyl and hydroxyl groups on the side-chain of M/sub 5/32 are important chemical groups which could help to increase the effect against HIV-1 IN replication.

The ODNs were annealed to the corresponding mRNA molecules and they were added to rabbit reticulocyte cell-free system. The translation products were analyzed by SDS-PAGE. After fixing, the gel was exposed to X-ray film by autoradiography for analysis of protein synthesis. RESULTS Six mumol/L of ODNs elicited a 50% reduction in specific protein expression, and 20 mumol/L of ODNs inhibited the expression of esterase by 80%. The SDS-PAGE showed that the band of reduced amounts of 65 kDa protein for resistant mosquito was almost the same as that for sensitive sample. CONCLUSION Antisense oligonucleic acids to the esterase mRNA of dipterex-resistant mosquito could effectively inhibit its in vitro translation.

Abstract
AIM: To compare the features of gastroesophageal reflux disease between elderly and younger patients.
METHODS: Twenty-four hour pH-monitoring and endoscopy were per formed for the 66 elderly patients with typical gastroesophageal reflux symptoms, and the results were compared with 112 symptomatic younger patients.
RESULTS: The results of 24-h pH-monitoring and endoscopy showe d that the elderly patients had pathological reflux and reflux esophagitis more frequently than the younger patients. Percentage time with pH < 4 in elderly patients with reflux esophagitis was 32.5% in 24 h, as compared with 12.9% in the younger patients with reflux esophagitis (P < 0.05). The elderly patients with reflux esophagitis have longer periods of acid reflux in both upright and supine positions than the younger patients. Endoscopy showed that 20.8% of elderly patients had grade III/IV esophagitis, whereas only 3.4% of younger patients had grade III/IV esophagitis (P < 0.002). Percentages of grades I/II esophagitis in the two groups were 12.5% and 26.5%, respectively (P < 0.002).
CONCLUSION: Elderly patients, as compared with younger patients, have more severe gastroesophageal reflux and esophageal lesions. The incompetence of lower esophageal sphincter and the presence of hiatal hernia may be important factors leading to the difference in incidence and severity of reflux esophagitis between elderly and younger patients.

Abstract
AIM: To assess the relationship between gastric acid output (GAO) and both pattern of gastroesophageal reflux (GER) and esophageal lesions, and to evaluate the role of GAO and other potential pathogenetic factors in the development of esophagitis.
METHODS: Gastric acid secretory testing and 24-h intraesophageal pH monitoring were performed in 31 patients with esophagitis and concomitant duodenal ulcer (E + DU) and compared with those of 72 patients with esophagitis (E) alone.
RESULTS: The GAO in patients with E + DU was significantly higher than in patients with E (P < 0.05). There was no significant difference between the two groups of patients as to endoscopicl findings and parameters of GER (P > 0.05). A multiple regression analysis with stepwise deletion showed that the presence of hiatal hernia (HH), GER in upright position and age appeared to correlate significantly with the presence of esophagitis.
CONCLUSIONS: No parallel relationship between GAO and severity of GER or esophageal lesions exists in patients with E + DU, and that GAO is not a major pathogenetic factor in GER disease.

Abstract
AIM: To explore whether the presence of a sliding hiatus hernia influences gastroesophageal reflux.
METHODS: Endoscopy and 24 h pH monitoring were performed for 197 outpatients with gastroesophageal reflux symptoms.
RESULTS: Of the 197 patients with symptoms of gastroesophageal reflux, patients with hiatus hernia accounted for 36%. The incidence of esophagitis in patients with hiatus hernia was significantly higher than that in patients without hiatus hernia. The results of 24 h pH monitoring showed that 84 patients had physiological reflux, 37 had pathological reflux without esophagitis, 64 had reflux esophagitis and 12 had physiological reflux concomitant with esophagitis. All the patients with hiatus hernia had a longer percentage time with supine reflux and a higher frequency of episodes lasting over 5 min at night compared to those without hiatus hernia. The incidence of combined daytime and nocturnal reflux in patients with hiatus hernia was significantly higher than that in patients without hiatus hernia.
CONCLUSION: Pathological reflux and reflux esophagitis in some patients with symptoms of gastroesophageal reflux represent two different stages of gastroesophageal reflux disease. Pathological reflux is the first stage, in which the lower esophageal sphincter is incompetent but the esophageal mucosal resistance effectively prevents regurgitated acid from damaging the esophageal mucosa. Reflux esophagitis represents the second stage, in which the aggression of the regurgitated acid is so strong that the esophageal mucosa fails to resist it and the epithelium of the esophagus is damaged. Patients with hiatus hernia have a high incidence of combined daytime and nocturnal reflux, with the latter being responsible for esophagitis.

Abstract
One hundred and sixty centenarians were discovered and followed up for 7 years (1982-88) in Shanghai. The proportion of centenarians in the population was non-significantly greater in the urban than in the rural area and centenarians were in general increasing in both areas over the years. The factors promoting longevity were good medical care and benevolent attention from family members. Autopsy was performed in eight centenarians revealing the main causes of death as pneumonia and cancer.

Abstract
A five-year-old boy with psychomotor retardation, microcephaly, bilateral cataracts, hearing impairment and hypospadia with microphallus was found to have multiple cell lines from peripheral blood: 46,XY/46,XY, -13,+r(13)/46, Xy, -13, +dic r(13) in the ratio of 35%/61%/4% by trypsin-Giemsa, and C-bandings. Using fluorescence in situ hybridization (FISH) with biotin-labeled alpha-satellite probe (D21Z1/D13Z1) and fluorescence staining (FITC), we confirmed that the ring originated from chromosome 13. To elucidate changes in the chromosome ends in the ring originated from chromosome 13. To elucidate changes in the chromosome ends in the ring formation, we used human telomere-specific probes for FISH study; it showed an absence of telomeres on the ring chromosome, although Ag-NOR staining was positive. These findings yielded different breaking points on the ends of both the short and long arms of chromosome 13 from those reported in the literature.

Abstract
Twelve patients with rectal carcinoma were treated by intratumor BCG injection concurrently with drugs which antagonize Ts cells, inactivate suppressor macrophages and depress PGE-2 production. Remarkable results were obtained with mild side effects. Four patients achieved complete response and 8 partial response. There was a significant difference (P less than 0.005) between combined treatment and intratumor BCG injection alone. The local reactions of BCG injection, their relation to therapeutic effects and pathology are discussed. The observation of single, degenerated cancer cell encapsulated by epithelioid cells is an evidence that the cancer cell is directly killed by mononuclear cells.
