Abstract
PURPOSE To compare the effectiveness, safety and cost-effectiveness of endoscopic submucosal dissection (ESD) with transanal endoscopic microsurgery (TEM) in early rectal neuroendocrine tumor (RNET) patients. This article will provide reliable evidence for surgeons in regards to clinical decision-making. METHODS Systematic literature retrieval was performed in Pubmed, Embase and Cochrane database from 2013/4/30 to 2023/4/30. Methodology validation was performed by using the Newcastle-Ottawa Scale (NOS). Data-analysis was conducted by using the Review manager version 5.3 software. RESULTS A total of three retrospective studies were included in our meta-analysis. All eligible studies were considered to be high quality. By comparing baseline characteristics between TEM and ESD, patients in the TEM group seemed to be characterized by a larger tumor size and lower tumor level, even though no statistical significance was found. Clear statistical significance favoring TEM was identified in terms of R0 resection rate, procedure time and hospital stay. No statistical significance was found in terms of recurrence rate, adverse events rate and additional treatment rate. CONCLUSIONS Compared with ESD, TEM was a more effective treatment modality for early RNET patients; it was associated with a relatively higher R0 resection rate and a similar degree of safety. However, the relatively higher cost and complicated manipulation restricted the promotion of TEM. Surgeons should opt for TEM as a primary treatment in patients with a larger tumor size and deeper degree of tumorous infiltration if the financial condition and hospital facility permit.

Abstract
Objective: To investigate the clinical and pathological features of salivary secretory carcinoma (SSC). Methods: Ten cases of SSC confirmed in the Department of Pathology,Capital Medical University School of Stomatology from January 2014 to December 2021 were retrospectively included, including 5 males and 5 females, with a median age of 46.5 years. The microscopic morphology, immunophenotype, special staining and clinical follow-up of 10 cases of salivary secretory carcinoma were observed. Ten patients were tested with S-100, vimentin, mammaglobin, Dog-1, p63 and Ki-67, 9 cases with cytokeratin (CK) 8/18, 8 with CK7, 6 with calponin, 5 with smooth muscle actin (SMA) and GCDFP15, 4 with CK5/6 and 1 with SOX10. The ETV6-NTRK3 fusion gene was detected by fluorescence in situ hybridization. Results: Seven of the 10 SSC were located in the parotid gland and 3 were located in the cheeks. Histomorphology showed solid, papillary-cystic, follicular, microcystic, and macrocystic types. In 7 cases, tumor cells were dominated by single arrangement type, while certain mixed arrangements existed in some areas. The cytoplasm of the tumor cells was rich in eosinophilic, fine granular or vacuolar shapes, and clear cytoplasm was seen in 2 cases. The nuclei were mostly oval-shaped vesicular nuclei, with nucleoli in the center. Immunohistochemistry showed CK7 (8/8) positive, CK8/18 (9/9) positive, S-100 (10/10) positive, vimentin (5/10) positive, (4/10) partially positive and (1/10) less partially positive, mammaglobin (7/10) positive, (1/10) partially positive and (2/10) some individual cells positive, Dog-1 (10/10) negative, CK5/6 (4/4) negative, p63 (7/10) negative and (3/10) partially positive, SMA (5/5) negative, calponin (6/6) negative, and Ki-67 index was 5%-20%. Secretions of 5 cases showed periodic acid-Schiff (PAS) and PAS with diastase (PAS-D) staining positive. All 10 cases showed ETV6-NTRK3 fusion positive. Six cases were successfully followed up for 32-91 months, of which 2 cases recurred after 28 and 74 months and underwent surgical resection again. All cases followed up are alive and disease-free. Conclusions: The salivary secretory carcinoma is a rare low-grade malignant tumor. In certain cases, morphology is atypical and mammaglobin is immunohistochemically positive in only individual tumor cells. Therefore, the diagnosis should be supported with morphology, immunohistochemical staining, and molecular feature preferably.

Abstract
Post-stroke fatigue (PSF) is a common symptom after stroke and interferes with the rehabilitation. There are limited pharmacological therapies for managing PSF. Astragalus membranaceus (Huangqi) is a frequently used Chinese herbal medicine (CHM) in the treatment of fatigue in China. The aim of this review was to summarize the efficacy of adjuvant therapy with CHM Huangqi (CHM-HQ) in managing fatigue after stroke. We searched the databases in both English and Chinese for randomized controlled trials (RCTs) on CHM-HQ for PSF till November 2016. The Cochrane risk of bias tool was used to assess the quality of included trials, and the Review Manager 5.3 software was used to conduct the data analysis. Sixteen RCTs with a total of 1222 participants were included. The evidence was poor in quality with unclear or high risks of bias. Compared to routine intervention, treatment with CHM-HQ decreased the fatigue severity based on the assessment of the Fatigue Severity Scale, Fugl-Meyer and Visual Analogue Scale, and improved the quality of life as measured by the Stroke Specific Quality of Life scale, the Barthel index, and the modified Barthel index, while the adverse effects were mild. In conclusions, adjuvant therapy with CHM-HQ may benefit in managing fatigue and quality of life in stroke patients. However, stronger evidence is needed for a promising conclusion and more rigorous designs of RCTs are merited in the future.

Abstract
Background: Laparoscopic sleeve gastrectomy (LSG) has become the current mainstream surgical treatment for obesity. With the development of clinical practice, surgeons realized the associated severity and danger of postoperative bleeding and leakage. Surgeons constantly explore different strategies to reduce the incidence of these complications. By reviewing previous clinical articles on the staple line reinforcement (SLR) in LSG, the conclusions were inconsistent regarding effectiveness. This article aims to discuss effectiveness of oversewing the staple line in LSG. Methods: From the start date of each database to September 27, 2018, a comprehensive search of published articles in English was conducted in PubMed, Embase, Central (Cochrane) databases and Scopus databases. We extracted and analyzed the main results on postoperative bleeding, staple line leakage, hospital stay and operative time of the final included articles. This review was compliant with PRISMA guidelines. Results: Finally, we extracted and analyzed 11 randomized controlled trials (RCTs) which contain 2411 patients (1219 patients as part of the oversewing (OS) group and 1192 patients in the no-oversewing (NOS) group). In the OS group, there were 15 cases (1.23%) of postoperative bleeding, and 8 cases (0.66%) of postoperative leakage. While in the NOS group, 35 patients (2.94%) had postoperative bleeding and 21 patients (1.76%) had postoperative leakage. By comparing and analyzing the OS group and the NOS group, the risk ratio (RR) for postoperative bleeding was 0.48 (95% confidence interval [CI], 0.27-0.83 p = 0.447). In addition, the RR for postoperative leakage was 0.44 (95% CI, 0.21-0.89 p = 0.835). The standardized mean difference (SMD) for hospital stay was -0.10 (95% CI, -0.25 to 0.04 p = 0.061) and 2.26 for operative time (95%CI, 0.82-3.69 p = 0.000). Conclusion: This study suggested that oversewing the staple line during LSG has a significant clinical value: it decreased the incidence of postoperative bleeding, postoperative leakage; moreover, it also significantly prolonged the operative time and but did not change hospital stay. More high-quality and large sample RCTs are expected to get more accurate results.

Abstract
The modulation of the gut microbiota was recently deemed one of the mechanisms responsible for the excellent outcomes of bariatric surgery. However, to date, only few studies have assessed this, and they have high heterogeneity. In the present study, next-generation 16S ribosomal DNA amplicon sequencing was used to characterize the gut microbiota of healthy volunteers, as well as patients prior to and after sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). Significant differences in α diversity, β diversity and species were identified between the different groups/time-points. The results demonstrated excellent outcomes of SG and RYGB. The β diversity was lower in healthy volunteers compared with that in morbidly obese patients with or without type 2 diabetes mellitus. At 3 months after SG, the α diversity was increased and the β diversity was decreased. The abundance of certain species changed significantly after SG and RYGB. It was also revealed that the abundance of certain microbes was significantly correlated with the body mass index, fasting blood glucose and glycosylated haemoglobin. It may be concluded that bariatric surgery may cause obvious alterations in the gut microbiota and compared with healthy volunteers and obese patients without bariatric surgery, the microbiota composition of post-bariatric surgery has unique characteristics. However, studies with a larger cohort and longer follow-up may be required to confirm these results.

Abstract
BACKGROUND In recent years, transanal tube placement was reported to be an effective procedure preventing anastomotic leakage after anterior resection of rectal cancer. However, this procedure is still controversial owing to inconsistent results found in previous studies. METHODS A comprehensive literature search was performed using Pubmed, Embase, Cochrane library from the databases inception up until June 21, 2018. The methodological quality of randomized controlled trials and cohort studies were evaluated by Cochrane Collaboration's tool for assessing risk of bias and Newcastle-Ottawa Scale, respectively. Statistical analysis was performed using the RevMan 5.3 software. RESULTS 1 randomized controlled trial and 9 cohort studies were included in our meta-analysis. The randomized controlled trial was proven to be low risk according to the Cochrane Collaboration's tool for assessing risk of bias. All of the cohort studies proved a high quality according to the Newcastle-Ottawa Scale. Patients in transanal tube group had more disadvantageous preoperative demographic characteristics than patients in non-transanal tube group. The anastomotic leak rate was lower in the transanal tube group. Patients in the transanal tube group tended to have lower reoperation rates and shorter hospital stays compared with patients in the non-transanal tube group. CONCLUSION Despite various unfavorable preoperative characteristics, anastomotic leakage after anterior resection was lower in patients who received transanal tube placement compared with the control group. Transanal tube placement may be an alternative procedure of defunctioning stoma. A large sample size, multicenter RCT was needed to prove our results.

Abstract
BACKGROUND The laparoscopic mini-gastric bypass is a newly emerged surgical procedure in recent years. Owe to safe and simple process and effective outcomes, laparoscopic mini-gastric bypass has quickly become one of the most popular procedures in some countries. The safety and effectiveness of laparoscopic mini-gastric bypass versus laparoscopic sleeve gastrectomy remain unclear. METHODS A systematic literature search was performed in PubMed, Embase, Cochrane library from inception to May 20, 2017. The methodological quality of Randomized Controlled Trials and non-Randomized Controlled Trials were, respectively, assessed by Cochrane Collaboration's tool for assessing risk of bias and Newcastle-Ottawa scale. The meta-analysis was performed by RevMan 5.3 software. RESULTS Patients receiving mini-gastric bypass had a lot of advantageous indexes than patients receiving sleeve gastrectomy, such as higher 1-year EWL% (excess weight loss), higher 5-year EWL%, higher T2DM remission rate, higher hypertension remission rate, higher obstructive sleep apnea (OSA) remission rate, lower osteoarthritis remission rate, lower leakage rate, lower overall late complications rate, higher ulcer rate, lower gastroesophageal reflux disease (GERD) rate, shorter hospital stay and lower revision rate. No significant statistical difference was observed on overall early complications rate, bleed rate, vomiting rate, anemia rate, and operation time between mini-gastric bypass and sleeve gastrectomy. CONCLUSION Mini-gastric bypass is a simpler, safer, and more effective bariatric procedure than laparoscopic sleeve gastrectomy. Due to the biased data, small sample size and short follow-up time, our results may be unreliable. Large sample and multicenter RCT is needed to compare the effectiveness and safety between mini-gastric bypass and sleeve gastrectomy. Future study should also focus on bile reflux, remnant gastric cancer, and long term effectiveness of mini-gastric bypass.

Abstract
RNA interference (RNAi), including microRNAs, is an important player in the mediation of differentiation and migration of stem cells via target genes. It is used as a potential strategy for gene therapy for central nervous system (CNS) diseases. Stem cells are considered vectors of RNAi due to their capacity to deliver RNAi to other cells. In this review, we discuss the recent advances in studies of RNAi pathways in controlling neuronal differentiation and migration of stem cells. We also highlight the utilization of a combination of RNAi and stem cells in treatment of CNS diseases.

Abstract
Previous studies suggested that RsaI/PstI and DraI polymorphisms on cytochrome P450 2E1 (CYP2E1) may be associated with susceptibility to gastric cancer (GC). However, this association remains ambiguous. A meta-analysis of previously published studies was performed in an attempt to elucidate this association. The odds ratio and 95% confidence interval were used to assess the strength of the association. In the overall analyses of RsaI/PstI and DraI, no association was identified. In the subgroup analyses, RsaI/PstI was identified to increase the risk of GC in the smoking population. In addition, in the previous studies of interactions with other genes, RsaI/PstI was revealed to be associated with increased GC risks when glutathione S-transferase-µ-1 or glutathione S-transferase θ-1 was null or DraI was homozygous wild-type. However, these stratified analyses were lacking credibility due to the limitation of correlational study numbers. In conclusion, CYP2E1 polymorphisms revealed no association with the risk of GC.

Abstract
To assess the changes of calcium metabolism and osteopathy in patients with diabetes. Serum Ca, P, AKP, PTH, CT, plasma fasting blood glucose (FBG) and HbA1 as well as X-ray film of the lumbar spine were measured in 30 diabetes patients; 11 were IDDM and 19 were NIDDM as compared to controls matched for age and sex. There were no significant differences in Ca, P, and CT values in serum between the IDDM and NIDDM patients and controls, whereas the serum levels of PTH and AKP were significant increased in IDDM patients. The incidence of osteoporosis which was shown by X-ray film in NIDDM patients was higher than in those of controls. No correlation between PTH value and osteoporosis or clinical control of diabetes was observed.

Abstract
The gene HtNB confers non-lesion resistance to the fungal pathogen Exserohilum turcicum in maize. To map this gene, we developed two F₂ populations, P111 (resistant line) x HuangZao 4 (susceptible line) and P111 x B73 (susceptible). HtNB was located on chromosome 8.07 bin, flanked by MAC216826-4 and umc2218 at distances of 3.3 and 3.4 cM, respectively. HtNB appears to be a new gene responsible for resistance to northern corn leaf blight. Functions of the genes in the region between umc1384 and umc2218 were predicted. In addition, several genes were found to be related to disease resistance, such as the genes encoding Ser/Thr protein kinase and protein-like leaf senescence.

Abstract
A gene coding for an arylesterase of Vibrio mimicus was cloned. Sequence determination reveals that the esterase gene has an open reading frame of 600 nucleotides which encodes a protein of M(r) 22,300. The deduced amino acid sequence contain a pentapeptide GDSLS (residues 27-31), which was also found in the phospholipid-cholesterol acyltransferase from Aeromonas hydrophila. Substitution of Ser-29 by alanine or cysteine in the cloned gene abolished the esterase activity in the tributyrin plate assay. On the other hand, the activity was not lost when Ser-31 was changed to alanine. The cloned gene was expressed in Escherichia coli, and the protein purified by a four-step procedure. The purified protein migrated on SDS/PAGE as a single band with an apparent M(r) of 22,100. This enzyme favoured the hydrolysis of several arylesters and was classified as an arylesterase (EC 3.1.1.2). N-Terminal analysis showed that Ser-20 was the first amino acid of the mature secreted protein, suggesting that the N-terminal 19 hydrophobic amino acids served as a signal peptide.

Abstract
An immunohistochemical study of keratin was performed in forty-five cases of adenoid cystic carcinoma of salivary gland, the results were as follows: keratin was distributed in the duct system of normal salivary gland, but the acini were negative. The distribution of keratin were varied in different patterns of adenoid cystic carcinoma. The amount of synthesis of keratin was many in tubular type of high differentiated carcinoma, but, in basaloid solid type of low differentiated carcinoma, the synthesis of keratin was less; the content of keratin in cribriform and trabecular type was between the tubular type and basaloid solid type, and the former had more keratin than the latter.
