Objective:To investigate the safety and short-term efficacy of laparoscopic pro-ximal gastrectomy (LPG) for proximal gastric cancer and adenocarcinoma of esophagogastric junction.Methods:The retrospective cohort study was conducted. The clinicopathological data of 385 patients with proximal gastric cancer and adenocarcinoma of esophagogastric junction who underwent LPG in the 15 medical centers, including the First Affiliated Hospital of Xiamen University et al, from January 2014 to March 2022 were collected. There were 304 males and 81 females, aged (63±9)years. Of the 385 patients, 335 cases undergoing LPG were divided into the laparoscopic group and 50 cases undergoing open proximal gastrectomy were divided into the open group. Observation indicators: (1) intraoperative and postoperative situations; (2) follow-up; (3) stratified analysis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Intraoperative and postoperative situations. The operation time, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, cases with postoperative pathological staging as stage 0?Ⅰ and stage Ⅱ?Ⅲ, duration of postoperative hospital stay, cases with postoperative early complications were (212±96)minutes, 270, 65, 177, 107, 10(range, 8?14)days, 40 in patients of the laparoscopic group, with 51 cases missing the data of postoperative pathological staging. The above indicators were (174±90)minutes, 39, 11, 22, 28, 10(range, 8?18)days, 10 in patients of the open group. There were significant differences in the opera-tion time and postoperative pathological staging between the two groups ( t=2.62, χ2=5.93, P<0.05), and there was no significant difference in the reconstruction of digestive tract, duration of post-operative hospital stay, postoperative early complications between the two groups ( χ2=0.19, Z=0.40, χ2=2.50, P>0.05). (2) Follow-up. Of the 385 patients,202 cases were followed up during the post-operative 12 months, including 187 cases in the laparoscopic group and 15 cases in the open group. Cases with reflux esophagitis, cases with esophageal anastomotic stenosis were 48, 11 in patients of the laparoscopic group, versus 5, 2 in patients of the open group, showing no significant difference in the above indicators between the two groups ( P>0.05). The body mass index (BMI), hemoglobin (Hb), albumin (Alb) at postoperative 6 months and 12 months were (21±3)kg/m 2, (130±15)g/L, (40±4)g/L and (21±3)kg/m 2, (132±14)g/L, (41±4)g/L in patients of the laparoscopic group, versus (21±3)kg/m 2, (121±19)g/L, (37±5)g/L and (21±3)kg/m 2, (125±21)g/L, (43±6)g/L in patients of the open group. There were significant differences in postoperative Hb between the two groups ( Fgroup=5.88, Ftime=5.49, Finteraction=19.95, P<0.05) and there were significant differences in time effect of postopera-tive BMI and Alb between the two groups ( Ftime=9.53, 49.88, P<0.05). (3) Stratified analysis. ① Incidence of postoperative of reflux esophagitis and esophageal anastomotic stenosis in patients with different reconstruction of digestive tract. Of the 202 patients, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis were 168 and 34, respectively. The incidence rates of postoperative of reflux esophagitis were 26.79%(45/168)and 23.53%(8/34)in cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, showing no significant difference between them ( χ2=0.16, P>0.05). Cases undergoing esophageal anastomotic stenosis were 13 in patients with reconstruction of diges-tive tract as esophagogastric anastomosis. ② The BMI, Hb, Alb in patients with different reconstruc-tion of digestive tract. The BMI, Hb, Alb were (24±3)kg/m 2, (135±20)g/L, (41±5)g/L in the 168 patients with reconstruction of digestive tract as esophagogastric anastomosis before the operation, versus (23±3)kg/m 2, (130±19)g/L, (40±4)g/L in the 34 patients with reconstruction of digestive tract as esophageal-jejunal anastomosis before the operation, showing no significant difference between them ( t=1.44, 1.77, 1.33, P>0.05). The BMI, Hb, Alb at postoperative 6 months and 12 months were (21±3)kg/m 2, (128±16)g/L, (39±4)g/L and (21±3)kg/m 2, (131±16)g/L, (41±4)g/L in the 168 patients with reconstruction of digestive tract as esophagogastric anastomosis, versus (20±4)kg/m 2, (133±13)g/L, (43±3)g/L and (21±3)kg/m 2, (135±12)g/L, (44±3)g/L in the 34 patients with reconstruction of digestive tract as esophageal-jejunal anastomosis. There were significant differences in the group effect and time effect of postoperative Alb between patients with different reconstruction of diges-tive tract ( Fgroup=15.82, Ftime=5.43, P<0.05), and there was also a significant difference in the time effect of postoperative BMI between them ( Ftime=4.22 , P<0.05). Conclusion:LPG can be used to the treatment of proximal gastric cancer and adenocarcinoma of esophagogastric junction, with a good safety and short-term efficacy.

Lu Dangshen is the geoherb in Shanxi Province. The content of Codonopsis pilosula polysaccharides (CPP) in Lu Dangshen is more than that in other Codonopsis Radix from other regions. Glycosyltransferase is the key enzyme for the synthesis of bioactive components, such as CPP and tangshenoside I. Based on the transcriptome data of C. pilosula [Codonopsis pilosula (Franch.) Nannf.] from different producing areas, this study carried out functional annotation of GO and KEGG, conservative domain analysis, phylogenetic tree analysis and expression pattern analysis of glycosyltransferase genes in C. pilosula to provides a theoretical basis for exploring the mechanism of genuineness formation in Lu Dangshen. In this study, 98 glycosyltransferase genes were screened and identified, which belonged to GT family 1, GT family 2, GT family 90 and other families. By GO functional annotation, it was found that most of the glycosyltransferase genes had catalytic activity. Analysis of KEGG functional annotation showed that C. pilosula glycosyltransferase was mainly involved in glycan organism and terpenoid and polyketone metabolism. Among them, conserved domain of 42 glycosyltransferase genes in GT family 1 was [X]-W-[2X]-Q-[3X]-[LH]-[5X]-[FLTHCGWNS]-[2X]-E-[4X]-[GVP]-[4X]-P-[4X]-Q-[2X]-[NAK]. Phylogenetic tree analysis based on the glycosyltransferase sequence in Arabidopsis thaliana showed that C. pilosula glycosyltransferases were mainly located in Arabidopsis thaliana UGT73, 72 and 85 branches. Gene expression pattern analysis showed that expression of CpUGT73AH2 was higher in Lu Dangshen than that in Baitiaodang and could respond to drought and low temperature stress. In conclusion, a glycosyltransferase gene CpUGT73AH2, which is involved in the metabolism of terpenoids and polyketides and can respond to environmental stress, was screened from the C. pilosula glycosyltransferase family 1, which was used to further study the role of C. pilosula glycosyltransferase in Lu Dangshen. It laid a theoretical foundation for further study on the role of C. pilosula glycosyltransferase in the formation of Lu Dangshen.

BACKGROUND:The hedgehog pathway has paid an important role in the progress of chondrogenesis from bone marrow mesenchymal stem cells. However, the definite signal transduction pathway and cross-talking relationship with other common signal pathways are stil poorly understood and the researches related to this field is to continue as a hotspot in the future study. OBJECTIVE:To investigate the research progress of hedgehog signal pathway on the regulation of the chondrogenesis from bone marrow mesenchymal stem cells and the relationship between hedgehog and other signal pathways in the process. METHODS:A computer-based online search in CNKI, PubMed and Google Scholar databases was performed using key words of“Hedgehog, IHH, SHH, bone marrow mesenchymal stem cells, cartilage, chondrogenesis”in English and Chinese, respectively. Literatures related to the process of chondrogenesis from bone marrow mesenchymal stem cells were included and 36 articles were extensively summarized for review. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cells are currently accepted optimal cellseeds for the cartilage tissue engineering, and hedgehog is a critical signal molecule in the development of skeletal system. The IHH and SHH in hedgehog signal closely participate in control ing the processes of bone marrow mesenchymal stem cellproliferation and chondrogenesis, chondrocyte phenotype maintenance and cooperation with other common single pathways. However, the specific signal transduction mechanism and cross-talking contact with other signal pathways stil need to be further studied, and it stands for the future research directions.

Objective To evaluate the clinical efficacy and safety of tirofiban in the treatment of patients who received percutaneous coronary intervention( PCI).Methods Eighty-seven patients with acute coro-nary syndrome treated with PCI were recruited from Feb 2011 to Sep 2013 prospectively.They were randomly divided into treatment group ( n=41 ) and control group ( n=46 ).Based on the regular anticoagulant therapy , patients in the treatment group were given tirofiban 10 mg· kg-1 immediately at the early time of pre -PCI, followed by 0.15μg· kg -1 · min -1 intravenous infusion until 36 hours after PCI.Patients in the control group were only given the regular anticoagulant therapy at the early time of pre-PCI.And the major adverse cardiovascular events (MACE), myocardial enzymes and complication of the two groups were observed in the two groups.Results The rate of MACE (9.8%, 4/41) in treatment group were much lower than that in the control group (26.1%, 12/46) ( P<0.05 ).The myocardial enzyme indicators of 24 hours after PCI was lower than that in the control group;but there was no difference in bleeding complications between the two groups ( P>0.05 ) . Conclusion MACE can be significantly decreased in patients who were treated with PCI by using tirofiban in the emergency department and tiro-fiban does not increase the risks to develop bleeding complications.

Objective To compare the clinical efficacies regarding femoral artery or radial artery approaches on coronary artery interventional therapies.Methods 360 patients were randomly divided into intervention group via femoral artery (TFI) or transradial coronary intervention (TRI) group.Postoperative observation on the two said groups of patients with vascular lesion characteristics,feasibility factors ( success rate of interventional therapy puncture,time of operation and hospitalization)and complications,were made.Results There were no significant differences between the two groups on the characteristics of vascular lesion (P＞0.05).Success rates of the two groups were 97.78％ and 96.67％ respectively.The differences on success rate,time of operation were not statistically significant (P＞0.05) while the average time of puncture,the mean duration of hospitalization and the rates of complications were significantly different ( P＜ 0.05 ).Conclusion The two methods under comparison had similar success rate and feasibility.However,the complications related to radial artery interventional therapy were much less than the femoral artery interventional therapy.As having better safety,radial artery interventional therapv seemed to have applicable value on clinical oractice.

OBJECTIVETo investigate the prevalence of hearing impairment and ear diseases in old people and provide scientific data for drawing up the prevention and treatment strategies.

METHODSUsing the probability proportion to size (PPS) method, 1261 people over 60 years were investigated in 40 clusters in Jiangsu Province with the WHO protocol.

RESULTSThe prevalence of hearing impairment was 58.1% (the standardized rate: 59.5% in the whole country, 60.9% in Jiangsu province). Degrees of hearing impairment were mild (33.1%), moderate (17.8%), severe (5.9%) and profound (1.3%). The prevalence of hearing disability was 25.0% (the standardized rate: 26.6% in the whole country, 28.1% in Jiangsu province). There were significant difference of the prevalence between male and female, as well as urban and rural, and different ages. The prevalence of the ear diseases was auricle malformation (0.2%), wax (1.7%), otitis externa (0.1%), fungi (0.5%), serous otitis media (1.2%), chronic suppurative otitis media (1.6%), dry perforation of tympanic membrance (2.3%). The causes of hearing impairment were ear diseases (2.9%), non-infectious condition (92.6%), genetic condition (0.3%) and undetermined causes (4.2%). Of which, 31.1% of persons needed hearing aids while 2.3% of persons needed medicine treatment, but 0.9% of persons needed non-urgent surgery and 1.0% of persons needed other treatment.

CONCLUSIONSThe prevalence of hearing impairment and disability in the old rised obviously than the last investigation in 1987. It was a heavy burden for social development in China. The government and the whole society should take more concern about the problem. The scientific strategies of prevention and treatment were urgently needed and implemented.
