Objective:
To investigate the factors influencing the development of gastric cancer in Chinese populations, so as provide insights into creating a model for predicting gastric cancer incidence among Chinese populations.
Methods:
The case-control and cohort studies pertaining to factors affecting the development of gastric cancer were retrieved in electronic Chinese and English databases, including CNKI, Wanfang Data, VIP, PubMed, Web of Science and Embase from their inception until September 30, 2021. A meta-analysis was performed using R package version 4.1.0. Sensitivity analysis was performed using the “leave-one-out” evaluation procedure, and the publication bias was evaluated using the Egger regression test and the trim-and-fill procedure.
Results:
A total of 5 301 publications were screened and 116 eligible studies were included in the final analysis, including 103 case-control studies and 13 cohort studies, which covered approximately 3.23 million study subjects. A total of 45 factors affecting the development of gastric cancer were collected, and there were less than 4 publications reporting 7 factors, which were only qualitatively described. There were 38 factors included in the final meta-analysis. A total of 21 factors were identified as risk factors of gastric cancer, including a history of gastrointestinal diseases (pooled OR=4.85, 95%CI: 3.74-6.29), H. pylori infection (pooled OR=3.18, 95%CI: 2.35-4.32), binge eating and drinking (pooled OR=2.88, 95%CI: 2.09-3.97) and a family history of tumors (pooled OR=2.78, 95%CI: 2.17-3.56), and 10 factors as protective factors, including vegetable intake (pooled OR=0.48, 95%CI: 0.38-0.61), tea consumption (pooled OR=0.55, 95%CI: 0.47-0.64), administration of aspirin (pooled OR=0.53, 95%CI: 0.31-0.92) and administration of statins (pooled OR=0.59, 95%CI: 0.44-0.80). Sensitivity analyses of eating moldy food frequently, white meat intake, favoring spicy food and administration of sulfonylureas were not robust. Following correction with the trim-and-fill procedure, there was still a publication bias pertaining to high income, diabetes, administration of stains, alcohol consumption, tea consumption and white meat intake.
Conclusions
The development of gastric cancer is associated with a medical history of gastrointestinal disease, H. pylori infection, family history of tumors and poor dietary habits. Risk and protective factors of gastric cancer are recommended to be included in models used to predict gastric cancer incidence among Chinese populations.

Objective To get an understanding of the patient experience in public hospitals nationwide, and to evaluate the implementation of the Action Plan to Improve Health Care. Methods Supported by the mobile technology, from September 6, 2017 to December 15, 2018, the authors conducted an online survey that measured the satisfaction of both inpatients and outpatients at secondary and tertiary hospitals across the country. 15 questions from six dimensions including registration experience, patient-doctor communication, nurse-patient communication, the healthcare signage system, responsiveness of care providers and privacy protection were prepared for outpatients, while 20 questions from nine aspects such as nurse-patient communication, patient-doctor communication, pain management, medication communication, admission and discharge information, responsiveness of care-givers, food service, friendliness to patient family, and the healthcare signage system were directed at inpatients. Descriptive statistical analysis was used to describe the basic features of the data. Results 9.18 million valid responses from outpatients and another 5.38 million from inpatients were obtained. The overall satisfaction rate with outpatient services had reached a score of 90.45 points where nurse-patient communication stands out as the top-rated dimension and privacy protection gets the lowest rating. On the other hand, the inpatient satisfaction stands at a score of 93.01 with friendliness to patient family receiving the top score and patient-doctor communication the lowest. Conclusions Despite the positive feedback Chinese patients give on the outpatient care they receive, we should make efforts to improve the outpatient care environment, the wayfinding system, privacy protection, and responsiveness of care-givers.

Objective:This study aimed to compare the detection efficacy of transrectal ultrasound-guided transrectal cognitive fusion targeted+ systematic prostate biopsy and transperineal cognitive fusion targeted + systematic biopsy in patients with suspected prostate cancer (PCa). In addition, the relative clinical characteristics of PCa were evaluated.Methods:A total of 385 patients with suspected prostate cancer in the affiliated hospital of Qingdao University from May 2019 to November 2019 were retrospectively analyzed. All patients met the prostate biopsy criterion, who underwent transrectal(n=275)and transperineal(n=110)prostate biopsy respectively. There were no significant differences of mean age [(70.7±7.3)years vs.(69.2±8.4) years], PSA [(55.12±116.96)ng/ml vs. (63.41±315.34)ng/ml], prostate volume [(55.96±35.26)ml vs. (64.35±55.99)ml] between two groups. According to preoperative prostate magnetic resonance imaging combined with intraoperative ultrasound, 2-4 needles targeted puncture of suspected lesion were performed, followed by 12 needle systematic prostate biopsy. The detection rate of prostate cancer between two biopsy ways were compared. The related factors of PCa including age, prostate volume and PSA level were collected for univariable and multivariable logistic analysis. The cancer detection rate was compared and logistic regression was used to assess the impact of patient characteristics on PCa detection.Results:For all patients, the detection rate with cancer between transrectal group and transperineal group were 121/275(40.0%) and 67/110(60.9%), respectively. The transperineal group detected a higher rate of PCa ( P=0.003)and more clinically significant prostate cancers (csPCa) (54.6% vs.36.7%, P=0.001) than that of the transrectal group, there were significant differences between two groups ( P<0.05). Univariate and multivariate logistic regression analysis revealed that PSA( OR=1.025, P=0.001) and prostate volume( OR=0.984, P=0.001)were two independent factors for the detection rate of prostate cancer between two biopsy ways( P<0.05). The effect of age on the detection rate of PCa in the transperieal group was significantly lower than that of the transrectal group( OR=0.037, P=0.238 vs. OR=0.053, P=0.002). Conclusion:The transperieal biopsy could find more PCa than the transrectal biopsy. PSA level and prostate volume could affect the detection rate of cancer between two prostate biopsy ways.

Objective:To explore the feasibility and safety of long-distance urological nephrotomy with the support of 5G communication technology by using the domestic robot.Methods:Clinical data of the patients with remote robot-assisted laparoscopic nephrectomy, which were completed from March to April 2021 by the Affiliated Hospital of Qingdao University (as the host hospital where the main operating system located) were retrospectively analyzed. There were 3 patients, including 2 males and 1 female.The average age was 61 (49-73) years, and the average body mass index was 23.73 (20.00-27.76) kg/m 2. One patient had a ASA classification of grade 2, and the other 2 patients had grade 3. All patients met the surgical criteria for non-functional nephrectomy. The chief surgeon who performing the telesurgery was located at the Affiliated Hospital of Qingdao University. The surgeon remotely controlled the bedside operating system (slave system) in 3 local hospitals located in other cities in Shandong Province (network communication distances of 82.5, 141 and 229 km, respectively) by manipulating the master system located in Qingdao. Images and operating instructions during surgery were transmitted using 5G wireless communication technology. Intraoperative network conditions, robot operation, and patient perioperative data were summarized. Results:All 3 tele-nephrectomies were successfully completed. The average network signal latency time was 27.3 (23-30) ms, with no packet loss, and the average total latency time was 177.3(173-180) ms. The mean resection time was 79.3 (52-111) min, and the average intraoperative blood loss was 31.1 (15.6-41.9) ml. There were no network related adverse events occurred during the operation, and the robot-related adverse events occured 3 times, all three of which were characterized by inconsistent master and slave movements of the manipulator arm and the bedside robotic arm. None of these adverse events affected the successful performance of the telesurgery. The mean postoperative exhaust time was 60.5 (38.5-78.0) h. The mean postoperative VAS score at 24 hours was 3.7 (3-4). The Clavien-Dindo classification were all grade I. No significant abnormality was found on the 30th day after surgery, and the patients recovered well at the follow-up until 6 months postoperatively.Conclusions:It is safe and feasible to perform remote robot-assisted laparoscopic nephrectomy based on 5G communication technology with no serious adverse events or surgical complications.However, the conclusion needs to be further verified by large sample and multi-center prospective study.

OBJECTIVE To study the pharmacokinetic changes in the plasma and cerebrospinal fluid of bronchial asthma model rats after the complication of Ephedra sinica and Prunus armeniaca. METHODS SD male rats were randomly divided into blank group, model group, E. sinica group (12 g/kg, calculated by raw drug, similarly hereinafter), P. armeniaca group (6 g/kg) and E. sinica-P. armeniaca drug-pair group (12 g/kg of E. sinica+6 g/kg of P. armeniaca), with 6 rats in each group. Except for the blank group, the bronchial asthma model was induced by spraying rats in each group with an equal volume mixture of 2% acetylcholine chloride and 0.4% histamine phosphate, once a day, for 7 d. One hour before modeling every time, rats in each group were gavaged with the corresponding drug/normal saline, once a day, for 7 d. After the final administration and provocation of asthma, blood and cerebrospinal fluid collection were performed at different time points. The plasma and cerebrospinal fluid samples were pre-treated (with geranylgeranyl as the internal standard), and the mass concentrations of ephedrine/pseudoephedrine, methyl ephedrine and amygdalin in both samples were determined by liquid chromatography-tandem mass spectrometry. DAS 2.0 pharmacokinetic software was used to determine the main pharmacokinetic parameters through the non-atrial chamber model and to compare the changes of the pharmacokinetic parameters before and after the combination of the two drugs. RESULTS Compared with E. sinica group, cmax and AUC0-21.33 h (or AUC0-10.67 h) of ephedrine/pseudoephedrine and methyl ephedrine in the plasma and cerebrospinal fluid of rats were significantly reduced in E. sinica-P. armeniaca drug-pair group, while CLZ/F and VZ/F were significantly increased (P<0.05 or P<0.01); tmax of methyl ephedrine in the cerebrospinal fluid was significantly shortened (P< 0.05).Compared with P. armeniaca group, the t1/2 of amygdalin in the plasma of rats in E. sinica-P. armeniaca drug-pair group was significantly shortened, and CLZ/F was significantly increased (P<0.01); the tmax of bitter amygdalin in the cerebrospinal fluid was significantly shortened, and the AUC0-10.67 h, CLZ/F, and VZ/F were significantly increased (P<0.01). CONCLUSIONS The combination of E. sinica and P. armeniaca accelerates the absorption and elimination of ephedra alkaloids, thus reducing the accumulation of ephedra alkaloids in the bronchial asthma model rats.
