ABSTRACT
In recent years， data mining algorithms have been widely employed in scientific research within the field of traditional Chinese medicine （TCM）. The data mining algorithms are used to effectively handle and analyze the complex data in TCM formulas， providing a rational explanation for the mechanism of action. This method has proven particularly useful in uncovering patterns of compatibility and frequent combinations of herbs in TCM， thereby enhancing the reliability and accuracy of clinical diagnosis， target screening， and the study of new drugs. This paper reviews and analyzes 147 papers on TCM formula research that utilize data mining algorithms. The results indicate that data mining algorithms play a unique advantage in six sub- areas， including the study on the mechanism of action in TCM formula， the dose-efficacy of TCM formulas， the identification of core drugs pairs/groups， mining the relationships among “formulas-drug-symptom”， the discovery of new formulas， and mining the compatibility law. Notably， association rules and clustering algorithms are the most representative.
ABSTRACT
Objective:To analyze the etiological and epidemiological characteristics of hand, foot and mouth disease (HFMD) in Xi′an from 2019 to 2021, so as to provide evidence for the prevention and control of HFMD.Methods:Stool specimens and anal swabs were collected from patients with HFMD. Enteroviruses (EVs) including enterovirus 71 (EV71), coxsackievirus A16 (CVA16), CVA6 and CVA10 were detected by RT-PCR. Excel 2007 and SPSS18.0 software were used for data collection and statistical analysis, respectively. The epidemiological data of HFMD cases were analyzed by descriptive epidemiology method. The VP1 gene sequence of the representative strain of each CVA6 genotype was downloaded. Phylogenetic trees were constructed using MEGA X software and the genetic characteristics were analyzed.Results:A total of 1 531 HFMD cases were involved and 1 365 were positive for EVs with a positive rate of 89.16%. The detection rates of EV71, CVA16, CVA6, CVA10 and other EVs were 1.31% (20/1 531), 32.46% (497/1 531), 38.47% (589/1 531), 5.09% (78/1 531) and 11.23% (172/1 531), respectively. There were significant differences in the pathogen composition in HFMD cases of different clinical types (χ 2=46.14, P<0.01) and occupations (χ 2=34.65, P<0.01) as well as in different years (χ 2=462.86, P<0.01). The average age was greater in patients with CVA16 infection than in those with CVA6 or CVA10 infection ( F=6.00, P<0.01). In 2019, the HFMD cases were mainly caused by CVA16, while in 2020 and 2021, the main pathogen was CVA6. Enterovirus-positive cases showed a bimodal distribution with the main peak from May to July and the secondary peak from September to November. CVA16 was the predominant pathogen in spring and summer, and CVA6 was the predominant pathogen in autumn. CVA6 was the dominant pathogen in eight districts and counties of Xi′an; CVA16 was the dominant pathogen in six districts and counties; CVA6 and CVA16 co-circulated in one district. The CVA6 isolates belonged to two evolutionary branches of D3a subtype. Conclusions:CVA6 and CVA16 were the prevalent pathogens of HFMD and CVA6 subtype D3a circulated in Xi′an from 2019 to 2021. The pathogen composition of HFMD cases showed obvious differences in population, time and regional distribution.
ABSTRACT
Objective:To explore the role of post competency oriented interactive teaching in clinical teaching of blood purification.Methods:A total of 80 interns from the blood purification center of our hospital were selected from May 2019 to August 2020, and they were randomly divided into two groups. The control group ( n=40) were taught by routine clinical teaching, and the observation group ( n=40) was taught by interactive teaching based on the post competency. They were both taught for 3 months. The theoretical and practical assessment results of the two groups after teaching, the post competency before and after the teaching, and the satisfaction with the teaching were compared. SPSS 22.0 was used for t test and chi-square test. Results:The theoretical and practical assessment scores of the observation group after teaching were higher than those of the control group, and the difference was statistically significant (theoretical assessment: t=4.01, P<0.05; practical assessment: t=3.94, P<0.05). There was no statistically significant difference in effective communication ability score ( t=1.31, P=0.193), adaptability and coping ability ( t=1.25, P=0.216), autonomous learning and self-improvement ability ( t=0.93, P=0.356), and management ability score ( t=0.76, P=0.451). After teaching, the competency scores of the above-mentioned positions in the two groups were improved compared with those before teaching, and the scores of the observation group were higher than those of the control group, and the differences were statistically significant (effective communication ability: t=12.60, 6.63, P<0.05; adaptability and coping ability: t=11.21, 6.44, P<0.05; autonomous learning and self-improvement ability: t=10.80, 5.78, P<0.05; management ability score: t= 12.42, 6.79, P<0.05). There were significant differences in the distribution of satisfaction with teaching ( t=6.90, P=0.007) of the two groups of interns, and the total satisfaction rate of the observation group was higher than that of the control group ( t=6.49, P=0.011). Conclusion:The application of post competency oriented interactive teaching in clinical teaching of blood purification internship can not only improve the appraisal results of interns, enhance their post competency, but also improve the teaching satisfaction.
ABSTRACT
Objective:To observe any effects of electroacupuncture (EA) on urodynamics and bladder c-Kit expression in rats with urination disorders after spinal cord injury (SCI).Methods:Complete spinal cord injury models were created in female Sprague-Dawley rats by transecting the spine at the thoracic or sacral level. On day 22 after the injury, the rats with successful modeling were randomized into a thoracic spinal cord injury (TSCI) group, a TSCI+ EA group, a sacral spinal cord injury (SSCI) group and an SSCI+ EA group, each of 10. Both EA groups were given 15 minutes of EA at the Guanyuan (CV4) and Sanyinjiao (SP6) points daily for 14 days. After the intervention, urination function was evaluated using bladder volume, compliance and residual urine volume. Hematoxylin and eosin staining was used to observe any morphological changes in bladder tissues. The gene and protein expression of c-Kit in bladder tissues were detected using real-time quantitative polymerase chain reactions and western blotting.Results:Compared with the sham group, the bladder volume and compliance of the TSCI group decreased significantly, while the average residual urine volume increased significantly. In the SSCI group the average residual urine volume, bladder volume and compliance all increased significantly. The modeling altered the morphology of the bladder in all of the SCI rats. The average expression of c-Kit mRNA and protein increased significantly in TSCI group, but both decreased significantly in the SSCI group. EA improved the histological structure of the SCI rats′ bladders.Conclusions:EA can bi-directionally regulate bladder c-Kit expression, and that is a possible mechanism for improving urinary incontinence and urine retention after an SCI.
ABSTRACT
Objective:To analyze the effect of using reflective teaching method based on quality feedback in clinical teaching of hemodialysis.Methods:From January 2019 to May 2020, 76 hemodialysis interns from West China Hospital of Sichuan University were selected and randomly divided into 2 groups.

ABSTRACT
Objective:To investigate the correlation between subclinical hypothyroidism (SCH) and clinical outcomes of patients with acute ischemic stroke.Methods:From July 2014 to October 2017, patients with acute ischemic stroke admitted to Jiangsu Shengze Hospital Affiliated to Nanjing Medical University were enrolled retrospectively. Their demographic and baseline clinical and laboratory data were collected. The modified Rankin Scale was used to evaluate the clinical outcome at 3 months after the onset of symptoms. Multivariate logistic regression analysis was used to determine the independent correlation between SCH and clinical outcome of patients with acute ischemic stroke. Results:A total of 200 patients with acute ischemic stroke were enrolled, including 107 males (53.5%) and 93 females (46.5%). Their age was 69.67±11.38 years. There were 45 patients (22.5%) with SCH, 160 (80.0%) with good outcomes, and 40 (20.0%) had poor outcomes. Univariate analysis showed that there were significant differences in the baseline National Institutes of Health Stroke Scale (NIHSS) score, stroke etiology classification and the proportion of patients with SCH between the poor outcome group and the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that high NIHSS score (odds ratio 2.884, 95% confidence interval 2.005-4.147; P=0.001) and SCH (odds ratio 19.527, 95% confidence interval 2.334-163.386; P=0.006) were the independent risk factors for poor outcomes. Conclusion:High NIHSS score and SCH were associated with the poor outcomes at 3 months after the onset of acute ischemic stroke.

ABSTRACT
Objective:To investigate the predictive value of plasma lipocalin-2 (LCN2) for the clinical outcome of patients with acute minor ischemic stroke (MIS).Methods:Consecutive patients with acute MIS admitted to the Department of Neurology, Shengze Hospital Affiliated to Nanjing Medical University from October 9, 2017 to August 17, 2018 were selected prospectively. On the day of admission, the National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the degree of neurological impairment. The modified Rankin Scale was used to evaluate the clinical outcome at 90 d after the onset, and 0-1 was defined as a good outcome. Multivariate logistic regression model was used to analyze the correlation between plasma LCN2 and clinical outcome. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of plasma LCN2 for the clinical outcome of patients. Results:A total of 71 patients (68.99±11.24 years old) were enrolled in the study. Forty-six patients were male (64.8%). The median plasma LCN2 was 117.7 μg/L (interquartile range, 61.2-738.4 μg/L). Fifty-six patients (78.9%) had good outcomes, and 15 (21.1%) had poor outcomes. The age, baseline NIHSS score, plasma C-reactive protein and LCN2 of the good outcome group were significantly lower than those of the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that plasma LCN2 ≤117.7 μg/L (odds ratio 8.574, 95% confidence interval 1.755-41.874; P=0.008) and lower baseline NIHSS scores (for increasing by 1 point: odds ratio 0.396, 95% confidence interval 0.214-0.732; P=0.003) were independently related to good outcome. ROC curve analysis showed that the area under the curve for plasma LCN2 to predict a good outcome was 0.814 (95% confidence interval 0.709-0.918); the best cut-off value was 128.55 μg/L, and the corresponding sensitivity and specificity were 69.6% and 80.0%, respectively. Conclusions:Plasma LCN2 had a good predictive value for the clinical outcome of patients with acute MIS at 90 d after the onset.
ABSTRACT
BACKGROUND: Previous studies have found that the culture supernatant of the olfactory ensheathing cells is capable of promoting axonal regeneration and functional recovery after spinal cord injury, but there is a lack of research in the field of peripheral nerve. OBJECTIVE: To investigate whether olfactory ensheathing cell culture supernatant is beneficial for nerve repair after peripheral nerve injury. METHODS: Olfactory ensheathing cells were isolated and purified, to prepare the supernatant. The olfactory ensheathing cell culture supernatant was applied to the dorsal root ganglion tissue block in vitro to observe the axon growth of the dorsal root ganglion. The olfactory ensheathing cell culture supernatant was applied to a rat sciatic nerve defect model in vivo to examine its effect on axonal regeneration and myelinization of the injured nerve. RESULTS AND CONCLUSION: The purity of olfactory ensheathing cells was (94.4±3.1)%. Compared with the blank control and low dose olfactory ensheathing cell culture groups, the average length of five longest axons in dorsal root ganglion tissue mass in the high dose olfactory ensheathing cells culture group was significantly increased (P < 0.05). Immunofluorescence showed that the regenerated nerve penetrated through the defect area and the regenerated nerve was arranged orderly in the olfactory ensheathing cell culture and the autologous nerve groups, which was significantly superior to that in the blank control group. Transmission electron microscope observed that the number of regenerated nerve axons and the thickness of myelin sheath in the olfactory ensheathing cell culture group were significantly higher than those in the blank control group (P < 0.05). These results indicate that the supernatant of the olfactory ensheathing cells can promote axonal regeneration after peripheral nerve injury and the myelination of the regenerated axons, which provides a new olfactory ensheathing cells-based acellular therapy for peripheral nerve injury.

ABSTRACT
Objective:To explore the protective effect of nerve plane-oriented laparoscopic total mesorectal excision (NPO+ LTME) for postoperative urinary and sexual function in patients with rectal cancer.Methods:Retrospective analysis was performed on rectal cancer patients who received surgical treatment at Renmin Hospital of Wuhan University from Jan 2016 to Dec 2018, including 114 patients in the NPO+ LTME group and 92 patients in the laparoscopic TME combined with pelvic autonomic nerve preservation (LTME+ PANP) group. Surgical and tumor-related indicators were recorded and compared between the two groups, and postoperative urination and sexual function were followed up.Results:There was no significant difference in baseline indicators between the two groups ( P>0.05). The operative time of the two groups was (150±7) min and (154±7) min, respectively ( t=3.585, P<0.05). Intraoperative bleeding was (9±3) ml and (15±6) ml ( t=7.654, P<0.05), respectively.Three months after surgery, the rate of urinary dysfunction in the NPO+ LTME group was lower than that in the LTME+ PANP group ( Z=2.549, P<0.05), but there was no difference between the two groups 6 and 12 months after surgery ( Z=0.814, P>0.05 and Z=1.275, P>0.05). At 3, 6 and 12 months after surgery, the erectile function in NPO+ LTME group was better than that in LTME+ PANP group ( Z=4.917, P<0.05; Z=4.947, P<0.05 and Z=4.081, P<0.05); The rate of ejaculation dysfunction was also lower than that of the LTME+ PANP group ( Z=4.464, P<0.05; Z=4.948, P<0.05 and Z=4.434, P<0.05); In addition, postoperative female sexual function was superior to LTME+ PANP group ( Z=2.532, P<0.05; Z=2.364, P<0.05; Z=2.076, P<0.05). Conclusion:NPO+ LTME has good surgical safety and also has certain advantages for patient sexual function and early urinary function protection.

ABSTRACT
Objective@#Using previous total mesorectal excision with pelvic autonomic nerve preservation (PANP+TME) and simple total mesorectal excision (TME) without emphasis on retained nerves as control, we explore the advantages of nerve plane-oriented laparoscopic total mesorectal excision (NPO+LTME) on urinary and sexual function.@*Methods@#A retrospective cohort study was carried out. Case inclusion criteria: (1) male patients with pathologically confirmed middle and low rectal adenocarcinoma (4 to 11 cm from the anus); (2) stage T1-2tumor; (3) normal sexual life before operation. Exclusion criteria: (1) no pathological diagnosis before surgery; (2) local recurrence or distant metastasis; (3) preoperative neoadjuvant chemoradiotherapy; (4) opensurgery and laparoscopic surgery conversionto open; (5) no follow-up data. According to the above criteria, clinical data of 173 male patients with low and middle rectal adenocarcinoma who underwent radical operation for laparoscopic rectal cancer from July 2003 to July 2018 at the Department of Gastrointestinal Surgery, Wuhan University People′s Hospital were collected. According to different surgical methods, patients were divided into TME group (58 cases), PANP+TME group (63 cases) and NPO+LTME group (52 cases). There were no significant differences in the baseline data including age, body mass index and pathological examination between the 3 groups (all P>0.05). The nerve plane referred to the nerve, the adipose tissue, the extremely finecapillaries around the nerve with overlying fine membranous tissue. NPO+LTME referred to the process of laparoscopic TME guided by the nerve plane, performing in the loose connective tissue between the nerve plane and the rectal properfascia, in order to ensure the integrity of the nerve plane, and maximally protect the patient's urinary and reproductive functions. The operation time, intraoperative blood loss, urinary catheter removal time, urinary function grading, postoperative first erection time, and erectile function and ejaculation function were observed and compared among the 3 groups at 3- and 6-month after operation.@*Results@#In the NPO+LTME group, the PANP+TME group and the TME group, the operation time was (181.9±24.5) minutes, (176.7±29.2) minutes and (137.7±16.2) minutes, respectively (F=54.868, P<0.001); the intraoperative blood lost was (6.0±1.4) ml, (6.5±1.8) ml and (12.8±4.6) ml, respectively (F=95.016, P<0.001); the time to postoperative removal of the catheter was (2.4±1.1) days, (3.7 ±1.7) days and (6.5±2.4) days, respectively (F=79.409, P<0.001); the first postoperative erection time was (1.6±0.6) days, (8.9±2.7) days and (15.9±6.8) days (F=177.677, P<0.001), respectively, whose differences were all statistically significant (all P<0.01). In comparison of urinary function grading, the proportion of grade I (normal function, no urinary dysfunction) in the NPO+LTME, the ANP+TME group and the TME group was 84.1% (53/63), 39.7% (23/58) and 19.2% (10/52), respectively, and the difference was statistically significant (H=52.915, P<0.001). At postoperative 3- and 6-month, proportion of patients with grade I erectile function (normal erectile function) was 77.8% (49/63) and 85.7% (54/63), 44.8% (26/58) and 53.4% (31/58), 28.8% (15/52) and 48.1% (25/52) in the NPO+LTME group, the PANP+TME group, and the TME group, respectively. The differences were statistically significant (H=91.709, P<0.001; H=79.692, P<0.001). The proportion of patients with grade I ejaculation function (with ejaculation, no abnormalities in routine semen examination before and after surgery) at 3- and 6-month after surgery in the NPO+LTME group, the PANP+TME group and the TME group was 82.5% (52/63) and 87.3% (55/63), 53.4% (31/58) and 60.3% (35/58), 28.8% (15/52) and 46.1% (24/52), respectively. The differences were statistically significant as well (H=86.543, P<0.001; H=78.667, P<0.001). Patients in the NPO+LTME group had no grade III erections and ejaculation disorders.@*Conclusion@#The surgical procedure of NPO+LTME can promote the recovery of postoperative neurological function and preserve urination and sexual function better.
ABSTRACT
Objective@#To evaluate the safety and effectiveness of repeated transcranial magnetic stimulation (rTMS) for treating non-fluent aphasia after stroke.@*Methods@#Forty-five stroke survivors with non-fluent aphasia were randomly divided into a 0.5 Hz group, a 1 Hz group and a sham group, each of 15. In addition to routine linguistic training, the three groups were given rTMS over the inferior frontal gyrus of the right hemisphere at the corresponding frequency or sham stimulation. Before as well as 5 and 10 days after the treatment, all of the subjects were evaluated using the Chinese version of the Western Aphasia Battery (WAB). The occurrence of adverse events was also observed.@*Results@#Before treatment, no significant differences were observed in the groups′ average aphasia ratio, spontaneous speech, listening comprehension, retelling and naming using the WAB. After 5 and 10 days significant increases were observed in the average WAB scores of all three groups, but the listening comprehension of the 0.5 Hz group was significantly better than that of the sham group 10 days later, as was the spontaneous speech of the 1 Hz group.@*Conclusion@#rTMS at either 1 Hz or 0.5 Hz can improve the linguistic functioning of stroke survivors with non-fluent aphasia. Both 0.5 Hz and 1 Hz rTMS are safe, but the latter is more effective.
ABSTRACT
Objective@#To explore the establishment of an evaluation indicator system for disease prevention and control workload at public hospitals, based on the current situation of disease prevention and control work undertaken by public hospitals of and above secondary level in Beijing, and to provide evaluation assistance for them to do better in this regard.@*Methods@#This research was based on our pervious study of the current situation description of disease prevention and control work undertaken by public hospitals in Beijing, by which the contents of routine disease prevention and control work at hospitals have been initially established. The unit strength of each work was consulted, and the disease prevention and control work was classified according to the results. Meanwhile the consistency test of the work intensity within the category was carried out. After integration, the classification and evaluation indicator of disease prevention and control work in public hospitals of and above secondary level in Beijing was finally established.@*Results@#The workload evaluation indicator system was divided into eight parts: report work, report quality control work, monitoring work, training work, work of public health related clinical diagnosis and treatment, work of clinical examination and vaccination, work of sampling and testing and public health related consultation work. The work intensity of each category ranged from 4.78 to 7.34.@*Conclusions@#The evaluation indicator system of workload is suitable for the evaluation of basic works. The unified transformation of workload by using the value of work intensity is conducive to management evaluation, but the limitation of the indicators exists in time and region, making it necessary to adjust by the local specific situation at the promotion and application level.
ABSTRACT
Objective@#To investigate the implementation of disease prevention and control services at tertiary public general hospitals in Beijing for providing evidences to explore and build a scientific evaluation model of disease control service in medical institutions.@*Methods@#June to September 2018, through a questionnaire survey of 50 tertiary public general hospitals in Beijing, a descriptive analysis was made on the department setting, personnel allocation and service provision status of disease prevention and control at tertiary public general hospitals in Beijing.@*Results@#Among the 44 investigated public tertiary general hospitals, 26(59.1%) medical institutions have set up departments of disease prevention and control. The average staffing of 44 hospitals was 5.8 persons for the department. Professional composition of the staff was mostly nursing and clinical disciplines, and the academic and professional titles were mostly undergraduate and intermediate degrees respectively. Overall performance of disease prevention and control services in public tertiary general hospitals was satisfactory. The work was well carried out in communicable disease control and death-surveillance management, namely in immunoprophylaxis, chronic noncommunicable diseases and injury monitoring, which varies widely in mental health services, occupational health management, environmental and health monitoring and other functions.@*Conclusions@#Professional ability and management level of personnel still need to be improved. We should further clarify the joint prevention and control mechanism of the " Three-in-one" nature of disease control institutions, medical institutions and communities, promote the combination of medical treatment and prevention, and explore the classification and grading evaluation of disease control work based on the types and quantity requirements of disease prevention and control services undertaken by hospitals, so as to effectively improve the level of disease control services in hospitals.
ABSTRACT
Objective@#To analyze the relationship between tumor deposits(TD) and clinicopathological features of locally advanced gastric cancer(LAGC) patients.@*Methods@#The clinicopathological characteristics of 300 LAGC patients undergoing radical gastrectomy in Renmin Hospital of Wuhan University from Jan 2014 to Jul 2017 were collected. The relationship between clinicopathological features and prognosis of LAGC patients and TD status in LAGC patients were analyzed retrospectively.@*Results@#TD were positive in 65(21.7%) patients. Univariate analysis showed that the depth of invasion, lymph node metastasis, pTNM stage, tumor size, vascular invasion, preoperative tumor markers were correlated with the status of TD(all P<0.05). Multivariate Logistic regression analysis showed that lymph node metastasis, pTNM stage, vascular invasion and depth of invasion were independent risk factors for positive TD (allP<0.05). Univariate analysis on prognosis of LAGC patients showed lesion location, degree of differentiation, lymph node metastasis, pTNM stage, tumor size, positive TD, number of TD and vascular invasion are associated with prognosis of LAGC (all P<0.05). Multivariate COX regression analysis showed that the number of TD >3 was an independent risk factor for the prognosis of LAGC patients(HR=2.242, 95% CI: 1.484-3.386, P=0.000). The median survival time of TD-positive LAGC was less than TD-negative group(χ2=91.077, P<0.001). The median survival time of TD number>3 group was significantly shorter than that in TD number<3 group and TD-negative group(χ2=192.969, P<0.001).@*Conclusions@#TD are closely related to tumor stage in LAGC patients. The status of TD is an independent risk factor for the prognosis of LAGC. Multiple TDs indicate poor prognosis of LAGC patients.
ABSTRACT
Objective To explore the establishment of an evaluation indicator system for disease prevention and control workload at public hospitals, based on the current situation of disease prevention and control work undertaken by public hospitals of and above secondary level in Beijing, and to provide evaluation assistance for them to do better in this regard.Methods This research was based on our pervious study of the current situation description of disease prevention and control work undertaken by public hospitals in Beijing, by which the contents of routine disease prevention and control work at hospitals have been initially established. The unit strength of each work was consulted, and the disease prevention and control work was classified according to the results. Meanwhile the consistency test of the work intensity within the category was carried out. After integration, the classification and evaluation indicator of disease prevention and control work in public hospitals of and above secondary level in Beijing was finally established. Results The workload evaluation indicator system was divided into eight parts:report work, report quality control work, monitoring work, training work, work of public health related clinical diagnosis and treatment, work of clinical examination and vaccination, work of sampling and testing and public health related consultation work. The work intensity of each category ranged from 4.78 to 7.34. Conclusions The evaluation indicator system of workload is suitable for the evaluation of basic works. The unified transformation of workload by using the value of work intensity is conducive to management evaluation, but the limitation of the indicators exists in time and region, making it necessary to adjust by the local specific situation at the promotion and application level.
