Objective:To understand the satisfaction evaluation of contracted residents with " Internet plus" family doctor services and to explore its influencing factors.Methods:From November to December 2021, a stratified random sampling method was used to select 360 contracted residents who had utilized " Internet plus" family doctor services from community health service centers or township health clinics in various counties, cities, or districts of a city in Shandong Province for on-site questionnaire surveys. The purpose was to understand their awareness and satisfaction with the " Internet plus" family doctor services. At the same time, key informant interviews were conducted with contracted residents according to the principle of intensity sampling and information saturation, to collect their opinions and suggestions on the implementation process and model construction of " Internet plus" family doctor services. Descriptive analysis was performed on the data, and a binary logistic regression model was used to analyze the factors affecting the satisfaction of contracted residents with " Internet plus" family doctor services.Results:352 valid questionnaires were obtained. Among the respondents, 108 (30.6%) were very familiar or relatively familiar with the " Internet plus" family doctor service policy, and 251 (71.3%) expressed a high level of satisfaction with the overall " Internet plus" family doctor service. Gender, monthly income status, frequency of participation in health education activities, and satisfaction with the doctor′s daily service attitude, medical technical level, medical service charge level, and the level of communication between the service team and family members were factors affecting the satisfaction of contracted residents with " Internet plus" family doctor services ( P<0.05). Interview results showed that 38 people (95.0%) believed that there were issues with the current implementation of " Internet plus" family doctor services in China, such as the lack of an effective policy support environment, the need to improve the publicity and mobilization effects of contracting institutions, poor service cognition levels among the population, concerns about service quality, misunderstandings about internet-related concepts, network " panic" caused by electronic fraud phenomena, and cultural level differences among the elderly that limited the use of services. Conclusions:The overall satisfaction of contracted residents with the " Internet plus" family doctor services was relatively good. Various factors affected the satisfaction evaluation of contracted residents. It is important to focus on the differences in service psychological perception among contracted residents with different demographic characteristics, strengthen the construction of service teams and service platforms, and improve the public′s cognition and participation in " Internet plus" family doctor services to promote the continuous development of " Internet plus" family doctor services.

ObjectiveTo screen out the transcriptomes related to the intervention of Wuzi Yanzongwan on the spermatogenic function of semi-castrated male mice， and to explore its potential mechanism in the intervention of the progress of low spermatogenic function. MethodBalb/c mice were randomly divided into sham-operated group， model group， testosterone propionate group（0.2 mg·kg^-1·d^-1， intramuscular injection） and Wuzi Yanzongwan group（1.56 g·kg^-1·d^-1， intragastric administration） according to body weight， with 12 mice in each group. The right testicle and epididymis were extracted from the model group and the drug administration group to construct the semi-castrated model of low spermatogenic function， while the fur and the right scrotum of the sham-operated group were only cut and immediately sterilized and sutured. At the end of the intervention， hematoxylin-eosin（HE） staining was used to observe the histopathology of testis， enzyme-linked immunosorbent assay（ELISA） was used to detect the levels of serum testosterone（T）， luteinizing hormone（LH） and follicle stimulating hormone（FSH）. The sperm count and motility of epididymis were measured by automatic sperm detector of small animal. Transcriptomic microarray technology was used to detect the mRNA expression level of testicular tissue in each group， the transcriptome of genes related to the regulation of Wuzi Yanzongwan was screened， and three mRNAs were selected for Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） to verify the transcriptome data. Through the annotation analysis of Gene Ontology（GO） and the signaling pathway analysis of Kyoto Encyclopedia of Genes and Genomes（KEGG）， the related functions of drugs regulating transcriptome were analyzed. ResultCompared with the sham-operated group， the testicular tissue of mice in the model group showed spermatogenic injury， contraction and vacuolization of the seminiferous tubules， reduction of spermatogenic cells at all levels， widening of the interstitial space， obstruction of spermatogonial cell development and other morphological abnormalities， and serum T significantly decreased， LH significantly increased（P<0.01）， and FSH elevated but no statistically significant difference， the count and vitality of epididymal sperm significantly decreased（P<0.01）. There were 882 differentially expressed mRNAs in the testicular tissues， of which 565 were up-regulated and 317 were down-regulated. Cluster analysis showed that these differentially expressed mRNA could effectively distinguish between the sham-operated group and the model group. Compared with the model group， the damage to testicular tissue in the Wuzi Yanzongwan group was reduced， the structure of the seminiferous tubules was intact， vacuolization was reduced， and the number of spermatogenic cells at all levels was significantly increased and arranged tightly. The serum T significantly increased， LH significantly decreased（P<0.01）， and FSH decreased but the difference was not statistically significant. The count and vitality of sperm in the epididymis were significantly increased（P<0.01）. Moreover， Wuzi Yanzongwan could regulate 159 mRNA levels in the testes of semi-castrated mice， of which 32 were up-regulated and 127 were down-regulated， and the data of the transcriptome assay was verified to be reliable by Real-time PCR. GO and KEGG analysis showed that the transcriptome functions regulated by Wuzi Yanzongwan were involved in the whole cell cycle process of sperm development such as sex hormone production of interstitial cells in testis， renewal， differentiation， metabolism， apoptosis and signal transduction of spermatogenic cells， and were closely related to the biological behaviors of signaling pathways such as spermatogenic stem cell function， endoplasmic reticulum protein processing and metabolic program. ConclusionWuzi Yanzongwan can effectively improve the low spermatogenic function of semi-castrated male mice， and its mechanism may be related to the regulation of testicular transcriptional regulatory network， the synthesis of sex hormones in testicular interstitial cells， the function of spermatogenic stem cells， the whole cell cycle process of spermatogenesis， as well as the expression of endoplasmic reticulum protein processing and metabolic program related genes transcription.

By sorting out and analyzing the contents about pulse diagnosis in Tanksuqnameh, it was found that in terms of pulse theory, the book contains academic viewpoints of different periods and doctors about three portions and nine readings pulse method and nutritive qi operation law in Huang Di Nei Jing, the Cunkou pulse-taking method and the Cunguanchi theory in Nan Jing, the Renying and Qikou pulse-taking method and the three-region pulse-taking method in Mai Jing, and the seven superficies-indicating, eight interior-indicating and nine channels pulse of Mai Jue, etc.; in terms of pulse theory interpretation, multiple annotations from famous doctors are cited, and TCM basic theories and knowledge of astronomy and mathematics are applied, combined with the background of ancient Iranian medicine and local medical experience for explanation; in terms of pulse diagnosis techniques, pulse diagnosis techniques such as "three fingers determining three guan", "adjusting finger density", "floating and sinking pulse", "foot back pulse breaking life and death" were recorded in books of Nan Jing, Mai Jue, Lei Zheng Huo Ren Shu, etc.; in terms of influencing pulse factors, the male and female pulse, physical pulse, and four time pulse were recorded. Tanksuqnameh is a universal work of Persian Traditional Chinese Medicine, compiled by the author Rashid-ul-Din based on his research on Chinese culture and medical knowledge, combined with the unique customs, language and culture, and way of thinking in the Middle East region, to reorganize various pulse theories from before the Han Dynasty to the Tang and Song Dynasties in China. The publication of this book indicates that TCM pulse diagnosis had been promoted to the Middle East in the 14th century and provided valuable experience for local medical development. The author's sense of identification and research spirit towards different cultures provide a historical example for achieving cross-cultural communication between TCM and medicine in different regions. The preserved literature from the Tang and Song Dynasties in the book can provide clues for a deeper understanding of ancient pulse theory in TCM, but some details do not explain thoroughly or does not match the current clinical practice. Therefore, attention should be paid to distinguishing in research and application.

Objective:To investigate the influencing factors of the therapeutic effect of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in patients with epidermal growth factor receptor (EGFR) mutant advanced non-small cell lung cancer (NSCLC).Methods:The clinical data of 104 EGFR mutant advanced NSCLC patients who received EGFR-TKI treatment in Wuxi No.2 Hospital Affiliated to Nanjing Medical University from January 2015 to October 2019 were collected. The correlation of different types of EGFR mutation with the clinicopathological characteristics, the hematological examination results and the treatment mode of patients was analyzed. Cox proportional hazard model was used to analyze the association of the progression-free survival (PFS) time of patients receiving EGFR-TKI treatment with the different types of EGFR mutation, the clinicopathological characteristics, hematological related indexes and treatment mode. Kaplan-Meier method was used to analyze the independent influencing factors for the PFS of the stratified patients.Results:The overall disease control rate (DCR) of patients receiving EGFR-TKI treatment was 92.3% (96/104). Cox univariate analysis showed that the levels of carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), D-dimer, and previous surgical treatment history of patients receiving EGFR-TKI treatment were associated with PFS of patients (all P < 0.05). Cox multi-factor analysis showed that EGFR mutation type ( HR =2.371, 95% CI 1.298-4.332, P = 0.005), combination therapy ( HR = 0.489, 95% CI 0.245-0.978, P = 0.043) and choice of therapeutic drugs ( HR = 0.261, 95% CI 0.113-0.606, P = 0.002) were independent influencing factors for the PFS of patients receiving EGFR-TKI treatment. The PFS of EGFR 19 exon-mutant patients with advanced NSCLC was longer than that of those with EGFR 21 exon-mutant (median PFS time: 14.0 months vs.9.5 months, P<0.05); the PFS of combination of radiotherapy or chemotherapy was longer than that of EGFR-TKI single therapy (median PFS time: 15.0 months vs. 9.0 months, P<0.05), the PFS of patients receiving erlotinib was better than that of those receiving gefitinib ( P<0.05). According to EGFR mutation types, it was found that EGFR 19 exon-mutant patients receiving EGFR-TKI in first-line treatment could obtain better PFS than those who receiving EGFR-TKI in second-line and above treatment (median PFS time: 14.0 months vs. 9.5 months, P<0.05). When receiving EGFR-TKI, EGFR 19 exon-mutant patients with CA125 <85 U/ml could obtain longer PFS time than those with CA125 ≥85 U/ml (median PFS time: 14.0 months vs. 6.5 months, P<0.05). Conclusions:The therapeutic effect of EGFR-TKI in EGFR-mutant patients with advanced NSCLC is positive. EGFR 19 exon-mutant NSCLC patients with low-level CA125 receiving EGFR-TKI in first-line treatment can obtain better PFS.

Objective:To explore the associations of platelet parameters platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) with the risk for stroke in people with different blood pressure levels.Methods:All the participants were from Dongfeng-Tongji cohort, including 38 295 retired employees from Dongfeng Motor Corporation at the first follow-up survey. After excluding participants with coronary heart disease, stroke, cancer, history of platelet influential drug use and those with missed data of platelet parameters or blood pressure or lost to follow-up, finally a total of 21 294 participants were included in this study. All the participants completed baseline questionnaires, physical examinations, clinical biochemical tests, and blood sample collection. Cox proportional hazard models were used to estimate the hazard ratios ( HRs) and the corresponding 95% confident intervals ( CIs) for the associations between platelet parameters and risk for stroke in people with different blood pressure levels. Results:After a mean follow-up of 8.0 years, 1 578 participants developed incident stroke [1 266 ischemic stroke (IS) cases and 312 hemorrhagic stroke (HS) cases]. Compared with the participants with PLT<188×10 9/L, those with PLT≥188×10 9/L among hypertension cases were significantly associated with higher risks for stroke and IS (stroke: HR=1.27, 95% CI: 1.12-1.44; IS: HR=1.39, 95% CI: 1.21-1.60). Among hypertension group, compared with participants with PCT<0.165%, PCT≥0.165% were significantly associated with higher risk for stroke ( HR=1.15, 95% CI: 1.01-1.30) and lower risk for HS ( HR=0.70, 95% CI: 0.53-0.93); Among non-hypertension and hypertension group, PCT ≥0.165% were significantly associated with higher risks of IS ( HR=1.27, 95% CI: 1.05-1.54; HR=1.31, 95% CI: 1.14-1.50). MPV and PDW were not significantly associated with risk for stroke. Risk for stroke increased significantly in hypertension cases with different platelet parameters levels compared with non-hypertension cases with lower levels of each platelet parameters. Conclusion:Higher levels of PLT and PCT could increase the risks for stroke and IS in middle-aged and elderly hypertension patients, and lower levels of PCT could decrease the risk for HS in hypertension patients.

Prostate cancer is one of the malignant tumors with high incidence. Although most patients with prostate cancer respond well to standard treatment, they often have a poor prognosis once they develop hormone resistance. Radionuclide targeted therapy is an important method to treat malignant tumors after surgery and chemo-radiotherapy. New radioligand therapy (RLT), represented by 177Lu-prostate specific membrane antigen (PSMA)-RLT, effectively solves the problem of poor efficacy in advanced hormone-resistant prostate cancer, and has been widely recognized in the world. In this paper, the clinical practice of 177Lu-PSMA-RLT in the treatment of prostate cancer and its common adverse reactions are described in order to better understand and master its methods and lay the foundation for better clinical application and follow-up research.
