Diabetes is a common chronic non-infectious disease. Diabetic patients not only suffer from metabolic disorders, but are also prone to immune deficiencies and are at a higher risk of being infected with human papillomavirus (HPV). Many studies at home and abroad have shown that the HPV infection rate of patients with diabetes is higher than that of non-diabetic patients. Patients with diabetes can benefit from HPV vaccination, and the tolerance is good. HPV vaccination is recommended for diabetic patients. This article reviews the research on diabetes, HPV infection, and HPV vaccine, which will provide references for HPV vaccination in diabetic patients.

Objective:To evaluate the efficacy and prognostic factors of radiotherapy combined with immunotherapy as the first-line treatment for patients with locally advanced or metastatic esophageal squamous cell carcinoma (LA/M ESCC).Methods:A single-center, retrospective analysis was conducted for the recent efficacy, survival, prognostic factors, post-treatment failure modes, and treatment-related adverse reactions of 57 LA/M ESCC patients eligible for enrollment.Results:The entire group of patients had 1-, 2-, and 3-year overall survival (OS) of 86.0%, 57.5%, and 53.9%, respectively and 1-, 2-, and 3-year progression-free survival (PFS) of 61.4%, 31.0%, and 31.0%, respectively. The median OS was not reached, and the median PFS was 15.0 (95% CI: 10.77-19.23) months. These patients had an overall response rate (ORR) of 80.7% (46/57) and a disease control rate (DCR) of 94.7% (54/57). As indicated by the result of the multivariate analysis, the independent prognostic factors affecting the OS of the patients included their age, clinical stage, number of immunotherapy cycles, and recent efficacy ( HR = 0.25, 2.58, 0.35, 4.05, P < 0.05), and the independent factors influencing the PFS of the patients included their clinical stage and recent efficacy ( HR = 2.27, 1.97, P < 0.05). There were no statistically significant differences in the effects of irradiation ranges and the combination modes of immunologic drugs and chemoradiotherapy on both OS and PFS of the patients ( P > 0.05). A total of 32 patients suffered post-treatment failure. After the second treatment, they had 1- and 2-year OS of 55.7% and 25.3%, respectively, with median OS of 14.0 (95% CI: 5.17-22.83) months. A total of 26 cases experienced treatment-associated adverse reactions of grades 2 or higher during and after treatment. Conclusions:The combination of radiotherapy and immunotherapy is effective and safe as the first-line treatment for LA/M ESCC patients. The post-treatment failure modes still include local recurrence and distant metastasis. Therefore, such combination merits further investigation.

Objective:To analyze whether involved-field irradiation (IFI) was associated with improved survival and reduced treatment-related adverse events compared with elective nodal irradiation (ENI) in Chinese patients with esophageal squamous cell carcinoma receiving radiotherapy.Methods:Literature review was conducted from CNKI, Wanfang Data, PubMed, Embase, Web of Science and Cochrane Central databases (until July 31, 2022). Relevant data were collected according to the inclusion and exclusion criteria. Primary outcomes included overall survival (OS) rate and treatment-related adverse events. Secondary outcomes included progression-free survival (PFS) rate and local control rate (LCR). Risk of bias was assessed using the Cochrane Risk of Bias tool. The quality of the results was assessed by using the meta analysis of Evidence Evaluation and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methods.Results:A total of 7 articles with 918 patients were included of which 465 received IFI and 453 received ENI. The 1-, 2-, 3-and 5-year OS rates in the IFI group were not significantly different from those in the ENI group (1-year OS rate: RR=1.00, 95% CI=0.94-1.07, P=0.97, high certainty; 2-year OS rate: RR=1.01, 95% CI=0.90-1.13, P=0.90, high certainty; 3-year OS rate: RR=0.86, 95% CI=0.71-1.05, P=0.14, high certainty; 5-year OS rate: RR=0.76, 95% CI=0.42-1.37, P=0.36, low certainty). In the IFI group, patients with ≥grade 2 acute radiation esophagitis ( RR=0.71, 95% CI=0.58-0.87, P=0.001, high certainty), ≥grade 3 acute radiation esophagitis ( RR=0.39, 95% CI=0.24-0.64, P<0.001, high certainty) and ≥grade 2 acute radiation pneumonitis ( RR=0.72, 95% CI=0.52-0.99, P=0.04, high certainty) were significantly lower compared with those in the ENI group. However, no significant differences were observed in the incidence of ≥grade 3 late radiation esophagitis, ≥grade 3 acute radiation pneumonitis and ≥grade 3 late radiation pneumonitis between two groups. No significant differences were noted in the 1-, 2-, 3-PFS rates and LCR between two groups. Conclusions:For Chinese patients with esophageal squamous cell carcinoma, IFI and ENI yield similar efficacy in terms of OS, PFS and LCR. However, IFI has a lower incidence of ≥grade 2 acute radiation esophagitis, ≥grade 3 acute radiation esophagitis and ≥grade 2 acute radiation pneumonitis than ENI.

ObjectiveTo investigate the effects of the inoculation of potassium-solubilizing bacteria on the rhizosphere soil microenvironment of Paris polyphylla var. yunnanensis. MethodThe effects of different potassium-solubilizing bacteria on the physical and chemical properties， microbial community structure， and soil enzyme activity in the rhizosphere soil of P. polyphylla var. yunnanensis were investigated by pot planting at room temperature. The correlation of various indexes was analyzed. ResultThe inoculation with different potassium-solubilizing bacteria could significantly affect the physical and chemical properties of rhizosphere soil of P. polyphylla var. yunnanensis. The mass fractions of available nitrogen， available phosphorus， and available potassium were 24.5-90.5 mg·kg^-1， 2.53-25.9 mg·kg^-1， and 132-312 mg·kg^-1， respectively， and the soil pH was 7.08-7.75， which were in line with the optimal ranges of P. polyphylla var. yunnanensis planting. The inoculation of different potassium-solubilizing bacteria could affect the number of bacteria， actinomycetes， and fungi in rhizosphere soil to varying degrees. The transformation of soil from "fungal type" to "bacterial type" marks the improvement of soil fertility. It also affected the enzyme activity of rhizosphere soil， and the activities of neutral phosphatase， protease， and polyphenol oxidase showed an increasing trend. The correlation analysis showed that the number of bacteria was negatively correlated with the number of fungi （r=-0.856， P<0.01）， positively correlated with the number of actinomycetes， the content of available nitrogen and available potassium， and negatively correlated with soil pH. ConclusionThe inoculation of potassium-solubilizing bacteria can effectively improve the content of available potassium， available nitrogen， available phosphorus， and other nutrients in the rhizosphere soil of P. polyphylla var. yunnanensis， improve soil fertility， alleviate the continuous cropping obstacles of P. polyphylla var. yunnanensis， and lay a theoretical foundation for the green and sustainable development of P. polyphylla var. yunnanensis.

Objective:To evaluate the efficacy of target area of radical radiotherapy for inoperable esophageal carcinoma patients treated with intensity-modulated radiotherapy (IMRT).Methods:A retrospective analysis was performed on the clinical data of 564 Ⅰ-Ⅳ non-surgical esophageal cancer who received definitive intensity-modulated radiotherapy alone in our hospital from 2006 to 2015. Propensity score matching (PSM) was used to identify well-balanced patients for comparison. The Kaplan-Meier method was used to calculate local-regional failure-free survival (LRFFS), progression-free survival (PFS), overall survival (OS) rates and univariate analysis. The multivariate analysis of prognostic factors were tested by COX proportional hazard model.Results:The last follow-up time was December 2018, the median follow-up time was 99.7 (95% CI: 77.5-122.1) months. Follow-up rate was 95.9%. For the 564 patients, the 1-, 3-, 5- year LRFFS were 61.5%, 26.5%, 14.3%, PFS were 56.7%, 25.0%, 13.4%, OS were 73.0%, 31.1%, 16.8%. After PSM, for the elective-nodal irradiation (ENI) ( n=141) and involved-nodal irradiation (IFI) ( n=141) groups, the 1-, 3-, 5- year LRFFS were 68.8%, 34.2%, 19.1% vs. 65.2%, 32.1%, 17.9% ( P>0.05), PFS were 63.1%, 31.0%, 16.6% vs. 60.3%, 29.3%, 16.6% ( P>0.05), OS were 80.9%, 41.5%, 23.3% vs. 80.1%, 35.0%, 20.2% ( P>0.05). In multivariate analysis, tumor volume≤37 cm 3 and Ⅰ+ Ⅱ stage were independent factors for LRFFS, PFS and OS. Subgroup analysis showed that there were no significant differences in the survival rates between the ENI group and IFI group ( P>0.05). Comparing to the IFI group, ENI reduced the local-regional failure rate ( P=0.048). Conclusions:Using intensity-modulated radiation therapy alone for inoperable esophageal carcinoma, ENI can significantly reduce the local-regional failure rate, but not improve survival rates compared to the IFI.

Objective:To evaluate the effects of different irradiation ranges in definitive intensity-modulated radiotherapy (IMRT) combined with chemotherapy on the survival of esophageal cancer patients.Methods:Clinical data of 360 esophageal cancer patients who received definitive chemoradiotherapy in the Fourth Hospital of Hebei Medical University from 2006 to 2015 were retrospectively analyzed. Among them, 131 patients received elective nodal irradiation (ENI) and 229 patients underwent involved-field irradiation (IFI). Platinum-based chemotherapy was adopted. The overall survival (OS) rate was analyzed by Kaplan- Meier method and Logrank test. Results:Until the final follow-up at the end of December 2018, the follow-up rate was 96%. The median follow-up time was 64 months (95% CI: 53-76). The median survival time was 24 months (95% CI: 20-28). The 1-, 3-, 5-year OS rates were 76.1%, 38.7% and 21.0%, respectively. After propensity score matching, the 1-, 3-, 5-year OS rates were 83.9%, 48.6%, 26.8% vs. 74.0%, 33.8%, 17.5% between the ENI ( n=131) and IFI groups ( n=131)( P=0.011), respectively. Subgroup analysis showed that patients with male, aged≤66 years, cervical and upper-thoracic location, tumor length≤7 cm, tumor volume≤50 cm 3, T 1-3 stage, dosage>60 Gy and concurrent chemoradiotherapy obtained better OS rates in the ENI group than their counterparts in the IFI group (all P<0.05). In the ENI group, the total failure rate, locoregional failure rate and distant metastasis rate were significantly lower, whereas the incidence of ≥Grade Ⅲ myelosuppression was remarkably higher than those in the IFI group (all P<0.05). Conclusion:Compared with IFI, ENI can significantly improve the survival for patients with early-stage and cervical and upper-thoracic esophageal cancer receiving definitive IMRT combined with chemotherapy.

Objective:To explore the therapeutic efficacy and safety of elective nodal irradiation (ENI) and involved field irradiation (IFI) in intensity-modulated radiotherapy for esophageal cancer, screen the patients suitable to undergo ENI radiotherapy and provide evidences for individual treatment of esophageal cancer.Methods:A retrospective analysis was performed on the clinical data of 924 patients with esophageal cancer who received definitive intensity-modulated radiotherapy in our hospital from January 2006 to December 2015. Among them, 272 patients received ENI and the other 652 patients received IFI. The clinicopathologic characteristics of 272 cases in ENI group and 652 cases in IFI group, who were recruited according to the balance of propensity score matching method, were compared. The Kaplan-Meier method was used to calculate 1-year, 3-years and 5-years local-regional failure-free survival (LRFFS), progression-free survival (PFS) and overall survival (OS) rates. The univariate and multivariate analysis of prognostic factors were also determined by Cox proportional hazard model and Long-rank test.Results:The clinicopathologic characteristics of these two group were not significantly different ( P>0.05). The median follow-up time was 85.9 months and the follow-up rate was 95.9%. The 1-year, 3-years, 5-years PFS rates of the ENI groups were 65.3%, 31.7%, 18.4%, respectively, higher than 54.0%, 20.9%, 12.7% of the IFI group ( P=0.001). The 1-year, 3-years, 5-years OS rates of the ENI groups were 79.0%, 43.7%, 24.9%, respectively, higher than 75.0%, 31.8%, 17.2% of the IFI group ( P=0.003). In multivariate analysis, the sex, tumor volume, N stage and radiation field were independent factors for PFS and OS ( P<0.05). Subgroup analysis showed that patients with male, age≤66 year, cervical and upper-thoracic location, tumor length≤6 cm, T1-2 stage, N0-1 stage, Ⅰ-Ⅱ stage, tumor volume≤50 cm 3, dosage>60 Gy and≤2 cycles of chemotherapy in the ENI group had a better survival rate than those in the IFI group ( P<0.05). The total failure rate, local-regional failure rate in ENI group were significantly lower than those of IFI group ( P=0.001, P=0.004). The incidence of bone marrow depression≥ grade 2 and 3 in ENI group was higher than that of the IFI group ( P<0.05). However, the incidences of radioactive esophagitis≥ grade 3, radioactive pneumonia and late adverse reactions were not significantly different between these two groups ( P>0.05). Conclusion:Compared with IFI, ENI can significantly improve the long-term survival for young, early TN stage and cervical/upper-thoracic esophageal cancer patients underwent chemotherapy.

OBJECTIVE: To identify the main active components in Ⅲ and their targets and explore the mechanism by which Ⅲ alleviates proteinuria in chronic kidney disease (CKD) based on network pharmacology. METHODS: The active components of Ⅲ and their potential targets, along with the oral bioavailability and drug-like properties of each component were searched in the TCMSP database. The proteinuria-related targets were searched in the GeneCards database. The active component-target network was constructed using Cytoscape software, and the acquired information of the targets from ClueGO was used for enrichment analysis of the gene pathways. RESULTS: A total of 102 active components were identified from Ⅲ. These active components acted on 126 targets, among which 69 were related to proteinuria. Enrichment analysis revealed fluid shear stress- and atherosclerosisrelated pathways as the highly significant pathways in proteinuria associated with CKD. CONCLUSIONS We preliminarily validated the prescription of Ⅲ and obtained scientific evidence that supported its use for treatment of proteinuria in CKD. The findings in this study provide a theoretical basis for further study of the mechanism of Ⅲ in the treatment of proteinuria in CKD.
