Effects of short-term intensive insulin pump treatment on type 2 diabetes and its influencing factors / 中国临床药理学与治疗学

AIM: To observe the real world efficacy of continuous subcutaneous insulin infusion (CSII) with insulin pump in short-term intensive treatment of patients with type 2 diabetes (T2DM) and explore the influencing factors associated with efficacy. METHODS: A total of 369 hospitalized T2DM patients were treated with CSII short-term intensive therapy. Based on the blood glucose levels on the 5th day of treatment, they were divided into two groups, namely the qualified blood glucose control group and the non-qualified blood glucose control group. The differences of glucose metabolism, physiology, biochemistry and other indicators between the two groups were compared, and the influencing factors of insulin pump efficacy were analyzed by regression statistics. RESULTS: After 4 days of CSII short-term treatment, 225 patients (61%) achieved blood glucose control standards, while 144 patients (39%) did not achieve blood glucose control standards. Compared with the qualified blood glucose control group, the non-qualified blood glucose control group was older and with higher levels of total daily insulin dose per kilogram of body weight (TDD), fasting blood glucose (FBG), fasting insulin, fasting C-peptide, and insulin resistance index (HOMA-IR), while lower levels of blood phosphorus, insulin growth factor 1 (IGF1). In terms of biochemical indicators, there was no significant difference between the two groups as a whole, including blood lipid levels, liver function, and kidney function. The results of univariate regression and multivariate stepwise regression analysis showed that 2-hour postprandial insulin, TDD and blood phosphorus were the key factors influencing the efficacy of Insulin pump. Among them, qualified blood glucose control was positively correlated with blood phosphorus, and negatively correlated with 2-hour postprandial insulin and TDD. CONCLUSION: CSII with insulin pump is an ideal method for short-term intensive treatment of type 2 diabetes. In order to achieve a more satisfactory rate of qualified blood glucose control, more attention should be paid to the patient's blood phosphorus, 2-hour postprandial insulin and TDD in clinical use.

OBJECTIVE@#To assess the outcomes after acupoint application in patients with pharyngeal pain in a real-world settings, and analyze the characteristics of effective population and prescription characteristics of acupoint application.@*METHODS@#Based on CHUNBO platform, patients with pharyngeal pain who were candidates for acupoint application on the basis of physician-evaluation, were enrolled in a nationwide, prospective, 69-week multicenter observational study from August 2020 to February 2022. Propensity score matching (PSM) was used to match the confounding factors and the association rules were used to analyze the characteristics of effective population and prescription characteristics of acupoint application. Outcome assessments included the disappearance rate of pharyngeal pain (within 3, 7, and 14 days), disappearance time of pharyngeal pain, as well as adverse events.@*RESULTS@#Of 7,699 enrolled participants, 6,693 (86.9%) received acupoint application and 1,450 (21.7%) with non-acupoint application. After PSM, there were 1,004 patients each in the application group (AG) and non-application group (NAG). The disappearance rate of pharyngeal pain in the AG at 3, 7, and 14 days were all higher than those in the NAG (P<0.05). The disappearance time of pharyngeal pain in the AG were shorter than that in the NAG (logrank P<0.001, hazard ratio=1.51, 95% confidence interval: 1.41-1.63). The median age of effective cases was 4 years, mainly 3-6 years old (40.21%). The disappearance rate of pharyngeal pain in the application group with tonsil diseases was 2.19 times higher than that in the NAG (P<0.05). The commonly used acupoints for the effective cases were Tiantu (RN 22), Shenque (RN 8) and Dazhui (DU 14). The commonly used herbs for the effective cases were Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae. Among them, Natrii sulfas was applied to RN 8 most frequently (support 84.39%). A total of 1,324 (17.2%) patients experienced AEs, and mainly occurred in the AG, with significant difference in the incidence of AEs between goups (P<0.05). All AEs reported were the first grade, and the average regression days of AEs was 2.8 days.@*CONCLUSIONS@#Acupoint application in patients with pharyngeal pain resulted in improved effective rate and shortened duration, especially children aged 3-6 years old, and those with tonsil diseases. Acupoint of RN 22, RN 8 and DU 14, Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae were the most commonly used herbs in the treatment of pharyngeal pain.

Real-world practice of acute leukemia intrathecal chemotherapy administration: A Mexican nationwide survey

ABSTRACT Introduction: Intrathecal chemotherapy is a mainstay component of acute lymphoblastic leukemia treatment. In Mexico, there is a considerable practice variability in aspects, such as the manner of preparation and the administration technique. Objective: Our objective was to describe the different techniques used for the application of ITC and review the existing recommendations in the literature. Method: A cross-sectional, nationwide survey study was conducted by an electronic questionnaire sent to hematologists and oncologists in Mexico. We collected demographic data, personal experience, intrathecal chemotherapy techniques, drug preparation and postprocedural conduct. Results: We received 173 responses. Twenty percent had an anesthesiologist administering sedation and pain management. The platelet count considered safe was 50 × 109/L in 48% of the participants. In 77% (n = 133) of the cases, the conventional needle with stylet used was, 49% did not receive any added diluent in the intrathecal chemotherapy and only 42% were recommended to rest in a horizontal position for more than 30 min. Conclusion: We identified a considerable variation in the administration of intrathecal chemotherapy across the hematologists in Mexico. We discuss the implications and opportunities in reducing the variation in our setting, highlighting the unmet need to establish guidelines that should be evaluated by the Mexican professional society to produce a position paper regarding practice standardization.

Objetivo: Avaliar o impacto orçamentário do tratamento com iPARP como primeira linha de manutenção, comparado ao tratamento-padrão a partir de evidências de mundo real sob a perspectiva de um hospital público referência em oncologia no Rio de Janeiro. Métodos: Foi aplicada uma análise de impacto orçamentário para estimar a introdução das tecnologias iPARP, olaparibe e niraparibe, em comparação com o cenário referência, utilizando dados de eficácia e evidências de mundo real, e considerando os custos globais de tratamento da doença em cinco anos. Este estudo foi aprovado pelo Comitê de Ética em Pesquisa, CAAE: 95157018.9.0000.5274. Resultados: A análise demonstrou que o cenário referência apresentou um impacto orçamentário no valor de R$ 3.578.768,04 em cinco anos. No cenário alternativo, o custo incremental do olaparibe chegou a ser 23,8% maior, comparado ao niraparibe, atingindo um custo de R$ 23.736.459,20 versus R$ 18.076.951,81, respectivamente. Os parâmetros que apresentaram maior impacto nas análises para a tecnologia olaparibe foram a difusão da tecnologia e o preço do medicamento. Contudo, para o niraparibe, os parâmetros de maior impacto foram a duração do tratamento, a difusão da tecnologia e a dose utilizada, demonstrando maior suscetibilidade de variação. Conclusão: Os iPARP no tratamento de pacientes com carcinoma de ovário avançado, apesar de apresentarem custo incremental de aproximadamente R$ 23 milhões em cinco anos, apontam para uma potencial redução de custos associados à progressão da doença.

Objective: Assess the budgetary impact of treatment with iPARP as a first line of maintenance, compared to standard treatment based on real-world evidence from the perspective of a public hospital reference in oncology at Rio de Janeiro. Methods: A budget impact analysis was applied to estimate the introduction of iPARP, olaparib and niraparib technologies, compared to the reference scenario, using efficacy data and real-world evidence, and considering the global costs of treating the disease in five years. This study was approved by the Research Ethics Committee, CAAE: 95157018.9.0000.5274. Results: The analysis showed that the reference scenario presented a budgetary impact of R$ 3,578,768.04 in five years. In the alternative scenario, the incremental cost of olaparib reached 23.8% higher compared to niraparib, reaching a cost of R$ 23,736,459.20 versus R$ 18,076,951.81, respectively. The parameters that had the greatest impact on the analyzes for the olaparib technology were technology diffusion and drug price. However, for niraparib, the parameters with the greatest impact were the duration of treatment, the diffusion of the technology and the dose used, demonstrating greater susceptibility to variation. Conclusion: iPARP in the treatment of patients with advanced ovarian carcinoma, despite having an incremental cost of approximately R$ 23 million in five years, point to a potential reduction in costs associated with disease progression.

Protection of inactivated vaccine against SARS-CoV-2 infections in patients with comorbidities: a prospective cohort study / 医学前沿

Protection against severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection of inactivated vaccines is not well characterized in people with comorbidities, who are at high risk of severe infection. We compared the risk of SARS-CoV-2 infection after complete vaccination with Sinopharm/BBIBP in people with comorbidities (e.g., autoimmune diseases, cardiovascular disease, chronic lung disease, and diabetes) with healthy individuals using a Cox-proportional hazard model. In July-September 2021, a total of 10 548 people (comorbidities, 2143; healthy, 8405) receiving the complete primary series of vaccination with Sinopharm/BBIBP in Bangkok, Thailand were prospectively followed for SARS-CoV-2 infection through text messaging and telephone interviewing for 6 months. A total of 295 infections from 284 participants were found. HRs (95% CI) of individuals with any comorbidities did not increase (unadjusted, 1.02 (0.77-1.36), P = 0.89; adjusted, 1.04 (0.78-1.38), P = 0.81). HRs significantly increased in the subgroup of autoimmune diseases (unadjusted, 2.64 (1.09-6.38), P = 0.032; adjusted, 4.45 (1.83-10.83), P = 0.001) but not in cardiovascular disease, chronic lung disease, or diabetes. The protection against SARS-CoV-2 infection of the Sinopharm vaccine was similar in participants with any comorbidities vs. healthy individuals. However, the protection appeared lower in the subgroup of autoimmune diseases, which may reflect suboptimal immune responses among these people.

Clinical Study of Osteoking Combined with Non-Steroidal Anti-inflammatory Drugs in Treatment of Knee Osteoarthritis / 中国实验方剂学杂志

ObjectiveTo explore the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis based on real-world data and provide a basis for clinical medication. MethodFrom May 2020 to December 2021， the data of a total of 1 002 patients with knee osteoarthritis who did not undergo knee joint replacement surgery was collected through the registration method. 952 patients were ultimately included， including 133 cases orally taking Osteoking combined with non-steroidal anti-inflammatory drugs as the observation group and 73 cases orally taking non-steroidal anti-inflammatory drugs alone as the control group. Statistical analysis was conducted on the baseline data， VAS scores， WOMAC scores， and other items. The visit point is the 4th and 8th weeks after registration. In order to further elucidate the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis， the effective components of Osteoking and the relevant gene sets of non-steroidal anti-inflammatory drugs and knee osteoarthritis were obtained through network pharmacology methods and retrieval in bone injury cross database， TCMSP， and other databases. Venn analysis was performed on the relevant gene sets， and a PPI network diagram was constructed. Then key core targets were screened out， and enrichment GO and KEGG enrichment analyses were conducted. ResultThe VAS score of the observation group decreases by an average of （-2.79±1.206） scores in the 4th week， which is better than the control group ［（-2.73±1.575） scores， P<0.05］. The VAS score of the observation group decreases by an average of （-3.97±1.308） scores in the 8th week， which is better than the control group ［（-3.89±1.822） scores， P<0.05］. The total WOMAC score of the observation group decreases by an average of （-52.07±21.677） scores points in the 8th week， which is significantly better than the control group ［（-46.75±25.368） scores， P<0.05］. The observation group has an average decrease of （-10.99±4.229） scores in WOMAC （pain） score in the 8th week， which is better than the control group ［（-10.03±5.535） scores， P<0.05］. The observation group has an average decrease of （-1.49±2.901） in WOMAC （stiffness） score in the 4th week， which is better than the control group ［（-0.92±1.998） scores， P<0.05］， and the observation group has an average decrease of （-1.90±3.200） scores in WOMAC （stiffness） score in the 8th week， which is better than the control group ［（-1.26±2.230） scores， P<0.05］. The observation group shows an average decrease of （-39.17±16.562） scores in WOMAC （joint function） score in the 8th week， which is significantly better than the control group ［（-35.47±20.098） scores， P<0.05］. According to network pharmacology analysis， the core network target of Osteoking in treating knee osteoarthritis is manifested as regulating signal pathways such as signal transduction transcription activator 3（STAT3）， vascular endothelial growth factor A（VEGFA）， tumor necrosis factor （TNF） to regulate cell signaling， angiogenesis， chondrocyte proliferation and migration， and inflammatory cells， thereby inhibiting inflammatory reactions， reducing damage， and delaying the development of the disease. ConclusionAfter a 4-week and 8-week course of treatment for knee osteoarthritis with Osteoking combined with non-steroidal anti-inflammatory drugs， there is a significant therapeutic effect on relieving pain and joint stiffness and improving joint function. In network pharmacology， Osteoking is involved in regulating inflammatory factors， metabolic response-related biological processes， the proliferation and apoptosis of chondrocytes， etc. in the treatment of knee osteoarthritis， resulting in anti-inflammatory and analgesic effects and improving joint mobility and joint stiffness. Therefore， it is worthy of clinical promotion and application.

Clinical Efficacy and Mechanism of Osteoking in Treatment of Knee Osteoarthritis Based on Real-world Data / 中国实验方剂学杂志

ObjectiveTo investigate the clinical efficacy and mechanisms of Osteoking in the treatment of knee osteoarthritis （KOA） in real-world practice， so as to provide a basis for the rational clinical use of Osteoking. MethodFrom the Osteoking for knee osteoarthritis case registration system， 638 KOA cases treated with Osteoking were selected and analyzed in SPSS 26.0. The clinical data were collected from 20 hospitals in China from May 2020 to December 2021. Descriptive analyses of patient age， gender， body mass index， course of treatment and other parameters were performed. The Mann-Whitney U test was performed to compare the visual analogue scale （VAS） and Western Ontario and McMaster universities arthritis index （WOMAC） scores before and after treatment. The integrative pharmacology-based research platform of traditional Chinese medicine （TCMIP） v2.0 was used for network analysis of the core targets of Osteoking in treating knee osteoarthritis. Furthermore， 20 KOA patients treated with Osteoking in the Third Affiliated Hospital of Beijing University of Chinese Medicine from October to December in 2022 were enrolled in the treatment group， and 20 healthy volunteers in the control group. The enzyme-linked immunosorbent assay was employed to measure the serum levels of related indicators to verify the prediction results. ResultA total of 638 KOA patients were treated with Osteoking， including 429 （67.24%） receiving Osteoking alone and 209 （32.76%） receiving Osteoking combined with other therapies. The female patients （415， 65.05%） were more than the male patients （223， 34.95%）. The patients showed the mean age of （63.48±13.51） years， mean body mass index of （24.09±2.98） kg·m-2， and mean course of treatment of （15.78±9.66） days. Most of the patients were rated as grades Ⅱ （46.24%） and Ⅲ （34.64%） in Kellgren-Lawrence （K-L） grading and in the relief stage （82.45%） in clinical staging. There was no significant correlation between clinical staging and K-L grading results. The cluster analysis identified three TCM syndromes： Qi stagnation and blood stasis， cold-dampness obstruction， and liver-kidney deficiency. The overall clinical efficacy evaluation showed that VAS score decreased from （6.01±0.85） scores before treatment to （2.54±1.73） scores after treatment （P<0.05）， and the WOMAC score decreased from （93.25±25.91） scores before treatment to （50.73±25.14） scores after treatment （P<0.05）. The network analysis predicted that Osteoking might regulate the transforming growth factor-beta （TGF-β）， tumor necrosis factor-alpha （TNF-α）， and nuclear factor-kappa B （NF-κB） signaling pathways to exert the therapeutic effect. The clinical trial showed elevated TGF-β1 level （P<0.01） and lowered NF-κB subunit RELA and tumor necrosis factor receptor superfamily， member 1A （TNFRSF1A） levels （P<0.05） after treatment. The synergistic effects of these changes provide a multidimensional and comprehensive therapeutic efficacy for KOA， alleviating the joint pain and limited mobility in patients. ConclusionOsteoking showed significant therapeutic efficacy in treating KOA. Osteoking may act on multiple pathways involved in cartilage metabolism and inflammation. The findings provide experimental evidence and theoretical support for elucidating the multi-target mechanism of Osteoking in treating KOA.

Evaluation of Screening Model for Advanced Colorectal Adenoma and Traditional Chinese Medicine Tongue Image Analysis Based on Real World Data / 中医杂志

ObjectiveTo evaluate the effectiveness and consistency of three commonly used early colorectal cancer screening models for advanced colorectal adenoma as a noninvasive means， and to assess the predictive value of traditional Chinese medicine （TCM） tongue images in the models. MethodsPatients diagnosed with colorectal adenoma who underwent colonoscopy and pathological examination were selected as the study participants. Basic clinical data and tongue image were collected. The prediction models of Asia-Pacific colorectal screening （APCS） model， its revision （M-APCS） and colorectal neoplasia predict （CNP） model were applied to compare the predictive effects of the three models on advanced stage adenomas of the colon， the differences in clinical data and traditional Chinese medicine tongue characteristics among patients with different degrees of adenomas， and the similarities and differences in tongue characteristics among the models. The discriminative ability of the three risk models was evaluated using the area under the curve （AUC） and receiver operating characteristic （ROC） curves. The calibration was assessed using the Kuder-Richardson coefficient and the Hosmer-Lemeshow test for consistency analysis. ResultsA total of 227 patients with adenoma were analyzed， including 104 patients （45.82%） with advanced adenoma. In the detection of advanced adenoma， those with greasy coating （70 cases， 67.3%） were higher than those without greasy coating （34 cases， 32.7%， P＜0.05）. After multivariate analysis， the odds ratio （OR） value of non-greasy coating was 0.371 （0.204~0.673， P＜0.01）， indicating that non-greasy coating was a protective factor for advanced adenomas. Among the three risk models， the detection rate of advanced adenoma in the high-risk group with APCS was the highest （63.3%）， which was 1.49 times and 2.04 times that of the medium-risk group （42.6%） and the low-risk group （31.1%， P＜0.01）. The detection rate of advanced adenomas in high-risk groups of M-APCS and CNP was slightly higher than that in moderate or low risk groups （P＞0.05）. The proportion of yellow and greasy coating in high-risk group was higher than that in the medium-risk or low-risk group （P＜0.05）. For the ability to distinguish advanced and non-advanced adenomas， the AUC of APCS was 0.629 （95% CI： 0.556~0.702） and was higher than that of M-APCS （0.591） and CNP （0.586）. In calibration evaluation， Cronbach's alpha was 0.919 （＞0.7）， which indicated that the three models were consistent. In the correlation matrix， the correlation coefficients between APCS model and M-APCS model， and CNP model were 0.794 and 0.717， respectively， and the correlation coefficients between M-APCS model and CNP model were 0.873， Hosmer-Lemeshow χ2 =2.552， P＞0.05， which suggested that the three models had good calibration ability. ConclusionAll three models demonstrate the efficiency to identify advanced colorectal adenoma， and their calibration ability is considered to be good. Among the three models， the APCS exhibits the highest recognition efficiency， however， the recognition accuracy of the APCS model needs improvement. The presence of a greasy coating is identified as one of the potential predictors of advanced adenoma. Consequently， it can be considered for inclusion in the risk model of advanced colorectal adenoma to enhance the accuracy.

Research Ideas and Challenge of Real World Study and Artificial Intelligence Based On Clinical Diagnosis and Treatment Data of Traditional Chinese Medicine / 中医杂志

With the continuous progress of research methodology in the real world and the growing maturity of artificial intelligence technology， a method for conducting “quantitative” research to guide clinical practice based on traditional Chinese medicine （TCM） diagnosis and treatment data was gradually developed. However， there is still a need for further improvements in the overall design of studies and the transformation of findings into clinical practice. Based on this， we put forward a comprehensive overall design concept and application approach for real-world study and artificial intelligence research based on clinical diagnosis and treatment data of TCM. This approach consists of five steps： Constructing a research-based database with a large sample size and high data quality； Mining and classification of core prescriptions； Conducting cohort studies to evaluate the effectiveness of core prescriptions； Utilizing case-control studies to clarify the dominant population； Establishing predictive models to achieve precision medicine. Additionally， it is imperative for researchers to establish a standardized system for collecting TCM variables and processing data， optimize the determination and measurement methods of confounding factors， further improve and promote methodologies， and strengthen the training of interdisciplinary talents. By following this research method， we anticipate that the clinical translation of research findings will be facilitated， leading to advancements in TCM precision medicine. Real-world study and artificial intelligence research share similar research foundations， and clinical applications complement each other. In the future， the two will merge together.

Objective:To compare and analyze the application of anti-vascular endothelial growth factor (VEGF) drugs for intravitreal injection in the real world before and after the establishment of one-stop intravitreal injection center, as well as the advantages and disadvantages of different management modes.Methods:A retrospective clinical study. A total of 4 015 patients (4 659 eyes) who received anti-VEGF drugs for ocular fundus diseases at the Tianjin Medical University Eye Hospital from July, 2018 to June, 2022 were included in the study. There were 2 146 males and 1 869 females. The ocular fundus diseases in this study were as follows: 1 090 eyes of 968 patients with wet age-related macular degeneration (wAMD); 855 eyes of 654 patients with diabetic macular edema (DME); 1 158 eyes of 980 patients with diabetic retinopathy (DR); 930 eyes of 916 patients with macular edema secondary to retinal vein occlusion (RVO-ME). A total of 294 eyes of 275 patients with choroidal neovascularization secondary to pathological myopia (PM-CNV); 332 eyes of 222 patients with other fundus diseases. A total of 13 796 anti-VEGF needles were injected. A total of 1 252 patients (1 403 eyes) from July 2018 to June 2020 were regarded as the control group. From July 2020 to June 2022, 2 763 patients (3 256 eyes) who received anti-VEGF treatment in the intravitreal injection center were regarded as the observation group. The total number of intravitreal injection needles, the distribution of anti-VEGF therapy in each disease according to disease classification, the proportion of patients who chose the 3+ on-demand treatment (PRN) regimen and the distribution of clinical application of different anti-VEGF drugs were compared between the control group and the observation group. The waiting time and medical experience of patients were investigated by questionnaire. χ2 test was used to compare the count data between the two groups, and t test was used to compare the measurement data. Results:Among the 13 796 anti-VEGF injections in 4 659 eyes, the total number of anti-VEGF drugs used in the control and observation groups were 4 762 and 9 034, respectively, with an average of (3.39±3.78) and (2.78±2.27) injections per eye ( t=6.900, P<0.001), respectively. In the control and observation groups, a total of 1 728 and 2 705 injections of anti-VEGF drugs were used for wAMD with an average of (5.14±4.56) and (3.59±2.45) injections per eye, respectively; a total of 982 and 2 038 injections of anti-VEGF drugs were used for DME with an average of (4.36±4.91) and (3.24±2.77) needles per eye, respectively. Additionally, a total of 942 and 2 179 injections of anti-VEGF drugs were injected for RVO-ME with an average of (3.98±3.71) and (3.14±2.15) injections per eye, respectively; a total of 291 and 615 injections of anti-VEGF drugs were injected for PM-CNV with an average of (3.31±2.63) and (2.99±1.69) injections per eye, respectively. A total of 683 and 1 029 injections of anti-VEGF drugs were injected for DR with an average of (1.60±1.26) and (1.41±1.05) injections per eye, respectively. The clinical application and implementation of "3+PRN" treatment were as follows: 223 (66.4%, 223/336) and 431 eyes (57.2%, 431/754) in the wAMD ( χ2=8.210, P=0.004), 75 (33.3%, 75/225) and 236 (37.5%, 236/630) eyes in the DME ( χ2=1.220, P>0.05), and 97 (40.9%, 97/237) and 355 eyes (51.2%, 355/693) in the RVO-ME ( χ2=7.498, P=0.006), 39 (44.3%, 39/88) and 111 eyes (53.9%, 111/206) in the PM-CNV ( χ2=2.258, P>0.05), respectively. In addition, the results of the questionnaire survey showed that there were significant differences between the control and observation groups regarding the time of appointment waiting for surgery ( t=1.340), time from admission to entering the operating room on the day of injection ( t=2.780), time from completing preoperative treatment preparation to waiting for entering the operating room ( t=8.390), and time from admission to discharge ( t=6.060) ( P<0.05). Conclusions:The establishment of a one-stop intravitreal injection mode greatly improved work efficiency and increased the number of injections. At the same time, the compliance, waiting time, and overall medical experience of patients significantly improved under centralized management.

Effectiveness of HPV vaccines in real-world study / 中华微生物学和免疫学杂志

Human papillomavirus (HPV) is an epitheliotropic virus. High-risk HPV infections lead to precancerous lesions which may progress to cancer in the cervix, vagina and vulva, while low-risk HPV infections cause benign lesions such as genital warts and recurrent respiratory papillomas. HPV infection remains one of the major public health problems threatening human health. To date, six prophylactic preventive HPV vaccines have been licensed, and the effectiveness of HPV vaccination has gradually appeared in some countries with earlier vaccination. HPV vaccination has been proved to be effective in protecting against diseases related to HPV infection, which leads to significant reductions in the incidence of vaccine-type HPV-related infection, high cervical lesions, anogenital warts, recurrent respiratory papillomatosis and other relevant diseases. The herd protection effect of the vaccines is outstanding. Meanwhile, a bivalent HPV vaccine has been demonstrated for the cross-protection against HPV infections of non-vaccine types (HPV31/33/45) in real-world vaccination practice.

Safety and efficacy of Rezūm water vapor thermal therapy system in the treatment of benign prostatic hyperplasia / 中华泌尿外科杂志

Objective:To evaluate the efficacy and safety of Rezūm Water Vapor Thermal Therapy system in the treatment of patients with benign prostatic hyperplasia (BPH).Methods:The clinical data of 22 patients with benign prostatic hyperplasia treated with Rezūm Water Vapor Thermal Therapy system in Boao Yiling Life Care Center in Hainan from December 2020 to January 2021 were retrospectively analyzed, with age of (61.0±5.9) years, prostate volume of (43.7±8.4) ml. international prostate symptom score (IPSS) of (19.3±3.7), quality of life (QOL) score of (4.2±0.8), maximum urinary flow rate (Q max) of (11.9±3.4) ml ml/s, and residual urine volume (PVR) of (14.0±19.0). For 19 patients with sexual life, the International Index of Erectile Function Questionnaire-5 (IIEF-5) were 17.0±5.5, the Men's Sexual Health Questionnaire-Ejaculatory Dysfunction Score (MSHQ-EjD) ejaculatory function score were 10.0±3.2, and the ejaculatory satisfaction score were 1.5±1.0. Twenty-two patients underwent Rezūm Water Vapor Thermal Therapy under intravenous anesthesia (general anesthesia without intubation) in the dorsal lithotomy position. The Rezūm system consisted of reusable thermal steam treatment device and disposable prostate thermal steam treatment instrument. The thermal steam treatment device used radiofrequency energy to heat sterile distilled water, generating high-temperature steam at 103℃. In a 9-second timeframe, the tissue temperature within each treatment area was raised approximately 70℃, causing cell death and resulting in a shrink in prostate tissue volume. The disposable prostate thermal steam treatment instrument could be inserted through a cystoscope and had a retractable needle tip that extends to a length of 10.25 mm. The needle tip had 12 evenly distributed holes arranged in three rows of four holes each, with a spacing of 120° between rows, allowing for even diffusion of thermal steam along the circumference. The patient was placed in a lithotomy position, and the disposable prostate thermal steam treatment instrument was used to examine the prostate, urethra, and bladder via cystoscopy, assessing the lateral lobes and median lobe of the prostate. The tissue spacing within each field of view of the treatment instrument is 0.5 cm, and the distance from the bladder neck to the verumontanum is calculated. The first needle was injected at 3 o’clock along the left lobe, withdrawing 2 fields of view each time. During the release of thermal steam, the needle tip was positioned perpendicular to the prostate urethral mucosa, and each needle injection delivered 0.42 ml of sterile distilled water-formed thermal steam into the prostate tissue. The thermal steam injection lasted for 9 seconds, followed by a 2-3 seconds waiting period before retracting the needle tip. One needle was injected per 2 fields of view, progressing towards the proximal urethra of the verumontanum. The same method was used to treat the right lobe. For cases with significant median lobe enlargement, two fields of view were retracted at the bladder neck, and the needle was inserted at a 45° angle. The second needle was injected at intervals determined by the extent of median lobe enlargement. Each puncture point was observed for no significant bleeding, and the instrument was then removed, with an F16/F18 silicone catheter left in place. The operative time as well as indwelling catheter time were recorded. The clinical parameters such as IPSS, QOL, prostate volume, Qmax, PVR, QOL, IIEF-5 and MSHQ-EjD at preoperative and 12 to 22 weeks post operation were compared. Adverse events from the Rezūm procedure to 12-22 weeks postoperatively were recorded. Results:All the operations were successfully completed. The operation time of Rezūm system was 3.9±1.6 min, and the indwelling catheter time after operation was 4.8±1.1 days. The IPSS scores of 22 patients at 12-22 weeks after operation were 4.4±3.3, whose reduction was 14.9±4.4 compared with these at baseline( P<0.01). The PV was (37.7±8.4)ml, Qmax was (25.5±9.6)ml/s, PVR was (6.2±8.1)ml, and QOL was 1.6±0.9, all demonstrating statistically significant differences compared to preoperative values ( P<0.05). Among the 19 cases with sexual activity, the IIEF-5 score was 20.4±3.2, and the ejaculatory function score of MSHQ-EjD was 13.1±3.1, both showing statistically significant differences compared to preoperative scores ( P<0.05). The ejaculatory satisfaction score of MSHQ-EjD was 1.1±0.5, and there was no statistically significant difference compared to preoperative scores ( P>0.05). None of the 22 cases required medication or further surgical treatment for BPH after surgery. There were no urethral injuries, rectal or bladder perforations during the surgeries, and no severe complications such as rectal fistula or bladder neck contracture occurred postoperatively. There were no deaths reported. Postoperative discomfort in the urethra occurred in 19 cases, urethral pain in 8 cases, hematuria in 15 cases, poor sleep quality in 2 cases, and constipation in 1 case, all of which resolved within 7 to 10 days after surgery. Erectile dysfunction and retrograde ejaculation occurred in one case each at 4 to 5 weeks postoperatively but did not reoccur thereafter. Prostatitis and nodular hyperplasia of the middle lobe of the prostate occurred in one case each at 21 weeks and 25 weeks postoperatively, respectively, and no treatment was administered. Conclusions:In the real world, the short-term overall effect of Rezūm Water Vapor Thermal Therapy system in the treatment of benign prostatic hyperplasia is satisfactory, which shows good efficacy and safety.

Clinical Efficacy of Dingkundan in Treatment of Ovulatory Disorder Infertility Based on Real-world / 中国实验方剂学杂志

ObjectiveTo explore the clinical efficacy of Dingkundan in the treatment of ovulation disorder infertility based on the real world and provide reliable evidence-based medical support for clinical practice. MethodClinical diagnosis and treatment data of patients with ovulation disorder infertility in the real world were collected through the Medroad Cloud system. Patients were grouped according to their real-world treatments， and the total effective rate， ovulation rate per cycle， number of days of follicle development， gonadotropin （Gn） dosage， levels of mature follicle-related hormones， endometrial thickness and classification， pregnancy rate per cycle， clinical pregnancy rate， ectopic pregnancy rate， and early pregnancy loss rate were observed. ResultA total of 207 patients were included， and the most common traditional Chinese medicine （TCM） syndrome in the entire population was liver depression and kidney deficiency. The patients were divided into a Chinese medicine group （Dingkundan， 60 cases）， a western medicine group （ovulation induction， 51 cases）， and a combination group （Dingkundan + ovulation induction， 96 cases）. The combination group（98.96%，95/96） had the highest total effective rate， which was statistically significant when compared with the Chinese medicine group（88.33%，53/60） （χ2=8.328， P<0.05）. The mature follicle estradiol （E2） and luteinizing hormone （LH） levels were the highest in the combination group， and there were statistically significant differences when compared with the western medicine group （P<0.01）. The endometrial thickness was higher in the Chinese medicine group and the combination group than in the western medicine group （P<0.01）. The proportion of type A endometrium was highest in the combination group（85.90%，201/234）， and there was a statistically significant difference when compared with the western medicine group（73.81%，93/126） （χ2=7.993， P<0.01）. The clinical pregnancy rate was 60.42%（58/96） in the combination group， which was higher than 36.67%（22/60） in the Chinese medicine group （χ2=8.336， P<0.01） and 39.22%（20/51） in the western medicine group （χ2=6.011， P<0.05）. Compared with the western medicine group， the combination group showed a favorable trend in total effective rate， ovulation rate per cycle， number of days of follicle development， Gn dosage， pregnancy rate per cycle， ectopic pregnancy rate， and early pregnancy loss rate， but the differences were not statistically significant. ConclusionIn real-world clinical practice， the combination of Dingkundan with ovulation induction can increase endometrial thickness， improve the proportion of type A endometrium， enhance egg quality， and increase the clinical pregnancy rate in patients with ovulation disorder infertility. This approach deserves further clinical research and application.

Effects of acupuncture on hemorrhagic transformation and motor function in stroke patients after intravenous thrombolysis with rt-PA: a prospective cohort study / 中国针灸

OBJECTIVE@#To observe the effects of the Xingnao Kaiqiao (regaining consciousness and opening orifices) acupuncture on hemorrhagic transformation and limb motor function after intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in stroke patients.@*METHODS@#A total of 130 stroke patients after rt-PA thrombolytic were divided into an acupuncture group (58 cases, 1 case dropped off) and a non-acupuncture group (72 cases, 7 cases dropped off) according to whether they received acupuncture treatment. Propensity score matching (PSM) was used to match each group, with 38 patients in each group. The patients in the non-acupuncture group received rt-PA thrombolytic therapy and western medical basic treatment. In addition to the basic treatment, the patients in the acupuncture group received Xingnao Kaiqiao acupuncture at Shuigou (GV 26), bilateral Neiguan (PC 6), and ipsilateral Sanyinjiao (SP 6), Chize (LU 5), once a day for 14 days. The incidence of hemorrhagic transformation within 30 days after onset was compared between the two groups. The Fugl-Meyer assessment (FMA) score and activities of daily living (ADL) score were observed at baseline and 30 days, 6 months, 1 year after onset in the two groups. The disability rate at 6 months and 1 year after onset was recorded, and safety was evaluated in both groups.@*RESULTS@#The incidence of hemorrhagic transformation in the acupuncture group was 5.3% (2/38), which was lower than 21.1% (8/38) in the non-acupuncture group (P<0.05). At 30 days, 6 month, and 1 year after onset, the FMA and ADL scores of both groups were higher than those at baseline (P<0.01), and the scores in the acupuncture group were higher than those in the non-acupuncture group (P<0.01). The disability rate in the acupuncture group at 1 year after onset was 10.5% (4/38), which was lower than 28.9% (11/38) in the non-acupuncture group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05).@*CONCLUSION@#The Xingnao Kaiqiao acupuncture method could reduce the incidence of hemorrhagic transformation in stroke patients after intravenous thrombolysis with rt-PA, improve their motor function and daily living ability, and reduce the long-term disability rate.
