RESUMO
PURPOSE: This study aimed to investigate the safety and efficacy of High-Intensity Focused Ultrasound (HIFU) treatment for vaginal intraepithelial neoplasia(VaIN). METHODS: Retrospective analysis was conducted on clinical, pathological, and follow-up data of 43 patients who underwent HIFU treatment for VaIN at Xiangya Third Hospital of Central South University between January 2018 and December 2022. The preliminary efficacy and safety of HIFU in treating VaIN were discussed. RESULTS: The 36 patients were analyzed, and the average age was 50.09 ± 12.06 years, including 24 patients with VaIN I and 12 patients with VaIN II. Five cases had a history of hysterectomy (4 due to cervical lesions, 1 due to hysteromyoma), and 2 cases had conization of cervical intraepithelial lesions (CIN). All 36 cases were complicated by human papillomavirus (HPV) infection, with 3 cases also having grade I-II CIN and undergoing cervical HIFU treatment. All patients successfully completed the HIFU treatment, with an average treatment time of 5.99 ± 1.25 min, treatment power of 3.5 W, and average total treatment dose of 1118.99 ± 316.20 J. Patients tolerated the treatment well, experiencing only slight pain with VAS score of 3. There was a mild postoperative burning sensation, which resolved within approximately 10-20 min. After 6 follow-up visits, 33 patients (91.66%) achieved cure, 1 patient (2.77%) showed persistence, 2 patients (5.55%) exhibited progression, and 27 patients (75%) tested negative for HPV. At 12 months of follow-up, the results were consistent with those of 6 months. No complications occurred during the procedure and the follow-up period. CONCLUSION: HIFU is a safe and effective treatment for VaIN. However, this study had a small sample size, a relatively short follow-up period, and lacked a control group, requiring further investigation.

BACKGROUND: Early catheter failure is the main reason for peritoneal dialysis (PD) failure, which often causes patients to withdraw from PD. Reducing the early catheter failure is critical to increase the acceptance of PD. The purpose of our study was to establish a risk stratification model to minimize early catheter failure. METHODS: A retrospective study with patients underwent PD catheter placement from January 2013 to March 2022 was conducted. The primary outcome event was early catheter failure. Univariate and multivariable logistic regression were performed to select potential risk predictors. A risk stratification model and a clinical procedure were established. The effectiveness of the model was evaluated by external validation. RESULTS: A total of 432 patients were finally enrolled in the study. The risk for early catheter failure was associated with younger age (odds ratio [OR], 0.930; 95% confidence interval [95% CI], 0.884 to 0.972; p = 0.002), lower body mass index (BMI) (OR, 0.797; 95% CI, 0.629 to 0.964; p = 0.036), and lower albumin (ALB) levels (OR, 0.881; 95% CI, 0.782 to 0.985; p = 0.036). The risk stratification model was established and performed great discrimination capability with AUC of 0.832 (cut-off value: 0.061, sensitivity: 0.853, specificity: 0.812). The model proved to be effective in external validation; the rate of early catheter failure was dropped off from 4.1% to 0%. CONCLUSIONS: We established an effective risk stratification model, by which patients with high risk of early catheter failure could be precisely identified. The clinical procedure based on the model was proved to be helpful to minimize early catheter failure.
RESUMO
Context: Shunfa Jiao, the founder of the major school of scalp acupuncture (SA), and several other authors, have speculated that SA can effectively treat diseases or disorders through needling of the external scalp zones projected from the cerebral cortex's internal function zones that are directly underneath. Objective: The review intended to analyze and discuss the historical development of Jiao's SA system, the composition of Jiao's SA stimulation zones, and the projection of the cerebral cortex's function zones on the scalp, to correct the shortcomings and inaccuracies of Jiao's hypothesis and accelerate the development of SA and its clinical application based on solid evidence. Design: The research team performed a narrative review based on the literature currently available. The research team searched PubMed, Cochrane, Webscience, CNKI (China National Knowledge Infrastructure), Wangfang, Google Scholar and Baidu Scholar databases. The search used the keywords: "Scalp acupuncture, head acupuncture, Jiao Shunfa, functional zone of cerebral cortex, history" in both English and Chinese. Setting: The study was conducted in Shanghai Bailing Tianshou Clinic of Chinese Medicine, Shanghai, People's Republic of China, and McLean Center for Complementary and Alternative Medicine, Vienna, VA, USA. Results: The nineteen stimulation zones in Jiao's SA system are actually a mixture of Jiao's speculation on SA and other authors' clinical experiences, and are confusing. The five zones on the forehead and the nasopharyngeal-mouth-tongue, madness control, spirit-emotional zones as well as the balance zone, chore-tremor control zone, and vascular movement center-more than 57% of the zones-aren't related to the projection on the scalp of the cerebral cortex's function zones directly underneath. Jiao didn't discover the five zones on the forehead through his findings of acupuncture-sensation transmission to organs, but rather Yunpeng Fang identified them in his study of SA. The nasopharyngeal-mouth-tongue, madness control, spirit-emotional zones are also others' finding. Jiao's projection of the cerebral cortex's function zones on the scalp was merely an adoption of a series of brain-surgery marks that surgeons draw before neurosurgery, which correlate external skull locations with underlying cortical areas. That Jiao believed that needling those lines could treat cerebrovascular diseases or disorders was an unfounded guess on his part. In fact, the effects of stimulating such functional zones to treat such diseases that Jiao found weren't ideal. Furthermore, Jiao's SA system has nothing to do with the integration of Chinese and Western medicine. Conclusion: Scientific evidence hasn't confirmed Jiao's hypothesis nor has that hypothesis followed from the development of neuroscience. Jiao insistence on his hypothesis seriously hindered the research and development of SA therapy. Clinical trials and experimental studies on acupuncture, especially using an fMRI, are warranted to evaluate SA's therapeutic value and to identify the functional changes of various parts of the brain that acupuncture on the scalp can cause.

BACKGROUND: Patients with gynecologic cancer receiving chemotherapy often report unmet supportive care needs. Compared with traditional face-to-face clinical interventions, mobile health can increase access to supportive care and may address patients' needs. Although app-based support programs have been developed to support patients with gynecologic cancer, their efficacy has not been adequately tested. OBJECTIVE: The aim of this study was to examine the efficacy of a mobile app for gynecologic cancer support (MGCS) for patients with gynecologic cancer receiving chemotherapy in China. METHODS: A multicenter randomized controlled trial was conducted in 2 university-affiliated hospitals in China. A total of 168 Chinese patients with gynecologic cancer were recruited and randomized to receive routine care or MGCS program plus routine care for 24 weeks. The Mishel uncertainty in illness theory guided the development of MGCS program, which has 4 modules: weekly topics, emotional care, discussion center, and health consultation. The primary outcome of this program was the assessment of the uncertainty in illness. The secondary outcomes were quality of life, symptom distress, and social support. All health outcomes were evaluated at baseline (T0), 12 weeks (T1), and 24 weeks (T2). Repeated measures analysis of covariance was used to assess the efficacy of the MGCS program. RESULTS: In this trial, 67 patients in the control group and 69 patients in the intervention group completed 2 follow-up assessments (response rate, 136/168, 81%). At 12 weeks, no significant differences were observed in any of the health outcomes between the 2 groups. At 24 weeks, compared to patients in the control group, those in the intervention group reported significant decreased uncertainty in illness (P<.001; d=-0.60; adjusted mean difference -7.69, 95% CI -11.31 to -4.07) and improved quality of life (P=.04; d=0.30; adjusted mean difference 4.77, 95% CI 0.12-9.41). CONCLUSIONS: The MGCS program demonstrated efficacy in supporting patients with gynecologic cancer receiving chemotherapy. This trial illustrates that an app-based program can be incorporated into routine care to support patients with cancer and suggests that allocation of more resources (grants, manpower, etc) to mobile health in clinics is warranted.

Our objective was to explore the determining factors of fear of falling (FOF) in community-dwelling older adults of different ages. A total of 541 community-dwelling older adults aged 65 years and older were investigated and separated into a younger group (n=347) and an older group (n=194). FOF was measured and possible factors affecting FOF were investigated. The prevalence of high FOF in the older group was significantly higher than that in the younger group. Poor sleep quality, low muscle strength, and multimorbidity were independent risk factors for high FOF in the younger group. While poor gait and balance were independent risk factors for high FOF, other factors, such as sex, marital status, education level, drinking status, cognitive ability, and muscle strength were also found to have a significant association with high FOF in the older group. Therefore, differential prevention strategies for high FOF should be considered for community-dwelling older adults of different ages.

OBJECTIVE: To evaluate the effectiveness of high-intensity focused ultrasound (HIFU) combined with hysteroscopy-guided suction curettage (HGSC) in treating cervical pregnancy. MATERIALS AND METHODS: This is a retrospective study. Seven patients with cervical pregnancy who visited the Third Xiangya Hospital of Central South University from January 2015 to December 2020 were enrolled in the current study. All seven patients were treated with HIFU under conscious sedation. All of them underwent HGSC at an average of 2 ± 1 days (range: 1-3 days) after HIFU. Before the therapy, the patient's clinical characteristics were collected, including duration of amenorrhea, gravidity and parity, the patient history of cesarean section and miscarriage, and the size of the gestational sac. The levels of ß-hCG and hemoglobin in serum were also reviewed. To assess the clinical outcomes of this combined treatment, the suction time of HGSC, bleeding volume, the clearance time of ß-hCG, and the time with returning of menstruation were evaluated. RESULTS: All seven patients (average age: 31 ± 6 years) have experienced amenorrhea (duration range, 48 ± 8 days) before the treatment of HIFU. The average number of pregnancies was four, and the number of deliveries was one. Previous medical history showed six patients had cesarean sections, and five patients have been miscarriages. After HIFU treatment, the fetal heartbeats were stopped in all seven patients based on the diagnosis by doppler ultrasound. The bleeding of gestational tissue decreased significantly. All patients had only mild lower abdominal pain, no fever, intestinal damage, or other complications were reported. The average operation time of operative suction curettage was 21 ± 9 min (range: 9-32 min), and the median bleeding volume was 10 ± 8 mL (range: 2-20 mL). Follow-up observations showed that the menstruations were returned in patients at an average of 38 ± 9 days (range: 30-50 days) after the treatment. The ß-hCG decreased from 41773 ± 32242 mIU/mL to 13101 ± 8454 mIU/mL in 29 ± 10 days after surgery. CONCLUSION: Based on these results with small subjects, we concluded that HIFU combined with HGSC might be an effective and safe treatment for patients with cervical pregnancy.

BACKGROUND: Endometriosis is a serious reproductive and general health consequences. Recombinant human IL-37 (rhIL-37) is an inhibitor of inflammation. METHODS: ELISA assay was performed to detect the concentration of cytokines. Flow cytometry was used to analyze cell proportion. Besides, qRT-PCR and western blotting assay were used to detect the level of gene and protein, respectively. Transwell co-culture system was used for the co-culture of dendritic cells (DCs) and CD4+T cells. RESULTS: Our data showed that rhIL-37 inhibited the development of ectopic lesions in the mice with endometriosis, increased Th1/Th2 ratio and induced DCs maturation. The co-culture system of DCs and CD4+T cells demonstrated that rhIL-37 increased Th1/Th2 cell ratio through promoting DCs maturation. Moreover, the expression of IL-4 in the DCs derived from healthy mice was inhibited by rhIL-37 treatment. rhIL-37 increased Th1/Th2 cell ratio through inhibiting IL-4 in DCs. Subsequently, our results proved that rhIL-37 promoted the maturation of DCs via inhibiting phosphorylation of STAT3. Activation of STAT3 could reverse rhIL-37-induced maturation of DCs. CONCLUSION: Overall, rhIL-37 could protect against endometriosis through increasing the ratio of Th1/Th2 cells via inducing DCs maturation and inhibiting IL-4 expression in the DCs. Furthermore, rhIL-37 induced DCs maturation by inhibiting STAT3 phosphorylation. Our data confirmed the protective effect of rhIL-37 in endometriosis. These data may provide a novel idea for the treatment of the disease.

BACKGROUND: Currently, whether daily excess iodized salt intake increases the risk of thyroid nodules and even thyroid cancer remains controversial. Our research group aimed to provide a theoretical basis for the clinical guidance of daily iodized salt intake and the prevention of thyroid nodules through a retrospective analysis of the correlation between daily iodized salt intake and the risk of thyroid nodules and thyroid cancer in Hunan, China. METHODS: This study retrospectively analyzed the data of subjects who underwent a physical examination at the Health Management Center, Third Xiangya Hospital of Central South University, between January 1, 2017, and December 31, 2019. Subjects enrolled in this study underwent thyroid ultrasonography and tests to urine routines and liver and kidney function, and all subjects completed a questionnaire survey. The daily iodized salt intake of the study subjects was estimated based on spot urine methods (Tanaka). A multivariate logistic regression model was used to analyze the relationship between daily iodized salt intake and thyroid nodules and thyroid cancer. RESULTS: Among the 51,637 subjects included in this study, the prevalence of thyroid nodules was 40.25%, and the prevalence of thyroid cancer was 0.76%; among all enrolled subjects, only 3.59% had a daily iodized salt intake less than 5 g. In addition, we found that a daily intake of more than 5 g of iodized salt was not only an independent risk factor for the occurrence of thyroid nodules (odds ratio (OR): 2.08, 95% confidence interval (CI): 1.86-2.31, p < 0.001) but also an independent risk factor for the occurrence of thyroid cancer (OR: 5.81, 95% CI: 1.44-23.42, p = 0.012). A pooled analysis showed a significantly higher risk of thyroid nodules in subjects aged > 60 years with a daily iodized salt intake of more than 5 g compared to subjects aged < 60 years with a daily iodized salt intake of no more than 5 g (OR: 4.88, 95% CI: 4.29-5.54, p < 0.001); the risk of thyroid cancer was not significantly different between subjects aged > 60 years with a daily iodized salt intake of more than 5 g and those aged < 60 years with a daily iodized salt intake of no more than 5 g (OR: 2.15, 95% CI: 0.52-8.95, p = 0.281). The risk of thyroid nodules was not increased in physically active subjects with a daily iodized salt intake of more than 5 g compared to physically inactive subjects with a daily iodized salt intake of no more than 5 g (OR: 1.12, 95% CI: 0.97-1.28, p = 0.111). The same protective effect of physical activity was observed for thyroid cancer in subjects whose daily iodized salt intake exceeded 5 g. The risk of thyroid nodules was reduced for subjects with an education level of postgraduate and above, even when the daily iodized salt intake exceeded 5 g, compared to those with high school education and below and a daily iodized salt intake of no more than 5 g (OR: 0.79, 95% CI: 0.66-0.93, p = 0.005); however, a protective effect of education level on the occurrence of thyroid cancer was not observed. Independent risk factors affecting daily iodized salt intake greater than 5 g included age, triglycerides, family history of tumors, physical activity, and marital status. CONCLUSIONS: Daily intake of more than 5 g of iodized salt increased the risk of thyroid nodules and thyroid cancer, while increased physical activity and education level reduced the risk of thyroid nodules and thyroid cancer caused by iodized salt intake.

PURPOSE: The aim of this study was to retrospectively compare and analyze pregnancy outcomes of patients with uterine fibroids after high intensity focused ultrasound (HIFU) ablation and laparoscopic myomectomy (LM). MATERIALS AND METHODS: The study group consisted of 346 patients with uterine fibroids who wished to conceive, in which 152 patients received HIFU ablation treatment (HIFU group) and 194 patients received LM treatment (LM group). The parents' baseline characters were recorded and the pregnancy outcomes were evaluated in a median follow-up time of 42 months (range: 16 â¼ 81) after the treatment, and the differences of the two groups were compared. RESULTS: Patients with uterine fibroids in HIFU group had a significant shorter pregnancy interval than that in LM group (10 months VS. 13 months, p < .05). No significant differences were observed in pregnancy rate, miscarriage rate, live birth rate, natural pregnancy rate, cesarean section rate, and perinatal complications rate between the HIFU group and the LM group (p > .05). When stratified by age, infertility history, fibroid types, fibroid numbers, and fibroid sizes, there was no statistically significant difference in pregnancy rate between the HIFU group and the LM group (p > .05). CONCLUSIONS: Based on the results from this study, both HIFU and LM can be safely used to treat patients who wish to conceive. The pregnancy outcomes of post-HIFU are similar to that of post-LM.

OBJECTIVE: To investigate the long-term clinical outcomes of patients with adenomyosis treated by high-intensity focused ultrasound (HIFU). MATERIALS AND METHODS: From June 2012 to January 2020, 2311 patients with adenomyosis were treated with HIFU at our center, 1982 patients who have complete clinical data were retrospectively reviewed. Among the patients who completed the follow-up, 485 were treated with HIFU alone, 289 were treated with HIFU followed by GnRH-a, 255 were treated with HIFU combined with Mirena and 594 were treated with HIFU combined with GnRH-a and Mirena. The dysmenorrhea severity pain score and average menorrhagia severity score before and at 3 months, 6 months, 1 year, 2 years, 3 years and 5 years after HIFU were compared. The adverse effects were recorded. In addition, the efficacy between patients treated with GnRH-a and/or Mirena were compared. RESULTS: After HIFU ablation, the dysmenorrhea severity pain score and the menorrhagia severity score were significantly decreased at each follow-up time point. However, it was observed that as the follow-up time increased, the effective rate of HIFU treatment in improving dysmenorrhea and menorrhagia decreased. The 6 months and 3 years follow-up results showed that the efficacy of HIFU combined with Mirena and HIFU combined with GnRH-a and Mirena were significantly higher than HIFU alone and HIFU combined with GnRH-a (p < 0.05). The major complications were rare. CONCLUSION: HIFU is a safe and effective treatment for patients with adenomyosis. HIFU combined with Mirena or HIFU combined with GnRH-a and Mirena can significantly enhance the long-term treatment results.

OBJECTIVES: The current systematic review aims to examine the effect of mind-body exercise on different memory types in the elderly population. METHODS: Four literature databases (Pubmed, Cochrane library, Embase and Sinomed) were searched from inception to March 19, 2019. Randomized controlled trials (RCTs) examining the effect of mind-body exercise on memory in older adults were included. The assessment of risk of bias for the included studies and data synthesis were conducted using the software of review manager 5.3 based on the Cochrane handbook. RESULTS: Twelve eligible RCTs with a total 1051 participants were identified that met the inclusion criteria for the systematic review. Meta-analysis in elderly adults without known neurological diseases showed mind-body exercise intervention had a large effect on general memory (SMD = 1.24, p = 0.005), a moderate effect on short-term memory (SMD = 0.51, p = 0.02) and long-term memory (SMD = 0.78, p < 0.001), a small effect on working memory (SMD = 0.28, p = 0.009), and a moderate effect on episodic memory (SMD = 0.74, p < 0.001) and semantic memory (SMD = 0.59, p = 0.003) compared to no specific exercise intervention. Similar results were also found in elderly adults with known neurological diseases, showing a moderate effect on general memory (SMD = 0.56, p < 0.001), short-term memory (SMD = 0.68, p = 0.01), and long-term memory (SMD = 0.80, p = 0.003); a small effect on working memory (SMD = 0.46, p < 0.001); and a large effect on episodic memory (SMD = 0.91, p < 0.001). CONCLUSION: Compared with no specific exercise, mind-body exercise enhances memory in older adults. However, larger, more robust trials with longer follow-up periods and standardized neuropsychological outcome measures are needed before more definitive conclusions can be drawn.

AIM: Patients with gynaecological cancer often experience high levels of uncertainty in illness during chemotherapy and report unmet supportive care needs. Mobile applications (apps) are increasing being used as an easily accessible alternative to support these patients, but a lack of rigorous trials have been conducted to explore their effectiveness. Based on Mishel's uncertainty in illness theory, the Mobile Gynaecological Cancer Support (MGCS) program is an app-based program that includes four modules: 1) weekly topics, 2) emotional care, 3) discussion centre and 4) health consultation. The aim of this study is to assess the effectiveness of MGCS for Chinese patients with gynaecological cancer receiving chemotherapy in respect of reducing uncertainty in illness and symptom distress and improving quality of life and social support. DESIGN: A multi-centre randomized controlled trial will be used. METHODS: One hundred and sixty-eight patients with gynaecological cancer commencing chemotherapy will be recruited from three university affiliated hospitals and assigned to the control or intervention group with block randomization. The control group will only receive routine care. The intervention group will access the MGCS program for 24 weeks and receive routine care. Health outcomes will be evaluated at baseline, 12 weeks, and 24 weeks. Repeated measures multivariate analysis of covariance (intention-to-treat) will be used to assess the effectiveness of MGCS. DISCUSSION: This is the first trial to explore the effectiveness of an app-based program for patients with gynaecological cancer using a robust and rigorous study design in China. If effective, this trial will provide evidence for an app-based program to support these patients. IMPACT: The knowledge gained can be applied to develop other culturally appropriate app-based programs for cancer groups worldwide, and provide evidence for health policymakers to allocate more resources and train staff for e-health. TRIAL REGISTRATION: ChiCTR2000033678 (Chinese Clinical Trial Registry Registered 08 June, 2020).

INTRODUCTION: Polygoni Multiflori Caulis (PMC) has been used as a traditional Chinese medicine for a long time in China. However, hepatotoxic events of PMC have been reported in recent years, but the potential toxic compounds have remained unclear. Dianthrones as the secondary plant metabolites were revealed to potential hepatotoxicity in a previous study. However, no reports focused on dianthrones in PMC. OBJECTIVE: In the quest for exploring potential hepatotoxic compounds in PMC, the aim of this work was to undertake a comprehensive characterisation of dianthrones in PMC. METHODS: A simple and effective macroporous absorbent resin column chromatography method was established in this study to enrich the minor dianthrones from PMC extracts. Exploration and characterisation of dianthrones in PMC was conducted by an ultra-high-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (UPLC-QTOF-MS/MS) method and information dependent acquisition (IDA) mode. The aglycones of dianthrone glycosides were further verified by acid hydrolysis method. RESULTS: Seventy-two dianthrone glycosides and their five aglycones were discovered and tentatively characterised in PMC for the first time, of which 29 dianthrones were identified as potential new compounds. Dianthrone glycosides could be classified into three types according to their aglycone structures, and their fragmentation pathway rules and diagnosed ions were also summarised comprehensively. CONCLUSION: This was the first comprehensive investigation on dianthrones in PMC. The result would help to fully understand the phytochemical constituents and toxic components in PMC, and highlight the need for further toxicological investigations of the dianthrones in PMC due to their potential hepatotoxicity correlation.

Fetal heart rate plays an essential role in maternal and fetal monitoring and fetal health detection. In this study, a method based on Poincare Plot and LSTM is proposed to realize the high performance classification of abnormal fetal heart rate. Firstly, the original fetal heart rate signal of CTU-UHB database is preprocessed via interpolation, then the sequential fetal heart rate signal is converted into Poincare Plot to obtain nonlinear characteristics of the signals, and then SquenzeNet is used to extract the features of Poincare Plot. Finally, the features extracted by SqueezeNet are classified by LSTM. And the accuracy, the true positive rate and the false positive rate are 98.00%, 100.00%, 92.30% respectively on 2 000 test set data. Compared with the traditional fetal heart rate classification method, all respects are improved. The method proposed in this study has good performance in CTU-UHB fetal monitoring database and has certain practical value in the clinical diagnosis of auxiliary fetal heart rate detection.

OBJECTIVE: With advantages of easy accessibility and various multimedia interactivity formats, online interventions have been developed to improve health outcomes for patients with a variety of gynecological cancers, but evidence regarding their effectiveness for such patients is not well-understood. This review aimed to synthesize study findings that were published in English or Chinese regarding the effectiveness of online interventions on the quality of life, symptom distress, social support, psychological distress, sexual well-being, and body image in patients with gynecological cancer. METHODS: This integrative review adhered to five steps, including problem identification, literature search, quality appraisal, data analysis, and presentation. Ten electronic databases (MEDLINE, ScienceDirect, SpringerLink, PubMed, Wiley Online Journals, Web of Science, OVID, CINAHL Plus with Full Text, China National Knowledge Infrastructure, and Cochrane Library) were searched from the inception of each database to April 2019 in accordance with the rigid and explicit inclusion and exclusion criteria. Version 2018 of the Mixed Methods Appraisal Tool was used for the quality appraisal of the articles. RESULTS: Out of 276 articles, 24 potentially eligible articles were initially identified. A manual search retrieved an additional eligible three articles. After nine articles were excluded, ten quantitative, six qualitative, and two mixed-methods articles were finally included. Online interventions improved quality of life and body images in patients with gynecological cancer, but there were inconclusive effects on symptom distress, social support, psychological distress, and sexual well-being. CONCLUSIONS: Online interventions have been increasingly used as clinically promising interventions to promote health outcomes among patients with gynecological cancer. Studies with more rigorous designs and sufficient sample sizes are needed to elucidate the effectiveness of such online interventions. Healthcare workers can incorporate existing or new online interventions into their routine care to improve health outcomes for patients with gynecological cancer.

Honey-processed Astragalus is a widely used traditional Chinese medicine that has a better effect on reinforcing "Qi" (vital energy) than the raw one. A comparative study of metabolites analysis between them in rat serum for finding the bioactive ingredients was carried out using serum pharmacochemistry and multivariate statistical analysis. The blood collection methods and time were optimized first. Then the prototypes and metabolites in serum samples after oral administration were investigated by ultra-high-performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry integrated with principal component analysis and orthogonal partial least squares discriminant analysis. The contents of metabolites were also analyzed to evaluate the metabolic profile differences. As a result, nine prototypes and 36 metabolites were identified. Only two prototypes and 15 metabolites were different between raw and honey-processed Astragalus. Their biotransformation reactions contained the process of oxidation, demethylation, and hydrolysis in phase I and glucuronide conjugation or sulfate conjugation in phase II. Most of the detected metabolites were transformed from isoflavones and isoflavanes. Our results expand the knowledge about the influence of honey-processing on Astragalus and suggest the different curative effects between raw and honey-processed Astragalus might due to their therapeutic material discrepancy.

Cisplatin (DDP)-based chemotherapy is a standard strategy for ovarian cancer (OC), while chemoresistance remains a major therapeutic challenge. Transcription factor SOX9 has been reported to be associated with tumor cell proliferation, metastasis, and chemoresistance. In the current study, we observed a higher SOX9 expression in OC cell lines; SOX9 overexpression might aggravate the chemoresistance of the OC cell to DDP, whereas its knockdown enhanced the chemoresistance. We screened for candidate microRNAs (miRNAs) which might target SOX9 using online tools and further verified the effect of miR-34c, one of the candidate miRNA that significantly inhibited SOX9 expression, in the regulation of OC cell proliferation and chemoresistance to DDP. Further, we verified the interaction between SOX9 and miR-34c, as well as the involvement of ß-catenin signaling in this process. Through the analysis of the correlation between miR-34c expression and the clinical features of patients with OC, we revealed that miR-34c might inhibit OC cell proliferation and chemoresistance to improve the prognosis of patients with OC. Further, the expression of SOX9, ß-catenin, and c-Myc in OC tissues was upregulated and inversely correlated with miR-34c expression, indicating that rescuing miR-34c expression, thus to inhibit SOX9, ß-catenin, and c-Myc expression presents a promising strategy of reducing the chemoresistance of the OC cell to DDP.

The objective of this study was to prepare time-controlled release etodolac pellets to facilitate drug administration according to the body's biological rhythm, optimize the drug's desired effects, and minimize adverse effects. The preparation consisted of three laminal layers from center to outside: the core, the swelling layer, and the insoluble polymer membrane. Factors influenced the core and the coating films were investigated in this study. The core pellets formulated with etodolac, lactose, and sodium carboxymethyl starch (CMS-Na) were prepared by extrusion-spheronization and then coated by a fluidized bed coater. Croscarmellose sodium (CC-Na) was selected as the swelling agent, and ethyl cellulose (EC) as the controlled release layer. The prepared pellets were characterized by scanning electron microscopy and evaluated by a dissolution test and a pharmacokinetic study. Compared with commercial available capsules, pharmacokinetics studies in beagle dogs indicated that the prepared pellets release the drug within a short period of time, immediately after a predetermined lag time. A good correlation between in vitro dissolution and in vivo absorption of the pellets was exhibited in the analysis.

The objective of this study was to prepare ibuprofen enteric-coated sustained-release pellets (IB-SRPs) and codeine phosphate immediate-release pellets (CP-IRPs) to play a synergistic role in analgesia. The pellets were developed by extrusion-spheronization and fluidized bed coating technology. The single-factor investigation was used to determine the optimal prescription and process. The sustained-release membrane of IB-SRPs was water-insoluble ethyl cellulose (EC), triethyl citrate (TEC) was used as plasticizer, and hydroxypropyl methylcellulose (HPMCP) was chose as porogen. Besides, the immediate-release layer of CP-IRPs was gastric-soluble coating film. The ibuprofen and codeine phosphate compound capsules (IB-CP SRCs) were prepared by IB-SRPs and CP-IRPs packed together in capsules with the optimum doses of 200 and 13 mg, respectively. The prepared pellets were evaluated by scanning electron microscopy and dissolution test. Pharmacokinetic studies in beagle dogs indicated that the optimized IB-CP SRCs had smaller individual differences and better reproducibility comparing with commercial available tablets. Additionally, IB-CP SRCs achieved consistency with in vivo and in vitro tests. Therefore, IB-CP SRCs could play a great role in rapid and long-term analgesic.

OBJECTIVE: This paper investigates the effectiveness of high-intensity focused ultrasound (HIFU) for treating non-neoplastic epithelial disorders of the vulva (NNEDV) and to analyse the factors that affect the effectiveness of HIFU and recurrence. METHODS: This study included a total of 950 patients with pathologically confirmed NNEDV, who underwent HIFU treatment in our hospital between August 2008 and June 2013 and had completed follow-up data. Treatment efficacy and recurrence were evaluated retrospectively by analysing the patients' clinical pathological data and by following up their symptomatic changes. We also explored factors including age, status of menopause, HPV infection, lesion size, pathological type, and symptom severity for their correlation with treatment effectiveness and recurrence. RESULTS: HIFU was effective in alleviating symptoms and improving vulva signs, with a cure rate of 42.2%, an effective rate of 56.1%, and a low recurrence rate of 9.4%. No severe complications were recorded during or after the treatment. The treatment was statistically more effective in younger patients with squamous hyperplasia and smaller lesions than in older patients with lichen sclerosus and larger lesions (P < 0.05). Patients with a longer disease course or with lichen sclerosus had significantly higher recurrence rates than those with a shorter disease course or with squamous hyperplasia (P < 0.05). CONCLUSIONS: HIFU is safe and effective in treating NNEDV. Its effectiveness is correlated with age, size of lesion and pathological type, whereas post-treatment recurrence rates may be related to the duration of the disease and the pathological sub-types.
