[Evaluation of arthroscopic ATFL and CFL repair separately for chronic lateral ankle instability in conjunction with subtalar instability].

Objective: To investigate the clinical efficacy of simultaneous arthroscopic repair of anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) for treating chronic lateral ankle instability (CLAI) in conjunction with subtalar instability (STI). Methods: This study is a retrospective case series study. The clinical data of 15 patients with ankle arthroscopic in the Department of Hand and Foot Surgery, the Second Affiliated Hospital of Soochow University from January 2019 to December 2022 were analyzed retrospectively. There were 11 male cases and 4 female cases, aged (28.6±1.5) years (range: 19 to 39 years). All the patients were evaluated by manual inversion stress X-ray and MRI before operation. Arthroscopically observing and then repairing the ATFL and CFL separately after further diagnostic confirmation. One year after operation, MRI was performed, and visual analogue (VAS) pain scores, American Orthopedic Foot and Ankle Society ankle hindfoot scale (AOFAS-AH) and Karlsson ankle functional scale(KAFS) were evaluated. Data were compared using paired sample t test. Results: The follow-up period was (22.6±2.3) months (range: 12 to 30 months). At last follow-up,the VAS decreased from 6.1±1.4 preoperatively to 1.4±1.2(t=9.482, P<0.01). The AOFAS-AH improved from 50.5±11.7 preoperatively to 94.2±6.1(t=-13.132, P<0.01), and the KAFS improved from preoperatively 44.3±10.8 to 90.8±6.4 (t=-12.510, P<0.01). There were no complications such as recurred instability or joint stiffness. Conclusions: Arthroscopically repairing the ATFL and CFL separately can effectively restore the stability of the ankle and subtalar joint with small trauma. Patients can recover quickly after surgery. It provides a new idea for the clinical treatment of CLAI combined with STI.

[Incidence and mortality of endometrial cancer in China, data from China Cancer Registry Annual Report, 2004-2017].

Objective: To analysis the incidence rate and mortality rate of endometrial cancer in China from 2004 to 2017 according to the data from China Cancer Registry Annual Report. Methods: The incidence and mortality data of endometrial cancer were extracted from the China Cancer Registry Annual Report 2004 to 2017, and the incidence, mortality, number of new cases, number of deaths were extracted according to the region (national, urban, rural and eastern, middle and western areas) and the age composition of population to estimate the incidence and mortality of endometrial cancer nationwide. The age-standardized incidence rate and mortality rate were calculated based on the Chinese standard population in 2000 (ASIRC, ASIRW) and Segi's world population (ASMRC, ASMRW). Join Point regression was used to calculate the annual percentage change of morbidity rate, and Cochran-Armitage trend test was used to analyze the changing trend of morbidity and mortality. Results: From 2004 to 2017, the number of women covered by the China Cancer Registry Annual Report has increased from 35 571 657 to 215 201 995, and the total population of the covered areas has increased from 5.53% to 31.39%. The crude incidence rate of endometrial cancer increased from 6.20/100 000 to 10.06/100 000, and showed an upward trend over time (P<0.001). After adjusting for age, ASIRC increased from 5.75/100 000 in 2004 to 6.79/100 000 in 2017, and ASIRW increased from 5.60/100 000 in 2004 to 6.56/100 000 in 2017, both showing an upward trend over time (all P<0.001). The crude incidence rates in urban area and rural area were respectively 10.89/100 000 and 9.25/100 000 in 2017, and the ASIRC was higher in urban than rural areas (7.14/100 000 vs 6.43/100 000) after adjusting for age. The ASIRW was higher in eastern areas than middle areas and western areas (7.16/100 000 vs 6.44/100 000 vs 5.60/100 000). The incidence rate in rural areas showed more significant growth than urban areas [annual percent change (APC): 3.2% vs 0.7%, P<0.001]. The age-specific incidence rate increased with age and reached a peak in the age group of 50-54 years (25.70/100 000). Incidence rate in the under-40 age group increased more in rural areas than in urban areas (69.84% vs-7.09%). From 2004 to 2017, the age-standardized mortality rate shows a decreasing trend, with the ASMRC from 1.83/100 000 to 1.47/100 000, and the ASMRW from 1.81/100, 000 to 1.46/100, 000. There was no significant difference between urban and rural areas in mortality of endometrial cancer. Age-specific mortality rates increased with age, reaching a peak in the age group 85 years and older (13.16/100 000). Conclusions: Recent years, there was an increasing incidence rate of endometrial cancer in China. Especially in rural areas, the incidence rate of endometrial cancer is increasing rapidly in young women under 40 years of age. There were differences between urban and rural areas and regions in the incidence rate of endometrial cancer. The incidence rates of endometrial cancer in some high-income cities have occupied the first place of female reproductive system malignant cancers. The age-standardized mortality rate of endometrial cancer shows a decreasing trend.

Novel Marker for Predicting Prognosis in Hepatitis B Virus-Associated Decompensated Cirrhosis: Monocyte-To-Albumin Ratio.

BACKGROUND: Early determination of the prognosis in hepatitis B virus-associated decompensated cirrhosis (HBV-DC) patients is important to improve their survival. The present study aimed to determine the predictive ability of monocyte-to-albumin ratio (MAR) for poor prognosis in HBV-DC. METHODS: This work recruited 263 HBV-DC patients admitted to our hospital from November 2020 through March 2022. The clinical data, laboratory parameters, and clinical prognosis of the patients were retrospectively collected and analyzed. RESULTS: Mortality at 30 days was 20.2% (53/263). MAR was found to be higher in the non-survivors compared with the survivors. Higher MAR was associated with higher 30-day mortality, and MAR was identified as an independent predictor of poor prognosis in HBV-DC. Furthermore, the predictive values between MAR and Model for End-Stage Liver Disease score are comparable. CONCLUSIONS: MAR could be potentially used as a novel prognostic marker to predict prognosis in HBV-DC.

Factors of Dental Care Utilization in Foreign-Born Older Chinese Americans.

Good oral health is essential for healthy aging. Regular dental care utilization is instrumental to good oral health. Older immigrants tend to experience poorer oral health and less dental care use as compared with their native-born counterparts in the host country. Older immigrants are particularly vulnerable to interrupted or lost social ties and acculturation challenges after immigration to a new country. This study examined whether and to what extent social relations, acculturation, and perceived oral health needs are associated with dental care utilization in foreign-born older Chinese Americans. Data came from the Population Study of Chinese Elderly in Chicago, which were collected between 2017 and 2019 (N = 3,000). Dental care utilization was dichotomized into "yes" versus "no" in the past 2 y. Social relations were measured by positive and negative relations with spouse, family, and friends. Acculturation was measured by length of stay, behavioral acculturation, and residence in Chinatown. Perceived oral health needs were measured by the presence of problems related to teeth, gums, or bleeding. As guided by the Andersen model, separate logistic regression models were used to investigate factors of dental care utilization. An overall 23.1% reported dental care utilization. Individuals with no negative relations with spouse, family, and friends were 31%, 36%, and 38% less likely to visit a dentist, respectively. Individuals with higher levels of behavioral acculturation were 4% more likely to visit a dentist; individuals living in Chinatown were 45% less likely; and individuals with perceived oral health needs were 2.5 times more likely. Findings illustrate the importance of understanding social relations, immigration-related factors, and perceived oral health needs in dental care utilization in older immigrants.

Atomistic deformation mechanism of silicon under laser-driven shock compression.

Silicon (Si) is one of the most abundant elements on Earth, and it is the most widely used semiconductor. Despite extensive study, some properties of Si, such as its behaviour under dynamic compression, remain elusive. A detailed understanding of Si deformation is crucial for various fields, ranging from planetary science to materials design. Simulations suggest that in Si the shear stress generated during shock compression is released via a high-pressure phase transition, challenging the classical picture of relaxation via defect-mediated plasticity. However, direct evidence supporting either deformation mechanism remains elusive. Here, we use sub-picosecond, highly-monochromatic x-ray diffraction to study (100)-oriented single-crystal Si under laser-driven shock compression. We provide the first unambiguous, time-resolved picture of Si deformation at ultra-high strain rates, demonstrating the predicted shear release via phase transition. Our results resolve the longstanding controversy on silicon deformation and provide direct proof of strain rate-dependent deformation mechanisms in a non-metallic system.

Mechanism of pod shattering in the forage legume Medicago ruthenica.

Pod shattering is a seed dispersal strategy and an important agronomical trait in domesticated crops. The relationship between pod shattering and pod morphology in the genus Medicago is well known; however, the detailed mechanism underlying pod dehiscence in Medicago ruthenica, a perennial legume used for forage production, is unknown. Here, the pod ventral sutures of shatter-resistant and shatter-susceptible M. ruthenica genotypes were examined at 8, 12, 16, and 20 d after flowering. The mechanism of pod shattering was analyzed through microscopic observations, polygalacturonase (PG) and cellulase (CE) activity analyses, and RNA-sequencing (RNA-Seq), and the results were verified via reverse transcriptase-quantitative polymerase chain reaction. Pod shattering at the ventral suture in M. ruthenica occurs via a combination of two mechanisms: degradation of the middle lamella at the abscission layers (ALs) and detachment of lignified cells on either side of the ALs triggered by physical forces. Increased PG and CE activities in the pod ventral suture are essential for AL cell-autolysis in the shatter-susceptible genotype. RNA-Seq revealed that 11 genes encoding PG and CE were highly expressed in the ventral sutures of the shatter-susceptible genotype. The expression levels of auxin biosynthesis-related genes decreased in the AL cells and they were negatively associated with pod dehiscence. These results enhance our understanding of the pod shattering mechanism not only in M. ruthenica but also in other leguminous plants.

Retrospective analysis of risk factors for bone metastasis in newly diagnosed prostate cancer patients.

OBJECTIVE: The aim of the study was to analyze the clinical data of newly diagnosed prostate cancer (PCa) patients with bone metastasis and to explore the relevant risk factors. PATIENTS AND METHODS: The clinical data of 251 patients with PCa, who were initially diagnosed in our hospital from February 2015 to October 2021, were retrospectively analyzed. According to the whole-body bone scan results, patients were divided into the bone metastasis group (n = 66) and the non-bone metastasis group (n = 185). The patient's age, total prostate-specific antigen (TPSA), free PSA (fPSA), prostate volume, alkaline phosphatase (ALP), Gleason score, erythrocyte sedimentation rate (ESR), and pelvic lymph node metastasis were collected. Univariate correlation and multivariate regression analyses, together with receiver operating characteristic curve, were used to analyze PCa bone metastasis-related factors. RESULTS: The incidence of bone metastasis in newly diagnosed PCa was about 26.29% (66/251). Among them, the incidence of pelvic metastasis was the highest, at 78.78% (52/251), and multiple bone metastases were significantly higher than single bone metastasis (80.31% vs. 19.69%). Univariate correlation analysis indicated that age, Gleason score, ESR, TPSA, ALP, fPSA/PSA, capsular infiltration, and pelvic lymph node metastasis (p < 0.05) were highly correlated with PCa bone metastasis. Multivariate Logistic regression analysis showed that TPSA (95% CI: 0.977-1.284, p = 0.007), ALP (95% CI: 1.008-1.080, p = 0.016), Gleasons core (95% CI: 2.110-82.349, p = 0.006), ESR (95% CI: 1.062-1.104, p = 0.003), and pelvic lymph node metastasis (95% CI: 1.537--33.239, p = 0.012) were independent risk factors for bone metastasis of PCa. The cut-off values for TPSA, ALP, Gleason score, and ESR were 33.78 ng/ml, 73.65 U/L, 7.5, and 23.5 mm/h, respectively. Additionally, the respective sensitivities for TPSA, ALP, Gleason score, and ESR were 81.8%, 75.8%, 68.2% and 77.3%, and the respective specificities was 90.3%, 98.9%, 98.4%, and 74.6%. CONCLUSIONS: TPSA, ALP, Gleason score, ESR and pelvic lymph node metastasis are independent risk factors for bone metastasis of PCa.

Dynamic compression of water to conditions in ice giant interiors.

Recent discoveries of water-rich Neptune-like exoplanets require a more detailed understanding of the phase diagram of H2O at pressure-temperature conditions relevant to their planetary interiors. The unusual non-dipolar magnetic fields of ice giant planets, produced by convecting liquid ionic water, are influenced by exotic high-pressure states of H2O-yet the structure of ice in this state is challenging to determine experimentally. Here we present X-ray diffraction evidence of a body-centered cubic (BCC) structured H2O ice at 200 GPa and ~ 5000 K, deemed ice XIX, using the X-ray Free Electron Laser of the Linac Coherent Light Source to probe the structure of the oxygen sub-lattice during dynamic compression. Although several cubic or orthorhombic structures have been predicted to be the stable structure at these conditions, we show this BCC ice phase is stable to multi-Mbar pressures and temperatures near the melt boundary. This suggests variable and increased electrical conductivity to greater depths in ice giant planets that may promote the generation of multipolar magnetic fields.

A validation study of a continuous automatic measurement of the mechanical power in ARDS patients.

The mechanical power (MP) is the energy delivered into the respiratory system over time. It can be computed as a direct measurement of the inspiratory area of the airway pressure and volume loop during the respiratory cycle or calculated by "power equations". The absence of a bedside computation limited its widespread use. Recently, it has been developed an automatic monitoring system inside of a mechanical ventilator. PURPOSE: Our aim was to investigate the repeatability and the accuracy of the measured MP at different PEEP values and tidal volume compared with the calculated MP. MATERIAL AND METHODS: MP was measured and calculated in sedated and paralyzed ARDS patients at low and high tidal volume, at 5-10-15 cmH2O of PEEP both in volume and pressure-controlled ventilation. The same measurements were performed twice. RESULTS: Fifty ARDS patients were enrolled. MP was measured and calculated for a total of 300 measurements. The bias and limits of agreement were 0.38 from -1.31 to 2.0 J/min. The measured and calculated MP were similar in each ventilatory condition. CONCLUSIONS: The mechanical power measured by a new automatic real time system implemented in a mechanical ventilator was repeatable and accurate compared with the computed one.

[Applied anatomical study and clinical application of the caudate lobe boundary and ductal system of the liver].

Objective: To explore the relationship between the hepatic caudate lobe boundary and the ductal system so as to guide the identification of the anatomical relationship during liver surgery. Methods: The specific parts were observed and the liver parenchyma was removed according to 41 cadaveric liver autopsy specimens. The critical relationship between the hepatic caudate lobe and other ducts was observed to explore the reticular duct structure. Results: The plane formed by the hepatic hilar plate and Arantius ligament served as the boundary between the caudate lobe and other hepatic lobes. The caudate lobe hepatic portal vein was composed of numerous small branches from its left and right branches. The portal vein adjacent to the vena cava was mainly derived from the left branch, and to a lesser extent from the right branch. Blood was drained straight from the caudate lobe vein into the inferior vena cava via the short hepatic vein. There were three or four bile duct branches in the caudate lobe. The main source of arterial blood flow were the left and right branches of the hepatic artery. An avascular zone of loose connective tissue was found between the caudate lobe and the retrohepatic inferior vena cava. Conclusion: The hepatic caudate lobe is an independent lobe. During hepatic caudate lobe surgery, the plane formed by the hepatic hilar plate and Arantius ligament can serve as the boundary between the caudate lobe and other hepatic lobes and be used for anatomical site identification. The duct system of the caudate lobe's is complicated, but it also has its own distinct regularity.

[Investigation on prevalence of Schistosoma japonicum infections in wild mice in Shitai County, Anhui Province, 2018].

OBJECTIVE: To investigate the prevalence of Schistosoma japonicum infection in wild mice in Shitai County, Anhui Province, so as to provide insights into precise control of the source of S. japonicum infections. METHODS: Wild mice were captured using the trapping method for three successive nights at snail-infested settings from Jitan Village of Jitan Township, and Shiquan Village and Xibai Village of Dingxiang Township, Shitai County, Anhui Province in June and October, 2018. All trapped wild mice were sacrificed and liver and mesenteric vein specimens were collected for detection of S. japonicum eggs using microscopy, while the fecal samples in mouse intestines were collected for identification of S. japonicum infections using Kato-Katz technique. In addition, the population density of trapped wild mice was estimated and the prevalence of S. japonicum infection was calculated in trapped wild mice. RESULTS: A total of 376 wild mice were trapped from three villages in Shitai County. The population density of trapped wild mice was 9.1% (376/4 124), and the prevalence of S. japonicum infection was 24.2% (91/376) in trapped wild mice. The highest prevalence of S. japonicum infection was detected in Shiquan Village of Dingxiang Township (30.1%), and the lowest prevalence was seen in Xibai Village of Dingxiang Township; however, there was no significant difference in the prevalence of S. japonicum infection in trapped wild mice among three villages (χ2= 4.111, P > 0.05). In addition, there was no significant difference in the prevalence of S. japonicum infection in wild mice captured between on June (26.8%, 34/127) and October (22.9%, 57/249) (χ2 = 0.690, P = 0.406). The trapped wild mice included 6 species, including Rattus norvegicus, Niviventer niviventer, R. losea, Apodemus agrarius, Mus musculus and N. coning, and the two highest prevalence of S. japonicum infection was detected in R. losea (34.9%, 22/63) and R. norvegicus (31.2%, 44/141). CONCLUSIONS: The prevalence of S. japonicum infections is high in wild mice in Shitai County, and there is a natural focus of schistosomiasis transmission in Shitai County.

Development of Faraday rotation measurements on Keda Reconnection eXperiment (KRX) device.

The Faraday-effect based polarimeter and interferometer are developed for non-perturbation magnetic field and density measurements on the Keda Reconnection eXperiment (KRX) device. The magnetic reconnection is externally driven by a pair of parallel current plates. To design this instrument and provide an alternative way to facilitate theory-experiment comparisons via forward modeling of the diagnostics process with full plasma dynamics given by simulation, we develop a synthetic diagnostics based on 2D photonic integrated circuit simulation for magnetic reconnection on the KRX. The view-line geometry is optimized and wavelengths (1 mm) of the polarimeter and interferometer are selected to ensure the sensitivity of measurement on the KRX. We have simulated magnetic reconnection on the x-line (x-z plane) with horizontal viewing and vertical viewing for line of sight measurements. It is found that the current sheet width and indicator of magnetic reconnection can be inferred directly from the dynamics of Faraday rotation even with the line-integrated character of polarimeter-interferometer diagnostics.

The cross-polarization scattering system for the magnetic fluctuation measurement in the Experimental Advanced Superconducting Tokamak.

The cross-polarization scattering (CPS) system for magnetic fluctuation measurements in the Experimental Advanced Superconducting Tokamak (EAST) has been designed and installed. Different from the Doppler reflectometer (DR) system, the CPS system detects the perpendicular polarization of the electromagnetic wave induced by magnetic fluctuations B̃. The CPS system in the EAST has been developed from the existing Doppler reflectometer system, and they are integrated together for simultaneous measurement of magnetic and density fluctuations. Ray-tracing simulations are used to calculate the scattering locations and the wavenumber coverage of the magnetic fluctuation for CPS. In the experiments, the CPS and DR system data were different in Doppler shift, amplitude, and spectrum broadening. In this article, the hardware design, the ray tracing, and the preliminary results of the system in the EAST are presented.

[Asbestos-induced malignant peritoneal mesothelioma complicated with lung cancer:a case report].

Asbestos is harmful to human, and populations with occupational and environmental exposure to respirable asbestos fibers have higher risk of cancers like malignant mesothelioma and lung cancer. At present, patient with asbestos-induced malignant peritoneal mesothelioma and lung cancer is rare. In this study, we analyzed the clinical data of a case of asbestos-induced malignant peritoneal mesothelioma complicated with lung cancer to investigate the diagnosis and treatment of this disease.

Immigration and Oral Health in Older Adults: An Integrative Approach.

The aim of this study was to develop an integrative framework on aging, immigration, and oral health. The methodology was a critical review that used immigration as a social determinant framework through which to evaluate its impact on the oral health of older immigrants. We reviewed recent empirical evidence on factors related to oral health in older immigrants. In a systematic search across multiple databases, we identified 12 eligible studies in this review. Among the eligible studies, most were conducted among East Asian immigrants (8 articles), followed by non-Hispanic White/European origin (2 articles), Mexican origins (1 article), and Iran and other Middle East regions (1 article). The research revealed knowledge gaps in the evidence base, including the dynamic relationship between acculturation and oral health, the role of environmental factors on oral health for immigrants, psychosocial stressors and their relationship with oral health, and oral health literacy, norms, and attitude to dental care utilization and oral hygiene practices. The development of the integrative framework suggests the pathways/mechanisms through which immigration exerts influences on oral health in later life. This provides opportunities for researchers, practitioners, and policy makers to gain greater insights into the complex associations between immigration and oral health among older adults.

Environmental Exposure-Associated Human Health Risk of Dioxin Compounds in the Vicinity of a Municipal Solid Waste Incinerator in Shanghai, China.

In order to assess environmental exposure-associated human health risk of dioxin compounds for the population in the vicinity of a municipal solid waste incinerator (MSWI) in Shanghai, the atmospheric samples (n = 24) and soils samples (n = 96) were collected and analyzed to obtain the concentration level, pollution characteristics and seasonal changes of dioxin compounds in environmental medias. The toxicity equivalent concentration range of 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) was 30.9-409 fg WHO-TEQ·m-3 in atmosphere and 0.362-8.55 ng WHO-TEQ·kg-1 in soil. The non-carcinogenic health risk and carcinogenic health risk from PCDD/Fs environmental exposure of people living in the vicinity of the MSWI in Shanghai were all within the allowable range of the US Environmental Protection Agency, which implied that the MSWI in Shanghai did not produce additional risk for the population living in its vicinity.

Therapeutic effects of chimeric antigen receptor T cells (CAR-T) on relapse/refractory diffuse large B-cell lymphoma (R/R DLBCL): a meta-analysis.

OBJECTIVE: Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma (NHL). This study aimed to systematically evaluate the efficacy of chimeric antigen receptor T cells (CAR-T) in treating relapse/refractory DLBCL (R/R DLBCL) and associated complete-remission rate (CR). MATERIALS AND METHODS: PubMed, Cochrane Library, CNKI, VIP, CBM, and Wanfang databases were searched, and literature was collected up to January 2019. According to inclusion criteria and exclusion criteria, two researchers independently reviewed and screened literature, extracted required data and crossly checked them. This meta-analysis was conducted using RevMan 5.3 software. RESULTS: This study finally included 13 English literatures and 263 cases. There was no heterogeneity among all these studies, therefore, fixed effect model was used. Meta-analysis findings showed that total CR rate of R/R DLBCL treated with CAR-T was 46.8% (95% CI: 0.408-0.533). Subgroup analysis showed that CR rate of CD28 group was slightly higher [52.5%, with 95% confidence interval (CI): 0.441-0.602] compared to that of 4-1BB group (41.5%, with 95% CI: 0.324-0.510). CR rate of CD19 group was slightly higher (49.2%, with 95% CI: 0.429-0.556) compared to that of CD20 group (42.2%, with 95% CI: 0.231-0.639). Funnel chart of total CR rate, co-stimulatory factor, and target antigen demonstrated fundamental symmetry. Moreover, age, HSCT administration, CAR-T cell counts, and drug pre-treatment also affected immunotherapy on CAR-T on R/R DLBCL. CONCLUSIONS: CAR-T treatment for R/R DLBCL demonstrated evident curative effect and high complete remission rate. CAR-T cell immunotherapy would be expected to become mainstream therapy for hematolymph system tumors.

[Endemic situation of schistosomiasis in national surveillance sites of Hunan Province from 2015 to 2019].

OBJECTIVE: To analyze the changes in the endemic situation of schistosomiasis in national surveillance sites of Hunan Province, so as to provide scientific basis for the development of the schistosomiasis elimination programme in the province. METHODS: According to the requirements of the National Guidelines for Schistosomiasis Surveillance in China (2014 version), a total of 41 national schistosomiasis surveillance sites were assigned in all disease-endemic counties (districts) across Hunan Province. During the period between 2015 and 2019, Schistosoma japonicum infections were monitored in local residents, mobile populations and livestock, and snail status was monitored. The morbidity due to schistosomiasis and snail status was compared between years. RESULTS: The sero-prevalence of S. japonicum infections was 2.57% and 1.56% in local residents and mobile populations in national surveillance sites of Hunan Province from 2015 to 2019, respectively, and the sero-prevalence appeared a tendency towards a decline over years. A higher sero-prevalence rate of S. japonicum infections was seen in men than in women (P < 0.01). During the 5-year study period, the sero-prevalence rate of human S. japonicum infections appeared a tendency towards a decline in the marshland, embankment, inner embankment and hilly types of endemic areas over years. There were 44 and 19 egg -positives detected in local residents and 5 and 1 egg-positives in mobile populations in 2015 and 2016 respectively. A total of 9 346 domestic animals were monitored from 2015 to 2019, and 6 egg-positives were detected in 2015 and 2016 (all were bovine). A total of 0.155 billion m2 settings were surveyed from 2015 to 2019, and the mean density of living snails appeared a tendency towards a decline over years, with a 45.79% reduction in 2019 as compared to 2015. However, no S. japonicum infections were identified in snails during the 5-year period. A total of 1 469 mixed snail samples were detected using loop-mediated isothermal amplification (LAMP), and 6 positive snail samples were identified in 2015 (one sample) and 2017 (5 samples). CONCLUSIONS: The overall endemic situation of schistosomiasis appears a tendency towards a decline in Hunan Province, and the prevalence of S. japonicum infections is at a low level in humans and livestock; however, there is still a risk of schistosomiasis transmission. Improvements of health education, intensification of schistosomiasis examinations in mobile populations and reinforcement of the surveillance-response system is required to consolidate the achievements of schistosomiasis control in Hunan Province.

Acupuncture for recurrent urinary tract infection in women: a systematic review and meta-analysis.

BACKGROUND: Increasing antibiotic resistance has motivated interest in non-antibiotic prophylaxis of recurrent urinary tract infections (rUTI). OBJECTIVES: To conduct a systematic review of the current state of evidence of acupuncture for uncomplicated rUTI in women. SEARCH STRATEGY: Nine databases (PubMed, Embase, CENTRAL, CINAHL, AMED, CBM, CNKI, CQVIP, Wanfang) were searched from inception to February 2019. SELECTION CRITERIA: Randomised controlled trials (RCTs) evaluating the effects of acupuncture and related therapies for prophylaxis or treatment of uncomplicated rUTI in women were included. DATA COLLECTION AND ANALYSIS: Risk of bias was assessed, and the quality and strength of evidence evaluated using the GRADE framework. Results were reported as risk ratios (RR) for dichotomous outcomes or mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI). MAIN RESULTS: Five RCTs involving 341 participants were included. Methodological quality of studies and strength of the evidence were low to moderate. The chance of achieving a composite cure with acupuncture therapies was greater than that with antibiotics (three studies, 170 participants, RR 1.92, 95% CI 1.31-2.81, I2  = 38%). The risk of UTI recurrence was lower with acupuncture than with no treatment (two studies, 135 participants, RR 0.39, 95% CI 0.26-0.58, I2  = 0%) and sham acupuncture (one study, 53 participants, RR 0.45, 95% CI 0.22-0.92). CONCLUSIONS: Acupuncture appeared to be beneficial for treatment and prophylaxis of rUTIs, noting the limitations of the current evidence. Given the growing challenge of antibiotic resistance, there is a need for high-quality RCTs of non-pharmacological interventions such as acupuncture. TWEETABLE ABSTRACT: This review found that acupuncture may improve treatment and prevent recurrence of urinary tract infection in women.
