Does air pollution inhibit digital finance? Evidence from Chinese prefecture-level cities.

Air pollution poses significant health and economic challenges globally and specifically affecting China. Although air pollution has been associated with decreased productivity and biases in decision-making, its effect on the development of digital finance has received limited attention in the literature. By employing city-level data from China covering the period from 2013 to 2020, this research examines the impact of air pollution on digital finance. The results show that deteriorating air quality has a negligible impact on digitalization, whereas it has a negative impact on financial inclusion, measured by usage and coverage metrics. The negative impact on financial inclusion is more noticeable in economically weaker and less developed urban areas and low R&D than in developed areas and economically robust cities. The mechanism analysis shows that air pollution reduces human capital quality, resulting in a decline in financial inclusivity. These findings have significant policy implications, underscoring the necessity for approaches that simultaneously tackle air pollution and foster financial innovation.

HHV-6B- and HHV-7-associated choroiditis secondary to acute myelogenous leukemia: a case report.

We report a case of human herpes virus 6 (HHV-6)- and human herpes virus 7 (HHV-7)-associated choroiditis in an immunocompromised woman. A 42-year-old Chinese woman with a history of acute myelogenous leukemia presented with blurred vision and black floaters in her right eye. Anterior segment examination findings were normal. Ophthalmoscopic examination revealed a subretinal lesion in the superonasal peripapillary region with several punctate hemorrhages. Optical coherence tomography showed a crater-like choroidal protuberance, associated with retinal pigment epithelium rupture and full-thickness retinal edema in the involved area. Indocyanine green angiography demonstrated a broad hypofluorescent lesion in the choroid. The patient was diagnosed with choroiditis. Subsequently, metagenomic next-generation sequencing revealed HHV-6B and HHV-7 DNA in the aqueous humor. Therefore, antiviral therapy was initiated. The patient experienced resolution of all symptoms and signs after treatment with intravenous foscarnet and oral acyclovir. The findings in this case indicate that HHV-6 and HHV-7 can cause ocular infection, particularly in immunocompromised patients.

Machine learning identifies prominent factors associated with cardiovascular disease: findings from two million adults in the Kashgar Prospective Cohort Study (KPCS).

BACKGROUND: Identifying factors associated with cardiovascular disease (CVD) is critical for its prevention, but this topic is scarcely investigated in Kashgar prefecture, Xinjiang, northwestern China. We thus explored the CVD epidemiology and identified prominent factors associated with CVD in this region. METHODS: A total of 1,887,710 adults at baseline (in 2017) of the Kashgar Prospective Cohort Study were included in the analysis. Sixteen candidate factors, including seven demographic factors, 4 lifestyle factors, and 5 clinical factors, were collected from a questionnaire and health examination records. CVD was defined according to International Clinical Diagnosis (ICD-10) codes. We first used logistic regression models to investigate the association between each of the candidate factors and CVD. Then, we employed 3 machine learning methods-Random Forest, Random Ferns, and Extreme Gradient Boosting-to rank and identify prominent factors associated with CVD. Stratification analyses by sex, ethnicity, education level, economic status, and residential setting were also performed to test the consistency of the ranking. RESULTS: The prevalence of CVD in Kashgar prefecture was 8.1%. All the 16 candidate factors were confirmed to be significantly associated with CVD (odds ratios ranged from 1.03 to 2.99, all p values < 0.05) in logistic regression models. Further machine learning-based analysis suggested that age, occupation, hypertension, exercise frequency, and dietary pattern were the five most prominent factors associated with CVD. The ranking of relative importance for prominent factors in stratification analyses showed that the factor importance generally followed the same pattern as that in the overall sample. CONCLUSIONS: CVD is a major public health concern in Kashgar prefecture. Age, occupation, hypertension, exercise frequency, and dietary pattern might be the prominent factors associated with CVD in this region.In the future, these factors should be given priority in preventing CVD in future.

The association between acromial anatomy and articular-sided partial thickness of rotator cuff tears.

BACKGROUND: Acromial anatomy has been found to be correlated with degenerative full-thickness rotator cuff tears in current studies. However, research on the relationship between acromial anatomy and articular-sided partial thickness of rotator cuff tears (PTRCTs) is still lacking. The purpose of this study was to evaluate whether these imaging graphic parameters exhibit any association between acromial anatomy and degenerative articular-sided PTRCTs. METHODS: Between January 2016 and December 2018, a total of 91 patients without a history of trauma underwent arthroscopy as an articular-sided PTRCT group. In the control group, with age- and sex-matched patients, we selected 91 consecutive outpatient patients who underwent shoulder magnetic resonance imaging (MRI) because of shoulder pain and an MRI diagnosis of only synovial hyperplasia and effusion. MRI was used to measure the acromial type, acromiohumeral distance (AHD), lateral acromial angle (LAA), acromion index (AI), and critical shoulder angle (CSA) by 2 independent observers. RESULTS: The acromion type, AHD and LAA showed no difference between degenerative articular-sided PTRCTs and controls (P = 0.532, 0.277, and 0.108, respectively). AI and CSA were significantly higher in degenerative articular-sided PTRCTs (P = 0.002 and 0.003, respectively). A good correlation was found between AI and CSA to measurement(Pearson correlation coefficient = 0.631). CONCLUSIONS: Our study revealed that higher AI and CSA were found in degenerative articular-sided PTRCTs. Acromial anatomy with a large acromial extension was associated with the occurrence of degenerative articular-sided PTRCTs.

New advances in the discovery of anti-enterovirus-71 agents / 药学学报

In recent years, enterovirus infection has become a frequent epidemic and developed into an important public health problem. For example, hand-foot-mouth disease has become a common infection among children in China. Hand-foot-mouth disease (HFMD) has been spreading globally since 1997, especially in the Asia-Pacific region. Enterovirus 71 (EV71) is one of the main pathogens causing HFMD. And now there is no drug available to treat EV71 infection. This review summarizes the research progress of anti-enterovirus-71 drugs from the perspective of medicinal chemistry.

The role of arthroscopic release of gluteal muscle contracture in improving patellofemoral instability.

BACKGROUND: Gluteal muscle contracture (GMC) is a notable problem in some developing countries and includes features such as a snapping sound of the hip, abnormal gait, and unusual posture when patients squat with the knees together. Arthroscopic release can not only resolve symptoms, as previously reported, but can also greatly improve accompanying patellofemoral instability. This study was conducted to evaluate the effect of arthroscopic release of GMC on patellofemoral instability and its underlying mechanism. METHODS: A total of nearly 500 patients who underwent arthroscopic release of GMC over 2.5 years were filtered, and 54 patients were enrolled in the study. The selected research subjects all had combined patellofemoral instability preoperatively. The Lysholm scores and CT scans of the knee were evaluated pre- and postoperatively. RESULTS: The mean follow-up time was 12.2 months. All of the surveyed patients had satisfactory clinical outcomes for hip snapping sounds and abnormal gait. In addition, a significant difference (p < 0.05) was observed between pre- and postoperative Lysholm scores, along with significant knee pain relief. Furthermore, the changes in CT scan parameters were significant as well. The average patellar tilt angle (PTA), patellofemoral index (PFI), and lateral patellar displacement (LPD) were obviously decreased (p < 0.05) after the release. Conversely, the mean lateral patellofemoral angle (LPFA) showed a clear difference (p < 0.05) between preoperative and postoperative CT examinations. CONCLUSIONS: Arthroscopic release of GMC can reduce the tilt and lateral shift of the patella and enhance its stability due to the release of the iliotibial band.

Arthroscopic knotless single-row repair preserving full footprint versus tear completion repair for partial articular-sided rotator cuff tear.

BACKGROUND: The comparison of clinical outcomes of arthroscopic footprint-preserving knotless single-row repair with the tear completion repair technique for articular-sided partial-thickness rotator cuff tears (PTRCTs) remains unclear. METHODS: A total of 68 patients diagnosed with articular-sided PTRCTs who underwent rotator cuff repair between December 2014 and June 2015 were included. Of the 68 patients, 30 received footprint-preserving knotless single-row repair (group 1) and 38 received the tear completion repair technique (group 2). Preoperative and postoperative assessments were compared. RESULTS: Both groups had significantly improved American Shoulder and Elbow Surgeons (ASES) scores (group 1: 48.2 preoperatively to 81.9 postoperatively, p < 0.001; group 2: 47.1 preoperatively to 84.9 postoperatively, p < 0.001) and visual analog scale (VAS) pain score (group 1: 6.0 preoperatively to 0.93 postoperatively, p < 0.001; group 2: 6.1 preoperatively to 1.1 postoperatively, p < 0.001), showing that the two procedures significantly improved postoperative shoulder function. No significant differences were shown in ASES score or VAS pain score between the two groups ( p > 0.05). The mean operation time was significantly shorter in group 1 with an average of 48.1 min than in group 2 with an average of 60.4 min ( p < 0.001). CONCLUSIONS: Footprint-preserving knotless single-row repair obtains similar clinical results compared to tear completion repair in the treatment of articular-sided PTRCTs. Footprint-preserving knotless single-row repair may be a convenient choice for the treatment of articular-sided PTRCTs. Randomized controlled studies are needed to investigate whether the footprint-preserving knotless single-row repair yields better long-term outcomes through the protection of the bursal cuff and restoration of the healthy footprint.
