BACKGROUND: Early control of low-density lipoprotein cholesterol (LDL-C) is crucial for reducing the progress of cardiovascular disease. However, its additional role to the risk of primary osteoporosis in men with coronary heart disease was inconclusive. Our study aims to determine the association of LDL-C and its trajectories for osteoporosis risk in the middle-aged and aged men of China. METHODS: The retrospective cohort study of 1546 men aged 69.74 ± 11.30 years conducted in Beijing, China from 2015 to 2022. And the incidence of primary osteoporosis was annually recorded. LDL-C trajectories were further identified by latent class growth model using repeated measurements of LDL-C. The association of baseline LDL-C for osteoporosis was estimated using hazard ratio (HR) with 95% CI in Cox proportional hazard model, while mean level and trajectories of LDL-C for osteoporosis were evaluated using odds ratio (OR) with 95% CI in logistic regression model. RESULTS: During the median 6.2-year follow-up period, 70 men developed primary osteoporosis. The higher level of baseline LDL-C (HR = 1.539, 95% CI: 1.012-2.342) and mean LDL-C (OR = 2.190, 95% CI: 1.443-3.324) were associated with higher risk of osteoporosis in men with coronary heart disease after adjusted for covariates. Compared with those in the LDL-C trajectory of low-stable decrease, participants with medium-fluctuant trajectory, whose longitudinal LDL-C started with a medium LDL-C level and appeared an increase and then decrease, were negatively associated with osteoporosis risk (OR = 2.451, 95% CI: 1.152-5.216). And participants with initially high LDL-C level and then a rapid decrease demonstrated a tendency towards reduced risk (OR = 0.718, 95% CI: 0.212-2.437). CONCLUSIONS Elevated LDL-C level and its long-term fluctuation may increase the risk of primary osteoporosis in men. Early controlling a stable level of LDL-C is also essential for bone health.

OBJECTIVE: To explore the clinical therapeutic effect of light and heat of moxibustion for knee osteoarthritis (KOA). METHODS: A total of 216 patients with KOA were randomized into a traditional moxibustion group (72 cases, 8 cases dropped off), a moxibustion light group (72 cases, 9 cases dropped off) and a moxibustion heat group (72 cases, 10 cases dropped off).The special light-heat separation moxibustion cup was applied, the patients in the traditional moxibustion group received the treatment of moxibustion, the patients in the moxibustion light group received the treatment of moxibustion light and the patients in the moxibustion heat group received the treatment of moxibustion heat. The acupoint selection of the three groups was Neixiyan (EX-LE 4), Dubi (ST 35) and Zusanli (ST 36), the treatment was given 20 min each time, 3 times a week, 4 weeks were required totally, and the follow-up surveys were made 4 and 8 weeks after treatment. The scores of Western Ontario and McMaster University osteoarthritis index (WOMAC) and visual analogue scale (VAS) were observed before treatment, after 2 and 4 weeks of treatment, 4 and 8 weeks after treatment. The therapeutic effects were evaluated according to the criterion of patient global assessment (PGA) after 4 weeks of treatment and 8 weeks after treatment. RESULTS: Compared with before treatment, the pain scores, stiffness scores, physical function scores and total scores of WOMAC were reduced after 2, 4 weeks of treatment and 4 weeks after treatment in the three groups (<0.05). The pain scores, stiffness scores, physical function scores and total scores of WOMAC were reduced 8 weeks after treatment in the traditional moxibustion group and the moxibustion heat group (<0.05). The stiffness score, physical function score and total score of WOMAC were reduced 8 weeks after treatment in the moxibustion light group (<0.05). The pain score, physical function score and total score of WOMAC in the traditional moxibustion group after 4 weeks of treatment were lower than the moxibustion light group (<0.05). Compared with before treatment, the VAS scores were reduced after 2, 4 weeks of treatment and 4 , 8 weeks after treatment in the three groups (<0.05). The improvement rates in the traditional moxibustion group and the moxibustion heat group after 4 weeks of treatment and 8 weeks after treatment were superior to the moxibustion light group (<0.05). CONCLUSION The light and heat of moxibustion have therapeutic effect for KOA, and the therapeutic effect of moxibustion heat is superior to moxibustion light.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.

Objective To analyze the correlation between inspiratory muscle strength and pulmonary ventilation function in chronic obstructive pulmonary disease (COPD) patients.Methods A total of 41 COPD patients admitted in the Second Xiangya Hospital from January to September 2018 were screened.The inspiratory muscle strength (MIP) and peak inspiratory flow (PIF) of patients were measured by using POWER breathe K-5 tester.The MIP was also calculated as a percentage of the predicted value.A pulmonary function detector was used to measure the forced vital capacity (FVC),forced expiratory volume in 1 second (FEV1 ％),FEV1 as a percentage of FVC (FEV1/FVC％),peak expiratory flow (PEF),forced expiratory flow as a percentage of the predicted value (FEF 50％) at 50％ of vital capacity and forced expiratory flow rate as a percentage of the predicted value (FEF 75％) at 75％ of vital capacity.According to the Gobal Inistiative for chronic Obstructive Lung Disease (GOLD) classification method of COPD patients,the corresponding MIP value and PIF value of the patients were divided into 4 groups and conducted the comparison between groups.Pearson correlation was used to analyze the correlation between the above-mentioned inspiratory muscle strength test values and lung ventilation function test values,and a scatter diagram was drawn for the ones that had a correlation.Results Among the 41 patients,39 (95.1％) had a decrease in inspiratory muscle strength.According to the GOLD classification,the mean MIP value has a difference among the 4 groups.The mean MIP of grade Ⅲ was [(47.09 ± 29.42) cmH2O],which was higher than that of grade Ⅳ of [(24.72 ± 7.66) cmH2 O] (P ＜ 0.05).There was no difference between PIF.The MIP was positively correlated with FVC (P ＜0.05).There was no correlation between MIP and FEV1 ％,FEV1/FVC％,PEF,FEF50％ and FEF75％ (P ＞0.05).The MIP as a percentage of the predicted value had a weak positive correlation with FVC and FEV1％ (P ＜0.05).There was no significant correlation between MIP as a percentage of the predicted value and FEV1/FVC％,PEF,FEF50％ and FEF75％ (P ＞0.05).PIF had a weak positive correlation with FVC,PEF,FEF50％ and FEF75％,with statistically significant difference (P ＜ 0.05).There was no significant correlation between PIF and FEV1 ％ and FEV1/FVC％ (P ＞0.05).Conclusions Inspiratory muscle dysfunction was common in patients with COPD.There was a difference in MIP among different GOLD lung function classification in COPD patients.Some values of the inspiratory muscle strength and lung ventilation function had a weak-moderate correlation,while some values had no correlation.Therefore,inspiratory muscle strength test cannot replace the lung ventilation function test in COPD patients.

OBJECTIVETo investigate the effect of combined application of Xuebijing Injection ( , XBJ) and resolvin D1 (RvD1) on survival rate and the underlying mechanisms in mice with sepsisinduced lung injury.

METHODSThe cecal ligation and puncture (CLP) method was used to develop a mouse sepsis model. Specific pathogen free male C57BL/6 mice were randomly divided into 5 groups (n=20 each): sham, CLP, CLP+XBJ, CLP+RvD1 and CLP+XBJ+RvD1. After surgery, mice in the CLP+XBJ, CLP+RvD1 and CLP+XBJ+RvD1 groups were given XBJ (25 μL/g body weight), RvD1 (10 ng/g body weight), and their combination (the same dose of XBJ and RvD1), respectively. In each group, 12 mice were used to observe 1-week survival rate, while the rest were executed at 12 h. Whole blood was collected for flow cytometric analysis of leukocyte adhesion molecules CD18, lung tissues were harvested for observing pathological changes, and testing the activity of myeloperoxidase (MPO) and the expression of intercellular cell adhesion molecule 1 (ICAM-1).

RESULTSCompared with the CLP group, the histopathological damage of the lung tissues was mitigated, MPO activity was decreased in the CLP+XBJ and CLP+RvD1 groups (P<0.05). In addition, the 1-week survival rate was improved, proportion of CD18-expressing cells in whole blood and ICAM-1 protein expression in lung tissue were decreased in the CLP+XBJ+RvD1 group (P<0.05 or P<0.01).

CONCLUSIONSXBJ together with RvD1 could effectively inhibit leukocyte adhesion, reduce lung injury, and improve the survival rate of mice with sepsis.

In order to develop a rapid detection kit for novel avian influenza virus (AIV) subtype H7N9, two sets of specific primers and probes were designed based on the nucleotide sequences of hemagglutinin antigen (HA) and neuraminidase antigen (NA) of novel H7N9 virus (2013) available in GenBank to establish the method of TaqMan probe-based multiplex real-time RT-PCR for rapid detection of AIV subtype H7N9. The primer and probe of HA were for all H7 subtype AIVs, while the primer and probe of NA were only for novel N9 subtype AIVs. The results showed that this method had high sensitivity and specificity. This method was applicable to the testing of positive standard sample with a minimum concentration of 10 copies/microL; it not only distinguished H7 subtype from H1, H3, H5, H6, and H9 subtypes, but also distinguished novel N9 subtype from traditional N9 subtype. A total of 2700 samples from Zhuhai, China were tested by this method, and the results were as expected. For the advantages of sensitivity and specificity, the method holds promise for wide application.

BACKGROUNDAberrantly expressed microRNAs are a hallmark of cancer, and microRNA expression profiling is associated with tumor progression and response to chemotherapy, suggesting their potential application as prognostic and predictive biomarkers. The role of microRNAs in lung cancer remains elusive. It has been recently reported that epidermal growth factor receptor (EGFR) and hepatocyte growth factor receptor (MET) tyrosine kinase can regulate expression of specific microRNAs including miR-30b, miR-30c, miR-221, miR-222, miR-103 and miR-203, and induce tumorigenesis and gefitinib resistance in lung cancers. We intend to study the role of miR-30b and miR-30c expression in predicting response to tyrosine kinase inhibitors (TKIs) in non-small cell lung cancer (NSCLC).

METHODSWe have therefore retrospectively examined expression of miR-30b miR-30c in 41 formalin fixed paraffin embedded tissue samples from NSCLC patients when TKIs were used as first line therapy.

RESULTSWe found a significant correlation between expression of miR-30b and miR-30c. Furthermore, miR-30b and miR-30c expression correlated with short-term response. Kaplan-Meier analysis further revealed that the expression of miR-30b and miR-30c predicted progression free survival and the overall survival rate in the examined cohort.

CONCLUSIONOur study identified miR-30b and miR-30c as useful prognostic predictors in NSCLC patients who underwent first line treatment with TKIs.

There were no cases with abdominal pain,diarrhoea and withdraw recurrence in the treatment group,and compared with those of the control group, the differences were statistically significant (x2 =19.498,7.275,37.394,respectively;P ＜0.05 ).Conclusions Yoga exercise is an effective method for the constipation resulted from atypical antipsychotics with no adverse reaction.

Objective To investigate the status of infection and distribution of rabies virus (RV) in different epidemic areas in China. Methods Brain specimens from animals and suspected patients were collected at the districts of high-, medium- and low incidence rates of human rabies and detected by both direct Immunofluorescence assay (DFA) and RT-PCR. Results 254 of 3007 specimens of dog brains showed RV positive by DFA (positive rate of 8.4% ). Among these 254 samples, 78 showed positive (positive rate of 30.7% ) by RT-PCR. 93 specimens from dogs and cats that had attacked human beings, 63 of them showed positive by DFA (positive rate of 67.7%) and all of them were also positive by RT-PCR. In addition, RV could also be detected in Apodemus agrarius,ferret badger, and suspected patients specimens from the districts under survey. There was no statistical difference between the infection rates of RV in different provinces and regions with different incidence of rabies. Conclusion There might be a relatively high infection rate of RV among the domestic dogs/cats in the endemic areas in China. Wild animals might have been infected with RV in the districts under survey.
