Objective To study the differences in the blood cell analysis of male officers and soldiers be-tween in the high altitude area station and low altitude area station in summer.Methods A total of 239 male officers and soldiers in the high altitude area(Amdo Xizang,average altitude 4 800 m)and 336 male officers and soldiers in the low altitude area(Nanjing,Jiangsu,average altitude 30 m)from July 18 to 24,2022 were selected as the study subjects and the differences in blood cell analysis parameters of male officers and soldiers stationed between at high altitude and low altitude areas were retrospectively analyzed.Results The eosino-phils percentage(EDS％),eosinophils count(EOS)in the high altitude group were significantly lower than thosein the low altitude group(P＜0.05),and the basophillic granulocyte percentage(BASO％),basophillic granulo-cyte count(BASO)and monocyte percentage(MONO％)were significantly higher than those in the low alti-tude group,and the differences were statistically significant(P＜0.05),but which in the both groups were in the normal reference ranges.The red blood cell count(RBC)hemoglobin(Hb)and hematocrit(HCT)in the high altitude group were significantly higher than those in the low altitude group(P＜0.05),moreover Hb and HCT in the high altitude group were in the upper limit of the medical reference range.The mean corpus-cular volume(MCV),mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC)and red blood cell distribution width-standard diviation(RDW-SD)in the high altitude group were lower than those in the low-altitude group(P＜0.05),but the both groups were in the normal reference ran-ges;there was no statistically significant difference in the erythrocyte distribution width coefficient of variation(RDW-CV)between the two groups(P＞0.05).The platelet(PLT)and thrombocytocrit(PCT)in the high altitude group were higher than those in the low altitude group,the platelet distribution width(PDW),mean platelet volume(MPV)and platelet large cell ratio(P-LCR)were lower than those in the low altitude group,and the differences were statistically significant(P＜0.05);PDW in the low-altitude group was at the upper limit of the medical reference range,and the other platelet-related indexes were in the normal range.Conclusion There are obvious differences in the blood cell analysis indicators of male officers and soldiers be-tween the high altitude area and low altitude area.

This experiment aims to study the taste-masking effects of different kinds of corrigent used individually and in combination on ibuprofen oral solution, in order to optimize the taste-masking formulation. Firstly, a wide range of corrigent and the mass fractions were extensively screened using electronic tongue technology. Subsequently, a combination of sensory evaluation, analytic hierarchy process (AHP)-fuzzy mathematics evaluation, and Box-Behnken experimental design were employed to comprehensively assess the taste-masking effects of different combinations of corrigent on ibuprofen oral solution, optimize the taste-masking formulation, and validate the results. The study received ethical approval from the Review Committee of the Beijing University of Chinese Medicine (ethical code: 2024BZYLL0102). The results showed that corrigent fractions and types were screened separately through single-factor experiments. Subsequently, a Box-Behnken response surface design combined with AHP and fuzzy mathematics evaluation was used to fit a functional model: Z = 688.310 11 - 3 023.722 22X₁ - 11.477 00X₂ + 62.721 67X₃ + 14.600 00X₁X₂ - 179.666 67X₁X₃ - 3.152 00X₂X₃ + 4 031.111 11X₁² + 0.525 28X₂² + 9.772 00X₃². This model is stable and reliable, determining the optimal taste-masking formulation to be 3.9 g·L^-1 of stevioside, 100 g L^-1 of xylitol, and 30 g L^-1 of methyl-β-cyclodextrin. The comprehensive score of the verification test is 88.14, with a relative RSD of 0.39%, indicating the feasibility of this model. This study achieved the improvement of the taste of ibuprofen oral solution through a combination of objective and subjective methods. Three types of corrigent were identified for enhancing drug taste, leading to the selection of the optimal taste-masking formulation for ibuprofen oral solution. This significantly enhanced the taste of the original formulation, improved patient compliance, and offered a new approach to mitigating the undesirable taste of formulations.

Objective:To investigate the effect of Early infarct growth rate(EIGR) on the prognosis of patients with acute large vessel occlusive ischemic stroke.Methods:A total of 164 patients with acute large vessel occlusive ischemic stroke were enrolled in the emergency department of the First Affiliated Hospital of Nanjing Medical University from January 1, 2020 to December 31, 2022.According to the change of the National Institutes of Health Stroke Scale (NIHSS) score at admission and 72 h after treatment, the patients were divided into good prognosis group and poor prognosis group. The basic clinical data of the two groups were observed and compared. The risk factors of poor prognosis were analyzed by univariate regression. The effect of EIGR on prognosis after age stratification was further analyzed.Results:Comparing the clinical data of the two groups, there was no difference in EIGR (mL/h) (7.67 vs. 8.24, P=0.211) between the two groups. The product between EIGR and age was included as the interaction term, and the result of the interaction term in the model was statistically significant ( OR=1.002, 95% CI: 1.000-1.003, P=0.032) .Moreover, the result was still statistically significant after adjusting for relevant variables (gender, history of hypertension, history of atrial fibrillation, history of diabetes, history of coronary heart disease, and history of stroke) ( OR=1.002, 95% CI:1.000-1.003, P=0.027). Subgroup analysis was performed according to the median age (71 years). In the elderly group, the proportion of poor prognosis was higher with fast core infarction growth rate defined by 25 mL/h and 15 mL/h ( P < 0.05).In the younger age group, there was no significant difference in the proportion of poor prognosis in the fast core infarction growth rate compared with the slow type ( P > 0.05). Conclusions:EIGR can predict the early clinical outcome early in elderly patients with large vessel occlusive ischemic stroke.

Objective:To evaluate the clinical value of cognitive and motor function in predicting conversion to neurodegenerative disorders in patients with isolated rapid eye movement sleep behavior disorder (iRBD).Methods:Forty-seven patients with iRBD were collected from the Department of Neurology of Tianjin Medical University General Hospital and Tianjin Medical University General Hospital Airport Site during October 2018 and June 2022. All participants received comprehensive evaluations of cognitive and motor function at baseline. The visuospatial function was evaluated by Rey-Osterrieth Complex Figure Test (ROCF)-copy, the memory function was evaluated by Auditory Verbal Learning Test and ROCF-recall, the attention-executive function was evaluated by Trail Making Test (TMT) and Stroop Color-Word Test, and the language function was evaluated by Boston Naming Test. The motor function was evaluated by Unified Parkinson′s Disease Rating Scale-Ⅲ, Alternate-tap Test (ATT), and 3-meter Timed Up and Go Test. The iRBD patients with phenoconversion were identified during follow-up. Receiver operating characteristic curve and generalized linear model Logistic regression were applied to identify the optimal combination of cognitive and motor tests in distinguishing the converters from non-converters in patients with iRBD. Multivariate Cox regression analyses were applied to evaluate the independent risk factors in predicting conversion to neurodegenerative diseases in patients with iRBD.Results:The median follow-up duration was 3 years. Forty-five iRBD patients were included in the analysis eventually, as 2 dropped out at follow-up. Twenty-one iRBD patients developed neurodegenerative disorders, with 14 presenting motor phenotype and 7 cognitive phenotype. Baseline ROCF-copy, TMT-A and ATT were best combination in identifying iRBD patients with phenoconversion [sensitivity: 90.0%, specificity: 87.5%, area under curve (AUC): 0.931, P<0.001]. Baseline TMT-A and ATT were best combination in identifying iRBD patients with motor phenotype conversion (sensitivity: 100.0%, specificity: 66.7%, AUC: 0.872, P<0.001); Baseline TMT-A performed best in identifying iRBD patients with cognitive phenotype conversion (sensitivity: 83.3%, specificity: 91.7%, AUC: 0.917, P<0.001). Multivariate Cox regression analysis showed that individuals with poorer performance of TMT-A (cut-off value: 63.0 s) and ATT (cut-off value: 205.5 taps/min) than the cut-off values at baseline had higher risks for developing to neurodegenerative disorders, with HR values of 5.455 (95% CI 1.243-23.941, P=0.025) and 11.279 (95% CI 1.485-85.646, P=0.019), respectively. Conclusions:In iRBD, ROCF-copy, TMT-A and ATT served as optimum combination in predicting phenoconversion, whereas TMT-A and ATT served as optimum combination in predicting motor phenotype, and TMT-A performed best in predicting cognitive phenotype. The performance in TMT-A and ATT in iRBD could predict the risk of developing to neurodegenerative disorders independently.

Objective:To explore the influence of environment temperature on the incidence of testicular torsion.Methods:We collected the clinical data on 172 cases of testicular torsion diagnosed in the Second Hospital of Hebei Medical University from De-cember 2013 to December 2020.According to the local environment temperature on the day of onset,we divided the patients into groups A(below 0℃),B(0-10℃),C(10-20℃)and D(above 20℃),and compared the incidence rates of testicular torsion among the four groups,followed by correlation analysis.Results:The incidence rate of testicular torsion was 12.8％(n=22)in group A,35.5％(n=61)in B,34.9％(n=60)in C and 16.9％(n=29)in D,the highest at 0-10℃ in group B,with sta-tistically significant difference among the four groups(x2=29.07,P＜0.001).Spearman correlation analysis indicated that the inci-dence of testicular torsion was negatively correlated with the environment temperature(r=-0.261,P＜0.01),with no statistically significant difference among different seasons(x2=5.349,P＞0.05),but higher in autumn and winter than in the other two sea-sons.Conclusion:The incidence of testicular torsion is negatively correlated with the environment temperature,elevated when the temperature decreases,but has no statistically significant difference among different seasons,though relatively higher in autumn and winter.

Objective:To assess the deformation of the bladder-neck opening and the impact of the bladder-neck angle(BNA)on urination in male patients by fluid-structure interaction(FSI)analysis.Methods:We established geometric models of the blad-der,prostate and urethra were established,incorporating both normal and enlarged BNAs,and assessed the effects of BNA alteration on urinary flow by FSI simulation of the flow rate and pressure of the urine within the bladder,bladder neck and urethra,and that of pros-tate displacement as well.We retrospectively analyzed the clinical data on 145 male patients from the Second Hospital of Hebei Medical University between June 2020 and June 2023,39 with acute urine retention(the AUR group)and 106 without(the non-AUR group),and evaluate the impact of BNA on urination based on the urinary flow rate and prostate volume.Results:Comparative simulation a-nalysis showed significant differences in the total urethral pressure and flow rate between the normal and enlarged BNA models(P＜0.05).The maximum prostate displacement was found at the bladder neck,with moderate displacement and unchanged urethral diame-ter in the normal BNA model,but significant displacement and a reduced urethral opening diameter in the enlarged BNA model.FSI analysis confirmed an evident impact of enlarged BNA on urination,more significant in the AUR than in the non-AUR patients(P＜0.05).The BNAs in the patients with the maximum urinary flow rate(Qmax)of＜10,10-15 or＞15 ml/s were 83.7°±2.5°,67.5°±1.8° and 65.1°±4.8° respectively,with statistically significant difference between the former one and the latter two groups(P＜0.05).The BNAs in the patients with normal prostate volume or BPH of grade Ⅰ,Ⅱ,Ⅲ or Ⅳ were 65.0°±3.7°,67.2°±3.1°,71.5°±2.0°,82.8°±3.5° and 105.8°±6.0°,respectively(P＜0.05),with statistically significant difference between BPH grades Ⅲ and Ⅳ(P＜0.05)as well as between these two and the other three groups(P＜0.05),but not among the normal prostate volume,BPH grade Ⅰ and BPH grade Ⅱ groups(P＞0.05).Spearman correlation analysis indicated that BNA was strongly correlated with total prostate volume(TPV),transition zone volume(TZV),intravesical prostatic protrusion(IPP),prostatic urethral angle(PUA),IPSS,and Qmax(P＜0.05).Conclusion:Changes in BNA affect urination and are closely associated with the se-verity of prostate hyperplasia.The BNA may be an important anatomical factor for assessing the severity of lower urinary tract symptoms in BPH patients.

The oyster mushroom(Pleurotus spp.)is one of the most widely cultivated mushroom species globally.The present study investigated the effect of synbiotics on the growth and quality of Pleurotus ostreatus and Pleurotus pulmonarius.Different synbiotics formulations were applied by spraying mushroom samples daily and measuring their growth parameters,yield,biological efficiency,proximate composition,mineral content,total phenolic content(TPC),and diphenyl-1-picryl-hydrazyl(DPPH)radical scavenging activity.Results demonstrated that the most significant yield of oyster mushrooms was harvested from synbiotics sprayed with inulin and Lactobacillus casei(56.92 g).Likewise,the highest biological efficiency obtained with a similar synbiotic was 12.65%.Combining inulin and L.casei was the most effective method of improving the mushrooms'growth performance and nutrient content in both samples.Furthermore,synbiotics that combined inulin and L.casei resulted in the highest TPC(20.550 mg gallic acid equivalent(GAE)/g dry extract(DE))in white oyster mushrooms(P.ostreatus).In comparison,in grey mushroom(P.pulmonarius)the highest TPC was yielded by L.casei(1.098 mg GAE/g DE)followed by inulin and L.casei(1.079 mg GAE/g DE).The DPPH results indicated that the oyster mushroom could be an efficient antioxidant.The results revealed that applying synbiotics improved the mushrooms'quality by increasing their antioxidant capacity with higher amounts of phenolic compounds and offering better health benefits with the increased levels of mineral elements.Together,these studies demonstrated the potential of using synbiotics as a biofertilizer,which is helpful for mushroom cultivation;therefore,it might solve the challenge of inconsistent quality mushroom growers face.

Objective To evaluate the long-term efficacy of tumor necrosis factor-α(TNF-α)inhibitor(TNFi)in the treatment of ankylosing spondylitis(AS)complicated with osteoporosis(OP)and the impact on bone metabolism,bone density,and inflammatory factors.Methods The data of 158 patients with AS and OP,who were admitted to Department of Rheumatology and Immunology of The First Affiliated Hospital of Naval Medical University(Second Military Medical University)from Jan.1,2010 to Dec.31,2017,were retrospectively collected.The patients were divided into bisphosphonate group(n=54),TNFi group(n=58),and TNFi+bisphosphonate group(n=46)according to the treatment methods.All patients were treated with calcium combined with calcitriol as the background treatment.After 5 years of treatment,Bath ankylosing spondylitis disease activity index(BASDAI)and Bath ankylosing spondylitis functional index(BASFI)scores were evaluated,and inflammatory indexes,bone metabolism markers,and bone mineral density were detected.Results After 5 years of treatment,the BASDAI and BASFI scores,erythrocyte sedimentation rate(ESR),C reactive protein(CRP),TNF-α,and interleukin-17A of the TNFi+bisphosphonate group and TNFi group were significantly lower than those before treatment(all P＜0.05);in the bisphosphonate group only ESR and CRP were significantly lower than those before treatment(both P＜0.05),and the other inflammatory indexes and BASDAI and BASFI scores showed no significant changes(all P＞0.05).The bone mineral density of the 3 groups after 5 years of treatment was significantly higher than that before treatment(all P＜0.05),and the bone mineral density of the TNFi+bisphosphonate group was significantly higher than that of the other 2 groups(both P＜0.05).After 5 years of treatment,the levels of parathyroid hormone(PTH),procollagen type 1 N-terminal propeptide(P1NP)and β-C-terminal telopeptide of type Ⅰ collagen(β-CTX)in the TNFi+bisphosphonate group and bisphosphonate group were significantly decreased compared with those before treatment(all P＜0.05),while the levels of N-terminal midfragment of osteocalcin(N-MID)and 25-hydroxy-vitamin D(25VitD)were significantly increased(all P＜0.05);in the TNFi group only PTH and P1NP levels were significantly decreased(both P＜0.05),while β-CTX,N-MID and 25VitD levels showed no significant differences(all P＞0.05).Conclusion Long-term use of TNFi in patients with AS and OP can effectively reduce disease activity,improve physical function,decrease the level of inflammatory factors,alleviate abnormal bone metabolism,and increase bone mineral density;and the combined use of TNFi and bisphosphonates has better efficacy.

Background and objective The incidence rate of lung cancer in Xuanwei has been continuously in-creasing in recent years,and it also features high incidence across all age groups and high mortality rates among female lung cancer patients.Therefore,the search for more stable biomarkers for the diagnosis of Xuanwei lung cancer holds tremendous clinical application prospects.This study aims to explore the clinical application value of these four microRNAs(miRNAs)in-dividually and in combination with traditional lung cancer tumor markers in the detection and diagnosis of Xuanwei lung can-cer.Methods By detecting the expression levels of four miRNAs and five traditional lung cancer tumor markers in the serum of 45 Xuanwei lung cancer patients and healthy physical examination participants,the Logistic regression model was employed to comprehensively evaluate the sensitivity,specificity,diagnostic efficacy,and other relevant statistical indicators of the four miR-NAs in the diagnosis of Xuanwei lung cancer.Results Among the individual miRNAs,miR-4646-5p and miR-3654 showed significant differences in expression levels between the Xuanwei lung cancer group and the control group(P＜0.05).miR-3654 demonstrated the best diagnostic performance with a sensitivity of 86.7％ ,specificity of 82.2％ ,and an area under the curve of 0.847.Combining miR-3654 with miR-4646-5p and carcinoembryonic antigen(CEA)resulted in the highest diagnostic ef-ficacy for Xuanwei lung cancer,with a sensitivity of 73.3％ ,specificity of 93.3％ ,area under the curve of 0.901,and a positive predictive value of 91.7％ .Conclusion Among the four miRNAs,serum miR-3654 exhibits the best diagnostic efficacy for Xuanwei lung cancer.Combined with miR-4646-5p and CEA,its diagnostic value for Xuanwei lung cancer can be effectively enhanced,making it a promising screening indicator for Xuanwei lung cancer.

OBJECTIVE: To compare the therapeutic effect between Hunyuan moxibustion and oral western medication on diarrhea-predominant irritable bowel syndrome（IBS-D）of spleen and kidney yang deficiency. METHODS: Sixty patients with IBS-D of spleen and kidney yang deficiency were randomly divided into a Hunyuan moxibustion group and a western medication group, 30 cases each group. The Hunyuan moxibustion group was treated with Hunyuan moxibustion at Guanyuan（CV 4），40 min each time, once a day; in the western medication group，loperamide hydrochloride capsules (2 mg each time, 3 times a day) and bacillus licheniformis live capsules (0.5 g each time, 3 times a day) were given orally.Both groups were treated for 20 days. The scores of irritable bowel syndrome（IBS）symptom severity scale（IBS-SSS）, IBS quality of life scale (IBS-QOL) and TCM symptom grading quantitative were observed before and after treatment, and the clinical efficacy and safety were evaluated in the two groups. RESULTS: After treatment，each item scores and total scores of IBS-SSS in the two groups were lower than those before treatment（P<0.05）, and the total scores of IBS-QOL were higher than those before treatment (P<0.05)；each item score and total score of IBS-SSS in the Hunyuan moxibustion group were lower than those in the western medication group (P<0.05), and the total score of IBS-QOL in the Hunyuan moxibustion group was higher than that in the western medication group (P<0.05).After treatment, each item score and total score of TCM symptom grading quantitative in the Hunyuan moxibustion group were lower than those before treatment (P<0.05), the abdominal pain, diarrhea, lack of appetite scores and total score in the western medication group were lower than those before treatment (P<0.05)；and the abdominal pain, soreness and weakness of waist and knees, fear to cold and cold limbs scores and total score in the Hunyuan moxibustion group were lower than those in the western medication group (P<0.05).The total effective rate was 90.0%（27/30）in the Hunyuan moxibustion group, which was higher than 73.3%（22/30）in the western medication group (P<0.05). No adverse reactions occurred in both groups during treatment. CONCLUSION Hunyuan moxibustion can effectively improve the symptom severity and quality of life in patients with IBS-D of spleen and kidney yang deficiency, especially in improving the symptoms of abdominal pain, soreness and weakness of waist and knees, fear to cold and cold limbs.Its therapeutic effect is superior to western medication.
