Objective Pulmonary oxygen poisoning resulting from hyperbaric oxygen,frequently occurs in specialized operations,without any current effective prevention or treatment measures.To elucidate the impact and mechanism of neostigmine(NEO)in combination with anisodamine(ANI)(neoscopolamine)on pulmonary oxygen toxicity.Methods The animal model of pulmonary oxygen poisoning was established.C57BL/6 mice were exposed to 2.5 ATA 99.9%oxygen for 6 h.The control group mice were injected with normal saline ip,while the treatment group mice received injections of ANI(25 mg/kg,ip)and NEO(50 μg/kg,ip).Lung tissues were collected and stained with HE to observe any pathological injuries after exposure.Evans blue stain was utilized to identify lung permeability,wet/dry lung ratio,and protein concentration in the bronchoalveolar lavage fluid(BALF)to assess the lung injury's severity.The modifications in inflammatory factors,oxidative stress indicators,and iron content in lung tissue were assessed.Results The results showed that the 2.5 ATA 99.9%oxygen-exposed group experienced a significant worsening of lung injury,as well as increased lung permeability,lung wet/dry ratio,and protein content in alveolar lavage fluid when compared to the control group.Moreover,mRNA levels of pro-inflammatory cytokines IL-1β,IL-6,TNF-α,and IFN-γ in the lung tissue of the model group were significantly elevated,while the levels of anti-inflammatory cytokines IL-4 and TGF-β were significantly reduced.The oxidative index MDA also significantly increased,while the antioxidant index GSH significantly decreased.Additionally,the expression of GPX4,a marker of ferroptosis,increased with an increase in iron content.Neoscopolamine treatment successfully reversed those effects.Conclusion The combined use of ANI and NEO had a protective effect on pulmonary oxygen poisoning.Neoscopolamine may inhibit inflammation and oxidative stress by activating the cholinergic anti-inflammatory pathway,thereby reducing the content of free iron in lung tissue and finally inhibiting cell ferroptosis.

Objective:To analyze the epidemic characteristics of reported tuberculosis incidence in Kashgar from 2015 to 2022, and use the seasonal autoregressive integrated moving average (SARIMA) model to predict the incidence, providing references for the local control of pulmonary tuberculosis.Methods:The reported incidence data of tuberculosis in the Kashgar area of Xinjiang from January 2015 to August 2023 were collected through the"Infectious Disease Monitoring System", a subsystem of the "Chinese Disease Prevention and Control Information System". The epidemic characteristics of reported incidence in this area from 2015 to 2022 were analyzed. Two SARIMA models of monthly reported incidence number and rate were established. The prediction performance of the two models was evaluated using the reported incidence data of tuberculosis from January 2023 to August 2023. The χ2 test was used to analyze population characteristics, and the Cochran-Armitage trend test was used to analyze annual incidence. Results:From 2015 to 2022, 133 972 cases of pulmonary tuberculosis were reported in Kashgar, with a yearly reported incidence rate of 383.64/100 000, showing a rising trend ( TCA=77.03, P<0.001) and then a declining trend ( TCA=176.16, P<0.001). The proportion of pathogenic positive pulmonary tuberculosis had increased yearly ( TCA=132.66, P<0.001). The reported onset time was concentrated from January to June each year, with a peak in April. Yengisar County, Zepu County and Yopurga County had the highest reported incidence rate in Kashgar. The sex ratio of men to women was 1.03∶1, and the reported incidence rate of men was higher than that of women ( χ2=27.04, P<0.001). The reported incidence rate of the group aged 60 years and older was the highest. The patient′s occupation was mainly farmers (84.99%). The average relative errors of the SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model in predicting the reported monthly incidence number and rate were 11.67% and -9.81%, respectively. Both models had good prediction accuracy (MAPE=33.55%, MAPE=38.22%). Conclusion:The average reported incidence rate of pulmonary tuberculosis in the Kashgar area shows a rising trend first and then a declining trend. The patients are mainly men and farmers, and attention should be paid to the prevention and control of tuberculosis among the elderly in winter and spring. The SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model can fit the trend of reported tuberculosis incidence in the Kashgar area well and have good predictive performance.

Objective:To observe the effect of Fangji Huangqitang （FJHQT） on collagen induced arthritis （CIA） and synovial angiogenesis in DBA/1 mice. Method:DBA/1 mice were randomly divided into normal group， CIA group and FJHQT group. DBA/1 mice in CIA group and FJHQT group were immunized with bovine type Ⅱ collagen and complete Freund's adjuvant on the first day， and DBA/1 mice were immunized with bovine type Ⅱ collagen and incomplete Freund's adjuvant on the 21^st day to establish CIA model. On the day of the second immunization， the drug was given by gavage once a day for 28 days. On the 22^nd day， the arthritis score and other symptoms of CIA mice were observed. On the 49^th day， Hematoxylin eosin （HE） staining was carried out to observe the angiogenesis in the synovium of CIA mice， the expression of vascular endothelial cell marker platelet endothelial cell adhesion molecule-1 （CD31） and vascular endothelial growth factor （VEGF） in the synovium of CIA mice were detected. Immunofluorescence double staining was used to detect the mature and immature vessels in the synovium of CIA mice. And the microvascular growth of the rat thoracic aortic ring was induced by VEGF （20 μg·L^-1）. The effects of FJHQT （0.25， 0.5， 1 g·L^-1） at different concentrations were observed under microscope. Result:Compared with the normal group， the inflammation， joints， red and swelling of the inflammatory joints of the CIA group were significantly increased （P<0.01）. The scores of clinical arthritis， the incidence rate， synovial inflammation and angiogenesis were significantly increased （P<0.01）. The density of blood vessels， the positive expression of CD31 and VEGF， the number of immature vessels in synovial membrane were significantly increased （P<0.01）. And compared with the CIA group， the inflammation， joint swelling， and malformation of the FJHQT group were significantly improved， the clinical arthritis score， incidence rate， synovial inflammation and angiogenesis were significantly reduced （P<0.01）. The vascular density， the positive expression of CD31 and VEGF， and the number of immature blood vessels in synovial membrane were significantly increased （P<0.01）. Compared with blank group， VEGF could significantly induce the growth of microvasculature in rat thoracic aortic ring （P<0.01）. Compared with VEGF group， FJHQT（0.25， 0.5， 1 g·L^-1） could significantly inhibit the formation of microvasculature in rat thoracic aortic ring （P<0.01）. Conclusion:FJHQT can effectively alleviate the clinical symptoms and condition of CIA mice， reduce the clinical arthritis score and incidence rate，and inhibit the synovial angiogenesis of CIA mice joints and VEGF induced microvascular formation in rat thoracic aortic rings.

Fucoidan(FPS) is an effective component of the Chinese patent medicine named Haikun Shenxi, which treats schronic renal failure in clinics, and has the potential anti-aging effects. However, it is still unclear whether FPS can improve renal aging, especially the molecular mechanism of its anti-aging. The human proximal renal tubular epithelial cells(HK-2) in vitro were divided into normal group(N), D-gal model group(D), low dose of FPS group(L-FPS), high dose of FPS group(H-FPS) and vitamin E group(VE), and treated by the different measures, respectively. More specifically, the HK-2 cells in each group were separately treated by 1 mL of 1% fetal bovine serum(FBS) or D-galactose(D-gal, 75 mmol·L~(-1)) or D-gal(75 mmol·L~(-1))+FPS(25 μg·mL~(-1)) or D-gal(75 mmol·L~(-1))+FPS(50 μg·mL~(-1)) or D-gal(75 mmol·L~(-1))+VE(50 μg·mL~(-1)). After the treatment for 24 h, firstly, the effects of D-gal on senescence-associated β-galactosidase(SA-β-gal) staining characteristics and klotho, P53 and P21 protein expression le-vels, as well as adenosine monophosphate activated protein kinase(AMPK)-uncoordinated 51-like kinase 1(ULK1) signaling pathway activation in the HK-2 cells were detected, respectively. Secondly, the effects of FPS and VE on SA-β-gal staining characteristics and klotho, P53 and P21 protein expression levels in the HK-2 cells exposed to D-gal were investigated, respectively. Finally, the effects of FPS and VE on microtubule-associated protein 1 light chain 3(LC3) protein expression level and AMPK-ULK1 signaling pathway activation in the HK-2 cells exposed to D-gal were examined severally. The results indicated that, for the HK-2 cells, the dose of 75 mmol·L~(-1) D-gal could induce the changes of SA-β-gal staining characteristics and klotho, P53 and P21 protein expression levels. That is causing cells aging. FPS and VE could both ameliorate the changes of SA-β-gal staining characteristics and klotho, P53 and P21 protein expression levels in the HK-2 cells exposed to D-gal. That is anti-cells aging, here, the functions of FPS and VE are similar. D-gal could not only induce cell aging but also increase LC3Ⅱ, phosphorylated-AMPK(p-AMPK) and phosphorylated-ULK1(p-ULK1) protein expressions, and activate autophagy-related AMPK-ULK1 signaling pathway. FPS and VE could both improve the changes of LC3Ⅱ, p-AMPK and p-ULK1 protein expression levels in the HK-2 cells exposed to D-gal. That is inhibiting autophagy-related AMPK-ULK1 signaling pathway activation. On the whole, for the human proximal renal tubular epithelial cells aging models induced by D-gal, FPS similar to VE, can ameliorate renal cells aging by possibly inhibiting autophagy-related AMPK-ULK1 signaling pathway activation. This finding provides the preliminary pharmacologic evidences for FPS protecting against renal aging.

Scutellariae Radix(Huangqin) is a well-known traditional Chinese medicine(TCM) used for the treatment of clearing heat in clinical application. It is bitter-cold by using directly, but the bitter-cold property can be relieved after wine-frying. The study of taste changes before and after wine-frying of Scutellariae Radix is of great significance in identifying Scutellariae Radix and wine-processed Scutellariae Radix and clarifying the traditional theory of wine-processing. In this experiment, 10 batches of Scutellariae Radix and wine-processed Scutellariae Radix were prepared. The contents of 5 flavonoids were determined by high performance liquid chromatography(HPLC), and principal component analysis(PCA) was performed with 5 flavonoids as variables. As a result, the contents were different in different batches of Scutellariae Radix, but Scutellariae Radix and wine-processed Scutellariae Radix could not be distinguished. Five sensory attributes(sour, salty, fresh, sweet, and bitter) were evaluated by artificial tasting, and the response values of 7 sensors(AHS, AHS, PKS, CTS, NMS, CPS, ANS, SCS) representing the taste of pieces were detected by electronic tongue. The correlation between sensory evaluation and response values of the electronic tongue were analyzed, and the results showed that the sensory evaluation of sour, salty, fresh, sweet, bitter and AHS, CTS, NMS, ANS, SCS sensors had different degrees of correlation, indicating that the electronic tongue technology can be used as an alternative to artificial taste and can serve as a means for quantifying the taste, and it can be used to evaluate the taste of TCM pieces. The taste method was used to analyze the response values of the electronic tongue, and the results showed that the bitterness of wine-processed Scutellariae Radix decreased and the salty taste increased. PCA was used to analyze taste changes before and after wine-processed Scutellariae Radix, and the results showed that taste differences between 2 pieces were divided into 2 categories. PCA loading scattering plots showed that response of saltiness and bitterness were the major factors to affect overall taste in Scutellariae Radix and wine-processed Scutellariae Radix. Based on electronic tongue response values, the Fisher discriminant model for Scutellariae Radix and wine-processed Scutellariae Radix was established, which showed that it could effectively discriminate them with a recognition rate of 100%. The experimental results showed that the electronic tongue combined with multivariate statistical analysis can be used to evaluate taste of TCM, at the same time, it could provide a fast and simple method for identifying different processed products.

The quality of traditional Chinese medicine tablets is correlated with clinical efficacy and drug safety, and plays a great role in promoting the development of traditional Chinese medicine. However, the existing traditional artificial identification and modern instrument detection in terms of accuracy and timeliness have both advantages and disadvantages. Therefore, how to quickly and accurately identify the quality of traditional Chinese medicine tablets has become a high-profile issue. The purpose of this paper is to explore the feasibility of the application of electronic eye technology in the study of rapid identification of traditional Chinese medicine quality. A total of 80 batches of samples were collected and tested by Fritillariae Cirrhosae Bulbus for traditional empirical identification(M_1) and modern pharmacopeia(M_2). The optical data was collected from electronic eyes, and the chemical metrology was used to establish suitable discrimination models(M_3). Four authenticity and commodity specification models, namely identification analysis(DA), minimum bidirectional support vector machine(LS-SVM), partial minimum two-multiplier analysis(PLS-DA), main component analysis identification analysis(PCA-DA), were established, respectively. The accuracies of the authenticity identification models were 82.5%, 90.0%, 96.2% and 93.8%, while the accuracies of the commodity specification identification models were 89.3%, 96.0%, 90.7% and 97.3%, respectively. The models were well judged, the authenticity identification was based on the final identification model of PLS-DA, and the commodity specification was based on the final identification model of PCA-DA. There was no significant difference between its accuracy and M_1, and the time of determination was much shorter than M_2(P<0.01). Therefore, electronic-eye technology could be used for the rapid identification of the quality of Fritillariae Cirrhosae Bulbus.

OBJECTIVES: To analyze the characteristics of medical malpractices in orthopaedic surgeries, to explore principles and methods in medical legal identification, and to provide basic data for uniform medicolegal standard for the future medical identification. METHODS: A retrospective analysis was conducted on 100 cases of medical malpractices in orthopaedic surgery, among the 364 cases archived in Medicolegal Expertise Center of Xi'an Jiaotong University during 2002-2015. RESULTS: In the 100 cases of orthopedic medical malpractices, with 104 hospitals involved in, 95 cases were judged with medical errors and the other 9 cases with no error. The top 3 reasons for errors were （1） inadequate observation or estimation of diseases （27.9%）, （2） intraoperative improper operation （17.3%）, and （3） delayed or missed diagnosis and treatment （12.5%）. The consequences of medical malpractices were mostly disability （61%）, followed by prolonged diseases （31%） and death （8%）. With regard to the causal relationship between medical errors and consequences, 95 cases （91.4%） were with causality and the other 9 cases （8.6%） with no causality. Specifically, 56 cases （53.9%） were with medical errors as the secondary causes accounting for 25% causative potency, and 20 cases （19.2%） were with medical errors as the major causes accounting for 75% causative potency. CONCLUSIONS It is pivotally important for determining the causative potency of medical errors to analyse the causes of damages in orthopaedic surgery and to distinguish subjective factors from objective ones of medical errors.
