Objective To explore the potential causal relationship between 91 inflammatory factors and the risk of lung cancer (LC). Methods By extracting related data of inflammatory factors and LC and its subtypes from public databases of Genome-wide Association Studies (GWAS), bidirectional, repeated, multivariable Mendelian randomization (MR) and subgroup MR methods were used for analysis. The inverse variance weighted method was mainly used for causal inference, and a series of sensitivity analyses were applied to verify the strength of the results. Results Higher levels of CD5, interleukin-18 (IL-18), and oncostatin-M (OSM) were causally associated with a lower risk of LC, while nerve growth factor-β (NGF-β) and S100 calcium-binding protein A12 (S100A12) were associated with an increased risk of LC. Subgroup MR analysis results showed that IL-18 had a causal relationship with a reduced risk of lung adenocarcinoma, while NGF-β and S100A12 had a causal relationship with an increased risk of lung adenocarcinoma; CD5 and OSM had a causal relationship with a reduced risk of lung squamous cell carcinoma; NGF-β had a causal relationship with an increased risk of small cell lung cancer. Conclusion Five inflammatory factors, including CD5, IL-18, OSM, NGF-β, and S100A12 have a causal correlation with the risk of LC, providing potential targets for early screening of LC patients and development of therapeutic drugs.

Parkinson′s disease (PD) is a neurodegenerative disorder that significantly impacts speech and voice, leading to hypokinetic dysarthria, a motor speech disorder. The advent of artificial intelligence (AI) has opened new avenues for the assessment, diagnosis, and rehabilitation of PD-associated speech impairments. This review explores the application of AI in the study of PD speech disorders, focusing on automated speech analysis, machine learning algorithms, and the development of speech pathology databases. This review also discusses the methodologies and technologies employed, such as speech signal processing, feature extraction techniques, classification algorithms, and the symptoms they can detect, including voice quality, articulation, speech rate, and prosody. The role of AI in early diagnosis, disease progression monitoring, treatment evaluation, and remote rehabilitation is highlighted. The review concludes with a discussion on the potential and challenges of AI in this field and recommendations for future research.

Objective To investigate the clinical curative effect and the influence on knee joint function of knee osteoarthritis treating with sodium hyaluronate combined with compound salvia injection.Methods 78 patients with osteoarthritis treated in our hospital from June 2015 to August 2016 were randomly divided into three groups: sodium hyaluronate group, compound salvia injection group and sodium hyaluronate plus compound salvia injection combination therapy group, 26 cases each group.The levels of serum inflammatory cytokines (IL-6,TNF-αand IL-1β) were measured by ELISA before and after treatment in the three groups, and the improvement of knee joint function and the change of pain score before and after treatment were analyzed as well.Results The total effective rate of sodium hyaluronate combined with compound salvia injection was significantly higher than that of sodium hyaluronate and compound salvia injection alone ( P <0.05 ); after treatment, patients VAS pain score was significantly decreased ( P <0.05), and the VAS pain scores in the combination group were significantly lower than those of the group treated with sodium hyaluronate and the compound salvia injection (P<0.05).The levels of IL-6, TNF-αand IL-1βin the three groups were significantly lower than those before treatment (P<0.05),and the inflammatory factors in the combination group were significantly lower than those in the alone treatment group (P <0.05). Conclusion Sodium hyaluronate combined with compound salvia injection has good clinical curative effect on knee osteoarthritis,improving the function of knee joint, reducing pain and so on.

Objective To investigate the effect of erythropoietin on hemorrhage in hip replacement surgery .Methods 48 cases undergoing elective hip replacement surgery in our hospital From June 2014 to October 2016 were selected and devided into control group and experimental group according to the conditional similarity, 24 cases in each group, then the application of erythropoietin in hip replacement surgery was explored.For the experimental group, erythropoietin was injected subcutaneously at three, five and seven days before operation, the dose was 250 U/(kg· times).The control group received 0.9%sodium chloride injection of the same volume of saline, and the other treatments were the same as in the experimental group.Preoperative situation, hemoglobin (Hb) levels, blood pressure (diastolic pressure and systolic blood pressure) at one day before surgey and three, seven and 14 days after surgey were compared and analyzed.Results There were no significant difference in body weight, hemoglobin (Hb), and age between the two groups before operation.The levels of Hb in the experimental group and the control group at 3 and 7 days after operation were compared, the difference was statistically significant (P<0.05), 14 days after the surgey, Hb returned to normal in the experimental group, while the Hb level in the control group was still significantly lower than that in the control group before surgey, the difference was statistically significant (P<0.05).There was no significant difference in diastolic blood pressure and systolic blood pressure between the two groups.Conclusion Preoperative erythropoietin mobilization in patients with hip replacement surgery can reduce the amount of bleeding during and after operation , and the adverse reactions are not obvious.

Objective To observe the influences of sonophoresis of Fufang Sanqi Xiaotong (Compound Notoginseng Pain-relieving) Ointment on changes of synovial morphology and expressions of chondrocyte caspase-9 and X-linked inhibitor of apoptosis protein (XIAP) in rabbits with knee osteoarthritis (KOA).Methods New Zealand white rabbits (n =32,6 months old) were randomly divided into group of sonophoresis of Fufang Sanqi Xiaotong (sonophoresis group),group of coupling agent ultrasound treatment (coupling agent group),model group and normal group (each n =8).Except of normal group,other groups received anterior cruciate ligament transaction (ACLT).After 6 weeks,sonophoresis group and coupling agent group were given corresponding therapies for 2 treatment courses and model group and normal group were not given any interventions.The changes of synovial histomorphology were observed with light microscope after HE staining,and expressions of caspase-9 and XIAP were detected by using immunohistochemistry technique in all groups after 2 treatment courses.Results The degeneration degree of synovial membrane under light microscope showed an ascending order in all groups as follows:normal group,sonophoresis group,coupling agent group and model group.The value of integral optical density (IOD) of caspase-9 was higher,and IOD value of XIAP was lower in sonophoresis group,coupling agent group and model group than those in normal group.The IOD value of caspase-9 was lower,and IOD value of XIAP was higher in sonophoresis group and coupling agent group than those in model group.The IOD value of caspase-9 was lower,and IOD value of XIAP was higher in sonophoresis group than those in coupling agent group.Conclusion The sonophoresis of Fufang Sanqi Xiaotong is superior to ultrasound treatment,and has the protective effect on cartilage and relief effect on synovial inflammation,and can delay KOA development.The mechanism may be related to decrease of caspase-9 expression and increase of XIAP expression.

There were 482 male patients with non-hyperostosis diagnosed by X-ray among 1207 males who visited West China Hospital because of pain and/or numbness in bone or/and in joints from August 2003 to December 2005; the base-line information in records included age, stature, body weight(calculated BMD, symptoms, co-morbidities, exercise frequency, and smoking. The bone mineral density of lumbar spine was determined and used to judge osteoporosis or non-osteoporosis. Comparison was made on the basic information between osteoporosis group and non-osteoporosis group by t test or chi2 test statistical analysis; the relationship of multiple factors with osteoporosis was analyzed by Logistic Regression. The results of comparison between osteoporosis group and non-osteoporosis group indicated, there were significant differences among BMI, exercise and smoking, but no significant differences were seen among age, complications of hypertension and diabetes mellitus. According to the results of multiple regression analysis, BMI and smoking are the risk factors of osteoporosis, yet exercise is the protection factors of osteoporosis; the risk of osteoporosis increases by 0.654 times in men with BMI scaling up by 1 kg/m2 (P = 0.004). Therefore, we conclude that BMI is a risk factor of osteoporosis in male, and it may be related to body fat distribution.

From among the patients who visited the Dept. of Rehabilitation of West China Hospital for arthalgia in the period from Aug. 2003 to Dec. 2005, we recruited 566 male patients who were over 40 years of age and did not have hyperostosis in the lumbar spine, and whose T scores were each less than--1. Their ages ranged from 40 to 93 years, and the average age was 62.93 +/- 13.50. The dual-energy X-ray absorptiometry from DMS Company in France was used to measure the bone density of the L2-4 anterior-posterior. The basic data about the subjects, containing the age, height, weight, diabetes mellitus, exercise and smoking or not, were recorded. Then the body mass index were calculated. In accordance to the T score, the subjects were separated into two groups: osteopenia group and osteoporosis group. In comparison of the basic data between groups, BMI of osteoporosis group was significantly higher than that of the osteopenia group, but the number of the subjects who exercised was smaller (P < 0.05). Multiple linear regression analysis revealed that in the case BMI increased by 1 kg/m2, BMD significantly decreased by 0.003 g/cm2 (P = 0.002), and the age negatively correlated with BMD (B = -0.001, P = 0.035). "Exercise or not" was positively related to BMD (B = 0.028, P = 0.000). "Smoking or not" and BMD were not significantly correlated (P = 0.837). In conclusion, increase of BMI, or we may say, increase of fat, would decrease the lumbar spine average BMD in the patients of osteoporosis or osteopenia. Some reports have pointed out that only by increasing BMI with increased amount of muscles, but not with increased amount of fat, would be beneficial to the prevention of osteoporosis. So we concluded that the muscle amount in the subjects should be taken into account when we probe into the relation between BMI and BMD.

Previous case-control studies have shown various degrees of inverse correlation between osteoarthritis (OA) and osteoporosis (OP). The aim of this study was to examine the relationship between osteophytes at the cervical , lumbar vertebrae and knee, and the bone mineral density (BMD) of lumbar spine. We analyzed the data on 4091 female patients (aged 13 to 92 years). Osteophyte was defined by X ray examination. BMD of the lumbar spine (LS) was measured by dual energy X-ray absorptiometry (Lunar DPX). The association of osteophytes with BMD and osteophytes at different sites and different degrees were assessed by covariance analysis. Adjustments were made for age and body mass index. The relationship between osteophytes and BMD was analyzed by Binary Logistic Regression. BMD at each site was greater in the female with osteophytes (L4 BMD: P < 0.01, Mean BMD: P < 0.05); the relationship between osteophytes and osteoporosis and that between duration of osteophytes and osteoporosis were inversely correlated (P < 0.01). It confirms the existence of an inverse relationship between osteophytes and OP while a positive relationship is between age, body mass index and osteoporosis.

For the purpose of identifying the effect of body mass index on bone mineral density, an investigation was made in regard to the relationship between body mass index (BMI), bone mineral density (BMD) and bone mineral content (BMC) of lumbar vertebrals of men without osteoporosis. 838 male patients were diagnosed and treated in West China Hospital of Sichuan University because of ostealgia and arthralgia from Aug. 2003 to Dec. 2005. They were examined by dual-energy X-ray absorptiometry, their L2-L4 bone mineral density being < -2.5SD. Then they were graded by body mass index (Kg/m2) [1st group BMI > or =23, 454 cases (Group A BMI > or = 29, 46 cases; Group B 25 < or = BMI < 28.9, 201 cases; Group C 23 < or = BMI < 24, 9193 cases); 2nd group 18.5 < BMI < 22.9, 311 cases; 3rd group BMI < or = 18.5, 68 cases]. The relationships between BMI and BMD of lumbar spine were analyzed using SPSS 13.0. The results revealed their positions in series: (1) Among Groups 1-3, BMD, average BMD and aBMC of L2-L4 being 3rd group > 2nd group > 1st group, the differencs are statistically significant (P < 0.05 or P < 0.01); BMC, aBMC of L3 and L4 and aBMC of L2 being 3rd group > 2nd group > 2nd group, the differences are significant (P < 0.01); besides BMC of L2 and T-score,the differencs among three groups are not statistically significant (P > 0.05); (2) Among the 1st group, BMD and average BMD of L2-L4 being Group C > Group B > Group A,the differencs are significant (P < 0.05 or P < 0.01); BMC, aBMC of L and I being Group C > Group B > Group A,the differences among the three groups are significant (P < 0.05 or P < 0.01); BMC, aBMC of L3 and L4 and aBMC of L2 being Group C > Group B > Group A, the differences are significant, besides BMC of L2 and T-score,the differences among three groups are not significant (P > 0.05), (3) BMI correlated negatively (P < 0.01, r = -0.189) to the average BMD of lumbar spine. The average BMD of lumbar spine decreases when BMI increases in males without osteoporosis. When obesity is more obvious, the decrease in average BMD of lumbar spine bone is more evidently decreased. The decrease of BMD, BMC and total BMC in L3 and L may be greater than that in L2.
