Kounis syndrome is an acute coronary syndrome triggered by an allergic reaction, which is clinically rare and frequently subject to misdiagnosis or missed diagnosis. This article presents a case report of a 70-year-old male patient who developed a rash, pruritus, and chest pain following colon polyp resection. Coronary angiography revealed occlusion of the left anterior descending artery, and blood flow was restored after stent implantation. However, the patient experienced recurrent symptoms accompanied by loss of consciousness. Drug skin tests confirmed positive reactions to chlorhexidine and fondaparinux sodium, leading to a diagnosis of type Ⅱ Kounis syndrome. By avoiding allergenic drugs and combining antihistamines with symptomatic treatment to correct myocardial ischemia, the patient′s clinical symptoms significantly improved, and he eventually recovered and was discharged from the hospital. This case underscores the importance of maintaining vigilance for this syndrome in patients with allergies accompanied by chest pain and promptly identifying and avoiding allergens.

Sarcomatoid carcinoma of the renal pelvis accounts for a very low percentage of malignant tumors in the renal pelvis and has a poor prognosis. This article reported a patient with sarcomatoid carcinoma of the renal pelvis. The patient presented with macroscopic hematuria as the first symptom, and CT suggested left renal occupancy, unilateral nephrectomy was performed, and pathology suggested sarcomatoid carcinoma of the renal pelvis. Three weeks after surgery, a follow-up CT showed tumor recurrence. Programmed death 1(PD-1)inhibitor was given once every 3 weeks. Repeated CT examination after 24 weeks of continuous treatment suggested that the recurrent tumor disappeared. The patients was followed-up for 42 months without tumor recurrence or metastasis.

Objective To explore the improving effect of eicosapentaenoic acid(EPA)on the skeletal muscle insulin resistance in obese rats by regulating the p38 MAPK signaling pathway.Methods Fifty male Wistar rats were randomly divided into the control group,model group,inhibitor group,EPA group and inhibi-tor+EPA group,10 cases in each group.The intervention lasted for 6 weeks.The inhibitor group was given 1 mg/kg p38 MAPK inhibitor SB203580 by gavage.The EPA group was given 70 mg/kg EPA by gavage,the in-hibitor+EPA group was given SB203580+EPA by gavage,and the model group and control group were given equal volume of saline.The levels of fasting blood-glucose,fasting serum insulin,glutathione peroxidase(GSH-Px),superoxide dismutase(SOD)and malondialdehyde(MDA)in the skeletal muscles were deter-mined.The rat insulin resistance degree was evaluated by using the intraperitoneal glucose tolerance test(IPGTT)and insulin tolerance test(ITT).The protein and mRNA expression levels of phosphorylation p38 in the rat skeletal muscle tissues were detected by Western blot and qRT-PCR.Results Compared with the control group,the body weight,epididymal fat wet weight,fasting blood-glucose and insulin levels,IPGTT and ITT blood glucose levels,and MDA content in the model group were significantly increased,the GSH-Px and SOD activities were significantly decreased,and the relative expression levels of p-p38 protein and p38 mRNA expression in skeletal muscle tissues were significantly increased(P＜0.05).Compared with the model group,the body weight and epididymal fat wet weight in the EPA group and inhibitor+EPA group were sig-nificantly decreased,while the fasting blood-glucose,fasting serum insulin,IPGTT and ITT blood glucose lev-els and MDA contents in the inhibitor group and EPA group were significantly decreased,the activities of GSH-Px and SOD were significantly increased,and the relative expression level of p-p38 protein in skeletal muscle tissues was significantly decreased(P＜0.05).However,the expression of p38 mRNA in skeletal muscle tissues had no significant change(P＞0.05).Conclusion EPA alleviates the oxidative stress possibly by inhibiting p38 MAPK signaling pathway,thus improves the skeletal muscle insulin resistance of obese rats.

Objective:To investigate the impact of group-based rehabilitation exercise on motor and non-movement symptoms of Parkinson's disease(PD).Methods:A total of 88 patients from out-patient and in-patient services at our hospital were randomly assigned to an early exercise group(E-EG), a late exercise group(L-EG), and a control group(CG)using a randomized delayed-start design.Patients in the E-EG carried out a rigorous, formal group exercise program, one hour per session, twice per week, for 18 months(May 2018-November 2019). Patients in the L-EG took part in the exercise program in the final 6-12 months of the study.We assessed outcomes using the Unified Parkinson's Disease Rating Scale(UPDRS), Parkinson's disease questionnaire-39(PDQ-39 Q), trail-making test part A & B, nine-hole peg test(9-HPT), 30 second sit to stand test(30s SST), 10 m walk test(10 m W), mini-balance evaluation systems test(Mini-BEST), Fullerton Advanced Balance(FAB)Scale and time up and go(TUG)test.Results:Compared with pre-exercise levels, patients with PD in the E-EG had lower performance in UPDRS(17.5±8.3 vs.20.0±8.6, t=-2.2, P=0.02)and lower performance in PDQ-39(27.2±2.1 vs.29.0±9.8, t=-2.6, P=0.001)after exercise.Moreover, compared with pre-exercise levels, patients with PD in the E-EG showed decreased post-exercise performance in trail-making test part B(114.2±25.5 vs.129.8±28.4, t=-2.3, P=0.02)and in 9-HPT(33.7±7.3 vs.39.6±9.3, t=-2.6, P=0.001). Conclusions:The practice of group-based rehabilitation exercise can improve movement abilities and quality of life in PD patients, especially if implemented early.Targeted rehabilitation exercise should be taken as part of the treatment strategy for PD patients as early as possible to deliver the best benefits.

Articular cartilage injury is common in orthopedics. Improper exercises and physical trauma can lead to the injury of cartilage. Since articular cartilage lacks blood supply, once damaged, it is difficult for the cartilage to repair itself. If not treated effectively, cartilage injuries will develop into severe osteoarthritis affecting the whole joint. Arthroscopic microfracture technique can achieve better therapeutic effects than regular joint debridement, with simple procedures, minimal invasion, and low cost. However, the microfracture technique is limited by the patients′ age (under 45 years old) and the size of the cartilage defect area (less than 4 cm 2) Additionally, postoperative patients need to conduct strict and long-term rehabilitation trainings. Generally speaking, the short-term prognosis of microfracture is satisfactory. However, the repair tissue is mainly composed of fibrocartilage, which is inferior to hyaline cartilage because of its poor mechanical properties and anti-wear abilities. Therefore, the long-term effect is controversial. To conclude, arthroscopic microfracture is a recommended method for young patients with small cartilage defect areas, but its exact long-term clinical effects still need to be verified by further research. This paper reviews the operation protocol, clinical efficacy, and the mechanism of arthroscopic microfracture surgery, and aims to provides theoretical basis for its application in clinical treatment.

Objective: To study the effects of Xiaoyaosan on sexual behavior and inflammatory factors of rat with depression. Methods: The establishing depressive rat models of chronic mild unpredictable stress were established. The rats were randomly divided into model group and Xiaoyaosan group, 15 in each group. The Xiaoyaosan group was given 4.612 5 g/(kg•d) Xiaoyaosan, the blank group and the model group were intragastrically administered with normal saline once daily. After 4 weeks of oral administration, mount frequency and perineal licking numbers to female rats in each experimental group were observed by sexual behavior experiment, and the spleen index and thymus index were calculated. The serum DA, IL-1β, IL-6 levels were tested by Elisa. Results: Compared with the normal group, the mount frequency (4.42 ± 3.91 vs. 11.58 ± 6.54), perineal licking numbers (3.53 ± 3.29 vs. 16.36 ± 10.68) and serum DA levels (14.14 ± 0.71 pg/ml vs. 17.44 ± 4.06 pg/ml) in the model group significantly decreased (P<0.05 or P<0.01), and the thymus index (0.012 4 ± 0.001 8 vs. 0.009 3 ± 0.001 7), serum IL-1β (39.45 ± 11.98 pg/ml vs. 28.62 ± 6.61 pg/ml), IL-6 levels (9.74 ± 1.49 pg/ml vs. 6.40 ± 0.66 pg/ml) significantly increased (P<0.05 or P<0.01). Compared with the model group, the contents of serum DA in Xiaoyaosan group (15.90 ± 1.24 pg/ml vs. 14.14 ± 0.71 pg/ml) increased significantly (P<0.01), and the thymus index (0.009 9 ± 0.001 3 vs. 0.012 4 ± 0.001 8) and IL-6 levels (8.32 ± 0.39 pg/ml vs. 9.74 ± 1.49 pg/ml) decreased significantly (P<0.05). Conclusions The Xiaoyaosan had a therapeutic effect on immune dysfunction and increases the expression of serum dopamine in depressive rats, which may be one of the mechanisms of its anti-depression.

Objective: To investigate the association between consumption of cruciferous vegetables (CV), level of urinary isothiocyanates (ITC) and the risk of lung cancer among man in urban Shanghai. Methods: A nested case-control study was conducted within the Shanghai Men's Health Study. Using incidence density sampling with a 2∶1 control to case selection ratio, 885 controls were selected to match 443 lung cancer cases diagnosed prior December 31, 2010. A food-frequency questionnaire was administered to estimate CV consumption. The high performance liquid chromatography method was applied to measure urinary ITC level. The CV intake and urinary ITC level were divided into quartiles according to distribution of control group. The lowest quartile was as a reference group. Conditional logistic regression model was used to analyze the relationship between CV intake, urinary ITC level and the risk of lung cancer. Results: The cruciferous vegetables intake median (P₂₅, P₇₅) in cases and controls were 80.05 (46.89, 129.04) and 97.68 (55.25, 151.72) g/d (Z=-3.93, P<0.001). The urinary ITC level were 1.256 (0.474, 3.836) and 1.244 (0.484, 3.004) μmol/g Cr (Z=-0.39, P=0.697). After adjusting for potential confounding factors such as age, education level, smoking and alcohol consumption, for urinary ITC level, the OR(95%CI) for the highest quartile(≥3.004 μmol/g Cr) was 1.25 (0.87-1.80) compared with the lowest quartile(<0.484 μmol/g). For CV intake, the OR(95%CI) for the highest quartile(≥151.71 g/d) was 0.66 (0.43-1.02) compared with the lowest quartile(<55.25 g/d). Conclusion No association was found between the CV intake, urinary ITC level and lung cancer risk in men.
