OBJECTIVE: To observe the clinical efficacy and safety of automatic pressure-controlled pressure cupping in patients with lumbar disc herniation, and compare it with traditional cupping. METHODS: A total of 100 patients diagnosed with lumbar disc herniation from January 2022 to August 2024 were selected and divided into two groups:the automatic pressure-controlled pressure cupping group (controlled pressure cupping group) and the traditional cupping group (control group), 50 cases in each group. In the controlled pressure cupping group, there were 18 males and 32 females, with an age of (51.98±12.69) years;in the control group, there were 16 males and 34 females, with an age of (51.32±12.05) years. The visual analogue scale(VAS), comfort score, and lumbar range of motion were observed before treatment and after the 1st, 3rd, and 7th treatments to evaluate the efficacy and safety. RESULTS: All patients completed the treatment intervention, with complete follow-up data collected. No adverse reactions or complications occurred during treatment and follow-up. After the 3rd treatment, the VAS score of the controlled pressure cupping group was (2.38±0.49), which was lower than that of the control group (2.94±0.68), with a statistically significant difference (P<0.001). In the controlled pressure cupping group, the VAS scores after the 1st, 3rd, and 7th treatments were significantly better than those before treatment (P=0.026);in the control group, the VAS scores after the 3rd and 7th treatments were better than those before treatment, but the difference was not statistically significant(P=0.182). Repeated-measures analysis of variance (ANOVA) on VAS scores at different time points in both groups showed that there were statistically significant differences in inter-group, time, and interaction effects (P<0.05). After the 1st treatment, in the controlled pressure cupping group, 0 patients felt comfortable, 42 patients (84%) felt mild discomfort, and 8 patients (16%) felt moderate discomfort;in the control group, 0 patients felt comfortable, 28 patients (56%) felt mild discomfort, and 22 patients(44%) felt moderate discomfort;the difference between the two groups was statistically significant(P=0.005). After the 3rd treatment, in the controlled pressure cupping group, 30 patients(60%) felt comfortable, 20 patients (40%) felt mild discomfort, and 0 patients felt moderate discomfort; in the control group, 9 patients (18%) felt comfortable, 41 patients (82%) felt mild discomfort, and 0 patients felt moderate discomfort;the difference between the two groups was statistically significant(P<0.001). There was no statistically significant difference in comfort between the two groups after the 7th treatment(P>0.001). There was no statistically significant difference in lumbar range of motion between the two groups before and after treatment(P>0.05);compared with before treatment, the lumbar range of motion of both groups after treatment was significantly improved, with statistically significant differences (P<0.001). CONCLUSION Automatic pressure-controlled pressure cupping can effectively relieve symptoms in patients with lumbar disc herniation, with excellent safety.

The "student-centered" flipped classroom teaching model can improve students' academic achievement, improve cognition, and cultivate innovation ability. However, it has obvious deficiencies in the integrity and systematization of knowledge as well as education. The traditional teaching concept based on " teacher-centered" has the unique advantages of systematization of knowledge learning and education. Therefore, we integrated the merits of these two different teaching models and introduced the semi-flipped classroom teaching model into the Biochemistry teaching of 2020 stomatology, pharmacy and preventive medicine majors in Cheeloo Medical College, Shandong University, compared with the traditional teaching of 2019 same majors. The data on the improvement of students ' academic achievement and self-cognition were analyzed. The results showed that the students' achievements of the semi-flipped classroom teaching model were better than those of the traditional teaching (P<0. 01). The students' self-cognitions were significantly improved after the implementation of semi-flipped classroom teaching (P<0. 01 or P<0. 05). This study provides a reference for the related teaching and research work in medical colleges.

【Objective】 To investigate the mechanism of atorvastatin improving ventricular remodeling in rats with myocardial infarction. 【Methods】 Ligation of left anterior descending coronary artery was performed to establish rat model of myocardial infarction. Thirty rats were divided into sham group(n=10), myocardial infarction group(n=10) and atorvastatin group(n=10). Echocardiography was used to examine cardiac function and left ventricular mass index(LVMI) was calculated. The content of arginine vasopressin(AVP) in left ventricular non-infarct area and serum was measured by ELISA. Masson staining was used to observed interstitial fibrosis of myocardium. Immunohistochemistry was used to measure the expression of type Ⅰ collagen. The protein expression of transforming growth factor-β1(TGF-β1) was detected by western blot. 【Results】 After 5 weeks, the number of rats in sham group, myocardial infarction group and atorvastatin group was 10, 9 and 10, respectively. Compared with sham group, LVEF was significantly decreased and, LVMI, interstitial fibrosis, the content of AVP, the expression of type Ⅰ collagen and TGF-β1 in the left ventricular non-infarct area were significantly increased in myocardial infarction group and atorvastatin group(P<0.05). Atorvastatin significantly increased LVEF and decreased interstitial fibrosis, the content of AVP, the expression of type Ⅰ collagen and TGF-β1 in the left ventricular non-infarct area(P<0.05) . 【Conclusion】 Atorvastatin could ameliorate ventricular remodeling in rats with myocardial infarction, which might be associated with inhibiting the expression of AVP and TGF-β1.

OBJECTIVETo investigate the mechanism of Panax notoginseng saponins (PNS), an effective component extracted from Panax notoginseng, on atherosclerotic plaque angiogenesis in atherosclerosis-prone apolipoprotein E-knockout (ApoE-KO) mice fed with high-fat, high-cholesterol diet.

METHODSTwenty ApoE-KO mice were divided into two groups, the model group and the PNS group. Ten normal C57BL/6J mice were used as a control group. PNS (60 mg/kg) was orally administered daily for 12 weeks in the PNS group. The ratio of plaque area to vessel area was examined by histological staining. The tissue sample of aortic root was used to detect the CD34 and vascular endothelial growth factor (VEGF) expression areas by immunohistochemistry. The expression of VEGF and nicotinamide adenine dinucleotide phosphate oxidase subunit 4 (NOX4) were measured by reverse transcription polymerase chain reaction and Western blotting respectively.

RESULTSAfter treatment with PNS, the plaque areas were decreased (P<0.05). CD34 expressing areas and VEGF expression areas in plaques were significantly decreased (P<0.05). Meanwhile, VEGF and NOX4 mRNA expression were decreased after treatment with PNS. VEGF and NOX4 protein expression were also decreased by about 72% and 63%, respectively (P<0.01).

CONCLUSIONPNS, which decreases VEGF and NOX4 expression, could alleviate plaque angiogenesis and attenuate atherosclerosis.

OBJECTIVETo explore the effect of hemoperfusion (HP) on tylenol poisoned patients.

METHODSUrgently established the blood access by transfemoral catheterization of femoral vein, we used charcoal hemoperfusion by blood pump and dynamically monitored the plasma concentration of tylenol active ingredients for the 2 patients and the content of tylenol active ingredients in the charcoal was determined.

RESULTSPlasma concentration of tylenol active ingredients of the 2 patients was declined gradually during and after the HP management. The acetaminophen serum concentration of the case 1 was declined from the 13.4 µg/L at the start of HP to the 5.81 µg/L at the end of HP; and the case 2 was declined from 51.1 µg/L to 22.3 µg/L. The adsorption amount of acetaminophen in the blood perfusion device are respectively 119 542 µg of case 1 and 33 2154 µg of case 2.

CONCLUSIONEarly hemoperfusion should be carried out for acute tylenol poisoning patients if there were indications, hemoperfusion can clear the tylenol active ingredients and this is an effective measure to eliminate tylenol active ingredients.
