OBJECTIVE: To observe the clinical efficacy of Xujiang Xie's bloodletting therapy combined with Qingyan Lige decoction on acute pharyngitis with lung-stomach heat accumulation. METHODS: A total of 88 patients with acute pharyngitis of lung-stomach heat accumulation were randomly divided into an observation group (44 cases, 4 cases dropped out) and a control group (44 cases, 4 cases dropped out). The control group was treated with oral Qingyan Lige decoction, 150 mL each time, twice a day for 6 continuous days. On the basis of the treatment in the control group, Xujiang Xie's bloodletting therapy was applied at bilateral Shaoshang (LU11), Shangyang (LI1), and Erjian (EX-HN6) in the observation group, 0.1-0.5 mL of bloodletting per site, once every other day for 3 times in total. The TCM symptom and sign score, complete blood count (white blood cell [WBC] count, neutrophilic granulocyte percentage [NE%]), inflammation indexes (serum levels of C-reactive protein[CRP], interleukin[IL]-1β, IL-6, tumor necrosis factor [TNF]-α) and immune indexes (？？, ？？, ？？) of the two groups were observed before treatment and after 6 days of treatment, and the clinical efficacy was evaluated. RESULTS: After 6 days of treatment, the sore throat scores, redness and swelling scores of pharyngeal mucosa and uvula, pharyngeal dry and burning scores, hyperemia scores of posterior pharyngeal lymphoid follicles, chill and fever scores, total scores of TCM symptom and sign, WBC count, NE%, CRP, IL-1β, IL-6, TNF-α and ？？ in both groups were decreased compared with those before treatment (P<0.05), the above indexes in the observation group were lower than those in the control group (P<0.01, P<0.05, P<0.001). After 6 days of treatment, the levels of ？？ and ？？ in both groups were increased compared with those before treatment (P<0.05), and the above indexes in the observation group were higher than those in the control group (P<0.001). The total effective rate of the observation group was 95.0% (38/40), which was higher than 90.0% (36/40) in the control group (P<0.001). CONCLUSION Xujiang Xie's bloodletting therapy combined with Qingyan Lige decoction could improve the symptoms in patients with acute pharyngitis of lung-stomach heat accumulation, inhibit inflammatory response and improve immune function.

Non-alcoholic fatty liver disease (NAFLD) is a metabolic disease characterized by abnormal deposition of lipid in hepatocytes. If not intervened in time, NAFLD may develop into liver fibrosis or liver cancer, and ultimately threatening life. NAFLD has complicated etiology and pathogenesis, and there are no effective therapeutic means and specific drugs. Currently, insulin sensitizers, lipid-lowering agents and hepatoprotective agents are often used for clinical intervention, but these drugs have obvious side effects, and their effectiveness and safety need to be further confirmed. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) plays a central role in maintaining energy homeostasis. Activated AMPK can enhance lipid degradation, alleviate insulin resistance (IR), suppress oxidative stress and inflammatory response, and regulate autophagy, thereby alleviating NAFLD. Natural herbal medicines have received extensive attention recently because of their regulatory effects on AMPK and low side effects. In this article, we reviewed the biologically active natural herbal medicines (such as natural herbal medicine formulas, extracts, polysaccharides, and monomers) that reported in recent years to treat NAFLD via regulating AMPK, which can serve as a foundation for subsequent development of candidate drugs for NAFLD.

Objective:To explore the role of prognostic nutritional index (PNI) and pleural thickness in the prognostic evaluation of patients with epithelial malignant pleural mesothelioma (MPM) .Methods:In April 2022, a retrospective analysis was conducted on the data and laboratory data of 41 patients with epithelial MPM admitted to the cardiothoracic surgery department of Chuxiong Yi Autonomous Prefecture People's Hospital from January 2018 to May 2021. Univariate and multivariate analysis were used to evaluate the relationships between total survival time, clinical characteristics, PNI and pleural thickness in patients.Results:The 41 patients were mostly male (26 cases, 63.4%) , with a median age of 55 years old. The main clinical manifestations were chest pain (53.7%) , bloody pleural effusion (75.6%) , and chest pain combined with bloody pleural effusion (36.6%) . The median survival time of patients with different TNM stage, efficacy after 4 cycles of chemotherapy, PNI, maximum pleural thickness after chemotherapy (post max) , sum of post max in 3 zones after chemotherapy (post sum) were statistically different (χ 2=3.89, 14.51, 15.33, 4.33, 12.05, P<0.05) . Compared with patients with high PNI and post sum<32.26 mm, MPM patients with low PNI and post sum≥32.26 mm have higher risk of death, and the differences were statistically significant ( HR=1.52, 95% CI: 1.75-11.93, P=0.002; HR=1.70, 95% CI: 1.84-16.23, P=0.002) . Conclusion:PNI and post sum can be used to predict the prognosis of patients with epithelial MPM.

Objective To apply PDCA(plan,do,check and action)cycle to optimize management and shorten the turnaround time(TAT)of five sex hormone tests for improving clinical efficiency and patient satisfaction.Methods A PDCA management team was established to retrospectively analyze the current status of sex hormone TAT in 2021.In 2022,PDCA tools were utilized,including fishbone diagrams for cause analysis,Pareto charts for root cause identification,formulation and implementation of corresponding im-provement measures and monitoring of TAT changes before and after PDCA.Results Through the corrective measures,such as staff personnel training,increasing testing equipment,optimization process and other improvement measures,the median TAT of sex hor-mone samples in 2022(post-PDCA improvement)was 54 minutes which was significantly lower than 61 minutes in 2021(pre-PDCA)(P＜0.05).Conclusion PDCA cycle management effectively shortened the TAT of sex hormone samples,enhanced clinical diagnostic efficiency and patient experience,improved doctor-patient relationships,while also elevated the quality management standards of labo-ratories.

Objective To evaluate the maturity and metabolic status of heterotopic ossification(HO)by single-photon emission computed tomography(SPECT)/CT fusion bone imaging.Methods The clinical and SPECT/CT fusion bone imaging data of 57 patients with HO confirmed by pathology or follow-up were analyzed retrospectively.HO was graded by CT,and the characteristics of radioactive concentration of HO were analyzed.Results Of 57 cases,single lesion in 52 cases,and multiple lesions in 5 cases,with a total of 63 lesions,mostly located in the hip joint(55.6%,35/63)and thigh(19.0%,12/63).There were 41 lesions in the middle stage and 22 lesions in the late stage.In the visual evaluation of SPECT/CT fusion bone imaging,the middle stage lesions were mostly clumps or flakes,with moderate or high radioactive concentration(75.6%,31/41),furthermore,the concentration range was larger than or equal to the total or limited range of CT ossification(21/41,50.1%),with high concentration mainly located in the mixed areas of ossification density.The concentration of the late stage lesions was mostly non-radioactive(72.7%,16/22).Conclusion SPECT/CT fusion bone imaging can show the range,degree and maturity of HO radioactive concentration,and can accurately locate the area with osteoblastic activity,which provides scientific basis for the selection of surgical timing.

Purpose To explore the CT features of solid components between benign and malignant mixed ground-glass nodules(mGGO),and between minimally invasive adenocarcinoma(MIA)and invasive adenocarcinoma(IAC),and to improve the accuracy of preoperative diagnosis of mGGO.Materials and Methods The clinical and imaging data of 313 patients with mGGO admitted to the First Affiliated Hospital of Chongqing Medical University from January 2016 to July 2022 were retrospectively analyzed,and all patients were divided into benign group(95 cases)and malignant group(218 cases)according to follow-up or pathological results.All patients in malignant group were further divided into MIA(118 cases)and IAC(100 cases)groups.Logistic regression analysis models were established using the statistically significant CT features above,and the area under the curve(AUC)was calculated to evaluate the effectiveness of the model.Results ① Comparison of clinical characteristics between benign and malignant groups:malignant mGGO were more common in older people,females and nonsmokers,without smoking history,and the differences between two groups were significantly different(Z=-3.776,χ2=13.587,19.257;all P<0.001).②Comparison of CT features between benign and malignant groups:benign group existed a higher proportion of single solid component(84.21%vs.55.50%),while malignant group existed a higher proportion of multiple solid components(44.50%vs.15.79%),and the difference between two groups was significantly different(χ2=23.728,P<0.001).As for patients with single solid component,the solid components in malignant group were more likely to be irregular,mostly with eccentric distribution,and the proportion of solid components connected with blood vessels and pleura were higher than the benign group,the differences between two groups were significant(χ2=23.785,5.025,7.264;all P<0.05).Meanwhile,the benign group also had higher CT value[-153.00(-254.00,-80.50)Hu vs.-265.00(-363.25,-122.00)Hu],while lower relative CT value(0.30±0.16 vs.0.41±0.22),the differences between two groups were significant(all P<0.001).Logistic regression analysis:irregular morphology of the solid component(OR=0.236,P<0.001)and higher CT value(OR=1.009,P<0.05)were independent predictors of malignant mGGO.Receiver operator characteristic(ROC)curve analysis showed that the AUC was 0.772,and its accuracy,sensitivity and specificity was 70.65%,74.40%and 65.00%,respectively.③Comparison of CT features between MIA and IAC groups:MIA group existed a higher proportion of single solid component(74.58%vs.33.00%),while IAC group existed a higher proportion of multiple solid components(67.00%vs.25.42%),and the difference between two groups was significantly different(χ2=37.885,P<0.001).As for patients with single solid component,the solid components in IAC group were more likely to be irregular,it also had higher area,area proportion,and CT value,while lower relative CT value than the MIA group,the differences between two groups were significant(χ2=7.563,Z=-4.388,-3.923,-3.996;all P<0.05).Logistic regression analysis:eccentric distribution of the solid component(OR=0.083,P<0.05)and large area(OR=1.063,P<0.05)were independent predictors of IAC.ROC curve analysis showed that the AUC was 0.865,and its accuracy,sensitivity and specificity was 83.47%,87.90%and 68.20%,respectively.Conclusion The solid components between benign and malignant nodules as well as between MIA and IAC show different CT features.Based on these different features,it's helpful to improve the preoperative diagnostic accuracy of mGGO and guide the clinical treatment plans.

Objective:To observe and compare the clinical characteristics between post-chronic pancreatitis diabetes mellitus(PPDM-C)patients and type 2 diabetes mellitus(T2DM).Methods:Data of 142 cases of CP patients confirmed in Shanghai Pudong New Area Gongli Hospital from January 2018 to December 2021 were collected, all the patients were divided into CP group without diabetes mellitus ( n=60) and PPDM-C group with diabetes mellitus ( n=82) based on whether with or without diabetes mellitus. And 82 cases T2DM without CP (T2DM group, n=82) hospitalized simultaneously were collected as control group. The age, sex, body mass index, onset characteristics, laboratory examination indicators at admission (fasting blood glucose, glycosylated hemoglobin, blood creatinine, and alanine transaminase), imaging characteristics of the pancreas (pancreatic atrophy, multiple calcifications of the pancreas, pancreatic duct stones, pancreatic duct dilation, and pancreatic duct obstruction), and treatments and efficacy of diabetes were recorded. Results:Compared with T2DM group, PPDM-C group had lower body mass index (22.2 kg/m 2vs 24.6 kg/m 2), and glycosylated hemoglobin levels (7.34% vs 9.20%) (all P values <0.001), higher alanine transaminase levels (33.00 U/L vs 18.65 U/L, P =0.021). And they had more upper abdominal pain, nausea, vomiting, weight loss and diarrhea symptoms. In addition, they had less use of combination of insulin and hypoglycemic drugs to control blood glucose. And compared with CP group, PPDM-C group had higher body mass index (22.06 kg/m 2vs 21.18 kg/m 2), higher glycosylated hemoglobin levels (7.34% vs 5.70%), higher fasting blood-glucose levels (7.91 mmol/l vs 5.31 mmol/l), higher alanine transaminase levels (33.00 U/L vs 26.50U/L), and their differences were statistically significant (all P values <0.05). And they had higher incidence of pancreatic atrophy, multiple calcifications in the pancreatic duct and pancreatic duct obstruction (all P values <0.05). Conclusions:PPDM-C patients are more likely to experience digestive system symptoms such as abdominal pain than T2DM patients, while their pancreatic malfunction is more likely to occur compared to CP patients. More attentions to PPDM-C associated clinical manifestations, biochemical and imaging changes could identify patients at potential risk for early diagnosis and treatment earlier.

OBJECTIVE To study the effect and potential mechanism of eriodictyol on non-alcoholic fatty liver disease （NAFLD）. METHODS Sixteen C57BL/6J mice were randomly divided into control group， NAFLD model group， and eriodictyol low-dose and high-dose groups （50， 100 mg/kg）， with 4 mice in each group. Except for control group， the other groups were fed with high fat diet to induce NAFLD model. After four weeks of preprocessing， they were given relevant medicine intraperitoneally （0.01 mL/g）， once a day， for 6 consecutive weeks. The body weight and liver weight of mice were measured， and the pathological damage of liver tissue in mice was observed. The levels of aspartate aminotransferase （AST）， alanine aminotransferase（ALT）， and triglycerides （TG） in serum， as well as the protein expressions of nuclear factor-erythroid 2-related factor 2 （Nrf2） and heme oxygenase-1 （HO-1） in liver tissue were determined. In vitro NAFLD model was established by using 0.5 mmol/L oleic acid （OA） in HepG2 cells. Normal control group， NAFLD model group and eriodictyol low-， medium- and high-concentration groups （50， 100， 150 μmol/L） were set up. HepG2 cells in drug groups were treated with eriodictyol for 24 h at the time of modeling. The lipid deposition was observed in cells， and the levels of TG， malondialdehyde （MDA） and reactive oxygen species （ROS） as well as the phosphorylation levels of the mitogen-activated protein kinase （MAPK） signal pathway related proteins [extracellular signal-regulated kinase （ERK）， c- Jun N-terminal kinase （JNK）] and the protein expressions of Nrf2 and HO-1 were all determined. RESULTS In the in vivo experiment， compared with the NAFLD model group， the body weight， liver weight， the serum levels of AST， ALT and TG were all decreased significantly in eriodictyol low- and high-dose groups （except for serum level of AST in eriodictyol low-dose group） （P＜0.01）； liver lipid deposition was reduced significantly and the protein expressions of Nrf2 and HO-1 in liver tissues were further up-regulated （P＜0.01）. In the in vitro experiment， compared with the NAFLD model group， the lipid deposition in hepatocytes was reduced in eriodictyol low-， medium- and high-concentration groups （P＜0.01）， and the levels of ROS， MDA and TG were down-regulated （P＜0.05 or P＜0.01）； the phosphorylation levels of ERK and JNK were significantly down-regulated （P＜0.01）， while the protein expressions of Nrf2 and HO-1 were up-regulated significantly （P＜0.01）. CONCLUSIONS Eriodictyol can inhibit MAPK signaling pathway and activate Nrf2/HO-1 signaling pathway to alleviate NAFLD.
