Objective To study the therapeutic effect of the type Ⅰ tympanoplasty by the continuous irriga-ting endoscopic ear surgery mode.Methods A total of 50 patients with chronic suppurative otitis media,who pre-pared for the type Ⅰ tympanoplasty in our department,were divided into the traditional operation mode group(20 cases)and the continuous irrigating mode group(30 cases).All patients underwent underlay myringoplasty with tragus cartilage and perichondria limplant.The operation time and postoperative outcome of the two groups were compared and analyzed.Results The mean operation time of the traditional group and the irrigating operation group was 66.10±2.43 minutes and 46.81±5.12 minutes respectively,and there was statistical difference between the two groups(P＜0.05).The tympanic membrane healing rate of the traditional group and the irrigating operation group was 100.00％and 96.67％respectively,and there was no statistical difference between the two groups(P＞0.05).The mean air conduction threshold and the value of air-bone gap were significantly reduced at 2 months after operation compared with that before operation(P＜0.05).There was no significant difference between the two groups in the average pre and post-operative air-bone gaps(P＞0.05).The incidence rates of postoperative compli-cations were 10.00％and 3.33％,respectively,with no statistical significance(P＞0.05).Conclusion The contin-uous irrigating endoscopic ear surgery mode is safe and effective.Under the premise of ensuring clinical efficacy,the operation time is shortened,and it is worth popularizing in middle ear surgery.

Objective To establish a stable rat model of non-obese polycystic ovary syndrome(PCOS)with clinical characteristics.Methods Dehydroepiandrosterone(DHEA)was used to establish a PCOS rat model by subcutaneous injection.Three-week-old female SD rats were divided into a normal group,6 mg/kg DHEA model group,and 60 mg/kg DHEA model group.The model groups were subcutaneously injected with the corresponding dose of DHEA daily,while the normal group was subcutaneously injected with glycerol daily for 21 consecutive days.The model was evaluated with ovarian histopathology as the gold standard to determine the optimal dosage of DHEA to induce a PCOS rat model.On this basis,the optimal DHEA modeling dose was selected,and stop and continue modeling groups were set up to observe the model for 28 days and evaluate its maintenance.The stop modeling group was no longer given DHEA,and the continued modeling group was subcutaneously injected with 60 mg/kg DHEA every 48 h.The evaluation indicators included body mass,estrous cycle,fasting blood glucose,serum insulin,histopathologic morphology of the ovaries,and serum sex hormone levels.Results(1)Compared with the normal group,the 6 mg/kg and 60 mg/kg DHEA model groups showed no significant difference in body mass,and their estrous cycles were irregular.There were more cystically dilated large follicles in the ovaries;fewer mature follicles;reduced layers of granulosa cells,which were arranged in a sparse and disorganized manner;and fewer lutea in the 6 mg/kg and 60 mg/kg DHEA model groups than the normal group.Furthermore,serum T and E2 levels were significantly higher in the 60 mg/kg DHEA model group(P＜0.05)than the normal group.(2)The stop modeling group(A2 group)resumed regular estrous cycles after 2 weeks,various growth follicles and corpora lutea were observed in the ovarian tissues,the number of cystic follicles was reduced,the number of granulosa cell layers increased,mature follicles were visible,oocyte morphology was locally intact,and the levels of E2 and AMH were reduced compared with the normal group(A1 group)(P＜0.05).(3)The continue model group(B2 group)was in the late stage of estrous cycle for a long period,and there were more large follicles with cystic dilatation,fewer mature follicles,fewer layers of granulosa cells with a sparse and disordered arrangement,and significantly fewer corpus lutea in the ovaries compared with the normal group(B1 group).The levels of serum LH,LH/FSH,and T were elevated(P＜0.05).Conclusions Subcutaneous injection of 60 mg/kg DHEA for 21 consecutive days can be used to successfully construct a non-obese PCOS rat model that possesses clinical characteristics.Subcutaneous injection of 60 mg/kg DHEA every 48 hours maintains the stability of the model.

Abstract OBJECTIVE To explore the material basis and mechanism of Crataegi Fructus in improving metabolic hypertension(MH) by using network pharmacology and molecular docking technique.METHODS The components of Crataegi Fructus were collected by HERB, ETCM database and literature survey; screening all ingredients of Crataegi Fructus to improve MH targets through databases such as SwissTargetPrediction and GeneCards; build "active ingredient-target-disease" network of Crataegi Fructus with Cytoscape software; DAVID was used to analyze GO enrichment and KEGG pathway. The core components and core targets were verified by molecular docking with Autodock software. RESULTS The total of 89 active components were screened from Crataegi Fructus and acted on 84 targets. Among them, the core active components of Crataegi Fructus to improve MH were maslinic acid, fomefficinic acid B, linolenic acid, linoleic acid, methyl-n-nonylketone, apigenin, ursolic acid, etc. The core targets were CYP19A1, PPARA, ESR1, PTGS2, PPARG, NR3C1, MMP9, TNF, etc. The mechanism of action mainly involved multiple signaling pathways such as inflammation, glycolipid metabolism, and vascular endothelial function. Molecular docking showed that the core active ingredients of Crataegi Fructus had high affinity with core targets. CONCLUSION Crataegi Fructus may regulate multiple signaling pathways such as TNF, IL-17, AGE-RAGE, HIF-1, cGMP-PKG through multi-component regulation, thereby inhibiting inflammatory response, improving glucose and lipid metabolism abnormalities, and improving vascular endothelial function, so as to comprehensively exert the role of improving MH in various aspects.

Objective: To dynamically observe the progression of chronic gastritis to gastric cancer (GC) in disease-traditional Chinese medicine (TCM) pattern rats to provide data for understanding the disease pro-gression and effective approaches for drug screening and mechanism exploration.Methods: Wistar rats were randomly divided into control (n=96, half female and half male) and model (n = 336, half female and half male) groups. Model rats received free access to N-methyl-N′-nitro-N-nitrosoguanidine (120μg/mL), sodium deoxycholate (20 mmol/L), and alcohol (45％), and were subjected to intermittent fasting. Mortality rate, body weight, water consumption, food intake, gastric pathology, blood content analysis, and liver and kidney function of model rats were dynamically monitored over 30 weeks. In the 30th week, pattern characteristics were assessed. Gastric pathology and pattern charac-teristics were observed for an additional 8 weeks to evaluate stability. Results: The overall mortality of the model group was 34.82％(33.10％for females and 36.55％for males) at 30 weeks post-intervention. Inflammatory cell infiltration, glandular atrophy, atypical hyperplasia, and GC manifested successively in the gastric mucosa of rats. In model rats, N-methyl-N′-nitro-N-nitro-soguanidine intake was lower in males than in females, whereas pathological changes in the gastric mucosa occurred earlier in females than in males. Notably, gastric mucosal lesions were more severe in males than in females. Our modeling methods maintained stable gastric mucosal lesions for at least 8 weeks after final intervention. The pattern characteristics observed in model rats at the 30th and 38th week were consistent with those of spleen deficiency, blood stasis, and yin deficiency pattern. Blood content and indexes of liver and kidney function in the model group were normal. Conclusion: Our findings provide evidence for the pathological stages underscoring the progression of chronic gastritis to GC in disease-TCM pattern rats, which may facilitate development of relevant pharmacotherapies.

Objective:To analyze the gene mutation types and haematological characteristics of αβ compound thalassemia, non-delectable α-thalassemia and Hemoglobin H Disease (HbH disease) in Foshan.Methods:Using the method of retrospective analysis, we selected the population who had been tested for thalassemia gene in Foshan Second People's Hospital Affiliated to Southern Medical University from January 2011 to November 2019. Sysmex XT-5000 automatic hematology analyzer was used for routine blood analysis. α-, β- thalassemia genes were detected by PCR + diversion hybridization method.Results:A total of 4 563 people were tested, of which 1 829 were diagnosed as thalassaemia through genetic diagnosis. αβ compound thalassaemia was detected in 81 cases with a positive rate of 1.8%; non-delectable α-thalassemia was detected in 18 cases with a positive rate of 0.4%; HbH disease was detected in 23 cases with a positive rate of 0.5%. The most common genotypes of αβ compound thalassemia were -- SEA/αα\β41-42/βN (17.3%, 14/81), -α 3.7/αα\β41-42/βN (14.8%, 12/81), -- SEA/αα\β654/βN (11.1%, 9/81). The main manifestations of hematology were normal to mild anemia (93.8%, 76/81). Only β-thalassemia with double heterozygotes and α-thalassemia showed severe anemia. αα CS/αα\βN/βN genotypes were common in the local non delectable α-thalassemia (50.0%, 9/18), and the non delectable α-thalassemia was characterized by non-positive phenotype or typical small-cell hypochromatosis in hematology. The genotypes of local HbH patients were -α 3.7/-- SEA\βN/βN (65.2%, 15/23), and simple HbH manifested as moderate anemia (87.0%, 20/23). Patients with HbH disease and β-thalassemia had normal or mild anemia (13.0%, 3/23). Conclusions:The genotypes of αβ compound thalassemia in Foshan area are diverse and complex, and hematology mainly manifests as mild anemia or normal. Non-delectable α-thalassaemia is common in the genotype of αα CS/αα\βN/βN, and clinical manifestations are asymptomatic gene carriers. The genotype of local HbH patients is mainly -α 3.7/-- SEA\βN/βN, and the hematology mainly shows moderate anemia.

Methods 89 patients with acute brain injury within 24 hours after the injury were divided into severe group(n =47)and mild group(n = 42)according to Glasgow Coma Scale(GCS),and 35 normal healthy adults were selected as control group.In 24 hours and 72 hours after the brain injury,all patients were examined with echocardiography to observe cardiac structure,Doppler blood flow velocity and cardiac function,and in the same time the plasma NPY were determined by radioimmunoassay.Then the results were compared with controls. Results The parameters of cardiac function such as EF、 SV.AV、CO、CI had statistical change in 24 hours and 72hours after the brain injury between severe ABI group and mild ABI group,and it also had statistical change between severe ABI group and control group(all P <0.05),but no statistical change between mild ABI group and control group(all P ＜0.05).The level of plasma NPY in ABI patients was significantly higher than that before injury,there was statistically different change between severe ABI group and mild ABI group,and it also had statistical change between severe ABI group and control group(all P＜0.05).The parameters of cardiac function was negatively correlated with the rise of plasma NPY by pearson correlation analysis(EF:r =- 0.79,P <0.01; SV:r =- 0.71,P <0.01;AV:r=-0.67,P ＜0.01 ;E/A:r =-0.63,all P ＜0.01)and(CO:r =- 0.32,P ＜0.05;CI:r =-0.35,all P ＜0.05). Conclusion The parameters of cardiac function were significantly decreased in the patients with acute brain injury,and it was closely related with the level of plasma NPY.

Objective To explore the molecular mechanism of the formulae for calming the liver and suppressing YANG in migraine rat model with syndrome of hyperactivity of the liver-YANG.Methods A rat model of migraine with hyperactivity of liver-YANG was established through electrical trigeminal ganglion stimulation and syndrome of oral administration of Fuzi decoction. The total proteins of the lymphocyte in the rats were separated by immobilized pH gradient-based 2-dimensional gel electrophoresis(2-DE), and the 2-DE image was analyzed by PDQuest 7.0 software. Matrix-assisted laser desorption/ionzation-time of flight mass spectrometry (MALDI-TOF-MS) and the SWISS-PORT and MSDB database were used to identify differential proteins.Results The formulae for calming the liver and suppressing YANG could also improve headache. Well-resolution and reproducible 2-DE patterns of rat lymphocyte from normal, model, and therapy tissues were obtained. Eleven of the total 13 differential protein spots were successfully identified by MALDI-TOF-MS. These proteins were alcohol dehydrogenase 3(ADH3), glycogen phosphorylase, ATP synthase D chain, annexin-3, ubiquitin, neutrophil defensin 4 precursor, melanoma-associated antigen E2, heat shock protein-27, annexin-A1, peroxirdoxin-Ⅱ, MU class glutathione S-transferase (Fragment)(GSH). Conclusion Differences occur in the expression of lymphocyte proteins in migraine rats with syndrome of hyperactivity of liver-YANG after treatment with the formulae for calming the liver and suppressing YANG, and the 11 identified protein spots may be associated with its mechanism.
