OBJECTIVE: To observe the pulmonary vascular remodeling in rats with pulmonary hypertension induced by hypoxia and hypercapnia, and to explore the role of endoplasmic reticulum stress in pulmonary hypertension. METHODS: Forty SD rats were random-ly divided into four groups:normoxic control group (N), hypoxia hypercapnia group (HH), ERS inhibitor 4-phenylbutyric acid group (4-PBA), endoplasmic reticulum stress (ERS) pathway agonist tunicamycin group (TM), ten rats in each group.The mean pulmona-ry artery pressure (mPAP), mean carotid artery pressure (mCAP) and right ventricular hypertrophy index of rats in each group were measured.Pulmonary artery smooth muscle cells were identified by immunofluorescence α-smooth muscle actin (α-SMA).Morphologi-cal changes of lung tissue and pulmonary artery were observed by electron microscope.The apoptotic index of pulmonary artery smooth muscle cells in each group was detected by TUNEL.Reverse transcription polymerase chain reaction (RT-PCR) and Western blot were used to detect the expression of glucose-regulated protein (GRP78), C/EBP homologous protein (CHOP), c-Jun N-terminal kinase (JNK) and cysteinyl aspartate specific proteinase-12 (caspase-12) mRNA and protein in each group. RESULTS: ①Compared with the N group, the mPAP, the ratio of right ventricle weight to left ventricle plus ventricular septum weight[RV/(LV+S)]and the ratio of pulmonary artery wall area to total tube area (WA/TA) were increased (<0.01), and the ratio of pulmonary artery luminal area to total tube area (LA/TA) were decreased (<0.01), pulmonary artery smooth muscle cell apoptosis index were decreased (<0.05 or <0.01) in HH group, 4-PBA group and TM group.ERS related protein and mRNA expressions were increased, the differences were statistically significant.②Compared with the HH group, the mPAP, [RV/(LV+S)]and WA/TA of 4-PBA group were decreased ( <0.01), LA/TA and pulmonary artery smooth muscle cell apoptosis index were increased (<0.01, <0.05).The expressions of ERS related protein and mRNA were all decreased (<0.05 or <0.01).③Compared with the HH group, the mPAP, [RV/(LV+S)]and WA/TA of TM group were increased (<0.05 or <0.01), pulmonary artery middle layer thickened, LA/TA and pulmonary artery smooth muscle cell apoptotic index were decreased (<0.01).ERS related protein and mRNA expressions were increased with statistical significance except GRP78 protein. CONCLUSIONS Pulmonary vascular remodeling in rats with pulmonary hypertension induced by hypoxia and hypercapnia may be related to the excessive proliferation of pulmonary artery smooth muscle cells and too little apopto-sis;ERS related factors (JNK, caspase-12 and CHOP) are involved in the regulation of pulmonary hypertension induced by hypoxia hypercapnia.

OBJECTIVETo investigate the effect of exogenous recombinant human basic fibroblast growth factor (rhbFGF) on the healing of muscles in rats after deep tissue injury of pressure ulcers.

METHODSForty-eight SD rats were randomly divided into normal control group, injury control group, post injury day (PID) 4 group, PID 7 group, PID 14 group, PID 21 group according to the random number table, with 8 rats in each group. The rats in normal control group did not receive any treatment, whereas the rats in the latter 5 groups were established the deep tissue injury of pressure ulcer model on both sides of the gracilis muscle on the hind limb. The rats in injury control group did not receive any treatment after injury, while the rats in the latter 4 groups were given subcutaneous injection of 0.1 mL rhbFGF to the left gracilis in a dosage of 100 µg/mL immediately after injury, and an equal volume of normal saline (NS) was injected to right gracilis, once every other day. The rats in injury control group were sacrificed immediately after injury, and the rats in normal control group were sacrificed at the same time point. The rats in the other 4 groups were sacrificed on PID 4, 7, 14, 21, and the gracilis muscles on both sides were harvested respectively. The morphology of the gracilis muscle was examined after HE staining. The expression of myogenin in the tissues was detected by immunofluorescence method. The levels of muscle structural proteins myosin heavy chain (MyHC), phosphorylated protein kinase B (Akt), and phosphorylated mammalian target of rapamycin (mTOR) were determined by Western blotting. Data were processed with one-way analysis of variance and LSD test.

RESULTS(1) In normal control group, the nuclei of graciles cells were in uniform size, and they were closely arranged with clear structure, and there were no significant infiltration of inflammatory cells. In injury control group, the nuclei of graciles cells showed signs of pyknosis, dissolution, fracture and structural disorder. Swelling of muscle cells, inflammation infiltration, structural disorder and other pathological signs of injury phenomena in graciles of PID 4 group, PID 7 group, PID 14 group, PID 21 group after rhbFGF treatment were milder compared with those after NS treatment. In addition, the numbers of regenerated myocytes in graciles of PID 4 group, PID 7 group, PID 14 group, PID 21 group after rhbFGF treatment were higher than those after NS treatment. (2) The numbers of graciles myogenin positive cells in normal control group and injury control group were respectively 28 ± 17 and 42 ± 28. The numbers of graciles myogenin positive cells in PID 4 group, PID 7 group, PID 14 group after NS treatment were 100 ± 50, 196 ± 87, 460 ± 110 respectively, while the numbers of graciles myogenin positive cells in PID 4 group, PID 7 group, PID 14 group after rhbFGF treatment were 174 ± 34, 717 ± 182, 613 ± 122 respectively, and the numbers of graciles myogenin positive cells after rhbFGF treatment were significantly higher than those after NS treatment in each group(P < 0.05 or P < 0.01). The number of graciles myogenin positive cells in PID 21 group after rhbFGF treatment was 109 ± 34, which was significantly lower than that after NS treatment (218 ± 71, P < 0.05). (3) The expression of MyHC in graciles in normal control group was high, which was decreased in injury control group. Both the expressions of MyHC in graciles in PID 4 group, PID 7 group, PID 14 group, PID 21 group after treatment of NS and rhbFGF showed a trend of gradual elevation, while the expressions of MyHC in graciles after rhbFGF treatment were significantly higher than those after NS treatment (P < 0.05 or P < 0.01). The expression of MyHC in graciles in PID 21 group showed a high level, and it was similar to that of the normal control group (P > 0.05). The expressions of phosphorylated Akt and phosphorylated mTOR in graciles of normal control group were low, and the expression of phosphorylated Akt in graciles increased in injury control group, while the expression of phosphorylated mTOR in graciles decreased in injury control group. The expressions of phosphorylated Akt and phosphorylated mTOR in graciles of PID 4 group, PID 7 group, PID 14 group, PID 21 group after treatment with rhbFGF showed a trend of elevation in the beginning but declined afterwards. The expressions of phosphorylated Akt and phosphorylated mTOR in graciles of PID 4 group after rhbFGF treatment were significantly lower than those after NS treatment (P <0 .05 or P < 0.01). The expressions of phosphorylated Akt and phosphorylated mTOR in graciles of PID 7 group, PID 14 group, PID 21 group after rhbFGF treatment were significantly higher than those after NS treatment (P < 0.05 or P < 0.01).

CONCLUSIONSExogenous rhbFGF may effectively facilitate the healing of muscle structure and accelerate the regeneration of muscles in rats after deep tissue injury of pressure ulcers, and its mechanism may be related to the improvement of the expression of myogenin and enhancement of the expression of protein of muscle growth-related signaling pathways.

Objective: To analyze the etiology and epidemiological characteristics of influenza in Wenzhou from 2009 to 2014, so as to provide the scientific basis for control and prevention of influenza. Methods: Throat swab specimens of influenza like illness (ILI) were collected from national influenza surveillance sentinel hospitals for nucleic acid detection with real-time PCR and virus isolation, culture and sequencing, and the results were analyzed with statistical methods. Results: During the 8 years, a total of 10 577 089 cases from outpatient and emergency department were monitored in sentinel hospitals. There were 337 896 ILI cases with an average ILI treatment rate of 3.19%. A total of 4 046 ILI samples were detected in children, 511 were positive for influenza, the positive rate was 12.63%. Among the detected influenza types, type B had the highest proportion, followed by H3N2. Among the 6 age groups, the number of flu patients was the highest in 0-3 years old group, the positive rate in 10-12 years old group was the highest (35.03%). There were 28 and 45 amino acid sequence mutations of HA fragment in influenza A and B, respectively, which included multiple mutation of 391 and 145 amino acids. The phylogenetic analysis showed that the strains of type B were different in different years, and Yamagata evolved into Y1 and Y2 two branches. Conclusions The prevalence peaks of influenza in children occurred in winter and spring in Wenzhou city, accompanied by small peaks in summer. Three subtypes of serotypes B, H3N2 and A(H1N1) dominated alternatively in Wenzhou during the 8 years. We should focus on strengthening the prevention and control of influenza in preschool children and primary and secondary school students.

ObjectiveTo establish an ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)-internal standard method for the simultaneous determination of 59 antibiotics, including quinolones, sulfonamides, tetracyclines, macrolides and nitroimidazole in bean sprouts. MethodsThe internal standard compounds and 5.0 mL of acetonitrile containing 0.1% formic acid were added into 5.0 g of the sample, and then extracted by ultrasonication. The extracted supernatant was filtered by 0.22 µm membrane and then injected into 1.0 µL of the sample directly. Methanol containing 0.1% formic acid and 2.0 mmol·L^-1 ammonium formate containing 0.1% formic acid were taken as the mobile phases to conduct gradient elution. The separation was achieved on an ACQUITY PREMIER BEH C₁₈ column. The separated analytes were detected by the electrospray ionization (ESI) in multiple reaction monitoring (MRM) mode, and quantified by internal standard method. ResultsThe 59 kinds of antibiotics in bean sprouts had a good linear relationship in the range of 10 μg·kg^-1 to 1 000 μg·kg^-1. The limits of detection (LODs) and the limits of quantification (LOQs) of the method for soybean sprouts ranged from 0.1 μg·kg^-1 to 3.0 μg·kg^-1 and 0.4 μg·kg^-1 to 10.0 μg·kg^-1, respectively. While, the LODs and LOQs of the method for mung bean sprouts ranged from 0.1 μg·kg^-1 to 2.0 μg·kg^-1 and 0.4 μg·kg^-1 to 7.0 μg·kg^-1, respectively. The average recoveries of the 59 kinds of antibiotics at four levels (10、50、200、800 μg·kg^-1) in soybean sprouts were 82.1%‒122.3%, with the relative standard deviations (RSDs) of 1.2%‒15.4% (n=6). However, the average recoveries of the 59 kinds of antibiotics in mung bean sprouts were 87.3%‒119.1%, with the RSDs of 0.9%‒15.0% (n=6). ConclusionThe method is rapid, highly sensitive and accurate, which can be used for rapid screening of quinolones, sulfonamides, tetracyclines, macrolides, and nitroimidazole antibiotics in large quantities of bean sprouts.

A foodborne poisoning incident occurred in a street， Ouhai District， Wenzhou City， Zhejiang Province on May 9， 2023， which was caused by the accidental consumption of medicinal liquor containing aconitum alkaloids. Three individuals drank homemade aconite-containing medicinal liquor and were subsequently poisoned， of which two cases were severe， and one case was mild. All three patients exhibited symptoms such as numbness in the mouth， tongue and limbs， dizziness， fatigue， nausea， vomiting， and blurred vision. Two of them successively entered a state of shock and coma， with an incubation period of approximately 30 minutes. Among seven samples of suspected homemade medicinal liquor， one sample tested positive simultaneously for aconitine， neaconitine， hypaconitine， and benzoylaconitine， with concentrations of 62.3 mg·L^-1， 2.6 mg·L^-1， 17.7 mg·L^-1， and 31.6 mg·L^-1， respectively. Four kinds of aconite alkaloids were detected in all the urine， blood， and vomit samples from the patients， and the most toxic aconitine was detected at levels of 1.5 μg·L^-1， 5.9 μg·L^-1， and 26.2 μg·L^-1， respectively. Based on the field epidemiological investigation， combined with clinical manifestations and laboratory test results， it was determined that this incident was a case of food poisoning caused by the accidental consumption of medicinal liquor containing aconite. Due to timely rescue and proper treatment measures， all poisoned patients have recovered， with no fatalities. It is suggested that relevant authorities should strengthen the regulation of the processing and sale of aconite herbs and promote the awareness of food safety.

OBJECTIVETo observe the effect of curcumin on nitric oxide (NO) in plasma of atherosclerotic rabbits, activity of constitutive nitric oxide synthase (cNOS) and asymmetric dimethylarginine (ADMA), and discuss curcumin's effect against AS and its correlation with ADMA.

METHODThirty-eight male Japanese white rabbits were randomly divided into four groups: the control group (eight rabbits fed with standard diets), the model group (ten rabbits fed with high-fat diets), the low dose curcumin group (ten rabbits fed with high-fat diets and 100 mg . kg-1 d -1 ) and the high dose curcumin group (ten rabbits fed with high-fat diets and 200 mg kg-1 d-1 curcumin). At the end of the 12th week, their plasmas were tested for TC, LDL-C, NO, endothelin (ET) , ADMA and activity of aortic cNOS. Aortic tissues were collected for histological examinations.

RESULTThe three groups fed with high-fat diets showed higher plasma ADMA and ET than the control group (P <0. 01) , but with decrease in plasma NO concentration and arterial cNOS activity (P <0. 01). Compared with the model group (P <0. 05) , the curcumin groups showed lower plasma ADMA and ET (P <0. 05), but higher plasma NO concentration and arterial cNOS activity than the model group (P <0. 01). There was no significant difference between the two curcumin groups.

CONCLUSIONCurcumin may play an important protective role in AS process by reducing plasma ADMA level. [Key words] atherosclerosis; asymmetric dimethylarginine; crucumin; nitric oxide; nitric oxide synthase

In order to investigate the effect of Shouwu Shudi Yin on dopaminegic neurons in MPTP induced Parkinson's disease mouse model and the possible mechamism, the experimental mice were randomly divided into 4 groups: control, Shouwu Shudi Yin, MPTP and the treatment (MPTP+Shouwu Shudi Yin) groups. The number of tyrosine hydroxylase (TH) positive cells in the substantia nigra was measured by immunohistochemistry, and mRNA expression of TH and glutathione peroxidase (GPX) were detected by PCR. The results showed that the number of TH positive cells and mRNA expression of TH were significantly reduced in MPTP group compared with the control (P<0.05), and pretreated with Shouwu Shudi Yin didn't show protective effect. Compared to MPTP group, the mRNA expression of four subtypes of GPX were increased in various degrees in the treatment group pretreated with Shouwu Shudi Yin, although the difference was not statistically significant. These indicated that the preventive medication of Shouwu Shudi Yin don't have protective effect on the mice with Parkinson' s disease induced by MPTP, but it may enhance the antioxidant capacity through increasing the expression of GPX.

ObjectiveTo investigate the status and dietary intake risk of pesticide residues in fruits and vegetables sold in Wenzhou, Zhejiang Province from 2020 to 2023, so as to provide a scientific basis for the regulation and management of pesticide in the future. MethodsIn accordance with the requirements and methods specified in the “National Food Contamination and Hazardous Factor Risk Monitoring Work Manual” and the current corresponding national food inspection standards for various foods, a total of 807 samples of vegetables and fruits from various counties and districts of Wenzhou City were collected for testing and analysis. Eventually, 23 types of pesticides with a detection rate greater than 5% and those exceeding the standard were selected for dietary intake risk assessment. ResultsFrom 2020 to 2023, the overall detection rate of pesticide residues in fruits and vegetables monitored in Wenzhou was 71.62%, with an overall exceedance rate of 5.27%. From the results of the monitoring of pesticide residues in fruits and vegetables, fresh legume vegetables had the highest detection rate of 90.00%. Among the six major categories of pesticides monitored, fungicides in vegetables and fruits had the highest detection rates of 68.18% and 85.03%, respectively. The highest exceedance rate in vegetables was organophosphorus pesticides, accounting for 2.85%, while in fruits, neonicotinoid pesticides had the highest exceedance rate of 3.21%. From the perspective of sampling time, the peak detection rate of pesticide residues in fruits and vegetables in Wenzhou occurred in June and October. The index of food safety (IFS) of the 23 pesticides with a detection rate higher than 5% ranged from 0.000 7 to 0.694 2 based on the 95% monitoring value of pesticide residues, which were all less than 1. Calculated at maximum content, the IFS values of dithiocarbamate (calculated by CS₂), chlorothalonil and propiconazole were all greater than 1, indicating that the maximum detection values of the three pesticides exceeded the acceptable safety risk. The risk level of acute dietary intake of the 23 pesticides ranged from 1.26% to 52.65%. ConclusionThe overall situation of pesticide residues in fruits and vegetables sold in Wenzhou from 2020 to 2023 is favourable, but the exceedance rate of pesticide in some fruits and vegetables is high. Special attention should be paid to the pesticide residues of fungicides, neonicotinoid insecticides and organophosphorus pesticides in fresh legume vegetables, bulb vegetables and some fruits sold in Wenzhou, such as acetamiprid in bayberry and cowpea, dimethomorph in strawberry, chlorpyrifos in leek, etc., and monitoring of pesticide residues in food need to be strengthened.
