Objective: To understand the social security situation of current cases of pneumoconiosis in non-coal mine industries in Jiangsu Province, and to provide reference for the treatment and security work of pneumoconiosis patients. Methods: From January to October 2020, a follow-up survey was conducted on 4038 cases of pneumoconiosis in non-coal mine industries of the province from October 1949 to December 2019. The age, type of pneumoconiosis, industry type, and social security status of the patients were collected. Namely, work-related injury insurance, employer compensation, basic medical insurance for urban and rural residents, major illness insurance, etc. SPSS 19.0 was used for statistical description and analysis. Results: The cases of pneumoconiosis in non-coal mine industries in Jiangsu Province ranged in age from 36 to 105 (70.78±8.43) years old, and had been exposed to dust for 1 to 55 (19.27±9.29) years. Silicosis was the main form (3875 cases, 95.96%), and non-metallic mining and dressing industry was the main form (2618 cases, 64.83%). A total of 3991 cases (98.84%) of pneumoconiosis patients enjoyed social security, most of them were urban and rural residents with basic medical insurance (3624 cases, 89.75%), but there were still 47 patients without any social security. 15 cases (0.37%) enjoyed the subsistence allowance, with the monthly allowance amount ranging from 104 to 3960 yuan, with the average amount of 954.87 yuan/month. Conclusion: In Jiangsu Province, the proportion of pneumoconiosis patients in non-coal mine industries enjoying social security is relatively high, but there are still patients who do not enjoy any social security, and the difference in the amount of subsistence allowance is slightly larger. It is necessary to further improve the medical security of pneumoconiosis patients and improve their quality of life.

Objective:To explore the method of developing a canal-shaped implant template using a combined automatic pre-planning and 3D printing technology, and assess its impact on dose and efficacy improvement.Methods:Retrospective analysis of 15 patients with advanced cervical cancer admitted to the Affiliated Cancer Hospital of Guangxi Medical University from September 2020 to September 2022 was performed. Patients had characteristics such as vaginal stump recurrence, tumor eccentric growth, and previous hysterotomy, etc. Three-dimensional images were obtained by CT scan after automatic pre-planning. The PMT 3D software was used to analyze digital imaging and communications in medicine (DICOM) radiotherapy data, capture the coordinates of the pre-planned stay points to establish the implant channel, and generate the size and shape of the canal-shaped implant template based on patients' physiological structure. Dosimetric parameters, such as conformity index (CI), were evaluated. The changes of tumor size before and after treatment were analyzed by paired t-test. Results:Fifteen patients were treated with the canal-shaped implant template. The CI was 0.74±0.26, the total radiation dose (HR-CTV) D 90% (EQD 2, α/β=10) was (85.5±6.8) Gy, and the D 2 cm3 (EQD 2, α/β=3)for bladder, rectum, small intestine, and colon were (72.2±4.2), (65.8±6.1), (65.2±4.4), and (69.8±3.7) Gy, respectively, meeting clinical needs. After the treatment, the tumor volume was significantly decreased. The template had a good fit with the vaginal cavity, and a small amount of air gap on the sidewall did not affect the dose. Non-parallel needle insertion increased the utilization of the cavity space and implant needles. Conclusion:The method of developing the canal-shaped implant template using automatic pre-planning and 3D printing technology is efficient and effective, meets the requirements of modern precise radiotherapy, and has practical clinical value.

@#To investigate the effect of nucleoside diphosphate kinase (NDK) on the synthesis of hyaluronic acid, nucleoside diphosphate kinase gene (ndk) was overexpressed along with the hyaluronic acid-producing genes in recombinant B.subtilis. Two engineered strains named Hp8tg and Pn8tg were constructed.Uniform hyaluronic acid (HA) could be obtained from both engineered strains.HA produced by both recombinant strains was confirmed by monosaccharide composition analysis, Fourier transform infrared spectometry and nuclear magnetic resonance spectroscopy.Inducing conditions of HA fermentation were optimized by response surface methodology.Overexpression of ndk could increase the production and molecular weight of HA by 1.3-fold and 1.1-fold, respectively. This study revealed for the first time that overexpression of ndk could relieve the inhibition effect of uridine diphosphate (UDP) on Class II HA synthase and increase the production and molecular weight of HA, which proves to be an efficient strategy for the production of HA, and the preparation of other polysaccharides.

Objective: To understand the incidence of pneumoconiosis in the non-coal mining industry in Jiangsu Province, and provide reference for the prevention and control of pneumoconiosis in the non-coal mining industry. Methods: The data of 7019 newly diagnosed pneumoconiosis patients in non-coal mining industry in Jiangsu Province from January 1956 to December 2019 were collected through the Jiangsu Province Pneumoconiosis Follow-up Network Report System, including the gender of the pneumoconiosis patients, the name of the employer and the location, the industry classification of the employer, the duration of dust exposure in dust exposure, the name of occupational pneumoconiosis disease, the date of diagnosis of pneumoconiosis, etc. The collected case data of patients with pneumoconiosis were entered into the statistical software, and the characteristics of the patients' diagnosis time, region and industry were analyzed. Results: The number of confirmed pneumoconiosis patients in the non-coal mining industry in Jiangsu Province was mostly in 2007 (395 cases) , concentrated in Wuxi City (40.96%, 2875/7019) and Suzhou City (27.72%, 1946/7019) . The industries to which the patients belonged were mainly non-metallic mining and dressing (60.95%, 4278/7019) , and the most common type of pneumoconiosis was silicosis (96.40%, 6766/7019) . The patients were mainly stageⅠpneumoconiosis (61.33%, 4305/7019) . There were statistically significant differences in the mean age of diagnosis and the average duration of dust exposure among patients with different pneumoconiosis stages (P<0.01) . The differences in the average diagnosis age and the average duration of dust exposure of patients with different types of pneumoconiosis were statistically significant (P<0.05) , the mean age of diagnosis and the average duration of dust exposure of electric welders were the smallest, which were (44.92±7.74) years old and (17.38±10.15) years, respectively. Conclusion: The regional and industry distribution characteristics of new pneumoconiosis patients in the non-coal mining industry in Jiangsu Province are obvious, and attention should be paid to the treatment of pneumoconiosis patients with young diagnosed age and short duration of dust exposure, as well as the personal protection and health protection of front-line workers such as electric welders who are exposed to productive dust in a short period of time.

Objective:To evaluate the mid-term clinical efficacy of drug-coated balloons (DCB)in the treatment of femoro-popliteal artery TASC Ⅱ C/D de novo stenosis and in-stent restenosis.Methods:A total of 126 patients with TASC Ⅱ C/D femoro-popliteal artery stenosis treated with DCB in Renji Hospital and Pudong New Area People's Hospital from December 2016 to August 2020 were retrospectively enrolled, including 74 cases of de novo stenosis (de novo group) and 52 cases of in-stent restenosis (ISR group). The clinical data and lesion characteristics were analyzed; the primary patency rate, primary-assisted patency rate, secondary patency rate, and the freedom from target lesion revascularization (f-TLR)rate were evaluated; the perioperative complications, mortality and amputation rate were compared between two groups. Kaplan-Meier method was used to evaluate the patency rate of target vessel lesions, and Cox regression analysis was used to evaluate the relative risk factors.Results:There were 6 patients died in each group during the followup period. The lesion length of the de novo and ISR groups were (21.25±12.64) cm and (34.71±12.02) cm, respectively( t=33.74, P<0.001). The popliteal artery involvement was 33.8% (25/74) in the de novo group and 15.4% (8/52) in the ISR group (χ 2=5.35, P=0.021). The operational success rate was 100.0% in both groups, and the perioperative complication rate was 6.8% (5/74) in the de novo group and 1.9% (1/52) in ISR group. The median follow-up time was 22 month and 17 months; the mean follow-up time were(19.78 ± 11.02) months and (20.02 ± 11.32) months in the de novo group and ISR group, respectively. The primary patency rates at 6, 12 and 24 months after intervention were 89.1%, 73.4%, 50.8% in the Denovo group, and 87.8%, 68.8%, 42.0% in the ISR group, respectively; the primary assisted patency rate was 90.7%, 78.4%, 62.8% in the de novo group, and 89.3%,77.1%, 62.8% in the ISR group, respectively; the secondary patency rate was 95.1%,95.1%, 88.7% in de novo group, and 94.9%, 88.9%, 84.3% in ISR group, respectively; the f-TLR rate was 97.3%, 88.6%, 79.2% in de novo group, and 90.0%, 77.7%, 74.7% in ISR group, respectively (all P>0.05). Cox regression analysis showed that P2 and P3 segment involvement of the popliteal artery were independent factors affecting the patency rate of target lesion. Conclusions:The mid-term clinical efficacy of DCB in the treatment of TASC Ⅱ C/D femoro-popliteal artery de novo stenosis and in-stent restenosis is satisfactory.

BACKGROUND@#Arteriosclerosis obliterans (ASO) is a major cause of adult limb loss worldwide. Autophagy of vascular endothelial cell (VEC) contributes to the ASO progression. However, the molecular mechanism that controls VEC autophagy remains unclear. In this study, we aimed to explore the role of the GRB2 associated binding protein 1 (GAB1) in regulating VEC autophagy.@*METHODS@#In vivo and in vitro studies were applied to determine the loss of adapt protein GAB1 in association with ASO progression. Histological GAB1 expression was measured in sclerotic vascular intima and normal vascular intima. Gain- and loss-of-function of GAB1 were applied in VEC to determine the effect and potential downstream signaling of GAB1.@*RESULTS@#The autophagy repressor p62 was significantly downregulated in ASO intima as compared to that in healthy donor (0.80 vs. 0.20, t = 6.43, P < 0.05). The expression level of GAB1 mRNA (1.00 vs. 0.24, t = 7.41, P < 0.05) and protein (0.72 vs. 0.21, t = 5.97, P < 0.05) was significantly decreased in ASO group as compared with the control group. Loss of GAB1 led to a remarkable decrease in LC3II (1.19 vs. 0.68, t = 5.99, P < 0.05), whereas overexpression of GAB1 significantly led to a decrease in LC3II level (0.41 vs. 0.93, t = 7.12, P < 0.05). Phosphorylation levels of JNK and p38 were significantly associated with gain- and loss-of-function of GAB1 protein.@*CONCLUSION@#Loss of GAB1 promotes VEC autophagy which is associated with ASO. GAB1 and its downstream signaling might be potential therapeutic targets for ASO treatment.

Objective:To investigate whether the clinical efficacy of mechanical pharmacothrombectomy (PMT) in treatment of whole-lower-limb acute deep vein thrombosis (DVT) could be improved by the modified approach removing popliteal vein thrombosis.Methods:From Mar 2016 to Mar 2018, 31 patients with whole-lower-limb acute DVT were enrolled and treated with PMT by AngioJet. The clinical data was retrospectively analyzed, and the clinical efficacy was evaluated.Results:26 cases were treated by contralateral common femoral vein approach and the other 5 cases by ipsilateral calf deep vein. Urokinase was given in bolus in 29 patients before thrombectomy. After PMT, 7 cases combined with catheter-directed thrombolysis. 26 cases underwent iliac vein PTA, and 14 cases underwent iliac vein stenting. The average hospitalization days was (7.6±1.8) d. The thrombus clearance rate was grade Ⅱ (50%~99%) in 16 cases (51.6%) and grade Ⅲ (100%) in 15 cases (48.4%). 30 patients were followed up and the mean follow-up time was 19.7 months. The 12-month primary patency rate was 83.3%. All the 5 patients with occlusion had different degrees of post-thrombotic syndrome (PTS), and the incidence of PTS was 16.7% (5/30).Conclusions:The modified approach to treat the whole-lower-limb acute deep vein thrombosis with PMT is safe and effective. The popliteal vein thrombosis can be cleared in one stage. The blood inflow can be improved, and the incidence of PTS is relatively low.

Objective To explore a more objective scheme for comprehensive evaluation of township health education program. Methods Based on the indicators and grading results of 17 township hospitals (named from A to Q) in Xiangshan County, we calculated the weight of each indicator by entropy weight method and sorted the township hospitals by the improved TOPSIS. Then we compared the ranking with the annual assessment results in 2017 to verify the rationality of this scheme. Results The entropy weights of"printed materials of health education","play of audio-visual materials","health education bulletin board","public health consultation" ,"health knowledge lecture" ,"individualized health education" and"awareness rate of health knowledge"were 0.122 0, 0.125 3, 0.134 6, 0.157 2, 0.157 0, 0.179 8 and 0.124 1, respectively. Through the improved TOPSIS, 17 hospitals were sorted as follows: P, L, O, C, G, A, H, N, B, E, M, Q, K, J, F, D, I. Compared with the annual assessment rankings which were P, L, A, C, B, O, G, H, K, N, D, E, M, J, I, F, Q, thirteen of them were different. Conclusion "Printed materials of health education","awareness rate of health knowledge" and"play of audio-visual materials" have little room for improvement, while"individualized health education" should be focused on in the future. The improved TOPSIS based on entropy weight could objectively evaluate the quality of health education service.

Objective To investigate the antagonistic effect of ω-3PUFAs on cognitive impairment in MK-801-induced schizophrenia (SZ) rats and its mechanism.Methods Rat model of schizophrenia was induced by MK-801.Morris water maze was used to detect the change of cognitive function in rats.The number of neonatal neurons in hippocampus was detected by Brdu staining.CREB,p-CREB,BDNF,TrkB and p-TrkB levels were detected by Weston Blot.Results MK-801 induced schizophrenia-like cognitive impairment (the escape latency in the water maze test was (6.51±3.10)s for Ctr group,(15.27±6.20)s for Mod group;acrossing times was (4.63±1.06) times for Ctr group,(2.00±1.15) times for Mod group),reduced the number of neonatal neurons in hippocampus (the relative level of neonatal neuron number per unit area,Mod/Ctr was 0.656±0.066) and impaired the CREB/BDNF/TrkB pathway (the relative level of gray value,Mod/Ctr:CREB was 0.393±0.065,p-CREB was 0.591±0.015,BDNF was 0.716±0.115,TrkB was 0.787±0.029,p-TrkB was 0.586±0.013).ω-3PUFAs improved the CREB/BDNF/TrkB pathway activity by increasing CREB and TrKB level and their phosphorylation (the relative level of gray value,Pre/Ctr:CREB was 1.139±0.111,p-CREB was 0.845±0.243,BDNF was 0.864±0.133,TrkB was 0.916±0.022,p-TrkB was 0.952±0.047),and then recovered the number of neonatal neurons in hippocampus (the relative level of neonatal neuron number per unit area,Pre/ Ctr was 1.183±0.101),thereby reduced the cognitive dysfunction in schizophrenia rats(the escape latency in the water maze was (7.44±4.55)s for Pre;acrossing times was (3.86±1.68) times for Pre).Conclusion ω-3PUFAs can relieve the MK-801-induced schizophrenia-like cognitive impairment.
