[Purpose]To analyze the incidence and mortality of lung cancer in Zhejiang cancer regi-stration areas in 2021 and trends from 2000 to 2021.[Methods]Using data from Zhejiang cancer registration areas from 2000 to 2021,the crude rate,age-standardized rate by Chinese standard population(ASRC)and the world standard population(ASRW),and composition ratio were calcu-lated to describe the incidence and mortality in 2021.Joinpoint regression was employed to ana-lyze temporal trends over the 22 years,calculating the annual percentage change(APC),average annual percentage change(AAPC),and their 95％confidence intervals(CI).[Results]The crude incidence rate of lung cancer in 2021 was 128.58/105,with an ASRC of 68.74/105,ac-counting for 24.22％of all cancers;the crude mortality rate was 51.55/105,with an ASRC of 21.58/105,constituting 27.98％of all cancer deaths.Both crude incidence rate(AAPC=5.73％,P＜0.001)and ASIRC(AAPC=4.14％,P＜0.001)of lung cancer showed significant increasing trends from 2000 to 2021.The crude mortality rate increased slowly(AAPC=1.76％,P＜0.001),while the ASMRC(AAPC=-0.40％,P=0.035)exhibited a modest decline.The increase in incidence was more pronounced in females than males,though no statistically significant difference was observed in mortality trends.The incidence rates in urban and rural areas showed similar growth trends;the crude mortality rate in rural areas was growing significantly faster than that in urban areas,and the decline in the ASRC was only statistically significant in urban areas.The incidence rate was in-creasing in all age groups.The mortality rate was declining among younger people(＜65 years old).The age group of 15～44 years old demonstrated a greater increase in incidence and a sharper decline in mortality than those aged 45 years old and above.[Conclusion]From 2000 to 2021,Zhejiang Province experienced a marked rise in lung cancer incidence with escalating disease burden.Despite severe population aging,ASRC of mortality declined steadily,reflecting effective prevention and control measures.

Sonodynamic therapy（SDT）has garnered significant attention in cancer treatment modalities due to its superior tissue penetration capabilities，non-invasive approach，and controllability. SDT operates by utilizing sonosensitizers and ultrasound-responsive devices to induce the production of reactive oxygen species（ROS）under ultrasound stimulation，thereby eliciting immunogenic cell death（ICD）in tumor cells and the release of damage-associated molecular patterns，which in turn trigger an immune response against the tumor.However，the tumor microenvironment often results in a relatively weak immune response post-cancer treatment. To address this issue，extensive research is being conducted on combining SDT with immunotherapy，particularly focusing on immune checkpoint blockade（ICB）therapies. This review synthesizes the mechanisms of SDT，its integration with immunotherapy，especially ICB therapies，and the current state of research，with the objective of providing strategic guidance for the advancement of sonodynamic immunotherapy.

Objective To investigate the effects of different dosages of atorvastatin, rosuvastatin, and simvastatin in elderly patients with ST-segment elevation acute myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). Methods A total of 180 patients with STEMI undergoing PCI were prospectively selected as study subjects and divided into group A, group B, group C, group D, group E, and group F using a random number table method, with 30 patients in each group. The group A received low-dose simvastatin orally, the group B received high-dose simvastatin orally, the group C received low-dose atorvastatin orally, the group D received high-dose atorvastatin orally, the group E received low-dose rosuvastatin orally, and the group F received high-dose rosuvastatin orally. The levels of serum inflammatory factors[interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), high-sensitivity C-reactive protein (hs-CRP)], myocardial injury markers[creatine kinase isoenzyme (CK-MB), cardiac troponin T (cTnT), N-terminal pro-brain natriuretic peptide (NT-proBNP)], cardiac function indicators[left ventricular ejection fraction (LVEF), cardiac index (CI), cardiac output (CO)], as well as the ST-segment resolution, occurrence of adverse cardiovascular events, and adverse reactions were compared among the groups. Results At 1 day and 1 month postoperatively, the levels of IL-6, hs-CRP, and TNF-α decreased successively in groups A, B, C, D, E, and F(P < 0.05). At 1 day and 1 month postoperatively, the levels of cTnT, CK-MB, and NT-proBNP also decreased successively in the groups A, B, C, D, E, and F (P < 0.05). At 1 month postoperatively, the LVEF, CO, and CI increased successively in the groups A, B, C, D, E, and F (P < 0.05). The proportions of patients with ST-segment resolution successively increased in the groups A, B, C, D, E, and F (P < 0.05). There were no statistically significant differences in the total incidence of adverse cardiovascular events and adverse reactions among the groups (P>0.05). Conclusion Both low-dose and high-dose atorvastatin, rosuvastatin, and simvastatin can effectively relieve inflammation reactions, improve myocardial function, and promote ST-segment resolution in elderly patients with STEMI undergoing PCI, with high-dose rosuvastatin showing the best effect.

Objective:To investigate the efficacy of primary closure versus T-tube drainage in patients with common bile duct stones after laparoscopic common bile duct exploration and stone extraction. Methods:Fifty-two patients with common bile duct stones who received treatment at The Second Affiliated Hospital of Guizhou Medical University between February 2021 and February 2023 were included in this study. All patients underwent laparoscopic common bile duct exploration and stone extraction and then were divided into two groups ( n = 26 per group) using a randomized controlled trial design with allocation based on a random number table. The control group received T-tube drainage postoperatively, whereas the observation group underwent primary suture treatment. Both groups were observed for 3 days postoperatively to compare various postoperative clinical indicators, including serum levels of cortisol, adrenaline, C-reactive protein, interleukin-6, direct bilirubin, total bile acid, alkaline phosphatase, and gamma-glutamyl transferase, and the occurrence of postoperative complications. Results:The operative time in the observation group was significantly shorter than that in the control group [(105.30 ± 5.89) minutes vs. (121.36 ± 5.86) minutes, t = 9.86, P < 0.001]. The intraoperative blood loss in the observation group was significantly less than that in the control group [(40.31 ± 4.53) mL vs. (45.20 ± 4.76) mL, t = 3.80, P < 0.001]. The length of hospital stay in the observation group was significantly shorter than that in the control group [(12.01 ± 2.86) days vs. (14.32 ± 2.73) days, t = 2.98, P = 0.005]. The gastrointestinal function recovery time in the observation group was shorter than that in the control group [(31.42 ± 2.59) days vs. (37.62 ± 2.63) days, t = 8.57, P < 0.001]. The bile drainage volume in the observation group was less than that in the control group [(168.69 ± 15.41) mL vs. (275.62 ± 15.32) mL, t = 25.09, P < 0.001]. The serum level of cortisol in the observation group was significantly higher than that in the control group [(469.63 ± 20.62) mmol/L vs. (359.65 ± 19.87) mmol/L, t = 19.58, P < 0.001]. The serum level of adrenaline in the observation group was significantly higher than that in the control group [(274.62 ± 20.21) ng/L vs. (198.64 ± 20.16) ng/L, t = 13.57, P < 0.001]. The serum level of C-reactive protein in the observation group was significantly higher than that in the control group [(3.42 ± 0.37) mg/L vs. (2.74 ± 0.25) mg/L, t = 7.77, P < 0.001]. The serum level of interleukin-6 in the observation group was significantly higher than that in the control group [(112.36 ± 8.94) μg/L vs. (87.62 ± 8.63) μg/L, t = 10.15, P < 0.001]. The serum level of direct bilirubin in the observation group was significantly lower than that in the control group [(24.52 ± 4.62) μmol/L vs. (35.62 ± 4.87) μmol/L, t = 8.43, P < 0.001]. The serum level of total bile acid in the observation group was significantly lower than that in the control group [(10.62 ± 4.21) U/L vs. (17.64 ± 4.16) U/L, t = 6.05, P < 0.001]. The serum level of alkaline phosphatase in the observation group was significantly lower than that in the control group [(100.21 ± 10.24) mg/L vs. (112.74 ± 11.25) mg/L, t = 4.20, P < 0.001]. The serum level of gamma-glutamyl transferase in the observation group was significantly lower than that in the control group [(122.36 ± 8.94) μg/L vs. (142.62 ± 5.63) μg/L, t = 9.78, P < 0.001]. The incidence of complications in the observation group was significantly lower than that in the control group [7.69% (2/26) vs. 30.77% (8/26), χ2 = 4.46, P = 0.035]. Conclusion:Compared with T-tube drainage, primary closure following laparoscopic common bile duct exploration and stone extraction can reduce patient stress responses, improve liver function, shorten postoperative recovery time, and result in a lower incidence of complications.

Objective:To study the clinical effects of modified surgical method with H-uvulopalatopharyngoplasty(H-UPPP)and traditional surgical method in the treatment of obstructive sleep apnea hypopnea syndrome(OSAHS)in children.Methods:The clini-cal data of 364 pediatric patients with OSAHS were retrospectively analyzed.The patients were divided into 2 groups and treated by low-temperature plasma knife radio frequency ablation for bilateral tonsil removal combined with H-UPPP(group A,n=204)and low-temperature plasma knife radio frequency ablation only(group B,n=160)respectively.The operative time,intraoperative bleed-ing,postoperative secondary bleeding,VAS of pain following operation,postoperative traumatic white film shedding time,OAH1,LSaO2,ESS scores and complications of the 2 groups were compared.Results:In group A the operative time,intraoperative bleed-ing,VAS,OAHI and ESS scores were lower than those in group B(P＜0.05),wile postoperative traumatic white film detachment time and LSaO2 were higher(P＜0.05).No statistically significant difference in terms of the number of cases of postoperative seconda-ry bleeding and complications was observed between the 2 groups(P＞0.05).Conclusion:The combination of low-temperature plas-ma radio frequency ablation and H-UPPP for the treatment of OSAHS may provide clear intraoperative view,and may improve the treatment effects.

BACKGROUND:Studies have shown that both Panax notoginseng saponins and concentrated growth factor can promote fracture healing,but there are few studies addressing their combined effects on fracture healing.Panax notoginseng saponins may accelerate fracture healing by promoting the release of concentrated growth factor-related factors over a certain period of time. OBJECTIVE:To study the effect of Panax notoginseng saponins on concentrated growth factor release and fracture healing in rats. METHODS:Eighteen 8-week-old Sprague-Dawley rats were numbered and randomly divided into three groups:Panax notoginseng saponins group,model control group and blank group.Panax notoginseng saponins group was fed with Panax notoginseng saponins for 2 weeks.Model control group was given 2 mL of normal saline for 2 weeks and blank group was fed normally.Concentrated growth factor was obtained by the centrifugation method both from the Panax notoginseng saponins group and model control group.After 1 week of normal feeding,all animals underwent modeling for femoral fracture.The Panax notoginseng saponins group and the model control group were implanted with autologous concentrated growth factor,and then the release concentration of growth factors at different time points(1 hour,1,3,5,7,9 and 11 days)were measured by ELISA.Fracture healing was assessed based on postoperative X-ray and hematoxylin-eosin staining of bone tissues. RESULTS AND CONCLUSION:Compared with the model control group,the Panax notoginseng saponins group had higher release concentrations of vascular endothelial growth factor A and transforming growth factor β at 7,9,and 11 days,Platelet-derived growth factor BB at 5,9,and 11 days,and basic fibroblast growth factor at 1-11 days(P<0.01).X-ray examinations indicated that fracture healing in the Panax notoginseng saponins group was better than that in the model control group,and fracture healing in these two groups was better than that in the blank group at 2 months after surgery.Hematoxylin-eosin staining results found that the constituent osteocyte density in the Panax notoginseng saponins group was greater than that in the model control group,and the constituent osteocyte density in these two groups was better than that in the blank group.These findings indicate that Panax notoginseng saponins can increase the concentration of concentrated growth factor-related factors.After intervention with Panax notoginseng saponins,concentrated growth factors are more advantageous in promoting fracture healing in rats.

Objective:To investigate the relationship between parathyroid hormone（PTH） level and permanent hypoparathyroidism（PHPP） on the first day after radical papillary thyroidectomy, and its predictive value. Methods:A total of 80 patients with papillary thyroid cancer who underwent total thyroid resection and central lymph node dissection were collected and analyzed from January 2021 to January 2022. According to whether PHPP occurred after surgery, the patients were divided into hypoparathyroidism group and normal parathyroid function group, and univariate and binary logistics regression were used to analyze the correlation between PTH and serum calcium levels and PHPP on the first day after surgery in two groups. The dynamic changes of PTH at different time points after operation were analyzed. The area under the receiver operating characteristic was used to evaluate the predictive power of PTH on the development of PHPP after surgery. Results:Among the 80 patients with papillary thyroid cancer, 10 cases developed PHPP, with an incidence rate of 12.5%. Binary logistics regression analysis showed that PTH on the first postoperative day（OR=14.534, 95%CI: 2.377-88.858, P=0.004） was an independent predictive risk factor for postoperative PHPP. Taking PTH=8.75 ng/L on the first postoperative day as the cut-off value, the AUC of the area under the curve was 0.874（95%CI: 0.790-0.958, P<0.001）, the sensitivity was 71.4%, the specificity was 100%, and the Yoden index was 0.714. Conclusion:PTH level on the first day after total thyroid papillary carcinoma surgery is closely related to PHPP, and is an independent predictor of PHPP.

Objectives To investigate the effects of low level of ambient NO₂ on the death of cardiovascular and cerebrovascular diseases in Enshi city and to identify sensitive population, so as to provide a scientific basis for formulating health policies. Methods The data of air pollutants, meteorological factors and death of cardiovascular and cerebrovascular diseases in Enshi city from 2015 to 2018 were collected. The generalized additive model based on Poisson distribution was used to analyze the effects of low ambient NO₂ level on the death risk of cardiovascular and cerebrovascular diseases in Enshi city. A subgroup analysis was performed on age, gender, and season. Results The average concentrations of major gaseous air pollutants in Enshi city from 2015 to 2018 were NO₂ (21.40 μg/m³), SO₂ (9.68 μg/m³), CO (0.88 mg/m³), and O₃ (61.21 μg/m³), respectively, all of which did not exceed the national secondary standard. The results of single pollutant model analysis showed that each 1 μg/m3 increase in NO₂ concentration in lag0 day was associated with a 0.33% increase (95% CI: 0.06 - 0.72) (P>0.05) in mortality risk of cardiovascular and cerebrovascular diseases. In the female population, each 1 μg/m3 increase in NO2 concentration in lag01 day was associated with a 0.92% increase (95% CI: 0.26 - 1.56) (P<0.05) in mortality risk of cardiovascular and cerebrovascular diseases. In the cold season, each 1 μg/m3 increase in NO₂ concentration in lag0 day was associated with a 0.62% increase (95% CI: 0.12 - 1.12) (P<0.05) in mortality risk of cardiovascular and cerebrovascular diseases. The results of the two-pollutant model showed that after controlling other gaseous pollutants (SO₂, CO or O₃), the effect of NO₂ on the mortality risk of cardiovascular and cerebrovascular diseases in women and the whole population in cold season still existed. Conclusion The low ambient level of NO₂ in Enshi city was significantly associated with increased mortality risk of cardiovascular and cerebrovascular diseases in female population as well as in cold seasons in the whole population. Attention should be paid to the health protection of special populations in areas with low ambient pollution level of NO₂ in special seasons.
