Objective: To investigate the trends in incidence and epidemiological characteristics of notifiable infectious diseases in Huzhou City, Zhejiang Province from 2005 to 2023, so as to provide insights into optimizing infectious disease surveillance and control. Methods: Data of notifiable infectious disease cases in Huzhou City from 2005 to 2023 were collected from the Infectious Disease Report Information System of Chinese Disease Prevention and Control Information System. Trends in incidence were analyzed using annual percent change (APC) and average annual percent change (AAPC). The population distribution and seasonal characteristics were descriptively analyzed. Results: From 2005 to 2023, a total of 504 283 cases of notifiable infectious diseases were reported in Huzhou City, with an annual crude incidence rate of 892.65/105 and a standardized incidence rate of 989.21/105. The incidence rate of notifiable infectious diseases in Huzhou City showed an upward trend (AAPC=8.886%, P<0.05), of which there was an obvious upward trend from 2021 to 2023 (APC=95.996%, P<0.05). After the removal of COVID-19 incidence, the incidence trend was basically unchanged (AAPC=7.970%, P<0.05). From 2005 to 2023, the incidence rate of class A and B notifiable infectious diseases showed no obvious trend (P>0.05), and the incidence rate of class A and B respiratory infectious diseases showed an upward trend (AAPC=6.958%, P<0.05). After the removal of COVID-19 incidence, the two showed a downward trend (AAPC=-7.680% and -8.660%, both P<0.05). The incidence rate of class A and class B intestinal infectious diseases, blood-borne and sexually transmitted infectious diseases showed a downward trend (AAPC=-14.849% and -5.977%, both P<0.05), while the incidence rates of natural and insect-borne infectious diseases did not show a significant trend (P>0.05). The overall incidence rate of class C infectious diseases showed an upward trend (AAPC=13.058%, P<0.05). The incidence rate ratio (IRR) of notifiable infectious diseases between males and females was 1.26 (95%CI: 1.25-1.27). A total of 204 043 cases under 10 years were reported, accounting for 40.46%. The peak incidence of class A and B respiratory infectious diseases was in January, May and June, while that of class A and B intestinal infectious diseases was from June to October. The peak incidence of class C respiratory infectious diseases was in January, March, April and December, while that of class C intestinal infectious diseases was from May to August and from November to December. Conclusions The incidence rate of notifiable infectious diseases in Huzhou City showed an upward trend from 2005 to 2023, which was more obvious from 2021 to 2023. Men and children under 10 years were the high-risk population. The incidence of respiratory and intestinal infectious diseases had obvious seasonal characteristics.

Objective : To understand the epidemiological characteristics of notifiable respiratory infectious diseases in Huzhou City, Zhejiang Province from 2017 to 2022, so as to provide insights into formulation of respiratory infectious disease prevention and control strategies. Methods: The data pertaining to notifiable respiratory infectious disease in Huzhou City from 2017 to 2022 were collected through the Infectious Disease Report Information System of Chinese Disease Prevention and Control Information System. Epidemiological characteristics of notifiable respiratory infectious disease was analyzed using a descriptive epidemiological method. : Results Conclusions: A total of 31 314 cases of notifiable respiratory infectious diseases were reported in Huzhou City from 2017 to 2022, with an average annual reported incidence of 169.12/105. The reported incidence of notifiable respiratory infectious diseases appeared a tendency towards a rise in Huzhou City from 2017 to 2022 (P<0.05). The top six reported diseases in terms of case numbers were influenza (20 048 cases), tuberculosis (6 920 cases), COVID-19 (1 893 cases), mumps (1 413 cases), pertussis (475 cases) and scarlet fever (442 cases), accounting for 99.61% of the total cases. The incidence of influenza, COVID-19 and pertussis showed a tendency towards a rise, the incidence of mumps and tuberculosis showed a tendency towards a decline (all P<0.05), and scarlet fever remained at a low-level incidence (P>0.05). Respiratory infectious diseases were mainly reported in winter (January, February and December), with 14 644 cases accounting for 46.77%. There were 15 068 cases reported in schools and kindergartens, accounting for 48.12%. The incidence showed a U-shaped variation with age, with the highest incidence in residents at ages of 10 years and below (987.68/105), and showing a tendency towards a rise in residents at ages of 60 years and above. The incidence of respiratory infectious diseases in Huzhou City from 2017 to 2022 increased significantly. Influenza, tuberculosis, COVID-19, mumps and pertussis are key notifiable respiratory infectious diseases. Residents at ages of 10 years and below and 60 years and above should be given a high priority for respiratory infectious disease control.

AIM: To investigate the pharmacokinetic properties of the main active components of Dalitong extract in SD rats after oral administration using UPLC-MS / MS. METHODS: An UPLC-MS / MS method was established to simultaneously detect tetrahydropalmatine, nobiletin and costunolide in the plasma and tissues of SD rats. The method was applied to investigate the pharmacokinetic characteristics and tissue distribution. RESULTS: After a single oral administration, the three active components were rapidly absorbed into the body, with a peak concentration (Cmax) of (13.73 ± 7.50), (27.01 ± 17.69) and (6.73 ± 29.94) ng / mL for tetrahydropalmatine, nobiletin, and costunolide, respectively. The time to reach the peak concentration (Tmax) was (1.40 ± 0.93), (0.63 ± 0.28) and (2.38 ± 8.81) h, respectively. The area under the curve (AUC) was (80.43±40.03), (41.30±28.69) and (303.90 ± 136.69) ng · h · mL

Objective To compare the efficacy of double filtration plasmapheresis(DFPP),centrifugal therapeutic plasma exchange(cTPE)and centrifugation-filtration plasmapheresis(CFPP)in improving renal insufficiency after kidney transplantation,as well as the differences in inducing plasma exchange-related adverse reactions.Methods Clinical data from 46 patients who underwent plasma exchange after renal transplantation in our hospital were retrospectively collected,and patiens were divided into DFPP group(n=33),cTPE group(n=7)and CFPP group(n=6).Changes in peripheral blood creatinine,albumin,hemoglobin,platelets,fibrinogen levels and urine volume before and after TPE were compared and analyzed among the three groups.Results Among the DFPP group,cTPE group and CFPP group,the creatinine after TPE decreased by(31.40±25.38)%,(58.91±19.75)%and(39.44±28.64)%,respectively,with cTPE group significant-ly higher than the DFPP group(P＜0.05),but no significant differences between the DFPP group and cTPE group(P＞0.05);the urine volume after TPE increased by(49.33±30.03)%,(54.62±39.32)%and(68.89±23.00)%,showing no significant differences(P＞0.05);the hemoglobin after TPE decreased by(11.97±5.94)%,(20.17±5.75)%and(9.65±8.75)%,respectively,with the cTPE group significantly higher than the DFPP group and CFPP group(P＜0.05),but no significant difference between the DFPP group and CFPP group(P＞0.05).The platelet count after TPE decreased by(37.88±18.39)%,(24.56±12.36)%and(21.40±12.51)%,respectively,with no significant differences between the three groups(P＞0.05);the fibrinogen after TPE decreased by(0.57±0.20)%,(0.14±0.06)%and(0.26±0.22)%,re-spectively,with the DFPP group significantly higher than the cTPE group(P＜0.05),but the CFPP group had no significant difference with cTPE group or DFPP group(P＞0.05);the albumin after TPE decreased by(11.41±5.97)%,(14.67±6.52)%and(25.18±5.10)%,respectively,with cTPE group and DFPP group significantly lower than the CFPP group(P＜0.05,P＜0.001),but with no significant difference between the DFPP group and cTPE group(P＞0.05).Conclusion The effect of three plasma exchange methods varies on renal function,anemia and coagulation function of patients after kid-ney transplantation.It is necessary to consider the the patient's disease characteristics and treatment needs,as well as the laboratory′s technical conditions and plasma supply when selecting TPE methods.

Objective:Explore the feasibility and advantages of using proximal and distal ends of thoracodosal artery and vein as recipient vessels in deep inferior epigastric perforator flap immediate breast reconstruction.Methods:The clinical data of patients who underwent breast reconstruction surgery using the proximal and distal ends of the thoracodorsal vein as recipient vessels at the Department of Breast and Thyroid Surgery of the Second Affiliated Hospital of Hainan Medical University from March 2022 to June 2023 were analyzed retrospectively. Preoperative examinations included thoracoabdominal angiography and color Doppler ultrasonic localization of the main trunk and perforators of the inferior epigastric vessels. The procedure began with mastectomy and axillary lymph node dissection, followed by the isolation of bilateral perforators and the main trunk of the abdominal flap. The main trunks of the bilateral inferior epigastric arteries were then transected, and their vascular pedicles exposed and anastomosed respectively to the proximal and distal ends of the thoracodorsal artery and vein. Both arteries and veins were joined end-to-end. The flap after trimming and reconstruction was then implanted into the cavity left after mastectomy through the incision. Breast positioning was performed with the patient in a knee-bent and hip-flexed position. After adjusting the shape of the reconstructed breast. The donor site was closed, the umbilicus was reconstructed, drainage tubes were placed, and the breast incision was closed. Postoperative follow-up monitored complications associated with the flap and patient satisfaction with the breast reconstruction, utilizing a self-assessment method.Results:Four female patients were included, aged (46.0±6.5) years, ranging from 37 to 52 years. All four patients had bilateral vascular pedicles in the donor area, with three patients having thoracodorsal vessels at the distal and proximal ends as recipient vessels, and one patient having anterior serratus branch of the thoracodorsal vessels at the distal and proximal ends. All drainage tubes were removed within 7 to 10 days after surgery. Patients were discharged. Follow-up period ranged from 1 to 15 months, averaging 6 months. The patients recovered well postoperatively, with no flap-related complications occurring. All four patients were satisfied with the result of the reconstruction.Conclusion:The simultaneous application of the proximal and distal ends of the thoracodorsal artery and vein can ensure the safety of flap survival while reducing damage to the ribs and intercostal muscles, achieving better aesthetic result.

Objective:To modify the blepharoplasty through palpebral margin incision with preservaton of the pretarsal orbicularis oculi muscle, and to discuss the clinical application effects.Methods:The clinical data of patients who underwent double-eyelid blepharoplasty through palpebral margin incision with preservation of the pretarsal orbicularis oculi muscle were retrospectively analyzed from August 2021 to August 2023 in Changsha Aist Medical Cosmetology Hospital. After the skin peeling rang was designed, the skin was removed, tissue was separated under the orbicularis oculi muscle. The pretarsal orbicularis oculi muscle was thinned-shaped at the upper edge of tarsus as wedge-shaped, and was detached from the upper edge of tarsus. The pretarsal fascia or levator aponeurosis was fixed internally with the orbicularis oculi muscle at the position of the double-eyelid crease. After confirming the shape and symmetry of the double-eyelid, the skin was sutured. Incision healing, eyelid swelling and complications were observed, and double-eyelid morphology was followed up. Six months after surgery, the patients’ satisfaction with the surgical effect (satisfied, somewhat satisfied, dissatisfied) was investigated, and the upper eyelid scar status (including pigmentation, thickness, vascularity, and pliability) was scored using the Vancouver scar scale (VSS). The higher the score, the more serious the scar was.Results:A total of 78 patients with single eyelid or subtle double eyelid were included, including 6 males and 72 females, aged 18-40 years old. All the patients underwent modified double-eyelid blepharoplasty through palpebral margin incision with preservation of the pretarsal orbicularis oculi muscle, 29 patients underwent ptosis correction simultaneously, and 47 patients underwent epicanthus correction simultaneously. The incision healed by first intention after the operation. 78 cases were followed up for 1 to 6 months, and slight upper eyelid swelling was eliminated in 71 cases at 10-15 days and in 7 cases at 25-30 days. Among them, 61 cases were followed up for 6 months, the creases of double-eyelid was natural and smooth, bilateral basic symmetry, and there were no adverse manifestations such as double-eyelid shallowing and pretarsal tissue pilling, and no complications such as incompleted eye-closure. 57 cases were satisfied with the results and 4 cases were somewhat satisfied. The incision scar was not obvious when the eyes were closed in 61 patients. The VSS score was close to 0, and the average score of pigmentation, thickness, vascularity, and pliability were 0.29, 0, 0.31 and 0 points, respectively.Conclusion:This operation method preserves almost all the pretarsal orbicularis oculi muscle to promote the healling of lymph circulation. After the orbicularis oculi muscle is choosed for internal fixation, this more simple operation method can not only guarantee the efficacy of double-eyelid blepharoplasty through palpebral margin incision, but also accelerate the healling of the eyelid after surgery and reduce the incidence of incompleted eye-closure.
