Objective:To study the effect of bridge orbicularis oculi muscle flap blepharoptosis in the treatment of post-burn scar contracture ectropion.Methods:The clinical data of patients wih post-burn cicatricial ectropion treated with bridge orbicularis oculi muscle flap from April 2006 to September 2020 of Department of Plastic Surgery, Affiliated Hangzhou First People’s Hospital, School of Medicine, Westlake University were analyzed retrospectively. For patients with severe eyelid scar contracture caused by head and face burns, after releasing the scar and resetting the eyelid margin, orbicularis oculi muscle flaps were made at the base of the upper and lower eyelid release incision, crossed the muscle flap over the eyelid adhesion point of the eye fissure, by performed bridge cross transfer, and fixed to the orbicularis oculi muscle at the base of the release incision to form eyelid adhesion. H-shaped full-thickness skin graft or medium-thickness skin graft was performed on the defect wound during the operation. Tie-over dressing fixation in the skin graft area. One year after the operation, it was confirmed that the skin graft was stable and there was no recurrence of ectropion, and then cut the adhesion. Follow-up for more than one year after the operation, foreign body sensation, conjunctival sac pusc, skin graft survival, success rate of eyelid adhesion, anti-stretching effect of muscle flap, skin retraction rate and complications were observed. The distances between eyelid margins preoperative and after incision of eyelid adhesion were measured. SPSS 25.0 software was used for data statistics, measurement data was represented by M ( Q1, Q3), and counting data was represented by cases. Results:Fourteen patients (23 eyes) were included in this study, including 11 males and 3 females, aged 41.5 (32.5, 47.0) years, and the time from burn to this treatment was 13.5 (10, 24) months. 5 cases (7 eyes) were not treated with skin grafting or blepharoptosis after burn, and 9 cases (16 eyes) were treated with blepharoptosis and/or skin transplantation. The area of skin graft during operation was 37 mm ×18 mm to 52 mm ×39 mm. Before operation, the distance between the upper and lower eyelid margins was 14 (12, 14) mm when eyes were open, and 6 (5, 9) mm when eyes were closed. After eyelid adhesion surgery, the patient had no foreign body sensation and infection, and all the skin grafts survived. The success rate of blepharoptosis was 100%, and there was no accidental rupture or elongation. The eyelid adhesions contracted synchronously when the patients closed their eyes, and the muscle flap had good anti-stretching effect. The duration of blepharoptosis was 13(12, 24) months, during which no complications or adverse reactions occurred. The average skin graft retraction rate was 9% (5%, 10%) in half a year. After incision of the orbicularis oculi muscle flap, the distance between the upper and lower eyelid margins was 9 (8, 9) mm when the eyes were open, and 0 (0, 0) mm when the eyes were closed.Conclusion:Bridge orbicularis oculi muscle flap tarsorrhaphy can provide long-term tarsorrhaphy, effectively reduce skin contracture after eyelid skin grafting, and has a stable therapeutic effect on postburn ectropion.

Objective:To investigate the epidemic situation of drinking water-borne endemic fluorosis in Henan Province, evaluate the effectiveness of prevention and control measures, and provide a basis for formulating further prevention and control policies.Methods:From April to November 2021, a census of all diseased villages registered in 112 drinking water-borne endemic fluorosis counties (cities, districts, hereinafter referred to as counties) of 17 provincial-level cities and 9 provincial-level counties (cities) in Henan Province was conducted to collect the basic information of diseased counties and villages. The content of fluoride in drinking water and the prevalence of dental fluorosis in children aged 8 - 12 years old were measured on a village by village basis.Results:By the end of 2021, drinking water-borne endemic fluorosis was prevalent in 112 diseased counties in Henan Province, involving 17 450 diseased villages. Among them, 17 433 villages had implemented measures to reduce fluoride and improve water quality, with a water improvement rate of 99.90% (17 433/17 450). There were 14 920 villages with qualified water, and the qualified rate of water fluoride was 85.50% (14 920/17 450). There were a total of 4 232 water improvement projects in all diseased villages, with a normal operation rate of 97.09% (4 109/4 232) and a qualified rate of 93.03% (3 937/4 232) for water fluoride in the projects. The total detection rate of dental fluorosis in children in the province was 9.64% (39 391/408 584), with moderate to severe dental fluorosis accounted for 8.08% (3 182/39 391), the dental fluorosis index was 0.18. The prevalence of fluorosis was negative.Conclusions:In 2021, the prevalence of drinking water-borne endemic fluorosis is widespread in Henan Province, and measures to reduce fluoride and improve water quality in diseased villages have been basically implemented. However, the fluoride content of water in some villages still does not meet the standard, and some water improvement projects cannot operate normally throughout the year. In the future, it is necessary to address the above issues one by one and consolidate the achievements in prevention and control of drinking water-borne endemic fluorosis.

Objective:To learn about the progress of prevention and control of drinking-water-borne endemic arsenic poisoning in Henan Province, and provide scientific basis for achieving the goal of eliminating high arsenic hazards as scheduled.Methods:From July to August 2019, in accordance with the requirements of the National Monitoring Program for Drinking-water-borne Endemic Arsenic Poisoning, a general survey was carried out in 26 high-arsenic villages in 6 counties of Henan Province to investigate the water improvement situation and the operation of water improvement projects, and the arsenic content in drinking water of households was measured, meanwhile, the arsenic poisoning status of permanent residents in high-arsenic villages was investigated.Results:All 26 villages with high arsenic content in the province had undergone water improvement, with a water improvement rate of 100.00%. A total of 18 water improvement projects were investigated in 26 high-arsenic villages, all of which were operating normally. Twenty-six water samples were collected, and the arsenic content in the household water was < 0.01 mg/L, which met the sanitary standards for drinking water. No patient of endemic arsenic poisoning was found during the survey.Conclusion:In Henan Province, the drinking-water-borne endemic arsenic poisoning has been effectively controlled, and the prevention and control achievements should continue to be consolidated in the future.

Objective:To master the provincial-level quality assessment of the self-inspection projects for control and evaluation of drinking water-borne endemic fluorosis in the counties (cities, districts) of Henan Province, so as to ensure the quality of self-inspection.Methods:Totally 30 counties (cities, districts) with drinking water-borne endemic fluorosis in Henan Province were selected as project counties (cities, districts), using consulting and checking data, on-site investigation and review, the implementation of self-inspection projects were audited. The water improvement and the water fluorine content, and the prevalence of dental fluorosis in children aged 8-12 were investigated in villages with drinking water-borne endemic fluorosis, and the provincial-level quality assessment of the self-inspection projects was carried out.Results:A total of 99 villages with drinking water-borne endemic fluorosis in 30 counties (cities, districts) were investigated, and all 30 counties (cities, districts) completed the investigation task of self-inspection projects. A total of 99 water samples were collected, and there were 23 counties (cities, districts) with the same results of county (city, district) self-inspection and provincial-level review of water fluorine, accounting for 76.67%; a total of 5 815 children aged 8-12 were investigated, there were 18 counties (cities, districts) with the same results of county (city, district) self-inspection and provincial-level review of dental fluorosis detection rate, accounting for 60.00%.Conclusions:The self-inspection projects of control and evaluation of drinking water-borne endemic fluorosis at the county (city, district) level in Henan Province are completed well. Most of the self-inspection projects are consistent with the provincial-level review results, but the disease diagnosis ability of grass-roots professional personnel and the detection technical level of laboratory technician in some counties (cities, districts) need to be improved.

Objective:To understand the status of drinking water-borne endemic fluorosis in Henan Province, so as to provide scientific basis for improving prevention and control strategies.Methods:Ten counties (districts, referred to as counties) were selected from drinking water-borne endemic fluorosis areas of Henan Province in 2018. Three villages in each project county were selected according to the disease status of mild, moderate and severe conditions, and the operation status of water improvement projects, water fluoride content and dental fluorosis among children aged 8 to 12 years in each diseased village were monitored.Results:Totally 30 villages were surveyed, all of which were in the water improvement projects; a total of 25 water improvement projects were monitored, all of them were in normal operation, and the water fluoride exceeding standard rate was 28.00% (7/25), the qualified rate of water fluoride in the water improvement projects was 72.00% (18/25). Among them, 21 villages were in normal operation and the water fluoride in the water improvement projects met national standard. In which the detection rate of dental fluorosis among children aged 8 to 12 years was 36.71% (606/1 651), the index of dental fluorosis was 0.74, and the epidemic intensity was extremely mild. Water fluoride of water improvement projects in 9 villages exceeded the national standard, where the detection rate of dental fluorosis among children aged 8 to 12 years was 43.57% (261/599), the index of dental fluorosis was 0.78, and the epidemic intensity was extremely mild. The detection rate of dental fluorosis among children in the villages where the water fluoride of water improvement projects exceeded the national standard was higher than that in the villages where the water fluoride of water improvement projects met the national standard (χ 2=8.752, P < 0.01). Conclusions:The excessive fluorine content in the water of water improvement projects is still serious, and the epidemic is still severe. It is necessary to strengthen the scientific demonstration of the water improvement project construction and the project acceptance upon completion, so as to prevent unqualified projects from being put into use. We will carry out regular water quality monitoring and promptly rectify projects with water quality exceeding the standards.

Objective:To understand the prevention and control progress of drinking water-borne endemic fluorosis in Henan Province, to evaluate the effects of prevention and control measures, and provide a basis for adjusting prevention and control strategies.Methods:In 2019, a general survey was conducted in all registered drinking water-borne endemic fluorosis villages in Henan Province to monitor the basic conditions of water improvement, the fluoride content of drinking water and the prevalence of dental fluorosis in children aged 8-12 years. The control compliance (water fluoride content qualified and the detection rate of dental fluorosis of children ≤30%) status of the villages was analyzed, and calculate the compliance rate.Results:A total of 17 504 drinking water-borne endemic fluorosis villages were monitored, among them, 17 352 villages with water improvement and 152 villages without water improvement, with a water improvement rate of 99.1%. Among the 3 685 water improvement projects constructed, 3 448 were in normal operation, and the normal operation rate was 93.6%. There were 13 526 villages with qualified drinking water fluoride content, and the qualified rate of water fluorine was 77.3%; the actual beneficiary population was 11 011 000, and the population benefit rate was 90.1%. The qualified rate of water fluoride in the villages with and without water improvement was 77.9% (13 512/17 352) and 9.2% (14/152), respectively; the qualified rate of water fluoride in the villages with water improvement was significantly higher than that in the villages without water improvement (χ 2=400.58, P < 0.05). A total of 498 527 children of 8 to 12 years old were examined, 68 972 cases of dental fluorosis were detected, the detection rate of dental fluorosis was 13.84%, and the dental fluorosis index was 0.3. The number of villages meeting the control standard was 12 488, and the compliance rate was 71.3%. Conclusions:In Henan Province, the water improvement projects in the drinking water-borne endemic fluorosis areas have been basically implemented, and the disease has been effectively controlled. However, there is still a certain gap with the target of the "13th Five-Year Plan on National Prevention and Control of Endemic Diseases", and timely rectification is needed to ensure the effectiveness of the water improvement projects.

Objective To study the changes of transcriptome levels in a Bama minipig model of hypertrophic scar during wound healing and pressure therapy by using RNA sequencing (RNA-seq) technique. Methods The Bama minipig model was established by skin wounds from the back and pressure (3.4 kPa) was initiated at 60 days after skin injury. Total RNA was extracted from scar tissues at 0, 14, 30, 60, and 90 days after skin injury and then sequenced. The resulting sequences were mapped to porcine reference genomes and transcriptomes were reconstructed to search for differentially expressed genes (DEGs). The DEGs were further subjected to GO and KEGG analysis using bioinformatics method, while part of the genes were selected for verification using qRT-PCR. Results After preprocessing, more than 78% reads in each group were accurately aligned to the reference sequence. The DEGs identification result showed that 568 genes were differentially expressed after pressure treatment, with 289 up-regulated and 279 down-regulated. GO enrichment analysis revealed that DEGs in each group were mainly associated with extracellular matrix, tissue development and skin development. KEGG analysis showed that the DEGs in each group during wound healing were mainly enriched in extracellular matrix-receptor interactions, focal adhesion and apoptosis pathways; while the DEGs after pressure treatment were mainly enriched in PI3K-Akt and MAPK signaling pathway except the pathways mentioned. qRT-PCR showed that the expression patterns of 6 DEGs were consistent with RNA-seq analysis, confirming the reliability of RNA-seq result. Conclusions RNA-Seq analysis identified differentially expressed genes in animal model of scars during wound healing and pressure therapy, which provided experimental evidence for clinical scar treatment.

Objective: To explore the feasibility of laparoscopic treatment for incidental gallbladder cancer(IGBCA) and analyze the factors influencing prognosis. Methods: A retrospective study of 71 patients with IGBCA received laparoscopic treatment at Department of General Surgery, Peking University Third Hospital from January 2007 to December 2016 was conducted,the clinicopathological data and prognosis were analyzed. There were 18 males and 53 females,aged 23 to 81 years. They were divided into two groups based on the presence of intraluminal mass in the gallbladder. Sixty-five of the 71 patients received laparoscopic radical resection, the prognosis of them were compared with 14 patients with open radical resection. Results: Among the 71 patients,65 patients received radical resection,3 patients simple gallbaldder resection and 3 patients palliative resection. Postoperative complications occurred in 6 patients. IGBCA were detected by frozen section in 57 patients,with the accuracy of 96.5%,while the accuracy of T stage is 43.8% in the 48 patients received T stage evaluation during frozen section examination. The T stages based on final pathology were Tis(n=6),T1a(n=5),T1b(n=10),T2(n=46),and T3(n=4).The number of harvested lymph node was 4.7±2.9(range:2-12).There are 14 patients with lymph node metastasis. The 50 patients with intraluminal gallbladder mass include 21 patients with ≤T1b stage and 29 patients with ≥T2 stage, while the 21 patients without intraluminal gallbladder mass are all with ≥T2 stage. The median survival time of the 71 patients was 33 months, with the 5-year cumulative survival rate 67.3%. The 5-year cumulative survival rate is 78.5% for the 65 patients who received radical resection,comparable with those who received open radical resection(P=0.485).Univariate analysis demonstrated that T stage, lymph node metastasis, G grade, lymphovascular invasion, neural invasion, acute cholecystectomy, bile spillage, gallbladder mass and preoperative CA19-9/CEA were the most important prognostic factors(P<0.05). Conclusions Laparoscopic treatment for IGBCA is feasible, especially for those with intraluminal gallbladder mass. The accuracy of frozen section examination in evaluating T stage is low.
