This consensus provides a comprehensive overview of hair transplantation, covering preoperative preparation, surgical procedures, intraoperative coordination, postoperative management, and complication prevention and treatment. It serves as a key reference and guide for implementing standardized perioperative nursing care in FUE hair transplantation.

Objective:This study aims to explore the prevalence of hepatitis E virus (HEV) infection in patients and the screening value of serological indicators for HEV infection patients.Methods:Retrospective analysis was conducted on 97 440 cases of anti-HEV IgM and IgG simultaneously tested in two Beijing hospitals from January 1, 2018 to August 31, 2023. Among them, there were 61 005 males and 36 435 females, with an average age of 51.65±13.05 years old. According to the positivity of anti HEV specific antibodies, they were divided into anti-HEV IgM positive group (3 588 cases), anti-HEV IgG positive group (18 083 cases), and anti-HEV antibody negative group (78 892 cases). Results of HEV RNA, liver function, AFP, PIVKA-Ⅱ and PT were collected, and their basic clinical information were recorded. The prevalence of HEV infection in patients, as well as the relationship between the positivity of anti-HEV specific antibodies and the patient′s age group, HEV RNA, and clinical characteristics were analyzed.Results:Among 97 440 patients who tested anti-HEV IgM and IgG simultaneously, the positivity rate of anti-HEV IgM was 3.68% (3 588/97 440), and was 18.56% for anti-HEV IgG (18 083/97 440). The overall positivity rates of anti-HEV IgM in two Beijing hospitals from 2018 to 2023 were 2.51%, 2.53%, 3.02%, 4.59%, 5.72%, and 4.26% ( χ2=1 401.73, P<0.001), while the positivity rates of anti-HEV IgG were 12.56%, 12.32%, 12.85%, 22.65%, 27.42%, and 26.66% ( χ2=1 058.29, P<0.001). These rates showed a gradual increase until 2023 when a decline was observed. The positivity rates of anti-HEV IgM (2.28%, 3.60%, 4.47%) ( χ2=89.62, P<0.001) and IgG (4.71%, 17.86%, 25.94%) ( χ2=2 017.32, P<0.001) increased with age in patients who aged 1-30, >30-60, and over 60 years old. The age and ALB values of patients in the anti-HEV IgM positive group were lower than the IgG-positive group, while the proportion of males, TBIL, ALT, AFP and PT values were higher than the IgG-positive group, and the differences were statistically significance ( P<0.05). Furthermore, patients in both the anti-HEV IgM and IgG positive groups had higher age, male proportion, TBIL, ALT, AFP, PIVKA-Ⅱ, and PT values than the anti-HEV negative group. Additionally, both groups had lower ALB values than the anti-HEV negative group, all of which were statistically significant ( P<0.05). 2 162 HEV infected patients were grouped based on HEV RNA positivity. The proportion of anti-HEV IgM single positive, IgG single positive, IgM+IgG double positive, and antibody negative patients in the HEV RNA positive group were 5.42% (18/332), 3.62% (12/332), 90.36% (300/332), and 0.60% (2/332), respectively. Among them, the proportion of anti-HEV IgM+IgG double positive patients in the HEV RNA positive group was higher than that in the HEV RNA negative group ( χ2=302.87, P<0.001), while the proportion of anti-HEV IgG single positive ( χ2=174.36, P<0.001) and anti-HEV antibody negative patients ( χ2=59.28, P<0.001) were lower than that in the HEV RNA negative group, both of which were statistically significant ( P<0.001). In addition, the positive rates of HEV RNA in anti-HEV IgM positive, IgG positive, and antibody negative patients were 29.23% (318/1 088), 17.59% (312/1 774), and 0.65% (2/306), respectively. Conclusion:The HEV infection rate among patients declined in 2023. HEV infection is age-related, with older individuals being more susceptible. Abnormal liver function and jaundice were commonly observed during HEV infection. It is crucial to note that the absence of anti-HEV specific antibodies cannot rule out HEV infection; therefore, additional testing for HEV RNA and/or HEV Ag is necessary for accurate diagnosis.

Objective:To investigate the expression of complement C3 in serums and tissues of lung adenocarcinoma patients with brain metastases and the mechanism of complement C3 in inducing epithelial mesenchymal transition (EMT).Methods:The retrospective case-control study, cell experiments and animal experiments were conducted. The serum samples from 20 healthy examinees, 20 advanced lung adenocarcinoma patients without brain metastases and 20 advanced lung adenocarcinoma patients with brain metastases at the First People's Hospital of Yancheng from January 2021 to January 2023 were collected, and the expression of complement C3 in serum samples was detected by immunoturbidimetry. At the same time, lung tissue samples were collected from 10 lung adenocarcinoma patients without brain metastases, and lung tissue and brain tissue samples were collected from 10 lung adenocarcinoma patients with brain metastases in the First People's Hospital of Yancheng. Immunohistochemistry was used to detect the expression of complement C3, C3aR, Kruppel like factor 5 (KLF5), and N-cadherin (N-cad) in the tissue samples. Using lentivirus to construct a human lung adenocarcinoma with brain metastases cell line PC14-C3 with stable overexpression of complement C3, with cells infected with empty vector virus as the control group (PC14-Ctrl). Western blotting was used to detect the expression of complement C3, KLF5, N-cad, and E-cadherin (E-cad) in PC14-C3 and PC14-Ctrl cells, and scratch assay was used to assess cell migration ability. Using the random number table method, 12 BALB/c nude mice were evenly divided into PC14-C3 group and PC14-Ctrl group. PC14-C3 cells and PC14-Ctrl cells were subcutaneously inoculated on the ventral side, and the body mass and tumor volume of the nude mice were recorded. Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of KLF5, N-cad and E-cad mRNA in various tumor cells and tumor tissues of nude mice.Results:The serum complement C3 levels in healthy individuals, lung adenocarcinoma patients without brain metastases and lung adenocarcinoma patients with brain metastases were (1.14±0.17) g/L, (1.20±0.15) g/L and (1.61±0.21) g/L, respectively. The serum complement C3 level in lung adenocarcinoma patients with brain metastases was higher than that in lung adenocarcinoma patients without brain metastases and healthy individuals, and the differences were statistically significant (both P < 0.001). The results of immunohistochemical testing showed that the proportions of positive expression areas of complement C3, C3aR, KLF5, and N-cad proteins in the lung primary lesions of lung adenocarcinoma patients with brain metastases were higher than those of patients without brain metastases, and the differences were statistically significant (all P < 0.05). The mRNA ( P < 0.05) and protein expression levels of complement C3 in PC14-C3 cells were higher than those in PC14-Ctrl cells, indicating successful transfection. The scratch assay results showed that the migration rate of PC14-Ctrl cells was (37.5±4.1)%, and the migration rate of PC14-C3 cells was (60.4±2.9)%, and the difference was statistically significant ( t = 7.86, P < 0.01). The relative expressions of EMT promoting molecules KLF5 and N-cad mRNA in PC14-C3 cells were higher than those in PC14-Ctrl cells, while the relative expression of EMT inhibiting molecule E-Cad mRNA was lower than that in PC14-Ctrl cells, and the differences were statistically significant (all P < 0.05). On the 26th day of tumor loading, the tumor volume of nude mice in PC14-C3 group was (610±10) mm 3, while that of PC14-Ctrl group was (321±30) mm 3; the body mass of nude mice in PC14-C3 group was lower than that in PC14-Ctrl group [(21.6±0.6) g vs. (23.2±0.6) g], and the differences were statistically significant (both P < 0.05). At the end of the experiment, 5 nude mice died and 1 survived in the PC14-C3 group; 1 nude mouse died and 5 survived in the PC14-Ctrl group. The relative expressions of KLF5 and N-cad mRNA in the tumor tissues of nude mice in PC14-C3 group were higher than those in PC14-Ctrl group, while the relative expression of E-Cad mRNA was lower than that in PC14-Ctrl group, and the differences were statistically significant (all P < 0.05). Conclusions:Lung adenocarcinoma patients with brain metastases have high levels of complement C3 in their serums and primary lesions. Complement C3 may induce EMT and promote the occurrence of lung adenocarcinoma brain metastases by affecting the expressions of KLF5, N-cad and E-cad.

Objective:To compare clinical outcomes of arthroscopic double-row anchor suture bridge fixation versus open reduction and internal plating in the treatment of simple humeral fracture of the greater tuberosity.Methods:From March 2013 to March 2017 at Department of Orthopaedics, Jianhu Hospital Affiliated to Nantong University, 40 patients were treated for simple humeral fracture of the greater tuberosity. They were 23 men and 17 women, aged from 25 to 70 years (mean, 53.2 years). All the fracture displacements were larger than 5 mm and the fracture blocks smaller than 3 cm × 3 cm. They were complicated with no other injuries like rotator cuff tear, superior labrum anterior posterior (SLAP) injury or Bankart injury. Of them, 18 were treated by arthroscopic double-row anchor suture bridge fixation and 22 by open reduction and internal plating. The 2 groups were compared postoperatively in terms of joint activity, visual analogue scale (VAS) pain score, American Shoulder and Elbow Surgeon (ASES) score at the last follow-up.Results:There were no significant differences in the preoperative general data between the 2 groups ( P>0.05), indicating they were comparable. The arthroscopy and open reduction groups were followed up for an average of 19 and 20 months, respectively. All the patients obtained bony union within 3 months after surgery. At the last follow-up for the arthroscopy and open reduction groups, respectively, the shoulder flexion was 152.7°±13.3° and 137.7°±19.2°, the abduction 146.0°±16.4° and 132.4°±20.5°, the VAS score 0.8±0.4 and 1.3±0.6 and the ASES score 91.8±4.1 and 87.4±5.8, showing significant differences in the above items between the 2 groups ( P<0.05). In the open reduction group, 2 patients developed subacromial impingement syndrome which was relieved after removal of the plate following fracture union. Shoulder stiffness was observed in one case but improved after manipulative release under anesthesia. Conclusion:In the treatment of simple humeral fracture of the greater tuberosity, arthroscopic double-row anchor suture fixation has advantages over open reduction and internal plating because it can lead to less invasion, quicker recovery and better functional recovery of the shoulder after operation.

Objective:To identify the association of sex hormone and sex hormone-binding globulin (SHBG) levels in patients with Graves′ disease.Methods:Between December 2017 and July 2019, 152 patients with Graves′ disease were enrolled in the Department of Endocrinology and Metabolism of Zhongshan Hospital, Fudan University. Parameters such as height, weight, thyroid function, sex hormone, fasting blood glucose, insulin, C-peptide, glycosylated albumin, HbA 1C, and liver function were collected. The associations between SHBG and bioclinical characteristics were analyzed. Results:The glycosylated albumin level was negatively associated with SHBG in all subjects ( β=-0.308, P<0.01), while this association was not significant after the adjustment for thyroid hormones. Male patients had significantly lower SHBG level than female patients ( P<0.01). In male patients, SHBG was associated with luteinizing hormone ( r=0.465, P<0.01), estradiol ( r=0.629, P<0.01), testosterone ( r=0.786, P<0.01). While in female patients, SHBG was also associated with testosterone ( r=0.191, P<0.05). In multivariate linear regression analysis, estradiol was independently associated with SHBG ( β=0.329, P<0.01) in male subjects. Conclusion:The hypogonadism and infertility in Graves′ disease patients could partially be attributed to the association between SHBG and Graves′ disease.

Thus, the fundamental question of the achievements above is how to construct a large population- based cohort in a standardized way. The Chinese Preventive Medicine Association coordinated experienced researchers from Zhejiang Provincial Center for Disease Control and Prevention and other professional institutes to write up the group standard entitled Technical specification of long-term follow-up for end point in large population-based cohort study (T/CPMA 002-2019). The standard is drafted with principles of emphasizing the scientific, normative, applicability, and feasible nature. This group standard recommended the follow-up target population, time, content, methods, quality control, and indicators assessment. The standard aims to guide the large population-based cohorts that have been or intended to be established in China, including national cohorts, regional population cohorts, and special population cohorts, hence, to improve domestic scientific research level and the international influence, and to support decision-making and practice of disease prevention and control.

Objective: Researching the influence on patients with different eating ways after the operation of mandibular angle osteotomy of inside oral cavity. Method: By using the method of convenience sampling, 50 patients were chosen who had operation of mandibular angle osteotomy of inside oral cavity in orthopedic surgery department of our hospital from January 2017 to December 2017 and the number was arranged according to the order of hospitalization. Patients with singular member were divided into the month feeding group (liquid diet were fed with the injection syringe which linked leather hose of 4-5cm after 6 hours awakening after general anesthesia in operation); patients with even number were divided into the nasal feeding group (stomach tube was put in the operation and nasal feeding was provided after 6 hours awakening after general anesthesia in operation and 5 hours after the operation). In every group, there were 25 patients. Observation scale which was made by themselves was used to evaluate the patients in the two groups and comparison for difference was made in the two groups, including weight change, wound drainage amount, oral wound secretion, the aspects of choke and cough, and the comfortable sensation of eating. Results: For weight, in nasal feeding group, (2.19±0.48) kg were reduced and in month feeding group, (5.78±0.58) kg were reduced; the difference had the statistical significance (t=23.870, P<0.05). For wound drainage amount, in nasal feeding group, the number was(38.00±11.00)ml and in month feeding group, the number was (65.00±13.00) ml, the difference was statistically significant (t=7.927, P<0.01). In the aspects of choke and cough, and wound secreta in oral cavity, in nasal feeding group, the number were 16% (4/25) and 44% (11/25) respectively which was superior to the month feeding group with the number of 44% (11/25) and 76% (19/25), the difference had the statistical significance (χ²=4.667, 5.333, P<0.05). For the comfortable sensation of eating, in the two groups, there was no significant statistical difference (χ²=0.764, P>0.05). Conclusion The nasal feeding way can improve recovery level for patients after the operation of mandibular angle osteotomy of inside oral cavity and it is worthy of promotion in clinic application.

Objective: To explore the effects of transcutaneous electrical acupoint stimulation (TEAS) on pain of patients in expansion process of skin soft tissue dilator on forehead by water injection. Methods: From June 2016 to June 2017, 100 patients in expansion process of skin soft tissue dilator on forehead by water injection meeting the inclusion criteria were admitted to Outpatient Department of Orthopedic Surgery of Shanghai Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine. There were 43 men and 57 women among the patients, aged 27 to 55 years, and the prospective randomized controlled study was performed on them. The patients were divided into TEAS nursing group and routine nursing group according to the random number table, with 50 patients in each group. Patients in routine nursing group were performed with routine nursing in every water injection in outpatient department and 2 days later. On the basis of routine nursing, patients in TEAS nursing group were performed with TEAS treatment by responsible nurses in each water injection in outpatient department. The Shangxing, Diwei, and Hegu points were positioned accurately, and electrical stimulation was performed on the 3 points simultaneously by pulse acupuncture treatment instrument, with 30 minutes each time. Two days after every water injection of outpatient department, TEAS nursing was performed at home by patients and their family members under remote guidance of the responsible nurses, with 2 times each day and 30 minutes each time. Besides, follow-up was done by phone by the responsible nurses everyday. The nursing of patients in the 2 groups lasted the whole expansion process. After the expansion process, the overall pain degree and the most severe pain degree of patients during expansion process were scored by numerical rating scale, and the overall comfort degree and its dimensions of patients during expansion process were scored by the responsible nurses every day by simplified Comfort Status Scale. Data were processed with independent sample t test and chi-square test. Results: During expansion process, the overall pain score degree and the most severe pain degree score of patients in TEAS nursing group were (5.4±1.2) and (6.5±1.0) points, which were significantly lower than (6.1±1.3) and (7.5±1.4) points of patients in routine nursing group (t=-2.62, -4.00, P<0.05 or P<0.01). During expansion process, the physiological dimension, sociocultural dimension, psychological spirit dimension, environmental dimension, and total score of the overall comfort degree of patients in TEAS nursing group were (9.6±2.9), (20.1±2.8), (29.1±1.9), (22±3), and (80±6) points, significantly higher than (5.7±2.1), (16.8±2.8), (26.0±2.8), (21±4), and (69±8) points of patients in routine nursing group (t=8.03, 6.35, 7.60, 2.11, 10.64, P<0.05 or P<0.01). Conclusions TEAS with appropriate intensity, frequency, and duration can alleviate the pain of patients during expansion process of skin soft tissue dilator on forehead by water injection and improve their comfort degree.
