ObjectiveTo explore the characteristics of circadian rhythm of blood pressure in patients with masked hypertension （MH） and its relationship with twelve two-hour peirods， providing a basis for early detection and intervention of MH. MethodsPatients who underwent 24-hour ambulatory blood pressure examination in the ambulatory blood pressure room of Jiangsu Province Hospital of Chinese Medicine from January to December 2022 were enrolled， and according to their outpatient blood pressure measurements， 24-hour ambulatory blood pressure monitoring and follow-up survey results， the MH， essential hypertension （EH） and normal blood pressure groups were classified， with 50 cases in each group. The general data， office blood pressure and 24-hour ambulatory blood pressure monitoring data were collected. The circadian rhythm of blood pressure including 24-hour average systolic blood pressure （24h SBP）， daytime average systolic blood pressure （d SBP）， nighttime average systolic blood pressure （n SBP）， 24-hour average diastolic blood pressure （24h DBP）， daytime average diastolic blood pressure （d DBP）， and nighttime average diastolic blood pressure （n DBP） were compared among the groups， and the nighttime blood pressure dipping percentage was calculated. The type of circadian rhythm was determined based on the nighttime blood pressure dipping percentage. The variability of blood pressure including 24h SBP standard deviation （24h SBP-SD）， d SBP standard deviation （dSBP-SD）， n SBP standard deviation （nSBP-SD）， 24h DBP standard deviation （24h DBP-SD）， d DBP standard deviation （dDBP-SD）， and n DBP standard deviation （nDBP-SD） were compared among groups， and the corresponding coefficient of variation （CV）， that is， 24h SBP-CV， d SBP-CV， n SBP-CV， 24h DBP-CV， d DBP-CV and n DBP-CV， were calculated. Based on the 24-hour ambulatory blood pressure monitoring results， the twelve two-hour average SBP and DBP in each group were calculated and compared. Simultaneously， patients with EH were divided into grades 1， 2， and 3 for further stratified analysis. ResultsThe age of the MH group was significantly higher than that of the EH group and the normal blood pressure group （P＜0.01）. The body mass index （BMI） and the proportion of smoking and alcohol consumption in the MH group and the EH group were significantly higher than those in the normal blood pressure group （P＜0.05 or P＜0.01）. In the normal blood pressure group， there were 49 dipper patterns （98.0%） and one non-dipper pattern （2.0%）； in the MH group， there were two dipper patterns （4.0%）， 29 non-dipper patterns （58.0%） and 19 reverse-dipper patterns （38.0%）； in the EH group， there were 20 dipper patterns （40.0%）， 23 non-dipper patterns （46.0%） and seven reverse-dipper patterns （14.0%）. Compared to the normal blood pressure group， the groups of MH and EH had significantly decreased proportion of dipper pattern and increased proportion of non-dipper and reverse-dipper pattern （P＜0.01）； the proportion of dipper pattern in the MH group was lower than that in the EH group， while the proportion of reverse-dipper pattern was higher （P＜0.01）. Compared to those in the normal blood pressure group， n SBP and n DBP in the MH group， as well as the the average SBP and average DBP at Zi hour （子时， 23：00-1：00）， Chou hour （丑时， 1：00-3：00）， Yin hour （寅时， 3：00-5：00）， Mao hour （卯时， 5：00-7：00） and average SBP at Hai hour （亥时， 21：00-23：00） in the MH group increased，while the average DBP at Si hour （巳时， 9：00-11：00） decreased （P＜0.01）； 24h SBP， 24h DBP， d SBP， d DBP， n SBP， and n DBP，d SBP-SD， n SBP-SD，n DBP-SD increased， as well as the average SBP and average DBP at twelve two-hour periods increased in the EH group，while the 24h SBP-CV， 24h DBP-CV，and d DBP-CV in the EH group decreased（P＜0.05 or P＜0.01）. The EH group had higher 24h SBP， 24h DBP， d SBP， d DBP， n SBP， n DBP， 24h DBP-SD and n DBP-SD ， as well as higher average SBP and DBP at all twelve two-hour periods， and lower d DBP-CV than the MH group（P＜0.05 or P＜0.01）. The EH group had 18 cases of grade 1 （36.0％）， 19 cases of grade 2 （38.0％） and 13 cases of grade 3 （26.0％）， with no significant differences among groups （P＞0.05）. ConclusionThe circadian rhythm of blood pressure in MH patients are mostly non-dipper and reverse-dipper patterns， and the abnormal elevation of blood pressure is obvious at Zi hour， Chou hour， Yin hour and Mao hour （23：00-7：00）.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

OBJECTIVE: To investigate the clinical efficacy of percutaneous screw fixation combined with minimally invasive transpedicular bone grafting and non-bone grafting in the treatment of thoracolumbar fractures. METHODS: From Janury 2021 to June 2022, 40 patients with thoracolumbar fracture were divided into the experimental group and the control group. There were 26 patients in the experimental group, including 21 males and 5 females with an aberage age of (47.3±12.3) years old, who underwent percutaneous pedicle screw fixation combined with transpedicular autogenous bone grafting. In the control group, 14 patients received percutaneous pedicle screw fixation only. including 7 makes and 7 females with an average age of (50.2±11.2) years old. The operative time, intraoperative blood loss, anterior height ratio of injured vertebrae, Cobb angle, visual analogue score (VAS), MacNab scores, loosening or broken of the implants. were compared and analyzed. RESULTS: There was no significant difference in operation time, intraoperative blood loss, VAS and anterior height ratio of injured vertebrae between the two groups. Compared with the preoperative results, VAS and anterior height ratio of injured vertebrae were improved statistically(P<0.05). For Cobb angle of injured vertebra, there was no significant difference between the two groups before surgery (P=0.766). While at 1 week, 3 months and 12 months after surgery, there were statistically differences between the two groups (P values were 0.042, 0.007 and 0.039, respectively). The Cobb angle of injured vertebrae one year after operation was statistically decreased in both groups compared with that before surgery (P<0.001). One year after surgery, the excellent and good rate of Macnab scores was 96.15% in the experimental group and 92.86% in the control group, and there was no statistical differences between the two groups (P=0.648). There was one patient in the control group suffering superficial wound infection on the third day, which was cured by dressing change and anti-infection treatment. There were no postoperative screw loosening and broken in both groups. CONCLUSION The two surgical methods have the advantages of less trauma, less pain and quicker recovery, which can restore the height of the injured vertebra, reconstruct the spinal sequence and reduce the fracture of the vertebral body. Transpedicular autogenous bone grafting can increase the stability of the fractured vertebra and maintain the height of the vertebra better after surgery, thus reducing the possibility of complications such as kyphosis, screw loosening and broken.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

Objective: To investigate the safety and efficacy of pelvic peritoneal reconstruction and its effect on anal function in laparoscopy-assisted anterior resection of low and middle rectal cancer. Methods: A prospective cohort study was conducted. Consecutive patients with low and middle rectal cancer who underwent laparoscopy-assisted transabdominal anterior resection at Naval Military Medical University Changhai Hospital from February 2020 to February 2021 were enrolled. Inclusion criteria: (1) the distance from tumor to the anal verge ≤10 cm; (2) laparoscopy-assisted transabdominal anterior resection of rectal cancer; (3) complete clinical data; (4) rectal adenocarcinoma diagnosed by postoperative pathology. Exclusion criteria: (1) emergency surgery; (2) patients with a history of anal dysfunction or anal surgery; (3) preoperative diagnosis of distant (liver, lung) metastasis; (4) intestinal obstruction; (5) conversion to open surgery for various reasons. The pelvic floor was reconstructed using SXMD1B405 (Stratafix helical PGA-PCL, Ethicon). The first needle was sutured from the left anterior wall of the neorectum to the right. Insertion of the needle was continued to suture the root of the sigmoid mesentery while the Hemo-lok was used to fix the suture. The second needle was started from the beginning of the first needle, after 3-4 needles, a drainage tube was inserted through the left lower abdominal trocar to the presacral space. Then, the left peritoneal incision of the descending colon was sutured, after which Hemo-lok fixation was performed. The operative time, perioperative complications, postoperative Wexner anal function score and low anterior resection syndrome (LARS) score were compared between the study group and the control group. Three to six months after the operation, pelvic MRI was performed to observe and compare the pelvic floor anatomical structure of the two groups. Results: A total of 230 patients were enrolled, including 58 who underwent pelvic floor peritoneum reconstruction as the study group and 172 who did not undergo pelvic floor peritoneum reconstruction as the control group. There were no significant differences in general data between the two groups (all P>0.05). The operation time of the study group was longer than that of control group [(177.5±33.0) minutes vs. (148.7±45.5) minutes, P<0.001]. There was no significant difference in the incidence of perioperative complications (including anastomotic leakage, anastomotic bleeding, postoperative pneumonia, urinary tract infection, deep vein thrombosis, and intestinal obstruction) between the two groups (all P>0.05). Eight cases had anastomotic leakage, of whom 2 cases (3.4%) in the study group were discharged after conservative treatment, 5 cases (2.9%) of other 6 cases (3.5%) in the control group were discharged after the secondary surgical treatment. The Wexner score and LARS score were 3.1±2.8 and 23.0 (16.0-28.0) in the study group, which were lower than those in the control group [4.7±3.4 and 27.0 (18.0-32.0)], and the differences were statistically significant (t=-3.018, P=0.003 and Z=-2.257, P=0.024). Severe LARS was 16.5% (7/45) in study group and 35.5% (50/141) in control group, and the difference was no significant differences (Z=4.373, P=0.373). Pelvic MRI examination 3 to 6 months after surgery showed that the incidence of intestinal accumulation in the pelvic floor was 9.1% (3/33) in study group and 46.4% (64/138) in control group (χ(2)=15.537, P<0.001). Conclusion: Pelvic peritoneal reconstruction using stratafix in laparoscopic anterior resection of middle and low rectal cancer is safe and feasible, which may reduce the probability of the secondary operation in patients with anastomotic leakage and significantly improve postoperative anal function.

Objective: To investigate the safety, feasibility and short-term efficacy of total laparoscopic loop ileostomy reversal in patients after resection of rectal cancer. Methods: The clinical data of 20 patients who underwent total laparoscopic loop ileoscopic loop ileostomy after radical resection of rectal cancer at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, or Beijing Chaoyang District Sanhuan Cancer Hospital from October 2019 to June 2020 were collected and retrospectively analyzed. Results: All patients had successfully underwent total laparoscopic ileostomy reversal without conversion to open surgery or discontinued operation. No perioperative related death cases were found. In the whole group, the median operation time was 97 (60-145) minutes and the median intraoperative blood loss was 20 (10-100) milliliters. The median Visual Analogue Scale (VAS) score was 1.9 (1-5) one day after the operation. Nobody needed to use additional analgesic drugs. The median time to grand activities was 25 (16-42) hours, the median time to flatus was 44 (19-51) hours, and the median hospitalization after operation was 6.9 (5-9) days. No patients underwent operation related complications such as operative incision infection, abdominal and pelvic infection, intestinal obstruction, anastomotic leakage, bleeding and so on. Conclusions: Total laparoscopic loop ileostomy reversal appears to be safe, feasible and with promising efficacy for selected patients.

Aim To investigate the effectiveness and safety of alfentanil in general anesthesia.Methods In this study, a multicenter randomized double-blind con¬trolled study was conducted.A total of 352 subjects were selected and randomly assigned to fentanyl group (group A, n =176) and alfentanil group (group 15, n = 176).Anesthesia induction: intravenous midazolam 0.03 mg • kg-1 + fentanyl 25 p.g • kg"'(group A) or alfentanil 4 p,g • kg-1 ( group 15) + propofol 2 mg • kg"1 + rocuronium 0.8 mg • kg"1.Sevoflurane + fent¬anyl ( group A ) or alfentanil ( group B ) + rocuronium were used for anesthesia.The vital signs of patients re¬covery time and extuhation time, anesthesia-related complications and the use of related remedial drugs during anesthesia induction and maintenance were compared between the two groups.Results During the induction and maintenance period of anesthesia, alfentanil and fentanyl could equally effectively inhibit the stress response induced by endotracheal intubation and surgical stimulation.Alfentanil also showed more effective inhibition on stress response induced by endo¬tracheal intubation and surgical stimulation than that of fentanyl ( P < 0.05 ) .However, there was no signifi¬cant difference in the incidence of intraoperative hypo¬tension and hypertension and the time of anesthesia re¬covery and extubation between the two groups.Conclu¬sions Both alfentanil and fentanyl can effectively in¬hibit the stress response induced by surgical stimulation and could be safely used in general anesthesia in sur¬gery.Alfentanil has more advantages in maintaining the stability of blood pressure and heart rate during an¬esthesia induction and maintenance.

Sesquiterpene pyridine alkaloids are important components in Tripterygium plants, possessing a wide range of pharmacological activities, such as anti-inflammation immunosuppression, anti-tumor, anti-virus, and deinsectization, and are of great research value. They are composed of highly oxidized dihydro-β-furansquiterpene and pyridine dicarboxylic acid through ester bonds. According to the structural characteristics of pyridine dicarboxylic acid fragments, they can be divided into various structural subtypes. Up to now, more than 110 sesquiterpene pyridine alkaloids have been isolated and identified from Tripterygium plants. This study reviewed the structural features and spectral(i.e., UV, IR, MS, and NMR) characteristics of sesquiterpene pyridine alkaloids and summarized the structural elucidation process in detail to provide references for their further research and development.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.
