ABSTRACT
Objective:To explore the clinical significance of hepatitis B virus (HBV) DNA detection in screening patients with hepatitis B.Methods:Clinical data of 682 331 hepatitis B patients were retrospectively analyzed. The HBV DNA of these patients was detected in the Fifth Medical Center of the PLA General Hospital from January 2017 to December 2021, there were 481 159 males and 201 172 females in this cohort, the average age was (41.34±16.13) years. Patients were divided into HBV DNA positive group (219 879 cases) and HBV DNA negative group (462 452 cases). Clinical characteristics, data of five serologic markers of hepatitis B and hepatitis B surface antigen quantification (HBsAg-QN), liver function, alpha fetoprotein (AFP) and prothrombin time (PT) results were collected and analyzed and compared between the two groups.Results:The positive rate of HBV DNA was 32.22% (219 879/682 331) in this cohort. Among the different age groups, the positive rate of HBV DNA was the highest (40.34%, 128 038/317 380) in young people aged 18-44 years. The proportion of patients was lower among aged <1, 45-59 and ≥60 years patients in HBV DNA positive group than that in HBV DNA negative group, while the proportion of patients was higher among aged 1-17 and 18-44 years patients in HBV DNA positive group than that in HBV DNA negative group (all P<0.001). Among 2 291 <1-year-old infants tested for HBV DNA, 71 infants were HBV DNA positive. The positive rates of HBV DNA from 2017 to 2021 were 4.86% (27/556), 3.68% (14/380), 3.47% (17/490), 1.55% (6/386) and 1.46% (7/479) respectively, showing a downward trend year by year. The positive rate of HBV DNA in acute hepatitis B (AHB) patients was the highest (49.88%, 208/417) among 680 040 patients with hepatitis B. The proportion of AHB patients (0.09%, 208/219 808) and chronic hepatitis B (80.44%, 176 806/219 808) in HBV DNA positive group was higher than that in HBV DNA negative group [0.05% (209/460 232) and 65.45% (301, 216/460 232)], while the proportion of patients with HBV-related liver cirrhosis (11.28%, 24 793/219 808), HBV-related liver cancer (6.72%, 14 775/219 808), liver cancer surgery (1.39%, 3 055/219 808) and liver transplantation (0.08%, 171/219 808) were lower than that in HBV DNA negative group [22.99% (105 813/460 232), 7.25% (33 385/460 232), 3.50% (16 129/460 232) and 0.76% (3 480/460 232)] (all P<0.001). At the same time, positive rate of hepatitis B surface antigen (HbsAg), HBsAg-QN, hepatitis B e antigen (HbeAg), level of total bilirubin, total bilirubin, AFP and PT were higher in HBV DNA positive group than those in HBV DNA negative group, while the age, male ratio and albumin results in HBV DNA positive group were lower than those in HBV DNA negative group (all P<0.01). The HBV DNA loads were higher in HBsAg positive group, hepatitis B surface antibody positive group and HBeAg positive group than those in respective negative groups, while the HBV DNA loads were lower in hepatitis B e antibody positive group and hepatitis B core antibody positive group than those in respective negative groups (all P<0.001). Conclusions:The mother to child transmission rate of<1-year-old infants decreases year by year. HBV DNA is an important factor for the progression of hepatitis B disease. HBV DNA positive hepatitis B patients with higher HBsAg-QN values are more likely to have abnormal serum markers such as liver dysfunction. HBV DNA detection is therefore of clinical importance in screening patients with hepatitis B.
ABSTRACT
Objective:To compare the clinical efficacy of endoscopic resection and laparoscopic surgery in the treatment of gastric gastrointestinal stromal tumor (GIST) with a maximum diameter of 2 to 5 cm, and to analyze the influence of factors such as tumor surface, growth pattern and lesion origin on the choice of resection method, so as to provide a safer and more effective treatment for patients with gastric GIST.Methods:From January 2012 to November 2019, at the First Affiliated Hospital of Zhengzhou University, the clinical data of 301 patients with gastric GIST who underwent endoscopic resection (137 cases in the endoscopic resection group) or laparoscopic surgery (164 cases in the laparoscopic surgery group) were retrospectively analyzed, including age, gender, whether there was depression on the tumor surface (the local subsidence depth of the mucosa on the tumor surface was >5 mm), whether the tumor surface was irregular (non-hemispherical or non-elliptical tumor surface), whether there was combined ulcer, location, shape, origin of the lesion, growth pattern (intralumina growth or combined intraluminal and extraluminal growth), risk classification (very low risk, low risk, medium risk, high risk), whether the tumor was en bloc resection, operation time, whether bleeding or not, fasting time, indwelling time of gastric tube, time of hospitalization, time of postoperative hospital stay, postoperative complications and follow-up. Independent sample t test, chi-square test or Fisher′s exact test and Wilcoxon rank sum test were used for statistical analysis. Results:Among the 137 patients with gastric GIST in the endoscopic resection group, 85 cases (62.0%) underwent endoscopic submucosal dissection, 9 cases (6.6%) underwent endoscopic submucosal excavation, 42 cases (30.7%) underwent endoscopic full-thickness resection, and 1 case (0.7%) underwent submucosal tunnel endoscopic resection. There were no significant differences in gender, age, lesion location, tumor size, and risk classification between the endoscopic resection group and the laparoscopic surgery group (all P>0.05). The tumor surface was depressed, with ulcer or irregular in 1, 49, 26, and 2 cases of patients with gastric GIST of very low risk, low risk, medium risk and high risk, respectively. There was statistically significant difference in the proportion of depression, irregularity and ulcer on the tumor surface at different risk levels ( Z=-2.55, P=0.011). The complete tumor resection rate of the endoscopic resection group was lower than that of the laparoscopic surgery group (86.1%, 118/137 vs. 100.0%, 164/164), and the difference was statistically significant ( χ2=24.28, P<0.001). However the operation time, fasting time, the indwelling time of gastric tube, time of hospitalization, and the time of postoperative hospital stay of the endoscopic resection group were shorter than those of the laparoscopic surgery group, and the total hospitalization cost was lower than that of the laparoscopic surgery group (90.0 min (62.5 min, 150.0 min) vs. 119.5 min, (80.0 min, 154.2 min); 3 d (3 d, 4 d) vs. 5 d (4 d, 7 d); 3 d (2 d, 4 d) vs. 4 d (2 d, 6 d); 11 d (10 d, 14 d) vs. 16 d (12 d, 20 d); 7 d (6 d, 9 d) vs. 9 d (7 d, 11 d); (38 211.6±10 221.0) yuan vs. (59 926.1±17 786.1) yuan), and the differences were statistically significant ( Z=-2.46, -7.12, -4.44, -6.89 and -5.92, t=-13.24; all P<0.05). The incidence of postoperative abdominal pain and other severe postoperative complications (including shock, respiratory failure, pulmonary embolism, gastroparesis, etc.) of the endoscopic resection group were all lower than those of the laparoscopic surgery group (16.8%, 23/137 vs. 27.4%, 45/164; 0.7%, 1/137 vs. 4.9%, 8/164), and the differences were statistically significant ( χ2=4.84, Fisher′s exact test, P=0.028 and 0.043). There were no significant differences in the incidence of intraoperative bleeding, postoperative bleeding, fever and perforation between the two groups (all P>0.05). The incidence of operation-related complications of lesions with intraluminal growth and originating from muscularis propria in the endoscopic resection group were lower than those of the laparoscopic surgery group (19.5%, 25/128 vs. 32.6%, 45/138; 12.6%, 12/95 vs. 31.4%, 37/118), and the differences were statistically significant ( χ2=5.86 and 10.42, P=0.016 and 0.001). There was no significant difference in the postoperative tumor recurrent rate between the endoscopic resection group and the laparoscopic surgery group (0, 0/137 vs. 2.4%, 4/164; Fisher’s exact test, P=0.129). Conclusions:Endoscopic treatment is safe and effective for gastric GIST with a maximum diameter of 2 to 5 cm, which is superior to laparoscopic surgery. However, laparoscopic surgery is recommended for tumor with depressed, ulcerative, or irregular surface and combined intraluminal and extraluminal growth.
ABSTRACT
Data of 55 cases of gastric neuroendocrine neoplasms (G-NENS) with diameter ≤12 mm in the First Affiliated Hospital of Zhengzhou University from August 2014 to August 2019 were retrospectively analyzed. According to the methods of endoscopic resection, the patients were divided into two groups: the endoscopic mucosal resection with a cap (EMR-C) group (35 cases) and the endoscopic submucosal dissection (ESD) group (20 cases). The results showed that the success rates of operation, the whole resection rates and the complete resection rates were all 100.0% in the two groups. Compared with the ESD group, the EMR-C group had a shorter median operation time (12.00 min VS 28.35 min, P<0.001), less mean hospitalization costs (21 165.19 yuan VS 28 400.35 yuan, P=0.004), and a similar overall incidence of complications [2.86% (1/35) VS 0, P=1.000]. By March 2020, the recurrence rate of EMR-C group and ESD group were 28.6% (10/35) and 15.0% (3/20), respectively, without significant difference ( P=0.418). It is suggested that for G-NENS with diameter ≤12 mm, without muscular invasion, lymph node metastasis or distant metastasis, EMR-C and ESD are both safe and effective, but EMR-C has more advantages in terms of operation time and hospitalization costs.
ABSTRACT
【Objective】 To investigate the preoperative anemia and perioperative blood transfusion in patients with duodenal papillary carcinoma who underwent Whipple surgery. 【Methods】 The clinical data of 1 959 cases with duodenal papillary carcinoma, subjected to Whipple surgery, were retrospectively analyzed. 【Results】 The rate of anemia in preoperative patients with duodenal papillary carcinoma was 54.87%(1 075/1 959). The incidence rate of anemia in the three age groups from low to high was 44.92% (≤50 years old, 190/423), 52.82% (51~64 years old, 506/958), and 65.57% (≥65 years old, 379/578) (P<0.05), and the highest rate of anemia occurred in patients aged above 65. There was a significant statistical difference among patients with different body mass index (BMI)(P<0.05). Patients with moderate or severe anemia received more red blood cells than patients with mild anemia during the perioperative period (P<0.05). The average hospitalization time of the blood transfusion patients was 27.25 days, and that of non-transfusion patients was 22.22 days (P<0.05). The amount of blood loss and hospitalization time of patients underwent laparoscopic and robotic surgery were significantly lower than those underwent open surgery patients (P <0.05). There were only 24.09%(186/772) treated with drugs for anemia intervention and the majority of patients (75.91%, 586/772) were treated with blood transfusions to interfere with anemia during hospitalization. 【Conclusion】 There are significant differences in the incidence rate of preoperative anemia among patients with duodenal papillary carcinoma who undergone Whipple surgery. Low BMI, abnormal WBC, and perioperative blood transfusion are high-risk factors for prolonged hospital stay, whereas anemia is not associated with prolonged hospital stay.

ABSTRACT
Objective:To compare the clinical efficacy of anti-reflux mucosectomy (ARMS) and endoscopic cardial constriction ligation (ECCL) on treatment of gastroesophageal reflux disease.Methods:A retrospective study was conducted on the data of 48 consecutive patients with gastroesophageal reflux disease, who underwent ARMS or ECCL at the First Affiliated Hospital of Zhengzhou University from December 2015 to August 2018. Twenty cases were in the ARMS group and 28 cases in the ECCL group. The short-term and long-term efficacies were compared between the two groups.Results:The success rate of operation was 100.0% in the both groups. The operation time of the ECCL group was significantly shorter than that of the ARMS group (8.43±1.59 min VS 34.05±12.35 min, t=-9.227, P<0.001). After 2 months follow-up, the symptom improvement rate of the ECCL group and the ARMS group was 89.3% (25/28) and 60.0% (12/20), respectively ( χ2=4.128, P=0.042). The GERD Q score of the ECCL group was significantly lower than that of the ARMS group (6.24 ±1.22 VS 7.35±1.79, t=-2.400, P=0.023). One year after operation, there were no significant differences in the symptom improvement rate, GERD Q score, DeMeester score and the time percentage of pH<4 between the two groups ( P>0.05). Conclusion:The long-term clinical effect of ARMS and ECCL is similar, but the short-term clinical effect of ECCL is superior to ARMS.
ABSTRACT
Objective To evaluate the role of spinal histone acetylation in persistent postoperative pain in rats. Methods Pathogen?free healthy male Sprague?Dawley rats, weighing 200-250 g, aged 2 months, in which intrathecal catheters were implanted at the lumbar level according to an improved method, were used in the study. Eighty?four rats, in which intrathecal catheters were successfully implanted, were divided intoⅠ-Ⅵgroups(n=14 each)using a random number table. Artificial cerebrospinal fluid 20 μl was intrathecally administered at 1, 2, 3 and 4 days before operation and 1 day after operation inⅠandⅣgroups. At 1, 2, 3 and 4 days before operation and 1 day after operation, dimethyl sulfoxide 10 μl and SAHA(50 μg∕10μl)were intrathecally injected inⅡandⅤgroups and inⅢandⅥgroups, respective?ly, followed by artificial cerebrospinal fluid(10 μl)flush after each injection. Rats underwent sham oper?ation inⅠ?Ⅲ groups. Persistent postoperative pain was evoked by skin∕muscle incision and traction in Ⅳ?Ⅵ groups. The mechanical paw withdrawal threshold(MWT)was measured at 1 day before operation(T0)and 1, 3, 7, 14 and 21 days after operation(T1?5). Four rats were sacrificed in each group after measurement of MWT at T4, and the lumbar segments(L4?6)of the spinal cord were removed for determi?nation of the expression of acetylated histone H3(Ac?H3)and Ac?H4 by Western blot. Results There was no significant difference in each index amongⅠ?Ⅲ groups(P>0.05). Compared with group Ⅰ, the MWT was significantly decreased at T2?5, and the expression of Ac?H3 and Ac?H4 was down?regulated at T4 in group Ⅳ(P<0.05). Compared with group Ⅳ, the MWT was significantly increased at T2?5, and the expression of Ac?H3 and Ac?H4 was up?regulated at T4in group Ⅵ(P<0.05). Conclusion Histone acetylation is involved in the development and maintenance of persistent postoperative pain in rats.
ABSTRACT
Objective To investigate the changes in acetylation of histone in the spinal dorsal horn in a rat model of persistent postoperative pain.Methods Ninety-six malc Sprague-Dawley rats,weighing 200-250 g,aged 6-8 weeks,were randomly divided into 2 groups (n=48 each) using a random number table:sham operation group (group S) and persistent postoperative pain group (group PPP).The rat model of persistent postoperative pain evoked by skin/muscle incision and retraction was established according to the method described by Flatters.After the rats were anesthetized with intraperitoneal chloral hydrate,the skin and superficial muscle of the medial thigh were incised and retractors inserted.This tissue was retracted for 1 h.The mechanical paw withdrawal threshold (MWT) was measured at 1 day before operation and 1,3,7,14,and 21 days after operation.Four animals were sacrificed in each group after measurement of MWT at each time point for detection of acetylated histone H3 (Ac-H3) and acetylated histone H4 (Ac-H4) expression (by Western blot analysis) and the number of Ac-H3 and Ac-H4 positive cells in the spinal cord horn (by immunofluorescence histochemistry).Results Compared with group S,the MWT was significantly decreased at 3,7,14 and 21 days after operation,the expression of Ac-H3 and Ac-H4b was significantly down-regulated at 3,7 and 14 days after operation,and the number of Ac-H3 and Ac-H4 positive cells was significantly decreased at 7,14 and 21 days after operation in group PPP (P＜0.05 or 0.01).The MWT,expression of Ac-H3 and Ac-H4b,and the number of Ac-H3 and Ac-H4 positive cells were significantly higher at 21 days after operation than at 14 days after operation in group PPP (P＜0.05).Conclusion Acetylation of histone in the spinal dorsal horn is decreased after operation,which may be involved in the development and maintenance of persistent postoperative pain in rats.

ABSTRACT
BACKGROUND:Cryopreservation of human umbilical cord mesenchymal stem cel s has been a hot research issue currently, but the studies concerning their effects on expansion of hematopoietic stem/progenitor cel s after cryopreservation are seldom. OBJECTIVE:To investigate the effects of human umbilical cord mesenchymal stem cel s before and after cryopreservation as feeder layer on expansion of human bone marrow mononuclear cel s in vitro. METHODS:2.5g/L mitomycin C processed human umbilical cord mesenchymal stem cel s and bone marrow mesenchymal stem cel s at passage 3 were used as the feeder layer to expand adult al ogeneic bone marrow mononuclear cel s in culture. Up to day 35, methylcel ulose assay was used to detect hematopoietic stem/progenitor cel colony proliferation. RESULTS AND CONCLUSION:There were no differences in the morphology and size of colonies in the cryopreserved human umbilical cord mesenchymal stem cel group, bone marrow mesenchymal stem cel group and non-cryopreserved human umbilical cord mesenchymal stem cel group. However, these parameter described above were significantly higher in these three groups than the blank control group (P<0.05). There were fewer colonies in the cryopreserved human umbilical cord mesenchymal stem cel group than the non-cryopreserved human umbilical cord mesenchymal stem cel group (P<0.05). These findings indicate that human umbilical cord mesenchymal stem cel s before and after cryopreservation have the ability as feeder layer on expansion of bone marrow mononuclear cel s in vitro similar to bone marrow mesenchymal stem cel s. But this ability of human umbilical cord mesenchymal stem cel s may decrease after cryopreservation.
