Objective To observe the effect of self-assembling Atractylodes Rhizome Decoction combined with quadruple therapy on Helicobacter pylori (Hp)-positive peptic ulcer and its effect on wound healing, gastric acid secretion and recurrence.MethodsThis study was based on 70 patients with Hp-positive peptic ulcer treated in our hospital from March 2012 to May 2014.The patients were divided into study group and control group according to the order of admission.(BAO), the maximum gastric acid secretion (MAO), the peak gastric acid secretion (P<0.05).The treatment group is divided into two groups according to the treatment group.(PAO), Hp eradication and recurrence were observed and compared.ResultsAfter treatment, the total effective rate of wound healing study group was 80.00% higher than that 57.14% of the control group (χ2=4.242, P<0.05).The levels of BAO, MAO and PAO in the two groups were significantly lower than those before treatment (P<0.05).The eradication rates of Hp in the study group were significantly higher than those in the control group at 6 months and 1 year follow-up.The recurrence rate was significantly lower in the study group than in the control group (P<0.05),There was no significant difference between the two groups.ConclusionThe clinical effect of self-made Baishui Yipi Decoction combined with quadruple therapy on Hp-positive peptic ulcer patients is effective in promoting wound healing and Hp eradication, and inhibiting gastric acid secretion and reducing the recurrence rate.It is a kind of medicine worthy of clinical application Program.

Objective:To investigate the regulatory effects of tenofovir disoproxil fumarate on oxidative stress and peripheral blood Th17/Treg balance in patients with hepatitis B cirrhosis.Methods:A total of 102 patients with hepatitis B cirrhosis who received treatment in the Marine Police Corps Hospital of Chinese People's Armed Police, China from March 2020 to June 2021 were included in this study. They were randomly assigned to undergo treatment with either tenofovir disoproxil fumarate ( n = 51, observation group) or entecavir ( n = 51, control group) for 42 weeks. The levels of malondialdehyde (MDA), superoxide dismutase (SOD), nitric oxide (NO), T helper 17 cells (Th17), regulatory T cells (Treg), Th17/Treg ratio, hyaluronic acid (HA), laminin (LN), type III procollagen (PC III), type IV collagen (IV-C), hepatitis B virus DNA negative rate, HBeAg negative rate, and alanine aminotransferase normalization rate pre- and post-treatment as well as the incidence of adverse reactions were compared between the two groups. Results:Before treatment, there were no significant differences in SOD, MDA, NO, Th17, Treg, Th17/Treg ratio, HA, LN, PC III, IV-C between the two groups (all P > 0.05). After treatment, SOD and Treg in the observation group were (121.52 ± 23.52) U/L and (3.51 ± 0.70)% in the observation group, respectively, which were significantly higher than (113.30 ± 20.05) U/L and (3.14 ± 0.49)%, respectively in the control group ( t = 1.90, -4.14, both P < 0.05). MDA, NO and Th17, Th17/Treg ratio, HA, LN, PC III, and IV-C in the observation group were (7.40 ± 1.35) mmol/L, (22.56 ± 4.25) μmol/L, (1.29 ± 0.46)%, (0.45 ± 0.11), (212.52 ± 16.62) μg/L, (135.52 ± 14.02) μg/L, (132.52 ± 15.62) μg/L,(96.52 ± 10.02) μg/L, respectively, which were significantly lower compared with the control group ( t = -6.81, 4.02, 3.10, -8.46, -13.27, -15.23, -13.67, -17.38, all P < 0.05). Hepatitis B virus DNA negative rate, HBeAg negative rate, and alanine aminotransferase normalization rate in the observation group were 76.47% (39/51), 68.63% (35/51) and 74.51% (38/51), respectively, which were higher than 56.86% (29/51), 41.18% (21/51), 54.90% (28/51) in the control group ( χ2 = 4.41, 7.76, 4.29, all P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Tenofovir disoproxil fumarate is highly effective on hepatitis B cirrhosis. It can reduce oxidative stress and regulate peripheral blood Th17/Treg balance.

Objective:To investigate the value of serum gastrin 17 (G-17), pepsinogen I (PG I), pepsinogen II (PG II), and programmed cell death protein 5 (PDCD5) in the identification of gastric precancerous state and the diagnosis of early gastric cancer.Methods:A total of 86 patients with early gastric cancer who received treatment at the Marine Police Corps Hospital of Chinese People's Armed Police Force from July 2018 to June 2022 were included in the gastric cancer group. Eighty patients with gastric precancerous states who concurrently received treatment in the same hospital were included in the precancerous state group. An additional 80 partiapants who concurrently received physical examination in the same hospital were included in the healthy group.The value of G-17, PG I, PG II, and PDCD5 in the diagnosis of early gastric cancer was analyzed.Results:The levels of G-17 and PG II in the precancerous state group [(10.87 ± 3.23) pmol/L, (15.78 ± 3.33) μg/L] and gastric cancer group [(18.78 ± 4.10) pmol/L, (21.25 ± 4.48) μg/L] were significantly higher compared with the healthy group [(5.56 ± 1.43) pmol/L, (13.52 ± 3.02) μg/L, F = 362.65, 94.12, all P < 0.05]. The levels of PG I and PDCD5 in the precancerous state group [(79.52 ± 16.62) μg/L, (1.35 ± 0.15) μg/L] and gastric cancer group [(50.06 ± 15.58) μg/L, (0.85 ± 0.13) μg/L] were significantly lower than those in the healthy group [(110.12 ± 30.23) μg/L, (1.60 ± 0.12) μg/L, F = 151.07, 650.56, all P < 0.05)].There were significant differences between the precancerous state and the gastric cancer groups in terms of family history of gastric cancer, consumption of high salt fried foods, alcohol consumption history, and Helicobacter pylori (Hp) infection ( χ2 = 10.39, 4.68, 11.47, 36.49, all P < 0.05). Family history of gastric cancer ( OR = 1.42, 95% CI = 1.03-1.96) and Hp infection ( OR = 3.76, 95% CI = 1.30-10.85) were identified as risk factors for gastric cancer ( P < 0.05). The combination of G-17, PG I, PG II, and PDCD5 had the highest predictive efficiency for early gastric cancer ( P < 0.05), with the area under the receiver operating characteristic curve being 0.982, sensitivity and specificity of 98.84% and 90.00%, respectively. Conclusion:Family history of gastric cancer and Hp infection are risk factors for gastric cancer. Patients with precancerous state and early gastric cancer have elevated serum levels of G-17 and PG II and reduced serum levels of PG I and PDCD5 protein. Combined detection of these four indicators has a high diagnostic value for early gastric cancer.

Mandibular defects caused by injuries, tumors, and infections are common and can severely affect mandibular function and the patient's appearance. However, mandible reconstruction with a mandibular bionic structure remains challenging. Inspired by the process of intramembranous ossification in mandibular development, a hierarchical vascularized engineered bone consisting of angiogenesis and osteogenesis modules has been produced. Moreover, the hierarchical vascular network and bone structure generated by these hierarchical vascularized engineered bone modules match the particular anatomical structure of the mandible. The ultra-tough polyion complex has been used as the basic scaffold for hierarchical vascularized engineered bone for ensuring better reconstruction of mandible function. According to the results of in vivo experiments, the bone regenerated using hierarchical vascularized engineered bone is similar to the natural mandibular bone in terms of morphology and genomics. The sonic hedgehog signaling pathway is specifically activated in hierarchical vascularized engineered bone, indicating that the new bone in hierarchical vascularized engineered bone underwent a process of intramembranous ossification identical to that of mandible development. Thus, hierarchical vascularized engineered bone has a high potential for clinical application in mandibular defect reconstruction. Moreover, the concept based on developmental processes and bionic structures provides an effective strategy for tissue regeneration.
