Objective To explore the clinical efficacy of anti-helicobacter pylori (HP) treatment on patients with type 2 diabetes mellitus and HP infection.Methods A total of 112 type 2 Diabetes patients were diagnosed with HP infection in Combine Traditional Chinese and Western Medicine Hospital of Taizhou from April 2012 to June 2016.These patients were divided into control and treatment group based on the preprandial blood glucose averages from lower to higher hierarchy.Thus,there were 56 patients in each of the two groups.The control group was given Motilium and Talcid for gastric symptoms in addition to anti-diabetes treatment,while the treatment was administered the same treatments as well as the quadruple anti-HP therapy (omeprazole,amoxicillin,clarithromycin and colloidal-bismuth-subcitrate,with Talcid stopped while colloidal-bismuth-subcitrate was administered).The anti-HP lasted for 14 days.The two groups were compared the gastric symptoms,the blood glucose levels,and the HbA1c one month after treatment.Half a year and one year post treatment,the two groups were compared the gastric mucus signs under gastroscopy.Results The improvement rates after treatment with the treatment group in abdominal pain,bloating,regurgitation,belching and diarrhea/constipation were 88.5％ (23/26),83.3％ (25/30),74.1％ (20/27),83.9％ (26/31),82.6％ (19/23),respectively,and with the control group being 29.2％(7/24),32.1％(9/28),28％(7/25),30.3％(10/33),18.2％ (4/22),respectively.The differences between the two groups were significant (x2=8.06,6.62,3.92,7.65,6.66,P＜0.05 or P＜0.01).The control group did not show significant changes in preprandial glucose levels,the glucose levels two hours post meals and the HbA1c(P＞0.05) while the treatment group showed statistically significant changes(P＜0.05 or P＜0.01).The differences in the three indicators after treatment between the two groups were significant (t =4.07,7.85,4.16,P＜ 0.05).The Gastric mucus signs under gastroscopy showed improvements in both groups after treatment.The improvement rates with the treatment group were 86.2％(25/29),86.7％ (13/15),77.8％ (14/18),72.7％ (8/11) respectively,with the control group being 36％ (9/16),27.3％ (3/11),13.3％ (2/15),14.3％ (1/7),respectively.The differences between the two groups were significant (x2 =6.71,4.12,4.38,3.85,P ＜ 0.05 or P＜ 0.01).The effectiveness rate,which was based on combined improvements in gastric symptoms,glucose levels and gastric mucus signs,was 76.8％ with the treatment group and 32.1％ with the control group.The difference was statistically significant (x2 =6.78,P＜0.01).Conclusion Anti-HP treatment can relieve the gastric symptoms,stabilize the glucose levels,and help to reverse the changed gastric mucus.All these can reduce the complications of the diabetes and improve the prognosis of the patients.

Objective To investigate the protective effects of intra-peritoneal fluid resuscitation on small intestinal mucosa in rats with hemorrhagic shock. Method Fifty Sprague-Dawley (SD) rats were randomly (random number) divided into five groups, namely sham operation group (group I ), hemorrhagic shock group (group Ⅱ ), intra-venous fluid resuscitation group (group Ⅲ ) . intravenous fluid resuscitation plus intra-peritoneal saline resuscitation (group Ⅳ ) and intravenous fluid resuscitation plus intra-peritoneal PD-2 solution resuscitation group (group Ⅴ ). The rats of 5 groups were processed with cannulations of right common carotid artery, right femoral vein and left femoral artery with systemic heparinization. The rat models of hemorrhagic shock were established with modified Wigger' s method by which the blood exsanguinated from left femoral artery. The rats of group Ⅲ were resuscitated with shed blood plus twice equal volume of Ringer's solution after modeling of hemorrhagic shock.The rats of group Ⅳ and group Ⅴ were administered intra-peritoneally with 30 mL saline and 30 mL of 2.5% PD-2 solution, respectively as adjuncts to those used in the group Ⅲ . The specimens of blood and small intestine of rats of all groups were collected 60-120 minutes after modeling and resuscitation. The activity of plasma diamine oxidase (DAO) was determined with chromatometry, the level of plasma D-lactic acid (D-LA) with spectorophotometry and the level of plasma lipopolysaccharide (LPS) with nephelometry. The histopathological and ultrastructure changes of small intestine tissue of rats were observed under light microscope and electronic microscope. Results There were remarkable differences in activity of DAO, and the levels of D-LA and IPS in rats between those ingroup Ⅱ and group I (P <0.01), and between those in group V and groups Ⅱ , Ⅲ or Ⅳ (P <0.05 or P < 0.01) The pathomorphology and ultra-structure of small intestine tissues were severely damaged in group Ⅱ compared with those in group Ⅰ , and those markedly lessened in group V compared with groups Ⅱ , Ⅲ and Ⅳ . Conclusions Intraperitoneal fluid resuscitation with PD-2 solution can significantly protect the integrity of intestinal mucosa and the normal permeability of intestinal wall, and blunts the histopathological changes, and restrains bacterial translocation from gut and reduces the level of plasma endotoxin.

Objective:To explore the distribution and hematological characteristics of rare thalassemia-associated mutations in Chenzhou region of Hunan Province with an aim to provide a basis for genetic counseling and effective prevention.Methods:A total of 37 370 individuals enrolled from January 2015 to December 2021 were screened by routine blood test and hemoglobin electrophoresis. The genotypes were determined with high-throughput sequencing.Results:A total of 8 455 thalassemia mutations (including 185 rare ones) were detected, which had involved 27 mutational types. Rare type α-Thalassemia --THAI and CD31 (AGG>AAG) have the typical microcytic hypochromic hematological features, whilst SEA-HPFH, CD14 (CTG>-TG), CD37 (TGG>TAG), -90(C>T), Codon 15 (G>A), IVS-Ⅰ-128 (T>G), CD86 (GCC>GC-) and Chinese Gγ+ (Aγδβ)0 had typical microcytic hypochromic and β-thalassemia-associated hematological features of elevated HbA2 or HbF. In addition, the -50(G>A)heterozygotes of β-thalassemia had normal or slightly decreased MCV and MCH without an increase in HbA2.Conclusion:Various forms of thalassemia-associated mutations have been identified in the Chenzhou region of Hunan Province. Above finding has facilitated development of preventive and control strategies for thalassemia as well as birth health programs.
