Journal of Chinese Physician 2001;0(08):-
Objective To study the pathogenic molecular mechanism of H.pylori through analyzing its effect of on MMP-9 expression. Methods BGC-823 cells were cocultured with ATCC49503(CagA +)and HP 030811 (CagA -) H.pylori strains respectively, then the total cellelar RNA was extracted. The MMP-9 mRNA expression in BGC-823 cells, 9 cases of H.pylori-positive and 9 cases of H.pylori-negative gastric ulcer biopsy tissues was detected by RT-PCR. The MMP-9 protein expression on the paraffin-imbedded tissue sections of 17 cases of H.pylori-positive and 14 cases of H.pylori-negative gastric ulcer tissues was detected with immunohistochemical technique, and was quantified by image quantitative analysis. Results H.pylori induced MMP-9 expression in BGC-823, and the level of MMP-9 expression induced by CagA -postive H.pylori strain was higher than that by CagA -negative one. MMP-9 expression level was higher in the H.pylori-positive gastric ulcer tissues than that in the H.pylori-negative ones. Conclusion H.pylori-induced MMP-9 expression may play an important role in gastric ulcer formation and gastric carcinogenesis.

China Medical Equipment 2016;13(7):84-86,87
Objective: To analyze the effect of single-hole thoracoscopic surgical treatment on elderly spontaneous pneumothorax patients’ postoperative assessment and serological markers and explore single-hole thoracoscopic surgery application. Methods:78 cases of elderly patients with spontaneous pneumothorax were retrospectively analyzed, and divided into single-hole thoracoscopy group with 35 patients and conventional thoracoscopic group with 43 patients. Then the surgery indicators, postoperative pain scores and perioperative serum target level differences were compared between the two groups. Results: The operative time, postoperative drainage time and total hospital stays of single-hole thoracoscopic surgery patients were shorter than that of conventional thoracoscopic group. The differences were statistically significant (t=7.183, t=5.294, t=6.938;P<0.05). The blood loss and postoperative drainage were less. The differences were statistically significant (t=6.883, t=8.735; P<0.05). The postoperative pain scores within one week was less than conventional thoracoscopic group. The differences were also statistically significant (t=6.882, t=5.724, t=5.284;P<0.05). The serological indicators, CRP, IL-1, TNF-α,α1-AT levels of patients in the single-hole thoracoscopy group were lower than the conventional group (t=8.293, t=7.274, t=9.284, t=7.183;P<0.05). Conclusion:VATS and conventional hole thoracoscopic surgery can be used for treatment of spontaneous pneumothorax in elderly, but single-hole thoracoscopy has more advantages in reducing surgical trauma and postoperative pain and optimize systemic inflammation associated factors.
4.Recent progress in children with tachycardia-induced cardiomyopathy
International Journal of Pediatrics 2021;48(2):78-81
Tachycardia induced cardiomyopathy is a kind of cardiomyopathy caused by sustained or recurrent tachycardia.Various types of tachyarrhythmias can cause TIC, and the main clinical manifestations of it are cardiac dilatation and cardiac dysfunction.TIC can occur at all ages and is a reversible and acquired cardiomyopathy with a generally benign prognosis.After early diagnosis and reasonable treatment to relive the tachycardia, the function of the heart can partially or completely recover.In clinical practice, pediatricians do not fully understand the disease, as a result, it is easily missed, misdiagnosed, then the proper diagnosis and treatment will be delayed.This article provides a systematic overview of the pathogenesis, clinical characteristics, diagnosis, differential diagnosis, treatment and prognosis of TIC in children, and aims to provide a basis for clinical pediatricians to recognize it early and treat it promptly.

The expression of transforming growth factor-beta1 (TGF-beta1) in placental tissue of pregnancy-induced hypertension (PIH) and the relationship between the level of expression of TGF-beta1 and the amount of vascular cell adhesion molecule-1 (VCAM-1) in serum was studied. Immunohistochemistry ABC was used to detect the expression and distribution of TGF-beta1 in placental tissues in 40 PIH women and 20 normal pregnancy women. High resolution pathological image analysis system was used to determine the quality of TGF-beta1. The VCAM-1 in serum was examined by enzyme linked immunoabsorbent assay (ELISA). The results showed that TGF-beta1 could be express in syncytiotrophoblast. The levels of TGF-beta1 expression in placental tissues of the patients with moderate and severe PIH were significantly higher (P < 0.05), while the serum VCAM-1 was significantly lower than in normal group (P < 0.01). There was a significant positive correlation between the expression of TGF-beta1 in placental tissues and the serum VCAM-1 (r = 0.969, P < 0.01). It was concluded that the level of TGF-beta1 expression in PIH was increased and was positively correlated with the amount of serum VCAM-1, indicating that they might be involved in the pathogenesis of PIH.

Background:Medical treatment and surgery are the two main therapeutic approaches for esophageal variceal bleeding ( EVB),but studies showed that the efficacy of medical treatment was poor,and surgery was invasive and could lead to serious complications. Aims:To investigate the efficacy and safety of endoscopic variceal ligation combined with sclerotherapy for treatment of EVB. Methods:A total of 150 cirrhotic patients with EVB admitted from May 2011 to May 2012 at Wenling Oriental Hospital were enrolled and assigned into observation group and control group by random digital table. Patients in observation group were treated with endoscopic variceal ligation combined with sclerotherapy,and patients in control group were treated with somatostatin and pantoprazole. Overall clinical efficacy,recurrence and adverse effect were compared between the two groups. Results:In observation group,the overall clinical efficacy was 94. 7%(72/76), the recurrence rate was 3. 9%(3/76),and the adverse effect rate was 13. 2%(10/76);in control group,the overall clinical efficacy was 79. 7%(59/74),the recurrence rate was 14. 9%(11/74),and the adverse effect rate was 28. 4%(21/74). Overall clinical efficacy in observation group was significantly higher than that in control group(P<0. 05), while recurrence rate and adverse effect rate were significantly lower than those in control group( P all < 0. 05 ). Conclusions:Compared with medical treatment,endoscopic variceal ligation combined with sclerotherapy is effective in improving the clinical efficacy and reducing the recurrence and adverse effect for treatment of EVB. It is worthy of being used in clinical practice.
