“Inflammation-cancer” transformation of chronic atrophic gastritis （CAG） refers to the process in which the gastric mucosa， in the context of CAG， progresses through stages of precancerous lesions of gastric cancer （PLGC）， such as intestinal metaplasia and dysplasia， and eventually develops into gastric cancer （GC）. In China， the incidence and mortality rates of GC rank among the highest in the world， and the proportion of GC cases caused by gastric mucosal infection and inflammation has been increasing. Modern medical treatments for CAG and PLGC mainly rely on drug therapy， endoscopic resection， and regular surveillance. Although these disease management strategies are relatively mature， they present limitations in early lesion prevention and recurrence risk control. Therefore， it is imperative to identify therapeutic approaches for CAG and PLGC that offer preventive， reversible， and recurrence-reducing benefits. With advances in research on the mechanisms underlying inflammation-cancer transformation and the integration of traditional Chinese and Western medicine， the advantages of TCM in preventing and even reversing early-stage CAG and PLGC have gradually become apparent. This review explored the mechanisms of inflammation-cancer transformation in CAG from five aspects： inflammatory microenvironment， autophagy， glycolysis， bile acids， and ferroptosis. In conjunction with TCM theory and a deeper understanding of the distinct mechanisms involved in the inflammation-cancer transformation of CAG， this review further discussed the specific mechanisms through which TCM intervened in treating CAG and PLGC， with the aim of providing theoretical support and therapeutic insights for future clinical applications.

Objective:To investigate the effects of high-energy shock and vibration on cortex injury and peripheral blood immune cells in goats.Methods:Seventeen Boer goats without gender preference were selected. By using random number tables, the goats were divided into normal control group ( n=5) and shock and vibration injury group ( n=12). The goats in the normal control group were anatomized routinely and their brain was collected after being sacrificed without any other treatment. The goats in the high-energy shock and vibration model group were placed on a loading table (part of the BY10-100 instant shock and vibration simulation platform) in a restrained state, and made into a high-energy shock and vibration injury model induced by a vertical impact waveform generator. The intravenous blood samples were taken from the goats in the shock and vibration injury group before and at 0, 3, 6 and 24 hours after injury.Then, the goats were sacrificed and the following procedures were the same as the normal control group. At 24 hours after injury, the brain injury and the histopathological changes of the cerebral cortex in the normal control group and shock and vibration injury group were observed by gross pathological and anatomical examination and HE staining. The mRNA expression of zonula occludens 1 (ZO-1), tight junction protein 5 (Claudin-5), glial fibrillary acidic protein (GFAP), ionized calcium binding adaptor molecule 1 (IBA-1), interleukin (IL)-1β, IL-6 and cluster of differentiation antigen 177 (CD177) of the cerebral cortex in the normal control group and shock and vibration injury group were measured through fluorogenic quantitative polymerase chain reaction. The expression of ZO-1 and Claudin-5 proteins of the cerebral cortex in the normal control group and shock and vibration injury group were detected by Western blotting. Hematology analyzer and coagulation analyzer were used to detect white blood cell count, neutrocyte, lymphocyte, monocyte, prothrombin time 1 (PT-1), prothrombin time international normalized ratio (PT-INR), activated partial thromboplastin time (APTT), thrombin time (TT), prothrombin activity (PTA) and fibrinogen (FIB) levels in goats of the shock and vibration injury group before and at 0, 3, 6 and 24 hours after injury, respectively. Results:At 24 hours after injury, no visible contusion or necrosis was found in goat brain tissue in the shock and vibration injury group; the cerebral micro-vessels presented with a local dilation, hyperemia, edema, aggregation of inflammatory cells, disruption of vessel walls and leakage of red blood cells. These changes were not observed in the normal control group. In the shock and vibration injury group, ZO-1 and Claudin-5 mRNA expressions in the cerebral cortex were 0.25±0.10 and 0.09(0.04, 0.44) respectively, which were significantly lower than those of the normal control group [1.00±0.15 and 0.99(0.80, 1.20)]; GFAP, IBA-1, IL-1β, IL-6 and CD177 mRNA expression levels were 4.40(3.88, 6.75), 2.60±1.07, 3.04±0.51, 2.71±0.45 and 2.93±0.62 respectively, which were significantly higher than those of the normal control group [1.00(0.78, 1.22), 1.00±0.37, 1.00±0.27, 1.00±0.57 and 1.00±0.35]; ZO-1 and Claudin-5 protein expression levels were 0.41±0.06 and 0.42±0.11 respectively, which were significantly lower than those of the normal control group (1.08±0.12 and 0.91±0.23) (all P<0.01). In the shock and vibration injury group, the levels of white blood count, neutrocyte, and lymphocyte in peripheral blood were (13.7±3.3)×10 9/L, (35.3±14.8)% and (57.2±15.1)% respectively before injury, (19.4±3.1)×10 9/L, (60.5±12.5)% and (33.6±14.2)% respectively at 3 hours after injury, and (20.6±3.6)×10 9/L, (63.6±13.0)% and (30.9±15.0)% respectively at 6 hours after injury. By contrast, the levels of white blood count and neutrocyte were significantly increased but the level of lymphocyte was significantly decreased at 3 and 6 hours after injury ( P<0.05 or 0.01); the levels of the above indicators showed no significant changes at 0 and 24 hours after injury (all P>0.05); the level of monocyte did not change significantly at all time points before and after injury (all P>0.05). The levels of PT-1, PT-INR, APTT, TT, PTA and FIB in the shock and vibration injury group did not change significantly at each time point before and after injury (all P>0.05). Conclusion:Cerebral cortex microvascular injury and disruption of blood-brain barrier can be initiated in the early stage of high-energy shock and vibration injury in goats, accompanied by the presence of central and peripheral inflammatory response.

Objective:To analyze the clinical efficacy and safety of endoluminal treatment of complex renal artery aneurysm (RAA).Methods:The clinical data and follow-up results of 19 patients with complex RAA admitted to Renji Hospital, Shanghai Jiaotong University School of Medicine from November 2014 to September 2021 were retrospectively analyzed. Two patients were treated with simple spring coil embolization into the aneurysmal artery, 14 patients were treated with simple spring coil embolization of the aneurysmal cavity, and 3 patients were treated with stent-assisted + spring coil embolization technique. Based on the location of the aneurysm, RAA were classified into type Ⅰ, Ⅱ, and Ⅲ. 7 patients with type Ⅰ, 10 patients with type Ⅱ, and 2 patients with type Ⅲ were studied. Variance analysis was used to compare the differences in glomerular filtration rate(GFR) of the affected side when the tumor was located at different locations, and Pearson was used to analyze the correlation between the number of coils implanted and the size of the tumor and GFR.Results:Ten of the 19 patients who were underwent successful endoluminal intervention. The average size of the patients′ aneurysms was (20.89±6.65) mm, and the average number of spring coils implanted was 8.22±3.08. The preoperative and postoperative serum creatinine were in the normal range, and no RAA tumor enlargement or recurrence was found during the follow-up period. The postoperative GFR was abnormal in patients with type Ⅰ, type Ⅱ, and type Ⅲ renal aneurysms, and the mean GFR value differed among the three types of patients( P=0.003). There was a negative correlation between the postoperative GFR values of the affected kidney and the number of spring coils implanted ( P=0.047), and no significant relationship between GFR and aneurysm size. Conclusion:The endovascular technique is an effective and safe means of treating complex RAA.

Objective:To explore the influence of online and offline family therapy based on the Satir model on emotions of adolescents with depressive disorder and their parents in remote areas.Methods:A total of 98 cases adolescents with depressive disorder treated in the psychosomatic medicine of the Second Affiliated Hospital of Nanchang University from January 2021 to June 2021 and their parents were selected as the objects. The adolescents with depressive disorder and their parents were randomly divided into the control group (49 parents and 49 adolescents) and the observation group (49 parents and 49 adolescents). The control group received the medical treatment (sertraline 100 mg/d) and the routine health education, while the observation group received the online and offline Satir family therapy on the basis of the intervention of the control group. Generalized anxiety disorder-7 (GAD-7) and patient health questionnaire-9 (PHQ-9) were used to investigate the negative emotions of the parents of the two groups before and 12 weeks after the intervention. The screen for child anxiety related emotional disorders (SCARED) and depression self-rating scale for childhood (DSRS) were used to investigate the negative emotions of the adolescents before and 12 weeks after the intervention.The SPSS 20.0 software was used for statistical analysis. t test was used to compare the SCARED scale score and DSRS score changes of the adolescents in the two groups, and χ 2 test was used to compare the proportional changes of parents' anxiety and depression. Results:The scores of SCARED (51.55±12.69 vs 36.82±7.69, t=15.839) and DSRS (25.08±4.81 vs 16.88±2.16, t=13.047) of adolescents in the control group were significantly different before and after the intervention (both P<0.05). The scores of SCARED (51.16±15.84 vs 31.31±7.72, t=14.385) and DSRS (24.12±4.81 vs 14.08±2.03, t=14.723) of adolescents in the observation group were significantly different before and after the intervention (both P<0.05). After the intervention, the scores of SCARED and DSRS in the observation group were lower than those in the control group ( t=3.540, 6.609, both P<0.05). Before intervention, there was no significant difference in the proportion of anxiety and depression between the parents of the two groups (χ 2=1.837, 3.547, both P>0.05). After 12 weeks of intervention, there was a statistically significant difference in the proportion of anxiety and depression between the two groups, which were lower in the observation group than those in the control group (χ 2=5.995, 4.009, both P<0.05). Conclusion:Online + offline family therapy based on the Satir model can not only effectively reduce anxiety and depression of adolescents, but also effectively reduce anxiety and depression of their parents.It is especially suitable for outpatient management of children with depressive disorder in remote areas.

Objective:To investigate whether the clinical efficacy of mechanical pharmacothrombectomy (PMT) in treatment of whole-lower-limb acute deep vein thrombosis (DVT) could be improved by the modified approach removing popliteal vein thrombosis.Methods:From Mar 2016 to Mar 2018, 31 patients with whole-lower-limb acute DVT were enrolled and treated with PMT by AngioJet. The clinical data was retrospectively analyzed, and the clinical efficacy was evaluated.Results:26 cases were treated by contralateral common femoral vein approach and the other 5 cases by ipsilateral calf deep vein. Urokinase was given in bolus in 29 patients before thrombectomy. After PMT, 7 cases combined with catheter-directed thrombolysis. 26 cases underwent iliac vein PTA, and 14 cases underwent iliac vein stenting. The average hospitalization days was (7.6±1.8) d. The thrombus clearance rate was grade Ⅱ (50%~99%) in 16 cases (51.6%) and grade Ⅲ (100%) in 15 cases (48.4%). 30 patients were followed up and the mean follow-up time was 19.7 months. The 12-month primary patency rate was 83.3%. All the 5 patients with occlusion had different degrees of post-thrombotic syndrome (PTS), and the incidence of PTS was 16.7% (5/30).Conclusions:The modified approach to treat the whole-lower-limb acute deep vein thrombosis with PMT is safe and effective. The popliteal vein thrombosis can be cleared in one stage. The blood inflow can be improved, and the incidence of PTS is relatively low.
