Purpose:To evaluate the effects of intraoperative radiotherapy for adenocarcinoma gastric cardia.Meth- ods:From Jan.1992 to Dec.2000 a trial on intraoperative radiotherapy for AGC was carried out in 38 patients.Whose age was younger than 75 years,at least on semiliquid diet and no contraindication of surgery.6MV or 9MV-E photon was used for the intraoperative radiation therapy to the cardia,lower segment of the esophagus,fundus,lesser curvature and hepato- gastric ligament.Results:Average follow up 65 months.The 5 year survival rates were 39.4%.Conclusions:Intraoperative radiation therapy is able to improve the results of surgery for adenocarcinoma of the gastric cardia.

Objective To investigate the treatment effects of operation and nerve growth factor on adult multisegmental cervical spinal cord injury without fracture dislocation.Methods Sixty-eight patients with multiple segmental cervical spinal cord injury without fracture dislocation,admitted to our hospital from January 2004 to May 2011,were chosen in our study; according to the will of the patients,18 patients received conservative treatment (group A),25 patients were treated by posterior single open-door laminoplasty (group B) and the other 25 patients were treated with posterior single open-door laminoplasty combined with nerve growth factor (group C,once daily for 4 weeks); their clinical data were retrospectively analyzed.Follow up was performed at 3,6 and 12 months after the treatments;Japanese Orthopaedic Association (JOA) scale was employed to evaluate the clinical efficacy.Results Three,6,12 months after the treatments,the JOA scale scores were statistically different among the three groups (P＜0.05); the scores in group B and C were significantly higher than those in group A at all time points (P＜0.05); 6 and 12 months after the treatmemts,the JOA scale scores in group C were significantly higher than those in group B (P＜0.05).Conclusion To patients with multisegmental cervical spinal cord injury without fracture dislocation,conservative treatment can make the spinal cord function partially restored,but the effect is limited; exogenous nerve growth factor has good repairing effect on spinal cord injury.

Oral epidemic diseases of exposure personnel in long-term low-dose radiation yet have rarely been studied. Referred to WHO oral health survey method and symptom grading standard, data of 341 exposure persons in long-term low-dose radiation including α particle, β particle, and γ rays, etc., were collected from one camp in China in 2011 with cluster sampling and analyzed? with Foxpro 6.0 and SPSS 16.0 software. The exposure persons worked in low-dose radiation for a long time aged between 23 and 56, whose average age were 27.1 years old.In addition, their lengths of service were from 2 to 34 years (average 7.9 years) and average exposure time was 8 hours a day each year for more than three months. Average annual radiation dose equivalent was from 1.8 to 16.5 mSv (average 7.3 mSv). Total radiation dose equivalent was from 3.8 to 425.0 mSv (average 97.3 mSv).

To analyze the impact of hepatitis B virus (HBV) infection on liver function of patients after hematopoietic stem cell transplantation (HSCT), the transplantation outcome of 48 patients infected with HBV prior to transplantation among 185 patients received HSCT was investigated retrospectively. The results showed that during a follow-up for 6 months after HSCT, the alanine aminotransferase (ALT) peak average values of the patients with HBsAg(+), HBsAb(+) and control groups were (281.6 ± 414.6), (95.4 ± 79.9) and (65.1 ± 44.2) U/L, respectively. The incidences of abnormal liver function of the patients with HBsAg(+), HBsAb(+) and control groups were 61.54%, 40.00% and 30.23% respectively. There were no significant differences between any two groups (P > 0.05). The lethality of those patients at late period after transplantation was not related to HBV infection. The hepatocirrhosis and hepatocarcinoma caused by HBV infection have not become major problems in long-term survivors. It is concluded that in HBsAg(+) patients received HSCT, the damage of liver function is more severe than control group, possibly increasing the development of abnormal liver function. The measures against the liver function damage should be taken. The prophylactic administration of ganciclovir for virus may be effective to prevent the activation of HBV.

Objective:To summarize the incidence of cerebral venous reflux (CVR) in patients with recent small subcortical infarct (RSSI) and explore its correlation with enlarged perivascular spaces (EPVS).Methods:Patients with RSSI in the lenticulostriate artery admitted to the Department of Neurology of the First Affiliated Hospital of Zhengzhou University from January 2019 to December 2022 were included. The baseline demographic data, medical history, and laboratory results of the patients were collected. CVR was assessed by time-of-flight magnetic resonance angiography. Patients were stratified into 2 groups based on the presence (CVR group) or absence of CVR (non-CVR group), and baseline characteristics as well as laboratory test results were compared between the 2 groups. The location and number of EPVS were evaluated using a visual grading scale, with EPVS with higher scores defined as high-grade EPVS (HEPVS). Simultaneous evaluation of cerebral white matter hyperintensities and lacunar infarctions was conducted, followed by intergroup comparisons. The relationship between EPVS and CVR was studied using multiple Logistic regression analysis.Results:A total of 571 patients with RSSI in the lentiform artery area were ultimately included, including 180 females (31.5%). Their age was (59.37±12.87) years. Among them, 73 patients (12.8%) exhibited CVR based on imaging findings, so the incidence of CVR was 12.8%. In comparison between the CVR group ( n=73) and the non-CVR group ( n=498), the proportion of females [21.9% (16/73) vs 32.9% (164/498), χ 2=3.578, P=0.059] was lower and the proportion of history of smoking [38.4% (28/73) vs 27.7% (138/498), χ 2=3.499, P=0.061] was higher in the CVR group, but without statistical significance. Additionally, the history of alcohol consumption [34.2% (25/73) vs 21.7% (108/498), χ 2=5.621, P=0.018] and the proportion of patients with concomitant HEPVS in the basal ganglia area [41.1% (30/73) vs 25.3% (126/498), χ 2=7.999, P=0.005] was higher in the CVR group with statistical significance. Multiple Logistic regression analysis showed that HEPVS in the basal ganglia region remained independently associated with CVR ( OR=1.988, 95% CI 1.190-3.320, P=0.009). Conclusion:EPVS in the basal ganglia region is significantly associated with CVR in the RSSI population, suggesting that venous dysfunction may be closely related to the formation of EPVS.

To discuss the effects of total glucosides from white paeony on preventing and treating radioactive liver damage, and explore its possible mechanisms. Thirty-six patients with primary hepatic carcinoma from 105th Hospital of Chinese PLA were treated with 3-dimensional conformal radiotherapy and randomly divided into simple irradiation group, total glucosides from white paeony group, and control group. The levels of AST, ALT, HA, LN, PCⅢ, CIV and TGF-β1 in serum of various groups were determined by using ELISA method. As compared with the simple irradiation group and control group, total glucosides from white paeony could obviously decrease the levels of AST, ALT, HA, LN, PCⅢ, CIV and TGF-β1(P<0.05, P<0.01). The results showed that the total glucosides from white paeony could effectively prevent and treat radioactive liver damage, and its mechanism might be associated with decreasing the levels of TGF-β1, and inhibiting the synthesis of collagen synthesis.
