Professor WEI Pin-kang believes that, as a complication of gastric cancer, malignant ascites and gastric cancer have the same pathogenesis: water and dampness retention is the external performance and phlegm resistance is the inner essence. Hence therapy of resolving phlegm and promoting diuresis is suggested for the fundamental treatment of gastric ascites. Using the method of the combination of internal and external treatment, this therapy includes resolving phlegm and draining water medicine both to dispel pathogen and to improve symptoms. Xiaotan LishuiDecoction based on this therapy is composed of Arisacma Cum Bile, processed Pinelliae Rhizome, Cremastrae Pseudobulbus Pleiones Pseudobulbus, old pericarp of bottle gourd, Polyporus, Natriee Sulfas, Phytolaccae Radix and Poria.

Objective : To investigate the epidemiological characteristics of influenza among the elderly in Heilongjiang Province from 2017 to 2021 (April 2017 to March 2022), so as to provide insights into influenza control among the elderly. Methods : The data pertaining to surveillance of patients with influenza-like illness (ILI) at ages of 60 years and older in Heilongjiang Province from 2017 to 2021 were retrieved from Chinese Influenza Surveillance Information Management, and the temporal distribution of ILI cases and the results of influenza virus tests were descriptively analyzed. Results : Totally 26 908 ILI cases at ages of 60 years and older were reported in Heilongjiang Province from 2017 to 2021, with an ILI prevalence rate of 0.17%. The prevalence of ILI appeared a tendency towards a rise in Heilongjiang Province from 2017 to 2021 (χ2trend=268.554, P<0.001), and the epidemic peaked in the 3rd to 7th weeks of 2019 and 2020. The overall positive rate of influenza virus was 6.80%, and the positive rate of influenza virus showed a tendency towards a decline from 2017 to 2021 (χ2trend=425.268, P<0.001). Influenza A (H1N1) pdm09 (46.82%) and A (H3N2) (22.79%), as well as influenza B virus lineages B/Victoria (12.11%) and B/Yamagata (18.28%) were predominant types, which changes among the study period. The detection of influenza virus-positive samples peaked from December to March of the next year, and a high positive rate of influenza virus was detected in Hegang (12.35%), Heihe (11.47%) and Daqing cities (11.07%). There was no significant correlation between the prevalence of ILI and the positive rate of influenza virus in Heilongjiang Province from 2017 to 2021 (rs=-0.800, P=0.104). Conclusions The prevalence of ILI appeared a tendency towards a rise among the elderly at ages of 60 years and older in Heilongjiang Province from 2017 to 2021, and the epidemic peaked in winter and spring. Influenza A (H1N1) pdm09, A (H3N2), B/Victoria, B/Yamagata were alternately prevalent and there was no obvious correlation between ILI prevalence and the positive rate of influenza virus.

AIM: To discuss the protective effects and possible mechanisms of quercetin in oxidative damage of human retina pigment epithelium ( RPE) cells induced by H2 O2 .METHODS: RPE cells were subculture, and they were divided into negative control group: cultured with normal culture medium;oxidative injury group:100 μmol/L H2 O2 treated for 12h; quercetin low dose group: 100 μmol/L quercetin incubated for 24h then treated with 100 μmol/L H2 O2 for 12h; and quercetin high dose group:100 μmol/L quercetin incubated for 24h then treated with 100 μmol/L H2 O2 for 12h. Cell viability were tested by MTT colorimetric detection, apoptosis rate was detected by flow cytometry, apoptotic cell morphology was observed by Hochest33258 staining, expression of catalase (CAT), superoxide dismutase ( SOD) and glutathione peroxidase ( GSH-Px) were tested by colorimetric detection.
RESULTS: Quercetin inhibited H2 O2 - induced cell viability decreased in RPE cells, after treated with different concentrations of quercetin, RPE cells activity increased to (79. 67±4. 98)% and (83. 00±3. 60)%, which had statistical significance difference compared with oxidative damage group (48. 93±3. 39)% (P<0. 05). After treated with different concentrations of quercetin, the apoptosis rate of RPE cells decreased to (23. 23±3. 29)% and (16. 23±1. 94)%, respectively, which had statistical significance difference compared with oxidative damage group (38. 03±4. 76)%(P < 0. 05 ). In addition, quercetin also increased the expression of CAT、SOD、GSH-Px in RPE cells, which had statistical significance difference compared with oxidative damage group.
CONCLUSION:Quercetin effectively inhibited H2 O2 -induced RPE cells damage by improving cell antioxidant enzyme activity, which provide reliable experimental basis for the treatment of injuries in RPE cells.

OBJECTIVETo evaluate the erectile and ejaculatory function of sacral tumor patients after sacral nerve root resection and investigate the relationship of erectile and ejaculatory dysfunction (EED) with the level of sacral nerve injury.

METHODSThis retrospective study included 47 male patients aged 16 to 63 (32.6 +/- 6.8) years treated by sacral tumor resection between January 2008 and August 2013. According to the levels of the sacral nerve roots spared in surgery, the patients were divided into four groups: bilateral S1-S3 (n=16), unilateral S1-S3 (n=21), unilateral S1-S2 (n=6), and unilateral S1 (n=4). The patients were followed up for 12 to 41 (27.2 +/- 10.9) months by questionnaire investigation, clinic review, and telephone calls about their erectile and ejaculatory function at 3, 6 and 12 months after surgery and in August 2013.

RESULTSIn the bilateral S1-S3 group, the incidence rates of EED were 31.25% (5/16), 25% (4/16), and 12.5% (2/16) at 3, 6, and 12 months respectively after surgery, with recovery of erectile and ejaculatory function in August 2013. The incidence rates of EED in the unilateral S1-S3 group were 85.71% (18/21), 71.43% (15/21), 52.38% (11/21), and 42.86% (9/21) at 3, 6 and 12 months and in August 2013, respectively; those in the unilateral S1-S2 group were 100% (6/6), 83.33% (5/6), 83.33% (5/6), and 66.67% (4/6) at the four time points; and those in the unilateral S1 group were all 100% (4/4). No statistically significant differences were found in the incidence rate of EED among the patients of different ages or tumor types (P > 0.05).

CONCLUSIONThe incidence of postoperative EED in male patients treated by sacral tumor resection is closely related to the mode of operation. Sparing the S3 nerve root at least unilaterally in sacral tumor resection is essential for protecting the erectile and ejaculatory function of the patient.
