Promoting effect of panaxatriol ginsenoside ( PTGS ) on inter-leukine-3(IL-3 ) induction of phyto-hemagglutinin ( PHA ) stimulated human lymph node cells was observed. The results showed that PTGS enhanced the IL-3 production on each time of IL-3-induction kinetics, maximally by 30% ( 72h ) . Furthermore, it was observed that IL-3 mRNA from PHA+PTGS-stimulated lymph node cells translated more IL-3 than PHA-stimulated lymph node cells on each time of IL-3 mRNA-induction kinetics, maximally by 40% ( 60h ) , using the methods of wheat germ cell-free in vitro translation system and IL-3 bioassay.

Under stimulation of PHA,PHA + TPA,or PHA + PTS the time ke-netics of DNA,RNA,protein synthesis and lymphokine secretion by human lymph node cell expressed different responses. The PTS did not increase the DNA and RNA synthesis, but increased the protein synthesis ( 60% ) . TPA increased the RNA synthesis ( 18% ) , therefor increased the protein synthesis ( 40% ) . Both of TPA and PTS increased the production of 5 kinds of lymphokines (IL-1 , IL-2 , IL-3, BCGF, TFNr). We infer that PTS and TPA increase the lymphokine production through different gene regulation. TPA Promotes the translation of lymphokine mRNA。

Large scale preparation of human IL-2 mRNA was obtained from human spleen cells stimulated with PHA+TPA at the peak of IL-2 mRNA transcription. Full length of IL-2 mRNA was translated in wheat germ extract to produce bioactive IL-2 (tIL-2). The IL-2 mRNA was about 14 S depending on the 7 M Urea-SDS-PAGE, and recovried from gel and translated in vitro. The elute curve of tIL-2 was the same as that of recombinant IL-2 (rIL-2) and natural IL-2 (nIL-2), the molecular weight of tIL-2 was about 14.000 dalton. The translational process of IL-2 mRNA in vitro was inhibited when RNA was cultured with RNase or translated product was cultured with proteinase, proving a standard in-vitro translation.

Objective:To investigate the current status of prevention and treatment of esophagogastric variceal bleeding (EVB) in cirrhotic portal hypertension patients in Ningxia region.Methods:The retrospective and descriptive study was conducted. The clinical data of 820 cirrhotic portal hypertension patients who were admitted to 21 medical centers in Niangxia region from January 2018 to December 2020 were collected, including 85 cases in Ningxia Hui Autonomous Region People′s Hospital, 73 cases in the Fifth People′s Hospital of Ningxia Hui Autonomous Region, 59 cases in the Wuzhong People′s Hospital, 52 cases in the Qingtongxia People′s Hospital, 50 cases in the Guyuan People′s Hospital, 47 cases in the Yuanzhou District People′s Hospital of Guyuan City, 47 cases in the Yinchuan Second People′s Hospital, 40 cases in the General Hospital of Ningxia Medical University, 40 cases in the Tongxin People′s Hospital, 35 cases in the Yinchuan First People′s Hospital, 34 cases in the Third People′s Hospital of Ningxia Hui Autonomous Region, 32 cases in the Zhongwei People′s Hospital, 30 cases in the Lingwu People′s Hospital, 30 cases in the Wuzhong New District Hospital, 30 cases in the Yanchi People′s Hospital, 29 cases in the Ningxia Hui Autonomous Region Academy of Traditional Chinese Medicine, 28 cases in the Shizuishan Second People′s Hospital, 25 cases in the Shizuishan First People′s Hospital, 21 cases in the Haiyuan People′s Hospital, 20 cases in the Pengyang People′s Hospital, 13 cases in the Longde People′s Hospital. There were 538 males and 282 females, aged (56±13)years. Observation indicators: (1) clinical charac-teristics of cirrhotic portal hypertension patients; (2) overall prevention and treatment of EVB in cirrhotic portal hypertension patients; (3) prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Results:(1) Clinical characteristics of cirrhotic portal hypertension patients: of 820 cirrhotic portal hypertension patients, 271 cases were in compensated stage and 549 cases were in decompensated stage. Of the 271 cases in compensated stage, there were 183 maels and 88 females, aged (53±12)years. There were 185 Han people, 85 Hui people and 1 case of other ethic group. The etiological data of liver cirrhosis showed 211 cases of viral hepatitis B, 4 cases of alcoholic liver disease, 8 cases of viral hepatitis C, and 48 cases of other etiology. There were 235 cases of Child-Pugh grade A and 36 cases lack of data. Of the 549 cases in decompensated stage, there were 355 males and 194 females, aged (57±14) years. There were 373 Han people, 174 Hui people and 2 cases of other ethic group. The etiological data of liver cirrhosis showed 392 cases of viral hepatitis B, 33 cases of alcoholic liver disease, 10 cases of viral hepatitis C, and 114 cases of other etiology. There were 80 cases of Child-Pugh grade A, 289 cases of grade B, 170 cases of grade C and 10 cases lack of data. (2) Overall prevention and treatment of EVB in cirrhotic portal hypertension patients: of 271 patients in compensated stage, 38 cases received non-selective β-blocker (NSBB) therapy, 16 cases received endoscopic treatment, 6 cases received interventional therapy. Of 549 patients in decompensated stage, 68 cases received NSBB therapy, 46 cases received endoscopic treatment, 28 cases received interventional therapy. (3) Prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals: of 271 patients in compensated stage, 181 cases came from tertiary hospitals, of which 28 cases received NSBB therapy, 15 cases received endoscopic treatment, 6 cases received interventional therapy. Ninety cases came from secondary hospitals, of which 10 cases received NSBB therapy, 1 cases received endoscopic treatment. There was no significant difference in NSBB for prevention of EVB between tertiary and secondary hospitals ( χ2=0.947, P>0.05), while there was a significant difference in endoscopic treatment for prevention of EVB between tertiary and secondary hospitals ( χ2=5.572, P<0.05). Of 549 patients in decompensated stage, 309 cases came from tertiary hospitals, of which 22 cases received NSBB therapy, 29 cases received endoscopic treatment, 22 cases received interventional therapy. Two hundreds and fourty cases came from secondary hospitals, of which 46 cases received NSBB therapy, 17 cases received endoscopic treatment, 6 cases received interven-tional therapy. There were significant differences in NSBB and interventional therapy for prevention of EVB between tertiary and secondary hospitals ( χ2=18.065, 5.956, P<0.05). Conclusions:The proportion of receiving EUB prevention in cirrhotic portal hypertension in Ningxia is relatively low. For patients with compensated liver cirrhosis, the proportion of NSBB therapy and endoscopic treatment in the secondary hospitals was lower than that in tertiary hospitals. For patients with decompensated liver cirrhosis, the proportion of interventional treatment in secondary hospitals is lower than that of tertiary hospitals, but the proportion of NSBB in secondary hospitals taking is higher than that of tertiary hospitals.
