OBJECTIVE:To observe the efficacy and safety of proton pump inhibitors combined with Compound digestive en-zyme tablet in the treatment of epigastric pain syndrome with abdominal distension. METHODS:156 patients with epigastric pain syndrome with abdominal distension were randomly divided into control group(75 cases)and observation group(81 cases). Con-trol group was given 40 mg Esomeprazole enteric-coated tablet for once half an hour before breakfast;observation group was addi-tionally given 243.6 mg Compound digestive enzyme tablet immediately after meal,3 times a day. The treatment course for both groups was 2 weeks. Clinical efficacy,clinical symptom score,pepsinogenⅠ(PGⅠ),pepsinogenⅡ(PGⅡ),2,4 h postprandial gastric emptying rate before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:The to-tal effective rate in observation group was significantly higher than control group,the difference was statistically significant (P<0.05). There was no significant difference in the incidence of adverse reactions between 2 groups (P>0.05). Before treatment, there were no significant differences in the clinical symptom score,PGⅠ,PGⅡand 2,4 h postprandial gastric emptying rate(P>0.05). After treatment,clinical symptom score in 2 groups were significantly lower than before,and observation group was lower than control group;PGⅠ and PGⅡ in observation group were significantly higher than before and control group,the differences were statistically significant(P<0.05);and there were no significant differences in the 2,4 h postprandial gastric emptying rate be-tween 2 groups and PGⅠ and PGⅡ in control group before and after treatment(P>0.05). CONCLUSIONS:The efficacy of pro-ton pump inhibitors combined with Compound digestive enzyme tablet is superior to the proton pump inhibitors in the treatment of epigastric pain syndrome with abdominal distension,with similar safety.

Coronaviruses of the genus Coronavirus contain a variety of human pathogenic viruses, and the development of anti-coronavirus drugs is of great value. The development of antiviral drugs targeting host cells is not only helpful for the development of new antiviral strategies, but also for solving problems such as drug resistance due to viral mutations. Our preliminary study identified that cell cycle-dependent protein kinases (CDKs) involved in coronavirus replication, for which they would be potential anticoronaviral targets. In this study, we found that the broad-spectrum CDK inhibitor flavopiridol significantly inhibited severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA dependent RNA polymerase (RdRp) activity. Further studies showed that flavopiridol suppressed the RNA synthesis efficiency of SARS-CoV-2 RdRp. In addition, flavopiridol effectively restricted the replication of human coronavirus OC43 (HCoV-OC43). Therefore, our study suggested that the CDK inhibitor flavopiridol may be a potential anticoronaviral drug.

This study reported the protective effects of poly-saccharide sulphate (PSS) on experimental model of myocardial infaction by high positioned double - ligation of the anterior descending left coronary artery in rabbits, and on ischemic injury of myocardium by intraperi-toneal injection of isoprenaline in rats. The results showed that PSS could decrease the infarct sizes of rabbits model expressed by ECG mappingof ∑ST segment, NST and NQ, and reduce the activities of CPK in serum. It also showed that PSS reduced the severity of myocardial necrosis and the activies of CPK in serum of the experimental rats . It suggested that PSS have the protective effects on ischemic injury of myocardium.

The discovery and use of antibiotics is one of the most important breakthroughs in medical history.However, the uprising and spread of the drug-resistance bacterial pathogens have posed a great threat on human health once again.There is an urgent need to develop new antibiotics.Traditional Chinese medicine contains a large volume of bioactive substances suited for novel antibiotic development.However, clinical use of antibiotics of Chinese medicine originis are very rare despite the fact that Chinese medicine has been used for infectious diseases for many years.In this paper, we propose a new mechanism of action for Chinese medicine in treating infectious diseases based on our experimental data.Unlike conventional antibiotics which kill pathogens or inhibit their growth, the traditional Chinese medicine probably function through repressing bacterial pathogenicity.That is, they are actually “antipathogenic drugs”.There are several advantages these antipathogenic drugs possess over traditional antibiotics, including that pathogens are less likely to develop resistance and the drugs have less effect on normal members of the human microbe.

Objective To investigate the effects of Erigeron breviscapus Hand Mazz(EBH) on learning and memory dysfunction in mice with cerebral ischemia/reperfusion injury.Methods 40 mice were randomly divided into control group, sham operated group, model group and EBH group, with 10 mice each. Mice model of cerebral ischemia/reperfusion injury was established by bilateral common carotid artery blocking. 7 days before and after operation, the mice in EBH group were injected I.p.with EBH injection 0.15 ml/d, while those in other groups were injected I.p. with saline 0.15 ml/d. The learning and memory function was tested by Morris water maze.Results The latent period in the model group was longer than that in the normal group and the sham operated group (P<0.05). EBH could shorten the latent period significantly as compared with those in the model group (P<0.05).Conclusion EBH can improve learning and memory function in cerebral ischemia/reperfusion injured mice.

ObjectiveTo investigate the effects of Aniracetam on learning and memory dysfunction in mice with cerebral ischemia/reperfusion injury. Methods48 mice were randomly divided into control group, sham operated group, model group and Aniracetam group, with 12 mice each. Mice model of cerebral ischemia/reperfusion injury was established by bilateral common carotid artery blocking. The learning and memory function was tested by Morris water maze.ResultsThe latent period in the model group was longer than that in the normal group and the sham operated group (P<0.05). Aniracetam could shorten the latent period significantly as compared with those in the model group (P<0.05). ConclusionAniracetam has effects in improving learning and memory function in cerebral ischemia/reperfusion injured mice.

Objective To investigate the relationship of RhoA and Snail expressions, and the invasion and metastasis in salivary adenoid cystic carcinoma (SACC). Methods The expressions of RhoA protein and Snail protein in 55 samples of SACC (SACC group ) and 20 samples of para-carcinoma normal tissues(control group) were detected using immunohisto?chemical method. The relationship between RhoA protein and Snail protein expressions and clinical and pathological charac?teristics were analyzed. Results The positive expressions of RhoA protein (69.1% vs 5.0%) and Snail protein (72.7% vs 10.0%) were significantly higher in SACC group than those in control group (P < 0.05). The positive expression rates of RhoA protein and Snail protein were significantly higher in patients with lymph node metastasis than those in patients with?out lymph node metastasis. The positive expression rates of RhoA protein and Snail protein were significantly higher in pa?tients atⅢ+Ⅳstage than those in patients atⅠ+Ⅱstage. The positive expression rates of RhoA protein and Snail protein were significantly higher in substantive carcinal tissues than those in screen roller type and tubular carcinal tissues. The posi?tive expression of Snail protein was significantly higher in substantive and tubular carcinal tissues than that in screen roller type carcinal tissues (P<0.05). There were no significant differences in positive expression rates of RhoA and Snail between different gender, age and different carcinal tissues. There was a positive correlation beween expression rates of RhoA and Snail protein in SACC (r=0.414, P<0.001). Conclusion RhoA and Snail may both facilitate the infiltration and metastasis of SACC through RhoA/ROCK/PKD1/NF-kappa B/Snail signaling pathways.

BACKGROUND:The improvement of athletic achievements needs a super-limited exercise to gain,how to protect athletics health under the prerequisite of gaining excellent achievements?OBJECTIVE:To reduce the injury of athletic renal function following maximum exercise by using traditional Chinese medicinal methodDESIGN:A randomized and controlled trial,taking students majoring in sports education specialty as subjects.SETTING:Internal Medicinal Department of Traditional Chinese Medicine (TCM) Hospital of Qufu Hospital of Traditional Chinese Medicine and Sports Education College of Qufu Normal University.PARTICIPANTS :Two small natural classes were randomly drown up from 16 small natural classes of 2000 grade in Sports Education College of Qufu Normal University, with 20 students in each class, on April 20, 2004.METHODS:All 40 students were according to natural class divided as experimental class and control class.The urine specimens for test were collected 15-20 minutes after one time maximum loading training on April24,2004 and immediately after morning getting-up. The procedure was performed once more on May 24. During the process the students in experimental group had taken the capsule of kidney-and-spleen-strengthening Chinese drug (KSSD, containing mainly Rhizoma Dioscoreae, Radix Polygoni Multiflori, Herba Epimedii, Fructus Lycii, Gynostamma Pentaphyllum,Radix Acanthopanacis Senticosi,Radix Salviae Miltiorrhizae,Radix Bupleuri, etc., 0.3 g/pellet), 6 pellets, 3 times a day. Urinary glucoprotein,β2-microglobulin, albumin and globulin were detectedby radio-immunoassay.MAIN OUTCOME MEASURES:The changes of urinary proteins of the students before and after administration following maximum exercise and getting-up in next morning.RESULTS: All students involved were good for the trial, without any loss.① The contents of various urinary proteins for the subjects after the maximum exercise or before administration were all obviously increased,and the conditions of natural recovery of proteinuria on getting-up next morning were quiet different: the recovery of urinary albumin was the fattest, basically to the normal;recoveries of β2 micro-globulin and immune-globulin were obvious, but the recovery of glucoprotein was inconsiderable.② After the second trial,in comparing the experimental group with the control group it was found that KSSD can obviously influence the recovery of proteinuria following maximum exercise:The effect in 12 hours did not be shown because of too fast natural recovery of albuminuria. It could promote the recoveries of β2 micro-globulin and immune-globulin. The effect on recovery of urinary of glucoprotein was obvious,basically to the normal for experimental group and basically no change for control group,there was a significant differentiation between the two groups.CONCLUSION:The contents of urinary proteins were obviously increased following maximum loading training, and natural recoveries of the four kinds of proteins presented regulatory changes.KSSD can promote the recovery of proteinuria following maximum exercise to normal volume,suggesting that the medicine has a protecting role to renal function.
