The perioperative total serum CK and CK-MB activities were determined in 38 patients with carcinoma of the esophagus and cardia of the stomach with fluorometric and cylinder layer chromatography. The data were compared with those obtained from 18 patients undergoing pulmonary operation and 20 normal subjects. The results suggest that: (1) carcinoma of the esophagus and cardia of the stomach could not induce variation of the total serum CK and CK-MB; (2) the elevation of the total serum CK after esophagogas-trostomy might probably be due to the trauma of the skeletal muscles of the chest wall;(3)the total serum CK is non-specific for the diagnosis of AMI in the perioperation period,but CK-MB might be considered as a specific enzyme criteria.

Objective To compare of flexible ureteroscope holmium laser lithotripsy and percutaneous nephrolithotomy in treating renal stones of ≤2cm.Methods In this retrospective study,we compared 120 patients of renal pelvic stones of ≤2cm size treated with FURS(n=62)or PCNL(n=58).Factors such as operation time,hospitalization time,stone-free rate(SFR),drop in haemoglobin level,and complications were analyzed.Results The stone burden of the FURS group and PCNL group was(1.4±0.2)cm and(1.6±0.3)cm respectively.In FURS group,The operation time was(28±12)min with postoperatlve fever in 3 cases;he hospitalization time was(3.7±1.8)days.The decrease of hemoglobin was(0.18±0.06)g/L.No major complication was recorded.The SFR was 85.5%(53/62)one week postoperatively and 95.2%(59/62)one month postoperatively.In PCNL group,the operation time was (42±15)min with postoperative fever in 2 cases and bleeding in 2 case.The hospitalization time was 6.8±1.5 days.The decrease of hemoglobin was(14.30±3.50)g/L.The SFR was 91.4%(53/58)one week postoperatively and 96.6%(56/58)one month postoperatively.Conclusion For renal stones≤2cm,FURS has the advantages of shortening operation time,reducing blood transfusion requirements,decreasing postoperative complications with a farely SFR compared with PCNL.FURS is a good alternative.

ObjectiveTo observe the effect of acupoints stimulation with silver spike point therapy on insomnia.Methods60 patients with insomnia were randomly divided into the trial group and control group with 30 cases in each group. Patients of the trial group were treated by acupoints stimulation with silver spike point therapy and patients of control group were treated only with Clonopin.

OBJECTIVE: To investigate the clinical characteristics of ocular symptoms in patients with allergic rhinitis (AR) and the impact of the ocular symptoms on patients' quality of life. METHOD: AR patients' history and clinical data were collected and analyzed. One hundred cases were extracted from adult patients with and without ocular symptoms in each group and their quality of life were evaluated using rhino-conjunctivitis quality of life questionnaire (RQLQ). RESULT: Totally 1119 cases were collected and 859 cases had ocular symptoms. Of the patients with ocular symptoms, 582 cases were mild, 234 cases were moderate, 43 cases were severe. Eye itching was the most common symptom, followed by tears, hyperemia and swelling. Patients with ocular symptoms had longer disease history than non ocular symptom group (P < 0.05). There was a positive correlation between ocular and nasal symptoms (P < 0.01); patients with ocular symptoms had more severe nasal symptoms than patients without ocular problems; while patients with moderate to severe AR had more severe ocular symptoms than mild AR patients (P < 0.01). Female patients had higher incidence (P < 0.05) and ocular symptoms score (P < 0.05) than male. Children less than 10 years old had a relative lower incidence and score of ocular symptoms. While the incidence and score had an increasing trend for patients older than fifty. There was no difference regarding the type and number of allergen in the patients with and without ocular symptom. Moreover, patients with ocular symptoms had higher scores in the domains of non-nose/eye symptoms, practical problems, ocular symptoms, emotional function and total score in RQLQ than patients without ocular symptom. CONCLUSION It was common for the AR patients to have ocular symptoms, and ocular symptoms had obvious influence on the patients' quality of life. So controlling of the ocular symptoms should not be ignored during the diagnosis and treatment of AR.

Objective To investigate the clinical therapeutic effect of Chaishi fever particles on patients with epidemic encephalitis B and to study the machanism of anti-inflammatory.Methods One hundred and twenty one patients with epidemic encephalitis B admitted to the Second Clinical Medical College of Henan University of Chinese Medicine from January 2014 to May 2017 were enrolled, and they were divided into a routine treatment group (60 cases) and a traditional Chinese medicine (TCM) treatment group (61 cases) by random number table. The patients in routine treatment group were given symptomatic support and comprehensive treatment for 15 days, while those in the TCM treatment group were given as that of routine group with the addition of Chaishi fever particles 8 g, 4 times every day, orally taken for consecutive 15 days. The levels of tumor necrosis factor-α (TNF-α), interleukin (IL-1β, IL-10) in the serum of two groups were determined by enzyme-linked immunosorbent assay (ELISA), and the clinical therapeutic effect, complications and sequelae in two groups after treatment were observed.Results Compared with the routine treatment group, after treatment the time of body temperature recovering normal (days: 5.8±1.2 vs. 7.5±1.7), the coma time (days: 5.5±1.3 vs. 6.8±1.6), the remission time of convulsion (days: 5.2±1.4 vs. 6.5±1.5), and the length of stay in hospital (days: 22.6±1.9 vs. 25.2±1.8 ) were significantly shorter in TCM treatment group (P < 0.05). After treatment, the levels of serum tumor TNF-α and IL-1β were decreased, IL-10 was increased in both groups, moreover, compared with the routine treatment group, the changes were more obvious in TCM treatment group [TNF-α (μg/L): 11.4±3.6 vs. 14.6±3.5, IL-1β (μg/L): 22.3±6.2 vs. 26.2±5.6, IL-10 (μg/L): 225.2±19.2 vs. 186.2±21.5, allP < 0.05]. In addition, compared with the routine treatment group, the total effective rate was higher [98.3% (60/61) vs. 90.0% (54/60),P < 0.05], and the incidence of sequelae was lower [1.64% (1/61) vs. 13.3% (8/60),P < 0.05] in TCM treatment group.Conclusion The Chaishi fever particles can effectively treat the patients with epidemic encephalitis B and the action is related to the inhibition of inflammatory reaction.

As tremendous genomic data avalanches, exploring biological mechanism by data analysis and theory methods has become important for theoretical biology research. This method is significant for the study of complex gene functions and gene networks. Bowers used higher order logic relationships to decipher protein network organization, which is a systemic method called logic analysis of phylogenetic profiles (LAPP). LAPP is a data modeling and different from traditional computational methods. This computational approach identifies logic relationships of the elements (or components) in complex networks through the logic analysis of their expression data. The method can be used to infer functional relationships of two associated proteins to one another. It is important for discovering the new function mechanism of the protein. The clusters of orthologous groups (COGs) involved in a gene network usually are large groups and therefore LAPP is also an approach for complex gene logic networks. After the establishment of the gene logic network, it is convenient for the regulation of gene through the network. The method can used in many fields, such as species evolution, oncologic diagnosis and so on. LAPP was systematically described and analyzed and recent developments in methodologies and applications were highlighted. Some opinions of them were also given.

Objective To establish a model of rat orthotopic liver transplantation and investigate the relationship among cold preservation time, activation of nuclear transcription factor-κB (NF-κB) and donor preservation injury after liver transplantation. Methods Orthotopic liver transplantation was performed in Wistar rats which were randomly divided into the following groups according to the different duration of liver cold storage in UW solution: group A (sham operation, n=10), group B NF-κB in liver before and after transplantation was measured by electrophoretic mobility shift assays; protein expression of tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) in the liver was measured by immunohistochemistry; the serum TNFα and IL-1β, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and hepatic cell apoptosis were examined. Results With extended cold storage duration, the activity of NF-κB in the donor liver increased (P<0.05, group D vs. groups A, B and C). TNF-α and IL-1β levels also increased (P<0.05, group D vs. groups A, B and C). Donor liver reperfusion injury was gradually aggravated with the prolonging of graft cold preservation. Both the serum TNF-α and IL-1β levels increased highly (P<0.05 group A vs. groups B, C and D),NF-κB in the liver significantly increased (P<0.05, group A vs. groups D, B and C) with gradual prolonging of graft cold preservation time. The serum ALT and AST level and apoptosis index level elevated greatly (P<0.05, group A vs. groups D, B and C). Conclusion NF-κB of donor liver was activated inductively in cold preservation phase and activated explosively in reperfusion phase. The longer cold preservation time was, the higher NF-κB level in donor liver became. NF-κB led to the expression of TNF-α and IL-1β in donor liver. Inflammatory factors are one of the most important mechanisms for the donor liver injury after liver transplantation.

The technique of liquisolid compress is a new technique developed in 1990s, which was considered to be the most promising technique to improve the dissolution of water-insoluble drugs. In this article, tanshinone II(A) and the extracts of the ester-solubility fractions were chosen as the model drugs to evaluate the effects of the liquisolid technique for enhancement of dissolution properties of tanshinone II(A). Several liquisolid tablets (LS) formulations containing different dosage of drugs and various liquid vehicle were pre-pared and for all the formulations, microcrystalline cellulose and silica were chosen as the carrier and coating materials to evaluate their flow properties, such as angle of repose, Carr's compressibility index and Hausner's ratio. The interaction between drug and excipients in prepared LS compacts were studied by differential scanning calorimetry(DSC) and X-ray powder diffraction (XRPD). The dissolution curves of tanshinone II(A) from liquisolid compacts were investigated to determine the technique's effect in improving the dissolution of tanshinone II(A) and its impacting factors. According to the results, the dissolution increased with the rise in the dissolution of the liquid-phase solvent. The R-value and drug dosage can significantly affect the drug release, but with less impact on active fractions. This indicated that liquisolid technique is a promising alternative for improvement of dissolution property of water-soluble drugs, and can make a synergistic effect with other ester-soluble constituents and bettern improve the release of tanshinone II(A). Therefore, the technique of liquisolid compress will have a better development prospect in traditional Chinese medicines.
