Cytokines play an important role in the genesis and development of tumor.Antitumor mechanisms of some cytokines are clearly testified.Currently,the main cytokines used in tumor clinical treatments are interferons,interleukins and tumor necrosis factors.For the lack of specificity,there are too many side effects for some patients to continue.So the application range of cytokines in tumor clinical treatment is limited.The most important measures to develop cytokines therapy are improving the stability of curative effect and reducing side effects.

Objective To improve the understanding of the characteristics of obstructive sleep apnea-hypopnea syndrome (OSAHS) in the elderly patients, and to improve the diagnosis and treatment level. Methods Monitoring results of polysomnography (PSG) from 110 elderly OSAHS patients were analyzed retrospectively. The general conditions, sleep architecture, apnea and hypopnea events, oxygen reduction as well as possible correlations between various indicators were analyzed using SPSS18.0 statistical software. Results The median rapid eye movement (REM) and non-REM (NREM) sleep time of elderly patients with OSAHS accounted for 2. 17% and 76.73%,respectively. The median arousal index was 45.6 times/h. The longest time of sleep apnea was (51.94±22.06) s, the median of average sleep apnea time was 22.50 s, the longest time of hypopnea was (47.06±12.52) s and the average hypopnca time was (21.50±4.63) s. The median respiratory disturbance index (RDI) of all patients was 21.50, the patients with RDI between 5 and 20 accounted for 46.40%, with RDI between 20 and 40 accounted for 31.80% and with RDI over 40 accounted for 21.8%. The average oxygen saturation accounted for (93.45% ± 2.81%), the lowest oxygen saturation accounted for (76.3%± 10. 5%) and the median oxygen desaturation index was 31.6;times/h. BMI was negatively correlated with lowest oxygen saturation (r=-0. 378, P＜0.01) and average oxygen saturation ( r = - 0. 355, P ＜ 0. 01 ), while was positively correlated with oxygen desaturation index (r=0. 338, P＜0. 01 ). The lowest oxygen saturation was negatively correlated with the longest time of obstructive apnea (r= -0. 47, P＜0. 01 ), the average time of obstructive apnea (r=-0.316, P＜0.01), the longest time of hypopnea (r=-0.293, P＜0.01) and the average time of hypopnea (r=-0. 277, P＜0.01). The median time intervals of oxygen desaturation during supine, left side and right side position were 2.36 min, 11.54 min and 12.45 min,respectively. The median time intervals of oxygen desaturation during left side and right side position were both longer than that of supine position (Z= -6.12 and -7. 10 respectively, both P＜0.01).Conclusions Elderly patients with OSAHS manifest obvious disorder of sleep structural and sleep fragmentation. According to RDI, the majority of the patients are classified as mild to moderate in severity. However, elderly patients with OSAHS are severe regarding to hypoxia relatively. The severity of hypoxia is related with BMI and the lasting time of sleep-disordered breathing events, and hypoxia are less severe when sleeping on left side or on right side.

This study was aimed to analyze the medication and herbal prescription rules in the treatment of nephrotic syndrome (NS) by Prof. Huang Chunlin with Traditional Chinese Medicine Inheritance Support System ( TCMISS ) . Prescriptions used for NS treatment were collected and the data was entered into the TCMISS . The commonly used herbs and herbal prescription rules in NS treatment by Prof. Huang were summarized through the association rules, revised mutual information, complex system entropy cluster and other unsupervised hierarchical clustering methods. The results showed that based on the analysis of 280 prescriptions from 68 patients, the fre-quency of each herb and association rules among herbs included in the database were identified. And the basic NS treatment prescription by Prof. Huang Chunlin and 8 new prescriptions were mined from the database. It was concluded that data mining is of great practical value to the summarization of clinical experiences of well-known TCM doctors.

OBJECTIVETo report the postmortem findings of a case of highly pathogenic H5N1 avian influenza virus occurring in human beings.

METHODSPostmortem examination was carried out in a deceased caused by highly pathogenic H5N1 avian influenza virus. Detailed light microscopy of major organs, including heart, lungs, liver, spleen, kidneys and brain, was performed. The lung tissue was further investigated by histochemistry, immunohistochemistry and electron microscopy.

RESULTSMajor histopathologic changes in lungs secondary to highly pathogenic H5N1 avian influenza virus included diffuse alveolar damage, hyaline membrane formation and focal hemorrhage. Some of the alveolar spaces contained lightly eosinophilic liquid, lymphocytes, macrophages, plasma cells and small number of neutrophils. Congested capillaries were commonly seen in the alveolar septa which were focally rimmed by hyaline membrane. Immunohistochemical study showed that the lymphocytes were mainly of T lineage and macrophages were also demonstrated.

CONCLUSIONSHighly pathogenic H5N1 avian influenza virus causes pathologic changes mostly in lungs, including diffuse alveolar damage and acute exudative changes (involving mainly T lymphocytes and macrophages). The resulting parenchymal destruction, consolidation, pulmonary edema and hemorrhage eventually lead to respiratory distress and death.

OBJECTIVETo objectively evaluate the clinical effect of traditional Chinese medicine in treating children's respiratory syncytial viral pneumonia (RSVP) of phlegm-heat blocking Fei syndrome (PHBFS).

METHODSA single-blinded multi-center, blocked, randomized and parallel-controlled method was adopted. The clinical study was carried out on 206 children with RSVP-PHBFS who were assigned to two groups, 108 in the test group treated through intravenous dripping of Qingkailing Injection () in combination of oral intake of Er'tong Qingfei Oral Liquid () and 98 in the control group with intravenous dripping of ribavirin injection in combination with oral intake of potassium guaiacol sulfonate oral liquid, all for 10 days. The clinical efficacy was evaluated and compared at the end of the trial from various aspects by three methods including comprehensive efficacy, post-treatment main symptoms score difference and survival analysis of the main symptoms.

RESULTSAfter treatment, in the test group, 60 patients were cured, 36 markedly alleviated, and 12 improved. In the control group, 41 were cured, 38 markedly alleviated, 18 improved and 1 unchanged. Comparison on the comprehensive efficacy between the two groups shows a better efficacy in the test group (chi(2)=4.4527, P=0.0348). Scores of the main symptoms were lowered after treatment in both groups, the difference was 22.41+/-4.99 scores in the test group and 17.61+/-6.34 scores in the control group, being more significant in the former (t=-5.99, P<0.01). Survival analysis shows that there was significant difference between the two groups in the effect initiating time on such symptoms as fever, cough, copious sputum, shortness of breath, and rales, which was earlier in the test group (P<0.01 or P<0.05).

CONCLUSIONEvaluation of the efficacy of traditional Chinese medicine in treating children with RSVP-PHBFS by using the three methods jointly could better show the objectivity of the evaluation.

BACKGROUNDSpine surgery using computer-assisted navigation (CAN) has been proven to result in low screw misplacement rates, low incidence of radiation exposure and excellent operative field viewing versus the conventional intraoperative image intensifier (CIII). However, as we know, few previous studies have described the learning curve of CAN in spine surgery.

METHODSWe performed two consecutive case cohort studies on pedicel screw accuracy and operative time of two spine surgeons with different experience backgrounds, A and B, in one institution during the same period. Lumbar pedicel screw cortical perforation rate and operative time of the same kind of operation using CAN were analyzed and compared using CIII for the two surgeons at initial, 6 months and 12 months of CAN usage.

RESULTSCAN spine surgery had an overall lower cortical perforation rate and less mean operative time compared with CIII for both surgeon A and B cohorts when total cases of four years were included. It missed being statistically significant, with 3.3% versus 4.7% (P = 0.191) and 125.7 versus 132.3 minutes (P = 0.428) for surgeon A and 3.6% versus 6.4% (P = 0.058), and 183.2 versus 213.2 minutes (P = 0.070) for surgeon B. In an attempt to demonstrate the learning curve, the cases after 6 months of the CAN system in each surgeon's cohort were compared. The perforation rate decreased by 2.4% (P = 0.039) and 4.3% (P = 0.003) and the operative time was reduced by 31.8 minutes (P = 0.002) and 14.4 minutes (P = 0.026) for the CAN groups of surgeons A and B, respectively. When only the cases performed after 12 months using the CAN system were considered, the perforation rate decreased by 3.9% (P = 0.006) and 5.6% (P < 0.001) and the operative time was reduced by 20.9 minutes (P < 0.001) and 40.3 minutes (P < 0.001) for the CAN groups of surgeon A and B, respectively.

CONCLUSIONSIn the long run, CAN spine surgery decreased the lumbar screw cortical perforation rate and operative time. The learning curve showed a sharp drop after 6 months of using CAN that plateaued after 12 months; which was demonstrated by both perforation rate and operative time data. Careful analysis of the data showed CAN is especially useful for less experienced surgeon to reduce perforation rate and intraoperative time, although further comparative studies are anticipated.

OBJECTIVETo analyze retrospectively the postoperative complications of acromioclavicular joint dislocation (Tossy III) and explore the preventative methods for the complications.

METHODSForty-eight cases of acromioclavicular joint dislocation (Tossy III) were reviewed, 14 cases treated with open reduction and Kirschner wire combined with steel wire fixation (group A), 11 cases treated with open reduction and lag screw or steel wires fixation (group B), 23 cases treated with open reduction and AO clavicular hook plate fixation (group C). The acromioclavicular ligament, articular capsule, coracoclavicular ligament and coracoacromial ligament were repaired in all patients. The reasons of postoperative complications were analyzed.

RESULTSForty-eight patients got average follow-up of 18 months. In group A, 8 patients obtained excellent results, 4 good and 2 poor; in group B, 7, 3 and 1, respectively; in group C, 21, 1 and 1, respectively. The excellence rate showed statistical difference between group A and C (P < 0.05). In group A, 4 cases with postoperative pain, 3 cases with periarthritis of shoulder, 3 cases with arthritides of acromioclavicular joint, 4 cases with internal fixation failure and 2 cases with recurrence of joint dislocation; in group B, 3, 2, 1, 3 and 1, respectively; in group C, 22, 2, 1, 2 and 1, respectively. There was no significant difference in postoperative complications in three groups (P > 0.05).

CONCLUSIONSelection of the suitable internal fixation and reconstruction of coracoclavicular and coracoacromia ligaments is the basic operation. Acromioclavicular space debridement, ligamentous reconstruction, rigid internal fixation are effective methods to reduce postoperative complications for the treatment of acromioclavicular joint dislocation.
