OBJECTIVETo evaluate the efficacy of Chinese medicine (CM) combined adjuvant chemotherapy in postponing relapse and metastasis of radical resected Ib-IIIa stage non-small cell lung cancer (NSCLC) patients, and to explore its effect in improving their quality of life (QOL) and clinical symptoms.

METHODSWe designed a cohort study of 336 radical resected Ib-IIIa NSCLC patients by analyzing disease free survival (DFS) using Log-rank test. They were randomly assigned to the control group (155 cases, treated by adjuvant chemotherapy group) and the test group (181 cases, treated by adjuvant chemotherapy combined CM). By using controlled method, 60 radical resected NSCLC patients undergoing NP/NC program in 2012 (vinorelbine 25 mg/m2, combined with cisplatin 75 mg/m2 on day 1 and day 8/on day 1 or on day 1, 2, and 3; or carboplatin AUC = 5 on day 1) were assigned to the control group (29 cases) and the test group (31 cases). QOL scores (using EORTC QLQ-LC43 questionnaire) and TCM symptoms scores were compared between the two groups before chemotherapy, peri-chemotherapy (one day before the 2nd course of chemotherapy) , and after chemotherapy (20 days after ending the 4th course of chemotherapy).

RESULTS(1) The median DFS was longer in the test group than in the control group, but with no statistical difference between the two groups (42.73 months vs 35.57 months , P = 0.179). In the subgroup analysis, there was statistical difference in IIIa stage DFS. The median IIIa stage DFS of was longer in the test group than in the control group with statistical difference (27.87 months vs 19. 93 months, P = 0.047). (2) In the control study, repeated measured data indicated there was significant difference in physical functions between the two groups (P < 0.05). Total scores for health states decreased more in the test group than in the control group, but with no statistical difference (P > 0.05). Scores for constipation and CM syndrome scores were higher in the test group than in the control group (P < 0.05).

CONCLUSIONSCM had advantages in postponing DFS of radical resected NSCLC patients, especially in IIIa stage. CM could improve their QOL and clinical symptoms during adjuvant chemotherapy.

OBJECTIVE: To explore the pathogenetic mechanism of cystic meningioma and the key to its diagnosis and operation. METHODS: Clinical data of 8 patients with cystic meningioma were analyzed retrospectively. The occuring position and cure rate of cystic meningioma were compared with those of solid meningioma in the corresponding period. RESULTS: All patients were subjected to total resection of tumor parenchyma and cystic wall. No operative death and severe complications occurred. The incidence of uppertentorial region of cystic meningioma was higher than that of solid meningioma, and the difference was significant (χ(2)=2.618, P<0.05). The cure rate was not significantly different between cystic meningioma and solid meningioma (χ(2)=0.010, P>0.05). CONCLUSION Removing tumor totally is the key to preventing its recurrence.

Objective To evaluate the association of prostate volume, PSAD and F/T with prostate cancer detection rate in males with a total PSA of 4?10 μg/L. Methods Clinical data of 196 patients who underwent prostate biopsy from November 2006 to September 2010 and with a PSA of 4?10 μg/L were retrospectively analyzed. The association of detection rate of prostate cancer with prostate volume, prostate specific antigen density PSAD) and free PSA/total PSA ratio ( F/T) was analyzed by Spearman coefficient, receiver operating characteristic curve and logistic regression analysis. Results The prostate volume, PSAD and F/T had a significant association with detection rate of prostate cancer ( P<0.05 for all) . The odd ratio was 0. 96, 1. 91 and 0. 02, respectively. The area under curve ( AUR ) was 0. 31, 0. 66 and 0. 63, respectively. The cancer detection rate was decreased along with the increase of prostate volume. When PSAD 0.15 ng·ml-1·ml-1 was used as the cut?off value, the sensitivity, specificity, positive prediction rate and negative prediction rate was 72. 3%, 51. 1%, 42. 3% and 21. 2%, respectively. When the patients were divided by prostate volume into <19. 9, 20?39. 9, 40?59. 9, 60?79. 9 and >80 ml subgroups, the cancer detection rate of each subgroup was 50.0%, 45.6%, 30.8%, 15.4% and 5.6%, respectively. Conclusion In patients with a total PSA of 4?10μg/L, the prostate cancer detection rate has a significant association with prostate volume, PSAD and F/T.

OBJECTIVETo compare the surgical results of two kinds of posterior approach for osteoporotic thoracolumbar Kvmmell's disease.

METHODSClinical and radiographic results of 1-segmental pedicle screw fixation combined with vertebroplasty (Group A, n equal to 12) or posterior shortening osteotomy (Group B, n equal to 16) for osteoporotic thoracolumbar Kvmmell's disease were analyzed retrospectively. Japanese orthopedic association (JOA) and visual analogue scale (VAS) scores were used for clinical evaluation. Neurological status was judged by Frankel grades. X-ray was used to evaluate the radiographic results. Complications related to operation and devices were also considered.

RESULTSThe follow-up period was 12-54 months (average 29 months). Pre-and post-operative VAS were 9.3 and 3.2 in Group A, 8.9 and 2.5 in Group B, respectively. The mean JOA score at the final follow-up was significantly higher than that of pre-operation (t equal to 5.306, P less than 0.001). There was no significant difference between Groups A and B (t equal to 0.618, P larger than 0.05). The kyphosis were corrected from preoperative 33.9 degree A)/37.3 degree B) to postoperative 10.3 degree A)/6.5 degree B), and 15.3 degree (A)/13.7 degree B) at the final follow-up. There was a significant difference between the two groups at the final follow-up. Frankel grade was improved from grade C preoperatively to postoperatively grade D or E in 7 cases of Group A and 5 cases of Group B, from grade D to E in 5 cases of Group A and 11 cases of Group B. The mean improvement was 1.6 and 1.7 grades for Groups A and B, respectively. There were no serious complications related to internal fixation.

CONCLUSIONSThe similar clinical results can be obtained by the two kinds of posterior surgical methods for osteoporotic Kvmmell's disease. Posterior spinal shortening is a better choice for patients with serious kyphosis combined with neurological deficit than the other.

Objective To investigate the correlation between cognitive development and levels of dopamine(DA) and 3,4-dihydroxyphenylacetic acid(DOPAC)in the hippocampus of 80-day-old neonatal rats born of fear-impaired pregnant rats. Methods The pregnant rat model of fear-impaired kidney was established by watching other rats shocked with electricity. The cognitive development of the neonatal rats was assessed by Morris water maze test at 80 days after birth. The brain microdialysis samples of the right hippocampus were collected using a stereotaxic instrument, and the levels of DA and DOPAC were determined by HPLC-ECD. Results Compared with the control group, the mean escape latency of the 80-day-old neonatal rats in the model group was increased. Their swimming speed was slower. The 20% time spent in the peripheral zone became longer, and the frequency of platform crossing was decreased, showing significant differences(P< 0.05). The levels of DA and DOPAC in the extracellular fluid of the hippocampus of the 80-day-old neonatal rats in the model group were decreased at each time points of perfusion, showing a significant difference(P <0.05). The level of DA, a kind of monoamine neurotransmitter in the hippocampus, was positively correlated with the mean escape latency,the frequency of passing the platform of the 80-day-old rats,while was negatively correlated with the 20% time spent in the peripheral zone, with a significant correlation(P < 0.05). In addition, there was a positive correlation between the DOPAC level and the mean escape latency, the frequency of passing the platform(P< 0.05). Conclusions Fear-impaired pregnant rats can affect the spatial learning and memory ability of their 80-day-old neonatal rats,with reduction in the levels of DA and DOPAC in the hippocampus, which is closely correlated with the cognitive development of the neonatal rats.

Background: and Purpose Intracranial vertebrobasilar atherosclerotic stenosis (IVBAS) is a major cause of posterior circulation stroke. Some patients suffer from stroke recurrence despite receiving medical treatment. This study aimed to determine the prognostic value of a new score for the posterior communicating artery and the P1 segment of the posterior cerebral artery (PCoA-P1) for predicting stroke recurrence in IVBAS. Methods: We retrospectively enrolled patients with severe IVBAS (70%–99%). According to the number of stroke recurrences, patients were divided into no-recurrence, single-recurrence, and multiple-recurrences groups. We developed a new 5-point grading scale, with the PCoA-P1 score ranging from 0 to 4 based on magnetic resonance angiography, in which primary collaterals were dichotomized into good (2–4 points) and poor (0 or 1 point). Stroke recurrences after the index stroke were recorded. Patients who did not experience stroke recurrence were compared with those who experienced single or multiple stroke recurrences. Results: From January 2012 to December 2019, 176 patients were enrolled, of which 116 (65.9%) had no stroke recurrence, 35 (19.9%) had a single stroke recurrence, and 25 (14.2%) had multiple stroke recurrences. Patients with single stroke recurrence (odds ratio [OR]= 4.134, 95% confidence interval [CI]=1.822–9.380, p=0.001) and multiple stroke recurrences (OR=6.894, 95% CI=2.489–19.092, p<0.001) were more likely to have poor primary collaterals than those with no stroke recurrence. Conclusions The new PCoA-P1 score appears to provide improve predictions of stroke recurrence in patients with IVBAS.

OBJECTIVETo investigate the effect of active components of Danshen and Shanzha of different matching proportions on atherosclerosis (AS), in the expectation of obtaining the optimum combination method.

METHODAtherosclerotic rats were fed with high fat diet, and injected with vitamin D3 and ovalbumin. Aqueous extracts of Danshen (DSA) and Shanzha (SZA) and lipophilic extracts of danshen (DSL) were adopted for a low, medium and high-dose orthogonal experiment, to observe the effect of their different matching proportions on lipid level, oxidative stress, endothelial function and inflammatory reaction. The principal component analysis and cluster analysis were adopted for the multi-objective optimization of experimental results.

RESULTCompared with the model group, all of samples with different proportions of DSA, DSL and SZA showed effect in lowering lipid level, scavenging free radicals, reducing endothelial dysfunction and inhibiting inflammation. According to the variance analysis, DSA2-SZA2-DSL1, DSA3-SZA2-DSL1, DSA3-SZA3 -DSL3 and DSA3-SZA1-DSL1 were the optimal proportions for lowering lipid level, scavenging free radicals, reducing endothelial dysfunction and inhibiting inflammation, respectively. According to the results of the multi-objective optimization, DSA2-SZA1-DSL2 was the optimal proportions of anti-AS.

CONCLUSIONAll of active components of Danshen and Shanzha of different matching proportions show the anti-AS effect in rats to varying degrees, but with different focus in different matching proportions.
