Objective To explore the guiding value for operation of MRI in diagnosing the cranial base chordoma. Methods MRI features of 15 cases with cranial base chordoma, which were proved by biopsy and surgery, were retrospectively analyzed. Results Most of the cranial base chordoma were located in the middle area of the skull base such as clivus and sellar region and always invaded extensively the nerves and major intracranial vessels of skull base. All tumors were hypointense on T_2WI and enhanced more markedly, but steady heterogeneous. Conclusion MRI examination is of great clinical signifiance in delineating the location, size and extension of cranial base chordoma, and showed anatomic relation with surrounding structures such as the major intracranial vessels of skull base, which is very important in surgical planning.

Conclusion Satisfatory results were obtained with the average recovery ratio of 99.76% ,RSD 2.27%.

Objective To investigate the trend of the national Kaschin-Beck disease condition, and provide the scientific basis for the government to make preventing strategy. Methods The data were collected from national surveillance on Kaschin-Beck disease(KBD) condition from 2000 to 2007 by restrospective method. The national X-ray detective rates and KBD condition in the eastern and western areas of China were analyzed. Results Monitoring data were collected from 189 monitoring points in 14 provinces of China, and 21 287 X-ray films were photographed of right hands of children from 2000 to 2007. X-ray detective rate was decreased significantly of national KBD from 2000 to 2007. The condition in the west of China is slightly more serious than the eastern areas, but the average of X-ray detective rate was also decreased from 21.75% to 7.30%. National condition is basically controlled. X-ray detective rate had been controlled below 5%, exept for Qinghai, Tibet and Inner Mongolia and so on. Conclusions Ninty percent of the wards have reached the controlled level according to the X diagnosis standard. In terms of the severity of the disease, most of the wards are occupied by patients with slight condition, 10% ward with moderate condition, less than 1% ward with serious condition.

OBJECTIVETo study the predicting effect of proly 4-hydroxylase beta polypeptide (P4HB) in treating non-small cell lung cancer (NSCLC) patients by Yiqi Chutan Recipe (YCR).

METHODSTotally 46 stage III and IV NSCLC patients were treated by YCR for 4 therapeutic courses. Effect was assessed by RECIST of solid tumor. P4HB expression was detected in the lung cancer tissue by immunohistochemical assay. Factors affecting disease control rates (DCR) of YCR were analyzed by Logistic regression analysis. The correlation between P4HB expression and the effect of YCR was analyzed.

RESULTSThe DCR of advanced NSCLC treated by YCR was 36.96% (17/46 cases). P4HB was high expressed in advanced lung cancer tissue (6/15 cases). Gender, initial treatment, and retreatment are independent factors for affecting DCR of treating lung cancer by YCR.

CONCLUSIONP4HB might be taken as a factor for predicting the effect of YCR in treating NSCLC.

OBJECTIVETo explore the differences of electroacupuncture (EA) on onset time and symptom improvement for treatment of different types of functional constipation.

METHODSThirty-eight cases of constipation were selected, including 9 cases of constipation-predominant irritable bowel syndrome (IBS-C), 10 cases of slow transit constipation (STC), 10 cases of pelvic floor dyssynergia (PFD) and 9 cases of inadequate defecatory propulsion (IDP). The electroacupuncture was applied at Tianshu (ST 25), Fujie (SP 14), Shenshu (BL 23), Dachangshu (BL 25) and so on in abdominal and lumbosacral area, 5 times per week, 10 times as a treatment course. The onset time, score of clinical symptoms of constipation and improvement of every symptom in each group were compared.

RESULTS(1) The onset time was (1.78 +/- 0.83) days in IBS-C type, (3.11 +/- 1.90) days in IDP type, (4.10 +/- 1.85) days in STC type and (4.30 +/- 2.00) days in PFD type, indicating statistical differences between IBS-C type and STC type, IBS-C type and PFD type (both P < 0.05). (2) Compared before the treatment, the total scores of symptoms on the onset day in each group were all improved (P < 0.05, P < 0.01), and score of IBS-C type was superior to the rest 3 types (P < 0.05, P < 0.01). (3) EA improved desire to defecate or frequency of defecation in each type (P < 0.05, P < 0.01), in which both were improved in STC type and PFD type, and the improvement of defecation frequency was more significant in STC type (P < 0.01). EA relieved unsmooth defecation or pendant-expansion feeling in each type (all P < 0.05), in which both were improved in IBS-C type (both P < 0.05). EA relieved abdominal distension and pain in IBS-C type, STC type and PFD type (all P < 0.05), while its effects were not obvious on defecation difficulty, defecation time and defecation texture (all P > 0.05).

CONCLUSIONThe electroacupuncture for treatment of 4 types of constipation is characterized by rapid onset; the improved symptoms are not identical in the electroacupuncture treatment plan for each type of defecation; the main improvement of symptoms are lied on desire to defecate and frequency of defecation, unsmooth defecation or pendant-expansion feeling and abdominal distension and pain. Meanwhile the improvements of defecation texture, defecation difficulty and defecation time were not signi-ficant.

Objectives To investigate the effect of matrine (MAT) on adriamycin (ADR) induced podocyte injury in vitro and explore the function of the mammalian target of rapamycin (mTOR) protein signaling pathway during the intervention. Methods ADR (1μmol/L) was used to induce the model of podocyte injury and then the podocytes were intervened by 10, 20 and 40μg/ml MAT for 24 hours. The viability and apoptosis rate of podocytes, mRNA and protein expressions of desmin and mTOR were detected. The effect of different concentrations of MAT on ADR-induced podocytes was analyzed. Results Com-pared with the control group, declined viability of podocytes (P<0.001), increased percentage of apoptotic podocytes (P<0.001), and increased expression of damage marker desmin (P=0.002) were observed in ADR group. In ADR group, after intervention with MAT of 10-40μg/ml, increased viability of podocytes (P<0.05), decreased percentage of apoptotic podocytes (P<0.05), and decreased expression of damage marker Desmin were found (P<0.05). The protein expression of mTOR and phosphorylation state of mTOR (p-mTOR) decreased in ADR induced-podocytes (P<0.05), and after intervention with MAT of 10-40μg/ml, the expression of mTOR and p-mTOR increased (P<0.05). The expression of mTOR downstream target protein s6k1 and 4EBP1 mRNA decreased in ADR group (P=0.071), while increased after intervention with MAT of 10-40μg/ml (P<0.05). Conclusions 10-40μg/ml MAT have protective effects on ADR-induced podocytes in vitro. The protection mechanism may be related to mTOR signaling pathway.
