OBJECTIVE:To provide reference for strengthening the cultural construction and promoting the cultural develop-ment of TCM in Chongqing. METHODS:Questionnaire was adopted to investigate the status quo and cognition of some citizens, staffs in medical and health institutions for the cultural construction of TCM in public TCM medical and health institutions above Grade Two in Chongqing,and the data was statistically analyzed. RESULTS:Totally 45 questionnaires were sent out for TCM med-ical and health institutions,45 were effectively received with effective recovery of 100%;3 500 were sent out for the citizens,2 250 were effectively received with effective recovery of 64.29%;1 100 were sent out for the staffs in TCM medical and health institu-tions,702 were effectively received with effective recovery of 63.82%. In terms of cultural construction in surveyed institutions,or-ganization,principles and unit markings carried out a relatively high proportion in the core cultural soft power construction,the de-velopment of behavioral norms system carried out a relatively low proportion;and the proportion was higher in the hardware envi-ronment construction. In terms of the cognition of surveyed citizens for the TCM culture,62.98% believed in TCM;the first rea-son for choosing TCM was its less side effects(24.76%);89.42% thought it was necessary to keep in good health. In terms of the cognition of surveyed staffs for the cultural construction of TCM,81.91%thought the TCM culture was taken seriously in their hos-pital;60.54% showed great satisfaction with the cultural construction of TCM;only 23.08% was very familiar with the concept of TCM core values;the surveyed staff thought the main problems in the cultural construction of TCM were lack of facilities (69.09%)and talent personals(44.59%). CONCLUSIONS:The organization,principles,unit markings and facilities in Chongq-ing TCM medical and health institutions are taken seriously,while the behavioral norms system needs to be strengthened;the citi-zens’cognition for TCM culture should to be improved,as well as the staffs’TCM cultural awareness in TCM medical and health institutions.

Objective To observe the expression of aquaporin-7 (AQP-7)during the development of renal tubules of mice,and investigate the relationships between AQP-7 and renal tubule development.Methods Kidneys were selected from mice at embryonic days(E)12,14,17,and 18 and postnatal days(P)1,3,7,14,24,40 and 70.The expression of AQP-7 was observed by immunohistochemical(IHC)method in renal tubules.The surface area density values of AQP-7 positive expression were measured by stereological method while the content variation of AQP-7 in the renal tissue of mice was examined by Western blot.Results IHC analysis showed that AQP-7 was expressed in developing renal tubules at the proximal tubule at E14 day,localized along the brush border of the proximal straight tubules (S3 segment)where the cortex and outer medullalie after P14 d,but AQP-7 was not observed in the nephrogenic zone or inner medulla.The results of stereology discovered that the surface area density values of AQR-7 had increased gradually in the apical of renal tubule and reached the maximum at P24 d and then remained stable with the growth of mice.Western blot indicated that AQP-7 expression in kidneys had reached the peak at P24 d and remained stable.Conclusion The expressions of AQP-7 in the developing renal tubules of mice show a chronological and spatial sequence,which plays an important role in water and glycerol balance of mouse kidneys at the late stage of development.

Objective To investigate whether the percutaneous ethanol injection (PEI)under sedation and analgesia can in-crease the energy deposition and curative efficiency of the high intensity focused ultrsound(HIFU)in treating unresectable middle and advanced stages of primary liver cancer.Methods Thirty-six cases of clinically diagnosed unresectable middle and advanced sta-ges of primary liver cancer were randomly divided into the PEI+ HIFU group(combination group,n = 23)and the simple HIFU group (HIFU group,n=13);10mL of the mixture of 99.7% ethanol and iodized oil (9:1)was given by intratumoral injection at 30 min before ablation in the PEI+HIFU group,while 0.9% physiological saline 10mL was replaced in the simple HIFU group.The ablation energy efficiency factor(EEF)and irradiation time were compared between the two groups.Results The ablation EEF in the PEI+HIFU group and the simple HIFU group were (13.82+4.26)J/mm3 and (25.63+6.31)J/mm3 respectively,the PEI+HIFU group was significantly lower than the simple HIFU group (P <0.05);the irradiation time were (1 468.28+253.21)s and (2 352.56+463.34)s respectively;which in the PEI+ HIFU group was significantly shortened (P <0.05).Conclusion PEI can enhance the HIFU ablation energy deposition and improve the efficiency of HIFU for treating unresectable primary liver cancer.

OBJECTIVETo investigate the clinical value of intraoperative ultrasonography in cervical laminoplasty.

METHODSThirty patients underwent cervical laminoplasty for cervical compressive myelopathy in our hospital from April 2010 to April 2012. Spinal cord compression ratio was calculated in preoperative MRI axial images for every patient. The spinal cord decompression status was evaluated by intraoperative ultrasonography during cervical laminoplasty. The pre- and post-operative Japanese Orthopaedic Association Scoring System (JOA) score was recorded, and the recovery ratios of surgery were graded using the Hirabayashi equation. The relationship between the parameters and neural recovery was explored.

RESULTSThe intraoperative ultrasonography was used to evaluate the ventral compression of the spinal cord. The ultrasonographic dynamic viewings were classified into three types based on the spinal cord contact with ventral structures after decompression: Type 1, non-contact (n=2); Type 2, contact and apart (n=16); and Type 3, contact (n=12). The patients were divided into two groups: group A, showing Type 1 or 2 findings, representing satisfied decompression; and group B, showing Type 3 findings with insufficient decompression. The recovery ratio was (73.3±21.0)%(31.3%-100.0%) in group A, but decreased to (43.2±33.1)%(0-83.3%) in group B(t=3.05,p=0.005). Pearson analysis showed that the patient age(r=-0.294,p=0.122), preoperative JOA score(r=0.059,p=0.759), and spinal compression ratio(r=0.269,p=0.151) was not correlated with Hirabayashi recovery ratio.

CONCLUSIONIntraoperative ultrasonography during laminoplasty is a feasible and promising method for evaluating spinal cord decompression status and predicting the prognosis following surgery.

OBJECTIVETo study whether Danggui Shaoyao Powder (DSP) is by way of improving pineal function to realize its anti-aging effects.

METHODSForty aged rats were randomly divided into the sham operated group (A), the pinealectomized group (B), the sham medicated group (C), the pinealectomized and medicated group (D). The medication given was gastric perfusion of DSP for 3 weeks. Learning and memory ability of rats was observed using Morris water maze and the serum melatonin (MLT) concentration of the rats was measured by radio-immunoassay.

RESULTSThe average escape latency in Group B was significantly longer than that in other groups (P <0.05). The times of passing through the platform and the percentage of swimming distance in Group C were significantly higher than those in other groups (P <0.05). The serum MLT was higher at daytime than at night in Group C and D (P <0.05); that at daytime in Group C was higher than Group A (P <0.05) and also higher in Group D than Group B; that at daytime was higher in Group C than Group D; that at night markedly decreased in Group D as compared with Group B (P <0.05).

CONCLUSIONDSP could increase the melatonin secretion and improve learning and memory ability. Since its effects reduced after pinealectomy, it could be deduced that improving pineal function should be one of the action mechanisms for anti-aging.

BACKGROUND:Pedicle screw is the major instrumentation of surgery in thoracic spine. However, there have been few reports about pedicle morphology relevant to screw insertion tracts, and few reports comparing the normal adolescents and adolescent idiopathic scoliosis patients. OBJECTIVE:To compare the morphologic characteristics of the thoracic pedicle with regard to safe thoracic pedicle screw placement in normal adolescents and adolescent idiopathic scoliosis patients. METHODS: Thoracic pedicles of thirty-five normal adolescents and thirty-five adolescent idiopathic scoliosis patients were measured with three-dimensional reconstruction CT images. Measured parameters include (1) critical distance: the shortest distance from an entry point to the ventral cortex of the lamina. (2) Safe distance: the distance from the entry point to the tangent of the spinal canal at the medial wal of the pedicle. (3) Pedicle screw length. (4) Pedicle width. (5) Pedicle transverse angle. The dangerous area was defined as the distance between the critical distance and the safe distance. RESULTS AND CONCLUSION: The mean critical distance was (9.2±1.0) mm for the normal adolescents, and (9.4±1.2) mm for the adolescent idiopathic scoliosis patients. Safe distances were significantly less in normal adolescents (14.7±0.8) mm than that of the adolescent idiopathic scoliosis group (15.4±1.4) mm (P < 0.001). The dangerous area was (5.4±0.7) mm for the normal adolescents, which was significantly less than that of the adolescent idiopathic scoliosis patients (6.0±1.0) mm (P < 0.001). Pedicle screw length was (36.6±4.1) mm for the normal adolescents and (37.1±5.3) mm for the adolescent idiopathic scoliosis patients. Pedicle width was (5.8±1.2) mm for the normal adolescents and (5.7±1.7) mm for the adolescent idiopathic scoliosis patients. No significant difference in critical distance, pedicle screw length and pedicle width was found between the two groups (P=0.382, 0.135, 0.293). Pedicle transverse angle decreased gradualy from T1 to T12 in both groups. These results verify that pedicle morphology of many parameters is different between normal adolescents and adolescent idiopathic scoliosis patients, especialy in the apical area of the thoracic curve.

Objective To explore the diagnostic significance of CT and MRI in dermatofibrosarcoma protuberans.Methods Analyze the CT and MRI images of 16 cases which were confirmed as dermatofibrosarcoma protuberans by pathology.The medical imaging features of dermatofibrosarcoma protuberans were summarized.In the total 16 cases(including 6 male cases,10 female cases),15 cases had suffered from dermatofibrosarcoma protuberans for more than 1 year, 11 cases for more than 5 years, and 9 cases had history of recurrence.Results On MRI, the mass was slightly hypointense on T 1 WI, inhomogeneously hyperintense on T 2 WI with inhomogenous enhancement.The diameters of mass were less than 5 cm in 3 cases,and were more than 5cm in 13 cases.Fifteen cases had clear demarcation between the masses and their adjacent muscles , 7 cases had “suspension sign” in shapes, 10 cases had “sub-nodules outward” features at the edge of the tumors , 12 cases had “multinodular” features inside the tumor , and 8 tumors grew into the surrounding fat layer like roots.Conclusion Dermatofibrosarcoma protuberans can be diagnosed accurately based on the features displayed on CT and MRI.

Background and purpose: MicroRNAs (miRNAs) play an important role in tumor biological behavior. miRNAs are down-regulated or up-regulated in various cancer types, triggering abnormal cell differentiation, proliferation and apoptosis. This study was designed to investigate the expression and clinical signiifcance of miR-187*in colorectal cancer (CRC), and further to investigate its roles in promoting cell apoptosis. Methods:The expressions of miR-187* in 40 CRC cases were examined by real-time quantitative reverse transcription-PCR (qRT-PCR). The relationship between miR-187*expression and clinical features of CRC was analyzed. HCT116 cells were transfected with a miR-187*mimic and the apoptosis of the transfected cells were examined by lfow cytometry (FCM). Results:The expression of miR-187*was down-regulated in CRC tissues 0.165 (0.106, 0.428) compared with those in normal tissues 0.334 (0.211, 0.712) (P<0.05), especially in mucinous carcinoma and older age CRC (P<0.05). Transfection of HCT116 cells with a miR-187*mimic up-regulated the expression of miR-187*and increased cell early apoptosis (P<0.05). Conclusion: The expression level of miR-187* was lower in CRC. miR-187* expression correlates with histological type and age. Transfection of HCT116 cells with a miR-187*mimic accelerates apoptosis of tumor cells, suggesting that miR-187*is a potent tumor suppressor.
