Wuyi is one of the Chinese medicine recorded in Shennong's Herbal Classic and many other herbal books during the long history period. Up to now, Wuyi is still an important medicine used for insecticidal and removing food retention. Recent researches indicated that Wuyi also had the function of anti-malaria and treating herpetic simplex keratitis. Therefore, Wuyi had notable value on clinic and development of new medicine. The herbalogical textual research on Wuyi was conducted through investigation of the literature of materia medica during the long historical period from Han Dynasty. It was demonstrated by this work that the original plants of Wuyi include Ulmus macrocarpa Hance and Hemiptelea davidii (Hance) Planch, in which, U. macrocarpa was the quality specie. U. pumila was the false specie which cause confusing. The medicine Wuyi was the processed product made from the nutlet of the plants through fermentation with other additive agents.

The achievement of Qimin Yaoshu in the area of herbalogical textual research was illustrated in this paper. Qimin Yaoshu quoted and keeped many contents from ancient agriculture books related in herbalogical literature. It also recorded the information of lots of tropical and subtropical plants. The author bringed forwarded many experiences indistinguishing plants and clarified some long last confused or wrong opinions. The studying philosophy and methods of the authors gave us much enlightenment in our herbalogical textual research. It should be taken into account when the herbalogical textual research was carried out.

The achievement of Nongzheng Quanshu in area of herhalogical textual research was illustrated in this paper. Nongzheng Quanshu recorded the information of 159 kinds of cultivated plants and 473 kinds of wild plants. It also quoted many contents from lots of ancient agriculture hooks related in herbalogical literature. Many agriculture researchers were encouraged to have done much work in area of herhalogical textual research It also included the materia medica hook Jiuhuang Bencao and Yecaipu therein and promoted their delivery.

Objective To investigate the expression of homeobox gene MSX-2 during cranial suture fusion of SD rats and discuss its significance. Methods SD rats aged 1, 2, 5, 8, 12, 15, 18, 22, 30 and 45 days were selected, and immunohistochemistry and Real-time PCR were employed to localize and quantify the expression of MSX-2 in different regions of cranial sutures. Results MSX-2 expressed in calvarial suture tissues including the extreme ends of the osteogenic fronts and the underlying dura mater. The expression of MSX-2 was low in posterior frontal suture (PF) and sagittal suture (SAG) from postnatal day 1 to day 8 before the initiation of suture fusion, while it was higher in PF than in SAG from postnatal day 12 to day 22 after the initiation of PF suture fusion. The expression of MSX-2 significantly declined in PF and was moderately higher than that in SAG from postnatal day 30 to day 45 after the initiation of suture fusion. Conclusion There is different expression of MSX-2 in PF and SAG during different suture fusion periods, which suggests the expression of MSX-2 may participate in the regulation of cranial bone development and the fusion of cranial sutures.

OBJECTIVETo evaluate the effect of Shexiang Baoxin Pill (SBP) on coronary vasodilation by analysis of coronary angiography (CAG).

METHODSA consecutive cohort of 300 patients who underwent CAG between January 2013 and July 2013 were recruited and randomly assigned to 2 groups before operation. Patients in the SBP group sublingually took SBP, while those in the control group sublingually took placebos. All patients repeatedly underwent CAG 5 min after administration. The vascular diameter was calculated by quantitative angiography analysis method. The diameter of the left anterior descending coronary artery was measured in patients whose coronary arteries had no stenosis. The narrowest vascular diameter was measured in patients whose coronary arteries had stenosis. The heart rate, blood pressure, and the vascular diameter were compared between before and after administration in the two groups.

RESULTSIn the two groups, there was no significant difference in changes of heart rate, systolic pressure, or diastolic pressure between before and after administration (all P > 0.05). There were 64 patients with normal CAG in the two groups, 30 in the control group and 34 in the SBP group. CAG showed there were 236 patients with stenotic coronary artery, 110 in the control group and 126 in the SBP group. The vascular diameter was obviously larger in patients in the SBP group with normal or abnormal CAG after administration (all P < 0.01). It was also obviously larger than that of the control group after administration (P < 0.05, P < 0.01).

CONCLUSIONSBP could dilate both normal coronary artery and lesioned coronary arteries, but did not lead to fastened heart rate and decreased blood pressure.

OBJECTIVE To explore the indication and effect of primary repair of the defects for stomal recurrence after total laryngectomy. METHODS A total of 18 cases with stomal recurrence after total laryngectomy were performed operation.The defect of hypopharynx and cervical oesophagus was repaired with free forearm flap (n=5),free jejunual interposition(n=3),pectoralis major myocutaneous flap (n=1)and pharyngogastric anastomosis(n=2).The defect of skin was repaired with pectoralis major myocutaneous flap.RESULTS All pectoralis major myocutaneous flaps were viable. Pharyngeal fistula occurred in 4 cases,one of whom had been performed free jejunual interposition,2 had been performed free forearm flap,and one with fistula bleeding had been performed pharyngogastric anastomosis.All cases could swallow after operation. During follow-up for 6 to 74 months,swallow obstruction occurred in 3 cases.CONCLUSION The methods of repair for surgical defect of stomal recurrence after total laryngectomy should depend on the bound of stomal recurrence and therapeutic procedure of primary tumor.

OBJECTIVE: To analyse the risk factors involved in local failure following radiotherapy and chemotherapy to nasopharyngeal carcinoma. METHOD: A retrospective analysis was carried out to review the histopathological data from 308 NPC patients who recieved medical treatment between 2004 and 2006. The incidence and the risk factor for local treatment failure were evaluated in a model that included the following factors: sex, age, T and N staging, histological grade of primary tumor, presence of cervical lymph node metastasis, size and laterals of positive neck nodes, levels involved, ways of radiation and condition of concurrent chemotherapy. Univariate chi2 test and multivariate stepwise logistic regression model were used for the analysis. Statistical analysis of survival of patients with local residues and recurrence was performed using Kaplan-Meier method. RESULT: Ninty-three cases (30.2%) presented local residues and recurrence in 308 patients of nasopharyngeal carcinomas. In the univariate analysis, it was confirmed that the following variables correlated to local failure, i. e., T staging (P < 0.01), N staging (P < 0.01), presence of cervical lymph node metastasis (P < 0.05), size and laterals of positive neck nodes (P < 0.05, respectively). In the multivariate analysis, the most ignificant risk factors for local failure were the T staging only. Kaplan-Meier analysis showed that overall survival rates of 71 NPC patients with local residues and recurrence who received re-treatment were 77.2% at 1 year, 40.4% at 3 years, 22.4% at 5 years, respectively. CONCLUSION T staging is the key risk factors in determining the development of local failure following radiotherapy or chemotherapy in NPC patients. Patients with primary tumor infiltrating bone have the higher risk of developing local residues and recurrence. Retreatment to the patients suffering from local failure can imrove survival rates.

Objective To analyse the features of vertebral hemangioma and inaging diagnostic value of vertebral hemangioma.Methods There were 14 cases with hemangioma proved by clinic and pathology.X-ray plain was performed in all cases,of which 9 cases were performed by CT scan and,only 6 cases were taken MR,and 2 cases had both CT and MR scan.Results The tumors were located in thoracic spine in 10 cases,in lumbar spine in 3 cases and in cervical spine in 1 case.8 cases showed typically fence-like or nest-like;the verterea were irregularly destroyed in 5 cases,of which 2 cases were associated with vertebrea collapsing.According to the features in plain film and CT scan,there were 2 cases misdiagnosed,but 6 cases were all made a correct diagnosis on the base of MR before surgry.Conclusion Typical vertebral hemangima can be diagnosed correctely according to plain film or CT while MR plays an important role in atypical cases.
