Journal of Practical Stomatology 1995;0(04):-
Objective:To test the periodontal regeneration potential after tooth root replantation combined with in vitro cultured periodontal ligament cells (PDLCs).Methods:The third and fourth mandibular premolars of two mongrel dogs were extracted and the dog PDLCs were in vitro cultured.The autologous roots combined with PDLCs were replanted into the created cavities in the right mandibular edentulous area one month after premolar extraction.Roots replanted without PDLCs on the left mandible served as the controls. The dogs were sacrificed 2 months after the replantation. Paraffin sections were made and stained with hematoxylin & eosin, then examined histologically.Results:In the samples of root combined with PDLCs implantation, some fiber bundles vertical to the surface of bone were embedded in some inner walls of the alveolar socket opposite to the apical root.Conclusion:Cultured PDLCs in vitro retain the capacity of PDL-like tissue formation even in the artificial alveolar socket.

Objective:To investigate the effect of Shuanghuangbu slow releasing strip (SRSS) on the expression of BMP2 and IGF1 in the experimental regeneration of periodontium. Methods:Periodontal defects were surgically made around the second incisor and the ca nine in four beagle dogs .32 defects were randomly divided into experimental gr oup and control group with 16 defects in each group. SRSS was applied to the e xperimental group and no disposition to periodontal defect in the control group. Two teeth of each dog were randomly chosen as the natural controls.Specimens we re respectively obtained one month and three months after operation. BMP2 and I GF1 were quantitatively analyzed by immunohistochemistry. Results:The positive rate of BMP2 and IGF1 in experimental group were higher t han those in the control( P

Objective To investigate the proliferation and apoptosis in stage-ⅠNSCLC and their prognostic implications.Methods Immunohistochemical technology and TUNEL assay was applied to detect proliferation and apoptosis in 118 lung cancer tissues and 30 normal lung tissues as controls.Results Proliferation Index(PI)was up-regulated in lung cancer tissues compared with that in normal lung tissues and was closely related to T-staging,differentiation and smoking.Apoptotic Index(AI)was up-regulated in lung cancer tissues compared with that in normal lung tissues and was closely related to T-staging.PI was not related to AI in stage-ⅠNSCLC.The patients with high PI had a shorter 5-year survival than those with low PI(33.57% and 73.12%,P=0.0001),and the patients with low AI had a shorter 5-year survival than those with high AI(41.48% and 68.80%,P=0.008).Multivariate analysis showed that PI was a significantly independently predictive factor for patients with stage-ⅠNSCLC(RR=2.473,95%CI:1.278~4.784,P=0.007).Conclusion Stage-ⅠNSCLC is a subgroup with high proliferation and apoptosis.Proliferation plays a more important role in stage-ⅠNSCLC.The assessment of proliferation and apoptosis may provide new insight into prognosis and adjuvant treatment for stage-Ⅰ NSCLC.

The article briefly reviews the aged lung cancer in epidemiology, physical and pathologic traits, and treatments. It includes the matters needing attention of operation with elder lung cancer patients; matters about the radiotherapy; choice of chemotherapeutics or dosage; situation of targeted drug and treatment of Chinese Medicine. Goals of treatment with elder lung cancer patients are prolonging lifetime, improving quality of life. Patients should be treated individually according to their state of illness and constitutions.

Objective To analyze the efficacy of repairing unilateral cleft lip (UCL) with Millard method, and explore the individual operative procedure. Methods According to the difference of lip height between non-cleft and cleft sides, MillardⅠ, MillardⅡ or modified Millard Ⅱ operative approach was chosen to repair UCL, then the clinical effect of operation was evaluated. Results The ideal operative effects were obtained in 208 cases of UCL using various operative approaches based on the individual deformity. There were consistent lip height between both sides, normal vermillion bulk and satisfactory facial appearance after operation. Conclusion The satisfactory efficacy could be obtained by choosing Millard method's operative approaches based on the individual deformity. The modified Millard operative approach could repair all kinds of UCL.

Guangdong province assumes the task of pilot exploration and demonstration for building the preventive health service system of Chinese medicine. In the pilot process of preventive treatment of disease, a health pro-ject of Chinese medicine, sectoral agreements and policy studies are focusing issues. This paper explores the pre-ventive health service system building of Chinese medicine in G uangdong province , from following aspects such as access policy of service agencies, access policy of professional service staff, evaluation mechanism and verify sys-tem, the revision of existing medical subjects of medical institutions, health insurance policies and compensation policies, price policies, proactive technology policies and fiscal policies, incentive policies for the introduction of private capital .

The origin and the course of the thoracic duct and its opening into the vein were studied in 150 cadavers including 15 fetuses and 138 infants. They are classfied into 5 types.1. The normol type of the thoracic duct begins in the abdominal cavity as a single trunk, It ascends along the right side of the aorta and empties into the venous system on the left side at the root of the neck. This type of the duct which is described in the general text book, occurred in 84.67 per cent.2. The two-trunk type of the thoracic duct begins in the abdominal cavity as two trunks and ascends along the each side of the aorta. The two trunks join together at different levels in the thorax forming a single trunk which empties into the venous system on the left side at the root of the neck. This type of the duct occurred in 10.66 per cent.3. The bifurcated-type of the thoracic duct starts in the abdominal cavity as a single trunk and passing cephalad on the right side of the aorta and divides into two branches at the level of the 6th~4th thoracic vertebra, The right branch opens into the venous svstem on the right side and the left branch opens into the venous system on the left side. This type of the duct occurred in 3.33 per cent. The type which ascends along the left side of the aorta was found.4. The right thoracic duct begins in the abdominal cavity as a single trunk and runs its entire course along the left side of the aorta. The termination opens into the right jugular venous angle. This type of the duct occurred in 0.67 per cent.5. The left thoracic duct begins in the abdominal cavity as a single trunk and ascends along the left side of the aorta. It empties into the left jugular venous angle. This type of the duct occurred in 0.67 per cent.

This study is to observe the protection of gross saponins of Tribulus terrestris (GSTT) on cardiocytes impaired by adriamycin (ADR) and approach its mechanism of action. Cardiocytes of neonate rat were cultivated for 72 hours and divided into normal control group, model (ADR 2 mg x L(-1)) group, and GSTT (100, 30, and 10 mg x L(-1)) groups. MTT colorimetric method was deployed to detect cardiocyte survival rate, activities of CK, LDH, AST, SOD, MDA and NO were detected, and apoptosis was detected with flow cytometry. Effect of GSTT on caspase-3 was detected with Western blotting. Compared with control group, contents of CK, LDH, AST, MDA and NO were increased, and activity of SOD was reduced (P < 0.05, P < 0.01, P < 0.001) by ADR. Numbers of survival cells were increased (P < 0.05, P < 0.001), contents of CK, LDH, AST, MDA and NO were decreased, and activity of SOD was increased (P < 0.05, P < 0.01, P < 0.001) by GSTT (100 and 30 mg x L(-1)). Apoptosis of cardiocytes and concentration of caspase-3 can be reduced by GSTT (100 and 30 mg x L(-1)). GSTT can protect cardiocytes impaired by ADR, which are possible involved with its effect of resisting oxygen free radical.
