Objective: Our aim was to analyze the relationship between the concentration of some minerals in saliva and periodontitis.Methods:Twenty-five patients with adult periodontitis (AP group), 25 age and sex matched healthy people(N group) were selected. Unstimulated whole saliva samples were collected and qualified for the concentration of TCa,P,Mg2+, Na+,K+, and Cl-.　Clinical parameters on periodontitis were also assessed for the patients. All the aforementioned indices were measured repeatedly at the end of the fourth week after initial therapy. Results:The clinical condition of the patients improved significantly after treatment. The level of saliva Ca elevated before and after treatment in AP group than that in N group. Before treatment, the concentration of Na+ also increased significantly, but it decreased to normal level after initial therapy. The findings also indicated the positive relationship between the concentration of salivary Na+ and pocket probing depth as well as gingival index before treatment.Conclusion:The elevated level of saliva Ca is a sign of periodontitis and may help the occurrence and progress of periodontitis. The level of saliva Na+ may indicate the pocket depth and degree of gingivitis.The saliva Na＋ is closely associated with the clinical condition of periodontitis.

Objective: To observe the effect of muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting in improving nail fold microcirculation in the patients with shoulder-hand syndrome (SHS) after stroke, and the effects on hemorrheology, calcitonin gene-related peptide (CGRP) and serum substance P (SP). Methods: A total of 72 patients were randomized into an observation group and a control group by the random number table method, with 36 cases in each group. The control group was treated with physical rehabilitation training, and the observation group was treated with additional muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting treatment. The treatment course lasted for 4 weeks. After treatment, the clinical efficacy of the two groups was compared. The changes in shoulder-hand syndrome scale (SHSS), simplified Fugl-Meyer assessment-upper extremity (FMA-UE), visual analog scale (VAS), activities of daily living (ADL), traditional Chinese medicine (TCM) syndrome score, nail fold microcirculation hemorheology indictors [whole blood viscosity (high-shear, low-shear), hematocrit, erythrocyte sedimentation rate (ESR)], CGRP and SP levels were observed. Results: The total effective rate in the observation group was 86.1％, higher than 63.9％ in the control group (P<0.05). The overall curative effect in the observation group was better than that in the control group (P<0.05). After treatment, the scores of pain sensation, edema, external turn and rotation of the arm in SHSS, and the total score were significantly decreased in both groups (all P<0.05), and each score in the observation group was lower than that in the control group (all P<0.05). After treatment, the scores of VAS and TCM syndrome in both groups decreased significantly (all P<0.05), and the scores of FMA-UE and ADL increased significantly (all P<0.05). The scores of VAS and TCM syndrome in the observation group were lower than those in the control group (both P<0.05), and the scores of FMA-UE and ADL were higher than those in the control group (both P<0.05). After treatment, the whole blood viscosity (high-shear and low-shear) and hematocrit in both groups decreased obviously (all P<0.05), and ESR increased obviously (both P<0.05), and the whole blood viscosity (high-shear and low-shear) and hematocrit in the observation group were lower than those in the control group (all P<0.05), and ESR was higher than that in the control group (P<0.05). After treatment, the peritubular state, loop shape, blood flow and total score of nail fold microcirculation in both groups decreased significantly (all P<0.05), and each score in the observation group was lower than that in the control group (all P<0.05). After treatment, SP in both groups decreased obviously (both P<0.05), CGRP increased obviously (both P<0.05), and SP in the observation group was lower than that in the control group (P<0.05), CGRP was higher than that in the control group (P<0.05). Conclusion: Compared with conventional physical rehabilitation training, muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting treatment can significantly reduce the clinical symptoms of SHS, promote the recovery of physical functions, improve the nail fold microcirculation and hemorrheology indictors, and regulate the serum cytokine levels such as CGRP and SP.

BACKGROUND: In clinic, many orthopaedic diseases are related to abnormal increase of intraosseous pressure, such as, avascular necrosis of femoral head and osteoarthritis and so on. Percutaneous bone puncture and other methods can decrease intraosseous pressure and release clinical symptoms immediately. Analysis on the changes in intraosseous pressure and medullary blood rheology following drilling decompression can further recognize the occurrence and development of intraosseous pressure OBJECTIVE: To observe the changes in intraosseous pressure and medullary blood rheology following drilling decompression in rabbits.DESIGN: A randomized and controlled trial.SETTING: Department of Orthopaedics, Affiliated Hospital of Youjing Medical College for Nationalities.MATERIALS: This experiment was carried out at Orthopaedic Department, Affiliated Hospital of Youjing Medical College for Nationalities between March and December 2005. Totally 30 New Zealand purebred white rabbits, of either gender, weighing (2.16±0.35) kg, were provided by Experimental Animals Center of Guangxi Medical University.METHODS: ① Animals grouping and modeling: 30 rabbits were randomly divided into 2 groups: model group and experiment group with 15 in each group. Intraosseous pressure models of the proximal right tibia were created on the rabbits in the two groups and drilling decompression was performed in the proximal tibia of rabbits in the experiment group. ②Measurement of intraosseous pressure of proximal tibia: After rabbits were anesthetized, needle for measuring blood pressure was pricked into the medullary canal at 0.5 cm internal plane up at the tubercle of right tibia.Intraosseous pressure of two groups was measured before and 2 days after decompression with BL-410 biologic functional system. ③ Measurement of medullary blood rheology: Before and 2 days after drilling decompression,medullary blood was extracted and blood rheology was measured with Blood Perfusion Monitor R80 (Vertebral plate type, Version 5.0) in the experiment group.MAIN OUTCOME MEASURES: Value of intraosseous pressure and medullary blood rheology before and after drilling decompression in the proximal right tibia.RESULTS: All the 30 rabbits entered the stage of result analysis. ①Measurement of intraosseous pressure: intraosseous pressure was significantly lower after drilling decompression in the proximal right tibia in the experiment group than in the model group (P ＜ 0.01). It approached normal value of intraosseous pressure of control side [(2.50±0.39) kPa]. Intraosseous pressure in the experiment group was significantly lower after than before drilling decompression (P ＜ 0.01). ② Measurement of medullary blood rheology: Medullary blood viscosity, plasm viscisity, whole blood reduced low-shear viscosity, red cell rigidity index, whole blood high-shear relative viscosity, whole blood low-shear relative viscosity, erythrocyte deformation index and erythrocyte aggregation index at the proximal end of tibia following drilling decompression were significantly lower than those before drilling decompression (P ＜ 0.05 or 0.01). Medullary erythrocyte sediment rate and erythrocyte hematocrit did not change significantly (P ＞ 0.05).CONCLUSION: Drilling decompression in proximal right tibia can obviously decrease intraosseous pressure, dilute medullary blood and decrease blood viscosity.
