Supernumerary tooth is a rare case. This report described a case of nasal cavity supernumerary tooth association with maxillary sinusitis. A 28-year-old male patient reported with the chief complaint of nasal obstruction, headache and purulent secretion for the past three months. Clinic examination and CT examination showed that there was a supernumerary tooth in the right nasal bottom, and maxillary sinus was infected in the same side. This patient was performed supernumerary tooth removing and given antibiotics for 3 days. Ten days after the operation, there was no clinical symptoms, and nasal bottom mucosa was normal. After 3 months of follow-up, reexamination of coronal CT scan appeared normal.

Objective To understand the combined effects of selenium (Se), germanium (Ge) on the level of Ca, Mg, Zn in the tissues of rats exposed to fluoride(F). Methods SD rats were divided into 5 groups and respectively treated with distilled water(control), 100 mg NaF/L(through drinking water), based on the fluoride treatment, Se, Ge were respectively given by gavage at the doses of 0.1 mg Na2SeO3/(kg?d), 10 mg Ge-132/(kg?d) and 0.1 mg Na2SeO3/(kg?d) plus 10 mg Ge-132/(kg?d) for 90 days. The body weight, activity, and general state were observed. The content of Ca,Mg,Zn in the serum,liver and kidneys were determined by flame atomization method. The content of F was detected by ion chromatography. Results The body weight in F+Se, F+Ge and F+Se+Ge groups were higher than that in F group and lower than that in the control group. The content of F in the liver, kidney in F+Se, F+Ge groups were higher than that in F+Se+Ge group(P

Objective To study the antagonistic effects of selenium and germanium (Se-Ge) in combination on the kidney damage induced by fluoride in rats.Methods Fifty SD rats were randomly divided into 5 groups,the control group (distilled water),fluoride group (NaF,100 mg/L),fluoride plus selenium group (100 mg/L NaF + 20 mg/L Na2SeO3),fluoride plus germanium group(100 mg/L NaF + 2 000 mg/L Ge-132) and fluoride plus selenium and germanium group(100 mg/L NaF+ 20 mg/L Na2SeO3+ 2 000 mg/L Ge-132),10 in each group (males and females were in the same number).The administration was conducted through gavage for 90 days.After 90 days of treatment,the kidneys were collected and the organ coefficients were calculated,MDA contents,SOD and GSH-Px activities in the tissue were determined and the histopathological examination was done.Results Fluoride decreased the organ coefficient of kidney,Se and/or Ge showed an obvious antagonism to fluoride,administration in combination was more efficient than singly.Na2SeO3 and/or Ge-132 had an antagonistic effect to fluoride in the increase of lipid peroxide(MDA) and decrease of the activity of glutathione peroxidase(GSH-Px),superoxide dismutase(SOD).Na2SeO3 and/or Ge132 could prevent the pathologic damage caused by fluoride in the kidneys.Conclusion Na2SeO3 and Ge-132 in combination has an obvious antagonistic effect on fluoride-induced kidney damage.

Meridian syndromes are the required basic knowledge for mastering Science of Meridians, Collaterals and Acupoints but have not brought the adequate attention on the teaching program. The writers discovered' that the content of this section occupied a decisive role for developing the students' clinical thinking ability and, stimulating their interests to learn classical TCM theories. It's necessary to enhance the importance on meridian syndromes during teaching program. The teaching program was discussed in three aspects, named workshop pattern, competitive pattern and multimedia pattern. This teaching method may improve students' interests in the study on classical TCM theories, deepen the understanding on knowledge and motivate students' learning autonomy so that the teaching quality can be improved.

Objective To review the experience of perioperative management and effect of coronary artery bypass grafting (CABG) for patients of aged＞80 years.Methods We studied 118 cases with CABG for patients of age＞80 years from January 2002 to December 2012.The other 1034 cases with CABG for patients aged 60-80 years were enrolled as control group.Logistic regression analysis was used to assess the effect of age on operative mortality and morbidity.Results The recent mortality was higher in group aged＞80 years [6.8％(8 cases) vs.3.1％(32 cases)].Through multivariate logistic regression,the patients aged＞80 years versus control were concerned about some postoperative adverse events as follows:higher mortality (OR =3.45,95 ％ CI:2.86-4.23),dialysis (OR=3.56,95％CI:3.01-4.32) and re-intubation(OR=3.87,95％CI:3.45-4.87),delayed healing of incision(OR=4.05,95 ％ CI:3.47 5.74),prolonged mechanical ventilation(OR=3.76,95 ％ CI:3.435.01),prolonged ICU stay (OR =2.98,95 ％ CI:2.67 4.12),prolonged hospital stay (OR =2.87,95％CI:2.36-3.96).Conclusions Age＞80 years is an important factor of postoperative mortality and morbidity for CABG.We need pay more attention to perioperative management.

Objective To explore the expression of glucose-regulated protein (Grp) 78 in ovarian cancer tissues and its clinical significance.Methods The expression of Grp78 in 60 cases of ovarian cancer tissue,15 cases of ovarian borderline tumor tissue,10 cases of normal ovarian tissue,10 cases of ovarian cyst tissue,was detected by immunohistochemistry,and analyzed the relationship between its expression and clinicopathological features of ovarian cancer.Results The expression of Grp78 in ovarian borderline tumor and ovarian cancer tissue was significantly higher than that in normal ovarian and ovarian cyst tissue[7/15 and 68.3％ (41/60) vs.1/10 and 1/10] (P ＜0.05).The expression of Grp78 was positively correlated with clinicopathological staging and lymphatic metastasis of ovarian cancer (P ＜ 0.05),negatively correlated with histological differentiation (P ＜ 0.05).No correlation with age and ascites (P ＞ 0.05).Conclusions The levels of Grp78 are elevated in ovarian cancer specimens; high expression of Grp78 maybe participate in the occurrence,development,and prognosis of ovarian cancer.Increased expression of Grp78 might be a useful marker for predicting the carcinogenesis and progression of ovarian cancer.

Objective To observe the therapeutic effect of arthroscopic debridement combined with oral use of Chinese medicine Guanjietong Tablets ( GT) for knee osteoarthritis in the early and middle stage. Methods Ninety knee osteoarthritis patients in the early and middle stage were evenly randomized into three groups, namely GT group, glucosamine sulfate group and blank control group. All of the three groups received arthroscopic debridement, and additionally, GT group and glucosamine sulfate group were given the corresponding medicine orally. We observed Lysholm knee scores of the three groups before operation, and 2 weeks, 3 months and one year after operation, and compared the knee joint space before operation and one year after operation showed by digital X-ray photograpy. Results ( 1) Lysholm knee scores in the three groups were increased 2 weeks, 3 months and one year after operation when compared with those before operation, the difference being significant (P<0.05) . Three months and one year after operation, the scores of GT group and glucosamine sulfate group differed from those of the blank control group (P<0.01). One year after operation, the scores of GT group differed from those of glucosamine sulfate group ( P<0.05). ( 2) The results of knee joint space showed by digital X-ray photography at knee position of weight loading indicated that the difference was insignificant between GT group and glucosamine sulfate group one year after operation ( P> 0.05) , but the difference between the two groups and the blank control group was significant (P<0.05). The difference of knee joint space was insignificant before operation and one year after operation in GT group and glucosamine sulfate group ( P>0.05) , while was significant in the blank control group ( P<0.05). Conclusion Arthroscopic debridement alone has certain short-term curative effect in treating knee osteoarthritis in the early and middle stage, but the effect will decline with the extension of time. Arthroscopic debridement combined with Guanjietong Tablets could delay the narrowing of joint space and maintain the clinical curative effect, which will delay the time for artificial joint replacement.

Objective To study the anti-inflammatory and analgesic effects of Baihuadan Analgesic Spray, so as to provide theoretical basis for further development of new drugs. Methods Prostaglandin E2 (PGE2) in the inflammatory tissues of mice with xylene-induced auricular inflammation and in the rats with albumen-induced pedal swelling were measured for the observation of anti-inflammation action of Baihuadan Analgesic Spray. The pain threshold in mouse hot-plate test and mouse acetic acid writhing test was determined to observe the analgesic effect of Baihuadan Analgesic Spray. Results Middle dose of Baihuadan Analgesic Spray (1 mg/mL) significantly reduced the auricular swelling rate induced by xylene in mice, improved the pain threshold of mice and prolonged pain latency in hot plate test (P < 0.05 or P < 0.01). High dose of Baihuadan Analgesic Spray (2 mg/mL) reduced the content of PGE2 in pedal inflammatory tissues (P < 0.05), and the effect on reducing the times of mouse writhing was obviously superior to that of the Voltaren Gel group. Conclusion Baihuadan Analgesic Spray has obvious anti-inflammatory and analgesic effects.

Objective To investigate the clinical significance.of thrombocytopenia in systemic lupus erythematosus (SLE).Methods One hundred and two SLE patients with thrombocytopenia who were admitted to Peking University People's Hospital were involved in the study.SLE patients without thrombocytopenia were controls.Clinical and laboratory characteristics were analyzed.T-test and Chi-square test were used for inter-group comparison.Results Patients with thrombocytopenia had more organ damage than those without,although the disease activities (SLEDAI) were not different between these two groups.Bone marrow characteristics were analyzed and 16 patients were amegakaryocytic.However,there were no differences observed between patients with amegakaryocytosis and normal megakaryocytes in organ damage,disease activity and response to therapy.Conclusion Lupus patients with thrombocytopenia usually have more organ damage.About 32％ of those patients are amegakaryocytosis.
