BACKGROUND: Compound antitumor coral hydroxyapatite (CCHA) has a good delayed-release and anti-tumor effect. However, whether the high-dose drug contained in the CCHA influences normal induction, conduction and growth of bone tissues at the implant site is unclear.OBJECTIVE: To establish an osteogenesis model of CCHA and to investigate the osteogensis effect and rule of self-made CCHA in vivo. METHODS: Implants of CCHA (20%CDDP-CHA w/w) and CHA(control, 0% CDDP w/w) were implanted into the metaphyseal holes of rabbit femur. X-rays and decalcified histological section of rabbit femoral bone with hematoxylin and eosin staining were used regularly to investigate the degradation of CCHA and CHA, and how bone tissues grow at the implant site. RESULTS AND CONCLUSION: After implantation, CHA crystals were faster than CCHA in connecting with surrounding bone tissues and forming bone bridges. The borderlines of implanted CHA became obscure in 4 weeks. Loose connective tissues were found in pores of the CHA and osteoblasts were growing on the surface. Bone tissues of the surrounding gradually grew into the CHA, finally repaired the bone defects. At the beginning of implantation, CCHA mainly inhibited the growth of surrounding tissues until 6-12 weeks later, normal bone tissues gradually grew into pores of CCHAs, and healed bone defects at 26 weeks. CCHA can inhibit the osteogenesis effects at early stage; however, it can achieve bone healing with surrounding bone defect ultimately.

Objective To study serum IL-22 levels in patients with pulmonary tuberculosis and diabetes mellitus (PPTDM) and to analysis their clinical significance.Methods ELISA was used to detect serum IL-22 levels in 30 cases PPTDM pa-tients,30 cases pulmonary tuberculosis (PTB)patients,30 cases diabetes mellitus (DM)patients and 30 cases healthy vol-unteers (HV).Results Serum IL-22 levels of PPTDM patients (54.4±4.81 pg/ml)were significantly lower than those in diabetes mellitus (DM)patients (72.36±5.12 pg/ml)and healthy volunteers (HV)(68.32±3.08 pg/ml)(t=2.557,P =0.013;t=2.437,P =0.018),respectively.There was no significantly different of serum IL-22 levels between PPTDM and PTB patients (t=1.190,P =0.239).Serum IL-22 levels of diabetes mellitus coincident with pulmonary tuberculosis (DM-PTB)patients (64.62±8.59 pg/ml)were significantly higher than those in pulmonary tuberculosis coincident with diabetes mellitus (PTB-DM)patients (44.21±2.68 pg/ml)(t=2.267,P =0.031).Conclusion IL-22 may play an important role in PPTDM development.

Objective To explore factors influencing the prognosis of hepatocellular carcinoma (HCC) patients after hepatectomy. Methods From May 1994 to January 1998, 189 patients who underwent hepatectomy for HCC were enrolled for reviewing their clinical characteristics, treatment and prognosis. Twenty-two parameters contributing to long-term survival rate (SR) and disease-free SR were analysed. Results The 3,5-year cumulative SR of the whole group was 63%,45%, respectively. The 3,5-year SR and disease-free SR in the curative resection (CR) group ( n =162) were 67%,47% and 45%,26% respectively. Results showed that the way by which a tumor was found, tumor size, portal tumor thrombi, satellite nodule, TNM stage, cirrhosis type, recurrent and treatment, blood transfusion, differentiation grade,and CR were risk factors by individual variable analysis( P =0.0000～0.0034); A multivariable analysis showed that CR, tumor size, tumor finding mode and reoperation were significant factors associating with prognosis( P =0.0000～0.0024). Blood transfusion and type of cirrhosis were closely correlated with tumor-free survival ( P =0.0001). Conclusions Curative resection, tumor size, reoperation for recurrence were important factors for recurrence by multivariate analysis. The severity of concomittant liver cirrhosis and perioperative blood transfusion were closely correlated with postoperative tumor free survival.

Objective: To explore the mechanism of traditional Chinese medicine(TCM) combined with regular therapy in the treatment of pneumonia with systemic inflammatory response syndrome(SIRS) in(children).Methods: Sixty-four children with pneumonia including 51 cases with SIRS complication were(randomly) divided into three groups: treatment group(regular therapy+TCM,n=26),control group Ⅰ((regular)(therapy) only,n=25) and the control groups Ⅱ(13 pneumonia children without SIRS(receiving)(routine) treatment). The dynamic changes of tumor necrosis factor-?(TNF-?),interleukin-6(IL-6) and IL-8 were measured before and after treatment in all children.Serum Creactive protein(CRP) and total white blood cell(WBC) count were measured simultaneously.Clinical symptom and sign scores were(performed)(5 days) after treatment in children with pneumonia and SIRS complication.Results: Before(treatment),serum TNF-?,IL-6,IL-8 and CRP concentrations were significantly higher in treatment group and(control) group Ⅰ than(control) group Ⅱ(all P

Objective To assess the therapeutic effect of combination chemotherapy of gemcitabine and cisplatin by double way plus implantation of radioactive seed 125I implantation in treating stage Ⅲ non-small cell lung cancer. Methods Sixty cases with stage Ⅲ non-small cell lung cancer were randomly divided into two groups with random number table. In group A (in interventional treatment group, n = 30),the gemcitabine 1000 mg/m2 and one third of the cisplatin 100 mg/m2 was given using seldinger technique for transcatheter bronchial arterial infusion chemotherapy on day 1. Two-thirds of the cisplatin 100 mg/m2 was infused in veins on day 2 and 3. The gemcitabine 1000 mg/m2 was infused in veins on day 8, 21 days for a period. In group B (interventional - 125I groups), the method of combination chemotherapy of gemcitabine and cisplatin was the same as in Group A. After ten days of arterial perfusion, 125I seeds were implantated, 21 days for a period. All patients received at least 2 cycles. The imaging evaluation of patients after treatment standards included complete remission (CR), partial remission (PR), stable (SD),progressive disease (PD), effective rate (CR + PR)/30 and clinical benefit rate (CR + PR + SD)/30.Non-parametric rank sum test was used to compare short-term effect of the two groups treatment of two cycles.x2 test was used to compare year survival, Kaplan-Meier method was used to calculate median survival,log-rank test method was used to difference between the groups. Results In group A, there were 17 PR,9SD and 4 PD. The overall response rate was 56. 7% (17/30) and clinical beneficial rate was 86. 7% (26/30). In Group B, there were 2 CR, 21 PR, 7 SD. The overall response rate was 76.7% (23/30) and clinical beneficial rate was 100% (30/30). There was significant difference between the two groups (P =0. 036). In group A, the 1 year survival rate was 46. 7% (14/30) and the 2 year survival rate was 36. 7%(11/30), median survival time (MST) was 10 months . In group B, the 1 year survival rate was 76. 7%(23/30) and the 2 year survival rate was 63. 3% (19/30) , median survival time (MST) was 27 months.There was a significant difference between two group in 1 year survival rate (P = 0. 017), 2 year survival rate (P = 0. 039) and median survival time (P = 0. 006). Conclusion The treatment effects of Ⅲ stage non-small cell lung cancer by gemcitabine and cisplatin combination chemotherapy with double way plus radioactive seed 125I implantation was better than gemcitabine and cisplatin combination chemotherapy with double way.

Objective To assess the therapeutic outcomes of transcatheter arterial chemoembolization combined with percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis for primary hepatic carcinoma accompanied by portal vein tumor thrombus. Methods Thirty patients with primary hepatic carcinoma accompanied by portal vein tumor thrombosis of type Ⅱ and type Ⅲ were randomly divided into two groups. The Child-Pugh ratings (class A and B) of group A and B were 9 vs 9 (class A) and 5 vs 7 (class B) respectively (χ~2 = 0.201, P > 0.05). The constitution of Type Ⅱ and type Ⅲ portal vein tumor thrombus in group A and B were 8 vs 9 and 6 vs 7 respectively (χ~2 =0.002, P>0.05). The median values of ALT, TBIL, ALB and AFP in group A and B were 58.7U/L vs 70.5 U/L (W=191.5, P>0.05), 21.4 μmol/L vs 21.7μmol/L (W=203, P>0.05), 35.3 g/L vs 37.5 g/L (W = 214, P > 0.05) and 680 μg/L vs 873 μg/L (W = 179. 00, P > 0.05) respectively. Group A was treated with transcatheter arterial chemoembolization (TACE) using emulsion made up of adriamycin, cisplatin, mitomycin and ultraliquidlipiodol plus percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis using emulsion consisted of cisplatin and ultraliquidlipiadol, while group B was treated with TACE only as a control group. Survival analyses were performed via the Kaplan-Meier test in SPSS11.5 with the log-rank tests with an threshold of 0.05. Results The 3, 6 and 12 months survival cases of group A and B were 11 vs 10, 10 vs 3, and 7 vs 0 respectively. The median survival time of group A and group B were 14.0 months and 4.0 months respectively. The difference of the two groups was significantly (χ~2 =11.728, P<0.01). There was no severe side-effect related to therapy in both groups. Conclusion Comparing with the control group, TACE combined with percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis could significantly prolong the median survival time of patient with primary hepatic carcinoma accompanied by type Ⅱ and type Ⅲ portal vein tumor thrombosis.

[ABSTRACT]OBJECTIVETo improve the understanding and treatment of otogenic deep neck abscess.METHODSTo analyse the treatments of 2 cases retrospectively and do the literature review.RESULTS 2 cases had long history of otitis media, showed abnormal signal connection on MRI image between neck lesion and middle ear. They were cured by mastoidectomy and drainage from neck abscess to mastoid cavity.CONCLUSIONThe otogenic deep neck abscess is different from other one in the etiology, pathogenesis, pathogenic bacteria, treatment and so on. The neck MRI examination has obvious advantages in the nature of the lesion, the resolution of the soft tissue and the correlation of lesions between the neck and the mastoid, and can be used as the predominant treatment. Incision and drainage of the neck abscess is unnecessary if operated on time. Before the neck abscess is cured thoroughly, keeping drainage of the mastoid tip is very important for prevention of recurrence. Postoperative change dressing should also be strengthened.

OBJECTIVE: To analyze the characteristics of vestibular migraine (VM), in order to understand the auditory and vestibular function. METHOD: One hundred cases of confirmed or suspected VM patients were observed. Routine examination including pure tone test, vestibular dual temperature test and vestibular evoked myogenic potential(VEMP) and video head impulse test(v-HIT) Were conducted. RESULT: The incidence of male and female was about 1.00 : 2. 57. The average age of onset was 47 years, of which the youngest was 19 years old, and the oldest was 74 years old. Ninty-three cases of patients presented with vestibular sensitive performance, including photophobia, phonophobia,or motion sensitive. Fourty-two patients had migraine at the onset of the disease. Thirty-four patients had cochiear symptoms, including tinnitus, ear fullness, or epicophosis. In seventeen cases of fatigue, tension or poor sleep can cause vertigo. Nine patients had low blood pressure, 7 patients presented with hypertension. Two cases of vertigo were closely related to the change of position, and 1 case had visual aura. In the experiment, 94 patients had undergone VEMP test,with 44 cases of abnormal VEMP value. Seventy-nine patients had been examined v-HIT,of whom 2 patients were abnormal (both of which were reduced). Pure tone audiometry was abnormal in 35 cases. Five cases of patients showed abnormal vestibular-double temperature test. CONCLUSION Vestibular migraine is more prone to female, with young middle age, and can be accompanied by cochlear symptoms. Vestibular function tests (low frequency and high frequency) are normal.
