BACKGROUND: Fibular fixation and tantalum rod implantation are two commonly used methods for the treatment of early osteonecrosis of the femoral head (ONFH), both of which can effectively delay or even reverse the progress of ONFH. However, further comparative evaluation on their mechanical properties and therapeutic efficacy is required.OBJECTIVE: To compare the clinical efficacy of fibular fixation and tantalum rod implantation on ONFH at early stage.METHODS: Fifty-eight patients (81 hips) suffered from ONFH with ARCO stage 1 and stage 2, and underwent fibular fixation (30 cases, 41 hips) or tantalum rod implantation (28 cases, 40 hips). Postoperatively, both groups were followed up for over 2 years. The Harris scores of the hip were compared between two groups before and after treatment. With femoral head collapse and the collapse distance > 4 mm as observation points, the survival rate of the femoral head was compared between two groups.RESULTS AND CONCLUSION: The postoperative Harris scores of the two groups were significantly improved than before (P < 0.05). With the appearance of femoral head collapse as the observation point, the Kaplan-Meier survival curve showed that the overall survival rate of the hip was 83% in the fibular fixation group and 65% in the tantalum rod implantation group. After examined by log-rank (Mantel-Cox), there was a significant difference in the survival rate of the hip at Stage IIC between two groups (P=0.0431). With > 4 mm collapse as the observation point, the Kaplan-Meier survival curve showed that overall survival rate of the hip was 95% in the fibular fixation group and 83% in the tantalum rod implantation group. After examined by log-rank (Mantel-Cox), there was a significant difference in the survival rate of the hip at Stage IIC between two groups (P=0.0418). To conclude, both fibular fixation and tantalum rods implantation applied to ONFH at early stage can effectively improve the hip function, and the survival rate of the hip at ARCO Stage IIC is better in patients undergoing fibular fixation than tantalum rod implantation.

OBJECTIVETo investigate association of vitamin D receptor (VDR) gene polymorphisms with the susceptibility to chronic periodontitis (CP) of Han Nationality.

METHODSBuccal swabs from 166 patients with severe, moderate and mild CP respectively and 80 matched control individuals were collected. DNA was extracted from these buccal swabs using Chelex-100 method. VDR BsmI, ApaI, TaqI were tested with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The distribution of the genotypes and allele frequencies in the patient and control groups were analyzed.

RESULTSThe frequency of VDR ApaI allele A was significantly higher among patients with CP than controls. Frequencies of VDR ApaI allele A were significantly higher in severe CP patients than in moderate CP and mild CP respectively. There was no significant difference in the genotype distribution or the allele frequencies of VDR BsmI and TaqI between the controls and CP patients.

CONCLUSIONSThese data indicate that VDR ApaI allele A may be related to the susceptibility to CP in Han Nationality.

BACKGROUNDFrom late May 2009, sporadic imported cases of novel influenza A (H1N1) were continuously confirmed in Shanghai, but there were few reports on its clinical presentation in China. The aim of the study was to investigate the demographic and clinical features of the laboratory-confirmed cases and the treatment with oseltamivir.

METHODWe performed a retrospective study in the Shanghai Public Health Clinical Center (SHAPHC), reviewing the medical records of the laboratory-confirmed patients derived from June 10 to July 20, 2009.

RESULTSA total of 156 cases were enrolled, of whom 152 had a history of recent travel. The mean age was 22.6 years and 89 cases (57.1%) were males. The most common symptoms were fever, cough, and sore throat, with children more likely to run a temperature above 38.5 degrees C than adults. The mean leucocyte count was 5.4 x 10(9)/L, the mean neutrophil count 3.2 x 10(9)/L and the mean lymphocyte count 1.4 x 10(9)/L. Other findings included a normal range or elevated level of C-reactive protein (CRP) and glutamic-pyruvic transaminase and a normal or decreased level of prealbumin; the levels of prealbumin and CRP were significantly lower in the children than in the adults. Fifty-two patients had abnormal chest CT results, with small unilateral or bilateral pulmonary infiltrates, axillary and mediastinal lymphadenopathy and local pleural thickening, while no cases showed symptoms of hypoxia. All the patients received oseltamivir and recovered without complications, but the duration of fever and virus shedding were significantly longer in the children than in the adults.

CONCLUSIONSTravel-related circulation may be an important reason for the H1N1 epidemic in the non-epidemic areas, and the virus caused mild respiratory symptoms. The infection in children was more severe in terms of prealbumin levels, temperature, the duration of fever and virus shedding. Oseltamivir was effective for H1N1, but more effective in the adults than in the children.

OBJECTIVETo explore the diagnostic value of the dual-energy technique with dual-source computed tomography (DSCT) for anterior cruciate ligament injuries.

METHODSThe clinical data of 8 patients with arthroscopic results were retrospectively reviewed. All patients underwent two- and three-dimensional imaging by multiplanar reconstruction, volume rendering, and tendon mode on DSCT. Dual-energy characteristics were compared with arthroscopic results.

RESULTSSix patients who were arthroscopically diagnosed as anterior cruciate ligament injuries, all of them were also correctly diagnosed by DSCT. Two patients who were arthroscopically diagnosed as normal, one was also diagnosed as normal by DSCT and the other was misdiagnosed. The overall agreement rate was 87.5% (7/8) . Under the dual energy tendon mode, the dual energy staining of the injured anterior cruciate ligament was lower than that of the contralateral normal cruciate ligament of the patient.

CONCLUSIONThe staining diminution in DSCT imaging may be a new feature that can be used to effectively diagnose anterior cruciate ligament injury.

Objective To study the pharmacokineties and bioequiva-lenee of two demostic cefprozil tablets.Methods Twenty healthy volun-teers were randomized into two groups,whose plasma concentrations of cis and trans isomers of eefprozil were determined at different time after single oral dose of 1 g cefprozil tablets by own control by HPLC method.The pharmacokinetic pammeters were computed and which were experi-enced variance analysis.Results Gis cefprozil:the main pharmaeoki-netic parameters of refe:rence and trial cefprozil tablets were as follows:t_(max) were(2.4±1.0),(2.3±0.8)h;C_(max) were(15.4±3.5),(14.8±2.8)μg·mL~(-1);t_(1/2) were(1.4±0.1),(1.4±0.1)h;MRT were (3.4±0.6),(3.4±0.6)h;AUC_(0-t) were(61.2±10.6),(60.3±11.4)μg·h·mL~(-1);AUC_(0-∞) were(64.7±11.2),(64.5±11.7)μg·h·mL~(-1),respectively.Trans cefprozil:the relative bioavailability of the trial preparation was(99.3±14.5)%.Trans cefprozil:the main pharmacokinetic parameters of reference and trial cefprozil tablets were as follows:t_(max) were(2.4±0.9),(2.4±0.9)h;C_(max) were(1.6±0.3),(1.5±0.3)μg·mL~(-1);t_(1/2) were(1.2±0.2),(1.5±0.6)h;MRT were(3.2±0.7),(3.2±0.7)h;AUC_(0-t) were(6.1±1.4),(5.6±1.3)μg·h·mL~(-1);AUC_(0-∞) were(6.1±1.4),(5.6±1.3)μg·h·mL~(-1),respectively.The relative bioavailability of the trial preparation was(94.0±17.5)%.Conclusion The results shows that the trial preparation and the reference prepara-tion of cefprozil were bioequivalent.

OBJECTIVETo investigate the significance of flexible bronchoscopy in children with respiratory diseases.

METHODSA retrospective analysis was performed for the clinical data of 80 children who were hospitalized due to respiratory diseases (including severe pneumonia, Mycoplasma pneumoniae pneumonia with atelectasis/lung consolidation/local emphysema, protracted pneumonia, coughing and wheezing of unknown cause, chronic cough of unknown cause, and laryngeal stridor) and who underwent flexible bronchoscopy/alveolar lavage.

RESULTSBronchoscopy found that all the 80 children had endobronchial inflammation, among whom 28 children had severe airway obstruction by secretion. Twenty-four children had congenital airway dysplasia besides endobronchial inflammation, and three children had bronchial foreign bodies. In the children with coughing and wheezing of unknown cause and laryngeal stridor, some had congenital airway dysplasia or bronchial foreign bodies. Among the 27 children with Mycoplasma pneumoniae pneumonia, 26 had severe airway obstruction/embolization by secretion; 25 children (93%) underwent chest imaging again at 2 weeks after alveolar lavage, and the results showed complete or partial lung recruitment. Among the 80 children who underwent bronchoscopy, 3 had severe hypoxemia during surgery, 1 had epistaxis, 1 had minor bleeding during alveolar lavage, 3 had transient bronchospasm, and 5 had postoperative fever; these children were all improved after symptomatic treatment.

CONCLUSIONSFlexible bronchoscopy is safe and reliable in children with respiratory diseases. Early alveolar lavage under a flexible bronchoscope is recommended for children with severe/refractory Mycoplasma pneumoniae pneumonia to improve prognosis. Flexible bronchoscopy is recommended for children with recurrent coughing and wheezing and persistent laryngeal stridor, in order to directly observe the throat and airway under an endoscope.

OBJECTIVETo explore the possible mechanism of the inhibitory effect of liver X receptor alpha (LXRalpha) on lipopolysaccharide (LPS)-induced inflammation in mouse Kupffer cells (KCs).

METHODSThe KCs isolated from the liver of male KM mice and cultured in RPMI 1640 containing 20% FBS for 24 h were divided into control, LPS, T0901317, and LPS+T0901317 groups with corresponding treatments. The expressions of LXRalpha, interferon regulatory factor 3 (IRF3) and glucocorticoid receptor interacting protein 1 (GRIP1) in the KCs were detected by Western blotting. The levels of interferon beta (IFNbeta), tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) in the supernatant were detected by enzyme-linked immunosorbent assay (ELISA).

RESULTSThe level of LXRalpha protein was highest in T0901317 group and lowest in LPS group, and was significantly higher in LPS+T0901317 group than in LPS group but lower than in T0901317 group (P<0.05). The levels of IRF3 and GRIP1 protein were the highest in LPS group, and significantly lowered by T0901317 treatment (P<0.05). The expression of IRF3 and GRIP1 proteins in LPS group and LPS+ T0901317 group were significantly higher than those in the control and T0901317 groups (P<0.05). The concentration of IFN-beta was significantly higher in LPS group than in the control and T0901317 group (P<0.05), and decreased in LPS+T0901317 group in comparison with that in LPS group (P<0.05). IFN-beta was the lowest in T0901317 group. The levels of TNF-alpha and IL-1beta were the highest in LPS group (P<0.05), and comparable between the other 3 groups (P>0.05).

CONCLUSIONPre-treatment with T0901317 before LPS stimulation can suppress the expressions of IRF3 and GRIP1 to inhibit the inflammation and hence Kupffer cell activation.
