Objective To analyze the clinical and immunological features of 45 pediatric patients with lupus nephritis (LN). Methods Forty-five LN patients were included in this study. Clinical, pathological data and immunological parameters were retrospectively analyzed. Results Forty-five LN patients had 6 males and 39 females, with the mean onset age of (10.9 ± 2.8) years. Acute nephritis was the most common type, accounting for 42.2%. Nephrotic syndrome accounted for 31.1%. Renal biopsy showed class II (17.8%), III (4.4%), IV (48.9%), V (2.2%), V+III (6.7%)and V+IV (13.3%)in 42 cases. The remis-sion rate reached 91.1%in the early therapeutic stage, and 15.0%patients recurred after 24-month follow-up. Conclusions The clinical manifestations of LN children are diverse. The renal pathology is complex. The clinical manifestations in part of the chil-dren are not consistent with renal pathology.

Objective To investigate any effects of rubbing acupoints on the right leg on activation and deactivation responses in the human cerebellum. Methods Ten male, healthy, right-handed subjects were examined using functional magnetic resonance imaging (fMRI) while their Zusanli (ST36) , Yanglingquan (GB34),Fenglong (ST40) and Sanyinjiao (SP6) acupoints on the right lower extremity were stimulated. A block-designed method was applied. A piece of sponge was used to rub all the above-mentioned acupoints for stimulation. The mean values of the activation and deactivation signals in different cerebellar zones induced by stimulating each acupoint were calculated.Results Each acupoint could modulate cerebellum function in its specific way, but all acupoints induced the largest mean values in the Vermis Crus I area. The largest deactivation effects for all acupoints except Sanyinjiao were located in the Vermis VI area. For each acupoint, left and right side activation effects of the 20 zones of the cerebellum were basically consistent, though the mean values of most zones were higher on the right side. Conclusions The four acupoints studied not only shared common modulating effects, but also showed point-specific influence on cerebellum function. The effects exerted by each acupoint on the Vermis were greater than that on the cerebellar hemispheres. The phenomena observed in this study could contribute to acupoint selection during rehabilitation.

OBJECTIVESTo investigate the relationships among rotational alignment reference axes of distal femur and tibial mechanical axis, and determine the safest rotational alignment reference axis.
METHODSDigital photos were taken of 30 cadaveric lower extremities with knee in extension and flexion at 90 degrees , angles were measured among tibial mechanical axis and a line perpendicular to clinical epicondylar axis, a line perpendicular to surgical epicondylar axis, Whiteside's line and femoral mechanical axis. Statistical analysis of relationships among those axes were performed.
RESULTSThe angles among the tibial mechanical axis and a line perpendicular to the clinical epicondylar axis, a line perpendicular to the surgical epicondylar axis, Whiteside's line and femoral mechanical axis were 0.6 degrees varus, 3.9 degrees varus, 0.2 degrees valgus and 3.0 degrees varus respectively. The angle between the femoral mechanical axis and the tibial mechanical axis was significantly larger than the angles among the tibial mechanical axis and a line perpendicular to the clinical epicondylar axis, the Whiteside's line (P < 0.05). There was no significant difference compared with the angle between a line perpendicular to the surgical epicondylar axis and the tibial mechanical axis. Angles of the clinical epicondylar axis, the surgical epicondylar axis and the Whiteside's line between knee extension and flexion were 2.3 degrees valgus, 0.9 degrees varus and 3.1 degrees valgus respectively.
CONCLUSIONThe surgical epicondylar axis rather than the clinical epicondylar axis or the Whiteside's line is the safest femoral rotational alignment reference axis intraoperatively.

This study was aimed to investigate the reversible effect of tetrandrine, toremifene and their combination on multidrug resistance of K562/A02 cell line. The IC(50) (the concentration causing 50% inhibition of cell growth) of adriamycin (ADR) were assayed by MTT method, the expression of MDR1 mRNA was measured by RT-PCR, the concentration of p-glycoprotein (P-gp) and intracellular ADR were detected by flow cytometry. The results showed that the IC(50) of ADR on K562/A02 and K562 cells were 57.43 and 1.16 mg/L, respectively. The IC(50) of ADR on K562/A02 cells after treatment with tetrandrine, toremifene and both combination were 14.12, 20.74 and 9.14 mg/L respectively, but both drugs did not influence the IC(50) of ADR on K562 cells. Pretreating K562/A02 cells with toremifene (2.5 micromol/L), tetrandrine (1 micromol/L) or both for 72 hours partially restored the sensitivity of K562/A02 cells to ADR. Tetrandrine and toremifene (alone or combination) elevated the ADR concentration in K562/A02, down regulated the expressions of P-gp and MDR1 mRNA. It is concluded that multidrug resistance of K562/A02 cells can be partially reversed by tetrandrine or toremifene, the combination of both drugs shows a higher synergistic reversal effect.

OBJECTIVETo explore therapeutic effects of bone setting manipulation for the treatment of over degree II supination-eversion fractures of ankle,and analyze manipulative reduction mechanism.
METHODSFrom 2005 to 2008, 95 patients with over degree II supination-eversion fractures of ankle were treated respectively by manipulation and operation. There were 43 cases [11 males and 32 females with an average age of (44.95 +/- 12.65) years] in manipulation group, and 2 cases were degree II, 11 cases were degree III, and 30 cases were degree IV. There were 52 cases [21 males and 31 females with an average age of (39.96 +/- 13.28) years] in operative group,and 6 cases were degree II, 18 cases were degree III, and 28 cases were degree IV. Bone setting manipulation and hard splint external fixation were applied to manipulative group. Operative reduction internal fixation was performed in operative group. X-ray was used to evaluate reduction of fracture before and after treatment, 2 months after treatment. Ankle joint function was evaluated according to Olerud-Molander scoring system after 6 months treatment.
RESULTSAll patients were followed up with good reduction. Three cases occurred wound complication in operative group, but not in manipulative group. In manipulation group, 19 cases got excellent results, 20 cases good and 4 cases fair; while in operative group, 30 cases got excellent results, 20 cases good and 2 cases poor. There were no significant differences in fracture reduction and ankle joint function recovery between two groups (P > 0.05). Efficacy of operative treatment was better than that of manipulative treatment at degree IV fracture (P < 0.05).
CONCLUSIONBone setting manipulation is a good method for treating supination-eversion ankle joint fractures, which has advantages of simple and safe operation, reliable efficacy. For ankle join fracture at degree IV, manipulative reduction should be adopted earlier, and operative treatment also necessary

OBJECTIVETo study the relationship between hRad17 mRNA expression and clinicopathologic factors and lymph node metastasis of gastric cancer, and to assess the significance of predicting the extent of lymph node metastasis and prognosis.
METHODShRad17 mRNA expression was examined in matched primary lesions, normal gastric mucosa and lymph node metastatic lesions among 52 gastric cancer patients by reverse transcription polymerase chain reaction (RT-PCR), polyacrylamide gel electrophoresis (PAGE) and silver stain with the relation between hRad17 mRNA expression and clinicopathologic factors analyzed. At the same time, hRad17 mRNA expressions in 5 gastric benign lesions and SGC7901 gastric carcinoma cell lines were also examined.
RESULTSThe primary tumor samples (88.4% positive) showed a significantly higher level of hRad17 expression compared with matched normal tissue (76.9% positive) (P = 0.014), so did the lymph node metastatic samples (94.2% positive) (P = 0.001). The hRad17 mRNA expression showed a low level in benign lesions, but very high in SGC7901 cell line. The hRad17 mRNA expression showed a higher level in patients with the number of lymph node metastasis above 15 than below 15 (P = 0.02), so did the diffused growth than the mass-like growth (P = 0.04).
CONCLUSIONThe method of PAGE and silver stain can improve the sensitivity of RT-PCR. The degree of lymph node metastasis and invasiveness of carcinoma cells are more serious in cases with hRad17 mRNA overexpression, and extensive lymph node dissection should be carried out for these patients. Examination of hRad17 expression by RT-PCR before surgery is indicated to arrive at an optimum treatment scheme and to estimate the prognosis.
