Objective To observe the therapeutic effect of acupuncture therapy for the rat model of type 2 diabetes mellitus (T2DM) combined with renal hypertension and try to explore its mechanism. Methods We randomly select 10 Wistar rats as the blank group and 40 rats were used to make the model groups, which were divided into simple diabetes group, simple renal hypertension group, the compound group with electroacupuncture and the compound group without elec?troacupuncture, with 10 rats in each group. After a high fat and sugar diet for 4 weeks, the Wistar rats were given strepto?zotocin i. p. injection to establish models of type 2 diabetes mellitus. Renal hypertension was developed by the“2K1C” im?proved method to make unilateral renal artery ligation?induced renal artery stenosis. Then, electroacupuncture treatment was performed on the rats for 2 weeks except the compound group without electroacupuncture. The changes of values of BP, FBG, Cr, BUN, glycated hemoglobin, renin and Ang II were recorded and analyzed. Results The values of BP, FBG, Cr, BUN, glycated hemoglobin, renin and Ang II in the compound group with electroacupuncture showed a significant re?duction compared with the compound group without electroacupuncture after 2 weeks (P<0?01), but there was no obvious changes in the values of Cr and BUN(P>0?05). Conclusions The blood glucose and blood pressure in the rat model of compound group can be reduced to a normal level with continuous electroacupuncture at bilateral acupoints Zusanli, and it can also be kept at a stable level after single electroacupuncture for 2-3 days. The acupuncture therapy is more suitable for early clinical treatment and can be used in basic research with advantages of economic, safe, no side effect and so on.

OBJECTIVEThis study further explores the stromal cell-derived factor-1 (SDF-1)/chemokine receptor 4 (CXCR4) signaling axis mechanism in temporomandibular joint osteoarthritis (OA) by detecting the changes in CXCR4, interleukin (IL)-6, and collagen X expression in the ATDC5 cell line stimulated by the cyclic tensile strain and SDF-1.

METHODSInsulin-transferrin-selenium (ITS) was used to induce ATDC5 cells to differentiate into chondrocyte-like cells. After three weeks, the cells were divided into two groups: those with and without cyclic tensile strain. These groups were further divided into the negative control and SDF-1 groups. Strain force of 20% was applied. After 12 h, the total proteins were extracted from cells of the four groups, and Western blot analysis was used to detect the changes in CXCR4, IL-6, and collagen X expression.

RESULTSSDF-1 could enhance CXCR4, IL-6, and collagen X expressions in the chondrocytes, and 20% tensile strain force could further upregulate the three factors.

CONCLUSIONUnder abnormal tensile force, SDF-1 can upregulate its specific receptor CXCR4, thus increasing its-binding efficiency and resulting in the activation of the SDF-1/CXCR4 axis. This condition enhances the expressions of IL-6 and other inflammatory factors and directly damages to cartilage tissue. Such damage directly promotes chondrocyte hypertrophy, which enhances collagen X expression.

Oleanolic acid-precipitated calcium carbonate solid dispersion was prepared by using solvent evaporation method. The microscopic structure and physicochemical properties of solid dispersion were analyzed using differential scanning calorimetry and scanning electron microscopy (SEM). And its in vitro release also was investigated. The properties of the precipitated calcium carbonate was studied which was as a carrier of oleanolic acid solid dispersion. Differential scanning calorimetry analysis suggested that oleanolic acid may be present in solid dispersion as amorphous substance. The in vitro release determination results of oleanolic acid-precipitated calcium carbonate (1: 5) solid dispersion showed accumulated dissolution rate of.oleanolic acid was up to 90% at 45 min. Accelerating experiment showed that content and in vitro dissolution of oleanolic acid solid dispersion did not change after storing over 6 months. The results indicated that in vitro dissolution of oleanolic acid was improved greatly by the solid dispersion with precipitated calcium carbonate as a carrier. The solid dispersion is a stabilizing system which has actual applied value.

OBJECTIVETo explore clinical significance of rotational axis of distal femur on Chinese adults in total knee arthroplasty (TKA).

METHODSThere were 86 Chinese adults (106 normal knees) including 47 males (53 knees) and 39 females (53 knees), 54 knees were on left and 52 on right. The CT scan was employed in the distal femur. The scan direction was aligned to be on the plane perpendicular to the mechanical axis of the femoral. The CT images of cross sections across lateral and medial femoral epicondyle were moved to personal computer,lateral angle between anterior posterior line (APL) and surgical transepicondylar axis (STEA) (ATA),lateral angle between posterior condylar line (PCL) and APL (APA), angle between perpendicularity of APL and PCL (A-PA), posterior condylar angle (PCA), condylar twist angle (CTA), angle between clinical transepicondylar axis (CTEA) and STEA (CSA) were measured. These values were divided into different groups according to gender and side, the values of CTA, PCA, A-PA, angle PT (varus of tibia plateau), constant 3, ATA, APA and constant 90° were compared by statistically. A-PA and PCA, and CTA were analysed statistically with the liner regression, the relationship among CTEA, STEA ,PCL, APL and PLP were performed to assess by liner regression.

RESULTSATA was (89.79 ± 1.22)°, APA was (84.84 ± 1.83)°, A-PA was (5.16 ± 1.83)°, PCA was (4.80 ± 1.23)°, CTA was (8.23 ± 1.40), CSA was (3.45 ± 0.68)°. All the parameters had no differences on sex and side,but CSA had difference on male and female. There was no difference among angle PT, PCA, A-PA. There was significant difference in CAT, constant 30 and angle PT, PCA,A-PA. There was no difference between ATA and constant 90°, but there was difference between APA and constant 90°. There was relativity between PCA and CTA, and also PCA and A-PA, CTA and A-PA. There was significant relativity between STEA and CTEA, between STEA and APL, between STEA and PCL, and also between APLP, APL and PCL, but there was no significant relativity between PCL and CTEA.

CONCLUSIONTKA for Chinese, the section of femoral posterior condyle should be external 5° to obtain the optimum rotational orientation. The property is different entirely between STEA and CTEA, the rotational alignment is not performed according to parallel to the CTEA in distal femur. Among STEA, APL, PCL, the STEA is the most reliable mark ofrotational alignment of the distal femur, and the PCL is the less reliable mark.

Objective To assess the value of tumor marker immunostaining-FISH (TM-iFISH) technology on concen?trating and enumeration of tumor cells in CSF of lung cancer patients with leptomeningeal metastasis(LM). Methods Six cases of non-small cell lung cancer with leptomeningeal metastasis, which were diagnosed by CSF cytology or enhanced MRI scan, were selected. A total of 20 mL of CSF was collected in each case. TM-iFISH technology was employed to concen?trate and quantify circulating tumor cells in 7.5 mL CSF samples in each case while CSF cytology used 10 mL CSF samples in each case;Finally, the rest 2.5 mL CSF in each case was used for biochemistry assay. Results Ten CSF samples from 6 patients with non-small lung cancer with LM were assayed and tumor cells numbers ranging between 3 and 1 823 every 7.5 mL were found in 7 samples. On the other hand, CSF cytology examination only revealed tumor cells in 3 cases. Using CSF biochemical assay, higher than normal of protein level was found in 9 cases. TM-iFISH technology was employed again in 3 cases of patients who received treatment. Tumor cell count in CSF reduced in 2 out of the 3 cases. Conclusion TM-iFISH technology is a new method for detection and enumeration of tumor cells in the CSF in non-small cell lung cancer patients with leptomeningeal metastasis. This technology present diagnosis and curative values in lung cancer patients with leptomen?ingeal metastasis.

Objective:To investigate the effectiveness of immunoFISH technology in detecting tumor cells in cerebrospinal fluid (CSF) for adjuvant diagnosis of meningeal metastasis from lung cancer. Methods:Circulating tumor cells (CTCs) were detected by im-munoFISH technology in CSF samples from 16 patients with meningeal metastasis from lung cancer and 8 patients with non-tumorous brain diseases. Meningeal metastasis from lung cancer was diagnosed on the basis of neurological symptoms and confirmed by en-hanced magnetic resonance imaging and CSF cytological examination. Results:The number of CTCs was significantly greater in pa-tients with meningeal metastasis from lung cancer than in those with non-tumorous brain diseases (P<0.01). The critical point of the maximum correct diagnosis index (Youden index) was regarded as the judging criterion for the positive tumor cells in CSF based on the receiver operating characteristic curve. When one tumor cell existed in 7.5 mL of CSF, the area under the curve was 0.875, and the 95%confidence interval ranged from 0.705 to 1.000. The diagnostic sensitivity, specificity, effectiveness, positive predictive values, and neg-ative predictive values were 75.0%, 100.0%, 83.3%, 100.0%, and 66.7%, respectively. Conclusion:ImmunoFISH technology provides great significance in detecting CTCs in CSF to diagnose meningeal metastasis from lung cancer.
