OBJECTIVETo compare the differences in the clinical efficacy between Guan's quadruple therapy for kidney disease and the conventional western medication in the treatment of chronic renal failure (CRF).

METHODSEighty patients were randomized into an observation group and a control group, 40 cases in each one. In the observation group, besides the physician instruction of low protein and low phosphorus diet in the two groups, Guan's quadruple therapy for kidney disease was applied, including (1) the isolated herbal moxibustion at Shenshu (BL 23) and Pishu (BL 21), or Ganshu (BL 18), Zusanli (ST 36) and Guanyuan (CV 4) alternatively; (2) acupuncture at the auricular points such as shen (CO10), jiaogan (AHR6), Shenshangxian (TG2), fei (CO14) and pizhixia (AT4); (3) injection of mixture of astragalus injection and lidocaine injection at Feishu (BL 13), Pishu (BL 21), Shenshu (BL 23) and the others; (4) modified Shenshuai Yihao decoction according to syndrome differentiation. In the control group, the conventional western medication was used. After 6 months of treatment, the differences were observed between the two groups in the clinical efficacy, serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine (Ccr) and 24 h urine protein quantitation (UPQ).

RESULTSIn the observation group, after treatment, the remarkably effective rate was 50.0% (20/40) and the total effective rate was 82.5% (33/40), which were superior to 25.0% (10/40) and 45.0% (18/40) in the control group (both P < 0.05). After treatment, the levels of Scr, BUN and 24 h UPQ were reduced apparently (all P < 0.05), and the level of Ccr was increased apparently in the two groups (both P < 0.05). After treatment, the levels of Scr, BUN and 24 h UPQ were reduced much more apparently in the observation group as compared with those in the control group (all P < 0.05).

CONCLUSIONGuan's quadruple therapy for kidney disease achieves a better efficacy on CRF compared with the conventional western medication. This therapy improves renal functions, relieves clinical symptoms and physical signs and benefits the life quality of patients.

OBJECTIVETo evaluate the expression of CD4+, CD8+ T cells and cell apoptosis in oral lichen planus (OLP) and investigate the role and the relationship of immunological reaction and cell apoptosis in the pathogenesis of OLP2.

METHODSImmunohistochemical technique was used to study the expression of CD4+, CD8+ T cells in 27 OLP cases. TUNEL was used for detecting the cell apoptotic index (AI) in 17 OLP2 cases.

RESULTSThe expression of CD4+, CD8+ T cells were obviously elevated in lamina propria of OLP group compared with control group (P<0.05). There was a strong significance when compared the ration of CD4/CD8 in both group. AI was remarkably increased in epithelia cells and significantly decreased in lymphocytes in lamina propria in OLP cases compared with its expression in the control group respectively.

CONCLUSIONThe increased amount of CD4+, CD8+ T cells in lamina propria of OLP and the change ration of CD4/CD8 suggest that immune response is involved in the pathogenesis of OLP. The abnormal cell apoptosis plays an important role in the pathogenesis of OLP.

Objective To investigate the differences of X-ray findings of skeletal fluorosis between coal-burning type endemic fluo-rosis and industrial fluorosis.Methods The patients were randomly selected as research objects including 60 cases of coal-burning type endemic osteofluorosis and 60 cases of industrial osteofluorosis.The X-ray findings on the left forearm,crus and pelvic radio-graphs of these patients were analyzed retrospectively to find out the differences between skeletal fluorosis of coal-burning type endemic fluorosis and industrial fluorosis.Results X-ray features are no significant statistical differences between coal-burning type endemic fluorosis and industrial fluorosis,except these of interosseous membrane ossification of forearm and crus (forearmχ2=10.909,P<0.05;crusχ2=8.547,P<0.05),obturator membrane ossification of pelvis (χ2=36.554,P<0.05),periosteal proliferation outside bone of crus (χ2=4.937,P<0.05),and ossification of soleus (χ2=4.904,P<0.05).Conclusion The X-ray signs of endemic osteofluorosis and industrial skeletal fluorosis are almost similar,but there are some differences between them.

OBJECTIVETo examine the expression of TGF-beta1, Smad7 and cell apoptosis in oral lichen planus (OLP) and to evaluate the possible pathogenesis of oral lichen planus.

METHODSImmunohistochemical technique was used to study the expression of TGF-beta1 and Smad7 in the epithelia cells of 17 OLP cases and 7 normal oral mucosa (NOM). TUNEL was used for detecting the cell apoptosis in 17 OLP cases and 7 NOM.

RESULTSTGF-beta1 was moderately positive in the epithelia cells of OLP. All the epithelia cells in OLP showed strong cytoplasmic staining. The expression of TGF-beta1 and Smad7 were significantly increased in OLP compared with that in NOM (P < 0.05). Cell apoptotic index (AI) was remarkably increased in epithelia cells in OLP cases, and the cell apoptosis was localized in basal and suprabasal epithelial layers. There was a positive correlation between TGF-beta1 expression and cell apoptosis in the epithelia of OLP (r = 0.69, P <0.05).

CONCLUSIONSHigh expression of TGF-beta1 and Smad7 in the epithelia of OLP suggests that TGF-beta1-Smad7 signal pathway was disturbed in oral lichen planus. The imbalance of TGF-beta1-Smad7 pathway may contribute to the mechanisms of cell apoptosis of epithelial cells in OLP.

BACKGROUNDMany studies suggest that the gamma irradiation decreases allograft strength in a dose-dependent manner. However, no study has demonstrated that this decrease in strength translates into higher failure rate in meniscal allograft transplantation (MAT). The aim of this study was to investigate the effects of gamma irradiation on macroscopic and histological alterations of transplanted meniscal tissue and joint cartilage after MAT.

METHODSMedial total meniscectomies were performed on the right knees of 60 New Zealand white rabbits. All meniscal allografts were divided into three groups (20 in each group) and then sterilized with 0 Mrad, 1.5 Mrad, or 2.5 Mrad of gamma irradiation. For each group, 5 menisci were randomly chosen for scanning electron microscopic (SEM) analysis and the remaining 15 were prepared for MAT surgeries. Forty-five right knees received MAT surgeries (0 Mrad group, 1.5 Mrad group, 2.5 Mrad group, 15 in each group), whereas the remaining 15 only received medial meniscectomy (Meni group). The left knees of the Meni group were chosen as the Sham group (n = 15). All the rabbits were sacrificed at week 24 postoperatively. Cartilage of the medial compartment of each group was evaluated macroscopically using the International Cartilage Repair Society (ICRS) score and then histologically using the Mankin score based on the Masson Trichrome staining.

RESULTSThe SEM analysis confirmed that the meniscal collagen fibers would be significantly damaged as the dose of gamma irradiation increased. At week 24, the overall scores of macroscopic evaluations of the transplanted meniscal tissue showed no significant differences among the three groups receiving MAT surgeries, except for 2 in the 2.5 Mrad group presented partial radial tears at midbody. The ICRS scores and the Mankin scores showed the lowest in the Sham group and the highest in the Meni group (P < 0.05). For the three groups receiving MAT surgeries, the 2.5 Mrad group showed significant higher ICRS scores and Mankin scores than both the 0 Mrad group and the 1.5 Mrad group (P < 0.05). Whereas the 1.5 Mrad group presented similar results to the 0 Mrad group concerning both the ICRS scores and the Mankin scores.

CONCLUSIONSThe current in vivo animal study proved that although the meniscal collagen fibers were damaged after gamma irradiation, the failure rate of MAT surgeries might not significantly increase if the irradiation dose was <1.5 Mrad for New Zealand white rabbits.

OBJECTIVE: To explore the effect of bizhongxiao decoction (BZXD) on the protein maps of BZXD-treated synovitis of collagen-induced arthritis (CIA) in rats in 2-dimensional gel electrophoresis (2-DE), and to provide new clues for illuminating the active mechanism of BZXD in treating the rheumatoid arthritis (RA). METHODS: Seventy SD rats were randomly divided into nor- mal group, model group and BZXD group. The experimental arthritis rat model was established by subcutaneouly injecting Type II collagen and complete Freunds adjuvant. The total proteins of synovial tissue of rat joints in the normal group, model group and BZXD group were seperated by 2-DE respectively. The gels of the 3 groups were stained by Coomassie brilliant blue. Electron pictures were obtained by scanning the gels, and then the differential proteins among the normal group, model group and BZXD group were examined by comparing the spots density volume in the gels. The electrophoregrams of the gels were analyzed in Pdquest software. RESULTS: The incidence of arthritis in the rats was approximately 88%. The 2-DE maps of rat synovial tissue in the normal group, model group and BZXD group were well duplicated. The average protein spots in the normal group, model group and BZXD group were 947 +/- 39, 994 +/- 41, and 1031 +/- 52, and the match rates were 92%, 91%, and 94.2% respectively. The average deviations of spot position were (0.896 +/- 0.217) mm in isoelectric focusing (IEF) and (1.102 +/- 0.104) mm in sodiumdo-decylsufate-polyacrylamide gel electrophoresis (SDS-PAGE), respectively. Three hundred twenty-eight differential proteins were observed between the model group and BZXD group, of which 174 were up-regulated, 147 were down-regulated in the BZXD group, and 7 proteins were expressed only in the model group. One hundred ninty-three differential proteins were displayed between the model group and the normal group, of which 123 proteins were up-regulated and 70 were down-regulated in the model group. CONCLUSION 2-DE protein expression profiles of synovial tissue in CIA rats are established, and many differential proteins are discovered. Further analysis on the differential proteins may serve as a new method to study the moleculer mechanism of BZXD in treating the rheumatoid arthritis.

Objective:To investigate characteristics and differences of cerebral glucose metabolism in patients with anti- N-methyl- D-aspartate receptor (NMDAR) encephalitis from the perspective of different trigger factors of antibodies. Methods:A total of 15 patients (8 males, 7 females, age (30.5±17.7) years) with anti-NMDAR encephalitis between January 2016 and January 2019 in Huashan Hospital, Fudan University were recruited retrospectively. All patients underwent resting state cerebral 18F-FDG PET imaging. The characteristics of brain glucose metabolism were analyzed, and the SUV ratio (SUVR) was semi-quantitatively compared with that in 12 healthy subjects (HS; 7 males, 5 females, age (51.5±9.6) years). Independent-sample t test was used to analyze the data. Results:Among 15 patients, 5 patients were viral encephalitis-related anti-NMDAR encephalitis, showing focal decreased metabolism in unilateral temporal lobe or basal ganglia (SUVR: patients: 0.659±0.219; HS: 1.754±0.203; t=-9.58, P<0.001), with increased metabolism in contralateral temporal lobe or basal ganglia (SUVR: patients: 2.275±0.244; HS: 1.960±0.227; t=2.55, P=0.022) in 18F-FDG PET imaging. Six patients were cryptogenic anti-NMDAR encephalitis, showing asymmetric increased metabolism in frontal, temporal, parietal and basal ganglia (SUVR: patients: 2.482±0.395; HS: 1.754±0.203; t=5.23, P<0.001), with decreased metabolism in bilateral occipital lobes. The remaining 4 cases were paraneoplastic origin accompanied by teratoma, showing increased metabolism in bilateral temporal and basal ganglia (SUVR: patient: 2.359±0.181; HS: 1.960±0.227; t=3.16, P=0.007), with mild decreased metabolism in bilateral occipital lobe. Conclusions:The abnormal changes of cerebral glucose metabolism in patients with anti-NMDAR encephalitis can be divided into at least three patterns according to different trigger factors. A comprehensive understanding of these characteristic metabolic changes is helpful for detecting disease, and may provide potential value in indicating different causes.
