Quantitative models were established to analyze the content of chlorogenic acid and soluble solid content in the liquid-liquid extraction of Reduning injection by near-infrared (NIR) spectroscopy. Seven batches of extraction solution from the liquid-liquid extraction of Lonicerae Japonicae Flos and Artemisiae Annuae Herba were collected and NIR off-line spectra were acquired. The content of chlorogenic acid and soluble solid content were determined by the reference methods. The partial least square (PLS) and artificial neural networks (ANN) were used to build models to predict the content of chlorogenic acid and soluble solid content in the unknown samples. For PLS models, the R2 of calibration set were 0.9872, 0.9812, RMSEC were 0.1533, 0.7943, the R2 of prediction set were 0.9837, 0.9733, RMSEP were 0.2464, 1.2594, RSEP were 3.25%, 3.31%, for chlorogenic acid and soluble solid content, respectively. For ANN models, the R2 of calibration set were 0.9903, 0.9882, RMSEC were 0.0974, 0.4543, the R2 of prediction set were 0.9868, 0.9699, RMSEP were 0.1920, 0.9427, RSEP were 2.61%, 2.75%, for chlorogenic acid and soluble solid content, respectively. Both the RSEP values of chlorogenic acid and soluble solid content were lower than 6%, which can satisfy the quality control standard in the traditional Chinese medicine production process. The RSEP values of ANN models were lower than PLS models, which indicated the ANN models had better predictive performance for chlorogenic acid and soluble solid content. The established method can rapidly measure the content of chlorogenic acid and soluble solid content. The method is simple, accurate anc reliable, thus can be used for quality control of the liquid-liquid extraction of Reduning injection.

OBJECTIVETo evaluate the clinical outcome of reconstruction of maxillary defects with vascularized iliac crest flap and simultaneous osseointegrated implant embedding.
METHODSDuring September to October 2003, two patients with maxillary defects from tumor resection underwent microsurgical reconstruction. The free iliac osteomuscular flap transferring and simultaneous osseointegrated implant embedding were performed to repair the defects. Three months after the reconstructive surgery, an abutment operation was preformed and denture was applied in both cases.
RESULTSThe flaps survived well. Postoperative follow-up for 8 to 9 months showed that the patients obtained good zygomaxillary appearance, normal occlusion, and satisfactory pronunciation, without oronasal fistula or other serious complications.
CONCLUSIONSThe free iliac crest osteomuscular flap with simultaneous osseointegrated implant embedding is an ideal, effective and cosmetically acceptable method for maxilla reconstruction.

OBJECTIVETo investigate the changes of thyroxin and monocyte human leukocyte antigen-DR expression in senior patients with sepsis and explore their clinical significance.
METHODSAccording to the 2001 SCCM/ESICM/ACCP/ATS/SIS international sepsis definitions, 125 senior patients with sepsis free of thyroid conditions were divided into non-severe sepsis group (n=86) and severe sepsis group (n=39), with another 30 healthy subjects as the control. Thyroid function was assayed by chemoluminescence method in these patients and monocyte HLA-DR expression was determined by flow cytometry.
RESULTSCompared with the control group and non-severe sepsis cases, the levels of free T3 (FT3), free T4 (FT4), T3, T4 and monocyte HLA-DR expression were significantly lower in severe sepsis cases (P<0.05), but the levels of thyroid stimulating hormone (TSH) were comparable between the 3 groups (P>0.05). The non-severe sepsis cases showed significantly lower levels of FT3, FT4, T3, T4, TSH and monocyte HLA-DR expression than the control group (P<0.05). In severe sepsis group, the levels of FT3, FT4, T3, T4 and monocyte HLA-DR expression showed significant differences between the fatal cases and surviving cases (P<0.05).
CONCLUSIONThe levels of thyroxin and monocyte human leukocyte antigen-DR expression are obviously lower in senior patients with severe sepsis, and their detection may well indicate the severity of the condition and help make prognostic judgment.

Objective: To explore the relevant gene, signaling pathway for permanent atrial fibrillation (pAF) occurrence in order to provide the molecular basis of the pathogenesis of pAF. Methods: Our research included in 2 groups: pAF group, n=7 patients and Control group, n=4 healthy subjects with sinus rhythm. Agilent 4x44K microarray was used to analyze the mRNA in left atrium for differential gene expression profile. Based on Gene Ontology, KEGG and Biocarta databases, differentially expressed genes were studied for their relevant function and signaling pathway. Furthermore, the genes with significant differences were verified by quantitative real time PCR (qRT-PCR) in pathological specimen from 5 pAF patients and 5 normal heart donors. Results: The expression profile identified 987 abnormally expressed genes, 567 of them were down-regulated and 420 were up-regulated. 9 genes with significant differences were verified by qRT-PCR in pathological specimen and the changes were similar to microarray; those genes were closely related to pAF by involving left atrium fibrosis, electrical remodeling, inflammation, cellular stress response, metabolism and transcription regulation. GO and Pathway analysis indicated that down-regulated genes were mainly involved in metabolic processes; up-regulated genes had the effects on cellular stress response, immune response and platelet activation. Conclusion: Microarray technology identified some important genes related to pAF occurrence; such genes involved in left atrial structural and functional remodeling via affecting cellular metabolism, inflammation, immune response and thrombogenesis in relevant patients.

BACKGROUNDThe benefit of neoadjuvant chemotherapy in the management of head and neck squamous cell carcinomas (HNSCC) still remains controversial. The aim of this meta-analysis is to evaluate the role of the neoadjuvant chemotherapy with the cisplatin and fluororacil (PF) regimen in enhancing the overall survival of and decreasing locoregional relapse and distant metastasis in HNSCC patients.
METHODSMedline and manual searches were performed to identify all published randomized controlled trials (RCTs) investigating the efficacy of the neoadjuvant chemotherapy with the PF regimen. Outcomes assessed by meta-analysis included locoregional relapse, distant metastasis, and overall survival. The odds ratio was the principle measurement of effect, which was calculated as the treatment group (chemotherapy plus locoregional treatment) versus the control group (locoregional treatment alone) and was presented as a point estimate with 95% confidence intervals (CI).
RESULTSEight RCTs were adopted for analysis. The meta-analysis showed that the odds ratio for the locoregional relapse was 0.92 (0.70 - 1.22, 95% CI), which was not statistically significant. The odds ratios for distant metastasis and overall survival were 0.47 (0.33 - 0.68, 95% CI) and 1.28 (1.01 - 1.62, 95% CI) respectively, which were both statistically significant.
CONCLUSIONSNeoadjuvant chemotherapy with the PF regimen in HNSCC patients has no effect on locoregional relapse. However, it shows a small but significant benefit in reducing distant metastasis and improving the overall survival.

OBJECTIVETo analyze the clinical characteristics of living-related kidney transplantation (LRKT).
METHODSFrom January, 2004 to December, 2008, 175 LRKT were performed including 63 cases (36%) of parent-child relations and 49 cases (28%) of sibling relations between the recipients and donors. Out of 175 donors, 52 were 50 years old or above, 4 had microscopic hematuria (including 2 with also hypertension), 2 had kidney stone, and 2 had high body mass index (BMI). Zero-point graft biopsy was performed in 59 donors, and abnormalities were found in 15 of them. The recipients were at the age of 33-/+10.5 years, and the primary diseases are mainly dominant glomerular nephritis (72.6%, 127/175), and with a few cases of diabetes (4%, 7/175) and hypertensive nephropathy (4%, 7/175).
RESULTSSerum creatinine of the donors was 102-/+22.5 micromol/L at 7 days postoperatively, and 92-/+19.1 micromol/L at one month. One recipient died of severe pulmonary infection. Two recipients underwent graft nephrectomy due to anastomotic stenosis with concomitant acute graft rejection and renal arterial embolism. The one-year survival rates of the patients and grafts were 99.3% and 98.2%, respectively. The incident rates of accelerated rejection and acute rejection were 1.1% and 14.9%, respectively. Other complications included impaired liver function (22.3%), infection (9.7%) and leucopenia (4.6%). The renal arterial stenosis occurred in 2.3% (4/175) of the recipients.
CONCLUSIONSThe recipients of living-related and cadaveric kidney transplant have different primary kidney disease spectrums. Differential diagnosis and treatment of acute rejection and renal artery or anastomotic stenosis can be of vital importance. Marginal donor kidneys with appropriate inclusion criteria can be safely used for transplantation. With good short-term patient and graft survival, LRKT needs further study to evaluate its long-term effect.

OBJECTIVETo study the anatomy characters of renal artery and the treatment of multiple arteries in living donor renal grafts.
METHODSRecords of 142 living donors were analyzed in our center. We analyzed the anatomic structure of renal arteries by DSA and CTA pre-transplantation. Thirty-one kidneys with multiple arteries were transplanted after reconstruction. Then clinical effects were compared between multiple-renal-arteries group (n=31) and single-renal-artery group (n=111).
RESULTSThe incidence of multiple renal artery was 30.99%, and there was no difference between both sides (left kidney 22.54%, right kidney 22.13%). If the multiple artery occurred in left or right kidney, the incidence of the multiple artery occurred in the other side was 56.25% and 60.00%, respectively. The diameter of left main renal artery was more magnanimous (P=0.001) and the first branch was more closed to abdominal aorta (P=0.004). Operation time and warm/cool ischemia time were longer in the multiple-renal-arteries group. However, estimated blood loss, delayed graft function, acute rejection and flow rate of arcuate artery were similar in both groups, the same as serum creatinine and serum creatinine clearance rate on day 7, 1 month and 3 month post-operation. It was shown by repeated measures ANOVA that graft with multiple arteries didn't affect the tendency of renal function at early time post-operation.
CONCLUSIONComprehending the character of renal artery and accurate treatment of multiple artery anastomosis are critical for the effect of the living kidney transplantation.
