"Mistreatment by warming therapy" refers to various symptoms/syndromes caused by improper use of fire methods mentioned in Treatise on Febrile Diseases, which are similar to damaged yin induced fire-heat syndrome (injury of yin, consumption of qi, loss of yin, consumption of body fluid) manifested after radiotherapy and/or chemotherapy in modern clinics. Better efficacy was obtained in treating various symptoms/syndromes by using nourishing yin purging fire method. In this paper authors focuses on exploring guiding significance of using "Mistreatment by warming therapy" in treating non-small cell lung cancer (NSCLC).

Background and purpose:Neoadjuvant chemotherapy is one of the hot studied area in breast cancer research.Our aim was to explore the relationship between the clinical effect,pathological changes and the neoadjuvant chemotherapy containing THP and docetaxel on breast cancer.Methods:The expression of ER, PR and CerbB-2 in breast cancer tissue of patients who had received neoadjuvant chemotherapy were detected by immunohistochemistry method.The relationship of age,ER,PR,CerbB-2,pathological stage and axillary lymph node metastasis with pathological complete response(pCR) was analysed.Results:For the patients after neoadjuvant chemotherapy,the pCR of the positive ER(0%),PR(9.38%) was lower than that of negative ER(20.27),PR(90.63%) respectively.The pCR of the positive CerbB-2(33.33%) was higher than that of negative CerbB-2(9.74%,P

Objective:To investigate the quantification of CD4~+CD25~+ regulatory T cells and distribution of CD4~+CD8~+ T lymphocyte subgroup in peripheral blood of patients in chronic hepatitis B (CHB),and to reveal relationship between CD4~+CD25~+ regulatory T cells,CD4~+CD8~+ T lymphocyte subgroup and HBV infetion as well.Methods:CD4~+CD25~(high),CD4~+CD25~+Foxp3~+Treg and CD3~+CD4~+CD8~+T lymphocyte subgroup in peripheral blood from 50 patients with CHB and 20 healthy controls was analyzed using flow cytometry.HBV DNA was detected by fluorescence quantitative PCR.Results:The number of CD4~+CD25~(high)Tregs in patients with CHB was obviously higher than that in healthy controls(P＜0.01)and increased with copies of HBV DNA.The same with the change of CD4~+CD25~+Foxp3~+Tregs in patients with CHB and there was a positive correlation between CD4~+CD25~(high)Tregs and CD4~+CD25~+Foxp3~+Tregs(r=0.890,P＜0.001).Compared with healthy controls,the frequency of CD4~+T cells and the ratio of CD4~+/CD8~+ in patients with CHB was declined,but there was no significant difference in the frequency of CD3~+T cells and CD8~+T cells between them(P＞0.05).The variation in the number of CD4~+CD25~(high)Tregs was correlated positively with the copies of HBV DNA(r=0.782,P＜0.001)and glutamic-pyruvic transaminase(ALT)(r=0.432,P＜0.005)separately,but negatively with the frequency of CD3~+,CD4~+,CD8~+T cells and the ratio of CD4~+/CD8~+(P＞0.05).The variation in the frequency of CD3~+,CD4~+,CD8~+T cells and the ratio of CD4~+/CD8~+ was also correlated negatively with the copies of HBV DNA(P＞0.05).Conclusion:The number of CD4~+CD25~(high)Tregs increases in patients with CHB and is in accordance with the copies of HBV DNA and increased level of ALT.Further studies should be done to investigate weather CD4~+CD8~+ T lymphocyte subgroup could be used to monitor the state of community.

OBJECTIVETo observe the intervention and mechanism of Qushi Huayu Recipe (QHR) on gene expression profiles in high lipid diet induced fatty liver rats.

METHODSFatty liver model was prepared in 20 male SD rats using single high fat diet (88% common forage +2% cholesterol +10% lard). Four weeks after modeling they were divided into the model group and the QHR group according to random digit table, 10 in each group. QHR (at 0. 93 g crude drug/100 g body weight) and distilled water was respectively to rats in the QHR group and the model group by gastrogavage while modeling, once per day. Meanwhile, 10 SD male rats were recruited in a normal group, administered with equal volume of distilled water by gastrogavage. At the end of week 8 all rats were sacrificed, and blood and livers were collected for subsequent analysis. Contents of liver triglyceride (TG) and free fatty acid (FFA) , activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected using biochemical assay. Pathological changes of liver tissue were observed using H&E and oil red O stain. Liver gene expressions were detected by Affymetrix gene expression profiles. Differentially expressed genes were compared between the QHR group and the model group, functions of differentially expressed genes and signal pathways involved analyzed. Ten differentially expressed genes involved in glycolipid metabolism with fold change more than 2 were selected for verification by real-time PCR.

RESULTS(1) Compared with the normal group, contents of liver TG and FFA, and serum activities of ALT and AST obviously increased in the model group (P <0. 01). Compared with the model group, contents of liver TG and FFA, and activities of ALT and AST obviously decreased in the QHR group (P <0. 05, P <0. 01). QHR could reduce high fat induced fatty degeneration of liver cells , alleviate inflammation, and improve pathological changes of liver tissue. (2) Compared with the model group, there were 80 differentially expressed genes (with fold change > 2, P < 0.05) with clear functions and appointed gene names, including 44 up-regulated and 36 down-regulated genes. Eighty genes were involved in 27 signal pathways with statistical difference, including glycerolipid metabolism, adipocytokine signaling pathway, insulin signal pathway, drug metabolism signal pathway, etc (P < 0.05). (3) RT-PCR results of 10 glycolipids metabolism regulating genes such as Gk, Scd1, Gpat2, G6pc, Irs1, and so on showed that all RT-PCR genes were completely coincide with up-regulated or down-regulated tendency in results of gene chips. 80% genes had approximate fold change.

CONCLUSIONQHR could regulate gene expressions related to fat metabolism, carbohydrate metabolism, anti-lipid peroxidation, and drug metabolism in high fat diet induced fatty liver rats, and its comprehensive pharmacological actions could be manifested.

The average score of methodology quality was (24.65±3.97), no literature met all required items, and the major problems were as lack of“a priori design”, insufifcient and bias of data selection combining inappropriate data synthesis. The average score of report quality was (17.20 ± 2.90), no literature met all 27 required items, and the major problems were as incomplete report of abstract, objective, protocol and registration, incomplete data collection/analysis, using and publishing bias information, incomplete quality assessment.
Conclusion: Both of methodology and report of meta-analysis for CAD prevention and treatment have quality problems at different levels, further improvement should be expected.

OBJECTIVETo investigate the anti-hypoxia and anti-oxidation effects of aminophylline on human with acute high-altitude exposure.

METHODSTotally 100 young male army members newly recruited from Sichuan province (400 meters above sea level) were enrolled. They were randomly divided into two groups: 50 in aminophylline group (A group) and 50 in control group (C group). A group and C group orally took aminophylline and placebo respectively for 10 days, 7 days before entering Lhasa (3 658 meters above sea level) by air and 3 days after it. Several parameters were measured at three time points: before drug taken, 7 days after drug taken, and 3 days after ascending high altitude. These parameters included serum levels of nitric oxide (NO), superoxide dismutase (SOD), catalase (CAT), hydrogen dioxide (H2O2), lactic acid (LA), as well as arterial oxygen saturation (SO2), arterial oxygen partial pressure (PaO2), and arterial carbon dioxide partial pressure (PaCO2). Statistical analysis was conducted to compare the difference between two groups with Stata 7.0 software system.

RESULTSThere were no statistical differences between groups in hypoxia and oxidation indicators before and after drug taken in plain area. Three days after ascending high altitude, the serum levels of SOD, CAT, H2O2, LA, PaCO2 increased in both groups, yet to a much larger degree in C group than A group (P < 0.01); and NO, SO2, PaO2 decreased more markedly in C group (P < 0.05 for NO, P < 0.0001 for SO2 and PaO2).

CONCLUSIONAminophylline has significant anti-hypoxia and anti-oxidation effects at high altitude.

OBJECTIVETo compare the pathologic diagnosis and immunohistochemistry of small cell malignant tumors (SCMT) of bone using both core needle biopsy and surgical specimen.

METHODSSeventy-seven cases of SCMT with core needle biopsies and surgical specimens available were respectively analyzed by histologic examination and immunohistochemical study, with literature review.

RESULTSThe male-to-female ratio was 48:29. The age of the patients ranged from 6 to 73 years. The tumors studied included Ewing sarcoma/PNET (n = 38), myeloma (n = 23), lymphoma (n = 10), small cell osteosarcoma (n = 2), small cell carcinoma (n = 2) and mesenchymal chondrosarcoma (n = 2). The tumors involved limbs, axial skeleton and flat bones. Microscopically, the tumors shared similar histology, with small round cells and spindly cells arranged in diffuse sheets. The pathologic diagnosis by core needle biopsies correlated with that by surgical specimens in 84.4% (65/77) of the cases.

CONCLUSIONSSCMT represents a heterogeneous group of malignancy. Correlations with clinicoradiologic findings and application of ancillary investigations including immunohistochemistry and molecular study are important for definitive diagnosis. Pathologic diagnosis using core needle biopsies shows good results and provides useful information for surgical planning.

OBJECTIVETo explore the differential proteomic expression in human liver cells L-02 induced by different dosages of trichloroethylene (TCE).

METHODSHuman liver cells L-02 were treated with different concentrations of TCE and the solvent control (dimethylsulfoxide). The total cellular proteins were separated using 2DE and visualized with silver staining after TCE treatment. The images were analyzed with Image Master 2D Platinum 5.0 analysis software. The differentially expressed protein spots were identified by matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-TOF-MS).

RESULTSFifteen protein spots with significant difference were found, and went upward or downward or disappeared after the stimulation of TCE with different dosages, which indicated that TCE induced the change of the proteomic expression in the liver cells. The mass spectrum identification and the IPI human database retrieval were used for identifying 9 proteins related to the L-02 Liver cells induced by TCE.

CONCLUSIONThe result provides an insight to TCE-related molecular mechanism and which might be useful for further study of the TCE-associated proteins and molecular markers.

OBJECTIVETo analyze the dynamic changes in hepatitis B virus (HBV) DNA and hepatitis B surface antigen (HBsAg) levels in chronic hepatitis B (CHB) patients following treatment by antiviral nucleotide drugs over a 5-year follow-up period and to assess the clinical significance of quarterly and annual quantitative measurements.

METHODSOne-hundred-and-ten patients with CHB were enrolled in the study and administered on-going standard mono-therapy with various antiviral nucleotide drugs. Over a 5-year period, the HBV DNA level was measured by quantitative PCR every three months and the HBsAg levels were measured by chemiluminescence once a year. The dynamic changes in HBV DNA and HBsAg levels were assessed by Chi-squared test and ANOVA.

RESULTSOnly 90 of the CHB patients completed the 5-year follow-up and were included in the analysis. The patients who showed HBeAg-positivity at baseline (study start) had higher levels of HBV DNA and HBsAg than the patients showing HBeAg-negativity. In general, the antiviral nucleotide drug therapy induced downward trends in HBsAg and HBV DNA level over time (F = 17.1, 151.53, all P less than 0.05). However, the most robust reduction in HBV DNA occurred during the first year. The HBsAg level followed an opposite trend, with the most robust reductions occurring in the 3rd, 4th and 5th years of treatment.

CONCLUSIONLong-term antiviral nucleotide mono-therapies induced decreases in HBV DNA and HBsAg levels in CHB patients, with the former being most reduced in the short-term and the latter in the long-term.

OBJECTIVETo study the feasibility and safety of laparoscopic surgery for middle or low rectal cancer.

METHODS83 patients with middle or low rectal cancer received laparoscopic surgery and 85 patients received conventional open surgery. The cutting edge of specimens and number of lymph nodes were analyzed retrospectively.

RESULTSThe mean distance between resected margin and the tumor was 3.21 +/- 1.25 cm in laparoscopic operation group, while it was 1.15 +/- 1.11 cm in the open surgery group (P = 0.001). The mean number of disected lymph nodes was 12.53 +/- 1.88 in the laparoscopic operation group and 10.85 +/- 1.81 in the open operation group (P = 0.01). The incidence of postoperative complications was 12.0% in the laparoscopic operation group and 23.5% in the open operation group (P = 0.026). The mean time of food intake and using analgesics after surgery were 2.43 +/- 1.06 days and 2.53 +/- 1.01 days, respectively, in the laparoscopic operation group, while the corresponding figures were 3.67 +/- 1.13 days and 4.55 +/- 1.78 days, respectively, in the open operation group (P = 0.005, P = 0.008).

CONCLUSIONLaparoscopic surgery is a safe and effective procedure for middle or low rectal cancer, with less postoperative complications and better recovery after treatment.
