Objective:To investigate the therapeutic effect of carbon dioxide laser tonsillectomy.Method:In this prospective,randomized study, One hundred and two patients were divided into laser group or control group. Patients of laser group were cured with carbon dioxide laser tonsillectom,and the control group was cured with routine method. All operations are executed by one person. Observation index included operation time, hemorrhage in operation, ache after operation, inflammatory reaction of raw surface, repair time of raw surface, rehaemorrhagia and scar.Result:Laser group had advantages of less operation time, less hemorrhage, less ache and less inflammatory reaction of raw surface. Laser group have hemorrhage in operation (7.2±2.1)ml, while control group have hemorrhage in operation (92.0±35.0)ml. Laser group have pseudomembrane early but desquamate late.Conclusion:Carbon dioxide laser tonsillectomy is effective to relieve pain, inflammatory reaction and with less time ,it's an safe , efficient and mini-trauma operation.

Objective: To observe the effect of mFOLFOX7 protocolon advanced gastric cancer. Methods: Forty-eight patients with advanced gastric cancer were randomly divided into two groups: conventional treatment group (24 cases, surgery-adjuvant chemotherapy)and synthesized treatment group (24 cases, mFOLFOX7 neoadjuvant chemotherapy-surgery-adjuvant). The effect and toxic reaction of mFOLFOX7 on the patients with advanced gastric cancer were observed, and the R0 resection rate, complications incidence, survival rate were compared between two groups. Results: In synthesized treatment group, total effective rate was 58.3% . Fourteen patients (58.3%)achieved R0resection in synthesized group were compared with 7 patients (29.2%)achieved R0 resection in conventional group (P0.05).Conclusion: mFOLFOX7 neoadjuvant chemotherapy protocol is low toxic reaction. It can improve R0 resection rate of advanced gastric cancer, complications correlated with surgery are not increased. But it can’t improve the survivalrate.

OBJECTIVETo observe mainfestations of syndrome and biochemical indices of hypertensive model rats with excessive accumulation of phlegm-dampness syndrome (EAPDS), and to explore its possible pathological mechanism.

METHODSEAPDS rat model was prepared in 50 Wistar rats by feeding with high fat forage. Meanwhile, a normal control group consisting of 10 Wistar rats was set up by feeding with normal forage. After 25-week continuous feeding, 22 rats with body weight (BW) and blood pressure (BP) exceeding 25% those of the control group were selected as a model group. BW, BP, blood lipids, and related serological indicators were detected in all rats. Morphological changes of target organs were observed. mRNA expression levels of leptin receptor (LepR), Janus kinase2 (Jak2), signal transducer and activator of transcription 3 (Stat3), suppressor of cytokine signaling-3 (Socs3), angiotensin II receptor type 1 (AT1), angiotensin II receptor type 2 (AT2), phosphatidylinositol 3 kinase (P13K), serine threonine kinase (Akt), nuclear factor of kappa B (NF-κBp65), inhibitor of nuclear factor kappa-B kinase α (IKKα), NF-kappa-B inhibitor β (lKKβ), NF-kappa-B inhibitor α (IKBα), and AMP-activated protein kinase (AMPK) were detected by quantitative real-time PCR (qPCR). Expression levels of AT1 and LepR in aorta were detected by immunohistochemical assay and Western blot respectively.

RESULTSCompared with the control group, BW, BP, and blood lipids increased; serum levels of leptin (Lep) , Ang II, Hcy, ET-1, TNF-α, IL-6, and p2-MG increased, but NO decreased in the model group (P < 0.05, P < 0.01). Aortal endothelial injury and smooth muscle cell proliferation occurred in the model group, accompanied with heart and renal injury. Compared with the control group, mRNA expression levels of LepR, Jak2, Stat3, Socs3, AT1 , PI3K, Akt, NF-κB p65, IKKβ, IKBα, and AMPK in aorta were up-regulated significantly (P < 0.05), while the expression of IKKa decreased (P < 0.05). Immunohistochem- ical staining showed, brownish yellow deposit of AT1 and LepR was obviously increased, with more extensively positive distribution. Western blot results showed, as compared with the control group, protein expression levels of AT1 and LepR obviously increased in the model group (P < 0.05).

CONCLUSIONSModel rats exhibited typical syndromes of EAPDS. They put up weight with fat abdomen, gloomy hair, poor appetite, hypersomnia, lowered activities , reduced food intake, loose stool, dark red tongue, white tongue with white, thick, greasy fur. Lep could be taken as one of objective indicators for evaluating hypertension rat model with EAPDS.

OBJECTIVETo investigate the effect of four natures of medicine on therapeutic effect of acupoint sticking therapy.

METHODSSixty-one cases of primary dysmenorrhea were randomly divided into a capsaicin group (n=20), a menthol group (n=20) and a control group (n=21). They were treated respectively with capsaicin and menthol, which are extracts of Lajiao (Fructus Capsici) and Bohe (Herba Menthae) with same pungent in flavor and different cold (cool) and heat in property, and application of Tongjing Jiu Tieji (plaster for dysmenorrhea) at Shenque (CV 8). Changes of clinical symptoms before and after treatment were observed.

RESULTSAfter treatment, the cumulative scores of symptoms and the scores of pain decreased significantly in the 3 groups (P < 0.01), with no significant differences among the 3 groups (P > 0.05).

CONCLUSIONIn acupoint sticking therapy, the four natures of medicine have no obvious effect on the therapeutic effect, so the four natures of medicine should not used as main standard of medicine selection.

Objective To investigate the clinical significance of serum cytokines concentrations and A- PACHE scores in evaluating the illness state for critical trauma patients.Methods A clinical prospective self-control trial was performed,in which 36 patients admitted to ICU by SIRS were enrolled.Objects were divided into mild and severe trauma group according to APACHE score.The TNF-?and IL-6 concentrations were determined on the 1st, 3rd and 5th day of admission,the APACHE score were assessed at the same time.Statistic analysis was performed according to this group.Results The TNF-?concentrations decreased continuously in the following days while IL-6 decreased from the 7th day in the mild trauma group.In the severe trauma group the TNF-?and IL-6,APACHE score concentrations kept increasing.There was a significant difference of TNF-?and IL-6 concentrations between severe trauma and mild trauma group.Conclusion Dynamic measurement of TNF-?and IL-6 concentrations with APACHE score provide great help to evaluate the illness state and predict the prognosis.

Gene chip technology was employed to study gene expression in Tamarix androssowii under NaHCO3 stress. cDNAs from T. androssowii treated with NaHCO3 solution and that from control group were labeled with fluorescent dye CyS and Cy3 respectively. The two fluorescent cDNA probes were mixed and hybridized to gene chips containing T. androssowii genes, and the chips were scanned using biochip scanning system. Differential expression of genes was analyzed through calculation of the ratio of Cy5 to Cy3 signal intensities. Total of 89 genes differentially expressed were identified, among them, 27 showed down regulated expression and 62 showed up regulated expression. Blastx analysis showed that the function of the differentially expressed genes could be grouped into some categorizations such as photosynthesis, reactive oxygen species eliminated, regulation of osmotic potential, regulation of gene expression and signal transduction, metabolism, development, ribosomal protein, protein breakdown and recycling, transporter, water channel proteins and so on. Based on this research, some function-unknown or novel unreported genes that respond to salt stress were also identified, and these genes may have important functions in salt resistance of T. androssowii. Some important pathways of salt resistance in T. androssowii are revealed, and the gene expression profiling of T. androssowii under salt stress and without stress is obtained in this study.

Objective To develop a new isotope dilution gas chromatography mass spectrometry method (ID/GC/MS) for the measurement of serum cholesterol.Methods Serum was mixed with an isotope labeled internal standard ([3,4-~(13)C]-cholesterol) and treated with alcoholic sodium hydroxide to hydrolyze cholesterol ester to cholesterol.Cholesterol and internal standard was extracted and derived by N, O-Bis(trimethylsilyl) trifluoroacetamide to trimethylsilyl ethers.The derivation products were analyzed by capillary column GC combined with electron impact MS using scan and selected ion monitor (SIM) modes. Signals of cholesterol internal standard were corrected for the contributions from cholesterol and the signal ratio of cholesterol to internal standard for the calibrators were linearly regressed against cholesterol concentrations.The resulted regression equation was used for the calculation of serum cholesterol concentrations.Results The new ID/GC/MS method showed a mean within-run coefficient variance (CV) of 0.04%-0.81%.Comparison with two levels of standard reference material (SRM1951a) of National Institute of Standards and Technology (NIST) displayed a bias of 0.19% and 0.90% respectively.Conclusion A time-gaining ID/MS method has been established that is highly precise and accurate and can be used for the measurement of serum cholesterol.
