Measuring the content of soluble reducing sugar, total sugar, soluble protein, guanosine, alkaloids, and succinic acid of Pinellia ternata tuber were measured by anthrone-sulfuric acid colorimetric method, Coomassie brilliant blue method, RP-HPLC, reverse potentiometric titration, acid dye colorimetry, respectively. The result showed that yellow light could promote the growth and development of P. ternata and increase the content of soluble reducing sugar, total sugar, alkaloids, and succinic acid. Under blue light could promote the content of soluble protein and guanosine. Red and yellow light increased the content of chlorophyll a and chlorophyll b, contrastively blue light reduced the content of chlorophyll a and chlorophyll b. White film through the most uniform spectrum was most conducive to the synthesis of chlorophyll a. As single film, blue film, yellow film were more conducive to the synthesis of chlorophyll a, green film and red film had been relatively beneficial to the synthesis of chlorophyll b. Bulbil formed the largest number and the biggest propagation coefficient of P. ternata under red light showed that it could increase the production of P. ternata under red light.

OBJECTIVETo observe the effect of Ganoderma lucidum decoction in treating Russula subnigricans poisoning (RSP) patients.

METHODSThe 14 patients of RSP in the treated group were treated with GLD (GLD, one dose was prepared by 100 g of Ganoderma lucidum decocted with water to 600 ml), on the base of conventional treatment, and 11 patients received conventional therapy in the previous year were taken as control. The clinical efficacy and parameters in them were compared, including the urine N-acetyl-D-glucosaminidase (NAG, which reflects the injury of kidney), the red blood cell and protein in urine, the alanine transaminase (ALT, which reflects the injury of liver), and the aspartate aminotransferase (AST, which reflects the injury of heart).

RESULTSA better clinical cure-markedly improving rate was showed in the treated group as compared with the control group, P < 0.01. In the treated group, red blood cell in urine disappeared after 24 hrs treatment in the majority of patients, urinary protein reduced obviously and the other three parameters reached the peak at the 3rd day then lowered gradually. In the control group, all the parameters increased continuously. Comparison between the parameters at corresponding time in the two groups showed significant difference (P < 0.01), those in the treated group were markedly lower than those in the control group respectively.

CONCLUSIONGLD has good effect in treating RSP, could obviously lower the fatat rate of RSP.

AIM: Anti-atherosclerosis effects of Momordica charantia L was further studied in a New Zealand rabbit atherosclerotic model at the basis of anti-inflammation and antioxidant effects. METHODS: Animals were divided into 3 groups: normal group (normal rabbit diet), atherosclerosis group(diet containing 2% cholesterol), and Momordica charantia L group(diet containing 2% cholesterol and 1 5% sarcocarp of Momordica charantia L ). Ninety days later, all animals were sacrificed. The effect of Momordica charantia L on atherosclerosis was evaluated by measuring serum lipid and total cholesterol content of artery wall, observing fatty liver degree, aorta arteriosclerotic area, and the thickness of intima. RESULTS: The level of total serum cholesterol and LDL-C in Momordica charantia L treatment group were obviously lower than those in atherosclerosis group, so were the total cholesterol content of artery wall, fatty liver degree, atherosclerotic area, intima thickness and I/M ratio, but no significantly difference was found between the two groups in TG level. The level of HDL-C in Momordica charantia L treatment group was evidently lower than that in normal control group. CONCLUSION: Momordica charantia L has an anti-atherosclerosis action in rabbits.

OBJECTIVETo measure and analyze the personal noise exposure of city metro station workers by using noise dosimeter.

METHODSAccording to job category and work type, all workers were divided into 4 groups. The workers from each group were selected as subjects for personal noise exposure measurement. CEL-320 dosimeters were worn by each subject and noise data collected by a phone fixed at collar. All subjects were asked to take notes about their working activities when they were wearing CEL-320 dosimeters. Each worker's one workday LAeq, geometric mean and range of each group were computed.

RESULTSThere were many noise sources in the metro station, and the noise exposure was unstable. The varieties of personal noise levels were recorded among 48 workers, the highest LAeq work type was of the instrument room, (81.8 +/- 2.5) dB (A), and the biggest LAeq rang was of the hall, 8.1 dB (A). The lowest LAeq was of the station control room (68.7 +/- 1.8) dB (A) and the lowest LAeq rang also was there, 4.0 dB (A).

CONCLUSIONThe personal noise exposure of metro station should be implicated. Measuring personal noise exposure individually with dosimeters might obtain the noise exposure level more integrally in the complicated environment.

Objective To evaluate the efficacy of extended-field intensity-modulated radiotherapy (IMRT) in the treatment of patients with early-stage NK/T cell lymphoma (NKTCL),and to examine the clinical characteristics and the effect of treatment factors on the prognosis of these patients.Methods The clinical data of 165 patients with early-stage NKTCL who underwent extended-field IMRT with (n=158,95.8%) or without chemotherapy (n=7,4.2%) were reviewed.Of these 165 patients,140(84.8%) received a radiation dose of ≥50 Gy to the primary lesion,and 25 patients (15.2%) received a radiation dose of<50 Gy.Most patients (n=147,89.1%) were treated with L-asparaginase-based chemotherapy regimens,whereas only 11 patients (6.7%) were treated with doxorubicin-based CHOP/CHOP-like regimens.In addition,109 patients (66.1%) received ≥4 cycles of chemotherapy.Locoregional control (LRC),overall survival (OS),and progression-free survival (PFS) rates were calculated using the Kaplan-Meier method,and the log-rank test was used for survival comparison and univariate prognostic analysis.A multivariate prognostic analysis was performed using the Cox model.Results The 5-year sample size 55.The 5-year OS,PFS,and LRC rates of all patients were 74.2%,72.5%,84.4%,respectively.The patients who received a dose of ≥50 Gy had a significantly higher 5-year LRC rate than those with<50 Gy (91.8% vs.39.7%,P=0.000).The 5-year OS was significantly higher in the low-risk early-stage group than in the high-risk early-stage group (P=0.002).For the high-risk early-stage NKTCL group,patients who received ≥4 cycles of chemotherapy had significantly higher 5-year OS and PFS than those who received<4 cycles of chemotherapy (5-year OS:71.3% vs.59.5%,P=0.032;5-year PFS:70.4% vs.54.4%,P=0.009).In addition,multivariate analysis showed that ECOG≥2,primary tumor invasion (PTI),and Ann Arbor stage Ⅱ were associated with poor OS (P=0.006,0.002,0.014),and ECOG≥2 and PTI were associated with reduced LRC (P=0.004,0.016).Furthermore,ECOG≥2,PTI,Ann Arbor stage Ⅱ,and extranasal primary site were associated with lower PFS (P=0.045,0.003,0.030,0.032).Conclusions Extended-field IMRT at a dose of ≥50 Gy can lead to favorable LRC,OS,and PFS in patients with early-stage NKTCL.However,it is less effective against distant early-stage NKTCL in patients with poor prognosis.Nevertheless,≥4 cycles of chemotherapy can significantly improve the OS and PFS of patients with early-stage NKTCL.

BACKGROUND: Blood hemoperfusion with resin adsorption can clean larger molecules that exceed the molecular weight cutoff of combined continuous veno-venous hemofiltration (CVVH). Hence blood hemoperfusion with resin adsorption combined CVVH (HP+CVVH) has higher ability of mediator clearance, and can improve clinical outcomes in theory. This study aimed to investigate the effect of blood hemoperfusion with resin adsorption combined continuous veno-venous hemofiltration (HP+CVVH) on plasm cytokines like TNF-α, IL-1β, IL-6, cellular immunity and prognosis in patients with multiple organ dysfunction syndrome (MODS). METHODS: This was a prospective, randomized clinical trial. A total of 30 patients who had been diagnosed with MODS were enrolled in this study. Patients were randomly allocated to routine treatment+HP+CVVH group (treatment group) and routine treatment+only CVVH group (control group). In the treatment group, patients received blood hemoperfusion with resin adsorption for 2 hours, and then received CVVH for 10 hours every day. In the control group, patients received CVVH for 12 hours only every day. The patients in the two groups received blood purification therapy for three days. The plasma of patients in the treatment group was obtained at 0, 2, 12, 24, 26, 36, 48, 50, 60 hours, 5th day, 7th day and 10th day, respectively. The plasma of patients in the control group was obtained at 0, 12, 24, 36, 48, 60 hours, 5th day, 7th day and 10th day, respectively. APACHE II score, T-lymphocytes subpopulations, blood lactate acid concentration, heart rate, breathing rate, and oxygenation index were observed. RESULTS: Plasma cytokines like TNF-α, IL-1β, IL-6 decreased markedly after HP (P<0.01);T-lymphocytes subpopulations CD3+, CD4+, CD8+, CD4+/CD8+ increased after HP+CVVH or only CVVH. The plasma concentrations of TNF-α, IL-1β and IL-6 in the two groups were not markedly different at 12, 36, and 50 hours. But on the 5th day, the plasma concentrations of TNF-α, IL-1β and IL-6 in the treatment group were lower than those in the control group (P<0.05). On the 28th day, 5 patients died in the treatment group, and 6 patients in the control group. CONCLUSIONS: Both HP+CVVH and CVVH can clean plasma cytokines like TNF-α, IL-1β, and IL-6, and improve cellular immunity and clinical symptoms and signs of patients. Compared with only CVVH, the plasma concentrations of TNF-α, IL-1β and IL-6 were lower on the 5th day, and patients have an increased survival rate on the 28 day in the HP+CVVH group.

AIM: To study the effects of apolipoprotein (apo) A-Ⅰon ATP binding cassette transporter A1 (ABCA1) degradation and cholesterol efflux in THP-1 macrophage-derived foam cells. METHODS: After exposure of the cultured THP-1 macrophage-derived foam cells to apolipoprotein A-Ⅰ for different time, cholesterol efflux, ABCA1 mRNA and protein level were determined by liquid scintillation counting, reverse transcriptase-polymerase chain reaction and Western blotting, respectively. The mean ABCA1 fluorescence intensity on THP-1 macrophage-derived foam cells was detected by flow cytometry. RESULTS: ApoA-Ⅰ markedly increased ABCA1-mediated cholesterol efflux from THP-1 macrophage-derived foam cells. This was accompanied by an increase in the content of ABCA1. ApoA-Ⅰ did not alter ABCA1 mRNA abundance. Thiol protease inhibitors increased the level of ABCA1 protein and slowed its decay in THP-1 macrophage-derived foam cells, whereas none of the proteosome-specific inhibitor lactacystin, other protease inhibitors, or the lysosomal inhibitor NH_4Cl showed such effects. The apoA-Ⅰ mediated cellular cholesterol efflux was enhanced by thiol protease inhibitors. CONCLUSION: Thiol protease inhibitors might provide an alternative way to upregulate ABCA1 protein. This strategy is especially appealing since it may mimic the stabilizing effect of the natural ligands apoA-Ⅰ.

OBJECTIVE: To explore the applicability of integration between three-dimensional (3D) facial and dental data to evaluate the nasolabial morphology variation before and after the cross-arch fixed restoration of the maxillary implant-supported prostheses. METHODS: Twelve patients (4 women and 8 men), mean age (54.82±5.50) years (from 45 to 62 years) referred to the Department of Oral Implan-tology, Peking University School and Hospital of Stomatology, were selected and diagnosed with edentulous maxilla. For all the patients, 4 to 6 implants were inserted into the maxilla. Six months later, the final cross-arch fixed prostheses were delivered. The 3D facial images were collected before and after the final restoration. The 3D data of prostheses were also captured. All the 3D data were registered and measured in the same coordinate system. Then the displacement of all the landmarks [cheilion left (CHL), cheilion right (CHR), crista philtri left (CPHL), crista philtri right (CPHR), labrale supe-rius (LS), subnasale (SN), stomion (STO), upper incisor (UI), upper flange border of the prostheses (F-point, F)], and the variation of the distances between these landmarks (SN-LS, CPHR-CPHL, CHR-CHL, LS-STO) were analyzed and compared. RESULTS: The consistency test among three measurements of the length of F-SN indicated that the integration method of the dental prostheses and soft tissue had the good repetitiveness, ICC=0.983 (95%CI: 0.957-0.995). After wearing the final cross-arch maxillary implant-supported prostheses, all the landmarks on the soft tissue moved forward. The nasal base area changed minimally, and the shift of SN in the sagittal direction was only (0.61±0.44) mm. But the sagittal shift of LS was (3.12±1.38) mm. In the vertical direction, SN, LS, CPHL, and CPHR moved upward. But STO, CHL, and CHR moved downward a little. Except for the slight decrease of the length of philtrum (SN-LS), the length of CHL-CHR, CPHL-CPHR, and the height of upper lip were increased together (P < 0.01). In the direction of Z axis, the strong correlations were found not only between the movements of SN and F (r=0.904 3) but also between the movements of LS and UI (r=0.958 4). CONCLUSION The integration method of 3D facial and dental data showed good repetitiveness. And the strong correlations between the landmarks of prostheses and nasolabial soft tissue in the sagittal direction were found by this new method.

Objective: Conventional open spinal surgery of adult scoliosis can be performed from anterior, posterior, or combined approach. Minimally invasive spine surgery (MISS) was developed for the purpose of reducing the undesirable effects and complications. This review aimed to make a brief summary of recent studies of the approach and clinical outcomes of MISS in adult scoliosis. Data Sources: We conducted a systematic search from PubMed, Medline, EMBASE, and other literature databases to collect reports of surgical methods and clinical outcomes of MISS in treatment of adult scoliosis. Those reports were published up to March 2017 with the following key terms: "minimally invasive," "spine," "surgery," and "scoliosis."Study Selection: The inclusion criteria of the articles were as followings: diagnosed with adult degenerative scoliosis (DS) or adult idiopathic scoliosis; underwent MISS or open surgery; with follow?up data. The articles involving patients with congenital scoliosis or unknown type were excluded and those without any follow?up data were also excluded from the study. The initial search yielded 233 articles. After title and abstract extraction, 29 English articles were selected for full?text review. Of those, 20 studies with 831 patients diagnosed with adult DS or adult idiopathic scoliosis were reviewed. Seventeen were retrospective studies, and three were prospective studies. Results: The surgical technique reported in these articles was direct or extreme lateral interbody fusion, axial lumbar interbody fusion, and transforaminal lumbar interbody fusion. Among the clinical outcomes of these studies, the operated levels was 3–7, operative time was 2.3–8.5 h. Both the Cobb angle of coronal major curve and evaluation of Oswestry Disability Index and Visual Analog Scale decreased after surgery. There were 323 complications reported in the 831 (38.9%) patients, including 150 (18.1%) motor or sensory deficits, and 111 (13.4%) implant?related complications. Conclusions: MISS can provide good radiological and self?evaluation improvement in treatment of adult scoliosis. More prospective studies will be needed before it is widely used.
