Simulated result treating oil-polluted wastewater in laboratory showed that after "XingyiLian" wastewater of Liaohe Oil Field was treated by fluidized-bed bioreactor system with the vehicle of activated carbon , the amount of oil and CODcr of the flow out water were decreased from 45mg/L to 4. 1mg/L and 470mg/L to 42mg/L separately , according with first class standards of Chinese Wastewater Discharge Regulation.

Based on reservoir condition and fluid characteristics, the oil-degrading bacterial strain NX-2 was screened from Ma-2 fault block of Huabei oil field. Bacterial metabolism and the capability of improving oil property were evaluated on oxygen-deficient condition. At 87℃ which reservoir temperature is, artificial homogeneous core displacement experiment indicated the enhanced oil recovery of microbe was 7.1% higher than that of waterflooding. In experiment on individual well Ma-410, additional oil production of 669 tons was gained, and decreased water production of this trial well reached more than 3000 tons. These results demonstrated NX-2 could adapt to stratum conditions, enhance oil recovery and improve oil property as well.

Objective To study the clinicopathologic features and explore the potential prognostic factors of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma).Methods 86 patients diagnosed with MALT lymphoma were retrieved and divided into 2 subgroups according to the location of tumor,namely gastric (32 cases) and non-gastric (54 cases) subgroup.Histological characteristics were reassessed on hematoxylin-eosin staining slides,and immunophenotypic features were determined by immunohistochemical staining.Interphase fluorescence in-situ hybridization (FISH) was carried out to detect the cytogenetic abnormalities.Results There were no significant difference of clinical behavior,histology,and immunophenotype between gastric and non-gastric subgroups.In addition,FISH detected t(14;18) in 9 ％ (4/45) and t(11;18) in 12 ％ cases (6/50) respectively.Among the 20 cases treated with H pylori (HP) eradication,a significantly lower remission rate was observed in cases with bcl-10 (20 ％) nuclear expression or those harboring t(11;18) (33 ％) compared with those in the negative group (73 ％,91％)(x2 =3.842 and 4.639,P =0.035 and 0.031,respectively).For the 35 non-gastric patients with follow-up data,males (35 ％) and patients older than 60 yrs (25 ％) tended to have a lower remission rate as compared to females (60 ％) and those younger than 60 yrs (63 ％) (x2 =3.905 and 7.373,P =0.048 and 0.007,respectively).Moreover,progression-free survival rate was significantly lower in patients with higher stage (ⅢⅣ) (25 ％) and without t(14;18) (50 ％) than that in patients with stage Ⅰ-Ⅱ (52 ％) and with t(14;18)(75 ％).The differences had statistical significance (x2 =4.207 and 4.363,P =0.040 and 0.037,respectively).Conclusion MALT lymphoma in general is an indolent B-cell non-Hodgkin’ s lymphoma which more frequently occurs in the elderly people.Differences in the response to treatment or the prognosis are observed between gastric and non-gastric MALT lymphoma patients.

Objective To observe the efficacy and acute inflammatory reactionof Qingjin Huazhuo Prescription combined with Western medicine therapy for treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods Totally 60 hospitalized patients with AECOPD (Grade Ⅱ) and acute exacerbation course≤1 week were enrolled in this study. The patients were randomly divided into two groups, with 30 cases in each group. The control group was treated with conventional Western medicine. The observation group was treated with conventional Western medicine and oral administration of Qingjin Huazhuo Prescription for 10 days, once a day. TCM syndrome and dyspnea grading (mMRC score), white blood cell (WBC), C-reactive protein (CRP), procalcitonin (PCT) and partial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PaCO2), were measured before and after the treatment. Results The total scores of TCM syndromes and cough, expectoration, wheezing, fever, and cyanosis in the two groups decreased significantly (P<0.05). The improving degrees of cough and expectoration were better in the observation group than in the control group (P<0.05). The scores of mMRC in the two groups were better than before treatment (P<0.05). The levels of WBC, CRP and PaCO2 in the two groups were lower than those before treatment (P<0.05). The decreased degrees of CRP and PaCO2 in the observation group were better than those in the control group (P<0.05, P<0.01). Conclusion Qingjin Huazhuo Prescription combined with Western medicine therapy can relieve clinical symptoms, reduce the acute inflammatory reaction of AECOPD patients and improve respiration.

Abstract: The loop-mediated isothermal amplification (LAMP) technique is a technique for the specific and efficient amplification of target fragments at a constant temperature using two pairs of specially designed primers and a strand displacement activity DNA polymerase. LAMP technique is a simple, rapid, specific, sensitive and cost-effective nucleic acid amplification method, and therefore has a promising future in the field rapid detection of Mycobacterium tuberculosis and grassroots applications. In this review, the basic principles and characteristics of the LAMP technique, the main molecular markers for the diagnosis of tuberculosis, and the use of different molecular markers and various types of novel techniques in the diagnosis of pulmonary tuberculosis, extrapulmonary tuberculosis, and drug-resistant tuberculosis were described. The LAMP technique has been widely used in the diagnosis of tuberculosis with high sensitivity and specificity, but the technique still has some shortcomings. This paper reviews the progress of its application in tuberculosis in recent years and provides an outlook on its development, with a view to providing a rational research direction for rapid diagnosis of tuberculosis in a resource-limited environment.

In the past few decades, our understanding of platelets has made great progress. Platelets play an unexpected central role in cancer and greatly affect the behavior of cancer cells. At the same time, the physiology and phenotype of platelets are also affected by cancer cells. Therefore, platelet-based tumor targeted therapy strategies have attracted the attention of researchers, but the limitations of their application require more attention. In this paper, the strategies of platelet-based tumor targeted therapy are summarized, and the strategies of platelet mimicking nanocarrier delivery, platelet hitch riding, platelet membrane coating biomimetic and engineered platelet targeting are mainly introduced. The easy activation, hard storage and unknown functional and phenotypic changes of platelets were discussed. At the same time, the strategy of platelet-based targeted tumor therapy is reviewed from theoretical basis and practical application. The development potential of platelets in the field of tumor diagnosis and treatment is discussed, which will provide some theoretical reference for the study of platelet-related tumor diagnosis and targeted therapy.

OBJECTIVETo study the effect of Jingjielianqiao Decoction in promoting leg ulcer in rabbits.

METHODSNine adult male New Zealand albino rabbits with chronic leg ulcers were randomized into 3 groups, namely group A treated with Jingjielianqiao Decoction, group B with Shengjiyuhong Decoction, and group C with normal saline. Gross observation of the wounds was carried out regularly for evaluating the changes in the ulcerous area, depth and wound surface excretion. After 3 weeks of treatment, the tissues on the edge of the ulcer were sampled and prepared for routine pathological examination, electron microscopy and immunohistochemistry for vascular endothelial growth factor (VEGF) and CD34. The number of blood vessels and their areas were also recorded.

RESULTSThe wounds showed no significant differences between the 3 groups by gross observation during the treatment, but after completion of the 3-week treatment, routine pathological examination and electron microscopy revealed significant differences between the groups. Immunohistochemistry for VEGF and CD34 yielded comparable results between groups A and B (positive control), but showed significant differences between group C and the other two groups (P<0.01).

CONCLUSIONJingjielianqiao Decoction and Shengjiyuhong Decoction can obviously promote the healing of leg ulcer in rabbits.

OBJECTIVETo compare the effects of greenlight photoselective vaporization prostatectomy (PVP) and thulium laser vaporesection of the prostate (TmLRP) in the treatment of aged high-risk BPH patients with the prostate weighing > 80 g.

METHODSWe included in this study 118 high-risk BPH patients aged 62-96 (mean 76) years with the prostate heavier than 80 g, 82 treated by PVP and the other 36 by TmLRP. Then we compared the operation time, intraoperative bleeding, complications, short-term effectiveness, and surgical cost between the two groups.

RESULTSAll the patients tided over the perioperative period without blood transfusion and serious complications. The mean operation time, postoperative bladder irrigation time and surgical cost were significantly less in the TmLRP than in the PVP group (P < 0.05). Both the procedures remarkably improved the international prostatic symptom score (IPSS), quality of life (QOL), post void residual urine (PVR) and Qmax of the patients (P < 0.05), but with no significant differences between the two groups (P > 0.05).

CONCLUSIONBoth PVP and TmLRP are effective and safe for the treatment of aged high-risk BPH patients with the prostate heavier than 80 g, but the latter is superior for its shorter operation time and lower surgical cost.
