OBJECTIVE To investigate the transcription level of gene hld of Staphylococcus epidermidis in the biofilm forming and detaching under MIC antibiotic and explore the relationship between biofilm-related drug resistance and persistant infection.METHODS The transcription level of gene hld of S.epidermidis under MIC concentration of 4 antibiotics was compared with those of the control group without antibiotics by SYBR real-time fluorescent quantitative RT-PCR at the different time point of biofilm formation and detachment.RESULTS The transcription of gene hld decreased rapidly from initial adherence,and droped continuously for few hours.There was an increase from 24 hours to 72 hours in groups without antibiotics but not in antibiotics groups,the differenet was significant.CONCLUSIONS Antibiotics improve adherence at first and then prevent matrix decomposition water-conducting tube and detachment of cells by impact of transcription of gene hld,it can protect cells from killing by inhibiting the penetration of biotics and prevent them become planktonic cells after detachment from biofilm.

Background and purpose: Ovarian lymphoma (OL) is usually misdiagnosed as ovarian cancer with bulk lymph node invasion (OC-BLN), and vice versa. Therefore, to distinguish these two types of disease, we compared their clinical characteristics in this study. Methods: This study retrospectively reviewed 14 OL and 14 OC-BLN patients from Fudan University Shanghai Cancer Center and Shanghai Eighth People's Hospital. The clinical char-acteristics, image and laboratory examination data were compared. Results: There was no significant difference in age, symptom, fever, weight loss and volume of ascitic fluid between the two groups. Comparing with OC-BLN, OL patients have larger tumor in ovaries [(13.04±5.94) cm vs (7.78±6.38) cm, P=0.033], and higher percentage of solid ovarian tumor (85.71% vs 28.5%, P=0.006). Lactate dehydrogenase(LDH)/CA125 was higher in OL (7.66±8.03) than OC-BLN (0.31±0.27, P=0.009). Using LDH/CA125 to diagnose OL, area under the curve (AUC) was 0.952. When the threshold value was set at 1, the sensitivity and specificity was 91.7% and 100%, respectively. Conclusion: OL and OC-BLN are easily to be misdiagnosed. OL has larger and more solid tumor than OC-BLN. LDH/CA125 can help to distinguish these two diseases and guide clinical decision making.

Objective To investigate the efficacy and safety of ultra-mini percutaneous nephrolithotomy for the treatment of renal or upper ureteral stones.Methods The data of 32 patients diagnosed as renal or upper ureteral stones were retrospectively reviewed,who underwent ultra-mini percutaneous nephrolithotomy from June to October,2015,including 29 kidney stones,3 upper ureteral stones,of which 21 single stone,7 multiple stones,and 4 staghorn stones.There were 8 cases with inferior calyx stones,10 with renal pelvis stones,3 with upper ureteral stones,10 with renal pelvis stones plus inferior calyx stones and 1 with renal pelvis stones plus upper calyx stones.The mean stone size was (20.1 ±7.6) mm (ranging from 10 to 41mm).The mean Hounsfield unit (HU) was (1 125.9 ±225.9) Hu (ranging from 520 to 1 550Hu).In this cohort,13 cases had mild hydronephrosis,2 moderate hydronephrosis,1 severe hydronephrosis while no hydronephrosis identified in the other 16 patients.One case had concomitant kidney and ureter duplication malformation,and 1 case had residual stones after laparoscopic nephrolithotomy.Results All of the patients were treated by single tract UMP.Among them,middle calyceal puncture was performed in 9 cases,and the other 23 cases underwent lower calyceal puncture,including 4 cases of intercostal puncture,and 28 subcostal puncture.The mean operating time was (30.3 ± 15.0) min (ranging from 10 to 90 min).The mean postoperative hospital stay was (1.9 ± 1.0)days (ranging from 1 to 5 days).The mean hemoglobin decrease was(14.6 ±8.4)g/L (ranging from 1 to 46 g/L).No analgesics were used.Peri-operative complication rate was 3.13％ (1/32) with 1 case of collection system perforation.There was no fever,severe bleeding,urinary extravasation,pleural injury,or blood transfusion.The SFR was 93.75％ (30/32) and 96.88％ (31/32) on the first day and the first month after the operation,respectively.Conclusions UMP could be a safe and effective method for the treatment of renal or upper ureteral stones,especially for inferior calyceal stones less than 2cm.It offers high stone clearance rate,minimally invasiveness,quick recovery,short length of hospital stay and improved quality of life.

Objective To outline the research fronts of ten major sub-specialties in internal medicine.Methods Based on their impact factor scores and the proportion of the journals of 10 subspecialties (endocrinology & metabolism,cardiac & cardiovascular systems,hematology,infectious diseases,nephrology,gastroenterology & hepatology,respiratory system,rheumatology,critical care medicine,clinical neurology) in Journal Citation Report (JCR),and careful consulation of expert clinicians,we identified 50 journals.Their bibliographic records (including references) published in 2011 were downloaded,and the frequency of the references (citations) in each sub-specialty was counted and the highly cited records were extracted.We performed a clustering analysis according to the co-cited times among any pairs of the highly cited records.To tag each cluster of highly cited records,we browsed the titles and abstracts of all highly cited records in the same cluster,and concluded the main topics of each cluster.Finally,we extracted the current published papers devoted to particular cluster by some clustering analysis indicators.The clusters of highly cited records were considered as the intelligence base,and the main topics in current papers which citing these highly cited papers were considered as research fronts.Results Totally 50 journals on 10 sub-specialties in internal medicine were identified.A total of 202 highly cited papers,38 clusters (knowledge bases),and 152 corresponding current citing papers presenting the research fronts were selected.Conclusions We confirm and present research fronts in 10 major sub-specialties of internal medicine.This study provides a synchronic structure of contemporary research activities in internal medicine sub-specialties.

The parthenogenetic embryonic stem cells (pESCs) derived from parthenogenetic embryos have the totipotency and proliferation capacity similar to those of the fertilized embryonic stem cells (fESCs). Therefore, the establishment of pESCs line avoids destroy of embryo and kence may make pESCs less concerns with political and ethical issues. These cells are characterized by their histocompatibility with the oocyte donor and therefore is more suitable for cell and tissue replacement therapy. In addition, because of the typical imprinting status, pESCs also provide a valuable in vitro model system for studying the molecular mechanisms in genomic imprinting.

To construct a scFv library by phage display technique from the spleen cells of mice immunized with B3HM cells. Three mice were immunized with B3HM cells, and their spleen cells were harvested. The genes of VH and Vk were amplified by RT-PCR from the cDNA of the immunized spleen cells and a scFv-phage display antibody library was constructed. The capacity of library was measured,and the variety of the library was analyzed by digesting with restriction endonuclease BstNI.ScFv phage clones were randomly picked and identified phage-scFv clone by binding B3HM cells using immunofluorescein.A scFv library containing 5?106 individual clones which showed different patterns after digested with restriction endonuclease BstNI was produced. Individnal phage-scFv clone showed B3HM cells positive using immunofluorescein. A scFv library of anti-B3HM cell surface molecules has been constructed. It will be useful for finding out some novel genes of causing leukemia, and establishs the infarctate foundation of clarifying the pathogenesis of leukemiagenesis.

The occurrence of foreign body is uncommon in youths and adults. We report here a case of 16-year-old boy who inhaled a foreign body which was overlooked for 6 months. The patient suffered productive cough and received antibiotic treatment for 10 days. But the symptoms did not improve. Chest radiography and CT scan revealed a 1-cm-long needle-like foreign object in the right inferior lobar bronchus. Wedge resection of lung was finally performed because of severe hemorrhage caused by prior bronchoscopy.

OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.

METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.

RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.

CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.
