Family physicians may be called upon to respond to trauma patients in their clinics or at scene of injury. Managing trauma can be daunting to any physician who encounters it infrequently. The physician first responder needs to shut out the chaos and distractions at scene and focus on a systematic primary survey to assess for injuries with the potential to cause rapid deterioration, institute crucial life-saving interventions and effect rapid evacuation to hospital. This article details a simple approach to guide the family physician to assess and prioritise management of the trauma patient, and augment the work of the paramedics in the pre-hospital phase.

Through scale-up cultivation of Eriobotrya japonica suspension cells using WAVE bioreactor, the cell growth and ursolic acid (UA) accumulation were studied. The comparison test was carried out in the flask and the reactor with cell dry weight (DW) and UA content as evaluation indexes. The culture medium, DW and UA content were compared in 1 L and 5 L working volumes of bioreactor. The orthogonal test with main actors of inoculation amount, speed and angle of rotation was developed to find the optimal combination, in 1 L working volume of bioreactor. DW of the cell growth and the UA content in bioreactor were higher than those of the shaker by 105.5% and 27.65% respectively. In bioreactor, the dynamic changes of elements in the fluid culture, the dry weight of the cell growth and the UA content in 1 L and 5 L working volumes were similar. Inoculation of 80 g, rotational speed of 26 r · min(-1), and angle of 6 ° was the optimal combination, and the cell biomass of 19.01 g · L(-1) and the UA content of 27.750 mg · g(-1) were achieved after 100 h cultivation in 1 L working volume of bioreactor. WAVE Bioreactor is more suitable than flasks for the E. japonica cell suspension culture, and culture parameters can be achieved from 1 L to 5 L amplification.

OBJECTIVETo study the effects of Jisuikang (Chinese characters) on Nogo-NgR gene expression, and to explore the protective effects and mechanism of Jisuikang (Chinese characters) on spinal cord injury in rats.

METHODSOne hundred eighty female rats were randomly assigned to 6 groups(30 rats per group). Sham group: T10 lamina was resected only and spinal cord was untreated. Model group: spine cord injury (SCI) was created with a modified impinger of Allen's by impacting on the T10 spinal cord. Prednisolone group: Prednisolone (0.06 g/kg) was given by intragastric administration at a time interval of 24 hours after operation. The Jisuikang (Chinese characters) high, moderate and low dose groups: Jisuikang (Chinese characters) was supplied with different dose (50 g/kg, 25 g/kg, 12.5 g/kg) by intragastric administration in rats after operation,for the first time at 30 min after surgery. Animals were killed 3, 7, 14 days after surgery. The expression levels of Nogo-A and NgR were observed by Western Blot and Real-time PCR.

RESULTSThe expression of Nogo-A and NgR was at the basic level at all time points in sham group. Compared with model group, the protein expression levels of Nogo-A and NgR in sham, prednisolone, Jisuikang (Chinese characters) moderate dose groups were statistically significant at all time points (P < 0.05). No difference was found in Jisuikang (Chinese characters) high and low dose groups (P > 0.05). Three days after surgery, the mRNA levels of Nogo-A and NgR in treatment group were significantly lower than that in model group (P < 0.01); 7 days after surgery,Nogo-A and NgR mRNA expression were dramatically upregulated and peaked; 14 days after operation, the expression was decreased, but still significantly higher than that in other treatment groups (P < 0.01). Prednisolone and Jisuikang (Chinese characters) moderate dose groups showed the most significant effects among all groups,but there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONThe decoction Jisuikang (Chinese characters) can promote the nerve cell regeneration by regulating Nogo-A and NgR gene expression, activating Nogo- NgR signaling pathways after acute spinal cord injury.

Retinoid resistance has limited clinical activity of retinoids as differentiation-inducing and apoptosis-inducing drugs. The present study was designed to investigate whether celecoxib (selective COX-2 inhibitor) has effects on cellular retinoid sensitivity of human colon cancer cell lines and its possible mechanism. Cell viability was measured by MTT assay. Apoptosis was detected by Annexin-V/PI staining and flow cytometry assay. PGE2 production was measured by ELISA assay. Expression of RARbeta was assayed by Western blotting. The results showed that celecoxib enhanced the inhibitory effect of ATRA in both COX-2 high-expressing HT-29 and COX-2 low-expressing SW480 cell lines. Further study showed the ATRA and celecoxib combination induced greater apoptosis, and the addition of PGE2 did not affect the number of apoptotic cells induced by the combination. Moreover, NS398 (another selective COX-2 inhibitor) did not affect the inhibitory effects of ATRA on both cell lines. Western blotting showed that the expression of RARbeta in HT-29 cell lines increased in celecoxib group and combination group. And the addition of PGE2 did not affect the expression of RARbeta induced by celecoxib either. In conclusion, celecoxib increased expression of RARbeta and cellular ATRA sensitivity through COX-2-independent mechanisms, which may provide a potential strategy for combination therapy.

BACKGROUNDDiagnostic hysteroscopy and directed biopsy has been widely used to evaluate abnormal uterine bleeding. We aimed to explore the value of hysteroscopy and directed biopsy in the diagnosis of endometrial carcinoma.

METHODSTwo hundred and eighty-seven patients with endometrial carcinoma who were treated in Beijing University People's Hospital, Beijing, China were distributed into 2 groups: Group A (90 patients) was examined using hysteroscopy and directed biopsy, and Group B (197 patients) was examined using fractional dilatation and curettage (D&C). The diagnostic veracity of the two methods, the rate of positive peritoneal cytology and the prognosis of the 2 groups were compared.

RESULTSIn Group A, 97.8% (88/90) of patients were diagnosed pathologically before surgery; the rate was 88.8% (175/197) for Group B. The difference between the 2 groups was statistically significant (P < 0.05). The sensitivity, specificity, positive predictive value and negative predictive value for the two methods for detecting cervical involvement were 77.8%, 100%, 100% and 97.6% for Group A and 65.3%, 92.6%, 74.4% and 90.0% for Group B, respectively. The positive peritoneal cytology rate was 5.6% (5/90) in Group A and 6.09% (12/197) in Group B. The difference was not statistically significant (P > 0.05). The 3-year and 5-year overall survival rates were 91.4% (33/36) and 82.4% (14/17) for Group A and 95.6% (87/91) and 86.7% (39/45) for Group B. There were no statistically significant differences between the two groups' survival rates (P > 0.05).

CONCLUSIONCompared with fractional D&C, hysteroscopy and directed biopsy offered improved pathological diagnostic accuracy before surgery and discovered cervical involvement more precisely in endometrial carcinoma patients, but it did not increase the positive peritoneal cytology rate or affect the prognosis of these patients.
