OBJECTIVETo observe the efficacy and side effects of the combination therapy of oxaliplatin and S-1 in treating postoperative colorectal cancer patients.

METHODS54 postoperative colorectal cancer patients received the combination therapy of oxaliplatin and S-1 regimen, repeated every 3 weeks, and evaluate the efficacy after 3 cycles.

RESULTSAll of the 54 patients but 2 (changed the chemotherapy regimen after the first cycle because of economic reason) finished 6 cycles of the chemotherapy treatment. There were 6 cases (11.5%) with complete response (CR), 28 cases (53.8%) with partial response (PR), and the overall response rate was 65.4%. Major adverse effects were hematological toxicities, gastrointestinal disturbance, neurosensory toxicity. There were no chemotherapy-related deaths.

CONCLUSIONSOxaliplatin combined with S-1 is an effective and better tolerated chemotherapy treatment for postoperative colorectal cancer patients, with no serious side effects for liver and kidney. Therefore, it can be used as an alternative chemotherapy regimen for postoperative colorectal cancer patients.

OBJECTIVETo study the clinical characteristics and the treatment of periorbital injuries.

METHODS61 cases were treated, including 30 cases orbitozygomatic fracture, 6 cases of frontal-orbital fracture, 8 cases of naso-ethmoid-orbital fracture, 7 cases of blow -out fracture and 10 cases of complicated fracture. The patients were diagnosed after physical examination and other examination, like CT. Through bicoronal or local mini incision at the end of eyebrow, combined with subciliary incision and local wound approach, the fractured sites were exposed completely. Then the fractured fragments were repositioned and fixed rigidly. The orbital wall was reconstructed with titanium net and Medpor.

RESULTSThe wounds healed primarily. Good cosmetic and functional results achieved in most of the patients. 4 cases underwent second-stage ophthalmectomy. 2 patients had diplopia after operation, but improved gradually. 3 cases of blepharoptosis needed further treatment.

CONCLUSIONSEarly diagnosis and treatment is very important for periorbital injuries. Fracture reposition and orbital wall reconstruction should he performed at early period.

We aimed to study the effect of allitridum (All) on the transient outward potassium current (Ito) of ventricular myocytes of spontaneously hypertensive rats (SHR). Totally 30 male SHRs were randomly divided into three groups: low-dose All group (7.5 mg·kg(-1)), high-dose All group (15.0 mg·kg(-1)) and normal saline group. The other 10 sex and age matched Wistar-kyoto rats (WKY) were also taken as control group (WKY group). All animals received i.p. administration for 8 weeks. The dual enzymatic method was used to separate single ventricular myocyte from animals. Patch-clamp technique was used to record Ito and analyze the effect of All on the current. It was shown that the left ventricular hypertrophy of SHR was reversed significantly by All. Furthermore, the density of Ito was recovered in both high and low dose All groups. The peak current densities of Ito were enhanced from 18.23±3.64 to 25.17±2.86 pA/pF (P<0.01) and 36.47±5.42 pA/pF (P<0.01) at +50 mV by All 7.5 mg·kg(-1) and 15.0 mg·kg(-1), respectively, which was not significantly different with WKY group. The effect was associated with positive shift of the steady-state, close-state inactivation, and shortened recovery from inactivation of Ito. It is concluded that All decreases the remodeling of Ito of ventricular hypertrophic myocytes of SHR.

OBJECTIVETo explore the effect of the mixed liquor of danshen and magnesium sulfate injection on inflammatory reaction caused by autoimmune response of rabbits with lumbar intervertebral disc herniation.

METHODSSixty rabbits were divided into blank group (10 rabbits), sham operation group (10 rabbits), model group (40 rabbits) according to method of random digits table. Then model group was divided into made group (group A, 10 rabbits), normal saline group (group B, 10 rabbits), aescin natrium group (group C, 10 rabbits) and danshen and magnesium sulfate injection group (group D,10 rabbits). After model success of lumbar intervertebral disc herniation, different drugs were given to rabbits with lumbar intervertebral disc herniation by ear margin vein. The rabbits of the group C,B,D were respectively given aescin natriu (0.5 mg/kg), normal saline (5 ml/kg), danshen and magnesium sulfate injection (2.0 mg/kg). The rabbits of blank group, sham operation group and group A were not given any disposal. The IgG and IgM level in serum of different groups were determined with ELISA method in fourteen day after model success and drugs given.

RESULTSThe level of IgG and IgM in the group A was higher than that of blank group and sham operation group (P < 0.05). The level of IgG and IgM in the group D was lower than that of group B,C (P < 0.05).

CONCLUSIONThe mixed liquor of danshen () and magnesium sulfate injection could inhibit inflammatory reaction caused by autoimmune response of lumbar intervertebral disc herniation,which provides a new alternative for lumbar intervertebral disc herniation.

Nasal intermittent positive pressure ventilation (NIPPV) can augment nasal continuous positive airway pressure (nCPAP) by delivering intermittent positive pressure ventilation in a noninvasive way and can provide a new option for neonatal noninvasive respiratory support. NIPPV has an advantage over nCPAP in primary and post-extubation respiratory support. Moreover, it can reduce severe apnea of prematurity. Synchronized NIPPV has promising application prospects. This review article summarizes the advances in the application of NIPPV in neonatal respiratory support to promote the understanding and standardization of this technique.

OBJECTIVETo study the influence of manufacture technique on the translucency and color of dental porcelain.

METHODSSpecimens were made of VITA VMK 95 dentin porcelain and enamel porcelain and divided into 3 groups: Sintering times group (1, 2, 4, 6, 8 and 10 times), sintering temperature group (910, 920, 930, 940 and 950 degrees C), sintering vacuum group (95, 65, 35 and 0 kPa). Transmittance, Y, dominant wavelength and saturation were measured by PR-650 spectra scan spectrocolorimeter.

RESULTSTransmittance of dentin porcelain increased after 6 times repeated sintering. Transmittance of enamel porcelain increased first after the second sintering, and then became decreasing when sintering more than 2 times. Transmittance of enamel porcelain deceased when sintering temperature was lower than standard. Decrease of sintering vacuum caused the transmittance of dentin and enamel porcelain decreased. The changing of value was coordinated with transmittance. Dominant wavelength and saturation had negative correlation with sintering times and temperature, and positive correlation with vacuum.

CONCLUSIONSintering times, temperature and vacuum all had prominent effects on the translucency and color of dental porcelain. Comparing with dentin porcelain, enamel porcelain was more sensitive with the modification of manufacture technique.

The cytokines of acute leukemia (AL) patients have certain expression patterns, forming a complex network involved in diagnosis, progression, and prognosis. We collected the serum of different AL patients before and after complete remission (CR) for detection of cytokines by using an antibody chip. The expression patterns of cytokines were determined by using bioinformatics computational analysis. The results showed that there were significant differences in the cytokine expression patterns between AL patients and normal controls, as well as between acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). In confirmatory test, ELISA revealed the expression of uPAR in AL. Moreover, the bioinformatic analysis showed that the differentially expressed cytokines among the AL groups were involved in different biological behaviors and were closely related with the development of the disease. It was concluded that the cytokine expression pattern of AL patients is significantly different from that of healthy volunteers. Also, differences of cytokine expression patterns exist between AML and ALL, and between before and after CR in the same subtype of AL, which holds important clinical significance for revealing disease progression.

OBJECTIVETo explore Chinese medical syndrome distribution features of Japanese encephalitis (JE), and to analyze its correlation between syndromes and features of etiologies and pathogeneses.

METHODSRecruited were 277 patients with confirmative diagnosis of JE from Wuhan Medical Treatment Center, Children's Hospital Affiliated to Chongqing Medical University, Fifth People's Hospital of Guiyang City, Hangzhou Sixth People's Hospital, and Chengdu Hospital of Infectious Diseases between July to September 2012. Chinese medical syndrome distribution features were summarized from their general materials and detailed records of clinical data, including medical history, symptoms and signs, tongue fur, and pulse figures.The frequency of symptoms and signs was calculated according to mild, ordinary, severe, extreme severe degrees. The distribution of Chinese medical syndromes was summarized. And its correlation between syndromes and features of etiologies and pathogeneses were analyzed.

RESULTSAfter clustering analysis, Chinese medical syndromes of JE could be categorized as four groups: toxicity accumulation in Fei and Wei syndrome (TAFWS), brain collateral impaired by poison syndrome (BCIPS), depression of toxicity in the pericardium syndrome (DTPS), exhaustion of yin and yang syndrome (EYYS). BCIPS and DTPS were dominated, accounting for 74.0% (205 cases). The main causes covered evil of summer heat [accounting for 92.42% (256/277 cases)], heat [accounting for 87.73% (243/277 cases)], and toxin [accounting for 99.64% (276/277 cases)].

CONCLUSIONSThe four Chinese medical syndrome types of JE met Chinese medical clinical features of encephalitis. It is induced by infestation of dampness-heat, resulting in toxicity accumulation in Fei and Wei, brain collateral impaired by poison, depression of toxicity in the pericardium. Yin fluid and blood is exhausted as time goes by. Qi and yin are impaired to form intermingled deficiency and excess, and finally causing exhaustion of yin and yang.

The purpose of this study was to develop a quantitative and objective method for evaluating neurological deficits in mice with focal cerebral ischemia. After middle cerebral artery occlusion (MCAO), the neurological deficits were evaluated 24 h later. We measured the mean angles, dominant angles and turns in a hanged test in which the mice were sticked on the wall, and the holding angles in an inclined plane test as well, Then we determined the cerebral infarct volumes, neuron density in hippocampus, cortex and subcortical areas 24 h after MCAO. The correlations among infarct volume, neuron density and neurological deficits were analyzed. We also compared the quantitative method with two typical complex methods of behavioral assessment. The effect of [pranlukast, 4-oxo-8-[p-(4-phenylbutyloxy) benzoylamino]-2-(tetrazol-5-yl)-4H-1-benzopyran hemihydrate] (ONO-1078), a neuroprotective agent, on ischemic injury was observed using this method. We found that the variables measured by both quantitative and typical behavioral methods significantly changed in the ischemic mice, and correlated with the infarct volumes and neuron densities. The quantitative variables well correlated with those of typical behavioral assessment, too. ONO-1078 inhibited ischemic injury and reduced the total scores of quantitative assessment. Thus, the quantitative method we developed is useful in evaluating neurological deficits of focal cerebral ischemia with the advantages of objectivity, quantification, simplicity and non-invasion, and can be used in the evaluation of neuroprotective effects of drugs.
