Objective: To search for a best method for management mandible fractures by evaluating the effects of different treatments.Methods: We retrospectively analyzed 148 cases of mandible fractures treated in our department from January 1996 to June 2007.Results: Among the total number,134 cases were restored to normal occlusion,while 6 cases experienced local occlusive disfunction and 8 malocclusion.The effect of treatment was correlated with the types of fracture and methods of diaplasis.Conclusion: Mandible fractures should be treated with a new concept of combined and sequential multidisciplinary methods.Sound diaplasis followed by reliable fixation can produce a satisfying curative effect.At present,intermaxillary elastic traction with internal titanium plate fixation is the most effective method for the management of mandible fractures.

Objective: Maxillary and mandible fractures are severe intermaxillary injuries,frequently involving other vital organs,and usually difficult to be treated.This study discusses the treatment of maxillary and mandible fractures.Methods: We retrospectively analyzed the clinical data of 39 cases of maxillary fractures and/or mandible fractures.Results: Of the 39 cases,34 males,5 females and 84.64% aged from 20 to 50,87.17% were caused by vehicle accidents,and 94.87% were accompanied by injuries of other parts of the body.After surgical treatment,78.95% gained normal or basically normal ocular esthetic results and 68% achieved good or improved facial esthetic results.Conclusion: The results of treatment are closely related with the type and severity of fracture and the time and plan of treatment.Preoperative CT scanning and facial profile three-dimensional reconstruction are necessitated for a thorough evaluation of the fractures and an analysis of the causes and extent of facial and ocular changes.The best treatment plan for maxillary and/or mandible fractures would include anatomic reduction by surgery,intermaxillary elastic traction and rigid internal fixation with the Ti plate.

Objective To investigate the comparison of clinical effects between two models of alimentary reconstruction after total gastrectomy in the elderly patients with gastric cancer.Methods 70 patients receiving alimentary tract reconstructions of Orr-type Roux-en-Y reconstruction (Orrtype,40 cases) and modified Brawn Ⅰ (30 cases) from January 2007 to December 2012 were retrospectively analyzed.The operative time,amount of bleeding,early postoperative complications and mortality,food intake,nutritional status and alimentary tract function were compared at 6 months after surgery.Results There were no significant differences between the two methods in the operative time [(198.8±14.0)min vs 233.5±30.7)min,t=-l.697,P＞0.05)],amount of bleeding [(420 ± 43) ml vs (340 ± 25) ml t =-1.956,P ＞ 0.05],and early postoperative complications [(17.5％ vs 16.7％),x2 =0.008,P＞0.05].However,times of liquid diet intake and semi liquid diet intake of the Orr-type reconstruction method was comparatively shorter than that of the modified Brawn Ⅰ [(4.8±2.1) d vs (7.6±2.4) d,and (9.5±3.6) d vs (11.5±3.7) d,t=-5.192,P＜0.05)].Nutritional status (weight,hemoglobin,total serum proteins and serum albumin) at 6 months after operation showed no significant differences between the two methods.But constituent ratio of Visick scores Ⅰ-Ⅱ of Orr-type was bigger than that of modified Brawn Ⅰ (86.7％ vs 62.5％,x2 =5.063,P＞0.05).Conclusions Orr-type Roux-en-Y reconstruction method can avoid reflux esophagitis,and the procedure is more simple than the modified Brawn Ⅰ method.Therefore,Orr-type Roux-en-Y reconstruction should be recommended as an adoptable method of digestive reconstruction after total gastrectomy for gastric cancer in the elderly patients.

OBJECTIVETo investigate the predictive value of preoperative Glasgow prognostic score (GPS) for the postoperative complications and survival in patients with colorectal cancer (CRC) undergoing laparoscopic radical resection.

METHODSThis retrospective study was conducted in the Beijing Hospital between January 2009 and January 2012. A total of 228 patients with primary CRC undergoing laparoscopic radical resection were analyzed. The GPS was constructed based on routine preoperative blood tests of C-reactive protein and serum albumin. The patients were classified into three groups according to GPS (GPS 0, 1, 2 groups). Survival curves were described by the Kaplan-Meier method and compared by the Log-rank test. The univariate and multivariate analyses were performed with the Cox proportional hazard model to identify the influence of GPS on prognosis in patients with CRC undergoing laparoscopic radical resection.

RESULTSPreoperative CRP level was increased in 48 cases (21.1%), and preoperative serum albumin level was decreased in 104 cases (45.6%) in the whole group. These 228 patients were classified into 99, 105 and 24 patients in GPS 0, 1, 2 group respectively. GPS was significantly associated with age, preoperative body mass index (BMI), carcinoembryonic antigen (CEA), CA19-9, tumor location, tumor differentiation and TNM stage (all P<0.05). Postoperative complication rates of GPS 0, 1, 2 group were 6.1%, 14.3% and 70.8% respectively (χ=59.147, P=0.000). Serious postoperative complication rates were 3.0%, 6.7% and 58.3% respectively (χ=65.807, P=0.000). Univariate and multivariate analyses revealed that GPS was an independent risk factor of postoperative complications(HR=21.611, 95%CI: 5.936-78.681, P=0.000) and severe complications (HR=35.833, 95%CI: 7.364-174.355, P = 0.000). The 5-year survival rate was 50% and the average total survival time was 58.2 (95% CI: 54.6-61.7) months in the whole group. The median overall survival time in GPS 0, 1, 2 group was 74.6(95%CI: 70.4-78.7) months, 49.8(95%CI: 45.2-54.4) months and 27.8 (95%CI: 21.8-33.8) months respectively(χ=98.425, P=0.000). The median disease-free survival time was 73.9(95%CI: 69.2-78.7) months, 47.4 (95% CI: 41.6-53.1) months and 19.9 (95%CI: 14.8-25.0) months respectively (χ=91.305, P=0.000). GPS was an independent risk factor of disease-free survival (HR=4.840, 95%CI: 2.413-9.709, P=0.000) and overall survival (HR=6.267, 95%CI: 3.073-12.784, P=0.000).

CONCLUSIONSGPS can be used as an effective predictor of the prognosis for patients with CRC undergoing laparoscopic radical surgery. Higher GPS suggests more postoperative complications and worse prognosis.

To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. The suppression of capsulte on TNF-α secretion was reduced by gradient knockout of gallic acid, cinnamaldehyde, pentagalloylglucose, and pachyman. The promotion of SPL cells proliferation was reversed by gradient knockout of gallic acid, paeoniflorin, cinnamaldehyde, quercetin, and pachyman. The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

This article was aimed to study the therapeutic effects and anti-inflammatory effects of Chinese and west-ern medicine ointment on fungal infection animals. Guinea pig models which were infected with Trichophyton rubrum or Microsporum lanosum were applied to observe the effects of antifungal infections on She-Zhi Qin-Xian (SZQX) ointment by transdermal administration. The ointment is the combination of miconazole nitrate, snake oil and Sophora flavescens which is traditional Chinese medicine (TCM). Simultaneously, the models of croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling were established to observe the curative effect of SZQX ointment. The results showed that the SZQX ointment had a protective role on both guinea pig models. The microscopic scale of localized lesions in infected guinea pigs was significantly decreased (P< 0.01). The effect of SZQX ointment was better than the single using of Chinese or western medicine. The SZQX ointment was also able to significantly reduce the croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling (P< 0.05, or P< 0.01) with distinct anti-inflammatory effect. And the effect of SZQX ointment was superior to the single using of either Chinese or western medicine. It was concluded that the SZQX ointment had significant antifungal infection and anti-inflam-matory effect.

This study was aimed to investigate the effects of high-dose strictosamide injection on cardiovascular sys-tem of anesthetized beagle dogs and to examine the inhibition of strictosamide on ion channels in vitro. Indexes such as changes of systolic blood pressure (Sys), diastolic blood pressure (Dia), mean blood pressure (MBP), heart rate (HR), PR, QRS, QT, QTcb and QTcv at different time points before and after strictosamide injection in dogs were monitored by the polygraph system. The inhibition of strictosamide at different concentrations on hERG potassium channel in CHO-hERG cells and Nav1.5 sodium channel in HEK-293-Nav1.5 cells were measured by whole-cell patch-clamp method. The results showed that compared with the blank control group, Sys, Dia, MBP and HR were obviously declined 15 min after medication in the strictosamide (60, 18 mg·kg-1) group and the vehicle-control group (containing tween-80) (P < 0.05). After medication, all indexes were recovered. Compared to the vehicle-control group, there were no significant differences at different time points in each medication groups. Compared with the blank control group and before medication, the QT interval, QTcb and QTcv were significantly prolonged 15 min af-ter medication in the strictosamide (60, 18, 6 mg·kg-1) group and the vehicle-control group (P< 0.05). When medi-cation stopped, indexes were recovered at certain level. Compared with the vehicle-control group, there were no sig-nificant differences of QT interval, QTcb and QTcv of each medication group at different time points (P> 0.05). The inhibition of strictosamide on hERG potassium channel and Nav1.5 sodium channel were weak with IC50 values of 560.8 μM and > 900 μM, respectively, which were far greater than the positive controls. It was concluded that sin-gle, high-dose intravenous injection of strictosamide may lead to a lower blood pressure, a slower heart rate and a prolongation on the QT interval in beagle dogs, which returned to basal levels when medication stopped. It was spec-ulated that the reduction of blood pressure and the slowing of heart rate were related to tween-80 contained in the vehicle control group. No significant inhibitory effects were detected on hERG potassium channel and Nav1.5 sodium channel in vitro, which suggested that other mechanisms may be involved in strictosamide-induced QT interval pro-longation in animals.
