Objective To observe the effect of Ginkgo biloba extract (EGb) on intestinal function after spinal cord injury (SCI) in rats. Methods 36 Sprague-Dawley rats were randomly divided into group A (n=12), group B (n=12) and group C (n=12). SCI model was established with Allen's mode (10 g×25 mm) at T10. 30 minutes later, group A was intraperitoneally injected with methylprednisolone 30 mg/kg every 24 hours; group B was injected with Shuxuening injection (EGb) 1.75 mg/kg every 24 hours; group C were injected with equal volume of saline. The slow wave of intestinal smooth muscle was measured, the activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in serum were determined 1 day, 3 days and 7 days after modeling, while intestinal tissue was tested with HE staining. Results The amplitude and frequency of the myoelectric slow wave increased in the groups A and B 3 and 7 days after modeling compared with those in the group C (P<0.05); meanwhile, the activity of SOD increased and content of MDA decreased in the groups A and B (P<0.05). The HE scores decreased in the groups A and B compared with those in the group C (P<0.05), which presented that the inflammatory exudation was mild, the hemorrhagic spot was few and the area was limited. The intestinal villous of the group C was blunt with large infiltration of inflammatory cells and inflammatory exudate on the mucosal surface. Conclusion EGb can improve the recovery of intestinal function in rats spinal cord injury through antioxidant.

OBJECTIVETo analyze the radiological parameters of the conservatively in treating distal radius fracture and investigate whether the final re-displacement can be predicted after primary reduction.

METHODSFrom January 2013 to June 2014,212 patients with distal radial fracture conservatively were treated in our hospital, 107 patients of them were excluded because of their incomplete radiological parameters;the remaining 105 patients were available for radiological were assessed after injury, there were 56 male patients and 49 female patients in this study, the average age of the patients was 51 years old (ranged from 22 to 80 years). According to AO classification, there were 47 cases of type A2 and C1, and 58 cases of type A3, C2, C3. All patients were treated by closed reduction and below-elbow cast immobilization for 4 to 6 weeks. All patients were followed up for 3 to 6 months (means 4.5 months) by X-ray, all fractures were healed. Standard AP and lateral radiographic examination was conducted before reduction and after reduction and bony consolidation,the dorsal angulation and the radial angle were measured at each time point. The linear regression was used for the analysis to find out whether the final re-displacement can be predicted after primary reduction.

RESULTSAmong 105 patients,the significant correlations were found for the dorsal angulation between the reduction time and the end time (r = 0.82) and for the radial angulation between the reduction time and end time (r = 0.85).

CONCLUSIONThe dorsal angulation and the radial angulation after complete healing can be predicted from linear the regression functions. Due to the possibility of predicting the end result, whether the fracture should receive further conservative treatment or surgical treatment can be decided immediately.

AIMTo investigate the effects of fungal elicitors on inophyllums production in suspension cultured cell of Calophyllum inophyllum Linn.

METHODSThe pathogen of leaf spot disease of C. inophyllum L. was isolated and prepared as fungal elicitor. The fungal elicitor was added to the medium with different concentrations and culture period. Their effects on biomass and inophyllums content of the suspension of cultured cells were studied.

RESULTSThe optimum effects of S-I fungal elicitor concentrations on inophyllums content was 60 mg GE x L(-1). Adding the fungi elicitor into the cell suspension culture system at stationary phase (being cultured for 18 days) resulted in a highest inophyllum content of 59.174 mg x L(-1) at the 3rd day with 27% higher than control. Fungal elicitor treatment promoted the inophyllums accumulation in medium.

CONCLUSIONAdding the Stagonospora curtisii (Berk.) Sacc. to the medium was effective approaches to enhance inophyllums yield in the suspension of C. inophyllum L culture cell.

Objective: To analyze the effect of breakfast nutrition quality on the satiety among young white-collar workers. Methods: A total of 278 subjects were recruited from two cities, Shenyang and Chongqing, in June 2015. The inclusion criteria: white-collar workers aged 25-45 years involved mainly in office work, who did not experience major changes, and individuals who should follow the study protocol and sign the informed consent form. The study employed a three-phase crossover design trial. Each participant received nutritional-adequate breakfast, nutritional-inadequate breakfast, and no breakfast treatment on the basis of assignment to one of three sequences. The breakfast time was once a week and then changed, all participants underwent the tests for three successive weeks. At last, we compared the effect of participants to consume different nutritional quality on satiety sense and hunger sense. Results: A total of 232 participants completed three successive breakfast intervention studies, the age of participants was (35.2 ± 7.9) years, comprised of 48.7% male (n=113). The numbers of participants of aged 25-35 year-old and aged 36-45 were 118 and 114, respectively. Satiety scores of nutrition-adequate breakfast group, nutrition-inadequate breakfast group and no breakfast group were 63.5±14.7, 53.1±10.2 and 36.4±7.2, respectively (P<0.05). In nutrition-inadequate breakfast group and no breakfast group, male subjects scored significantly higher than female subjects (50.9±10.5 vs 46.6±9.4, 35.2±8.3 vs 31.8±5.4) (P<0.05). And, participants aged 25-35 year-old. got satiety score significantly higher than aged 36-45 (51.3±11.0 vs 45.6±12.1, 34.1±6.8 vs 32.5±7.9), the difference was statistically significant (P<0.05). The scores of hunger in the group of nutrition-adequate breakfast, nutrition-inadequate breakfast and no breakfast were 26.3 ± 8.0, 35.1 ± 11.2 and 57.3 ± 17.0, respectively (P<0.05). Conclusion The nutrition quality of breakfast affects the satiety of young white-collar workers. The better the nutrition quality of breakfast is, the higher the satiety score and the lower the hunger score become. Compared with women and participants aged 36-45 year-old, men and those aged 25-35 year-old get satiety sense more easily.

OBJECTIVETo evaluate the clinical effects by comparing three different fixation methods: tension band, hollow lag screw and anatomical plate.

METHODSFrom January 2010 to January 2012, 82 patients with olecranon fractures who underwent surgical treatments were followed-up. All the patients were divided into three groups: tension band fixation group (group A), hollow lag screw fixation group (group B), anatomical plate fixation (group C). In group A, there were 35 patients, including 19 males and 16 females, ranging in age from 32 to 49 years old, with an average of (43.6 ± 8.7) years old, and the patients were treated with tension band fixation. According to Colton classification, there were 5 cases of type I, 3 cases of type II A,19 cases of type II B, and 8 cases of type II C in group A. Among 20 patients in group B, there were 13 males and 7 females, ranging in age from 27 to 50 years old, with an average of (41.5 ± 9.3) years old. The patients in group B were treated with hollow lag screw fixation. According to Colton classification, there were 4 cases of type I, 4 cases of type II A, and 12 cases of type II B in group B. In group C, there were 27 patients totally, including 15 males and 12 females, ranging in age from 30 to 55 years old, with an average of (38.2 ± 6.2) years old. The patients in group C were treated with anatomical plate fixation. According to Colton classification, there were 4 cases of type II B, 13 cases of type II C, and 10 cases of type II D in group C. The Fracture healing time, complications and functional recovery were retrospectively observed and recorded.

RESULTSAll the patients were followed up, and the duration ranged from 8 to 24 months, with an average of 15 months. The average healing time of patients in group C was the longest among three groups. The flexion-extension and rotation activities of elbow joint in group B and C were better than that in group C. According to Broberg & Morrey score system, the therapeutic effects of patients in group A and B were better than that of group C. In group C, 2 patients had incision infections, 6 patients complained of foreign body sensation, 1 patient got a delayed fracture healing, and 1 patient had the heterotopic ossification. There were no occurrences of incision infections in group A and B; internal fixation loosening occurred in 3 patients in group A and 2 patients in group B; delayed fracture healing occurred in 2 patients in group A and 2 patients in group B; and skin bursa formation occurred in 6 patients in group A and 1 patient in group B.

CONCLUSIONAll the three ways are effective methods for the treatment of olecranon fractures. Fixation methods should be selected depending on the type of fracture.

BACKGROUNDDifferent diagnostic and grading systems of conjunctivochalasis have resulted in apparent disparity between the prevalence rates of recent population-based studies. This study aimed to investigate the disparity between 4-level system cited from Meller and Tseng in 1998 (abbreviated here as Meller's system) and 5-level system modified from Meller's system cited from Zhang and associates (abbreviated here as Zhang's system) regarding the diagnosis and the patients' preferences for the treatment of conjunctivochalasis in the general population.

METHODSA total of 546 senile residents living in the Guiyangyuan community of Shanghai, China, participated in the study. The diagnostic criteria for conjunctivochalasis were based on two diagnostic grading systems: Meller's system and Zhang's system, which was modified from Meller's system. The participants' preference regarding medical treatment for conjunctivochalasis was determined according to the response to a question. One year later, a follow-up interview determines whether the patient had undergone surgery for conjunctivochalasis.

RESULTSWith Meller's system, 398 participants were confirmed as having conjunctivochalasis, and the prevalence rate was 72.89%. According to Zhang's system, only 213 participants were diagnosed as having conjunctivochalasis, and the prevalence rate was 39.01%. A total of 109 eyes underwent medical treatment or surgery for conjunctivochalasis in the following year, including eight eyes that were diagnosed as grade II and 101 eyes that were diagnosed as grade III according to Meller's system and five eyes that were diagnosed as grade I, 55 eyes that were diagnosed as grade II, 31 eyes that were diagnosed as grade III, and 18 eyes that were diagnosed as grade IV according to Zhang' system.

CONCLUSIONDiagnoses of conjunctivochalasis using Zhang's system are more consistent with patient requests and the medical treatment strategies used than diagnoses made using Meller's system.

BACKGROUNDThe crescent excision of the inferior bulbar conjunctiva has been advised as a surgical procedure in the management of conjunctivochalasis refractory to medical treatments. However, it is difficult for this procedure to design how much conjunctival tissue should be excised. This study aimed to present a quantitative locator for conjunctiva resection and evaluate its effect on the treatment of conjunctivochalasis (CCh).

METHODSPoly β-hydroxyethyl methacrylate resin/β-hydroxyethyl methacrylate (HEMA, water gel) was used as the material to make the quantitative locator which was designed to suit the specific patient. Forty-six patients with bilateral symptomatic CCh were included in this prospective study. Of the patients, while the right eye underwent the popularly used crescent-shaped conjunctiva resection (group I), the left eye was treated with conjunctiva resection assisted by the quantitative locator (group II). International Ocular Surface Disease Index (OSDI), scores of remnant conjunctiva fold, complications and conjunctival cut healing, height of tear meniscus, tear break-up time (BUT), and time of surgery were evaluated. Tasting chloromycetin test (TCT) was used to evaluate how the lacrimal duct worked.

RESULTSOSDI in group II (8.82 ± 2.36) was significantly lower than that in group I (14.67 ± 2.21) (t = 12.22, P < 0.01). The amount of conjunctiva fold remaining in group II was less than that in group I. Scores of remnant conjunctiva fold in group I were significantly higher than those in group II (t = 31.85, P < 0.01). While evaluation scores of conjunctival cut healing in group I were lower than those in group II, scores of complication in group I were significantly higher than those in group II at 8 weeks after surgery (t = 89.60, P < 0.01). There was no significant difference in eyes with normal BUT (χ(2) = 0.031, P = 0.985) between the two groups, as the case was in eyes with positive TCT (χ(2) = 0.14, P = 0.930) and in eyes with normal height of tear meniscus (χ(2) = 0.48, P = 0.780). Mean surgery time in group II ((17.11 ± 2.08) minutes) was significantly shorter than that in group I ((25.22 ± 4.78) minutes) (t = 13.84, P < 0.01).

CONCLUSIONA quantitative locator can be used as an effective, safe, and less time-consuming instrument to facilitate conjunctival excision for symptomatic CCh treatment.

OBJECTIVETo investigate a drilling guide in the treatment of acromioclavicular joint dislocation with closed reduction and Kirschner fixation and explore the therapeutic effect.

METHODSFrom June 2008 to December 2009, 36 patients with acromioclavicular joint dislocation (Tossy III) were treated with closed reduction and Kirschner fixation using a self-designed drilling guide as well as percutaneous repair of acromioclavicular joint. Among the patients, 24 patients were male and 12 patients were female,ranging in age from 20 to 61 years, averaged 38.6 years. The duration from injury to operation ranged from 3.5 to 72 h,with a mean of 15.2 h. No clavicle fracture was found in all cases. The operative time, intra-operative bleeding and therapeutic effects were observed.

RESULTSThere were no complications including neurovascular problems. The mean operating time were 20 min,mean blood loss were about 10 ml. According to the observation of postoperative X-ray examination, all Kirschners in acromioclavicular joint were in place. All Kirschners were removed in 6 postoperative weeks. All the patients were followed up ranging from 2 to 26 months (averaged 14.3 months). According to the Karlsson standard,22 patients got an excellent result, 13 good and 1 poor.

CONCLUSIONThis method has following advantages: easy operation and fixation; minimum injuries to articular surface; and which would be widely used in clinical practice.
