This study was aimed to find the optimal conditions for seed propagation of Fritillaria cirrhosa in the plateau region in order to summarize the best sowing time and method of artificial propagation. Seeds were stored in appropriate environment. After the seeds matured, the seedbed of F. cirrhosa was treated with cattle dung humus and small shed. The results showed that early March is the best sowing time and cattle dung humus with a thickness about 1 cm is the best coving for propagation of F. cirrhosa; the growing period of film propagation (FP) is about 160 days each year compared with that of control about 50-60 days, respectively. It was concluded that the propagating seeds in plastic greenhouses by using cattle dung humus as planting substrates, using sunshade nets for shading and keeping humidity by spraying can effectively prolong the growing period, improve the retention rate of annual bulbs and the production of F. cirrhosa.

Objective To investigate formalin-induced nociceptive behavior and c-fos expression of interbrain following stellate ganglionic block (SGB) in rabbits. Methods Catheters were inserted closely to right stellate ganglia in rabbits by operation.One week later,twenty-four rabbits were randomly divided into three groups, each group containing 8 animals. groups A,B and C received 0.5ml of normal saline,3% formalin and 3% formalin stimulation by intraplantar injection , respectively. 10 minutes before stimulation,0.5 ml of 0.25% bupivacaine was administered via the catheter in group B, while in groups A and C 0.5 ml of normal saline was applied. Nociceptive behavior was observed for 1 hour using weighted pain score. 2 hours after stimulation, whole interbrain was removed to immunohistochemically detect the expression of c-fos. Results Formalin-induced nociceptive behavior in phase 2 was relieved following SGB, c-fos expression level of hypothalamus in group B was significantly lower than that in group C(P0.05). Conclusion SGB could relieve formalin-induced nociceptive behavior, and downregulate formalin-induced c-fos expression of hypothalamus, which may be related to the mechanisms of SGB for the treatment of inflammatory pain.

Objective: To investigate formalin-induced inflammatory nociceptive response and Fos expression of interbrain following stellate ganglion block (SGB) in rabbits. Methods: Catheters were inserted closely to right stellate ganglia in rabbits.One week later,twenty-four rabbits were randomly divided into three groups of 8 each:sham group,SGB group and control group,receiving 0.5ml of normal saline,3% formalin and 3% formalin stimulation by intraplantar injection into the right front paw, respectively. ten mins before stimulation,0.5ml of 0.25% bupivacaine was administered via the catheter in SGB group,while 0.5ml of normal saline in sham group and control group. Nociceptive response was observed for 60min using weighted pain score. Local inflammatory response was measured by histopathology, the expression of Fos of interbrain was measured with immunohistochemistry 2 hours after stimulation. Results: Formalin-induced nociceptive behavior in phase 2 and local inflammatory response were relieved following SGB; the average numbers of Fos-positive neurons of hypothalamus in SGB group was lower than that in control group( P 0.05). Conclusion: SGB suppresses formalin-induced Fos expression of hypothalamus.

Objective To determine the effect of endomorphin (EM) on colonic electromyography activity and investigate the pathogenesis of slow transit constipation (STC). Methods An experimental rat model of slow transit constipation was constructed by contract laxatives mixed with the feed. The changes of colonic electromyography and reaction to endomorphin 1 and endomorphin 2 were examined. Results Compared with the control group, the frequency and amplitude of slow wave in cathartic colon rats were decreased significantly. Endomorphin 1 and endomorphin 2 significantly decreased the amplitudes of slow wave, but did not change the frequencies of slow wave. The effect of endomorphin 1 was more pronounced than that of endomorphin 2, which could be reversed by the morphine antagonist Naloxone in concentration-dependent manner. Endomorphin could not block the stimulating effect of acetylcholine. Conclusions Endomorphin can influence the colonic electromyography activity and intestine motility of cathartic colon rats, and may be involved in the pathologic mechanism of slow transit constipation.

Objective To explore the effects of electro-acupuncture combined with surface gastric pacing on gastrointestinal dysfunction for patients with spinal cord injury (SCI).Methods Seventy-five SCI patients with gastrointestinal dysfunction were divided randomly into an electro-acupuncture group (group A),a gastric pacing treatment group (group B) and a group for which electro-acupuncture was combined with gastric pacing (group C).There were 25 cases in each group.Members of group A were given 30 minutes of electro-acupuncture per day ; those of group B had 30 minutes of gastric pacing treatment twice per day ; group C was provided with both 30 minutes of electro-acupuncture and one 30-minute gastric pacing treatment per day.All of the interventions lasted ten days.Before and after the treatment,all patients were assessed using a clinical symptoms score and with electrogastrograms,and any adverse effects were observed.Results There was a significant improvement in upper abdominal pain and epigastric discomfort,bloating and early satiety,nausea,vomiting,as well as belching and loss of appetite in each group after treatment.Before treatment there was no significant difference in the average clinical symptom scores of the three groups.After treatment the values had decreased,and those of group C were significantly lower than group A or B.The average scores of groups B and A were not significantly different.The electrogastrogram results showed than after treatment there was significant improvement in N％ and T％ in groups A and B,and also significant improvement in N％,B％ and T％ in group C compared to before treatment.Group C's improvements were all significantly greater than those observed in groups A and B.Conclusion Electro-acupuncture or gastric pacing alone can give some improvement in gastrointestinal function and its electrophysiological indicators,but their combined effects are better than when either is used alone.

Objective:To summarize the clinical experience of surgical treatment abdominal gastrointestinal foreign body in children, thus to provide a theoretical basis for clinical decision-making.Methods:The clinical data, including age distribution, clinical manifestations, surgical treatment strategy and prognosis, from 60 children with abdominal gastrointestinal foreign body treated by operation in Children's hospital of Hu′nan Province from January 2015 to June 2020, were retrospectively analyzed. Among the 60 children, 38 males and 22 females, with a median age of 2.9 years. Observation data included the type and location of foreign bodies in the digestive tract, clinical manifestations and surgical methods, operation time, intraoperative blood loss, postoperative hospital stay. The following-up time was 6 months to 2 years by telephone or clinic. The short/long-term complications was observed.Results:Children under 3 years old accounted for 56.7%. Types of foreign bodies included magnetic foreign bodies, sharp objects[paper clips, nails, screws, fish bone and others, etc], crystal ball, jujube pit, gastric hair stone, batteries and badminton holder. The foreign bodies were mainly located in stomach and small intestine. Abdominal pain and vomiting were the most common symptoms. The patients of foreign body with long residence time had peritonitis such as fever and abdominal pain, among 21 cases were combined with gastrointestinal perforation. There were varieties kind of operaion methods, including gastrointestinal incision and foreign bodies removal( n=22), appendectomy and foreign bodies removal( n=7), repair of gastrointestinal perforation( n=6), intestinal resection and anastomosis( n=17), intestinal resection plus enterostomy( n=5)but whose fistula was closed after 3 months, lateral wall of rectum repair( n=3). Fifty-two patients underwent common open abdomen operation, 8 patients underwent laparoscopic operation. The operating time was(93.5±19.3) min. Intraoperative blood loss was(20.2±4.3) mL. The postoperative hospitalization was 13(5, 19) d. The postoperative complications occurred in 3 patients who were nonoperative treatment recovery. Conclusions:Magnetic foreign body, sharp foreign body, crystal ball, jujube nucleus and corrosive foreign body are the main causes of digestive tract obstruction and perforation in children. Individualized operation plan should be selected as soon as possible according to the number of foreign bodies, retention position and whether or not digestive tract perforation.
