Aim To observe the effect of new com-pound L11 on the affinity and function of sigma-1 re-ceptor,as well as the mouse acute toxicity and analge-sic effect, so as to provide the experimental basis for its pharmacodynamics and preliminary toxicity evalua-tion. Methods Using binding and function test of sig-ma-1 receptor in vitro, the acute toxicity and formalin model test of mice,as well as the rat chronic constric-tion injury(CCI) model test in vivo,the effects of L11 on the inhibitory rate and function of sigma-1 receptor, LD50,lifting/licking time of mice and mechanical pain threshold of rats were respectively measured to evaluate the analgesic effect and mechanism of L11. Results The inhibitory rate and Kiof L11 on the sigma-1 recep-tor were 103.07% and 4.81 nmol·L-1,respectively. The Kivalue was 8.10 nmol·L-1while adding pheny-toin (sigma-1 receptor allosteric modulator). The in-tragastric administration of L11 in mice was 1 680.03 mg·kg-1LD50,and the 95% confidence interval was (1 559.35 ~1 819.40) mg·kg-1. Compared with model group, the II phase lifting/licking time of mice was significantly reduced and the mechanical pain threshold of rat obviously increased by L11. Conclu-sions The new compound L11 has high affinity to sig-ma-1 receptor, which belongs to the antagonist of sig-ma-1 receptor;L11 is less toxic to intragastric adminis-tration and has obvious analgesic effect on the formalin model of mice and CCI model of rats, which may be relative with the sigma-1 receptor antagonism.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

OBJECTIVETo investigate the clinical efficacy and safety of caffeine citrate and aminophylline in the treatment of primary apnea in premature infants.

METHODSThe clinical data of 125 premature infants with primary apnea from March 2013 to March 2014 were retrospectively analyzed. According to the therapeutic strategy, the patients were divided into caffeine citrate group (n=65) and aminophylline group (n=60). The overall response rates and adverse reaction rates in the two groups were compared.

RESULTSThe overall response rate in the caffeine citrate group was 86% (56 cases), which was significantly higher than that in the aminophylline group (72%, 43 cases) (P<0.05). The adverse reactions in the caffeine citrate group included tachycardia (1 case), restlessness (5 cases), feeding intolerance (7 cases), electrolyte disturbance (2 cases), and high blood glucose (5 cases), the incidence of which was significantly lower than that in the aminophylline group (P<0.05).

CONCLUSIONSCaffeine citrate is more effective and causes fewer adverse reactions than aminophylline in the treatment of primary apnea in premature infants.

OBJECTIVETo present a method of quantitative diagnosis of craniofacial skeleton deformities based on three-dimensional computed tomography (3D CT).

METHODS20 cases with facial asymmetric deformities underwent 3D CT and the 3D images were reconstructed by Mimics 10.0 (Belgium). Anatomical landmarks were located and the coordinate of the landmarks obtained. Axial images of 1 patient with Romberg disease was used as representative case. The differences in the distance between the right landmarks and the left were calculated and analyzed.

RESULTSThe measurement results were not significantly different between two stages with an interval of 4 weeks ( P > 0.05), showing a reproducible resutls. The deviation of landmarks at facial midline increased gradually from upward to downward, reaching (2.63 +/- 0.54) mm at menton point. Paired landmarks showed asymmetry in three dimensions, especially gonion point on the left side, which was deviated 10.21 mm inward, 9.26 mm forward, 6.30 mm upward, compared to the opposite side.

CONCLUSIONSThe method of 3D CT quantitative analysis can provide precise information in the diagnosis and treatment planning of facial asymmetry deformity.

Objective To explore the effects and safety of hemoperfusion(HP) therapy on tetramine poisoning in infants.Methods Thirty-five infants with tetramine poisoning were divided into two groups: HP group(n=18) and non HP group(n=17).The changes of blood tetramine concentration and clinical symptom improving of both groups after the treatment were observed together with the adverse effects of HP group.Results The average blood tetramine concentration of HP group was higher than that of non HP group(342.2?333.4 vs 117.9?50.8 ?g/L,P

OBJECTIVETo investigate the effects of alcohol intake on penile structure and function in rats.

METHODSThirty adult male Wistar rats were randomly divided into two groups: control group and alcohol intake group. They were administered with 2 mL of normal saline and 40% alcohol solution respectively through gastric tubes every day. Three months later, the animal model of alcohol intake was evaluated by modified Nayagida's method, and the effects of alcohol on the rats were studied by sexual behavior, the number of apomorphine-induced penile erection, level of testosterone in the sera, and the content of penile smooth muscle.

RESULTSThe scores of animal model of alcohol intake evaluated by Nayagida's method were 0.66 +/- 2.05 in the control group and 9.26 +/- 5.50 in the alcohol intake group (P < 0.05), which indicated that an animal model of alcohol intake was successfully established. Sexual behavior, the number of apomorphine-induced penile erection, testosterone level in the sera, and the content of penile smooth muscle of the alcohol intake group were all statistically different as compared with the control group (P < 0.05).

CONCLUSIONAlcohol intake induces sexual dysfunction in rats, which may be due to the decline of testosterone level in the sera and decline of penile smooth muscle.

OBJECTIVETo determine the therapeutic efficacy and elucidate the probable pharmacological mechanism of Zhizhuwan (ZZ), a known formula for GI/Dysmotility and constipation in Traditional Chinese medicine, in managing constipating diabetes mellitus (DM).

METHODSubjects, composed of both males and females, ranged from 55 to 76 years of age, and had constipating DM. Subjects with severe colon, rectum, heart, renal, or hepatic disease, obesity and those on medications known to alter gastrointestinal motility were excluded. 28 healthy subjects were also recruited. The study group (n = 28) received 90 g per day of ZZ and the control group (n = 28) received 30 mg per day of cisapride for a 1 month period. Conservative therapy was similar in both groups and administered by a person blinded to randomization code. Patients were assessed pre-treatment and post-treatment by a blinded interviewer. A constipation visual analogue scale (CVAS) was constructed to evaluate the patients' constipation status. To analyze neuropeptides motilin (MTL), vasoactive intestinal polypeptide (VIP), substance P (SP) levels in plasma, a radioimmunoassay technique was adopted. Data were analyzed for treatment effects using the "t" test.

RESULTBase line characteristics were similar in both treatment groups. There were significant effects on symptom relief, increases in serum SP level, and decreases in VIP level in both groups (P < 0.05). ZZ was significantly more effective than cisapride in ameliorating patients' subjective symptoms of defecating and stool frequency, and increasing serum SP level (P < 0.05).

CONCLUSIONZZ is beneficial in constipating DM via increasing SP levels and decreasing VIP levels of serum.
