Objective To observe the therapeutic effect and prognosis of patients with severe traumatic craniocerebral injury treated by Lund program combined with Angong Niuhuang pill. Methods A prospective study was conducted. Forty-nine patients with severe traumatic craniocerebral injury were divided into two groups:combined treatment group (25 cases) and control group (24 cases). All the patients in the two groups received conventional therapy. Additionally, the combined treatment group was treated by the Lund program combined with Angong Niuhuang pill, the patients after admission into the intensive care unit (ICU), indwelling of gastric tube was immediately given (the tube inserted and retained through mouth in cases with cranial base bone fracture), one pill of Angong Niuhuang was fed nasally twice a day for consecutive 15 days. Before and after treatment, the intracranial pressure (ICP), cerebral perfusion pressure (CPP), Glasgow coma scale (GCS) score, the mean flow velocity of middle cerebral artery (MCA), and the incidence of complication, clinical efficacy and prognosis in the two groups were observed. Results There were no statistically significant differences in the levels of ICP, CPP, GCS score and the average flow velocity of MCA before treatment and the first day after treatment between the two groups. Beginning from 3 days after treatment, the degrees of improvement in the above indexes in the combination treatment group became much better than those in the control group [ICP (mmHg, 1 mmHg=0.133 kPa):16.78±4.50 vs. 18.80±5.67, CPP (mmHg):71.35±1.63 vs. 58.11±1.47, GCS score:9.53±0.38 vs. 8.23±0.44, the mean blood flow velocity (cm/s):152.23±3.33 vs. 178.86±5.23, all P<0.05]. The incidences of complications such as hyperpyrexia [8.0%(2/25) vs. 41.7%(10/24)], hyperspasmia [12.0%(3/25) vs. 45.8%(11/24)] and cerebral hernia [8.0%(2/25) vs. 33.3%(8/24)] in the combined treatment group were significantly lower than those in the control group (all P < 0.05). The rates of renal failure, electrolyte imbalance and pulmonary infection in combined treatment group were also lower than those in the control group, but the differences were not statistically significant (all P>0.05). The rate of good therapeutic effect in combination treatment group was obviously higher than that of the control group [72.0% (18/25) vs. 33.3% (8/24), P < 0.05], while the mortality was markedly lowered [8.0% (2/25) vs. 33.3% (8/24), P < 0.05]. Conclusions The combination of Lund program and Angong Niuhuang pills for treatment of patients with severe traumatic craniocerebral injury can reduce the degree of increase of ICP at early stage, ameliorate cerebral edema and its development, elevate CPP and improve cerebral ischemia and hypoxia. In the aspects of controlling hyperpyrexia, decreasing limbs twitches and the incidence of hernia, elevating the quality of patients' life, reducing mortality and improving prognosis, the therapy has relatively good therapeutic effects.

Objective: To study the antiemetic effect of the ethyl acetate extract with ethanol extraction of Galangal (hereinafter referred to as galangal extract) in allotriophagic Kaolin model rats.Methods: The rats were administered respectively with chemical drug cisplatin and apomorphine, and received the rotation stimulation as well.Three types of allotriophagic Kaolin models were established, and apomorphine, ondansetron and metoclopramide were used as the control drugs.The experimental rats were divided into 3 groups at low, medium and high dose of Galangal extract with prophylactic effect.The antiemetic effect was observed after the treatment.Results: Chemical drug cisplatin (3.0 mg·kg-1, intraperitoneal injection) and apomorphine (3.2 mg·kg-1,subcutaneous injection) and the rotation stimulation (centrifugal force of 3.4×g,60min) could induce allotriophagic vomiting in rats.The galangal extract at low (1 500 mg·kg-1), medium (4 500 mg·kg-1) and high (9 000 mg·kg-1) dose all fail to effectively inhibit the allotriophagic Kaolin behavior of rats caused by cisplatin, apomorphine and rotation(P>0.05).Conclusion: Galangal extract can not effectively inhibit the vomiting of allotriophagic Kaolin model rats.Probably, there is no correlation between the pharmacological effects of galangal extract and substance P, 5-hydroxytryptamine, dopamine as well as receptive zone of chemical vomiting inhibition.

Aim To observe the effect of dopamine (DA) and its antagonist on the electrical activities of pain excitation neurons (PEN) in the caudate nucleus (Cd) of morphine dependent rats. Methods The right sciatic nerve was stimulated by train of electrical impulses as noxious stimuli to morphine dependent rats.The electrical discharges of PEN in Cd were recorded with glass microelectrode to observe influences of intracerebroventricular (icv) injection of DA and droperidol on the electrical activities of PEN. Results DA could decrease excitabilities of PEN in Cd of morphine dependent rats. Conclusion Results suggest that the depression of DA on PEN response in Cd of morphine dependent rats might be blocked by droperidol.

Objective To investigate the effects of antisense phosphothioate oligodeoxynucleotides (AS-ODNs) W086 on drug-resistant gene CTX-M expression in Escherichia coli producing extended-spectrum β-lactamases(ESBLs).Methods AS-ODNs liposome was introduced into the purpose bacteria B052.The total colony forming unit(CFU) was counted.The bacteria growth curve was drawn by microplate reader.The inhibition effects of AS-ODNs on the expressions of drug-resistant gene CTX-M were observed by RT-PCR in B052.The minimal inhibitory concentration(MIC)was determined by fluid dilution method.Results significant growth inhibition of cells treated with W086 was observed as compared with those in cells in control treated bacteria.The number of B052 colonies significantly decreased in all W086 treated groups in a concentration dependent manner (P ＜ 0.05),while CFU of B052 was not influenced in simple liposome group,simple W086 group and controlled chain group.The expression of CTX-M was selectively inhibited.Conclusion Efficiently and specificly blocking expression of CTX-M mRNA,AS-ODNs reverses the multiple drug resistance of B052.It indicates that AS-ODNs provides a new viable strategy to reverse antibiotic resistance problem.

The first metatarsophalangeal joint bending plays an important role in the foot movement. However, the existing researches mainly focused on the movement scope of the joint and the clinical treatments of related foot diseases. In order to investigate the effects of the first metatarsophalangeal joint bending on human walking gait stability, the present researchers recruited 6 healthy young men to perform the first metatarsophalangeal joint constraint (FMJC) and barefoot (BF) walking tests. Data of the temporal and spatial parameters, the joint angles of lower limbs, the ground reaction forces (GRF) and utilized coefficients of friction (UCOF) were collected and analyzed. The results showed that, since hip and knee could produce compensation motions, the FMJC had no significant effects on waking gait, but the slip and fall probability increased significantly.
