The effect of bee pollen of Brassica campestris L. and its alcohol extract on lipid peroxidation was observed in vivo and in vitro.The results showed that the production of lipid peroxides in normal liver hotnogenate of mice and elevation of production of lipid peroxides induced by cysteine and FeSO4 in homogenate were found to be inhibited significantly by in vitro addition of alcohol extract of bee pollen.The elevation of lipid peroxides in serum and liver in adult mice induced by alloxan 75 mg/kg(iv)or by administration of peroxidized corn oil 0.2 ml/mouse was markedly inhibited by oral administration of bee pollen (10 g? kg-1?d-1)for 20 days as compared with respective control groups.The level of lipid peroxide in geriatric mice was also markedly lowered by oral administration of bee pollen (10 g?kg-1?d-1)for 3 months as compared to non-treated geriatric mice.Based on the above in vitro and in vivo experimental results, it may be suggested that bee pollen and its alcohol extract protect tissues against destruction by lipid peroxides.

Objective To investigate the influence of body temperature on the recovery from vecuronium-induced neuromuscular block.Methods Sixty-eight ASA I - II patients (39 male, 29 female) aged 19-69 yr undergoing elective surgery under general anesthesia were randomly divided into 2 groups: group I in which patients' body temperature was maintained at 37 ℃ using warming blanket; group II in which no measures were taken to maintain the patients' body temperature. The patients were premedicated with phenobarbital 2 mg?kg-1 and atropine 0.01 mg? kg-1 intramuscularly. Anesthesia was induced with fentanyl 5 ?g? kg -1, propofol 2 mg? kg-1 and vecuronium 0. 1 mg?kg-1 . After tracheal intubation anesthesia was maintained with inhalation of 0.8%-2.5% isoflurane and propofol infusion at a rate of 2-4 mg ? kg-1? h-1 .Neuromuscular block was monitored using accelograph (Biometer, Denmark) .The changes in TOF and T1 were monitored. T1was maintained at 10% by vecuronium infusion during operation. At the end of operation a bolus of vecuronium 80?g ? kg-1 was given intravenously and T1 was completely depressed. The time for T1 to returned to 5% ,25% and 90% and the time required for T1 to return from 25 % to 75 % were recorded. The total amount of vecuronium given was recorded. Temperature probe was placed in the esophagus ( core temperature) . The room temperature was also recorded. Results The body temperature was lower, the total dose of vecuronium was smaller and the vecuronium-induced neuromuscular block lasted longer in group II as compared with group I . There was close correlation between body temperature and vecuronium-induced neuromuscular block. Conclusions Lower core body temperature could prolong the vecuronium-induced neuromuscular block.

ObjectiveTo observe the curative effect of galvanoiontophoresis combined with ultrashort wave therapy on cervical vertebrae disease-derived arrhythmia.Methods112 patients with cervical vertebrae disease-derived arrhythmia were randomly divided into the treatment group and control group with 56 cases in each group. All patients of two groups were treated with antiarrhythmia drug, Sibelium and traditional Chinese medicine. While, the patients of the treatment group were added with galvanoiontophoresis combined with ultrashort wave therapy to eliminate the aseptic inflammation.ResultsThe cure rate and total effective rate of the treatment group were 51.8% and 94.6%. Those of the control group were 16.1% and 76.8%. The effect of the treatment group was better than that of the control group significantly ( P<0.01).ConclusionThe galvanoiontophoresis combined with ultrashort wave therapy has a better effect on cervical vertebrae disease-derived arrhythmia.

OBJECTIVETo explore the potential effect of Guizhi plus Gegen Decoction (GGD) in improving learning and memory of lipopolysaccharides (LPS) induced neuroinflammatory mice and its possible mechanisms.

METHODSTotally 63 male ICR mice were randomly divided into 5 groups, i.e., the normal control (n = 13), the model group (n = 13), the low dose GGD group (n = 10), the high dose GGD group (n = 14), and the positive control group (n = 13). Mice were intraperitoneally injected with LPS (0.33 mg/kg) to induce Alzheimer's disease (AD) model. Mice in the high and the low dose GGD groups were administered with 12 g/kg or 6 g/kg by gastrogavage for 4 successive weeks. Mice in the control group were intraperitoneally injected with minocycline (50 mg/kg) for 3 days. By the end of treatment LPS were injected 4 h before behavior test each day, and then behavior test was conducted in mice of each group. Effect of GGD on learning and memory of AD mice was observed by using open field test, novel object recognition task, and Morris water maze.

RESULTSOpen field test showed there was no statistical difference in the movement time and the movement distance among all groups (P > 0.05), suggesting that LPS and GGD had no effect on locomotor activities of mice. In novel object recognition test, AD mice spent significantly shorter time to explore novel object after they were induced by LPS (P < 0.05), while for AD mice in the low and high dose GGD groups, their capacities for exploration and memory were significantly improved (P < 0. 05, P < 0.01). Results of Morris water maze showed that AD mice exhibited increased escape latency (P < 0.05) and spent much less time in swimming across the original platform (both P < 0.05). However, AD mice in the low and high dose GGD groups had obvious shortened latency and increased time percentage for swimming (P < 0.05, P < 0.01).

CONCLUSIONGGD possessed certain improvement in learning and memory disorder of LPS induced AD mice.

OBJECTIVETo investigate the characteristics, diagnosis, and treatment of ovotesticular disorder of sex development (OT-DSD).

METHODSWe retrospectively analyzed 2 cases of OT-DSD treated in our hospital. The patients were 19 and 15 years old, respectively, and both received systematic physical examination and examinations of the karyotype, sex hormone, adrenocorticotropic hormone (ACTH), color Doppler ultrasonography, urethrocystoscopy, and human chorionic gonadotropin (HCG) test. Under the laparoscope, we performed surgical gonad exploration, gonadectomy, and vulvar orthopedics. Intraoperative exploration and pathology confirmed true hermaphroditism in both cases, with sex selection as female. One underwent laparoscopic resection of the ovotestis, and the other removal of the testis with the ovarian tissue reserved.

RESULTSThe patients were followed up for 12 months postoperatively, which found no abnormality in either the vulvas or the genital glands.

CONCLUSIONSurgical exploration of the gonad is the only method for the diagnosis of OT-DSD and sex selection is the key to treatment. Laparoscopic surgical exploration of the gonad and vulvar orthopedics are the first treatment options.

This study was aimed to observe the natural history and evolution of cervical spondylotic myelopa-thy , explore development law of the disease incidence in order to improve the understanding of cervical spondylotic myelopathy and provide a theoretical basis for Chinese medicine treatment . Complete clinical data of 80 cervical spondylotic myelopathy cases were collected from March 1998 to July 2007 in special and ex-pert practice of Prof . Shi's out-patient department . Chinese medicine for q i-blood regulation was given in the treatment . Related measuring scales were designed . More than two-month follow-up was given through means of returning visit, telephone calls and letter inquiries. Changes of clinical symptoms, and scores of different types of evaluations were observed . The SPSS software was used in the data analysis of results from measuring scales for the objective evaluation . The results showed that there were statistical differences on the 40-score and JOA total score between initial visiting and first time follow-up ( P < 0 . 05 ) . It suggested that through Chinese medicine qi-blood regulation treatment, the scores on spinal cord function were increased compared with the previous visiting . For patients who continued long-term Chinese medicine q i-blood regulation treat-ment, there were statistical differences on the 40-score and JOA total score between the first-time follow-up and second-time follow-up ( P < 0 . 05 ) . It suggested that through continued long-term Chinese medicine q i-blood regulation treatment , the scores on spinal cord function were increased compared with the previous visit-ing . In this group of patients , there were no statistical differences on the 40-score and JOA total score be-tween the patient's initial visiting , first time follow-up , and the first-time follow-up and second-time follow-up . The scores on spinal cord function suggested that there was no obvious difference on the relieving degree between the first-time follow-up and second-time follow-up . For patients who were unable to continue the Chinese medicine qi-blood regulation treatment, no matter if it was full score on the spinal cord function in the first-time follow-up , there were statistical differences on the 40-score and JOA total score between the first-time and second-time follow-up . It suggested that the disease became worse when patients were unable to continue the Chinese medicine qi-blood regulation treatment. It was concluded that Chinese medicine qi-blood regulation treatment for cervical spondylotic myelopathy has a significant effect in both short-term and long-term treatment with steady effectiveness. Patients who continue the Chinese medicine qi-blood regulation treatment not only can prevent disease recurrence , but also can promote further relieving of disease condition .

OBJECTIVETo explore the correlation between hand and face-mouth, so as to provide nerve reflex basis for the theory "Hegu (LI 4) regulates face and mouth".

METHODSSeven hundred and sixty-three participants who met the inclusive criteria were divided into different age groups. The skin around participants' thenar eminence was gently scraped to be observed whether there was an involuntary movement around the face or mouth, which was palmomental reflex. The results of palmomental reflex were recorded.

RESULTSThe total occurrence rate of palmomental reflex was 46.26%. For those who were 0 to 1 years old, the palmomental reflex was all positive; for those who were 21 to 36 years old, the positive rate was 20.45%, which was the lowest; for those who were 65 to 85 years old, more than half of them were positive. The majority of those who were 0 to 2 years old were bilateral positive palmomental reflex, while the majority of those who were 65 to 85 years old were unilateral positive palmomental reflex.

CONCLUSIONThere is a certain connection between hand and face-mouth. The occurrence rate of palmomental reflex changes from high to low over age increasing, and then changes from low to high with the aging, presenting a "high-low-high" U-shaped curve, which is possible related to the growth and recession of nervous system.
