OBJECTIVE:To investigate the utilization of antineoplastic drugs in our hospital. METHODS:A retrospective analysis was conducted on antineoplastics used during 2005-2007 in our hospital in respect of the consumption sum,DDDs and average daily cost etc. RESULTS:Over the 3 years,the proportion of antineoplastics showed a year-on-year increase in consumption sum,with the antitumor plant amedica topping the consumption sum list and Tamoxifen topping the DDDs list for three years. Domestic drugs,injections and drugs on the RDL (reimbursable drugs list for basic medical insurance) showed high DDDs in our hospital. CONCLUSION:The consumption of antineoplastics is basically rational in our hospital,yet its management remains to be further tightened.

BACKGROUND:Previous studies have found that cholecystokinin octapeptide (CCK-8) can promote the regeneration after sciatic nerve injury in rats, but the exact mechanism remains unclear.
OBJECTIVE:To screen effective indicators and analyze the mechanism of CCK-8 promoting sciatic nerve regeneration from the perspective of nerve growth factor and nerve regeneration microenvironment.
METHODS:Healthy Sprague-Dawley rats, for the preparation of unilateral sciatic nerve transection injury model, were randomly divided into two groups. In the CCK-8 group, the animal model received intraperitoneal injection of CCK-8 (8 nmol/kg) for consecutive 7 days, while the control group was injected with equal volume of normal saline. The nerve growth factor expression, inducible nitric oxide synthase in the spinal cord, serum superoxide dismutase activity and malondialdehyde concentration, as wel as apoptotic cel s in spinal cord were al detected.
RESULTS AND CONCLUSION:In the CCK-8 group, nerve growth factor expression was higher than that in the control group (P<0.01), while inducible nitric oxide synthase and the number of apoptotic cel s were lower (P<0.01), serum superoxide dismutase activity was higher but malondialdehyde concentrations was lower (P<0.01, 0.05). The mechanisms of CCK-8 promoting sciatic nerve regeneration include protecting neurons, anti-apoptosis, inhibiting inflammatory response, anti-NO and anti-oxidation, reducing malondialdehyde, and al eviating free radical damage, as wel as stimulating nerve growth factor expression and release.

BACKGROUND:To repair and reconstruct the joint capsule and surrounding ligaments is one of effective methods against displacement and dislocation after total hip arthroplasty. In recent years, anterolateral total hip arthroplasty has been widely used, but little is reported on the anatomic features of the anterolateral hip joint capsule and iliofemoral ligament. OBJECTIVE:To investigate the anatomic features of the anterolateral hip joint capsule and iliofemoral ligaments, thereby providing anatomic evidence for selecting and optimizing the approach for total hip arthroplasty and for clinical practice. METHODS:Thirty adult cadaver hips fixed with formalin were used for this study. The anterolateral hip joint capsule and the iliofemoral ligaments were dissected and anterolateral hip joint capsules were divided into three sections and nine parts. The average thickness of each part and the average height and width of each section were measured. The anterolateral hip joint capsule was observed by its beginning and ending, course, branch and histological features. RESULTS AND CONCLUSION:The anterolateral hip joint capsule was tightly connected with the iliofemoral ligaments to form a complex. The thickness of the capsule was varied. The thinnest parts of the complex were BI and BII. In addition, the average height and width of each section were different. The joint capsule originating from the anterior inferior iliac spine and acetabulum was divided into three branches and fixed on the intertrochanteric line. Understanding of the anterolateral hip joint capsule and iliofemoral ligaments may make for the approach selection, design and optimization of total hip arthroplasty.

BACKGROUND:Interleukin-12 (IL-12) may function as an immune regulator in the pathogenesis of osteoarticular tuberculosis. OBJECTIVE:To explore the association of single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C with susceptibility to osteoarticular tuberculosis and serum interleukin-12 levels in Guangxi Zhuang population. METHODS:The single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C polymorphisms were detected by polymerase chain reaction-single base extension technique and direct DNA sequencing in 150 patients with osteoarticular tuberculosis (disease group) and 165 healthy individuals (control group) in Guangxi Zhuang population. The genotype and al ele frequencies of IL-12 and the relationship of genotypes to the susceptibility to osteoarticular tuberculosis were analyzed. In addition, the association of genotypes of single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C with serum IL-12 levels were analyzed. RESULTS AND CONCLUSION:There was no significant difference in the genotype and al ele frequencies of IL-12A rs568408 G/A and IL-12B rs3212227 A/C between the disease group and the control group (P>0.05). Moreover, there was no difference in four haplotypes of IL-12 gene between the disease group and the control group (P>0.05). Serum IL-12 levels in subjects with osteoarticular tuberculosis carrying the variant rs568408 GA/AA genotypes and wild-type rs568408 GG genotypes were similar (P>0.05). Similarly, there was no significant difference in serum IL-12 levels between subjects with osteoarticular tuberculosis carrying the variant rs3212227 AC/CC genotypes and wild-type rs3212227 AA genotypes (P>0.05). These findings suggest that the single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C polymorphisms are not associated with susceptibility to osteoarticular tuberculosis in Guangxi Zhuang population.

Objective To survey the current situation and explore the association between empathic ability and job adjustment disorder of pediatric nurses. Methods The Jefferson scale of empathy health professionals and job adjustment disorder scale were used for the survey among 189 pediatric nurses. Pearson correlation analysis was used to explore the association between empathic ability and job adjustment disorder of pediatric nurses. Results The total score of empathic ability of pediatric nurses was (76.32 ±5.03), the score of their job adjustment disorder was (23.69 ±6.03). Their empathic ability and its dimensions were significantly negatively related with job adjustment disorder (P ＜0.01). Conclusions The empathic ability of pediatric nurses was at a medium to low level, job adjustment disorder was at a medium to high level. The higher level of pediatric nurses' empathic ability, the lower level of job adjustment disorder is. Hospital staff should take measures to improve pediatric nurses' empathic ability, and the pediatric nurses themselves should also actively cultivate their own perception, and improve the empathic ability so as to better acclimatize themselves to pediatric nursing job and reduce the degree of job adjustment disorder.

Objective:To investigate the level of rumination and its influential factors among Chinese psychiatry nurses who go through work place violence.Methods:In this study, 150 psychiatry nurses were recruited from Affiliated Brain Hospital of Guangzhou Medical University (specialize in psychiatry), via the combination of convenient sampling and snowball sampling. Chinese Event-related Rumination Inventory (C-ERRI) was applied in the survey.Results:The total score of C-ERRI was (22.11±9.62) points, and the scores of intrusive rumination subscale and deliberate rumination subscale were (12.99±5.58) and (9.12±6.01) points, respectively. Multiple Linear Regression Analysis show that assault frequency in recent year ( B=-3.195, P<0.01) and whether got injury in the recent assault ( B=8.591, P<0.01) were predictors of deliberate rumination, which account for 26.8% variance of the equation. Gender (male) ( B=-2.415, P<0.01), Injury frequency in recent year ( B=2.864, P<0.01) and whether got injury in the recent assault ( B=8.949, P<0.01) were predictors of intrusive rumination. They account for 36.0% variance of the equation. Conclusion:In this study, the level of rumination among Chinese psychiatry nurses was low. Their rumination style was deliberate rumination.

Objective To evaluate the effectiveness of Lingshao-Zaoren granule in the treatment of female overactive bladder. Methods A total of 60 female OAB patients who met the inclusion criteria were randomly divided into 2 groups, 30 cases in each group. The control group recieved the Tolterodine Tartrate Sustained Release Tablets and the Lingshao-Zaoren granule placebo, and the treatment group used the Tolterodine Tartrate Sustained Release Tablets and the true Lingshao-Zaoren granule treatment. Both groups were treated for 4 weeks. Overactive bladder symptom scale (OABSS) was used to determine the severity of OAB.Results After treatment 14,28 d,OABSS scores of the treatment group(5.3 ± 2.3,1.4 ± 1.2 vs.8.4 ± 2.4,F=137.209),and control group(7.8 ± 1.9,6.8 ± 1.4 vs.8.6 ± 2.6,F=8.927),were significantly lower than the baseline of each group respectively (P<0.01). Besides, OABSS scores of the treatment group after 14 and 28 d were significantly lower than the control group (t=4.668, 15.678, P<0.01). The pain scores (5.9 ± 1.9, 2.7 ± 1.1 vs.9.5 ±2.3,F=108.819)of treatment group at 14 and 28 d were significantly lower than the baseline(P<0.01);and the pain scores of treatment group at 14 and 28 d were significantly lower than the control group (t=6.342, 14.812,P<0.01).The lower abdomen discomfort scores at 14,28 d in treatment group(1.9 ± 1.4,1.1 ± 1.0 vs. 3.3 ±1.1,F=28.762),and control group(2.7 ±1.0,2.4 ±0.8 vs.3.4 ±1.2,F=12.103)were significantly lower than the baseline of each group (P<0.01); and the abdominal discomfort scores of treatment group at 14, 28 d were significantly lower than the control group (t=2.521, 5.041, P<0.05 or P<0.01). Conclusions The Lingshao-Zaoren granule could decrease OABSS score,pain score,abdominal discomfort symptoms,improve clinical symptoms of the female patients with OAB.

Near-infrared spectroscopy is a device used to determine whether traumatic intracranial hemorrhage has occurred and is primarily used for screening in emergency situations. In this study we examined the applicability of this equipment in postmortem inspection. This study included 124 autopsy cases and 59 postmortem inspection cases performed in the National Forensic Service from July 2017 to October 2018. We carried out the test using Infrascanner Model 2000 (Infrascan Inc.). Autopsy cases were divided into four groups (epidural hemorrhage or subdural hemorrhage group, traumatic subarachnoid hemorrhage or cerebral contusion group, nontraumatic intracerebral hemorrhage group, and control group) and analyzed. There was no difference in the test results according to the presence and type of intracranial hemorrhage. The possibility that variables related to postmortem change affected the test results was considered. In conclusion, this study confirmed that near-infrared spectroscopy is not suitable for the detection of traumatic intracranial hemorrhage in postmortem inspection.

The expression of histone lysine-specific demethylase 1 (LSD1) in colorectal cancer cells is increased, and LSD1 is closely related to its occurrence, development, proliferation, invasion and metastasis. LSD1 is a demethylase whose function depends on flavin adenine dinucleoside. It can specifically catalyze the demethylation reaction of histone lysine, and regulate the expression of target genes by reaction of demethyl and dimethyl (H3K4me, H3K4me2, H3K9me, and H3K9me2) at the 4th and 9th positions of lysine H3. Targeted inhibition of LSD1 has been proved to be able to exert significant anti-tumor effect, but since the tumors involve multiple centers and factors, later studies have found that single inhibition of LSD1 cannot completely and effectively kill tumor cells. Moreover, the specificity of the LSD1 catalytic substrate depends to a large extent on the synergistic factors that bind to it and form complexes. The double-target inhibitors based on LSD1 shows more remarkable effect in tumor inhibition. Therefore, finding the combined synergistic factors of LSD1 may provide the basis for the research of multi-target inhibitors.
