Objective:To investigate the proper method for treating traumatic chyloperitoneum. Methods: A retrospective analysis was performed on clinical data of 4 cases of traumatic chyloperi- toneum admitted to our hospital in recent 26 years. Results: All 4 cases were cured after conserva- tive treatment. Conclusion: Perdominantly integrated therapy including absolute diet,total parrenter- al nutrition(TPN) and abdominal cavity drainage can be the effective method for the treatment of trau- matic chyloperitoneum.

Objective To investigate the biological effects of nonthermal plasma (NTP) combined with X-ray irradiation on human hepatocellular carcinoma in nude mice.Methods By subcutaneous inoculation, tumor models of human hepatocellular carcinoma HepG2 in nude mice were established, and these mice were divided into control group, NTP treatment group, X-ray irradiation group, combined treatment group.The changes of tumor microenvironment were observed using hematoxylin-eosin (HE) staining.The terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) was used to determine the level of neuronal apoptosis in tumor tissues.The expression of metal matrix proteinase-2 (MMP-2) was detected by immunohistochemical assay.Transmission electron microscope was used to observe cell structure changes.Results The final tumor volumes of control group, NTP treatment group, X-ray irradiation group, combined treatment group were (543.96±108.45), (436.54±65.49), (351.66±56.68), (281.97±35.60)mm3, with a statistically significant difference (F=9.63, P=0.01), and the difference between X-ray radiation group and the combination treatment group was significant (P=0.05).HE staining showed that there was a larger area of necrosis in the combined treatment group compared with the other groups.TUNEL showed that the apoptotic indexes were (0.95±0.13)%, (5.82±0.26)%, (7.53±0.43)%, (11.07±0.35)% respectively, with a statistically significant difference (F=547.76, P=0.00), and the difference between X-ray radiation group and the combination treatment group was statistically significant (P=0.00).The immune scores of each group were 12, 9, 9, 2.Electron microscopic observation showed that there were more apoptotic bodies in the combined treatment group than those in the other groups, accompanied by mitochondrial edema.Conclusion NTP and X-ray irradiation therapy in the treatment of human hepatocellular carcinoma in nude mice model has a synergistic effect.Probably, it can be a new type of treatment in curing cancers.

ObjectiveTo compare the efficacy of laparoscopic appendectomy(LA) and open appendectomy (OA) in treating acute appendicitis.MethodsThe clinical data of eighty patients admitted with acute appendicitis given LA or OA were setrospectively studied and the recovery condition after LA or OA of the two groups were compared.ResultsTime of gastrointestinal functional recovery and hospital day of the LA group were obviously shorter than the OA group[(15.1±7.2)d vs (28.0 ± 11.3)d,(4.2 ±1.9)d vs (5.5 ±3.2)d,all P ＜0.05].The rate of postoperative complications after LA was fewer too.ConclusionLA had advantages of faster function recovery,shorter hospital day and fewer complications,which had higher clinical application value.

Increasing clinical evidence shows that modern lifestyle interrupting circadian rhythm contributes to the prevalence of obesity and diabetes.Recent genetic animal models further support the interaction of circadian rhythms and metabolic state.Circadian clock is not limited to be in central nervous system,and is also present in nearly all cells of the body,which constitute hierarchically circadian systems.The molecular circadian clock is evolved to allow organisms to anticipate and prepared for predictable,daily changes in the environment and regulates cellular and tissue function by driving patterns of gene expression and enzymatic activity.At present,basic science in this field has progressed at an extraordinary pace and is expected to continue unraveling the mechanisms linking circadian clocks to metabolism,which is important for understanding the pathophysiology of metabolic diseases such as obesity and diabetes,and provides a conceptual basis for the prevention and therapeutics of these diseases.

Depression is a common complication after stroke.It is often associated with disability and increased mortality.This article reviews the pathophysiology mechanisms of poststroke depression.

Forty-six anorexia kids were treated with pinching muscles along the spine, tonifying Pitu (spleen-earth), pressing and kneading Zusanli (ST 36) as well as needling Sifeng points (Ex-UE 10) and got recovery in 20 cases, better in 24 cases and failure in 2 cases with the total effective rate of 95.7% .

Objective:To explore the relationship between plasma endothelin and migraine attack. Methods:The plasma endthelin(ET-1) levels were measured by radioimmunoassay in 54 patients with migraine ( classic: 18, common:36 ) and 20 patientsvith tension headache. Results:The plasma ET-1 level in patients with migraine attack was higher than that of normal con-trols or patients with tension headache (P ＜0.01). During intermission, the ET-1 level of patients with classic migraine washigher than that of patients with common migraine (P ＜0.01),and the ET-1 level in male patients was higher than in fe-male ones. Conclusion: The data suggest that there are abnormalities of vascular endothelial cell system in patients with mi-graine. ET-1 may be one of factors causing migraine attack.

Objective To investigate the direct economic loss of nosocomial infection at a tertiary hospital, so as to provide data support for the improvement of hospital infection control. Methods Inpatients discharged in 2013-2015 period were divided into two groups at a 1:1 pairing ratio, having those suffering from nosocomial infection in only one occasion as the infection group, and those without as the non-infection group. The two groups were compared of their differences in days of stay and hospitalization expenses. Results The days of stay of the infection group were significantly longer than the non-infection group, averaging 6 days longer in terms of the median. Compared with the non-infection group, the total hospitalization cost and the differences with sub-categories other than the treatment cost were of significance. The costs over the non-infection group were mostly contributed by drugs, accounting for 50. 39%, while 23. 50% of which were spent on antibiotics. The additional antibiotics costs were mainly incurred by respiratory tract infections during hospitalization, as the costs of antimicrobial agents for the infection group were 27. 34 times that of the non-infection group. The second contributor was surgical site infection, with the cost of antibiotics 7. 63 times that of the non-infection group. Conclusions Hospital infections prolong the days of stay, increase direct economic loss, especially increase the cost of antibiotics. Prevention and control of respiratory system and surgical site infection can effectively reduce the direct economic loss of hospital infection.
