Objective To study the effect of compound nutritional therapy on end-stage liver disease patients with pressure ulcers at Ⅱ phase got from outside the hospital. Methods A total of 101 end-stage liver disease patients with Ⅱ phase pressure ulcers were divided into the observation group (50 cases) and the control group (51 cases) by random digits table method. The control group was treated by conventional diet and drug, and the treatment group was treated by compound nutritional therapy except the conventional diet and drug. The pressure ulcers were assessed daily and the patients were reviewed weekly during treatment. The outcomes of the difference of wound healing and nutritional status improving were compared between the two groups. Results After 14 d treatment, the total of wound healing cure rate was 42.6% (29/68), the total effective rate was 94.1% (64/68) in the observation group, the total of wound healing cure rate was 27.6%(18/65), the total effective rate was 73.8%(48/65) in the control group, and there was significant difference between two groups (χ2=12.726, P=0.005). The healing time was (12.87±2.46) d in the observation group, significantly shorter than that in the control group (17.26±3.51) d, there was significant difference (t=2.760, P=0.005). Conclusions For the end-stage liver disease patients with pressure ulcers at Ⅱ phase got from outside the hospital, compound nutrition therapy can improve the nutritional status, promote the pressure ulcers healing, reduce the economic burden and improve the overall curative effect.

The result of pathological diagnosis was inflammatory granuloma in 1, inflammatory lesion in 1, calcification in 1, hyperplasia of colloid cells in 6, astrocytoma in 1 (WHOⅠ-Ⅱ), astrocytoma in 2 (WHOⅡ), astrocytoma in 1 (WHOⅡ-Ⅲ), mixed oligoastrocytoma in 1 (WHOⅠ-Ⅱ), glioblastoma multiforme in 3 (WHOⅣ), germinoma in 1, brain metastases in 1, diffuse large B-cell lymphoma in 1, intracranial granulomatousarteritis in 1 and negative in 2. There were no serious complications, such as coma, hemiparalysis, infection and intracranial hematoma. Conclusion Stereotactic biopsy is an important method in the diagnose of multiple intracranial lesions. It has the advantages of precise location, less damage, safe performance, and reducing the complication effectively. It is worth promoting.

Objective To investigate the effects of lipopolysaccharide(LPS) on the tryptophan-kynurenine(TRP) metabolic pathway in rat brains and provide new evidence for the relationship between inflammation and depression.Methods Rats in LPS group were given a single dose of 3.5 mg/kg LPS.while the rats in control group were given the same dosage of saline.The dialysis in ventro-hippocampus were collected by microdialysis within 8 hours and then the TRP,KYN and KA were detected by LC-MS/MS.And the expression of indoleamine 2,3-dioxygenase was detected by Western-blot.Results The level of TRP((550.15± 107.96) pmol/L) and KYN ((337.95±62.73) pmol/L) showed a time-dependent increase after administration LPS 4 h compared with the control group(TRP (368.38±59.31) pmol/L,KYN (172.80±43.96) pmol/L),while KA level in the circulation exhibited a trend to decrease,especially at 7 h ((3.47±0.62) pmol/L,P＜0.05).The ratio of KYN/TRP significantly increased at about 5 h (0.69±0.11,P＜ 0.05),and an ratio of KA/KYN (0.02±0.00) was dramatically decreased after administering LPS 4 h compared with the control group (0.05±0.01)(P＜0.05).Most of the analytes showed more dramatic changes around 4 h to 8 h.LPS group(1.48±0.37) increased the protein expression of indoleamine 2,3-dioxygenase compared with the control group(1.00±0.24) (P＜0.01).Conclusions LPS may cause tryptophan metabolic abnormalities and accelerate the way of kynurenine metabolism,leading to decreased the kynurenic acid status.

Objective:To conduct a survey on the difference in medical staff remuneration level and satisfaction within the eastern, central and western township health centers, explore the influencing factors on remuneration satis-faction, and put forward some suggestions. Methods:909 medical staff and 104 township health centers from 9 coun-ties in the eastern, central and western regions were investigated. The Descriptive, ANOVA and Hierarchical Linear Model ( HLM) methods were used to analyze the survey results. Results:Average annual medical staff remuneration was 28 324 Yuan in 2011 and the remuneration satisfaction was 2. 77 in five-point scale. The difference between the remuneration level (F=140. 16,P<0. 001) and remuneration satisfaction (F=240. 84,P<0. 001) among three re-gions was statistically significant. The HLM analysis indicated that the working time, workload per day in individual level and whether by practicing the policy of separation between revenue and expenditure, the number of average monthly discharged patients and the fiscal appropriation income in the township health centers level affected the remu-neration satisfaction. Conclusions:The medical staff remuneration level and satisfaction in the township health centers were low, both having a great regional difference. Therefore, the improvement of the medical personnel remuneration satisfaction is obtained through improving the revenue and expenditure, and the performance-based pay system.

Objective To compare using the transabdominal route versus the transoral route in establishing naso-biliary drainage in laparoscopic surgery.Methods The combined use of laparoscopy with choledochoscopy and duodenoscopy to establish naso-biliary drainage was carried out in 204 patients with gallbladder and common bile duct calculi.In 162 patients,the naso-biliary drainage was established transabdominally and in 42 patients it was established transorally.The success and the complication rates in the two groups were compared.Results Of 162 patients using the transabdominal route,4 patients failed.There were 6 patients (3.7％) who had no output from the nasobiliary drain.There were 3 patients (1.8％) who had only intestinal juice outflow from the nasobiliary drain.Primary closure failed in 3 patients (1.8％),all resulting in bile leak.Pancreatitis occurred in 2 patients (1.2％) after the operation.There was 1 patient (0.6％) whose nasobiliary drain was wrongly ligated.Of 42 patients with nasobiliary drainage using the transoral route,6 patients failed.There was 1 patient (2.4％) who had no output from the nasobiliary drain.There was 1 patient (2.4％) who had intestinal juice output from the nasobiliary drain.Primary closure failed in 1 patient (2.4％) with resultant bile leakage.Pancreatitis occurred in 4 patients (9.5％) after the operation.The success rate of establishing a nasobiliary drainage in the transabdominal group was significantly higher than that in the transoral group,but the complications were less.Conclusions Nasobiliary drainage established through the transabdominal route in laparoscopy surgery for patients with gallbladder and common bile duct calculi was technically easier and had a high success rate.It had less complications.

A simple,fast and highly sensitive fluorescence analysis method for detection of mercury ion was developed based on N-methyl-mesoporphyrin IX (NMM)/G-quadruplex DNA system and specific T-Hg-T mismatches.In this strategy,a large number of thymine was introduced into guanine-rich oigonucleotides which could form G-quadruplex.In the presence of Hg2+,guanine-rich oigonucleotides and complementary strand could form double-stranded DNA molecule by specific T-Hg-T mismatch pair,leading to destruction of G-quadruplex DNA structure.In the absence of Hg2+,guanine-rich oigonucleotides spontaneously formed G-quadruplex DNA structure that could bound NMM to generate intense fluorescence.Based on the above facts,a sensitive fluorescence biosensor for determination of Hg2+ was fabricated.And the optimal conditions for Hg2+ determination were as follows:buffer solution pH of 6.7,20 mmol/L KCl and 2.5 μmol/L NMM in buffer and incubation for 2 h.Under the optimal conditions,the fluorescence intensity signal change (F0-F) and the Hg2+ concentration exhibited a linear correlation within 50 nmol/L to 1000 nmol/L range with a low detection limit of 22.8 nmol/L (3σ).The biosensor exhibited good selectivity toward common metal ions.The developed method was successfully employed to detect Hg2+ in tap water with recovery of 106.1％-107.8％.
