ABSTRACT

Clinical data of 85 patients with breast abscess during lactation treated in our hospital from January 2014 to October 2017 were retrospectively analyzed.Among 85 cases,30 patients received traditional abscess incision drainage,35 received needle aspiration,and 20 received negative pressure drainage with small incision.The pus culture findings,average hospitalization expenses,average treatment time,pain score,postoperative breast appearance were evaluated.The pus culture found 24 cases of staphylococcus aureus infection in 85 cases (28%),including 40 cases of Methicillin resistant Staphylococcus aureus (47%).The proportion of central abscess (14/20) in patients with small incision drainage was significantly higher than that of patients with needle aspiration treatment (4/35) (P<0.05).The average hospitalization expense of the puncture group was significantly lower than that of other two groups (P<0.01).The average treatment time of abscess incision drainage group was significantly higher than that of other two groups (P<0.01),and the recovery time was all longer 1 month.The score of pain in the abscess incision drainage group was significantly higher than that in other two groups (P<0.01),and all patients had moderate to severe pain.The breast shape satisfaction of abscess incision drainage group was significantly lower than that of other two groups (P<0.01).The analysis indicates that treatment of breast abscess during lactation with needle aspiration and negative pressure drainage has short treatment time,no scars and less pain;and it is suggested that central abscess may be treated early with negative pressure drainage.

ABSTRACT

OBJECTIVE: To explore the relationship between metabolic syndrome( MS) and occupational stress among workers in high altitude area. METHODS: A cross-sectional study was conducted in 940 workers as research subjects who were engaged in petroleum smelting,thermal power generation and financial management et al. in high altitude area. A questionnaire survey was conducted using the Occupational Stress Inventory-Revised for occupational stress, The occupational health examination was performed to measure waist circumference,blood pressure,blood sugar and blood lipids. RESULTS: The abnormal rates in obesity,triglycerides,high-density lipoprotein,blood pressure and fasting blood glucose were 28. 3%,16. 3%,14. 3%,13. 3% and 6. 5%, respectively. The detection rate of MS was 5. 0%( 47/940). The multivariate logistic regression analysis showed that the risk of elevated MS decreased with the increased of occupational stress level( P < 0. 05),and the risk of elevated MS increased with the increased of occupational stress reaction severity( P < 0. 05),after adjusting the confounding factors of gender and labor nature. CONCLUSION: The higher occupational stress reaction of the workers in high altitude area,the higher the risk of MS.

ABSTRACT

Objective@#To investigate the relationship between occupational stress and working ability of workers in a petroleum processing enterprise in a high altitude area.@*Methods@#A total of 728 workers in a petroleum processing enterprise at an altitude of 2850 m were subjected to a survey using Occupational Stress Inventory (OSI) , Work Ability Index (WAI) Scale, Occupational Role Questionnaire (ORQ) , Personal Strain Questionnaire (PSQ) , and Personal Resource Questionnaire (PRQ) from May 2014 to August 2016.@*Results@#Of the 728 workers, 55 (7.6%) had a poor working ability, moderate in 262 (35.9%) , and good in 411 (56.5%). There were significant differences in WAI between the workers with different types of work, sexes, ages, and working years (P<0.05). There was a significant difference in WAI between different occupational stress groups (P<0.05). WAI was negatively correlated with ORQ score and PSQ score (rs=-0.387, P<0.05; rs=-0.467, P<0.05) and positively correlated with PRQ score (rs=0.343, P<0.05). The multiple linear regression analysis showed that high ORQ score and PSQ score were the inhibitory factors for high WAI (B=-0.058; B=-0.082) and high PRQ score was a contributing factor for high WAI (B=0.029) .@*Conclusion@#Occupational stress is an influencing factor for the working ability of workers in the petroleum processing enterprise in the high altitude area. Hypoxia in high altitude area may further reduce the working ability. In order to reduce occupational stress and improve work ability, it should be considered to strengthen skills training, improve the working environment, and pay attention to mental health.

ABSTRACT

BACKGROUND:During ordinary plate fixation, the soft tissues around the fracture of the proximal humerus are nearly stripped to impact blood supply, and moreover, an ordinary steel plate cannot meet with the fixed requirements for severe osteoporosis, large bone defects and comminuted fractures. OBJECTIVE: To observe the functional recovery and complications in middle-aged patients with proximal humeral fractures undergoing stainless steel locking plate implantation. METHODS:From March 2011 to March 2014, 48 patients with proximal humeral fractures were treated in the 306th RESULTS AND CONCLUSION: The 48 patients were folowed up for 6-17 years, and the mean healing time was (15.3±1.2) weeks. At the last folow-up, the Neer scores were excelent in 12 cases, good in 22 cases, fair in 11 cases and poor in 3 cases, with an excelent-good rate of 71%. After internal fixation, there was one case of Hospital of PLA, including 20 males and 28 females, with an average age of 58 years. Of the 48 cases, there were 9 cases of Neer 2 fractures, 26 cases of Neer 3 fractures, and 13 cases of Neer 4 cases, al of which belonged to closed injuries. Al the patients were subject to locking plate implantation for repair of fractures of the proximal humerus, and evaluated based on Neer scores. soft tissue infection, two cases of traumatic arthritis, and no bone ununion and osteomyelitis. These findings suggest that the stainless steel locking plate implantation for repair of fractures of the proximal humerus can achieve a good anatomic reduction under minimaly invasive conditions and produce a stable rehabilitation environment for the soft tissue around the shoulder joint by internal fixation. Hence, the factures can recover faster with less complications. The stainless steel locking plate implantation can obtain good achievements in the repair of proximal humeral fractures of Neer 2, 3 as wel as Neer 4 in young patients with good bone quality.

ABSTRACT

The present study attempted to examine the effects of bile acid pool size on liver regeneration after hepatectomy. The rats were fed on 0.2% cholic acid (CA) or 2% cholestyramine for 7 days to induce a change in the bile acid size, and then a partial hepatectomy (PH) was performed. Rats fed on the normal diet served as the controls. Measurements were made on the rate of liver regeneration, the labeling indices of PCNA, the plasma total bile acids (TBA), and the mRNA expression of cholesterol 7alpha-hydroxylase (CYP7A1), farnesoid X receptor (FXR), and transcription factor c-Jun or c-fos. As compared with the normal and CA groups, the rate of liver regeneration was decreased on the day 3, and 7 after PH; the peak of the labeling indices of PCNA was delayed and the labeling indices were significantly reduced on the day 1; the TBA were also decreased on the day 1; the expression of FXR decreased but that of CYP7A1 increased at any given time; at the 1st, and 3rd h, the expression of c-Jun was declined in the cholestyramine group. The reduction in the bile acid pool size was found to delay the liver regeneration, which may be caused by the down-regulation of FXR and c-Jun expression.

ABSTRACT

Regulation of liver regeneration is a complex pathophysiological process, accompanied by the participation of a large number of cytokines, such as the early stage of IL-6, TNF-α, the proliferation phase of HGF, TGFα, as well as the termination phase of TGFβl, and so on. These factors are coordinated in an orderly adjustment of liver cell proliferation. Enhancing the capacity of liver regeneration after liver resection and transplantation, study on molecular mechanism of liver regeneration is of great significance. This article summarizes liver regenerati after partial hepatectomy and the role of the relevant molecules.
