Objective To determine the expression of human protection of telomeres 1 (hPOT1) and its relationship with Helicobacter pylori (HP) infection in gastric carcinoma.Methods The expressions of hPOT1 protein and hPOT mRNA were detected in 53 gastric carcinoma specimens (observed group) and 20 normal gastric mucosa tissues (control group) by SP immunohistochemical method and in situ hybridization (ISH), respectively.HP infection was examined by Warthin-Starry method in observed group.Results The positive expression rate of hPOT1 protein was 84.91% (45/53) in observed group, higher than that in control group [30.00 % (6/20)] (P < 0.01).The positive expression rate of hPOT1 mRNA was 58.49 % (31/53) in observed group, higher than that in control group [10.00 % (2/20)] (P < 0.05).The positive co-expression rate of hPOT1 protein and mRNA was 56.60 % (30/53), both had positive relationship in gastric carcinoma (r =0.394, P < 0.05).The rate of HP infection in 53 cases of gastric carcinoma was 52.83 % (28/53).The positive expression rates of hPOTI protein and mRNA in observed group with HP infection were significantly higher than those in observed group without HP infection[protein: 96.43 % (27/28) vs 72.00 % (18/25), P <0.05;mRNA: 85.75 % (24/28) vs 28.00 % (7/25), P < 0.01].Conclusions hPOT1 may be associated with occurrence of gastric carcinoma.Combined detection of hPOT1 protein and mRNA can be used for the diagnosis of gastric carcinoma.HP infection may be associated with abnormal expression of hPOT1 in occurrence of gastric carcinoma.

BACKGROUND: Recent study showed that osteocalcin may elevate Insulin secretion and sensitivity, prevent the fat accumulation, play a role in the metablism of glucose and lipid. Undercarboxylated osteocalcin works as the main role. OBJECTIVE: To investigate the effect of different concentrations of glucose on osteoblast undercarboxylated osteocalcin. METHODS: The rib trabeculae were resected and broken, trypsinizated and washed completely by PBS. Bone surface and non-adhesive floating cells in cleaning fluid were observed with inverted microscope. Rib trabeculae was washed by DMEM culture medium once, and cultured in culture bottle. The culture liquid was replaced by new one once a week. The osteoblast was moved from the scledte a week later. The cells were fused monolayer and could be subcultured 4 to 6 weeks later. The active second or third generation cells were inoculated to 6-pore plate forming 5 groups. Osteoblast were stimulated by 5.6 mmol/L., 7.6 mmol/L, 9.6 mmol/L, 12.6 mmol/L, 20.6 mmol/L glucose medium respectively after the 80% cells were fused, the vitamin K_2 was added into the culture liquid until the concentration of it to be 10~(-5) mol/L. Supernatant was collected after half hour culturing, the undercarboxylated osteocalcin level were detected with RIA test kit, and corrected it as the total the undercarboxylated osteccalcin, calculated the carboxylated incomplete osteocalcin rate. RESULTS AND CONCLUSION: The rate of ostecblast carboxylated incomplete osteocalcin was different under different concentration glucose. The rate of 7.6 mmol/L, 9.6 mmol/L, 20.6 mmol/L concentration glucose groups were higher than that of 5.6 mmol/L glucose group [(0.27±0.02)%, (0.29±0.04)%, (0.12±0.02)%, P < 0.05]. It is indicated that osteoblast could sense the change of glucose concentration by regulating the secretion of the undercarboxylated osteocalcin between the concentration of 5.6mmol/L to 9.6mmol/L, while the carboxylated incomplete osteocalcin decreased as the concentration of glucose increased.

Objective:
To evaluate the short-term effect of arthroscopic Endobutton combined with Orthocord suture fixation for tibia eminence fracture of anterior cruciate ligament in adults.
Methods:
The data of 9 adult patients with tibia eminence fracture of anterior cruciate ligament treated with Endobutton combined with Orthocord suture fixation from April 2017 to October 2018 were retrospectively analyzed. The range of motion of knee joint and the stability of knee joint were recorded 3 and 6 months after operation.
Results:
All patients were followed up for 3 and 6 months after operation. CT examination showed fracture reduction and healing 2 months after operation, and magnetic resonance image examination showed good anterior cruciate ligament tension 3 months after operation. The range of motion of knee joint was 0°-130° after 3 and 6 months, and Lanchman test was negative. The Lysholm score was (45.2 ± 6.7) scores, and IKDC score was (55.1 ± 7.3) scores before operation. The Lysholm score was (89.1 ± 7.2) scores, IKDC score was(87.4 ± 6.1) scores, Lysholm score was (95.4 ± 6.5) scores and IKDC score was (93.2 ± 7.8) scores at 6 months after operation.
Conclusions
Endobutton combined with Orthocord suture fixation under arthroscopy has a good short-term effect in the treatment tibia eminence fracture of anterior cruciate ligament in adults.

Objective To investigate the changes in the expression levels of miR-21 and its regulatory proteins in bone tissues of osteoporotic mouse model, and its correlation with bone mineral density. Methods Thirty ovariectomized (ovx) female mice were randomly divided into six groups according to different observation time (0 week, 1 week, 2 weeks, 4 weeks, 6 weeks, and 8 weeks, respectively). Smad7 expression level in the tissues of the distal femur of these mice was immunohistochemically analyzed. Real time PCR was performed at different time points for detecting changes in the mRNA levels of miR-21 and Smad7 target genes in the bone tissue. Dual-energy X-ray absorptiometry (DXA) was used to measure the distal femoral bone density in mice of each group. Results Immunohistochemical study revealed that the expression of Smad7 in the bone tissue of osteoporostic mouse gradually increased over time. Real time PCR analysis showed that the expression of mi R-21 gradually decreased, whereas the expression of Smad7 gradually increased. Over time, the bone density of mice gradually decreased, indicating that miR-21 was positively correlated with bone density, whereas Smad7 was negatively correlated with bone density. Conclusion Bone density of the osteoporotic mice gradually decreases. The expression of miR-21 is positively correlated with bone density, while that of Smad7 is negatively correlated with bone density.

Objective To realize the current situation of prevention and control of catheter-associated urinary tract infection (CAUTI)since the development of healthcare-associated infection(HAI)management in China in the re-cent 30 years.Methods Random cluster sampling was used to select 165 secondary and tertiary hospitals in 13 provinces and cities in China,questionnaires were filled in,the content included time,scope,method,data feed-back,and incidence of CAUTI monitoring.Results Of 165 hospitals,92.12% (152/165)have implemented targe-ted monitoring,the implementation rate in tertiary hospitals was higher than secondary hospitals (98.08% [102/104]vs 81.97%[50/61],χ2 =13.748,P <0.001).Most hospitals (82.24%[125/152])only implemented monito-ring in intensive care units(ICUs)or partial ICUs.HAI management professionals,HAI control doctors and nurses in 69.08%(105/152)of hospitals jointly took responsibility for CAUTI monitoring.95.39% (145/152)of hospitals diagnosed CAUTI by combination of clinical manifestations and laboratory examination results.98.68%(150/152) of hospitals have gradually implemented intervention measures,such as strictly mastering the indications of urinary indwelling catheters,hand hygiene of health care workers,non-frequent change of urinary indwelling catheters,and necessity for daily assessment of catheterization.75.66% (115/152)of hospitals conducted feedback of monitored results to the whole hospital.Incidences of CAUTI in pre-2010,2010,and 2015 were 3.10‰,4.72‰,and 1.89‰respectively.Conclusion In the recent 30 years,monitoring on CAUTI in China has obtained achievement,CAUTI monitoring is gradually standardized and scientific,but the development at all levels of medical institutions is still imbalance,which needs to be improved further.
