1.Minimally invasive and precise treatment of malignant tumor
Chinese Journal of Clinical Oncology 2016;43(11):452-456
The treatment of malignant tumor is one of the world's worst medical problem and is thus a research hotspot. The occur-rence of tumor development follows the molecule→cell→tissue→organ process. In theory, treatment can be achieved at any stage of tumor-growth by inhibition. Minimally invasive technology for treating tumor embodies the following direction of tumor treat-ment:minimally invasive, precise, and efficient. With endoscopy or imaging as a guide, the purpose of minimally invasive therapy is to have a small wound and to control tumor maximally at the tissue and organ level;thus, this therapy mode is the best and most pre-cise. This kind of technology has a good application prospect, even in the case of distant metastasis, and can be used to relieve the symptoms and improving the quality of survival by treating lesions affecting important organ functions. Minimally invasive therapy is a great challenge following the direction of modern medicine. With the development of medical science and technology, the important role of minimally invasive therapy in future tumor therapy is foreseen.

Background and Objectives: Anticoagulation clinics are widely used for anticoagulation management
in many countries, but have only recently began to gain acceptance in Taiwan. Our service model is
a physician-managed outpatient clinic collaborating with clinical pharmacist and nurse. This study
aimed to evaluate the adequacy of anticoagulation and rates of warfarin-related complications before
and after referral to our collaborative anticoagulation clinic (CAC). Methods: Stroke patients taking
warfarin from the neurology department were identifi ed and referred to the CAC during the 12-month
period from February 2009 to January 2010. Quality markers include percentage of international
normalized ratio (INR) values in the therapeutic range, frequency of INR monitoring, and frequency
of follow-up visits and the mean interval of next INR monitoring after non-therapeutic INRs were
compared one year before and after management in the CAC. Using studied patients as self-control,
they were included in the analysis if patients had at least 3 months follow-up or 3 INR values both
before and after referral. Results: A total of 44 stroke patients were included: mean age of 75.0 ± 9.7
years, with a CHADS2
score of 3.71 ± 0.69. The adequacy of anticoagulation was signifi cantly greater
during CAC care compared with the period before referral; the percentage of INR within expanded
therapeutic range was 60.9% versus 53.7%, respectively (p=0.049). Reduction in sub-therapeutic INR
values from 31.8% to 24.2% (p=0.023) contributed mostly to the improved quality of care. The time
interval of next INR monitoring after non-therapeutic INRs ( 4.0 or 1.5) was also signifi cantly
shorter. However, there was no signifi cant difference in the rates of thromboembolic and hemorrhagic
events which may be attributed to a small sample size.
Conclusion: Based on results of our study, a CAC may be the optimal structure for anticoagulation
management service in the future.

Objective:
The study investigated cognitive performance and brain function between treatment-resistant depression (TRD) and non- TRD patients to find potential neurobiological markers associated with refractoriness in depression patients.
Methods:
Fourteen TRD patients, 26 non-TRD patients and 23 healthy controls (HC) were included in the present study. The neural function of prefrontal cortex (PFC) and cognitive performance among the three group were examined using near-infrared spectroscopy (NIRS) during verbal fluency task (VFT).
Results:
Both TRD and non-TRD groups exhibited significantly worse VFT performance and lower activation of oxygenated hemoglobin (oxy-Hb) changes in the bilateral dorsolateral PFC (DLPFC) compared to the HC group. Within the TRD and non-TRD groups, VFT performance was no significant difference, but activation of oxy-Hb changes in dorsomedial PFC (DMPFC) in TRD patients was significantly lower than non-TRD patients. In addition, activation of oxy-Hb changes in right DLPFC were negatively correlated with the severity of depressive symptoms in depression patients.
Conclusion
Both TRD patients and non-TRD patients exhibited lower oxy-Hb activation in DLPFC. TRD patients exhibit lower oxy- Hb activation in DMPFC than non-TRD patients. fNIRS maybe a useful tool for predict depressive patients with or without treatment resistant.

BACKGROUND:The mouse double minute 2 (MDM2) is a negative regulator of the p53 tumor suppressor protein.Overexpression of MDM2 is associated with poor survival and is a useful predictive factor for poor prognosisin various cancers in human. Studies revealed a genetic polymorphism located in intron 1 of the MDM2gene, MDM2-SNP309, (a change from T to G) is main functional polymorphism and important to developtumors. However, inconsistent associations between the MDM2-SNP309 and the risk or early onset ageof human different cancers have been reported worldwide. These conflicting results may have dependedon different patient subgroups and ethnicities studies. We studied the association of the MDM2-SNP309polymorphism andbladder cancer in Mongolian patients for the first time.OBJECTIVE:To investigate association between MDM2-SNP309 and the risk bladder cancer or early onset age of thecancer in Mongolian patients.MATERIALS AND METHODS:We genotyped MDM2-SNP309 in 44 patients with bladder cancer and 44 age and gender matched healthycontrols among Mongolian people.Genomic DNA was extracted from whole blood samples by the standardmethod of Qiagen mini blood DNA extraction kit (Qiagen Inc., Valencia, CA) and PCR amplification wasperformed using 100 ng genomic DNA template according to manufacturer’s protocol (Invitrogen, Carlsbad,CA). MDM2 SNP309 genotyping was carried out by restriction fragment length polymorphism assay.RESULTS: The allele frequencies of MDM2 SNP309 in the 44 bladder cancer patients were wild-type (T/T) 27.3%,homozygous (G/G) 34.1% and heterozygous (T/G) 38.6% whereas in the control cases were wild-type(T/T) 29.5%, homozygous (G/G) 20.5% and heterozygous (T/G) 50.0%. The proportion of homozygous(G/G) genotype was higher for bladder cancer cases than for healthy controls. Compared to the low-risk(wild type) genotype, an increased risk association with bladder cancer was shown for the GG genotype(OR=2.0, 95% CI=1.03-1.84). There is also a significant difference in median age onset of bladder cancerbetween GG low and high risk genotypes T/T and T/G (p=0,003)( p=0.0001), respectively (Figure2).CONCLUTION: The current sample data suggests that MDM2 SNP309 GG genotype may be associated withthe risk of bladder cancer as well as an earlier age onset in Mongolian patients with bladder cancer.
