Subthalamic nucleus (STN) is the main target nucleus for deep brain stimulation (DBS) treatment in patients with Parkinson disease.To implant the electrode on the sensorimotor part of STN individually and accurately,the boundary of STN is required to be clarified clearly on the magnetic resonance imaging (MRI) without geometric distortion.At present,there are three categories of MRI sequences:spin echo sequence including T2-weighted imaging (T2WI),inversion recovery (IR),diffusion tensor imaging (DTI),and fractional anisotropy (FA);magnetization transfer technique including magnetic susceptibility weighted imaging (SWI) and T2-weighted magnitude imaging (T2 * WI);image reconstruction technique such as quantitative susceptibility mapping (QSM).It is found that QSM can provide optimal signal-noise ratio to identify the boundary of STN,T2 * technique comes second.T2WI has high geometric accuracy when the patients wear frame,which is appropriate for direct DBS implantation on STN with frame.

OBJECTIVETo investigate the efficacy and safety of adefovir dipivoxil (ADV, DAIDING) for Chinese chronic hepatitis B patients with lamivudine (LAM) resistance.
METHODSThis study was a multicenter, double-blind clinical trial. 209 chronic hepatitis B patients with LAM resistance were randomly put in an ADV, DAIDING or a LAM group. After 24 and 48-weeks of treatment, serum HBV DNA levels were measured by quantitative PCR and liver function tests; HBV serology and safety assessments were also conducted.
RESULTSThe mean reduction of HBV DNA from baseline at 24 and 48 weeks was significantly greater in the ADV group compared with that in the LAM group (2.40 log10 vs 0.94 log10, P < 0.01; 2.71 log10 vs 1.07 log10, P < 0.01). In the ADV group, the virological response and ALT normalization at 24 and 48 weeks were significantly higher than those in the LAM group. There was no significant difference between the two groups in the portion of HBeAg reduction, HBeAg seroconversion and incidence of adverse events. There was no severe adverse event related to the investigational product, DAIDING, in this trial.
CONCLUSIONDAIDING (ADV) is effective and safe for the treatment of chronic hepatitis B patients with LAM resistance.

INTRODUCTION:
Evidence regarding the efficacy of high-flow nasal cannula (HFNC) oxygenation for preoxygenation and apnoeic oxygenation is conflicting. Our objective is to evaluate whether HFNC oxygenation for preoxygenation and apnoeic oxygenation maintains higher oxygen saturation (SpO2) during rapid sequence intubation (RSI) in ED patients compared to usual care.
METHODS:
This was a multicentre, open-label, randomised controlled trial in adult ED patients requiring RSI. Patients were randomly assigned 1:1 to either intervention (HFNC oxygenation at 60L/min) group or control (non-rebreather mask for preoxygenation and nasal prongs of at least 15L/min oxygen flow for apnoeic oxygenation) group. Primary outcome was lowest SpO2 during the first intubation attempt. Secondary outcomes included incidence of SpO2 falling below 90% and safe apnoea time.
RESULTS:
One hundred and ninety patients were included, with 97 in the intervention and 93 in the control group. Median lowest SpO2 during the first intubation attempt was 100% in both groups. Incidence of SpO2 falling below 90% was lower in the intervention group (15.5%) compared to the control group (22.6%) (adjusted relative risk=0.68, 95% confidence interval [CI] 0.37-1.25). Post hoc quantile regression analysis showed that the first quartile of lowest SpO2 during the first intubation attempt was greater by 5.46% (95% CI 1.48-9.45%, P=0.007) in the intervention group.
CONCLUSION
Use of HFNC for preoxygenation and apnoeic oxygenation, when compared to usual care, did not improve lowest SpO2 during the first intubation attempt but may prolong safe apnoea time.

Repetitive transcranial magnetic stimulation (rTMS) and intermittent theta-burst stimulation (iTBS) are evidenced-based treatments for patients with major depressive disorder (MDD) who fail to respond to standard first-line therapies. However, although various TMS protocols have been proven to be clinically effective, the response rate varies across clinical applications due to the heterogeneity of real-world psychiatric comorbidities, such as generalized anxiety disorder, posttraumatic stress disorder, panic disorder, or substance use disorder, which are often observed in patients with MDD. Therefore, individualized treatment approaches are important to increase treatment response by assigning a given patient to the most optimal TMS treatment protocol based on his or her individual profile. This literature review summarizes different rTMS or TBS protocols that have been applied in researches investigating MDD patients with certain psychiatric comorbidities and discusses biomarkers that may be used to predict rTMS treatment response. Furthermore, we highlight the need for the validation of neuroimaging and electrophysiological biomarkers associated with rTMS treatment responses. Finally, we discuss on which directions future efforts should focus for developing the personalization of the treatment of depression with rTMS or iTBS.

BACKGROUNDReactive oxygen species are thought to contribute to the development of renal damage. The P22phox subunit of nicotinamide adenine dinucleotide phosphate (NAPDH) oxidase, encoded by the cytochrome b245a polypeptide gene, CYBA, plays a key role in superoxide anion production. We investigated the association of CYBA rs7195830 polymorphism with estimated glomerular filtration rate (eGFR) and the role it plays in the pathogenesis of chronic kidney disease (CKD) in a Han Chinese sample.
METHODSThe Gaoyou study enrolled 4473 participants. Serum levels of creatinine were measured and eGFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration equations. The CYBA polymorphisms were genotyped. Then we investigated the association between eGFR and the rs7195830 polymorphism in the recessive model.
RESULTSThe AA genotype of rs7195830 was associated with significantly lower values of eGFR compared with the GG and AG genotypes ((102.76 ± 17.07) ml×min(-1)×1.73 m(-2) vs. (105.08 ± 16.30) ml×min(-1)± 1.73 m(-2)). The association remained significant in the recessive model after adjusting for age, gender, body mass index, smoking, hypertension, diabetes mellitus, uric acid, triglyceride, low density lipoprotein cholesterol and high density lipoprotein cholesterol (β=1.666, P=0.031). The rs7195832 AA genotype was an independent risk factor for CKD: eGFR <60 ml×min(-1)×1.73 m(-2) (odds ratio=3.32; 95% CI=1.21-9.13).
CONCLUSIONThe AA genotype of rs7195830 is independently associated with lower estimated glomerular filtration rate and is significantly associated with CKD.

BACKGROUNDDiabetes mellitus has become epidemic in recent years in China. We investigated the prevalence of hyperglycaemia and inadequate glycaemic control among type 2 diabetic inpatients from ten university teaching hospitals in Guangdong Province, China.
METHODSInadequate glycaemic control in diabetic patients was defined as HbA1c = 6.5%. Therapeutic regimens included no-intervention, lifestyle only, oral antiglycemic agents (OA), insulin plus OA (insulin + OA), or insulin only. Antidiabetic managements included monotherapy, double therapy, triple or quadruple therapy.
RESULTSAmong 493 diabetic inpatients with known history, 75% had HbA1c = 6.5%. Inadequate glucose control rates were more frequently seen in patients on insulin + OA regimen (97%) than on OA regimen (71%) (P < 0.001), and more frequent in patients on combination therapy (81% - 96%) than monotherapy (75%) (P < 0.05). Patients on insulin differed significantly from patients on OA by mean HbA1c, glycemic control rate, diabetes duration, microvascular complications, and BMI (P < 0.01).
CONCLUSIONSThis study showed that glycaemic control of type 2 diabetic patients deteriorated for patients who received insulin and initiation time of insulin was usually delayed. It is up to clinicians to move from the traditional stepwise therapy to a more active and early combination antidiabetic therapy to provide better glucose control.

Background:
and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking.
Methods:
This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance.
Results:
Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal.
Conclusions
The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.
