Background/Aims:
Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy.
Methods:
We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment.
Results:
The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset.
Conclusions
Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.

Large general hospitals currently play an increasingly important role in the diagnosis and treatment for acute critical patients and difficult diseases because of the development of dual referral system and hierarchical diagnosis, as well as the formation of medical treatment alliance. Patients with oral cancers are often associated with systemic diseases, which increases the complexity of the condition. Thus, meeting the demand through the traditional single medical model is difficult. As such, a multidisciplinary team (MDT) model has been proposed and has achieved a good clinical effect. To standardize the application of this model, we organized an event in which relevant experts discussed and formulated a consensus to provide standardized suggestions on the MDT process and the diagnosis and treatment of common systemic diseases as reference for clinical practice.

Our previous study found that plate factor-4 variant (CXCL4L1) was downregulated in the serum of patients with prostate cancer (PCa). The aim of the present study was to investigate the prognostic value of CXCL4L1 in PCa. In total, 213 PCa patients treated with radical prostatectomy were enrolled and peripheral blood samples of all patients were collected. Expression of serum CXCL4L1 in patients with different tumor stages and grades were measured by enzyme-linked immunosorbent assay (ELISA). The Kaplan-Meier method was applied to estimate the progression to castration-resistant prostate cancer (CRPC), metastasis, biochemical recurrence (BCR)-free survival, and overall survival (OS). Prognostic factors for BCR-free survival and OS were determined by univariate and multivariate analyses using the Cox proportional hazards regression model. The expression of CXCL4L1 was significantly lower in PCa patients with advanced pathological tumor stage, high-grade Gleason score, and metastasis. Moreover, downregulation of CXCL4L1 not only strongly correlated with aggressive clinicopathological features, but also predicted tumor progression and unfavorable outcomes. Finally, multivariate Cox regression analyses identified CXCL4L1 as an independent prognostic factor for both BCR-free survival (hazard ratio [HR]: 2.03, 95% confidence interval [CI]: 1.26-3.27; P = 0.004) and OS (HR: 2.26, 95% CI: 1.07-4.79; P = 0.033). In conclusion, our results indicate that CXCL4L1 might serve as a novel and promising prognostic biomarker for patients with PCa and potential therapeutic target in the future.

Objective To evaluate the efficacy and potential renal impairment of one-year combination therapy de novo of adefovir dipivoxil(ADV) and lamivudine(LMV) for decompensated cirrhosis related to HBV. Methods A total of 36 patients with decompensated cirrhosis related to HBV, nobody had nucleos(t)ide analogs(NAs) treatment history, were recruited and were divided into two group(control group and observation group) randomly. A monotherapy of LMV (100 mg per day ) was selected to individuals in control group(n = 18), in contrast, a combination therapy de novo of ADV( 10 mg per day) and LMV( 100 mg per day) was applied to those in observation group( n = 18). Basic approaches including liver protection, symptom-driven intervention, and supporting therapy, were given to all of the individuals. A course of one year was applied to all. Liver function, Child-Pugh score, serum creatinine(sCr) level,virological response(VR) rate, and virological breakthrough rate were observed pro- and post- treatment, differences between the two populations were analysed statistically. Results ( 1 ) The averages of gender,age, HBeAg status, HBV viral load, sCr level, and Child-Pugh score were all compatible in the two groupsat baseline( P ~ 0. 05 for all). (2) At the endpoint of treatment, none of deaths was reported. Comparing with the status before treatment in each group itself, liver function, Child-Pugh score, and viral load were improved statistically (P <0. 01 for all), especially in observed group( P <0. 01 for all variables, vs control group), as for VR rate, result is significant superior to that of control group too(88. 89% vs 66. 67% , P <0.05). (3) Virological breakthrough occurred to none in observed group and three cases (16. 67% ) in control group, all of them were confirmed to be rtM204V variant in the following detection of direct sequencing. (4) Elevated level of sCr didn't arised at the end of treatment in two groups. Conclusion Present study reveals that in populations with decompensated cirrhosis related to HBV, one-year combination therapy de novo of ADV and LMV is superior to monotherapy of LMV, and the renal safety is favorable within one year.

OBJECTIVETo summarize the experience of repair and reconstruction of penile defects as a result of devastating deep burn.
METHODSTwenty-four patients with penile defects in early or late (a half year after wound healed, the same below) stage after burn were involved. Their suspensory ligaments of penis were dissected to lengthen the penis after escharotomy with the necrotic distal part removed. The wounds formed after lengthening were covered with lower abdominal skin flap, scrotal or internal pudendal artery flap. Ten patients underwent surgery within 30 days after burn; the other 14 patients underwent surgery in the late stage. The condition of flaps and complications after surgery were observed. The lengths of penis of patients in flaccid and erection state were measured before surgery and at follow-up period. The sensory function of penile skin, the erectile function of the penis, and sexual intercourse activity of patients were followed up.
RESULTSAll the flaps survived except two, in whom areas of 1.0 cm x 0.5 cm and 1.5 cm x 1.0 cm of necrosis at distal parts were found, and they healed after dressing changes. Patients were followed up for 2 to 5 years. The length of penis in flaccid state was (7.4 +/- 1.6) cm, which was (5.3 +/- 1.4) cm longer than that before surgery (P < 0.01). The length of penis in erection state was (9.7 +/- 1.2) cm. The sensory function of penis recovered gradually about half year after surgery with well preserved erectile function. Except one who did not try to have sexual intercourse again, all the other married patients and their spouses were satisfied or quite satisfied with sexual intercourse activity.
CONCLUSIONSPenis elongation combined with skin flap grafting is a good method for the treatment of penile defects due to devastating deep burn. Suitable length and erectile function of penis can be preserved with this method.

Objective Base on the neighborhood activation model(NAM), to develop the Mandarin monosyllable lexical neighborhood test(M-LNT-monosyllable), which is expected to be useful for evaluating speech perception performance in children with hearing loss. Methods Test items were based on the lexical characteristics of word frequency and neighborhood density which addressed in the neighborhood activation model (NAM). M-LNT -monosyllable consisted of two parts: Lexically "easy" words with high word frequency, which were low phonemically similar to the target word and lexically "hard" words with low word frequency, which were high phonemically similar to the target word. 34 children of 3~5 year old with normal hearing were choosed as subjects to verify easy word and hard word lists. Results 1 979 words for children contained 487 easy words and 419 hard words. Three easy word lists and three hard word lists were developed to estimate the performance of word recognition among normal- hearing children. There were no differences among scores of three easy words lists(P>0.05), and no difference among scores of three hard words lists(P>0.05). But there were significant differences between scores of easy and hard words lists(P<0.01). Conclusion The development of the lexicon was affected by the lexical characteristics. Normal-hearing children with some lexical techniques were affected by the lexical characteristics when they recognized the spoken words, but children with less lexical technique didn't show the same result because the recognition was processed on the phonetic level.

OBJECTIVE:
To determine the effect of different doses of atorvastatin on the serum soluble intercellular adhesion molecules-1 (sICAM-1) in patients undergoing percutaneous coronary intervention (PCI).
METHODS:
The study consisted of 38 patients with unstable angina and 10 patients with old infarction who underwent elected PCI for stenotic lesions of the coronary artery. Patients were randomly assigned to either aggressive group or conventional one. After PCI the patients took atorvastatin 20 mg per day or 10 mg per day. Blood lipid profile was examined before, and 3 months after the PCI. SICAM-1 was examined before the PCI, 48 hours and 3 months after the PCI.
RESULTS:
The total cholesterol and LDL-Cholesterol 3 months after the PCI in the 2 groups were lower than those before the PCI (P<0.01). The aggressive group showed greater reduction in concentrations of TC and LDL-C than the conventional group (P<0.01). The changes in concentrations of HDL-C between pre-PCI and 3 months after the PCI and TG were not obvious (P>0.05). sICAM-1 in the 2 groups 48 hours after the PCI significantly higher than that before the PCI (P<0.01). But sICAM-1 in the 2 groups 3 months after the PCI significantly lower than that before the PCI (P<0.01 or P<0.05). The aggressive group showed greater reduction than the conventional group (P<0.01). TC and LDL-C were positively correlated with sICAM-1(r=0.2413, r=0.2691, all P<0.05).
CONCLUSION
Atorvastatin 20 mg per day reduces TC, LDL-C, and sICAM-1 to a greater extent than atorvastatin 10 mg per day. The effect on sICAM-1 is partly related to reduce lipid profile.
