Hepatitis B virus (HBV) infection is closely associated with the adverse events such as liver cirrhosis, liver cancer, and liver failure and remains a serious threat to human health. Pegylated interferon is an indispensable drug for the treatment of chronic hepatitis B (CHB), and interferon-stimulated genes are associated with a variety of viruses, but few studies have mentioned their association with hepatitis B and their predictive effect after the treatment of hepatitis B with interferon. This article introduces the predictive factors for interferon treatment of CHB and summarizes the association of interferon-stimulated genes with hepatitis B and their predictive effect, so as to provide a reference for clinical work and basic research.

Objective To analyze the anatomical characteristics of the upper airway in Pierre Robin sequence pediatric patients with difficult laryngoscopy using the computed tomography-based three-dimensional reconstruction.Methods Fifty pediatric patients of both sexes with Pierre Robin sequence,aged 10-101 days,weighing 2.0-6.3 kg,of American Society of Anesthesiologists physical status Ⅲ,scheduled for elective mandibular distraction osteogenesis under general anesthesia,were enrolled in this study.Cone beam CT scan was performed to obtain upper airway anatomy information during the natural sleep before operation.Images were imported into medical engineering software MIMICS 17.0 to reconstruct the three-dimensional images of the oral and maxillofacial bones and airways.The related anatomical parameters were measured,including the distance between the alveolar ridge of the upper central incisor and root of the epiglottis (D1),distance between the root of the epiglottis and midpoint of glottis (D2),distance between the bilateral lower edge of the mandible and midpoint of glottis (D3),distance between the alveolar ridge of the lower central incisor and the lower edge of the mandible (D4),length of the mandibular ramus (D5),length of the mandible body (D6),and length of the total mandible (D7),angle between lines D1 and D2 (angle 1),the angle between line D2 and the alveolar ridge of the upper central incisor to the midpoint of glottis (angle 2),the angle between lines D3 and D4 (angle 3),the angle of the point of the upper central incisor alveolar ridge to the trailing edge of the hard palate and then to the root of epiglottis (angle 4),the angle of bilateral mandible (angle 5),the angle of the point of gnathion to the two gonions (angle 6),the airway cross-sectional area at the tip of epiglottis,volume of oral cavity,volume of velopharyngeal cavity,and volume of glossopharyngeal cavity.Fiberoptic bronchoscope-guided endotracheal intubation was performed under topical anesthesia with lidocaine.Propofol,sufentanil and cis-atracurium were intravenously injected to induce anesthesia after successful intubation,and then the pediatric patients were sent to the operating room.Anesthesia was maintained by inhalation of sevoflurane.The exposure of glottis was observed with a laryngoscope.Pediatric patients were divided into difficult laryngoscopy group (group A) and non-difficult laryngoscopy group (group B) according to whether they presented with difficult laryngoscopy (Cormack-Lehane classification Ⅲ or Ⅳ).Results Compared with group B,the airway cross-sectional area at the tip of epiglottis and in the volume of velopharyngeal cavity were decreased (P＜0.05),and no significant change was found in D1,D2,D3,D4,D5,D6,D7,angle 1,angle 2,angle 3,angle 4,angle 5,angle 6,volume of oral cavity or volume of glossopharyngeal cavity in group A (P＞0.05).Conclusion The three-dimensional CT images of the upper airway show characteristic changes in Pierre Robin sequence pediatric patients with difficult laryngoscopy,and the main manifestations are the decrease in the airway section area and in the volume of the palatopharyngeal cavity at the tip of the epiglottis.

OBJECTIVE: To investigate the efficacy and safety of the bladder training in male patients before urinary catheter removal after mid-low rectal cancer surgery. METHODS: This was a prospective, open, randomized controlled study. INCLUSION CRITERIA: male patients; pathologically diagnosed as mid-low rectal adenocarcinoma; distance from tumor lower edge to anal margin ≤10 cm; standard radical surgery for rectal cancer, including intestinal resection and regional lymph node dissection. EXCLUSION CRITERIA: previous history of benign prostatic hyperplasia or history of prostate surgery; bladder dysfunction such as dysuria and urinary retention before surgery; local resection of rectal tumor or extended resection. According to the above criteria, 92 patients who underwent colorectal surgery at the Union Hospital of Fujian Medical University from June to December 2016 were prospectively included. The patients were randomly divided into bladder training group (n=43) and bladder non-training group (n=49) according to the random number table method. The study was approved by the Ethics Committee of the Union Hospital of Fujian Medical University (ethical approval number: 2016KY005) and registered with the China Clinical Trial Registration Center (ChiCTR) (registration No.ChiCTR-IOR-16007995). The implementation of patient's treatment measures, the data collection and analysis were based on the three-blind principle, using envelopes for distribution concealment. In the bladder training group, bladder training was routinely performed from the first day after operation to catheter removal, and in bladder non-training group the catheter was kept open till its removal. The catheter was removed in the early morning at the 5th day after surgery, and the spontaneous urine output was recorded and the residual urine volume of the bladder was measured after the first urination. The international prostate symptom score (IPSS) was applied to evaluate the patient's urinary function before and after surgery. RESULTS: The age of whole group was (58.6±10.9) years old, the body mass index was (22.4±2.7) kg/m , and the distance from tumor lower edge to anal margin was (6.5±1.9) cm. The baseline data, such as age, body mass index, distance from tumor lower edge to anal margin, preoperative IPSS score, preoperative bladder residual urine volume, neoadjuvant radiotherapy and chemotherapy, preventive ileostomy and surgical procedure were not significantly different between two groups (all P>0.05). There was no significant difference in IPSS scores evaluated at the second day (3.6±4.0 vs. 3.5±3.4, t=0.128, P=0.899) and one month (3.7±2.9 vs. 3.0±3.1, t=1.113, P=0.269) after catheter removal between the bladder training group and bladder non-training group. No significant difference in the postoperative residual urine volume of bladder (media 44 ml vs. 24 ml, Z=-1.466, P=0.143), the first spontaneous urination volume (median 200 ml vs. 150 ml, Z=-1.228, P=0.219) after catheter removal, and postoperative hospital stay [(8.2±4.5) days vs. (9.1±5.5) days, t=-0.805, P=0.423] was found. Urinary infection rate was 20.9%(9/43) in the training group, which was even higher than 8.2%(4/49) in the non-training group, but the difference was not significant(χ²=3.077, P=0.079). No patient needed re-catheterization in either group. CONCLUSIONS The routine bladder training after mid-low rectal cancer surgery does not improve the urinary function, and can not reduce the residual urine volume of bladder after catheter removal. This routine clinical practice is not helpful for the bladder function recovery after rectal cancer surgery.

Twenty-six eyes which appeared rejection after allograft penetrating keratoplasty between April 2003 and April 2004 in Shandong Shi'erming Eye Hospital were collected, including 16 males and 10 females, 9 cases were repeated relapsing viral keratitis, 8 cases were traumatic posterior corneal leucoma, 5 cases were corneal decompensation caused by various intraocular surgery, 2 cases were congenital leucoma, and 2 cases had other symptom. The rejection occurred at 2 month to 2.5 years after operation. Among them 19 cases were transferred to our hospital and asked adding traditional Chinese therapy because western medicine was ineffective in other hospital. All cases were received local treatment with hormone and non-steroidal anti-inflammatory eyedrop, some cases applied systemic administration with glucocorticoid, mainly based on eye black immunosuppression decoction, potion daily, twice per day, the average time of medication was 11-42 days. Clinical symptoms were served as observation indexes, results showed that the total effective rate of the 26 cases were 100%. The bulbar conjunctiva hyperemia and edema was reduced, corneal opacity became light, and rejection was complete response in 9 cases, 5 of 19 cases which were transferred to our hospital were exempted from operation, and the average vision was improved three lines. It was found that purging liver and eliminating dampness compound Chinese medicine can rapidly reduce anterior chamber's inflammatory response and backoff corneal neovascularization in clinical practice.

OBJECTIVETo investigate the effect of lovastatin on proliferation and extracellular matrix secretion of hepatic stellate cells in vitro.

METHODSRat hepatic stellate cells were incubated with different concentration of lovastatin and geranyl geranypyrophosphate. Cell proliferation was assessed by MTT colorimetric assay. Cell cycle was analysed by flow cytometry. Type IV collagen and laminin were determined by ELISA, and c-jun and c-fos expression by immunocytochemistry and computer video text analysis system.

RESULTSAddition of 0.1 to 50 micromol/L lovastatin into culture medium had no toxicity to hepatic stellate cells, but could significantly inhibit hepatic stellate cell proliferation and provoke G0/G1 phase arrest in dose-dependent manner, and could also markedly inhibit the c-jun and c-fos expression and type IV collagen and laminin secretion, which could partly be antagonized by geranyl geranypyrophosphate.

CONCLUSIONSLovastatin can significantly inhibit hepatic stellate cell proliferation and type IV collagen and laminin secretion, which might be partly related to its inhibitory effect on geranyl geranypyrophosphate formation.

Objective To investigate the effect of recombinant human tumor necrosis factor (rhTNF) on telomerase activity in hepatoma cell line HepG2 cells and HepG1 6 cells. Methods TRAP ELISA method was used to determine the telomerase activity in HepG2 and HepG1 6 cells which were treated by different concentrations of rhTNF; plasmid which had been inserted 800 bp of the hTERT promoter was transiently transfected into HepG2 cells by Lipofect, and different concentrations of rhTNF were added into culture media 2 hours later, then the activity of the hTERT promoter was tested 48 hours after transfection. Results The telomerase activity of HepG2 was suppressed by rhTNF in a dose dependent manner. The expression of hTERT promoter was inhibited linearly with the dose of rhTNF within the range of 10～1 000 IU/ml. Conclusions Above results suggest that the anti tumor activity of rhTNF may attribute to its inhibitory effect on hTERT promoter expression.
