OBJECTIVETo compare clinical efficacy of Zero-profile implant for anterior cervical discectomy and fusion and conventional titanium plate with cage internal fixation for the treatment of single segmental cervical intervertebral disc herniation.

METHODSFrom August 2011 to March 2014, clinical data of 139 patients with single cervical disc herniation treated with anterior cervical discectomy and interbody fusion with internal fixation were retrospectively analyzed. The patients were divided into two groups according to its operation method. There were 63 patients in group A which performed anterior discectomy and interbody fusion with Zero-profile;76 patients in group B which performed anterior cervical discectomy and cage plate internal fixation. JOA score and Odom functional rating between two groups were compared before and after operation. Videofluorographic swallowing study (VFSS) were used to evaluate thickness of prevertebral soft tissue. Bazaz dysphagia score were used to assess incidence of dysphagia. Postoperative AP X-ray and CT of cervical vertebra at 12 months were applied for evaluating bone graft fusion. Postoperative MRI was applied for evaluating the incidence of adjacent segment degeneration. Blood loss,operative time, preoperative and postoperative JOA score, Odom functional rating and VFSS score, Bazaz score, fusion rate between vertebral bodies and incidence of adjacent segment degeneration were compared between two groups.

RESULTSThere were no statistical meaning between two groups in JOA score, Odom functional rating before and after operation (P > 0.05); and no significant meaning in VFSS score between two groups before operation (P > 0.05); There were no significant difference in operative time and blood loss. There was statistical meaning in VFSS, Bazaz dysphagia score at 2 days, and 6 months after operation (P < 0.05). All patients obtained bone union at 1 year after operation, and no obvious meaning in fusion rate (P > 0.05). Eight patients (12.7%) in group A occurred adjacent segment degeneration and 19 patients (25%) in group B occurred adjacent segment degeneration, and there was significant meaning between two groups (P < 0.05).

CONCLUSIONBoth of Zero-profile implant for anterior cervical discectomy and fusion and conventional cage internal fixation for the treatment of single segmental cervical intervertebral disc herniation could obtain satisfied clinical results. While Zero-profile implant for anterior cervical discectomy and fusion has advantages of lower incidence of adjacent segment degeneration, and its mid and long term following-up results still further observation.

Objective To discuss human papilloma virus(HPV)prevalence and HPV genotypes distribution and the infection factors,to provide scientific guidance for the prevention and treatment of cervical cancer.Methods From March to November in 2009,605 women received cervical HPV testing in the Tumor Hospital of Harbin Medical University,to obtain specimens of cervical cytology,rapid flow-through hybridization technique (namely Hybribio flow-through hybridization)was used to detect HPV genotypes simultaneously.Single-factor and multivariate factors non-conditional Logistic regression analytic method was used to discuss the relationship between HPV infection of females and age,marital condition,level of education,level of income,occupation,initial age for sex,contraception,number of pregnancies,delivery approach and smoking.Results HPV infection rate was 21.49%(130/605),the positive rate of HPV infection in high-risk subtypes was 15.70%(95/605),the most common type was 5.29%(32/605)in the samples.Single factor non-conditional logistic regression model analysis showed that initial age for sex was the risk factor(X2=4.4618,P<0.05),HPV prevalence increased with a lower initial age for.sex reduced.But there was no significant difference in age,marital condition,education,income,occupation,contraception,number of pregnancy,delivery approach and smoking teams(X2=0.0525,1.8510,1.0348,0.2592,1.1176,1.5664,2.8835,1.4597,2.6161,all P>0.05).The analysis of multivariate factors nonconditional Logistic regression showed that the age of initially having sex,marital status and number of pregnancies were the risk factors(X2=21.6637,8.0574,15.7573,all P<0.05).Conclusions The risk factors for HPV infection are mainly about having sex too young,marital status and number of pregnancies,attention should be paid to screening for HPV.

Objective To study the pathogens associated with infectious keratitis for early diagnosis and treatment.Methods This study was conducted with the patients with confirmed diagnosis of infectious keratitis in our hospital during the period from January 2011 through December 2015.The specimens from corneal ulcer were subject to bacterial and fungal culture.The pathogens and associated risk factors of infectious keratitis were analyzed retrospectively.Results Of the 1 046 corneal specimens,369 (35.3％) were positive for microorganisms.The most frequently isolated microorganism was fungal species (53.1％),followed by grampositive cocci (31.2％),gram-negative bacilli (11.1％),and gram-positive bacilli (4.6％).Of the fungal strains,most were Fusarium (69.4％),followed by Aspergillus species (21.9％).Coagulase negative Staphylococcus accounted for more than half (50.4％) of the gram positive cocci.Conclusions Infectious keratitis is primarily associated with fungal infection,especially filamentous fungus such as Fusarium.

Helicobacter pylori (HP) is an infectious pathogen which can easily infringe gastric mucosa. If the body is infected by HP, it can release cytokines, such as TNF-alpha, IL-1 and IL-6. These cytokines can regulate the absorption and transformation of bone, promote the formation of osteoclast, and then cause localized or systemic osteoporosis. HP infection may decrease the level of estrogen and vitamin B12, which is considered as a risk factor for osteoporosis. Helicobacter pylori infection is related with the occurrence of gastritis, peptic ulcer and gastric malignancies, and these diseases and treatments are associated with osteoporosis. Meanwhile the application of proton pump inhibitor (PPI) can influence absorption of calcium, decrease the level of serum calcium and increase the risk of fracture. Gastrostomy may cause bone metabolism disorders.

OBJECTIVETo explore the efficacy and safety of zero-profile implant for anterior cervical discectomy and fusion (ACDF) in treating single cervical disc herniation.

METHODSFrom August 2011 to June 2012,30 patients with single cervical disc herniation were treated with ACDF using zero-profile implant in one motion segment. There were 18 males and 12 females with a mean age of 55.3 years old (ranged, 36 to 68). Incidence of dysphagia, height of intervertebral space and condition of bone fusion were observed after operation. Spinal nerves function and clinical results were assessed according to Japanese Orthopaedic Association (JOA) score, Odom criteria.

RESULTSAll patients were followed up from 12 to 24 months with an average of 15.9 months. The mean intraoperative blood loss was (85.3 +/- 14.2) ml (70 to 120 ml) and operative time was (90.0 +/- 12.8) min (70 to 120 ml). Preoperative, postoperative at 3 months and 1 year, JOA score was 8.72 +/- 2.36 (5.0 to 13.0), 14.72 +/- 1.66 (11.5 to 17.0) and 15.65 +/- 1.03 (13.5 to 17.0), respectively. One year after operation, according Odom criteria to assess, 22 cases got excellent results, 7 good, 1 fair. All dysphagiaes vanished completely at 3 months after operation. The lost height of intervertebral space was (0.34 +/- 0.13) mm (0.1 to 0.6 mm) and (0.39 +/- 0.15) mm (0.2 to 0.7 mm) at 3, 12 months after operation, respectively. All patients obtained bone fusion at 1 year after operation.

CONCLUSIONThe zero-profile implant is a valid alternative to anterior cervical plate in treating single cervical disc herniation with ACDF, it has advantages of convenient procedure, satisfactory effect, lower incidence of postoperative dysphagia, reliable stability and less implant-related complications.

Objective To explore the relationship between the radiological characteristics and clinical and pathological manifestations of intracranial juvenile xanthogranuloma. Methods The radiological and clinical characteristics of two intracranial juvenile xanthogranuloma cases were analyzed respectively. In combination with reviewing literatures, the radiological characteristics and discipline of intracranial juvenile xanthogranuloma disease were also analyzed. Results Intracranial juvenile xanthogranuloma disease was accidently detected in one case. The other case was detected with headache and numbness in face. No abnormal sign was found in skin. On plain CT isodensity signals appeared and on contrast-enhanced CT homogeneous enhancement was found.On MR imaging,masses showed isointense signals on T1WI and iso-or hypo-intensity signals on T2WI, and enhanced homogeneously. Lesions were solitary or multiple in the external of brain. After operation intracranial juvenile xanthogranuloma was confirmed by pathology, and no recurrence occurred. Conclusion Intracranial juvenile xanthogranuloma is a kind of rarely encountered disease with typically radiological characteristics, which is difficult to detect before surgery and can be confirmed by post-operative pathological and immunohistochemical examinations.[Chinese Medical Equipment Journal,2018,39(5):71-74]

OBJECTIVETo investigate the correlation of International Prostate Symptom Score (IPSS) with the levels of interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2) in the prostate tissue and expressed prostatic secretion (EPS) in patients with benign prostatic hyperplasia (BPH) complicated by prostatitis.

METHODSWe divided 80 BPH patients to be treated by transurethral resection of the prostate (TURP) into a simple BPH group (n = 30) and a BPH with prostatitis group (n = 50) based on the pathologic features. We statistically analyzed IPSS and the levels of IL-8 and COX-2 in EPS before surgery and the IL-8 and COX-2 levels in the prostate tissue after surgery.

RESULTSIPSS was positively correlated with the IL-8 and COX-2 levels in the prostate tissue and EPS of the BPH patients, moderately in the simple hyperplasia group (r > 0.5) and highly in the other (r > 0.8). The levels of IL-8 and COX-2 in the prostate tissue and EPS were significantly higher in the BPH with prostatitis group than in the simple BPH group (P < 0.05).

CONCLUSIONThe levels of IL-8 and COX-2 in EPS indirectly reflect those in the prostate tissue. IPSS and the levels of IL-8 and COX-2 in EPS can help determine whether BPH is complicated by histological prostatic inflammation.

Influenza is a global contagious disease, which causes hundreds of thousands of people deaths. And new subtype of influenza may cause pandemic influenza, and lead to more serious consequence. Drugs for anti-influenza have played very important roles in influenza treatment and prevention, especially neuraminidase inhibitors are effective on both influenza A and B which have more safety and tolerance, therefore they have been widely used for influenza treatment. However, several viral drug-resistant cases have been reported. In this paper, the clinic therapy, prevention and drug resistance of neuraminidase inhibitors, including zanamivir, oseltamivir and peramivir, and progress in the research and development in our country are presented in order to promote research and development of new drugs for influenza treatment and prevention.

OBJECTIVETo assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.

METHODSThis was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.

RESULTSAfter treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.

CONCLUSIONThe combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.
