Nonclinical evaluation of vaccines is an important part of innovative vaccine research and development. Information on vaccine efficacy and safety is obtained through nonclinical research to support the clinical development and licensure of the vaccine. In this paper, combined with existing vaccine evaluation experience, the strategies, considerations and concerns of vaccine nonclinical evaluation are summarized by consulting the relevant domestic and foreign literature and guidelines of vaccine nonclinical evaluation in recent years, so as to provide a reference for vaccine researchers. Because of the different characteristics and concerns of therapeutic vaccines, the discussion in this paper mainly focuses on innovative preventive vaccines.

Purpose:To compare old and new clinical staging of primary liver cancre. Methods:317 cases of primary liver cancer(PLC) patients,hospita lized and dead,were investigated retrospectively for overall median survival and survival after various therapies,according to various stages,and therapies and comparison among groups and test of median survival were carried out. Results:Survival in patients with new stage Ⅱa+Ⅱb or old Ⅱw ere significantly longer than newⅢa+Ⅲb or oldⅢ, but no significant differenc es were observed between new stageⅡa+Ⅱb and oldⅡ , or new stage Ⅲa+Ⅲb and oldⅢ. Median survival by new staging , decreased in peoper order from stageⅡ a ,Ⅱb , Ⅲa to Ⅲb respectively, significant different was found only between s tage Ⅲa and Ⅲb but not betweenⅡa andⅡb . Survival decreased respectively fr om interventional treatment ,systemic chemotherapy and palliative therapy;the in terventional treatment group did much better than the palliative group but no si milar differences were observed in the other groups. Conclusions:New clinical staging of PLC did not show significan t superiorly over the old one as judged by median survival.It can be questioned whether basing on largest diameter is less than 5/10 cm or more than 10 cm to di stinguish Ⅱa and Ⅱb is valid.Interventional treatment should be applied as soo n as possible to prolong survival whether it be the new or old clinical staging.

OBJECTIVE:Inhaled glucocorticoids(GC) are the first-line medicine for bronchial asthma during relieve phase, thereby this study was designed to explore if patient tends to suffer osteoporosis due to long term inhalation of glucocorticoids. DATA SOURCES:Literatures about GC and osteoporosis were computer-searched in Medline and Embase from January 1980 to December 2003, with the key word of " asthma, bone density, bone metabolism and inhaled glucocorticoids" and language limited to English.Meanwhile it was also computer-searched in CBM, CBM disc and manually searched in Chinese Journal of Clinical Rehabilitation between January 1990 and April 2004 with language limited to Chinese. DATA SELECTION: Literatures about the comparison of bone density and bone metabolic change between inhaled GC group and control group were consorted deleting randomized controlled trial(RCT) so as to look up the whole content of healthy controls;While patients in the treatment group received GC inhalation.Exclusive standards:obvious non-RCT. Quality assessment is mainly focused on the reality of data,the strictness of design and implementation,and the rationality of statistical management. DATA EXTRACTION:Totally 30 randomized and nonrandomized studies about the influence of inhaled GC on the bone density and bone metabolism of patients with asthma were referred to amongst which 18 studies were admitted with the other 12 excluded for similarity in content in 8 and Meta-analysis in 4. DATA SYNTHESIS:A total of 1 153 asthmatic patients in 18 studies were divided into GC inhalation group and non-inhalation control group for comparing the difference of bone density and/or bone metabolism between them. CONCLUSION:Although the results of studies on the influence of long-term inhaled GC on bone quantity were different, but there was still not enough evidence to demonstrate that osteoporosis was due to long-term GC inhalation.

Acute kidney injury( AKI) is a variety of causes leading to rapid impaired renal function, causing glomerular filtration rate reduced,blood urea nitrogen elevated,serum creatinine increased,urine out-put decreased,resulting in the disorder of the human body environment,so the body can not maintain homeo-stasis. AKI increases the risk of mortality and chronic kidney disease in neonate. To understand the progress of AKI on diagnostic criteria,pathogenesis,early biomarker,treatment and prognosis,it is extremely important to guide clinical diagnosis and treatment,improve the outcome and reduce the mortality of AKI in neonate.

Objective To investigate the effect of ramipril on urinary protein in elderly type 2 diabetic patients with nephropathy in different periods.Methods 120 type 2 diabetic patients with nephropathy (64 males, 56 females) with mean aged (68±3) years were randomized into treatment group and control group (n =60, each).According to test results of 24 h proteinuria and renal function, they were divided into 3 subgroups: the normal urine albumin (normal control) group, the early diabetic nephropathy group, and the clinical diabetic nephropathy group.The control group received conventional treatment, while the treatment group used conventional treatment combined with ramipril 2.5 mg/d.Both groups had treatment course of 3 months.The changes in 24 h urinary total protein and urinary albumin before and 1 and 3 months after treatment, and the changes in blood urea nitrogen and serum creatinine levels in patients with renal dysfunction before and 3 months after treatment were observed and compared.Results 24 h urinary total protein and urinary albumin were significantly decreased along with the extended treatment time (P＜0.05 or 0.01).The blood urea nitrogen and serum creatinine levels were significantly declined at 3 months after treatment versus pre-treatment (P＜0.05 for both).There were no significant differences in 24h urinary total protein and urinary albumin in control group before versus after treatment (P＞0.05 for both).At 1 and 3 months after treatment, there were significant differences both in the decrement of 24h urinary total protein and urinary albumin, and in the blood urea nitrogen and serum creatinine levels between the clinical diabetic nephropathy treatment group and the control group (P＜0.05 or 0.01).Conclusions Ramipril combined with conventional treatment can effectively reduce proteinuria and promote the recovery of renal function for type 2 diabetic patients with nephropathy.

The concept of far lateral lumbar disc herniation was firstly reported by Abdullah in 1974. The diagnosis of far lateral lumbar disc herniation is based on the discography findings as well as on clinical manifestations. Far lateral lumbar disc herniation is a special type of lumbar disc herniation. Clinically, far lateral lumbar disc herniation is less seen than other types of lumbar disc herniation, it accounts for 0.7%-11.7% of total lumbar intervertebral disc protrusion. Although the incidence of far lateral lumbar disc herniation is lower, its symptoms are usually heavier and its protrusion sites are specific. Its treatment methods are more complex, including mainly conservative treatment, minimally invasive interventional therapy and surgical management, etc. This paper aims to make a review about the recent progress in its corresponding treatment.

analysis on 103 cases of spontaneous pneumothorax patients between September, 2012 and December,2014. Then the patients were randomly divided into two groups according to the different therapies on pulmonary bulla, 52 in GIA surgical stapler group and 51 in ligature group. Comparison: The postoperative situations of the two groups.Results: The operation time and intraoperative bleeding volume of observation group are obvious less than control group(t=7.58,t=16.87;P<0.01), but oxygen saturation of observation group is obvious higher than control group(t=1.34,P<0.01). The operation fee of observation group is obvious higher than control group(t=38.26, P<0.01).2 cases of postoperative recurrence in observation group(3.84%), but 10 cases in control group(19.60%).The two recurrence rates have statistical significance(x2=4.77,P<0.05). The postoperative complications incidence is 5.77% in observation group,but 21.56% in control group.The two The postoperative complications incidences have statistical significance(x2=5.47,P<0.05).Conclusion: As opposed to ligature, under the therapy for spontaneous pneumothorax with GIA surgical stapler by thoracoscopy, the operation time is shorter, intraoperative bleeding volume is less, and recurrence rate is lower in 2 years. Ligature fits the sporadic pulmonary bulla patients.
