Chinese Journal of Biologicals 2024;37(12):1434-1440+1452
Objective To establish a universal qPCR analysis method to investigate the biodistribution of oncolytic virus product GC001 in tissues and organs, and to detect samples collected during the concomitant biodistribution study of the repeated-dose toxicity in BALB/c mice.Methods Primers and probe were designed according to the specific sequence of drug, the impacts originated from incorporated genome of different tissues and/or animal species on PCR reaction system were investigated, and the standard curve for detection was constructed and verified methodologically. Ninety BALB/c mice were randomly divided into three groups consisting of control group(normal saline), and GC001 low-and high-dose groups(9. 7 × 10~6, 1. 51 × 10~8pfu), with fifteen animals per sex per group. The animals were subcutaneously injected once every two weeks for a total of three doses followed with an eight-week recovery phase. On day 18, day 31(2 d after the end of dosing)and day 85(the end of recovery period), tissues and organs were collected including blood, gonad, kidney, liver, lung, heart,brain, spleen, lymph nodes(mesenteric and inguinal), injection site, skin, bone marrow, spinal cord and sciatic nerve and subjected to qPCR to determine the copy number of the drug.Results A universal standard curve named pEASY was constructed with the limit of quantitation(LOQ) of 10 copies/μL and quantitative range between 1. 0 × 10~1 and 1. 0 ×10~7copies/μL, which manifested excellent precision, repeatability and consistency. GC001 spread broadly in the body of mice and achieved many tissues and organs, and mainly accumulated in the injection site, inguinal lymph node, sciatic nerve,spinal cord, skin, bone marrow and blood, which declined gradually with time extension and wouldn't persist perpetually. Its systematical distribution was thought of the reason of blood flow.Conclusion This study revealed the distribution profile and metabolic trends of WR strain vaccinia virus product GC001 in mice, which has certain reference significance for the biological distribution research of other vaccinia virus carrier drugs.

Objective To find out the problems in information service for diabetic patients by investigating their use of information service. Methods The enthusiasm and channels to access information in diabetic patients and the types of information they wanted were investigated in 14 Wuhan hospitals, which were analyzed by descriptive sta-tistics, chi-square test, and Five-Point Likert Scale scoring. Results About 1/3 of the patients never initially searched the health information on diabetes,the majority of the patients acquired the health information on diabetes from medical institutions,diabetic patients did not show enough concern for the information on the etiology,influencing factors and treatment plan of diabetes. Conclusion Diabetic patients lack of enthusiasm to access information,medical staff and medical institutions are the chief force of information service for diabetic patients, and the special informa-tion accessed by diabetic patients is quite less.

Objective To study the clinical,image and pathological features of cerebral gliomatosis.Methods 2 cases with cerebral gliomatosis underwent routine MRI scan, contrast enhance MRI scan and pathologic examination of the lesions. Their clinical manifestations were observed during the past 2 years.Results Main clinic features of the 2 patients were headache, dizziness, nausea, vomit, diplopia, hemiplegia, hemianesthesia and ataxia. Cranial MRI scan showed long T 2 signals in the bitemporal lobes, biparietal lobes, corpus collosum, thalamus, caudate nucleus and putamen. Brain stem and cerebellum were also involved in 1 patient. The borders of the lesions were unclear and no mass-effect phenomenons were found. Contrast enhancement occurred only in 1 patient after Gd-DTPA injection. The biopsies in the 2 patients showed diffuse infiltrative growth of most astroglioma cells. The shape of nucleus was round or ellipse and the staining of nucleus was comparatively deep. Cleavage of nucleus was seldom. The 2 patients died in 4 to 6 months after the onset of the disease.Conclusions MRI scan and pathologic examination are essential diagnostic methods for cerebral gliomatosis. The prognosis of cerebral gliomatosis is poor.

Objective To examine the interrelation between the cognitive deviation and loneli-ness levels of medical students and its influencing factors. Methods Totally 220 medical students in grade two of one medical school were selected by method of cluster random sampling. The data of the research were obtained through cognitive bias questionnaire (CBQ) and emotional-social loneliness questionnaire. Interrelation between the cognitive deviation type and condition of emotional-social lone-liness of medical students were analyzed by Pearson product-moment correlation two-tailed test. Multi-ple stepwise regression analysis was conducted by taking score of emotional-social loneliness as de-pendent variable and score of CBQ as independent variable. Differences in cognitive deviation and loneliness levels between rural and urban students as well as between students from single child family and students from non single child family were analyzed by independent-sample t test. Results Neg-ative cognitive deviation of depression-distortion type was positively correlated with medical students' emotional isolation (r=0.161, P=0.021),social isolation (r=0.266,P=0.000), emotional loneliness (r=0.340, P=0.000) and social loneliness (r=0.385, P=0.000). The regression equation was: score of emotional-social loneliness=27.165+1.908 (depression-distortion)+0.836 (depression-non distortion).Students from non single child family had higher scores than students from single child family in the perspectives of depression-distortion”(P=0.017), social isolation(P=0.001), emotional loneliness(P=0.016), social loneliness(P=0.000). Rural students had higher scores in the above four perspectives than urban students(P<0.05). Conclusions Negative cognitive deviation levels of medical students is positively correlated with emotion and social isolation conditions and loneliness experiences. Regres-sion analysis shows that unhealthy cognitive disposition and thinking mode probably are one of the im-portant reasons leading to medical students' stress disorder. Students from single child family and rural area may experience social loneliness more deeply and students from single child family have obvious cognitive deviation.

Objective To observe the clinical efficacy of comprehensive muscle-region therapy based on Chuang Medicine in treating cervical spondylosis of neck type.Method A hundred patients with cervical spondylosis of neck type were randomized into a treatment group and a control group, 50 cases in each group. The treatment group was intervened by the comprehensive muscle-region therapy based on Chuang medicine (muscle-region tuina, fire-needle acupuncture of Chuang medicine, and cupping), while the control group was by regular acupuncture treatment. The Visual Analogue Scale (VAS) score and symptoms and signs scores were observed before and after intervention, and the clinical efficacies were compared.Result The VAS scores respectively after 1 and 2 treatment courses were significantly different from that before intervention in the treatment group (P<0.05,P<0.01). The VAS score after 2 treatment courses was significantly different from that before intervention in the control group (P<0.05). After 2 treatment courses, the VAS score in the treatment group was significantly different from that in the control group (P<0.05). After treatment, the symptoms and signs scores (pain intensity, pain-affected area, number of tender points, limited motion, and general score) were significantly different from that before intervention in the treatment group (P<0.01, P<0.05). In the control group, the pain intensity, limited motion and general score after treatment were significantly different from that before intervention (P<0.05,P<0.01). After treatment, the symptoms and signs scores in the treatment group were significantly different from that in the control group (P<0.05,P<0.01). The total effective rate was 100.0% in the treatment group versus 84.0% in the control group, and the difference was statistically significant (P<0.05).Conclusion Comprehensive muscle- region therapy in Chuang medicine is an effective approach in treating cervical spondylosis of neck type.
