Chinese Journal of Primary Medicine and Pharmacy 2013;20(2):252-253
Objective To study the effect of juvenile non-incarcerated oblique inguinal hernia on the development of testis and spermatic cord.Methods The volume of the testis was measured with B-ultrasound in normal and patient children.All patients were surgically treated and the spermatic veins were examined during operation.The patients were followed up for measuring the testicle volume at 3 months,6 months and 6 ~ 12 months after operation.Results Testicle volume on healthy side was larger than the involved side in patient group (P < 0.05).There were still obvious differences between the two sides after 6 months(P < 0.05).No significant difference was found after 6 ~12 months (P > 0.05).Conclusion Non-incarcerated oblique inguinal hernia has effected on the spermatic cord and testicles,which need timely treatment.
2.Sustained-released anti-tuberculosis drugs: a choice of carrier materials
Chinese Journal of Tissue Engineering Research 2015;19(21):3387-3391
BACKGROUND:Local administration of anti-tuberculosis drugs is a commonly used therapy. Due to the rapid absorption, the drugs cannot have the durable therapy effect; therefore, it is necessary to seek an optimal carrier material for the agents. OBJECTIVE:To review the new development for the carrier materials of anti-tuberculosis drugs. METHODS:A computer-based search of PubMed and VIP databases was performed by the first author to search articles related to sustained-released anti-tuberculosis drugs published from January 1990 to December 2014. The key words were osteoarticular tuberculosis; anti-tuberculosis; sustained-released drugs in English and Chinese, respectively. RESULTS AND CONCLUSION:Inorganic materials (calcium phosphate, calcium sulfate), polymer materials (polylactic acid, polyglycolic acid, polylactic-co-glycolic acid) and biomaterials (protein, glutin, alginates, chitin, demineralized bone matrix) are the main three kinds of carrier materials for anti-tuberculosis drugs. These carrier materials have their own advantages and disadvantages, which cannot be the optimal carrier materials. However, the complex of these materials is a promising technology for the optimal carrier materials in the future.

Tumors are believed to consist of a heterogeneous population of tumor cells originating from rare cancer stem cells (CSCs). However, emerging evidence suggests that tumor may also originate from non-CSCs. To support this viewpoint, we are here to present definitive evidence indicating that the number of tumorigenic tumor cells is greater than that of CSCs in tumor, and tumor can also derive from non-CSCs. To achieve this, an idealized mathematical model was employed in the present study and theoretical calculation revealed that non-CSCs could initiate the occurrence of tumor if their proliferation potential was adequate. Further, experimental studies demonstrated that 17.7%, 38.6% and 5.2% of tumor cells in murine B16 solid melanoma, H22 hepatoma and Lewis lung carcinoma, respectively, were potentially tumorigenic. Thus, based on the aforementioned findings, we propose that the scarce CSCs, if exist, are not the sole source of a tumor.

Objective:To investigate the efficacy and safety of peginterferon alpha-2a plus ribavirin in the treatment of chronic hepatitis C. Methods:Totally 85 patients with chronic hepatitis C were randomly divided into the observation group and the control group. Each patient in the observation group was injected subcutaneously peginterferon alpha-2a with the dose of 180μg once a week plus ribavirin 900-1 200 mg/d, po, and each patient in the control was treated subcutaneously with 5 MU standard interferon alpha-2b three times a week plus the same used ribavirin. After the 48-week treatment, 24-week fellow-up was carried out. HCV RNA and ALT were detected at the baseline, 4th week, 12th week and 48th week during the treatment, and 24th week after the treatment, respective-ly. The rate of rapid virological response ( RVR) , early virological response ( EVR) , end of treatment virological response ( ETVR) , sustained virological response (SVR), ALT normalization and adverse reactions were respectively assessed. Results: The rates of EVR,ETVR and SVR in the observation group were 76. 7%(33/43), 86. 0%(37/43) and 79. 1%(34/43), respectively, which were significantly higher than those in the control group [54. 8%(23/43), 66. 7%(28/43) and 57. 1%(24/43),respectively] (P<0. 05). The ALT normalization rate at 12th and 48th week after the treatment in the observation group was 81. 4% and 90. 7%, re-spectively, which were higher than those in the control group [64. 3% and 71. 4%, respectively](P<0. 05). The rate of white cell counts and platelet underlying (58. 1% and 39. 5%) in the observation group were also higher than those in the control group (35. 7%and 19.0%)(P<0.05). The decreased rate of neutrophil (58.1%) in the observation group was higher than that in the control group(19. 0%)(P<0. 01). The other adverse reactions in the two groups were similar, and there was no new or unique adverse event related to peginterferon. Conclusion:Peginterferon alpha-2a has better effect than the standard interferon alpha-2b in the treatment of patients with chronic hepatitis C with promising tolerance.
