Journal of Zhejiang Chinese Medical University 2016;40(9):693-695
Objective] To sum up Pro. Fu Huazhou’s clinical experience in treating alopecia areata. [Method] By following the teacher clinic and sorting out the related medical materials. Summarize the mentor's academic view and clinical experience in the differentiation and treatment of alopecia areata, for proven cases.[Result] In professor Fu Huazhou's opinion, alopecia areata disease in Shaoyin and Jueyin, more close relationship with liver and kidney, virtual in the clinical setting is more, which is given priority to liver and kidney deficiency, embodies the JingXie homology, qi complement each other in the body, qi deficiency, blood deficiency, blood deficiency is also empty gas, the lung and fur, deficiency of lung function of dispersing pertains to drop, more hair loss. Alopecia areata can be roughly divided into blood deficiency and excessive wind, qi and blood stasis, qi and blood deficiency, liver and kidney deficiency syndrome and treatment according to patients' clinical performance, treats dialectically, and leaching liquid combination traditional Chinese medicine for external use at the same time, helps new hair regeneration, curative effect is remarkable. [Conclusion] Fu Huazhou ’s treatment of alopecia areata from liver and kidney, internal and external use, shows originality, curative effect, worth learning and promotion.
3. Influence of inserting glycines on biological properties of HIV Tat-(Gly)n-thymidine kinase fusion proteins
Academic Journal of Second Military Medical University 2006;27(3):244-248
Objective: To study the influence of inserting glycines(Gly) on biological properties of HIV Tat-(Gly)n-thymidine kinase (-TK) fusion proteins. Methods: Different fragments containing 0, 2, 4 or 6 Gly were inserted between the HIV Tat gene and TK using gene splicing by overlap extension (SOEing) PCR, and the products were cloned into PBK vector. The vectors were then transferred into E. coli after sequencing. After IPTG induction, bacilli were collected and destructed by ultrasound; the fusion protein was collected and identified by monoclonal antibody of HIV protein. HepG2 cells were incubated with DMEM supplemented with 1 μg/ml fusion protein containing 0, 2, 4 or 6 Gly for 24 h. HepG2 cells of different groups were detected by immunofluoreseence assay with HIV Tat monoclonal antibody; the apoptosis rate of HepG2 cells was determined by cell flow cytometry after they were incubated with gencilovir (10 μg/ml) for 3 d and the survival rate of cells was recorded by trypan blue in different groups. Results: The recombined genes containing 0, 2, 4 or 6 Gly were successfully constructed, inserted into PBK vectors, and expressed into E. coli. Their proteins were obtained and purified. The level of fluorescence in different groups was similiar, but the cell survival rate and apoptosis rate were different. The highest apoptosis rate was 14.77%, which was found in the group containing 4 Gly, followed by 12.69% in 2 Gly group, 8.31% in HIV Tat-TK group, 4.36% in 6 Gly group, and 1.0% in group containing no Gly. Significant differences were found between each 2 groups (P<0.05). Trypan blue showed similar results in the cell death rate of different groups: the highest cell death rate was 80.2%, which was found in the group containing 4 Gly, followed by 65.4% in 2 Gly group, 58.4% in HIV Tat-TK group, 56.7% in 6 Gly group, and 9.1% in the group containing no Gly. Conclusion: The number of Gly inserted into HIV Tat-TK protein does not alter the transcellular function of upstream Tat protein, but does substantially influence the TK protein-mediated cytoxic effects of gencilovir, and the influence is the smallest when 4 Gly are inserted.

16S rDNA sequences of 30 Bacillus strains originally identified as Bacillus licheniformis from China Center of Industrial Culture Collection (CICC) were determined and analyzed. The results indicated that 24 strains are affiliated to Bacillus licheniformis;3 strains are affiliated to Bacillus cereus and 1 strain is affiliated to Bacillus subitilis;the similarity levels of 16S rDNA among the rest of 2 strains and other strains of Bacillus licheniformis,range from 96.4% to 97.4%,further tests are needed to clarify their position. Also we testified that 5' terminal 500bp of 16S rDNA is available to differentiate the strains of Bacillus licheniformis、Bacillus subtilis and Bacillus cereus.

Objective To investigate the clinical effects of two minimally invasive surgical treatments for billary acute pancretitis.Method In this study,63 patients with billary acute pancretitis were prospectively divided into two groups.Patients in group A received laparoscopic cholecystectomy (LC) and laparoscopic transcyctic common bile duct exploration (LTCBDE) within 72 hours of onset,group B underwent endoscopic nasobiliary drainage (ENBD).The two groups were evaluated by blood amylase and urine amylase,alanine aminotransferase,aspartate aminotransferase on postoperative day 1,3,5,local complication and the recurrence rate within 6 months.Result Blood amylase was lower in group A than that in group B (P =0.04) on postoperative day 1.There were no significant differences in amylase,aminotransferase of two groups on postoperative day 3,5 (all P > 0.05).The incidences of local complications and pancreatic necrosis infection were 2.7%,7.7% respectively(P =0.13) ; the incidences of pancreatic pseudocyst were 5.4%,7.7% (P =0.42) ; the recurrence rate within 6 months were 2.7% and 19.2% respectively(P =0.006).Conclusions The clinical curative effects of early LC and LTCBDE or ENBD on billary acute pancretitis showed no significant differences,but the recurrence rate of acute pancretitis within 6 months revealed that early LC and LTCBDE may be more effective.
