RESUMO
OBJECTIVE: To investigate the application value and safety of peripheral prostate nerve block (PPNB) combined with dezocine in transrectal prostate biopsy. METHODS: Using a random number table, we divided 97 patients undergoing prostate biopsy in our hospital from October 2018 to October 2020 into an experimental group (n = 49) and a control group (n = 48), the former anesthetized by PPNB combined with dezocine and the latter by PPNB only. We compared the hemodynamic indexes before operation, during puncturing and at 5 minutes after operation, the pain scores during the movement of the probe in the rectum, at puncturing and at 5 minutes after surgery, and the adverse reactions to anesthesia between the two groups of patients. RESULTS: The heart rate was significantly lower in the experimental group than in the control during puncturing and at 5 minutes after operation (P < 0.05), while the mean arterial pressure (MAP) and blood oxygen saturation (SpO2) were remarkably higher in the former than in the latter group during puncturing (P < 0.05). The Visual Analogue Scale (VAS) score for pain was markedly lower in the experimental group than in the control during the movement of the probe in the rectum, at puncturing and at 5 minutes after surgery (P < 0.05). There was no statistically significant difference in the total incidence rate of adverse reactions to anesthesia between the two groups (P > 0.05). CONCLUSION: PPNB combined with dezocine for prostate biopsy is more conducive to maintaining the stability of the patient's hemodynamics, and has a good analgesic effect and a high safety.

OBJECTIVE: To analyze the inoculation ratio and echinacoside content of Cistanche tubulosa and provide theoretical basis for Tamarix introduction, resource protection and screening of C. tubulosa. METHOD: 8 Tamarix species were introduced in the North China Plain and inoculation of C. tubulosa was conducted on all species. Phenylethanoid glycosides fingerprinting and echinacoside content of C. tubulosa were analyzed by using HPLC. RESULT: The adaptability of 8 Tamarix species were significantly different, phenylethanoid glycosides component of C. tubulosa on T. gansuensis and T. austromongolica were basically identical in contrast to T. chinensis, echinacoside content showed no obvious difference in C. tubulosa plant growing 4 months. CONCLUSION: T. gansuensis and T. Austromongolica are suitable for the host introduction plant of C. tubulosa resource protection and screening in North China Plain.

OBJECTIVE: To give some theory support of Cistanche tubulosa cultivation by searching dry matter accumulation and echinacoside content of C. tubulosa. METHOD: Dry matter accumulation content of C. tubulosa culturing in Huabei plain was analysed in different growth season of C. tubulosa. Echinacoside content was determined by HPLC. RESULT: Dry matter accumulation of C. tubulosa showed "S" variation. Dry matter accumulation increased fastest in September among growing seasons. Dry matter amount was 138.58 g after C. tubulosa grew a year. Dry matter amount decreased significantly along with inoculation time retarded. Echinacoside content was 30.59% when C. tubulosa grew in 5 months, decreased guadully after that, and 9.76% in annual. CONCLUSION: Variation rule of dry matter accumulation and echinacoside content was found in C. tubulosa that grew one year in Huabei plain.
