Objective:To investigate the effects of visualized precision electrophysiological diagnosis and transcutaneous low-frequency electrical stimulation(TES)on hypoxia-induced ED in high-altitude areas.Methods:This study included 152 ED pa-tients from high-altitude hypoxic areas treated by TES based on the parameters obtained from visualized precision electrophysiological diagnosis.We followed up the patients for 1 to 3 months and compared their ⅡEF-5 scores,nocturnal penile tumescence and rigidity(NPTR)and infrared thermal metabolic technology(TMT)-based temperature of the whole body and diseased parts before and after treatment.Results:All the patients successfully completed 1 to 3 courses of TES.There were no statistically significant differences in the ⅡEF-5 scores(P<0.05)and penile tip optimal erection rigidity and duration(P<0.01)of the patients before and after treat-ment.TMT images indicated a temperature change of>1.5 ℃ in the penis and bilateral inguinal regions after treatment,suggesting the effectiveness of electrical stimulation.No recurrence was observed during the follow-up.Conclusion:TES based on the parame-ters obtained from visualized precision electrophysiological diagnosis has a definite effect on hypoxia-induced ED by enhancing oxygen supply to the penile corpus cavernosum and improving its function and structure.

Quantity is the key factor to ensure the safety and effectiveness of medicines. It is very important to study and determine the traditional measuring units and their quantity values of Tibetan medicine. Based on the literature records of Tibetan medicine and combined with modern experimental verification and investigation research, this study determined the reference, name, and conversion rate of traditional measuring units of Tibetan medicine. Meanwhile, through large sample sampling and repeated quantification of refe-rence of basic units, its weight and volume were clarified. The modern SI volume and weight unit values corresponding to the traditional volume and weight units of Tibetan medicine were deduced, and the correctness, reliability, and practicability of these determination results were demonstrated. This study also put forward some specific suggestions and reference values for formulating the standards of measuring units of weight and volume of Tibetan medicine. It is of great significance in guiding the processing, production, and clinical treatment of Tibetan medicine, and promoting the standardization and standardized development of Tibetan medicine.

OBJECTIVES:
To study the effect of breastfeeding on immune function in infants with human cytomegalovirus (HCMV) infection.
METHODS:
A retrospective analysis was performed on the medical data of 135 infants with HCMV infection who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2021 to May 2022, and all these infants received breastfeeding. According to the results of breast milk HCMV-DNA testing, the infants were divided into two groups: breast milk HCMV positive (n=78) and breast milk HCMV negative (n=57). According to the median breast milk HCMV-DNA load, the infants in the breast milk HCMV positive group were further divided into two subgroups: high viral load and low viral load (n=39 each). Related indicators were compared between the breast milk positive and negative HCMV groups and between the breast milk high viral load and low viral load subgroups, including the percentages of peripheral blood lymphocyte subsets (CD3+ T cells, CD3+CD4+ T cells, CD3+CD8+ T cells, and CD19+ B cells), CD4+/CD8+ ratio, IgG, IgM, IgA, and urine HCMV-DNA load.
RESULTS:
There were no significant differences in the percentages of CD3+ T cells, CD3+CD4+ T cells, CD3+CD8+ T cells, and CD19+ B cells, CD4+/CD8+ ratio, IgG, IgM, IgA, and urine HCMV-DNA load between the breast milk HCMV positive and HCMV negative groups, as well as between the breast milk high viral load and low viral load subgroups (P>0.05).
CONCLUSIONS
Breastfeeding with HCMV does not affect the immune function of infants with HCMV infection.

According to the taste analysis of Pudilan Xiaoyan Oral Liquid, the unpleasant taste of the oral liquid is mainly caused by the inherent taste of Chinese medicine and the taste introduced in the preparation process, which leads to its unpopularity among children. Therefore, aiming at the special children patient group, Xiaoer Pudilan Xiaoyan Syrup was developed via technology optimization and dosage form improvement to improve the unpleasant taste and enhance the medication compliance among children. Based on the material properties of Pudilan Xiaoyan Oral Liquid and Xiaoer Pudilan Xiaoyan Syrup extracts, the authors compared the properties(pH, density, turbidity, viscosity, chromaticity, particle size), taste, content of five quality markers and in vivo pharmacokinetic characteristics of these two preparations, to evaluate the suitability of Xiaoer Pudilan Xiaoyan Syrup. The results showed that compared with those of Pudilan Xiaoyan Oral Liquid, the pH, density, turbidity, viscosity and chromaticity of Xiaoer Pudilan Xiaoyan Syrup were significantly changed, and the unpleasant taste was reduced by 26%; the transfer rate of the main active ingredients chicoric acid was increased, while the transfer rate of baicalin had small difference from that of the oral liquid. In addition, pharmacokinetics revealed that the total absorption amount of baicalin in vivo was higher, and the time to peak T_(max) of baicalin and oroxindin in the syrup and the mean residence time MRT_(last )of corynoline in vivo were significantly prolonged. The absorption degree of Xiaoer Pudilan Xiaoyan Syrup and Pudilan Xiaoyan Oral Liquid in the body was the same: baicalin>oroxindin>corynoline. The new dosage form process was simpler than that of the original dosage form, safe, environmentally friendly, reasonable and feasible, meeting the mass production demand. This provided a basis for the reasonable and scientific optimization of Xiaoer Pudilan Xiaoyan Syrup, and also laid a foundation for its further safe and rational use, so as to expand the clinical application in children.

National Journal of Andrology 2021;27(9):793-797
Objective:
To investigate the application of a simplified technique for reconstruction of vesicourethral support (RVUS) in laparoscopic radical prostatectomy (LRP).
METHODS:
From January 2017 to August 2019, 122 patients with localized prostate cancer underwent extraperitoneal LRP, 65 with RVUS (the RVUS group) and 57 without RVUS (the non-RVUS group). We compared the operation time, intraoperative blood loss, rate of pelvic lymph node dissection, neurovascular bundle sparing, incidence of urethrovesical anastomotic urinary leakage (UVAUL), postoperative urinary continence, postoperative hospital stay, intraperitoneal drainage tube removal time, and urethral catheter removal time between the two groups of patients.
RESULTS:
No statistically significant differences were observed between the two groups in the operation time, intraoperative blood loss, rate of pelvic lymph node dissection, neurovascular bundle sparing, or urethral catheter removal time (P > 0.05). The incidence rate of UVAUL was lower in the non-RVUS than in the RVUS group (8.8% vs 0%, P < 0.05), and so were the rates of postoperative urinary continence immediate after (0% vs 32.3%, P < 0.05) and at 1 month (38.6% vs 56.9%, P < 0.05), 3 months (59.6% vs 80%, P < 0.05), 6 months (78.9% vs 84.6%, P > 0.05) and 12 months after catheter removal (87.7% vs 92.3%, P > 0.05). The postoperative hospital stay was dramatically longer in the non-RVUS than in the RVUS group ([9.1 ± 4.3] vs [6.7 ± 1.8] d, P < 0.01) and so was the intraperitoneal drainage tube removal time ([6.9 ± 4.5] vs [4.8 ± 1.5] d, P < 0.01).
CONCLUSIONS
The simplified technique for reconstruction of vesicourethral support in laparoscopic radical prostatectomy improves early urinary continence, especially immediate continence, decreases the incidence rate of urethrovesical anastomotic urinary leakage, and shortens the intraperitoneal drainage tube removal time and postoperative hospital stay.?
