[Clinical efficacy of Manlyman Spray combined with biofeedback therapy on premature ejaculation].

Objective： To observe the clinical effect of Manlyman Spray combined with biofeedback therapy in the treatment of premature ejaculation (PE)．Methods： A total of 60 primary premature ejaculation patients with stable sexual partners and regular sexual activity (≥１ times per week) from April 2021 to October 2022 were involved in the clinical observation, The patients' age is (34.3 ± 4.9) years old, and the course of the disease is (112.5 ± 65.5) months, and Manlyman Spray combined with biofeedback therapy was used to treat patients for 8 weeks. Manlyman Spray was sprayed 3 times on the surface of the penisqd for 4 weeks, and Biofeedback therapy is treated twice a week according to the AI setting module, for a total of 8 weeks. Before and 8 weeks after medication and at 4 weeks after drug withdrawal, the Intravaginal Ejaculation Latency Time (IELT), Premature Ejaculation Diagnostic Tool (PEDT) scores and Clinical Global Impression of Change (CGIC) scores were Obtained and compared. Results： After 8 weeks of treatment, the IELT of the patients was significantly prolonged (ï¼»351.4 ± 76.7ï¼½ vs ï¼»87 ± 16.8ï¼½,P<0.05) and at 4 weeks after drug withdrawal, the therapeutic effect still existed (ï¼»345.9 ± 80.3ï¼½ vs ï¼»87 ± 16.8ï¼½,P<0.05), the PEDT scores were significantly improved after treatment (ï¼»18.2 ± 1.1ï¼½ vs ï¼»9.0 ± 1.4ï¼½,P<0.05)and at 4 weeks after drug withdrawal(ï¼»18.0 ± 1.2ï¼½ vs ï¼»9.0 ± 1.4ï¼½,P<0.05), and so were the CGIC scores (ï¼»13.4 ± 1.3ï¼½ vs ï¼»3.3 ± 1.4ï¼½,P<0.05, and ï¼»12.6 ± 1.6ï¼½ vs ï¼»3.3 ± 1.4ï¼½,P<0.05). Conclusion： The combination of Manlyman Spray and biofeedback therapy can effectively treat primary premature ejaculation, with a long duration of treatment and good safety, and the specific mechanism needs further study.

[Identification of herbal tea ingredient Plumeria rubra and its adulterants using DNA barcoding].

ITS2 sequence was used as a barcode to identify herbal tea ingredient Plumeria rubra and its adulterants. Genomic DNAs from forty eight samples were extracted, the ITS2 sequences were amplified and sequenced bi-direstionlly, and then assembled and obtained using CodonCode Aligner. The sequences were aligned using ClustalW, the genetic distances were computed by kimura 2-parameter (K2P) model and the Neighbor-joining (NJ) phylogenetic trees were constructed using MEGA5.0. Results showed that the length of ITS2 sequence of P. rubra were 244 bp. The intra-specific genetic distances (0-0. 016 6) were much smaller than inter-specific ones between P. rubra and its adulterants(0.320 8-0.650 4). The NJ tree indicated that P. rubra and its adulterants could be distinguished clearly. Therefore, Using ITS2 barcode can accurately andeffectively distinguish herbal tea ingredient P. rubra from its adulterants, which providesa new molecular method to identify P. rubra and ensure its safety in use.
