Objective To evaluate the clinical efficacy of Compound Sophorae Flavescentis Radix (Kushen) Injection combined with gamma knife for treatment of locally advanced pancreatic carcinoma. Methods Totally 65 patients of locally advanced pancreatic cancer were randomly divided into two groups:32 cases of simple gamma knife group (group A), 33 cases of Compound Kushen Injection combined with gamma knife treatment (group B). Patients received enhancement computed tomography scanning and CA199 review at 1, 3, 6, 9, 12 months after treatment, and once every six months, a total of 36 months of follow-up. Short-term and long-term efficacy was observed after treatment, and survival curve analysis was carried out. Results Clinical benefit response was 53.13% in group A and 84.85% in group B (P=0.006);median survival time of two groups was 11.00 months in group A and 23.00 months in group B;the average survival time in group A was 16.37 months, and 22.28 months in group B (P=0.017). In the two groups, treatment of the 65 patients was completed smoothly as planned, and no one had serious complications, such as pancreatic leakage, skin burns, viscera perforation and radioactive enteritis. Conclusion Compound Kushen Injection combined with gamma knife can treat locally advanced pancreatic carcinoma safely and efficiently, which can improve patients’ life quality, especially in cancer pain control.

OBJECTIVE To observe the effects of RNA interference mediated PIK3CA gene silencing on the proliferation and invasiveness of laryngeal squamous cell carcinoma(LSCC) cells, and investigate the feasibility of PIK3CA gene as a potential therapeutic target in the treatment of LSCC. METHODS The lentiviral vector system expressing short hairpin RNA targeting PIK3CA gene(PIK3C-shRNA)was constructed and transfected subsequently into Hep-2 cells mediated by liposome in vitro. The expression of PIK3CA gene was detected by real-time RT-PCR and Western blot respectively. The proliferation of Hep-2 cells was measured by MTT, colony formation, and cell growth curve. The invasive power was determined by Boyden chamber model in vitro. RESULTS The lentiviral vector system expressing short hairpin PIK3CA- shRNA was constructed successfully. Compared with the control groups, the mRNA and protein expression of PIK3CA were significantly down-regulated(75% and 70% respectively)in the experimental group (P

Objective:To investigate the efficacy and safety of dual wavelength pulsed dye laser combined with 30% supramolecular salicylic acid in the treatment of moderate and severe facial acne.Methods:Sixty patients with moderate and severe acne that visited the Dermatology Department of the First Affiliated Hospital of Chongqing Medical University from May 2020 to January 2021, were selected and randomly divided into observation group and control group, with 30 patients in each group. The observation group was given dual-wavelength pulsed dye laser combined with 30% supramolecular salicylic acid. 30% supramolecular salicylic acid was used once every two weeks, for a total of six times. Dual-wavelength pulsed dye laser was given once a month, for a total of three times. The control group was only given dual-wavelength pulsed dye laser, once a month, a total of three times.Results:Twenty-two cases (73.33%) in the observation group were effective, while 14 cases (46.67%) in the control group were effective. The efficacy of the observation group was better than that of the control group, and the difference was statistically significant (χ 2=4.44, P<0.05). There were no obvious adverse reactions in both groups. Conclusions:Dual-wavelength pulsed dye laser combined with 30% supramolecular salicylic acid is effective and safe in the treatment of moderate and severe facial acne, which is worth popularizing.
