OBJECTIVE:To discuss clinical efficacy and safety of leuprolide acetate in the treatment of endometriosis. METH-ODS:66 endometriosis patients were divided into observation group(37 cases)and control group(29 cases)according to random number table method. Observation group was treated with Leuprolide acetate microsphere for injection,3.75 mg/time,on the upper arm,abdomen or buttocks since the first-fifth day of menstrual cycle(administration time was available at hysterectomized patients disposal),and then every 4 weeks;one administration was recognized as a treatment course. Control group was treated with Ethi-nyl estradiol cyproterone tablet orally,1 tablets per day for 3 weeks,one week drug withdrawal,as a treatment course. 2 groups were given 3-5 courses of treatment according to their tolerance or the improvement of clinical symptoms. The improvement of clini-cal symptoms were compared between 2 groups,and the levels of FSH,LH and E2 were compared before and after treatment;the occurrence of ADR and the time of the return of menses were recorded. RESULTS:2 patients in observation group and 1 patient in control group withdrew from the test. After treatment,total effective rate was 97.14% in observation group,which was significant-ly higher than 75.00% in control group,with statistical significance (P<0.05). Before treatment,there was no statistical signifi-cance in the levels of FSH,LH and E2 between 2 groups (P>0.05). After treatment,the levels of FSH,LH and E2 were de-creased significantly,and the observation group was more significant than the control group,with statistical significance (P<0.05). Total incidence of ADR was 20.00% in observation group,compared to control group (21.42%),there was no statistical significance (P>0.05). The time of the return of menses in observation group was (89.75 ± 3.34) d after drug withdrawal,com-pared to control group [(88.46±2.94)d],there was no statistical significance(P>0.05). CONCLUSIONS:Leuprolide acetate can effectively improve clinical symptoms of patients with endometriosis,and reduce the levels of FSH,LH and E2 with slight ADR, and it doesn’t influence the time of the return of menses.

Objective:To evaluate the efficacy of Qinggan Huashi Huoxue Decoction combined with conventional Western medicine in the treatment of alcoholic cirrhosis with spleen deficiency and phlegm stasis syndrome.Methods:Randomized controlled trial. A total of 110 patients from Tangshan Fengrun District Hospital of Traditional Chinese Medicine from March 2020 to March 2022 were selected as observation objects and divided into 2 groups with 55 patients in each group by computer random drawing method. The control group was treated with conventional Western medicine, while the observation group was treated with Qinggan Huashi Huoxue Decoction on the basis of the control group treatment. Both groups were treated for 3 months. The traditional Chinese medicine syndrome score was performed before and after treatment, and the levels of proline peptidase (PLD), type Ⅳ collagen (Ⅳ-C) and type Ⅰ procollagen aminopeptidase (PINP) were detected by phthalaldehyde contrast colorimetry, and the levels of pentamylin 3 (PTX3), protein kinase B (Akt) and B cell activating factor receptor (BAFF-R) were determined by ELISA. Adverse events were recorded and clinical efficacy was evaluated.Results:The total effective rate in the observation group was 92.73% (51/55), while that in the control group was 76.36% (42/55), the difference between the two groups was statistically significant ( χ2=5.64, P=0.018). After treatment, the score and total score of costal pain and fullness, swelling and firmness, anorexia, white and greasy tongue coating in the observation group were significantly lower than those in the control group ( t values were 11.02, 7.36, 7.47, 6.38, 9.37, respectively, P<0.01). After treatment, the levels of serum PLD[(143.28±16.38)U/L vs. (160.69±18.35)U/L, t=5.25], Ⅳ-C[(71.93±8.33)μg/L vs. (83.12±9.91)μg/L, t=6.41], and PINP[(32.36±5.32)ng/L vs. (39.02±5.61)ng/L, t=6.39] in the observation group were significantly lower than those in the control group ( P<0.01); The levels of PTX3[(36.82±4.96)ng/L vs. (42.14±5.83)ng/L, t=5.15], Akt[(69.22±7.94)ng/L vs. (77.24±8.63)ng/L, t=5.07], and BAFF-R[(15.29±3.64)ng/L vs. (19.92±4.15)ng/L, t=6.22] in the observation group were significantly lower than those in the control group ( P<0.01). During the treatment period, the incidence of adverse reactions was 12.73% (7/55) in the observation group and 9.09% (5/55) in the control group, with no statistically significant difference between the two groups ( χ2=0.37, P=0.541). Conclusion:Qinggan Huashi Huoxue Decoction combined with conventional Western medicine therapy can improve the Traditional Chinese Medicine syndrome and the degree of liver fibrosis damage in patients with alcoholic cirrhosis with spleen deficiency and phlegm stasis syndrome, inhibit the expression of serum inflammatory factors, and improve clinical efficacy.

Objective:To study the effect of various concentrations of Enterococcus faecalis (Ef) supernatants on human periodontal ligament cell (hPDLC) and the inflammatory response of hPDLC under static pressure. Methods:The method of methyl thiazolyl tetrazolium (MTT) was used to detect the effect of various concentrations of Ef supernatants on the proliferation of hPDLCs and the flow cytometry was used to detect the expression of Toll-like receptor 2 (TLR-2) on the surface of hPDLC after 24-hour-stimulation of Ef supernatant. Furthermore, the hPDLCs were divided into non inducing group without Ef supernatant and inducing group with 5% Ef supernatant, and hPDLCs in each group were loaded with 0, 49 and 196 Pa static pressures respectively. The expressions of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) mRNA and protein were detected by reverse transcription-PCR (RT-PCR) and enzyme linked immunosorbent assay (ELISA) after 24 hours.Results:MTT results showed that the supernatant of Ef with concentratio n≥5% could significantly inhibit the proliferation activity of hPDLCs at 48 hours of cell culture ( P<0.05). Flow cytometry showed that the positive cell rates of TLR-2 increased with increasing volume fractions of the Ef supernatants. The values were (2.12±0.07)%, (2.41±0.32)%, (2.65±0.27)%, (4.76±0.46)%, (9.91±0.92)% and (12.01±1.35)%, respectively. The differences were statistically significant when the concentrations≥5% ( P<0.05). There were no significant differences in the expressions of IL-1β and TNF-α mRNA between the non inducing group and the control group under the pressure of 49 Pa ( P>0.05). However, there were significant differences in the expressions of IL-1β and TNF-α mRNA between the non inducing group and the control group under the pressure of 196 Pa ( P<0.05), while the expressions of IL-1β and TNF-α in the inducing group were significantly lower than that in the control group under the pressures of 49 and 196 Pa ( P<0.05). Compared with the control group, the mRNA expression was significantly increased ( P<0.05). The result of ELISA was consistent with that of PCR. Conclusions:High concentration of Ef supernatant could inhibit the proliferation of hPDLC. Ef supernatant might promote the expression of TLR-2 on the surface of hPDLC. Excessive mechanical pressure induced the inflammatory response of hPDLC. The presence of inflammatory mediators could lead to the intolerance of hPDLC to pressures and small pressure could aggravate the inflammatory response.
