AIM: To study the protect effects of paecilomyceps sinensis sp nov (CN-802) on immunological liver injury in mice which induced by BCG+LPS. METHODS: LPS was injected into mice via the tail vein pretreated with BCG. The activity of serum ALT, the weighing indexes of liver and spleen, the levels of LPO in serum and hepatic tissues, and the numbers of subgroup of T lymphocyte were determined respectively. RESULTS: CN-802 at dose of 1.0 g?kg -1?d -1 decreased the serum ALT level, the liver and spleen-enlarged index and the LPO levels in serum and hepatic tissues. Analysis of CD_4/CD_8 in the peripheral blood showed that CN-802 increased the number of CD_4 lymphocyte and the ratio of CD_4/CD_8. CONCLUTION: Pretreatment with CN-802 prevents the immunological liver injury induced by BCG+LPG, and the effect of CN802 may be related with the regulatory of immune cells.

Aim To study and compare the pharmaco-kinetic parameters of roxithromycin under normoxic and hypoxic rats. Methods A highly effective and rapid ultra-performance liquid chromatography with tandem mass spectrometry ( UPLC-MS/MS) method with posi-tive electrospray ionization source was successfully de-veloped and validated for quantification of roxithromy-cin in rat plasma. Sprague-Dawley rats were randomly divided into the hypoxia and normoxic groups. Each rat obtained a single dose of roxithromycin with 10 mg · kg-1 via intragastric administration. The pharmacoki-netic parameter comparison between normoxic and hy-poxic groups was calculated by SPSS software using in-dependent sample t test method. Results The main pharmacokinetic parameters of roxithromycin between the normoxic and hypoxic rats were:the AUC(0-t) 7 576 and 3 761 μg·h·L-1 , MRT(0-t) 5. 6 and 7. 7 h, T1/2 3. 4 h and 3. 9 h, CL 1. 5 and 3. 0 L · h-1 · kg-2 , tmax3. 1 and 3. 4 h, Cmax 1 116 and 372 μg·L-1 , re-spectively. The levels of Cmax and AUC of roxithromy-cin in hypoxic rats were statistically lower than those in normoxic rats. Conclusion The exposure level of rox-ithromycin in hypoxic rats markedly decreased. Our re-sults may provide an important experimental basis to adjust the dosage for roxithromycin in hypoxic clinical practice.

OBJECTIVES:
Intrauterine adhesions (IUA) is the damage of the basal layer of the endometrium caused by various reasons, resulting in adhesion of the uterine muscle walls to each other, which is manifested as clinical symptoms such as spanomenorrhea, amenorrhea, and infertility. Hysteroscopic adhesiolysis (HA) is the main treatment, for patients with moderate or severe adhesion or angular adhesion, the incidence of postoperative adhesion is high. Traditional Chinese medicine "Yangmo decoction" can promote endometrial growth. Three-dimensional transvaginal ultrasonography (3D-TVUS) can judge IUA and evaluate uterine receptivity through three-dimensional imaging. This study aims to investigate the value of 3D-TVUS in judging the efficacy of Yangmo decoction in the treatment of intrauterine adhesions.
METHODS:
The clinical data of patients who underwent HA at two different centers in department of Gynecology of Third Xiangya Hospital of Central South University and Changsha Jiangwan Hospital from January 2021 to August 2021 were retrospectively collected. A total of 275 eligible patients were included. According to the postoperative management measures, the selected patients were divided into two groups. Yangmo decoction group (n=138): the use of Yangmo decoction and uterine-shaped silicon stent post HA; Hormone group (n=137): the use of estrogen, progesterone and uterine-shaped silicon stent post HA. The preoperative general data, preoperative and postoperative 3D-TVUS parameters of the two groups were analyzed.
RESULTS:
The endometrial thickness of Yangmo decoction group was thicker than that of hormone group (P<0.001), the intercornual distance was wider (P=0.016), the endometrial echo was more homogeneous (P=0.018), the percentage of bilaterally visible tubal opening was higher (P<0.001), the endometrial morphology was better (P=0.012), and endometrial blood flow, endometrial motility and uterine motion were better in Yangmo decoction group than that in the hormone group (all P<0.001).
CONCLUSIONS
The endometrial thickness, echo, blood flow, and peristalsis, the number of visible tubal opening, uterine motion, and the intercornual distance obtained by 3D-TVUS examination are important factors to evaluate the prognosis of postoperative drug treatment for IUA. 3D-TVUS is of great significance in evaluating the efficacy of Yangmo decoction in the treatment of IUA.

Objective:To explore the clinical application value of sound touch elastography (STE) in the evaluation of the curative effect of acupuncture and moxibustion in the treatment of stroke patients with upper limb spasm.Methods:Fifty-five patients with upper limb spasm after stroke were selected as stroke group, and thirty healthy volunteers matched with age, gender and body mass index (BMI) were selected as control group between September 2020 and March 2021. The shear wave velocity (SWV) of biceps brachii and triceps brachii were measured in both groups. In stroke group, the SWVs of biceps brachii and triceps brachii on spastic side and non-spastic side were measured before and after acupuncture treatment, and the correlations between SWV and spastic grade (X), muscle response angle (R1), passive range of motion (R2), spastic angle (R2-R1) of modified Tardieu scale (MTS) were analyzed.Results:At 0 degree, the SWV of spastic biceps brachii (3.85±0.62)m/s was significantly higher than those of the non-spastic side [(3.34±0.35)m/s] and control group [(3.15±2.66)m/s] (all P<0.001), and decreased [ (3.45±0.47)m/s] after acupuncture treatment ( P<0.001). At 90 degree, the SWV of non-spastic biceps brachii was larger than those of spastic side and control group [1.98(1.92, 2.14)m/s vs 1.98(1.92, 2.11) m/s, 1.95(1.86, 2.05)m/s, all P<0.05], and there was no significant difference between the SWV of spastic side and control group ( P>0.05). There were no significant differences in SWV of triceps brachii between the spastic side and control group at both 0 degree or 90 degree ( P>0.05). At 0 degree, SWV positively correlated with MTS (x) ( rs=0.639, P<0.001) and negatively with R1 ( rs=-0.527, P<0.001) and R2 ( rs=-0.825, P<0.001) on the spastic biceps brachii. Conclusions:STE can provide quantitative index for the objective evaluation of the curative effect of acupuncture in upper limb spasm after stroke, and it is proposed to be an effective means of clinical diagnosis and efficacy evaluation in patients with upper limb spasm after stroke.
