Andrographis paniculata is a traditional Chinese herbal medicine with a wide cultivation in south China. The market demand has been increasing steadily in recent years. However, there are problems such as disordered production, pesticide residues and heavy metal content in the process of Andrographis paniculata production. Pollution- free cultivation is an effective strategy to solve this problem, and it is also the development direction of the Chinese herbal medicine planting industry at this stage. In order to guide the cultivation of pollution-free and high-quality Andrographis paniculata, this study established a pollution- free fine cultivation technology system of Andrographis paniculata including precise cultivation and site selection. In addition, soil improvement, scientific pollution-free planting mode and high- efficiency integrated pest control technology help solve problems such as pesticide residues and heavy metal content. This paper provides a reference for the pollution-free and fine cultivation of Andrographis paniculata.

Hypersplenism is an important complication of cirrhotic portal hypertension, and splenectomy is an important means to treat hypersplenism in cirrhosis. It is realized that hypersplenism played a pathological role in the course of cirrhosis. This article analyzes and compares the changes in the condition of patients with cirrhosis between splenectomy with and without hyperfunction, and comprehensively discusses the pathological role and mechanism of hypersplenism in the course of cirrhosis, in order to strengthen the clinical prevention and treatment of hypersplenism in cirrhosis and to better improve the condition and prognosis of patients with cirrhosis.

FYVE and coiled-coil domain containing 1(FYCO1) is an adaptor of cellular autophagy which has RUN domain, coiled coil domain, FYVE domain, GOLD domain and LIR domain.FYCO1 protein is widely expressed and mainly interacts with Atg8 family proteins, microtubule-based kinesins, phosphatidylinositol-3-phosphate (PI3P). The FYCO1 protein involved in the movement of kinesins along microtubules and the microtubule plus end-directed transport of autophagy vesicles and related to the development and transparency maintenance of human lens.

Objective To observe the clinical curative effect of unilateral biportal endoscopy(UBE)in the treatment of extreme lateral lumbar disc herniation(ELLDH).Methods From June 2019 to June 2022,25 patients with ELLDH were treated with UBE-guided discectomy,including 16 males and 9 females.The age ranged from 26 to 62 years with a mean of(53.67±17.45)years.History ranged from 3 d to 10 years.There were 9 cases of internal foraminal type(type Ⅰ),13 cases of external foraminal type(type Ⅱ)and 3 case of mixed type(type Ⅲ).There were 8 cases of L4/5 space and 17 cases of L5/S1 space.All the patients underwent anterior and lateral lumbar X-rays,CT and MRI scans before surgery.The visual analogue scale(VAS)pain score and Oswestry disability index(ODI)assessed lower limb and lower back pain and functional recovery before surgery and at 3 d and 3 months after surgery,respectively.Macnab criteria evaluated the immediate surgical outcome.Results The UBE technique was used to treat ELLDH.The operative time was(79.79±23.97)min,the intraoperative bleeding volume was 40~80 mL,with an average of(55.80±10.74)mL.Follow-up time was(7.02±4.26)months.Preoperative VAS of lower limb was(7.04±0.92),lower back VAS was(3.49±1.52),ODI was(35.03±2.97)%.Compared with the preoperative results,the lower limb VAS was(2.17±0.61),lower back VAS was(1.48±0.43),and ODI was(18.77±3.15)%on day 3 after surgery,lower limb VAS was(1.38±0.65),lower back VAS was(1.03±0.48)and ODI was(6.05±1.80)%on the 3 months after surgery were improved(P<0.05).The excellent and good rate was 96.0%(excellent 20,good 4,fair 1),and no obvious complications were observed during the follow-up.Conclusion UBE is effective,with little trauma,clear intraoperative visual field,good intraoperative experience,and less traumatic and safe in the treatment of ELLDH.
