The study explores the current situation of the burden of chronic poor patients and the core essence of the accurate health poverty alleviation policy.More specifically, it aims to analyze the existing problems and practical dilemmas in the implementation of the accurate health poverty alleviation policy, and conveying recommendations for the policy formulation.The analysis shows that the problems in the implementation of the accurate health poverty alleviation policy in China are: the empowerment of the poor population is not accurate;the dynamic management and assessment mechanism is not accurate;and the allocation of poverty alleviation resources is not rational.In view of these problems, the following suggestions were put forward: the establishment of a multi-dimensional poverty identification system, the improvement of poor households through building up their card information;improve the accurate poverty alleviation dynamic supervision and assessment system;rational allocation of poverty alleviation resources, promote the supporting policies and institutional innovation.

OBJECTIVE To investigate the effect of sustained-release glucocorticoid stent on nasal mucosal eosinophil(Eos)%and nasal microbiota in patients undergoing eosinophilic chronic sinusitis with nasal polyps(ECRSwNP)surgery.METHODS A total of 104 patients with ECRSwNP admitted to Qianjiang Central Hospital from August 2020 to August 2022 were selected.The patients were randomly divided into an observation group and a control group,with 52 patients in each group.During nasal endoscopic surgery,slow-release glucocorticoid stents were implanted or not.The hospital stay,nasal ventilation recovery time,and total effective rate of treatment were compared between the two groups.The nasal mucosal Eos%and nasal microbiota were compared between the two groups before and one month after surgery.The Lund-Kennedy score of nasal endoscopy,SNOT-22 outcome tests,and visual analogue scale(VAS)scores were compared between the two groups before and three months after surgery.The intervention rate and frontal sinus patency rate at 3 months after surgery in two groups.RESULTS The hospitalization time and nasal ventilation recovery time of the observation group were significantly lower than those of the control group(P<0.05).The total effective rate of the observation group treatment was 92.31%(48/52),which was significantly higher than that of the control group 76.92%(40/52)(P<0.05).After surgery,the Eos%of the nasal mucosa in both groups significantly decreased compared to before surgery(P<0.05),and the observation group was lower than the control group(P<0.05).There was no statistically significant difference in Shannon index and Chaol index between the two groups before surgery(P>0.05);The Shannon index in the control group decreased significantly after surgery(P<0.05),while the Chaol index increased significantly after surgery(P<0.05);There was no significant difference in postoperative Shannon index and Chaol index between the observation group and preoperative group(P>0.05).After surgery,the Lund-Kennedy score,SNOT-22 score,and VAS score in both groups were significantly lower than before(P<0.05),and the observation group was lower than the control group(P<0.05).The intervention rate of the observation group was significantly lower than that of the control group(P<0.05),and the frontal sinus patency rate was significantly higher than that of the control group(P<0.05).CONCLUSION The sustained-release glucocorticoid stent is beneficial for the epithelialization of the surgical cavity in ECRSwNP patients,reducing mucosal Eos%,improving clinical symptoms,ensuring smooth frontal sinus drainage,reducing postoperative intervention rates,and having no significant impact on nasal microbiota.

BACKGROUNDLymphangioleiomyomatosis (LAM) is a rare disease that predominantly affects young females. It is considered as an "orphan" life-threatening disease of unknown etiology, with uncertain clinical prognosis, and no effective treatment. LAM can arise sporadically or in association with tuberous sclerosis complex (TSC), an autosomal inherited syndrome characterized by hamartoma-like tumor growth and pathologic features that are distinct from manifestations of pulmonary LAM. The clinical course of LAM is characterized by progressive dyspnea on exertion, recurrent pneumothorax, and chylous fluid collections.

METHODSFourteen cases of LAM from Zhongshan Hospital, Fudan University are reviewed, twelve were confirmed by lung biopsy, one by retroperitoneal lymphangioleiomyoma resection, and one by autopsy.

RESULTSAll 14 patients were women, aged 18 to 69 years (mean 43.3 years, median 46.5 years). Haemoptysis (57.1%) and chylothorax (35.7%) were more frequent than those described in previous case series. Extrapulmonary findings such as renal angiomyolipoma (AML), enlarged abdominal lymph nodes, liver AML and retroperitoneal lymphangioleiomyoma were seen in 21.4%, 14.3%, 7.14% and 7.14% in 14 cases respectively, which is remarkably lower than in the previously reported. Abnormal smooth muscle cells (LAM cells) were found to line the airways, bronchioles, lymphatics and blood vessels leading to airflow obstruction and replacement of the lung parenchyma by cysts. There were some surprises in the autopsy case as several LAM cell emboli were found in the veins of mediastinum lymph nodes; LAM cells were found to be disseminated in soft tissues adjacent to the ilium.

CONCLUSIONSWomen with unexplained recurrent pneumothorax, tuberous sclerosis, or a diagnosis of primary spontaneous pneumothorax or emphysema in the setting of limited or absent tobacco use should undergo high-resolution computed tomography (HRCT) scan screening for LAM. Routine abdominal and pelvic imaging examinations should be performed to detect extrapulmonary involvement. The autopsy studies histologically suggested that LAM could be a multisystemic disease and LAM cells might possess metastatic potential.
