The tumor microenvironment (TME) is the cellular milieu in which tumor cells thrive, comprising interacting cells and associated factors that form a complex network of interactions, directly or indirectly influencing the initiation, progression, and metastasis of lung cancer. Through TCM pattern identification, it has been observed thatphlegm-pathogen is closely associated with disorder in the inflammatory-metabolic-immune microenvironments of lung cancer. This involves three key pathological mechanisms: "phlegm-stasis complicated by toxin, qi deficiency with exuberant phlegm, and phlegm-pathogen impairing healthy qi". Molecular mechanism studies have revealed that phlegm-resolving agents can extensively modulate multiple targets or pathways, thereby remodeling the inflammatory-metabolic-immune microenvironments of lung cancer. Consequently, a comprehensive therapeutic strategy integrating "resolving phlegm, dispelling stasis, and detoxifying; supplementing qi, warming yang, and resolving phlegm; and reinforcing healthy qi, tonifying the lung, and eliminating phlegm" is essential to reshape the lung cancer TME and enhance antitumor efficacy.

Pseudorabies (PR) is an infectious disease caused by the pseudorabies virus (PRV), affecting various domesticated and wild animals. Since pigs are the only natural hosts of PRV, PR poses a serious threat to the pig farming industry. Currently, PR is primarily prevented through vaccination with inactivated vaccines or genetically modified attenuated live vaccines. Developing safe and effective genetically engineered vaccines would facilitate the eradication and control of PR. In this study, the PRV vaccine strain Bartha-K61 was used as the reference strain. The gB protein was expressed via the baculovirus-insect cell expression system. Non-denaturing gel electrophoresis confirmed that the gB protein could form a trimeric structure. The purified gB protein was used to immunize mice, and the immune effect was evaluated by a challenge test. The results showed that the gB antigen induced a strong immune response in mice, with the serum-neutralizing antibody titer above 1:70. The lymphocyte stimulation index reached more than 1.29, and the level of (interferon gamma, IFN-γ) release was higher than 100 pg/mL. After immunization, mice were challenged with the virus at a dose of 10⁴ TCID₅₀/mL, 200 μL per mouse, and the clinical protection rate was 100%. Immunohistochemistry, histopathological section, and tissue viral load results showed that the pathological damage and viral load in the gB-immunized group were significantly lower than those in the PBS group. In summary, the gB protein obtained in this study induced strong humoral and cellular immune responses in mice, laying a foundation for developing a recombinant gB protein subunit vaccine.

Objective To make clear the arsenic distribution in drinking water sources in Hubei Province, make provincial distribution map of high-arsenic water and provide scientific basis for formulating refined measures to prevent and control arsenic poisoning of drinking water type in Hubei Province. Methods In 103 counties of Hubei Province, residents were sampled according to different water supplies (centralized water supply, small centralized water supply in rural areas and decentralized water supply). One water sample was collected from source water and tap water in centralized water supply system and at least 3 samples were collected from decentralized water supply system in a village. Water iodine content was tested using atomic fluorescence spectrometry and a distribution map of high-arsenic water at county level was drawn using ArcGIS 10.2. Results Totally 38 292 water samples were collected. The water-arsenic-concentration median was less than 1.00 μg/L. The high-arsenic water detection rate in urban centralized water supply was 3.7%(80/2 176);which were all 0.1%(4/4 304,30/31 812) in small centralized water supply in rural areas and decentralized water supply. The high-arsenic water sources from centralized water supplies were distributed centrally in the south, the central and the east of Hubei Province and those from dispersed water supplies were distributed dispersedly in the south, the central and the east of Hubei Province.Conclusions There are still some dispersed water supplies with very high arsenic concentration in Hubei Province, which should be included to change the water area as soon as possible. Moreover, high arsenic water samples are found from centralized water supplies, which means the water treatment process should be upgraded or water resources should be changed.

Objective To make clear the fluorine content distribution in drinking water of residents in Hubei Province,draw a provincial distribution map of high-fluorine water and provide scientific basis for formulating refined prevention and control measures of drinking water type fluorosis in Hubei Province.Methods In 116 counties of Hubei Province,including development zones,scenic zones and farmlands,drinking water of residents was sampled according to different water supplies (centralized water supply,small centralized water supply in rual areas and decentralized water supply) from 2013 to 2015.For a centralized water supply,one sample was collected from the source water and the tap water each and at least 3 samples were collected for decentralized water supply in a village.Selective electrode method was used to detect the water fluorine content and ArcGIS 10.2 was used to draw distribution map of high-fluorine water at county level.Results A total of 38 284 water samples were collected,the median of fluorine content was 0.21 mg/L.The highest detective rate of all types of water supply with high fluorine content was pressure water well (64/100,64.0％) and high-fluorine water sample was not found in the reservoir.The high-fluorine water sources from centralized water supplies were distributed dispersedly in the north-west and the east of Hubei Province and those from decentralized water supplies were distributed dispersedly in the middle-north and the east of Hubei Province.Conclusions Fluorine concentration in drinking water is generally low.However,there are still some high-fluorine water supplies which should be reported to Hubei Provincial Water Resources Department as soon as possible.Moreover,there is a phenomenon of fluorine rebounce in the water reduction project,and managements of those projects should be strengthened.

Objective To explore value of detecting fetal thymus size with the thymic-thoracic ratio (TT-ratio).Methods Prenatal ultrasonography examinations were performed on totally 317 normal singleton healthy pregnancies from 18 to 39 gestational weeks.The normal thymus of fetus were observed on the three-vessel-trachea (3VT) view.The anteroposterior diameter of the thymus (T1) was measured between the anterior border of the aortic arch and posterior border of sternum.The intrathoracic mediastinal diameter (T2) was measured between the anterior border of thoracic vertebral body and posterior border of sternum.The TT-ratio was then calculated as the ratio of T1 to T2.Scatter plot between TT-ratio and gestational age was drawn.And the Spearman regression analysis was performed.Results The thymus of fetus was shown as an irregular homogenous structure in the anterior mediastinum on the 3VT view.The mean TT-ratio was 0.45± 0.03.There was no correlation between TT-ratio and gestation (rs =0.06,P=0.29).Conclusion Prenatal ultrasound can display the thymus obviously.TT-ratio could be applied to assess the fetal thymus size,which can provides clinical basis for the detection of absent or hypoplastic thymus in fetus.
