Objective:To investigate the clinicopathological characteristics of acidophil stem cell pituitary neuroendocrine tumors (PitNET)/adenoma.Methods:Five cases of acidophil stem cell PitNET/adenoma were diagnosed between May 2022 and July 2023 at the Second Hospital of Hebei Medical University, Shijiazhuang, China. The clinicopathological features of the tumor were analyzed by using histology, immunohistochemistry, and electron microscopy. The relevant literature was reviewed.Results:There were 1 male and 4 females, aged from 23 to 69 years. Patient 3 was 55 years old at the time of diagnosis and first surgery, and relapsed 5 years later. The patients′ median age was 32 years. Patients 1 and 5 showed elevated blood prolactin, with various degrees of hormonal symptoms except Patient 3, who showed only tumor compression symptoms. Imaging studies showed that all cases involved the sellar floor. The tumors of Patients 1, 2 and 5 were closely related to the cavernous sinus segment of the internal carotid artery. The tumors exhibited a diffuse growth pattern with chromophobic to slightly acidophilic cytoplasm. A few of tumor cells showed chromophobic cytoplasm. The nucleoli were conspicuous. Intranuclear inclusion bodies and variably-sized clear vacuoles were observed occasionally. Under electron microscope, marked mitochondrial abnormalities were observed, including increased mitochondria number, expanded hypertrophy, and absence of mitochondrial ridge fracture. Some mitochondrial matrices were dense, while some were vacuolated.Conclusions:Acidophil stem cell PitNET/adenoma is a rare type of pituitary adenomas/PitNETs. It often has a more clinically aggressive manner with immature cells, diffuse expression of PIT1, prolactin, and varying degrees of growth hormone expression. Because of the obvious diversity of their clinical hormone status and hormone immune expression, the diagnosis of this type tumor is still a challenge.

During the Jin dynasty,the two major academic schools of Hejian and Yishui emerged in northern China.At this time,the Song dynasty migrated southward,accompanied by the southward movement of the Han ethnic culture and economic center.The dissemination of medicine also showed a trend of spreading from the north to the south.The late Yuan dynasty was an important period for the academic dissemination of the Yishui school to the south.On the one hand,ZHU Danxi,GE Yinglei,HUA Shou,and other clinicians studied the academic works of LI Dongyuan,comprehended his academic ideas,and further disseminated them through their disciples and Confucian scholars.On the other hand,academic works such as Jisheng Bacui and Weisheng Baojian carrying the study of Yishui were published in the south,playing an essential role in disseminating Yishui's study in the south.The dissemination of Yishui's learning to the south adopted a combination of book learning and mentorship,effectively breaking down the academic barriers between the Hejian and Yishui schools.The network formed by the interaction between medical scholars and Confucian scholars was an essential medium for academic dissemination.The study of Yishui was transmitted to the south and integrated with the original spleen and stomach theory in the south,promoting the further development of traditional Chinese medicine spleen and stomach theory.

Objective To explore the clinical curative effect of theTaohong-Siwu decoction combined with manipulation in the treatment of the acute phase of lumbar disc herniation (LDH) and its effect on serum inflammatory factors.Methods According to the random number table method, 102 patients with the acute phase of LDH were divided into control group and research group from May 2014 to September 2016, 51 cases in each group. Patients in control group were treated by traction and non-steroidal anti-inflammatory drug for a month, while patients in research group were treated by manipulation combined withTaohong-Siwu decoction for a month. After treatment, the overall efficacy was observed. The Visual analogous scale (VAS) and JOA scores were recorded before and after the treatment. The IL-1β, IL-6 and TNF-α levels of inflammatory factors were detected by enzyme-linked immunosorbent assay.Results The total effective rate of patients in research roup was significantly higher than that of the control group [90.20％ (46/51)vs. 43.14％ (22/51),χ2=19.329, P=0.006]. After treatment, the VAS scores of patients in both groups were significantly decreased, and JOA score increased markedly, which the differences were statistically significant (Ps<0.05). After treatment, the VAS score of research group was significantly lower than the control group (4.26 ± 0.56vs. 5.13 ± 0.87;t=4.843, P=0.027), and JOA score was significantly higher than the control group (18.42 ± 3.92vs.17.33 ± 4.21;t=5.127, P=0.022). After treatment, the IL-1β, IL-6 and TNF-α levels of of patients in the research group were significantly lower than those of the control group (0.57 ± 0.11μg/Lvs. 0.90 ± 0.13μg/L, 112.26 ± 15.17μg/Lvs. 130.38 ± 18.29μg/L, 2.01 ± 0.34μg/Lvs. 2.37 ± 0.51μg/L;t=5.429, 6.317, 5.011,P<0.05). ConclusionsThe Taohong-Siwu decoction combined with manipulation on treatment of the acute phase of LDH was effective. The combined therapy can improve the VAS score and JOA score, and reduce the levels of inflammatory cytokines.
