Stiff-person syndrome （SPS） is a rare autoimmune neurological disorder with atypical symptoms and signs，which often leads to missed diagnosis or misdiagnosis，resulting in delayed treatment. This article reports a female patient，aged 72 years，who was diagnosed with SPS，and her symptoms were improved after symptomatic treatment including intravenous injection of human immunoglobulin，corticosteroids，clonazepam，and baclofen. It is suggested that early diagnosis and timely treatment can improve the quality of life and prognosis of SPS patients with positive anti-amphiphysin antibodies.

ObjectiveTo investigate the effect and mechanism of Sishenwan in restoring the intestinal barrier function in the rat model of diarrhea-predominant irritable bowel syndrome （IBS-D） due to spleen-kidney Yang deficiency based on intestinal flora and short-chain fatty acids. MethodsAfter the delivery of 10 SPF-grade pregnant rats， 4 male suckling rats were kept in each litter for the experiment. The male suckling rats were randomly allocated into blank， model， low-dose （3.51 g·kg^-1） Sishenwan， high-dose （7.02 g·kg^-1） Sishenwan， and Peifeikang （0.54 g·kg^-1） groups， with 8 rats in each group. The blank group was fed conventionally， and the other groups were subjected to mother-child separation and Sennae Folium gavage （1 g·mL^-1， 10 mL·kg^-1） for the modeling of IBS-D due to spleen-kidney Yang deficiency. After the modeling was completed， the rats in Sishenwan groups were administrated with the corresponding dose of Sishenwan decoction by gavage， and the Peifeikang group with bifidobacterium triple live powder+normal saline suspension. The blank and model groups were treated with an equal volume of normal saline by gavage. The general conditions and fecal characteristics of rats were observed. After 2 weeks of administration， the rats were anesthetized for sample collection. The pathological changes of the colon tissue in rats were observed by hematoxylin-eosin staining. Enzyme-linked immunosorbent assay was employed to measure the levels of transforming growth factor-beta （TGF-β）， interleukin-10 （IL-10）， and interleukin-22 （IL-22）. Immumohistochemical staining （IHC） was performed to detect the positive expression of zonula occludens-1 （ZO-1） and occludin in the colon tissue. Western blot was employed to determine the protein levels of ZO-1 and occludin in the colon tissue of rats， and 16S rRNA gene sequencing was performed for intestinal flora. Gas chromatography-mass spectrometry was employed to determine the content of short-chain fatty acids （SCFAs） in the cecum contents of rats. ResultsThe colon tissue in the blank group presented a clear structure， neat glands， and no inflammatory cell infiltration. In the model group， the colon tissue showcased a disorganized structure， irregular arrangement of glands， and inflammatory cell infiltration. Compared with the model group， the low-dose and high-dose Sishenwan groups and the Peifeikang group exhibited an intact colon tissue structure， regular arrangement of glands， and reduced inflammatory cell infiltration. Compared with the blank group， the modeling lowered the levels of TGF-β， IL-10， and IL-22 in the serum （P<0.01）， down-regulated the protein levels of ZO-1 and occludin in the colon tissue （P<0.01）， and decreased the content of acetic acid and propionic acid and increased the content of butyric acid in cecum contents （P<0.05）. Compared with the model group， low-dose and high-dose Sishenwan raised the levels of TGF-β， IL-10， and IL-22 in the serum （P<0.05， P<0.01）， and Peifeikang elevated the levels of TGF-β and IL-10 in the serum （P<0.01）. High-dose Sishenwan and Peifeikang up-regulated the protein levels of ZO-1 and occludin （P<0.05， P<0.01）， increased the content of acetic acid and propionic acid in cecum contents （P<0.05）， and decreased the content of butyric acid （P<0.05）. The 16S rRNA gene sequencing results showed that the intestinal flora structure of the model group changed compared with that of the blank group. Compared with the model group， Sishenwan and Peifeikang increased the relative abundance of Lachnospiraceae， Muribaculaceae， Akkermansiaceae， Ligilactobacillus， UBA3282， Akkermansia， and Corynebacterium while reducing the relative abundance of Oscillospiraceae， Desulfovibrionaceae， Lactobacillus， Romboutsia， and Desulfovibrio. They can restore the intestinal flora structure similar to that in the blank group. ConclusionSishenwan can alleviate diarrhea symptoms and colonic mucosal inflammation， increase the expression of tight junction proteins in the colonic mucosa， and strengthen the intestinal barrier in IBS-D rats with the syndrome of spleen-kidney Yang deficiency. The mechanism of action may be related to optimizing the structure and balance of intestinal flora and regulating the SCFAs， and the effect of high-dose Sishenwan is obvious.

Objective:To investigate the expression of the proinflammatory factor IL-18-mediated NOD-like receptor thermal protein domain associated protein 3/nuclear factor κB(NLRP3/NF-κB)signaling pathway in penile tissues of rats with high-fat diet-in-duced erectile dysfunction(ED),and to explore the intervention effect of sildenafil.Methods:Fifty-five sexually normal male SD rats were randomly divided into 10 cases as the normal control group,and the rest of the rats were fed with high-fat chow to establish the ED rat model,and the successfully screened ED rats were randomly divided into the ED group,the Sil group,the IL-18 group,and the IL-18+Sil group,with 8 rats in each group.Following 14 days of nonstop treatment,the morphological alterations in the penile tis-sue were observed by HE staining.Using immunohistochemistry,the amount and distribution of NF-κB p65 and Adropin in penile tis-sues were found.RT-qPCR was used to identify the expression of NLRP3 and NF-κB p65 mRNA in penile tissues.Western blot exami-nation showed the expression of the proteins NLRP3,pro-IL-18,p-NF-κB p65,NF-κB p65,and Adropin in penile tissues.Results:The ED group showed altered penis tissue morphology,destroyed muscle fibers,enlarged sinus cavity,increased mRNA and protein expressions of NLRP3,p-NF-κB p65/NF-κB p65,and pro-IL-18(all P<0.05),and decreased Adropin protein expression(P<0.05).While the protein expression of Adropin was increased(P<0.05),the mRNA and protein expressions of NLRP3,p-NF-κB p65/NF-κB p65,and pro-IL-18 in the penis tissues were decreased(all P<0.05)when compared to the ED group.The muscle fibers and sinus cav-ities of the penis were recovered to varying degrees in the Sil group.The IL-18 group experienced the destruction of muscle fibers,an enlargement of the sinus cavity,an increase in the mRNA and protein expressions of NLRP3,p-NF-κB p65/NF-κB p65,and pro-IL-18 in the penile tissues(all P<0.05),as well as a decrease in the protein expression of Adropin(P<0.05).The rat penile tissues in the IL-18+Sil group showed variable degrees of recovery in the muscle fibers and sinus cavities when compared to the IL-18 group.Ad-ditionally,there was a drop(all P<0.05)in the expressions of NLRP3,pro-IL-18 m RNA and protein,p-NF-κB p65/NF-κB p65,and p-NF-κB p65 in the penile tissues.The expression of the Adropin protein was elevated(P<0.05).Conclusion:Significant changes have been observed in the NLRP3/NF-κB signaling pathway,which is regulated by IL-18,in the hyperlipidemia ED rat model.In ED rats,sildenafil can increase erectile function by promoting the production of Adropin and blocking the activation of this pathway.

Objective:To investigate the clinical efficacy of acupuncture aimed at awakening the mind and opening the orifices, when combined with a qi-tonifying and blood-circulating decoction, in the treatment of post-stroke dysphagia due to qi deficiency and blood stasis. Methods:A randomized controlled study was conducted involving 86 patients with post-stroke dysphagia due to qi deficiency and blood stasis who were admitted to the Department of Acupuncture and Moxibustion at Yan'an Hospital of Traditional Chinese Medicine from January 2020 to March 2023. The patients were randomly divided into a control group and a treatment group, with 43 cases in each group, using a random number table method. The control group received conventional treatment, while the treatment group received acupuncture aimed at awakening the mind and opening the orifices combined with a qi-tonifying and blood-circulating decoction. Both groups were treated for 1 month. Clinical efficacy, swallowing function, serological indicators, floating index, and quality of life were compared between the two groups. Results:After treatment, the Standardized Swallowing Assessment score in the treatment group was (18.23 ± 2.04) points, which was significantly lower than that in the control group [(22.52 ± 4.38) points, t = 5.82, P < 0.05]. The Water-Swallowing test score in the treatment group was (2.77 ± 0.55) points, which was significantly higher than that in the control group [(2.00 ± 0.42) points, t = 7.30, P < 0.05]. The level of superoxide dismutase in the treatment group was (147.54 ± 21.03) kU/L, which was significantly higher than that in the control group [(128.31 ± 18.54) kU/L, t = 4.50, P < 0.05]. The Pulsatility Index in the treatment group was (0.72 ± 0.25), which was significantly lower than that in the control group [(0.83 ± 0.24), t = 0.74, P < 0.05]. The cerebral vascular reserve in the treatment group was (42.28 ± 5.69)%, which was significantly higher than that in the control group [(35.45 ± 4.31)%, t = 2.03, P < 0.05]. The Swallowing Quality-of-Life Questionnaire score in the treatment group was (76.33 ± 11.54) points, which was significantly higher than that in the control group [(68.02 ± 12.16) points, t = 3.25, P < 0.05]. The response rate in the treatment group was 97.67% (42/43), which was significantly higher than that in the control group [86.05% (37/43), χ2 = 3.89, P < 0.05]. Conclusions:The use of acupuncture for awakening the mind and opening the orifices, combined with a qi-tonifying and blood-circulating decoction, can significantly enhance clinical efficacy and improve the quality of life for patients with post-stroke dysphagia due to qi deficiency and blood stasis syndrome compared with conventional treatment.

Objective:To observe the effect of ankle joint proprioception training on ankle joint proprioception, balance and gait in patients with thalamic infarction.Methods:Fifty-six patients with thalamic infarction were divided into a control group and a treatment group, each of 28, using a random number table. Both groups were given conventional lower limb rehabilitation training, but the treatment group was additionally provided with ankle joint proprioception training. Before and after 4 weeks of the treatment, the Tecnobody proprioception testing system was used to determine the average trajectory error rate (ATE) and the time taken in the test. The Berg Balance Scale (BBS) and a balance tester were used to assess balance. A gait analyzer was used to collect spatial-temporal measures of the patients′ walking, including the stride amplitude, stride rate, the proportion of the time spent in the swing phase, and foot dorsiflexion and plantarflexion angles.Results:After the treatment, the time used, ATE, ankle proprioception, BBS scores, static balance test scores, stability limits, stride length, stride rate, swing phase time percentage, and foot dorsiflexion and plantarflexion angles had improved in both groups compared with before the treatment ( P≤0.05). Compared with the control group, the treatment group had a smaller average ATE, spent less time on the ankle proprioception test, had higher BBS scores, had lower scores on the static balance test, had larger limits of stability, took longer strides at a faster rate, and spent a greater percentage of time in the swing phase. That group also showed greater ankle dorsiflexion and plantarflexion on average ( P≤0.05). ATE difference of the affected lower limb and the time to complete the ankle proprioception test were positively correlated with the gap in the static balance ability test, and negatively correlated with the gaps in the BBS score, the limits of stability, stride length, stride rate, and the time share of the swing phase, as well as the dorsiflexion and plantarflexion angles of the foot. Conclusions:Ankle proprioception training, in addition to effectively improving ankle proprioception, can improve the balance and gait of persons with thalamic infarction. It is worthy of clinical application and promotion.
