Sishen Pills is a classic prescription for the treatment of spleen and kidney diarrhea,which has the effect of warming the kidney and the spleen,astringent intestine and antidiarrheal.In modern clinical application,the modified prescriptions based on Sishen Pills,combined with other treatments of TCM and integrated traditional Chinese and Western medicine are often used to treat ulcerative colitis with spleen-kidney yang deficiency syndrome,and the curative effect is remarkable.Experimental pharmacological studies have shown that Sishen Pills may achieve the purpose of ulcerative colitis by regulating the expression of related signaling pathway proteins,regulating inflammatory factors,inhibiting inflammatory response,regulating autophagy,regulating intestinal flora,improving intestinal mucosal permeability,repairing intestinal mucosal barrier,regulating cellular energy metabolism,anti-oxidative stress,regulating cellular immune function,etc.In this article,the research status of Sishen Pills in the treatment of ulcerative colitis was sorted out and summarized,in order to provide reference for further study of its mechanism and clinical application.

Pathological mechanism of ulcerative colitis(UC)is not fully clear,which may be the result of Th17/Treg immune imbalance and the interaction of multiple complex factors.Numerous studies have found that classical TCM prescriptions,experienced formulas and TCM active components could regulate Th17/Treg balance by intervening in cytokines,transcription factors,and signaling pathways,restore intestinal mucosal immune function,suppress intestinal mucosal inflammatory response,and repair intestinal mucosal barrier damage.Based on the research status of UC,Th17/Treg balance and TCM treatment,this article reviewed the relationship between Th17/Treg balance and UC,and explained the key role of Th17/Treg balance in the occurrence and development of UC.At the same time,the Chinese materia medica targeting to regulate the balance of Th17/Treg in the treatment of UC in recent years was summarized,in order to provide reference for the treatment of UC.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To investigate the construction effects of the graduate biochemistry technology courses based on the outcome-based education (OBE) concept, analyze the technical needs of graduate students, and further integrate and optimize the teaching methods.Methods:A self-compiled questionnaire with good reliability and validity was used to conduct an overall sampling survey on the graduate students who took the elective courses in Batch 2021 in a medical college in Shanghai. Excel and GraphPad Prism software were used for data analysis.Results:According to this survey, the courses gain good effects in terms of teaching framework, course facilities, teaching forms, teaching contents and comprehensive evaluation of teaching. A total of 112 students (95.2%) thought that the course was very helpful to the expansion of experimental technology and experimental operation ability. However, there were still some teaching needs, such as expanding the types of experiments and increasing experimental operations.Conclusions:Under the guidance of OBE concept, the construction of the graduate biochemistry technology courses has gradually achieved good results.

Ureteral stenosis and bladder contracture after radiotherapy for cervical cancer are challenging issues in urology. Ileal ureteroplasty combined with ileal bladder augmentation is a potential method to improve hydronephrosis and voiding function of patients, however, the surgical procedure is complex, with high surgical risks and numerous intraoperative and postoperative complications, which have hindered the widespread application of this surgical technique. This article introduces our hospital's experience through a typical surgical case. During the surgery, ileal substitution for bilateral ureters was performed in combination with ileal " N-shaped" augmentation. Two weeks after the surgery, the single-J stent was removed, and the urinary catheter was removed three weeks after the surgery. The patient achieved voluntary urination control with smooth voiding. Follow-up examinations at 3 months and 18 months postoperatively showed no hydronephrosis in the bilateral ureters, normal renal function, and a significantly expanded bladder capacity.

ObjectiveTo explore the effect of Jianpi Yichang power on the nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3） inflammasome signaling pathway in a rat model of ulcerative colitis （UC）. MethodSixty Sprague-Dawley rats were randomly divided into a normal group （n=10） and an experimental group （n=50）. The experimental group received 5% dextran sulfate sodium （DSS） solution freely for 7 days to induce UC， and then they were further randomly divided into model group， sulfasalazine （0.3 g·kg^-1） group， and high-， medium-， and low-dose Jianpi Yichang power groups （54.4， 27.2， 13.6 g·kg^-1） for continuous treatment of 14 days. The general condition of the rats was observed and recorded daily， and the disease activity index （DAI） was scored before and after treatment. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of interleukin-1β （IL-1β） and interleukin-18 （IL-18） in the serum of rats in each group. Hematoxylin-eosin （HE） staining was performed to observe the histopathological changes in the colon tissue. Immunohistochemistry， Western blot， and Real-time polymerase chain reaction （Real-time PCR） were used to detect the positive protein expression， protein expression， and mRNA expression of NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， and cysteine aspartate-special proteases-1（Caspase-1） in the colon tissue. ResultCompared with the condition in the normal group， the general condition of rats in the model group was relatively poor， with increased DAI scores （P<0.01）， pathological changes in the colon， increased levels of IL-1β and IL-18 in the serum （P<0.01）， and enhanced positive protein expression， protein expression， and mRNA expression of NLRP3， ASC， and Caspase-1 in the colon tissue （P<0.01）. Compared with the condition in the model group， the general condition of rats in the Jianpi Yichang power groups at various doses improved significantly， with reduced DAI scores （P<0.05， P<0.01）， alleviated pathological changes in the colon as revealed by HE staining， and reduced protein expression levels of NLRP3 and Caspase-1 in the colon tissue （P<0.05， P<0.01）. The serum levels of IL-1β and IL-18， and ASC protein expression in the colon， as well as the mRNA expression levels of NLRP3， ASC， and Caspase-1， decreased in the high- and medium-dose Jianpi Yichang power groups （P<0.05， P<0.01）. The positive protein expression levels of NLRP3， ASC， and Caspase-1 were reduced in the high-dose Jianpi Yichang power group （P<0.01）. The positive protein expression levels of ASC and Caspase-1 were reduced in the medium-dose Jianpi Yichang power group （P<0.05）. The mRNA expression level of ASC was reduced in the low-dose Jianpi Yichang power group （P<0.05）. ConclusionJianpi Yichang power can reduce colon immune inflammatory damage by regulating the NLRP3 inflammasome signaling pathway， thereby exerting a role in treating UC.

Objective:To investigate the predictive value of stone composition prediction method based on dual-source stone energy spectrum CT for uric acid stones.Methods:The clinical data of 204 patients with urinary stones, 159 males and 45 females, admitted to Shanghai Sixth People's Hospital from July 2020 to July 2022 were retrospectively analyzed. The average age was (50.7±14.3) years. There were 187 cases of upper urinary tract (kidney, ureter) stones and 17 cases of lower urinary tract (bladder, urethra) stones. All patients underwent preoperative dual-source stone energy spectroscopy CT, measuring CT values at 150 kV and 100 kV, respectively, and the calculated dual energy ratio (Ratio) was used to predict stone composition. Of the 204 cases in this group, 33 cases underwent percutaneous nephrolithotomy and 171 cases underwent ureteroscopic lithotripsy. Postoperative stone specimens were analyzed for stone composition by infrared spectroscopy. Subject work characteristic (ROC) curves were used to analyze the efficacy of preoperative dual-source stone energy spectrum CT to predict uric acid stones.Results:In 204 patients, preoperative CT predicted 28 cases of uric acid stones and 176 cases of non-uric acid stones, including 136 cases of calcium oxalate stones, 38 cases of hydroxyapatite, and 2 cases of cystine stones. Postoperative IR spectral analysis detected 26 cases of uric acid stones and 178 cases of non-uric acid stones, including 129 cases of calcium oxalate stones, 47 cases of hydroxyapatite, and 2 cases of cystine stones. Compared with the preoperative CT results, there were 2 false positives and no false negatives in the classification of uric acid stones. The ROC curve showed that the sensitivity of the CT value for predicting uric acid stones at 100 kV was 96.2%, the specificity was 99.5%, and the area under the ROC curve (AUC) was 0.995, with the best prediction value of 620 HU.The sensitivity of the CT value for predicting uric acid stones at 150 kV was 96.2%, specificity was 85.5%, AUC was 0.916, and the best predictive value was 597.5 HU. The sensitivity of using Ratio values for predicting uric acid stones was 100.0%, specificity was 97.9%, AUC was 0.996, and the best predictive value was 1.14. The CT values for uric acid stones at 100 kV and 150 kV were (558.58±77.07) HU and (521.12±83.54) HU, CT values for calcium oxalate stones were (1 335.26±301.82) HU and (878.21±200.21) HU, CT values for hydroxyapatite were (1 104.09±203.61) HU and (710.38±178.44) HU, respectively.The CT values of cystine stones were (684.5±67.18) HU and (573.5±67.10) HU, respectively, and the differences between uric acid stones and other components were statistically significant ( P<0.01). The Ratio values of uric acid stones, calcium oxalate stones, hydroxyapatite, and cystine stones were 1.08±0.06, 1.52±0.08, 1.62±0.40, and 1.19±0.02, respectively, and the differences were statistically significant ( P<0.01) when comparing uric acid stones with other components. Conclusion:The CT and Ratio values of dual-source stone energy spectrum CT can effectively distinguish uric acid stones from other types of stones, and the accuracy, sensitivity, and specificity of this method for predicting uric acid stones are high.

Cachexia is a common complication in patients with lung cancer. It aggravates the toxic and side effects of chemotherapy, hinders the treatment plan, weakens the responsiveness of chemotherapy, reduces the quality of life, increases complications and mortality, and seriously endangers the physical and mental health of patients with lung cancer. The causes and pathogenesis of tumor cachexia are extremely complex, which makes its treatment difficult and complex. Controlling cachexia in lung cancer patients requires many means such as anti-tumor therapy, inhibition of inflammatory response, nutritional support, physical exercise, and relief of symptoms to exert the synergistic effect of multimodal therapy against multiple mechanisms of tumor cachexia. To date, there has been a consensus within the discipline that no single therapy can control the development of cachexia. Some therapies have made some progress, but they need to be implemented in combination with multimodal therapy after fully assessing the individual characteristics of lung cancer patients. This article reviews the application of drug therapy and nutritional support in lung cancer patients, and looks forward to the research direction of cachexia control in lung cancer patients.

It is unknown whether the famous sex-related difference in emotion processing is accounted for by biological sex, gender role, or their interaction. To clarify the issue, in Study 1 we recorded event-related potentials in response to negative and positive images of diverse intensities when 47 masculine (26 males) and 47 feminine (22 males) subjects performed a non-emotional task. The occipital P1 and N1 amplitudes were larger in women than in men, while feminine subjects showed larger N1 amplitudes than masculine subjects, regardless of sex. Moreover, feminine subjects showed enhanced frontocentral N2 (210–270 ms) amplitudes for highly and mildly negative than for neutral stimuli, while masculine subjects showed an emotion effect only for highly negative stimuli. The feminine-specific effect for mildly negative stimuli was positively correlated to the feminine score, and this correlation was located to the anterior cingulate and the superior and medial frontal gyri. Furthermore, feminine but not masculine subjects showed enhanced parietal P3 (330–560 ms) amplitudes for highly and mildly positive than for neutral stimuli, an effect positively related to the feminine score and localized to the precuneus, posterior cingulate, and superior temporal gyrus. Machine learning analyses verified that single-trial N2 and P3 amplitudes of feminine subjects reliably discriminated the intensity of negative and positive stimuli, respectively. For ecological considerations, in Study 2 we used an observational approach (n = 300) and confirmed that feminine gender role, rather than biological sex, predicted individual differences in daily experience of emotion-related psychopathological symptoms. These findings provide solid evidence for the critical impact of gender role rather than sex on emotional susceptibility.
