ObjectiveTo explore the effect of different drying conditions on the appearance and intrinsic quality indicators of Pinelliae Rhizoma for screening suitable drying conditions， so as to provide reference for its standardized production and quality evaluation. MethodsDifferent dried samples of Pinelliae Rhizoma were prepared by lime-assisted sweating method and intermittent drying method. Visual analysis was employed to measure the color brightness values（L^*） of the surface， cross-section and powder of the samples， texture analyzer was used to determine the hardness of the samples under different drying conditions. The total starch content was calculated by measuring the contents of amylose and amylopectin in the samples with ultraviolet-visible spectroscopy. High performance liquid chromatography（HPLC） was used to determine the contents of seven nucleoside components（uracil， hypoxanthine， uridine， inosine， guanosine， β-thymidine and adenosine） in the samples. Pearson correlation analysis was conducted to explore the correlation between the external characteristics and intrinsic indicators of the different dried samples. Principal component analysis（PCA） was used to comprehensively rank the data of various indicators， and partial least squares-discriminant analysis（PLS-DA） was used to screen differential components with variable importance in the projection（VIP） value>1. Furthermore， the difference between the optimal drying condition for Pinelliae Rhizoma and the traditional sun-drying method was explored by independent samples t-test. ResultsWith the increase of temperature， the color of the intermittently dried samples gradually deepened， while their hardness gradually decreased. Concurrently， the contents of extract， total starch， uridine and adenosine exhibited an upward trend， whereas the contents of uracil， hypoxanthine and inosine displayed a downward trajectory. Compared with the intermittent drying group， the content of extract in the samples subjected to lime-assisted sweating increased. With the increase of lime dose， the hardness and the total content of nucleoside components in the samples showed a downward trend， while the total starch content showed an upward trend. Correlation analysis showed that the comprehensive score of L^* was negatively correlated with the contents of uracil， hypoxanthine and inosine， and positively correlated with the contents of uridine， guanosine and adenosine. Hardness was negatively correlated with adenosine content， and positively correlated with the contents of inosine， uracil and hypoxanthine. Through comprehensive consideration and comprehensive score of principal components， the method of 5% lime-mixed sweating for 6 days emerged as the top-ranking approach. Except for the extract， the results of independent samples t-test showed that there was no significant difference between the 5% lime-mixed sweating for 6 days and the traditional sun-drying in terms of other content indicators. ConclusionThe whiteness and firmness of Pinelliae Rhizoma exhibit significant correlations with its chemical composition， while uridine， uracil， guanosine， adenosine and inosine are the key constituents responsible for the quality difference of Pinelliae Rhizoma under different drying conditions. The lime-assisted sweating method optimized in this study can be proposed as a viable alternative to the traditional sun-drying method. This method not only ensures the quality of the medicinal material but also effectively reduces the drying time and prevents mold contamination， which provides a valuable reference for the standardization of drying conditions and the establishment of quality evaluation criteria for Pinelliae Rhizoma.

Ductal carcinoma in situ of the breast (DCIS) most commonly manifests as asymptomatic calcifications at mammography. The most common manifestation of MRI is nonmass enhancement. The ultrasound mainly presents as a hypoechoic irregular hypervascular mass without posterior features. Core-needle biopsy is a commonly used method for preoperative diagnosis of DCIS. Due to differences in needle type and sample size, there is a certain degree of pathological upgrading of the lesion. In recent years, there has been controversy over the diagnosis and treatment of DCIS. With the development of breast disease diagnostic technology, advances in digital breast tomography, artificial intelligence, and radiomics are expected to help DCIS management and address issues such as overdiagnosis.

The application of function-preserving pancreatic surgery as a restrictive resection technique is primarily targeted towards benign or those with borderline or low-grade lesions. This approach has been shown to significantly improve both short-term and long-term quality of life outcomes for patients following surgical intervention. In comparison to conventional laparoscopic procedures, robotic surgical systems have demonstrated superior efficacy and precision when employed in pancreas surgeries, and the safety and reliability are widely recognized within the medical community. Nevertheless, there remains a dearth of research investigating the specific appli-cations of robotic-assisted function-preserving pancreatic surgery. Consequently, the authors compre-hensive review the latest progress on robot-assisted function-preserving pancreatic surgery, while highlighting of surgical scope, techniques utilized during these procedures as well as associated prognostic considerations.

Objective:To evaluate the clinical effectiveness and safety of combined face and neck injections of botulinum toxin type A to improve face and neck aging.Methods:From January 2020 to January 2023, 30 female patients with age of 29-66 years, average (42.2±8.8) years, underwent face and neck combined injection of A-type botulinum toxin in the Department of Dermatology, Henan Provincial People′s Hospital. The injection sites included the forehead, between the eyebrows, around the eyes, the dorsum of the nose, and the mandibular margin, etc. The efficacy was assessed by the wrinkle severity scale (FWS) and the AB value of the distance from the lowest point of the mandibular margin on the midline of the hemiface to the level of the medial canthus at 4 and 24 weeks after the injection, as well as the subjective degree of improvement by the Global Aesthetic Improvement of the Face Scale (GAIS) and the Self-perception of Age (SPA), and the satisfaction of the patients and post-injection adverse reactions.Results:At 4 weeks after the injection, the total effective rate of improvement of wrinkles in all parts of the upper face was 100% (30/30), and there was a statistically significant difference in the improvement of AB ( t=28.35, P<0.05). At 24 weeks after the injection, the total effective rate of improvement of wrinkles in all parts of the upper face ranged from 16.7% (5/30) to 36.7% (11/30), and the improvement of AB still showed a statistically significant difference ( t=3.98, P<0.05). 100% (30/30) and 66.7% (20/30) of patients assessed their facial status as improved on GAIS at 4 and 24 weeks after the injection, respectively, and 100% (30/30) and 63.3% (19/30) of patients perceived themselves as younger. Patient satisfaction was 100% (30/30). After injection, there were 5 cases of slight ecchymosis at the injection site and 1 case of weakness in eyebrow elevation in the 30 patients, which disappeared on their own within 1 to 2 weeks. Conclusions:The therapeutic effect of face and neck combined injection of botulinum toxin type A on facial rejuvenation is obvious, with high patient′s satisfaction and no serious adverse reactions.

BACKGROUND:In recent years,increasing studies have shown that low-intensity pulsed ultrasound can promote the healing of acute tendon injuries,but the specific mechanism is still unclear. OBJECTIVE:To observe the effect of low-intensity pulsed ultrasound on early angiogenesis after acute tendon injury,and to detect the regulatory relationship of low-intensity pulsed ultrasound with vascular endothelial growth factor-related signaling pathways,so as to reveal its potential mechanism of action. METHODS:Animal models of acute Achilles tendon injury were established using local injection of type I collagenase for 3 days in SPF male Sprague-Dawley rats aged 8-12 weeks,and were then randomly divided into ultrasound group and control group.In the ultrasound group,low-intensity pulsed ultrasound was treated daily with a small ultrasonic probe with an effective radiation area of 1 cm2 perpendicular to the Achilles tendon.No intervention was performed in the control group.Ultrasound imaging examination was performed 2 weeks later to observe the early healing of the tendon.Hematoxylin-eosin staining and CD31 immunohistochemical staining were performed to observe the changes in the number of blood vessels in the tissues after 1 and 2 weeks of treatment.The expression of vascular endothelial growth factor-related signaling pathway molecules in Achilles tendon tissues was detected by western blot or qRT-PCR. RESULTS AND CONCLUSION:Compared with the control group,the Achilles tendon in the ultrasound group was more continuous,the echo intensity was lower and more uniform,and the tendon thickness was significantly reduced(P<0.05).Hematoxylin-eosin staining and CD31 immunohistochemical staining results showed that after 2 weeks of treatment,the number of new vessels in the ultrasound group was significantly increased compared with the control group(P<0.05).Western blot and qRT-PCR results showed that after 2 weeks of continuous ultrasound intervention,the protein or mRNA expressions of vascular endothelial growth factor,Yes-associated protein,angiopoietin-2 and cysteine-rich angiogenic inducer 61 in the Achilles tendon of the ultrasound group were significantly higher than those of the control group(P<0.05).These finding indicate that low-intensity pulsed ultrasound significantly increases the number of blood vessels in the early stage of acute tendon injury and accelerate tendon healing by up-regulating vascular endothelial growth factor expression.

Abstract On 18 May 2021, the Center for Disease Control and Prevention (CDC) of X District in P City, Z Province received a co-investigation of a suspected case of intentional HIV transmission from the public security branch, and conducted epidemiological investigations on Zhao and Wang (both males). Wang was confirmed HIV-positive in 2019. Zhao had unprotected sexual encounters several times with Wang in March 2021 without being informed of Wang's HIV infection. Zhao developed fever, sore throat and other symptoms of acute infection phase on 28 March, and were confirmed HIV positive by the CDC of P City on 11 May. Zhao did not have sex with anyone else before or after having sex with Wang. In addition, Zhao had no history of surgery, blood transfusions, drug use or any other history of HIV exposure. Laboratory tests conducted by the CDC of Z Province showed that the HIV nucleic acid sequences between the samples of Zhao and Wang had a high degree of homology. Combined with the epidemiological investigation, laboratory testing and the evidence from the public security branch, it was concluded that Wang intentionally transmitted HIV to Zhao through unprotected anal sex without disclosing his HIV infection status.
