In most types of erectile dysfunction, particularly in advanced stages, typical pathological features observed are reduced parenchymal cells coupled with increased tissue fibrosis. However, the current treatment methods have shown limited success in reversing these pathologic changes. Recent research has revealed that changes in autophagy levels, along with alterations in apoptosis and fibrosis-related proteins, are linked to the progression of erectile dysfunction, suggesting a significant association. Autophagy, known to significantly affect cell fate and tissue fibrosis, is currently being explored as a potential treatment modality for erectile dysfunction. However, these present studies are still in their nascent stage, and there are limited experimental data available. This review analyzes erectile dysfunction from a pathological perspective. It provides an in-depth overview of how autophagy is involved in the apoptotic processes of smooth muscle and endothelial cells and its role in the fibrotic processes occurring in the cavernosum. This study aimed to develop a theoretical framework for the potential effectiveness of autophagy in preventing and treating erectile dysfunction, thus encouraging further investigation among researchers in this area.

Senior care workers specializing in traditional Chinese medicine (TCM) healthcare have become an indispensable force in institutional care, community care, and home care. The first Chinese nursing service team aimed to improve the health of the elderly by providing continuous services for physical and mental well-being, disease prevention, physical amelioration, and overall health enhancement using TCM concepts, methods, and technologies. The primary purpose of formulating this TCM health and elderly care worker service specification was to standardize services within the TCM elderly care industry, ensuring that the elderly receive better health and elderly care services supported by technical expertise. This specification outlined the basic requirements for TCM health and elderly care workers, including standards for service content, service quality control, service evaluation, and improvement. It primarily focused on the content and requirements of TCM health and elderly care services, such as constitution identification, life care, acupoint healthcare, and TCM auxiliary nursing for elderly individuals with chronic diseases. This specification is applicable to TCM health and elderly care personnel at various levels of hospitals and healthcare institutions and is noted for its strong applicability and effectiveness.

Aim To explore the mechanism of process¬ing and increasing efficiency of Arisaematis rhizomz preparatum. Methods UPLC-Q-TOF-MS/MS tech¬nology was used to detect the chemical components be¬fore and after processing of Arisaematis rhizomz prepara¬tum, and its mechanism of action was analysed in the treatment of 44 asthma and phlegm " by using network pharmacology. A rat model of allergic asthma was es- tablished to compare the efficacy of Arisaematis rliizoma before and after processing. Results A total of 27 chemical components were identified, among which cur- cumin ,6-gingerol and other components increased after processing. Combined with the database prediction, the action mechanism of the 36 chemical components in the treatment of 44 asthma and phlegm" diseases was dis¬cussed and predicted through network pharmacology. The results of animal experiments showed that the effect of processed Arisaematis rhizoma on allergic asth¬ma was better than that of Arisaematis rhizoma, but there was no significant difference. Conclusions The addition of curcumin, 6-gingerol, camphor, demethyl- curcumin and other components after the processed Ari¬saematis rhizomz preparatum may be the reason for the synergistic effect of Arisaematis rhizomz preparatum in the treatment of allergic asthma.

OBJECTIVE: To compare the clinical efficacy and safety among three different entry points of needle knife, including tenderness point, intervertebral foramen point and articular process node, for lumbar disc herniation (LDH). METHODS: A total of 105 patients with LDH were randomly divided into a tenderness point group (35 cases, 1 case dropped off ), an intervertebral foramen point group (35 cases) and an articular process node group (35 cases, 1 case dropped off ). In the three groups, the needle knife was given at positive tenderness points of lumbosacral and hip, the external point of intervertebral foramen and the node of vertebral joint process respectively, once a week for a total of 4 times. The scores of Japanese Orthopaedic Association (JOA), Oswestry disability index (ODI), visual analogue scale (VAS) were recorded before treatment, 2 weeks and 4 weeks into treatment, and 3 months follow-up after treatment, and the clinical efficacy and safety was observed. RESULTS: Compared before treatment, the JOA scores in each group were increased 2, 4 weeks into treatment and in the follow-up (P<0.05); 4 weeks into treatment and in the follow-up, the JOA scores in the tenderness point group and the articular process node group were higher than those in the intervertebral foramen point group (P<0.05). Compared before treatment, except for ODI score 2 weeks into treatment in the intervertebral foramen point group, the ODI and VAS scores in each group were decreased 2, 4 weeks into treatment and in the follow-up (P<0.05), and the ODI scores in the tenderness point group and the articular process node group were lower than those in the intervertebral foramen point group (P<0.05). In 2 weeks into treatment, the VAS scores in the tenderness point group and the articular process node group were lower than those in the intervertebral foramen point group (P<0.05); in 4 weeks into treatment and follow-up, the VAS scores in the tenderness point group were lower than the other two groups (P<0.05). After treatment, the clinical efficacy of each group was similar (P>0.05); during the follow-up, the total effective rate in the tenderness point group was higher than that in the intervertebral foramen point group (P<0.05). There were no serious adverse events in each group. CONCLUSION The three different entry points of needle knife all could improve the symptoms of patients with LDH. The comprehensive effect of improving the subjective symptoms, lumbar function, pain degree and long-term curative effect is better in the tenderness point group.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

Objective:To provide information for further development of chronic disease management, by studying the allocation of resources required to provide services in a county in Shanxi province as required by to the pathway of China-Gates Rural Primary Health Care Service project.Methods:A questionnaire survey was made to evaluate the deployment of manpower, equipment, and drugs required by levels of county, township and village medical institutions in the health management services of hypertension and diabetes in the rural areas of Yangqu county, Shanxi province from July to August 2019.Results:A total of one county hospital, 10 township health centers and 101 village clinics participated in the investigation. In terms of service personnel participating in the project, 9 township-level medical institutions were manned with personnel who could provide diagnosis, intervention planning, and follow-up visits, and only one of them had annual evaluators; village-level medical institutions basically didn′t have diagnosis, intervention planning, and annual evaluation staff. In terms of technical equipments, there was a general lack of diabetes assessment equipment at county, township and village level medical institutions. The mandatory equipments for diabetes assessment was equipped for only 80.0%, 79.0%, and 37.8% of the three levels of institutions, respectively. Village clinics lack hypertension assessment equipment and had no diabetes diagnosis equipment at all.Conclusions:The chronic disease management personnel, equipment, and drug supply in the rural areas of a county in Shanxi province are unbalanced among counties, townships, and villages. The quality of chronic disease management services should be improved through effective and rational use of resources.

Multiple measurements of nocturnal penile tumescence and rigidity (NPTR) are widely accepted as a method to differentiate psychogenic erectile dysfunction (ED) from organic ED. However, direct evidence remains limited regarding the first-night effect on NPTR measurement using the RigiScan. Here, we evaluated the first-night effect on the results of NPTR measurement to validate the necessity of NPTR measurement for two consecutive nights, particularly when abnormal first-night measurements are recorded in a laboratory setting. We retrospectively reviewed 105 patients with a complaint of ED, who underwent NPTR measurement using the RigiScan in the Department of Infertility and Sexual Medicine, the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China), for two consecutive nights, during the period from November 2015 to May 2016. NPTR parameters were collected and analyzed. We found that more effective nocturnal erections were detected during the second night than during the first night (P <0.001). Twenty percent of all patients had no effective erection during the first night, but exhibited at least one effective erection during the second night. The negative predictive value of NPTR measurement during the first night was 43.2%; this was significantly lower than that on the second night (84.2%; P = 0.003). Most NPTR parameters were better on the second night than on the first night. The first-night effect might be greater among patients younger than 40 years of age. In conclusion, two consecutive nightly measurements of NPTR can avoid a false-abnormal result caused by the first-night effect; moreover, these measurements more accurately reflect erectile capacity, especially when the first-night record is abnormal in a laboratory setting.

A method was established for simultaneous determination of 21 active constituents including flavanols, isoflavones, flavonols, dihydroflavones, dihydroflavonols, chalcones, pterocarpan, anthocyanidins and phenolic acids in Spatholobi Caulis by ultra fast liquid chromatography with triple quadrupole linear ion trap mass spectrometry(UFLC-QTRAP-MS/MS). Then, it was employed to analyze and evaluate the dynamic accumulation of multiple bioactive constituents in Spatholobi Caulis. The chromatographic separation was performed on a XBridge®C_(18)(4.6 mm×100 mm, 3.5 μm) at 30 ℃ with a gradient elution of 0.3% formic acid aqueous solution-methanol, and the flow rate was 0.8 mL·min~(-1), using multiple-reaction monitoring(MRM) mode. A comprehensive evaluation of the multiple bioactive constituents was carried out by gray correlation analysis(GRA). The 21 target components showed good linearity(r>0.999 0) in the range of the tested concentrations. The average recovery rates of the 21 components were from 97.46% to 103.6% with relative standard deviations less than 5.0%. There were differences in the contents of 21 components in Spatholobi Caulis at diffe-rent harvest periods. Spatholobi Caulis had high quality from early November to early December, which is consistent with the local tradi-tional harvest period. This study reveals the rule of the dynamic accumulation of 21 components in Spatholobi Caulis and provides basic information for the suitable harvest time. At the same time, it provides a new method reference for the comprehensive evaluation of the internal quality of Spatholobi Caulis.
