OBJECTIVETo observe the therapeutic effects of shoulder-elbow elastic immobilization and functional exercise for injured shoulder arthrochalasis, and compare it with forearm-suspending immobilization and functional exercise therapy.
METHODSThe patients with injured shoulder arthrochalasis were randomly divided into treatment group (38 cases) and control group (37 cases). Treatment group underwent the therapy of shoulder-elbow elastic band immobilization and functional exercise; control group was managed by forearm-suspending band immobilization and functional exercise therapy.
RESULTSIn treatment group, 29 (76.3%) cases recovered, 7 (18.4%) improved and 2 (5.3%) failed; in control group, 15 (40.5%) cases recovered, 15 (40.5%) cases improved and 7 (19.0%) failed. The differences between two groups were statistically significant (P<0.01). The AHI (acromio-humeral interval) ranged from 8 to 19 mm (11.9+/-5.1) in treatment group and 8 to 27 mm (14.2+/-5.4) in control group, and the difference was also statistically distinct (t=2.7525, P<0.01).
CONCLUSIONThe treatment with shoulder-elbow elastic band immobilization and exercise therapy for injured shoulder arthrochalasis is a safe and effective method. Immobilization with shoulder-elbow elastic band is better than forearm-suspending band for injured shoulder arthrochalasis.

OBJECTIVE:
To investigate protective effect of Cordyceps sinensis (CS) through autophagy-associated adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signaling pathway in acute kidney injury (AKI)-induced acute lung injury (ALI).
METHODS:
Forty-eight male Sprague-Dawley rats were divided into 4 groups according to a random number table, including the normal saline (NS)-treated sham group (sham group), NS-treated ischemia reperfusion injury (IRI) group (IRI group), and low- (5 g/kg·d) and high-dose (10 g/kg·d) CS-treated IRI groups (CS1 and CS2 groups), 12 rats in each group. Nephrectomy of the right kidney was performed on the IRI rat model that was subjected to 60 min of left renal pedicle occlusion followed by 12, 24, 48, and 72 h of reperfusion. The wet-to-dry (W/D) ratio of lung, levels of serum creatinine (Scr), blood urea nitrogen (BUN), inflammatory cytokines such as interleukin- β and tumor necrosis factor- α, and biomarkers of oxidative stress such as superoxide dismutase, malonaldehyde (MDA) and myeloperoxidase (MPO), were assayed. Histological examinations were conducted to determine damage of tissues in the kidney and lung. The protein expressions of light chain 3 II/light chain 3 I (LC3-II/LC3-I), uncoordinated-51-like kinase 1 (ULK1), P62, AMPK and mTOR were measured by Western blot and immunohistochemistry, respectively.
RESULTS:
The renal IRI induced pulmonary injury following AKI, resulting in significant increases in W/D ratio of lung, and the levels of Scr, BUN, inflammatory cytokines, MDA and MPO (P<0.01); all of these were reduced in the CS groups (P<0.05 or P<0.01). Compared with the IRI groups, the expression levels of P62 and mTOR were significantly lower (P<0.05 or P<0.01), while those of LC3-II/LC3-I, ULK1, and AMPK were significantly higher in the CS2 group (P<0.05 or P<0.01).
CONCLUSION
CS had a potential in treating lung injury following renal IRI through activation of the autophagy-related AMPK/mTOR signaling pathway in AKI-induced ALI.

ObjectiveTo observe the therapeutic effect of Chaishao Longmu decoction on insomnia in the patients with the syndrome of live depression and spleen deficiency and explore the correlation between infrared thermal imaging and insomnia with liver depression and spleen deficiency. MethodA total of 72 insomnia patients treated in the outpatient department of Shenzhen Hospital of Guangzhou University of Chinese Medicine (Futian) from May to December in 2022 were selected and randomized into a treatment group and a control group, with 36 patients in each group. The patients in the treatment group were treated with Chaishao Longmu decoction and those in the control group with eszopiclone for 4 weeks. The clinical efficacy, Pittsburgh sleep quality index (PSQI) score, TCM syndrome score and infrared thermal imaging characteristics [temperature and temperature changes of frontal sleep line, frontal region, anterior trunk, Zhongwan (CV12), conception vessel (CV), left hypochondrium, right hypochondrium, dorsal trunk, and governor vessel (GV)] of two groups were determined before and after treatment. ResultAfter treatment, the clinical response rate in treatment group was 91.67% (33/36), which was higher than that (66.67%, 24/36) in the control group (Z=-2.617, P<0.01). The treatment in both groups decreased the PSQI score and TCM syndrome score (P<0.01), and the decreases were more significant in treatment group than in the control group (P<0.01). After treatment, the total response rate of sleep line improvement in the treatment group was 86.11% (31/36), which was higher than that (66.67%, 24/36) in the control group (Z=-2.591, P<0.05). The frontal temperature of the two groups decreased (P<0.01) after treatment. Compared with those before treatment, the temperatures of anterior trunk, CV12, CV, left hypochondrium, right hypochondrium, dorsal trunk, and GV rose after treatment (P<0.01). After treatment, the treatment group had lower frontal temperature and higher temperatures of anterior trunk, CV12, CV, left hypochondrium, right hypochondrium, dorsal trunk, and GV than the control group (P<0.01). The treatment in the treatment group reduced the ∆T values of GV (P<0.01) and increased that of the CV12, CV, left hypochondrium, and right hypochondrium (P<0.05,P<0.01). The treatment in the control group increased the ∆T value of CV12 (P<0.01). After treatment, the treatment group had lower ∆T values of GV (P<0.01) and higher ∆T value of CV12, CV, left hypochondrium, and right hypochondrium (P<0.05, P<0.01) than the control group. Compared with that before treatment, the temperature difference between GV and CV in the two groups increased after treatment (P<0.01). According to the infrared thermal image characteristics, the normal temperature difference between GV and CV was within the range of 0.5-1. The median value after treatment in the treatment group was 0.69 (0.52, 0.88), which was within the normal range, indicating that the treatment group outperformed the control group. ConclusionChaishao Longmu decoction can alleviate short-term insomnia by soothing liver, invigorating spleen, harmonizing the middle energizer, and regulating GV and CV. With definite clinical effect, this decoction deserves promotion. Furthermore, the frontal temperature, sleep line, CV12, CV ∆T, and temperature difference between GV and CV revealed by the infrared thermal images could be used for the diagnosis and of insomnia with liver depression and spleen deficiency.

Method The data in 2008 were exported from the computer databases of 8 large and medium-sized cities' emergency medical centers in our country.The thorough records of data were conducted to statistical analysis. Results ( 1 ) The scheduling time, running time, rescue time, returning time, total time and service radius in the pre-hospital medical care group were 2.16± 1.10(min), 14.01 ±6.82(min), 12.12±5.96(min), 14.08± 6.85(min), 42.34± 20.21(min)and 8.50±4.18(km), and the above parameter in the non-death group were 2.19 ± 1.13(min), 14.15 ± 7.14(min),11.60±6.72(min), 14.92 ±6.89(min), 41.86± 19.53(minutes) and 8.63±4.31(Km), and the above parameter in the death group were 2.10± 1.08(min), 13.68 ± 7.14(min), 25.25 ± 12.34(min), 13.75±6.48(min), 54.74 ± 25.47(min) and 7.86± 3.91(Km), and the above parameter in the non-sudden cardiac death group were2.09± 1.03(min), 13.58±6.78(min), 25.53± 12.34(min), 13.60± 6.54(min), 53.79±23.77(min) and 7.67 ± 3.86(Km), and the above parameter in the sudden cardiac death group were 2.12 ±1.02(min), 14.10±7.05(min), 24.79± 12.08(min), 13.79±6.61(min), 54. 80 ± 25. 36( min) and 7.90±3.92(Km) respectively. The scheduling time, running time, returning time and service radius in the death group were less than those of the non-death group, but the rescue time and total time of the former were more than those of the latter respectively ( P < 0.05 or P < 0. 001 ). The scheduling time and returning time didn' t have significant difference between the sudden cardiac death group and the non-sudden cardiac death group respectively ( P > 0.05), but the running time, total time and service radius of the sudden cardiac death group were more than those of the non-sudden cardiac death group, and the rescue time of the former was less than that of the latter respectively ( P < 0.05 or P < 0.001 ). (2)The patients' amount in pre-hospital medical care group, the non-death group, the death group, the non-sudden cardiac death group and the sudden cardiac death group were at most in first quarter, and the least time slice of patients' amount were 4:00~ 6:00, 4:00~6:00, 4:00~ 6:00, 22:00~ 24:00, 2:00~4:00 respectively, and the most time slice of patients' amount were 20:00~ 22:00, 20:00~22:00, 8:00~ 10:00, 2:00 ~ 4:00, 8:00 ~ 10:00 respectively. (3)In 241 876 cases of pre-hospital medical care group, the patients' amount of trauma was at most, whose age grades was by far among21 ~50, and the others in sequence were nervous system, circulatory system, other group, digestive system, respiratory system and poisoning group respectively, whose age grades in nervous system, circulatory system and respiratory system was by far above 51, especially above 70. The patients' age grades in other group and digestive system had two climax age groups, which the one was 21 ~ 30, and the other was above 70. The patients' age grades in poisoning group was by far among 21 ~ 50, which the patients' amount of acute alcoholism was at the most. (4) In 12 568 cases of death group, the death amount of circulatory system, other group, respiratory system, nervous system and digestive system ranked at the lst,2nd,4th,5th 8th respectively, whose age grades was by far above 51, especially above 70,and the patients' amount of sudden cardiac death was at the most in the death amount of circulatory system. The death amount of trauma and poisoning group ranked at the 3rd, 6th respectively, whose age grades was by far among 21 ~ 50. (5)The total amount, the death amount and the sudden cardiac death amount of male patients were more than those of female patients. (6)The percentage of the death group to the pre-hospital medical care group was 5.20%, and the percentage of the sudden cardiac death group to the pre-hospital medical care group was 1.29%,and the percentage of the sudden cardiac death group to the death group was 24.87 %, and the percentage of the sudden cardiac death group to the circulatory system group was 67.33 %. Conclusions ( 1 )The trauma and the sudden cardiac death are the overriding reason of disease and the overriding reason of death in our large and medium-sized cities respectively. (2) It is very important to cut the death rate of the middle-old age patients by strengthening prevention and cure of cardiovascular and cerebrovascular diseases, discerning the critical illness early and improving the level of pre-hospital medical care. (3)It is a strong method to decrease the total amount and the death amount of the trauma, especially in traffic accident, by strengthening safety in production, observing traffic regulation and enhancing the legal awareness.

OBJECTIVE To provide reference for rational use of cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. METHODS Retrieved from Web of Science, PubMed, SpringerLink, CNKI, Wanfang Data and VIP database, and so on, the literature about lung toxicity related to CDK4/6 inhibitors were collected and analyzed statistically with Excel 2013 software. RESULTS A total of 12 literature which met the inclusion and exclusion criteria were included; 13 patients were involved, among which 3 cases were from the United States, 3 from Japan, 2 from India, and 1 from Israel, Spain, France, Australia and Saudi Arabia respectively; all patients were female, aged between 43-89 years, of whom 8 were treated with palbocicilib, 3 with abemacilib, and 2 with ribociclib. The lung toxicity of patients after medication occurred from 1 week to 15 months; the majority of patients were hospitalized with the symptom such as difficulty breathing, chest tightness, shortness of breath, dry cough, etc. The lung toxicity mainly manifested as interstitial lung disease, eosinophilic pneumonia, mediastinal and pulmonary granulomatous reaction, drug-induced pneumonia, diffuse alveolar damage, organizing pneumonia and so on. The shortest treatment duration was 3 weeks, and the longest was 6 months. The treatment measures included drug withdrawal, intravenous use of antibiotics, intravenous use of systemic steroids, oxygen inhalation, and so on; after treatment, 8 patients improved or recovered, and 5 patients died due to deterioration. One patient developed lung toxicity again after reuse of such drugs and must stop drugs permanently. CONCLUSIONS Lung toxicity related to CDK4/6 inhibitors possibly cause mortality. It is necessary to make early judgment, stop the drug in time, and give patients systemic steroids, oxygen inhalation and other treatment measures as soon as possible.

Zhishi Shaoyaosan is the 34th prescription in the Catalogue of Ancient Classic Formulas (Second Batch) published by the National Administration of Traditional Chinese Medicine in 2023. It is widely used in clinical practice and has a definite curative effect. However, there is currently a lack of its ancient literature analysis and textual research, and there is no corresponding Chinese patent medicine preparation. By consulting and combing the relevant ancient books of traditional Chinese medicine, this paper analyzes and conducts textual research of the origin, composition, measurement, administration, and efficacy of Zhishi Shaoyaosan. The results show that Zhishi Shaoyaosan is derived from Essentials from the Golden Cabinet written by Zhang Zhongjing in the Eastern Han Dynasty. It is mainly recorded in the name of Zhishi Shaoyaosan in the literature of the past dynasties. The prescription is composed of Aurantii Fructus Immaturus and Paeoniae Radix Alba. The processing method is stir-frying Aurantii Fructus Immaturus to scorch and using raw Paeoniae Radix Alba. The dose of the prescription recorded in the ancient books is mainly an equal amount of Aurantii Fructus Immaturus and Paeoniae Radix Alba in one square-cun spoon, taken three times a day, which is converted into a modern dose of 1.5 g each time (0.75 g Aurantii Fructus Immaturus and 0.75 g Paeoniae Radix Alba each time). The components of the prescription are ground into powder and taken with barley porridge, three times a day. The efficacy is to break stagnated Qi, harmonize blood, and relieve restlessness and pain. It is mainly used to treat postpartum abdominal pain, acute pelvic inflammatory disease, acute cholecystitis and intestinal diseases, stroke sequelae, and other diseases. This study combs and analyzes the ancient literature recording Zhishi Shaoyaosan and clarifies the key information of the prescription, which provides a basis for promoting the research and development of its patent medicine.
