Based on the development of conditions, the etiology and pathogenesis of jingjin (muscle region of meridian) diseases are summarized as 3 stages, i.e. stagnation due to over-exertion at early stage, manifested by tendon-muscle contracture and tenderness; cold condition due to stagnation, interaction of stasis and cold, resulting in clustered nodules at the middle stage; prolonged illness and missed/delayed treatment, leading to tendon-muscle contracture and impairment of joint function at the late stage. It is proposed that the treatment of jingjin diseases should be combined with the characteristic advantages of fire needling and bloodletting technique, on the base of "eliminating stagnation and bloodletting/fire needling". This combined therapy warming yang to resolve stasis and dispels cold to remove nodules, in which, eliminating the stagnation is conductive to the tissue regeneration, and the staging treatment is delivered in terms of the condition development at different phases.

The end of the COVID-19 infection peak in 2022 prompts a backlog of cardiovascular surgical patients to gradually return to the hospital, resulting in a surge in cardiovascular surgeries. However, against the backdrop of the COVID-19 pandemic, the clinical practice of cardiovascular surgery faces many problems. Therefore, organized by Beijing Anzhen Hospital, experts in cardiovascular surgery and related fields have formulated hospital expert experience on perioperative treatment principles of cardiovascular surgery for patients infected with COVID-19. This article summarizes the clinical decision-making of patients requiring cardiovascular surgery after COVID-19 infection, and advises on the corresponding recommendations according to the existing evidence-based medical evidence as well as the actual clinical practice experience of relevant experts. The main content of the article includes special requirements for cardiovascular surgical treatment indications in patients with COVID-19 infection, selection of surgical timing, special requirements of preoperative, intraoperative and postoperative management, etc., which aims to provide COVID-19-infected patients with guidance on rational decision-making when receiving cardiovascular surgery.

Objective: To investigate the clinical presentation and genetic characteristics of malignant infantile osteopetrosis. Methods: This was a retrospective case study. Thirty-seven children with malignant infantile osteopetrosis admitted into Beijing Children's Hospital from January 2013 to September 2022 were enrolled in this study. According to the gene mutations, the patients were divided into the CLCN7 group and the TCIRG1 group. Clinical characteristics, laboratory tests, and prognosis were compared between two groups. Wilcoxon test or Fisher exact test were used in inter-group comparison. The survival rate was estimated with the Kaplan-Meier method and the Log-Rank test was used to compare the difference in survival between groups. Results: Among the 37 cases, there were 22 males and 15 females. The age of diagnosis was 0.5 (0.2, 1.0) year. There were 13 patients (35%) and 24 patients (65%) with mutations in CLCN7 and TCIRGI gene respectively. Patients in the CLCN7 group had an older age of diagnosis than those in the TCIRGI group (1.2 (0.4, 3.6) vs. 0.4 (0.2, 0.6) years, Z=-2.60, P=0.008). The levels of serum phosphorus (1.7 (1.3, 1.8) vs. 1.1 (0.8, 1.6) mmol/L, Z=-2.59, P=0.010), creatine kinase isoenzyme (CK-MB) (457 (143, 610) vs. 56 (37, 82) U/L, Z=-3.38, P=0.001) and the level of neutrophils (14.0 (9.9, 18.1) vs. 9.2 (6.7, 11.1) ×10⁹/L, Z=-2.07, P=0.039) at diagnosis were higher in the CLCN7 group than that in the TCIRG1 group. However, the level of D-dimer in the CLCN7 group was lower than that in the TCIRGI group (2.7 (1.0, 3.1) vs. 6.3 (2.5, 9.7) μg/L, Z=2.83, P=0.005). After hematopoietic stem cell transplantation, there was no significant difference in 5-year overall survival rate between the two groups (92.3%±7.4% vs. 83.3%±7.6%, χ²=0.56, P=0.456). Conclusions: TCIRGI gene mutations are more common in children with osteopetrosis. Children with TCIRGI gene mutations have younger age, lower levels of phosphorus, CK-MB, and neutrophils and higher level of D-dimer at the onset. After hematopoietic stem cell transplantation, patients with CLCN7 or TCIRGI gene mutations have similar prognosis.

OBJECTIVE: This study aimed to determine the spatiotemporal distribution and epidemiological characteristics of hospital admissions for carbon monoxide poisoning (COP) in Guangdong, China, from 2013 to 2020. METHODS: Data on age- and sex- specific numbers of hospital admissions due to COP in Guangdong (2013-2020) were collected. Daily temperatures were downloaded through the China Meteorological Data Sharing Service System. We analyzed temporal trends through time series decomposition and used spatial autocorrelation analysis to detect spatial clustering. The distributed lag nonlinear model was used to quantify the effects of temperature. RESULTS: There were 48,854 COP admissions over the study period. The sex ratio (male to female) was 1:1.74. The concentration ratios (M) ranged from 0.73-0.82. The highest risk occurred in January (season index = 3.59). Most cases were concentrated in the northern mountainous areas of Guangdong with high-high clustering. COP in the study region showed significant spatial autocorrelation, and the global Moran's Ivalue of average annual hospital admission rates for COP was 0.447 ( P < 0.05). Low temperatures were associated with high hospital admission rates for COP, with a lag lasting 7 days. With a lag of 0 days, the effects of low temperatures [5th (12 °C)] on COP were 2.24-3.81, as compared with the reference temperature [median (24 °C)]. CONCLUSION COP in Guangdong province showed significant temporal and spatial heterogeneity. Low temperature was associated with a high risk of COP, and the influence had a lag lasting 7 days.

The anterior cruciate ligament (ACL) injury is a common sports injury that has a significant impact on knee function and patients′ mobility. With the popularity of national fitness campaign in China, the incidence of ACL injury is increasing year by year. Currently, there still lacks clinical standards or guidelines on how to choose appropriate treatment methods, surgical plans and rehabilitation protocols for ACL injury. In order to timely reflect the new treatment concept of ACL injury, standardize its diagnosis and treatment and improve the curative effect, the Sports Medicine Society of Chinese Research Hospital Association and the Editorial Board of Chinese Journal of Trauma organized domestic orthopedic and sports medicine experts to formulate the "clinical evidence-based guideline for the diagnosis and treatment of anterior cruciate ligament injury (2022 version)" based on the level of evidence-based medicine and in compliance with the principle of scientificity, practicability and advancement. The present guideline includes 12 recommendations for the diagnosis, treatment and rehabilitation of ACL injury in order to provide guidance and assistance for the clinical diagnosis and treatment of ACL injury in China.

No consensus on standardized technique of enterostomy creation has been made meanwhile high heterogeneity of surgical procedure exists in 'stoma creation' chapters of textbooks or atlases of colorectal surgery. The present article reviews the anatomy of tendinous aponeurotic fibers which is crucial for abdominal wall tension and integrity. Through empirical practice we hypothesize a procedure of enterostomy creation basied on abdominal wall tension plus anchor suture for fascia fixation which could theoretically decrease short-term stoma complication rates and long-term parastomal hernia rates. Surgical techniques are as followed: (1) preoperative stoma site mark for de-functioning ileostomy should be positioned at the lateral border of rectus abdominis muscle (RAM) to decrease the difficulty of stoma reversal and for permanent colostomy should be placed overlying the RAM to promote adhesion; (2)Optimal circular removal or lineal opening of skin, and avoid dissection of subcutaneous tissue; (3) Lineal dissection of natural strong fascia (rectus sheath) at stoma site and blunt separation of muscular fibers. The tunnel of the fascia should be made with appropriate size without undue tension. To prevent the formation of dead space, additional suturing at fascia layer is unnecessary. (4) Anchor suture for fascia fixation at two ends of fascia opening could be considered to avoid delayed fascia disruption and parastomal hernia. (5) After pull-through of ileum or colon loop, 4-8 interrupted seromuscular sutures could be placed to attach loop to skin. For ileostomy, self-eversion of mucosa can be successful in vast majority of cases and a Brooke ileostomy is not necessary. The efficacy and safety of this procedure should be tested in future trials.

The occupational burnout was mainly affected by occupational stress and fear of the epidemic.

Biopharmaceuticals are formulated using a variety of excipients to maintain their storage stability.However,some excipients are prone to degradation during repeated use and/or improper storage,and the impurities generated by their degradation are easily overlooked by end users and are usually not strictly monitored,affecting the stability of biopharmaceuticals.In this study,we evaluated the degra-dation profile of polyol excipient glycerol during repeated use and improper storage and identified an unprecedented cyclic ketal impurity using gas chromatography with mass spectrometry(GC-MS).The other polyol excipient,mannitol,was much more stable than glycerol.The effects of degraded glycerol and mannitol on the stability of the model biopharmaceutical pentapeptide,thymopentin,were also evaluated.The thymopentin content was only 66.4％in the thymopentin formulations with degraded glycerol,compared to 95.8％in other formulations after the stress test.Most glycerol impurities(i.e.,aldehydes and ketones)reacted with thymopentin,affecting the stability of thymopentin formulations.In conclusion,this work suggests that more attention should be paid to the quality changes of excipients during repeated use and storage.Additional testing of excipient stability under real or accelerated conditions by manufacturers would help avoid unexpected and painful results.

OBJECTIVE: To investigate the potential mechanisms of electroacupuncture (EA) to prevent ischemic stroke. METHODS: The method of middle cerebral artery occlusion (MCAO) was employed to establish a rat model of ischemic stroke. Seventy-eight Sprague-Dawley rats were divided into the sham group, MCAO + EA control (EC) group, and MCAO + EA (EA) group according to a random number table (n=26 per group). EA was applied to the acupoints of Baihui (DU 20) and Shenting (DU 24) 5 min and 6 h, respectively after the onset of MCAO. Rats in the sham and EC groups received only light isoflurane anesthesia for 30 min after MCAO. The neuroprotective effects of EA were evaluated by rota-rod test, neurological deficit scores and infarct volumes. Additionally, Nissl staining and immunostaining were performed to examine brain damage, rod formation, cellular apoptosis, and neuronal loss induced by ischemia. The activities of caspase-3, and expression levels of cofilin and p-cofilin in mitochondria and cytoplasm after ischemic injury were determined by Western blot. RESULTS: Compared with the EC group, EA significantly improved neuromotor function and cognitive ability after ischemic stroke (P<0.05 or P<0.01). Therapeutic use of EA also resulted in a significant decrease of cofilin rod formation and microtubule-associated protein-2 (MAP2) degradation in the cortical penumbra area compared with the EC rats (P<0.01). Furthermore, Western blot analysis showed that EA stimulation significantly inhibited mitochondrial translocation of cofilin and caspase-3 cleavage (P<0.05 or P<0.01). Additionally, brain damage (infarct volume and neuropathy), cellular apoptosis and neuronal loss induced by ischemia were remarkably suppressed by EA in the cortical penumbra of rats (P<0.05 or P<0.01). CONCLUSION EA treatment after ischemic stroke may attenuate ischemic brain injury and cellular apoptosis through the regulation of mitochondrial translocation of cofilin, a novel mechanism of EA therapy.
