In recent years, the recurrence rate of stroke has gradually increased, and recurrent stroke is usually more disabling and lethal than first-ever stroke. More than half of stroke patients in China have sleep disorders, which may increase the risk of stroke recurrence and death, but are often overlooked in reality. This article mainly discusses the relationship between stroke-related sleep disorders, stroke recurrence, and mortality risk, possible mechanisms, treatment methods, and therapeutic effects.

Post-stroke cognitive impairment (PSCI) is a clinical syndrome characterized by cognitive impairment and even dementia that occurs within 3-6 months after the onset of stroke. The gut microbiota and its metabolites have been confirmed to be associated with PSCI. This article reviews associations of gut microbiota and its metabolites with PSCI, providing new ideas for early intervention and treatment of PSCI.

Post-stroke cognitive impairment (PSCI) refers to a clinical syndrome that occurs after a stroke and meets the diagnostic criteria for cognitive impairment, lasting for more than 6 months, and seriously affecting the daily life of patients. The complement system has been confirmed to be associated with PSCI. This article reviews the correlation between complement system and PSCI, as well as the possibility of complement system as an intervention target for PSCI.

Poria cocos is a classic Chinese medicine with homology of food and medicine,which is beneficial to water infiltration,spleen and stomach,calming the heart and calming the mind,etc.It is known as"nine Poria cocos in ten prescriptions".Poria cocos contains polysaccharide,triterpenoids and steroids,among them polysaccharide and triterpenoid are considered as the main active components.Modern studies have shown that Poria cocos polysaccharide triterpenes display pharmacological activities such as anti-tumor,immunomodulatory and anti-oxidation.The dissolution rate of poria cocos and triterpenes was low in the traditional decocting process,and the oral absorption rate of poria cocos was low,but the activity of poria cocos and triterpenes was still very good,indicating the high activity of poria cocos and triterpenes.Therefore,this paper systematically reviews the extraction and separation,structural identification,content determination,structural modification,biosynthesis,pharmacological activity and potential product development value of Poria cocos polysaccharide and triterpenoids,in order to provide literature reference for the development of Poria cocos grand health industry.

Objective:To investigate the correlation between heart rate variability (HRV) and early neurological deterioration (END) and poor outcomes in patients with branch atheromatous disease (BAD).Methods:Patients with BAD admitted to the Department of Neurology, Weihai Municipal Hospital from September 2020 to September 2022 were enrolled prospectively. END was defined as an increase of ≥2 points in the total score of the National Institutes of Health Stroke scale (NIHSS) or an increase of ≥1 in motor item score within 72 h of admission compared with the baseline. Poor outcome was defined as the score of the modified Rankin Scale >2 at 6 months after the onset. Multivariate logistic regression analysis was used to determine whether HRV parameters were the independent influencing factors of END and poor outcomes in patients with BAD. Results:A total of 117 patients with BAD were enrolled, including 76 males (65.0%), aged 64.27±6.95 years. Thirty-eight patients (32.4%) had END, and 21 (17.9%) had poor outcomes. Percentage of the number of pairs of adjacent R-R intervals differentiating by more than 50 ms (pNN50), number of adjacent R-R intervals differentiating by more than 50 ms (NN50), power in low frequency range (LF) and power in high frequency range (HF) in the END group were significantly lower than those in the non-END group, and the LF/HF ratio was significantly higher than the non-END group (all P<0.05). The standard deviation of the R-R interval (SDNN), standard deviation of the average of R-R intervals in all 5-min segments (SDANN), and HF in the poor outcome group were significantly lower than those in the good outcome group. Multivariate logistic regression analysis showed that HF (odds ratio [ OR] 0.994, 95% confidence interval [ CI] 0.991-0.998; P<0.001) was an independent protective factor of END in patients with BAD, and LF/HF ratio ( OR 1.455, 95% CI 1.056-2.005; P=0.022) was an independent risk factor for END in patients with BAD; SDANN ( OR 0.997, 95% CI 0.993-0.999; P=0.023) was an independent protective factor of good outcomes in patients with BAD. Conclusion:HF and LF/HF ratios are the independent influencing factors of END in patients with BAD, and SDANN is an independent influencing factor of the poor outcomes in patients with BAD, suggesting that autonomic dysfunction is involved in the pathophysiological mechanism of END and poor outcomes in patients with BAD.

Thrombotic thrombocytopenic purpura (TTP) is a rare hematological disease with typical clinical manifestations of thrombocytopenic purpura, microangiopathic hemolytic anemia, neurological symptoms, fever and kidney damage. Two patients with TTP-associated cerebral infarction complicated with microhemorrhage and their shared specific imaging findings manifestations were reported. The magnetic resonance imaging of the 2 patients showed multiple cerebral infarctions at different stages. Susceptibility-weighted imaging showed cerebral microbleeds in the infarcted area. This special imaging feature can provide important clues for early identification and diagnosis of TTP nervous system injury.

Objective:To discuss the clinical curative effect of the minimally invasive percutaneous suture technique of eight times for repairing closed injury extensor tendon zone I of finger.Methods:From February 2017 to January 2020, 12 patients (male 8, female 4) with mallet finger deformity were retrospectively studied, with an average age of 35 years (range, 18-50 years). And all the affected fingers were acute closed rupture of extensor tendon in zone I of single finger, 5 cases of the left finger and 7 cases of the right finger. There were 1 case of the thumb finger, 2 cases of the index finger, 3 cases of the middle finger, 4 cases of the ring finger and 2 cases of the little finger. 12 patients with fresh sputum mallet fingers were with 3-0 thread monofilament suture on extensor tendon zone I of finger in the minimally invasive percutaneous suture technique of eight times, and the distal end of the tendon was fixed to the base of the distal phalanx through the bone hole. Removal of the Kirschner wire 6-8 weeks, the brace was used to fix the affected finger in the dorsal extension. The flexion and extension of the affected finger was gradually strengthened. The function of the affected finger was evaluated according to the Crawford standard after operation and follow-up. The active flexion and extension range of motion of each joint of the affected finger and the contralateral healthy finger were measured, and the total action movement (TAM) of the finger were recorded. Finger function was evaluated according to TAM of the American Association of Hand Surgeons.Results:All operations were successfully completed, the operation time of the patients ranged from 18 to 25 min, with an average of 20.1±0.2 min. There was only a small amount of bleeding in the surgery. All 12 cases were followed up and the follow-up periods ranged from 6 to 14 months, with an average of 10.2±1.1 months. Mallet finger deformities were all corrected postoperatively; there were no knot exposure, skin necrosis and other complications. According to the Crawford standard, 9 cases were excellent, 2 cases were good, and 1 case was fair. The excellent and good rate was 91.7% (11/12). The mean active flexion of distal interphalangeal joints on the wounded finger and healthy finger were 82.11°±2.02° and 84.09°±2.01°, the mean active extension of distal interphalangeal joints on the wounded finger and healthy finger were -2.04°±3.01° and 0.02°±1.02°, there were significant differences between them ( t=2.447, 3.246; P=0.019, 0.004). The degrees of active joint activity of wounded finger were: 91.02°±4.01° of the metacar-pophalangeal joint, 94.04°±2.11° of the proximal interphalangeal joint, 83.01°±2.02° of the distal interphalangeal joint, and 265.05°±13.04° of total active activity; the degrees of active joint activity of healthy finger were: 93.01°±3.21° of the metacar-pophalangeal joint, 94.03°±3.07° of the proximal interphalangeal joint, 85.02°±2.01° of the distal interphalangeal joint, and 269.02°±12.10° of total active activity. The TAMs of the healthy side were 269.02°±12.10°, and the TAMs of the affected side were 265.05°±13.04°, there was no significant difference between them ( P>0.05). According to TAM system assessment criteria: excellent in 9 patients, good in 3 patients, and the excellent and good rate was 100% (12/12). Conclusion:The minimally invasive percutaneous suture technique of eight times can well repair closed injury extensor tendon zone I of finger, can have satisfactory treatment outcome in mallet finger with a simple procedure and good outcome. It is a simple, safe, effective method with minimal invasion.

Objective To understand the detection rate of hashimoto's thyroiditis (HT) and the occurrence of abnormal thyroid function in medical examination population in Huanghua City,Hebei Province.Methods Using the retrospective analysis method,the thyroid examination data of residents of Huanghua City who were examined in the Cangzhou Hospital of Traditional Chinese and Western Medicine in Hebei Province from 2014 to 2016 were collected,the detection rate of HT and the occurrence of abnormal thyroid function were analyzed.Results A total of 4 413 people were examined,aged (45.76 ± 10.13) years old;including 2 099 males and 2 314 females.The HT detection rate of the medical examination population in Huanghua City was 6.55％ (289/4 413),and there was a trend of increasing year by year (x2trend =7.126,P ＜ 0.05).The difference in HT detection rates between different genders (male:2.86％,famale:9.90％) was statistically significant (x2 =89.077,P ＜ 0.05);there was a statistically significant difference in the HT detection rates among women of different age groups (x2 =18.541,P ＜ 0.05),and there was no significant difference in the detection rates of HT among men of different age groups (x2 =8.424,P ＞ 0.05).The incidence of abnormal thyroid function in HT patients was 25.61％ (74/289),of which the highest detection rate was 34.74％ (33/95) in the 40-＜ 50 years old group;the detection rates of HT with hyperthyroidism,hypothyroidism and subclinical hypothyroidism were 3.11％ (9/289),6.57％ (19/289) and 15.92％ (46/289),respectively.The detection rate of HT with subclinical hypothyroidism was higher.Conclusions The HT detection rate of the population in Huanghua City has increased year by year,and some HT patients are associated with abnormal thyroid function,and their detection rate of HT with subclinical hypothyroidism is the highest.Early diagnosis of HT should be strengthened,and appropriate prevention and treatment measures should be taken in time to reduce the occurrence of HT with abnormal thyroid function.

Objective To compare the effect of two procedures,named "mucosa to mucosal "and "end-inside" anastomosis for cholangiojejunostomy,and analyze its applicable scope.Methods A retrospective analysis was performed on the clinical data of 340 patients who underwent choledochojejunostomy from May 2012 to May 2017 in the Navy General Hospital.These patients were divided into two groups according to the procedure they received,including " mucosa to mucosal" anastomosis (n =249) and " end-inside"anastomosis (n =91).Two anastomotic methods of intraoperative state and postoperative complications were compared respectively under normal bile duct condition and cholangiectasis condition.Results When the common bile duct was not dilated,time spent for anastomoting in "end-inside" anastomosis was significantly shorten than that in "mucosa to mucosal" anastomosis (12.7 ± 1.2) min vs.(25.2 ± 5.8) min,and incidences of anastomotic leakage,bile duct infection,liver abscess,blie duct stricture postoperation (1.6％ vs.9.7％) in "end-inside" anastomosis were significantly lower than those in "mucosa to mucosal" anastomosis (P ＜ 0.05).Whether the common bile duct was dilated or not,the shrinking extents of stoma in " end-inside" anastomosis were lower than those in " mucosa to mucosal" anastomosis (1.4 ± 0.4) mm vs.(3.6 ± 1.2),(2.9 ± 0.6) mm vs.(4.2 ± 1.2) mm with statistical significances (P ＜ 0.05).There was no significant differences between two procedures when common bile duct was dilated.Conclusion Compared to the mucosa to mucosal anastomosis,the end-inside anastomosis had the advantage of easy operating and low postoperative complications when the bile duct was not dilated.

BACKGROUND: Postoperative cholangitis is a common but severe complication after Kasai portoenterostomy for biliary atresia (BA). This study aimed to identify its prognostic factors. METHODS: Two sets of liver paraffin-embedded tissue samples were collected from BA patients who received Kasai portoenterostomy (n = 25 and n = 31, respectively). Patients were divided into non-cholangitis and cholangitis groups. The infiltration of CD4+, CD8+, CD45RO+, CD68+ cells and expression of Beclin1 were quantitatively evaluated in immunohistochemical analysis. RESULTS: Cholangitis group had a significantly lower CD8+ T cell infiltration but a higher CD45RO+ cell infiltration, and a lower Beclin1 level than non-cholangitis group (all P < 0.01). Multivariate logistic regression analysis indicated that infiltration of CD8+ cells (odds ratio [OR], 0.112; 95% confidence interval [CI], 0.022–0.577) and CD45RO+ cells (OR, 3.88; 95% CI, 1.37–11.03), and Beclin1 level (OR, 0.088; 95% CI, 0.018–0.452) were independent influence factors for early postoperative cholangitis. Receiver operating characteristic (ROC) analysis showed that area under ROC curve (AUROC) values for CD8+ cells, CD45RO+ cells and Beclin1 were 0.857, 0.738 and 0.900, respectively. CONCLUSION: Our findings demonstrated the CD8+ cells, CD45RO+ cells and Beclin1 level possessed the prognostic value for early postoperative cholangitis following Kasai operation, which may be helpful to develop new prevention and treatment strategies for postoperative cholangitis.
