Objective:To observe the pathological changes of levator palpebrae superiors muscle in patients with different severities of simple congenital ptosis (SCP).Methods:Levator palpebrae superiors muscle specimens from 102 eyes of 68 patients with SCP who received levator palpebrae superiors muscle shortening surgery at Wuhan Aier Hankou Eye Hospital from August 2018 to October 2019 were collected as the observation group.According to the severity of ptosis, the specimens were divided into three groups, coverage ≤4 mm group (n=35), coverage >4 mm to ≤6 mm group (n=30), and coverage >6 mm group (n=37). Fresh levator palpebrae superiors muscle tissues from 8 normal donors in Aier Eye Bank of Wuhan Red Cross were selected as the control group.All specimens were performed with Masson trichrome staining and immunohistochemical staining for α-smooth muscle actin (α-SMA), and ImageJ software was used to measure the collagen fiber area ratio, skeletal muscle fiber area ratio and the integrated absorbance (IA) value of α-SMA.Seventeen specimens (2 from the control group, 5 from coverage ≤4 mm group/coverage >4 mm to ≤6 mm group/coverage >6 mm group) were observed with a transmission electron microscope (TEM). This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Wuhan Aier Hankou Eye Hospital (No.HKAIER2018IRB-005-01). All patients and their legal guardians were well informed about the treatment method and the purpose of sampling and voluntarily signed informed consent.Results:Compared with the control group, the skeletal muscle fiber was reduced in number and was in disordered arrangement, and the striation of some muscle fibers disappeared, and hyperplastic fibrous connective tissue was found in intercellular substances in the observation group.The collagen fiber area ratio of the coverage ≤4 mm group, coverage >4 mm to ≤6 mm group, coverage >6 mm group were significantly higher than that of the control group, and the skeletal muscle fiber area ratio of the three groups was significantly lower than that of the control group (all at P<0.008 3). There were more smooth muscle fibers and positive expression of α-SMA found in the specimens of the observation group.The IA value of α-SMA of the coverage ≤4 mm group, coverage >4 mm to ≤6 mm group, coverage >6 mm group was 7 195.28(5 935.69, 14 058.29), 55 584.18(33 861.88, 80 419.32), 166 507.76(119 121.95, 187 890.86), respectively, which were all higher than 5 543.03(4 867.67, 8 312.02) of the control group, among which, there were statistically significant differences between the control group and the coverage >4 mm to ≤6 mm group, coverage >6 mm group (both at P<0.008 3). Abundant organelles and some damaged mitochondria were found in smooth muscle cytoplasm in the observation group with a TEM.But no characteristic structure of smooth muscle cells such as dense patch and dense body was detected.Conclusions:There are abnormal smooth muscle cells in the levator palpebrae superiors muscle of SCP patients, and the dysgenesis of the levator palpebrae superiors muscle may be related to this abnormal muscle cell.

Objective To discuss the optimal operation mode and operation path in minimally invasive technique for living donor nephrectomy.Methods From September 2013 to August 2015, 68 living donor nephrectomy was retrospectively reviewed. Thirty-one patients were performed with robotic-assisted laparoscopic living donor nephrectomy(robotic group), twenty-nine patients underwent totally retroperitoneal laparoscopic living donor nephrectomy(non hand assisted group),and eight patients were performed with hand assisted retroperitoneal laparoscopic living donor nephrectomy(hand assisted group). Operation time, warm ischemia time, intraoperative hemorrhage volume, hospitalization time, complications and preoperative and postoperative serum creatinine value of the recipients between the two groups were compared.Results The operations of three groups were all performed successfully. Intraoperative hemorrhage volume in the three groups were(39±15)ml,(62±37)ml and(53±19)ml, and there were significant differences between these groups(P<0.05). But hospitalization time ,operation time, warm ischemia time and complications occurred rate in the three groups had no significant difference(P>0.05). In robotic group,2 donors occurred with splenic injury during operation and 1 donor was detected with hemorrhage after operation. In non-hand assisted group, 1 donor occurred with urinary tract infection, 1 donor occurred with external iliac vein thrombosis. In hand assisted group 1 donor was detected with wound fat liquefaction after operation. All the donors were followed up for more than 9 months, no hypertension, proteinuria and renal dysfunction complications were detected. The blood creatinine in three groups of recipients after operation of 5th day and 28th day were(118±26)μmol/L, (130±33)μmol/L,(128±41)μmol/L and(114±17)μmol/L,(116±34)μmol/L,(115±29)μmol/L, respectively, and there was no statistical difference(P>0.05).Conclusions Minimally invasive technique for living donor nephrectomy is beneficial to patients' recovery. Surgery doctors should combine personal experience and the hospital's hardware conditions and other factors. The principle is to ensure the donor's safety and to balance the interests of the donor and the recipient, to choose their own most skilled way of surgery.

Objective:To invetigate the influencing factors and clinical significance of liver function damage (LFD) in patients diagnosed with Corona Virus Disease 2019 (COVID-19).Methods:The retrospective case-control study was conducted. The clinicopathological data of 51 patients with COVID-19 who were admitted to the Sino-French New City Branch of Tongji Hospital Affiliated to Huazhong University of Science and Technology by the 5th group assisting team from the First Hospital of Jilin University from February 9th to 27th in 2020 were collected. There were 27 males and 24 females, aged from 36 to 86 years, with an average age of 68 years. The treatment modality was according to the diagnostic and therapeutic guideline for COVID-19 (Trial 6th edition) issued by National Health Commission. Observation indicators: (1) clinical data of patients; (2) analysis of liver function index and treatment of LFD; (3) analysis of influencing factors for LFD. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were described as M (range). Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. The Logistic regression method was used for univariate analysis. Results:(1) Clinical data of patients: of the 51 patients, 21 were classified as ordinary type of COVID-19, 19 as severe type and 11 as critical type. In terms of medical history, 31 patients suffered from more than or equal to one kind of chronic disease, 20 had no history of chronic disease. Thirteen patients had the drinking history and 38 had no drinking history. Seven patients were hepatitis positive and 44 were hepatitis negative. Five patients had septic shock at admission, 5 had systemic inflammatory response syndrome (SIRS), and 41 had neither shock nor SIRS. The body mass index (BMI), time from onset to admission, temperature, heart rate, respiratory rate of the 51 patients were (24±3)kg/m 2, (13±5)days, 36.5 ℃ (range, 36.0-38.1 ℃), 82 times/minutes (range, 50-133 times/minutes), 20 times/minutes (range, 12-40 times/minutes). The white blood cell count, level of creatinine, and level of b-type natriuretic peptide within 24 hours after admission were 6.3×10 9/L [range, (2.2-21.7)×10 9/L], 75 μmol/L (range, 44-342 μmol/L), 214 ng/L (range, 5-32 407 ng/L). (2) Analysis of liver function index and treatment of LFD: the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), direct bilirubin (DBil), indirect bilirubin (IBil), activated partial thromboplastin time (APTT) and prothrombin time (PT) were 31 U/L (range, 7-421 U/L), 29 U/L (range, 15-783 U/L), 36 U/L (range, 13-936 U/L), 76 U/L (range, 41-321 U/L), 4.9 μmol/L (range, 2.6-14.3 μmol/L), 5.8 μmol/L (range, 2.6-23.9 μmol/L), 37.2 s (range, 30.9-77.1 s), 13.9 s (range, 12.5-26.7 s), respectively. The percentages of cases with abnormal ALT, AST, GGT, ALP, DBil, IBil, APTT and PT were 47.1%(24/51), 47.1%(24/51), 35.3%(18/51), 13.7%(7/51), 7.8%(4/51), 2.0%(1/51), 21.6%(11/51), and 19.6%(10/51), respectively. Of the 51 patients, LFD was detected in 10 patients classified as ordinary type, in 9 patients as severe type, and in 10 as critical type, respectively. In the 51 patients, 1 of 22 patients with normal liver function developed respiratory failure and received mechanical ventilation within 24 hours after admission, while 9 of 29 patients with abnormal liver function developed respiratory failure and received mechanical ventilation, showing a significant difference between the two groups ( χ2=5.57, P<0.05). (3) Analysis of influencing factors for LFD. Results of univariate analysis showed that clinical classification of COVID-19 as critical type was a related factor for LFD of patients ( odds ratio=10.000, 95% confidence interval: 1.050-95.231, P<0.05). Conclusions:COVID-19 patients with LFD are more susceptible to develop respiratory failure. The clinical classification of COVID-19 as critical type is a related factor for LFD of patients.

OBJECTIVE: To explore the management model of smart pharmacy under the background of “Internet+TCM”, and to promote the improvement of the work and service quality of smart pharmacy. METHODS: The information platform and internal organization of smart pharmacy in our hospital were combined; the supervision and management of smart pharmacy and the establishment of quality control system in smart pharmacy were summarized and the development and supervision effectiveness of smart pharmacy in our hospital were evaluated. RESULTS: Our hospital established the information platform on the basis of the “Internet+TCM”. Hospital information setting were divided into online and offline. The prescriptions that were not suitable for online handling decoction and distribution service were clearly defined and the system locking settings were set up to realize effective information transmission from hospital to smart pharmacy. The service platform of smart pharmacy were set up including electronic prescription circulation system, whole-course prescription barcode recognition management system, electronic prescription audit and dispensing system, intelligent decoction control management system, smart pharmacy distribution management system, etc. It had realized seamless connection of information between smart pharmacy and patients. The internal organization included six departments: prescription audit center, dispensing center, decoction center, individualized preparation production center, logistics center and customer service center. Our hospital conducted daily supervision and management of the entire work process of the smart pharmacy from aspect of hospital management and pharmacy management. The internal service quality of smart pharmacy could be controlled by quality control system of prescription reviewing center, dispensing center, decocting center, individualized preparation center, logistics center and customer service center and pharmaceutical personnel training mechanism in smart pharmacy. Since the start of the smart pharmacy in June 2015, the number of people receiving the services of smart pharmacy had increased significantly, and the types of services and service opportunities for patients had added; the distribution service had added, and the service of individualized preparation processing and distribution had also added. Moreover, the service capacity of smart pharmacy far exceeded the demand of our hospital, and other medical institutions could share the platform of smart pharmacy. By simply counting the situation in our hospital, the average number of daily prescription increased from 387 in Jun.-Dec. of 2015 to 1 433 in 2018; the error rate showed a downward trend, among which the abnormal rate of prescription reviewing, the dispensing error rate, the decoction error rate and customer service complaints rate decreased from 2.10%, 0.13%, 0.52%, 0.13% in Jun.-Dec. of 2015 to 0.45%, 0.05%, 0.27%, 0.04% in 2018; total timely investment rate in logistics increased from 93.20% in Jun.-Dec. of 2015 to 97.06% in 2018. At present, the existing information platform, internal organization, quality control system and supervision system could ensure the orderly operation of smart pharmacy and could ensure the quality of drugs, decoction and distribution. CONCLUSIONS: However, the development of smart pharmacy in our hospital is still in its infancy. In the future, it is still necessary to strengthen the construction of information software and hardware, standardize the operation of various links, strengthen personnel training, establish an effective quality control system and explore more objective supervision mechanisms.
