ObjectiveTo explore the syndrome elements and evolving patterns of patients with hepatitis B virus-related acute on chronic liver failure （HBV-ACLF） at different stages. MethodsClinical information of 1,058 hospitalized HBV-ACLF patients， including 618 in the early stage， 355 in the middle stage， and 85 in the late stage， were collected from 18 clinical centers across 12 regions nationwide from January 1， 2012 to February 28， 2015. The “Hepatitis B-related Chronic and Acute Liver Failure Chinese Medicine Clinical Questionnaire” were designed to investigate the basic information of the patients， like the four diagnostic information （including symptoms， tongue， pulse） of traditional Chinese medicine （TCM）， and to count the frequency of the appearance of the four diagnostic information. Factor analysis and cluster analysis were employed to determine and statistically analyze the syndrome elements and patterns of HBV-ACLF patients at different stages. ResultsThere were 76 four diagnostic information from 1058 HBV-ACLF patients， and 53 four diagnostic information with a frequency of occurrence ≥ 5% were used as factor analysis entries， including 36 symptom information， 12 tongue information， and 5 pulse information. Four types of TCM patterns were identified in HBV-ACLF， which were liver-gallbladder damp-heat pattern， qi deficiency and blood stasis pattern， liver-kidney yin deficiency pattern， and spleen-kidney yang-deficiency pattern. In the early stage， heat （39.4%， 359/912） and dampness （27.5%， 251/912） were most common， and the pattern of the disease was dominated by liver-gallbladder damp-heat pattern （74.6%， 461/618）； in the middle stage， dampness （30.2%， 187/619） and blood stasis （20.7%， 128/619） were most common， and the patterns of the disease were dominated by liver-gallbladder damp-heat pattern （53.2%， 189/355）， and qi deficiency and blood stasis pattern （27.6%， 98/355）； and in the late stage， the pattern of the disease was dominated by qi deficiency （26.3%， 40/152） and yin deficiency （20.4%， 31/152）， and the patterns were dominated by qi deficiency and blood stasis pattern （36.5%， 31/85）， and liver-gallbladder damp-heat pattern （25.9%， 22/85）. ConclusionThere are significant differences in the distribution of syndrome elements and patterns at different stages of HBV-ACLF， presenting an overall trend of evolving patterns as "from excess to deficiency， transforming from excess to deficiency"， which is damp-heat → blood stasis → qi-blood yin-yang deficiency.

Objective To identify factors associated with gastrointestinal heat retention in preschool children,and to provide a foundational understanding for future clinical investigations. Methods A case-control study was performed,which involved children from kindergartens in the Longgang District of Shenzhen City,Guangdong Province,from May to July 2021. Using the Children's Gastrointestinal Heat Retention Diagnostic Self-assessment Scale,subjects were allocated into a case group (children diagnosed with gastrointestinal heat retention) and a control group (children without this condition). An online survey was used to collect data on dietary behaviors,caregivers' feeding behaviors,early antibiotic use,daily routines,and birth conditions. SPSS 27.0 software was used to facilitate precise sociodemographic matching and paired logistic regression analysis to explore the association between gastrointestinal heat retention and the above factors. Results From the analysis of 51,252 matched cases,the study found that several factors contributed to an increased risk of gastrointestinal heat retention. These factors included reduced food intake compared to peers,reports of picky eating by caregivers,distractions during meals,pronounced dietary preferences,disinterest in food,meal durations ≥ 25 min,reluctance to sample new foods,consistent refusal of specific food types for over one month,irregular meal locations,coercive feeding practices,use of micronutrient supplements,allowing children too much freedom in food choice,persuading children to eat,infrequent encouragement to experiment with new foods,early antibiotic introduction,inadequate sleep,and premature birth (P<0.05). In contrast,exclusive breastfeeding in the first six months,engagement in moderate to massive physical activity,and regular napping patterns were associated with a reduced risk of gastrointestinal heat retention (P<0.05). Conclusion The suboptimal dietary habits,improper feeding practices,insufficient physical activity,inadequate sleep,and premature antibiotic exposure may be significant risk factors for gastrointestinal heat retention. Future research dedicated to unraveling the cause of gastrointestinal heat retention should prioritize these elements.

Objective:To analyze the factors influencing functional recovery after surgery of calcaneal fracture.Methods:A retrospective analysis was performed in 1,080 eligible patients with calcaneal fracture who had been admitted to The Third Hospital of Hebei Medical University from January 1, 2018 to December 31, 2020. They were 931 males and 149 females with a mean age of 43.0 years. By the Sanders classification, there were 107 cases of type Ⅰ, 343 cases of type Ⅱ, 471 cases of type Ⅲ and 159 cases of type Ⅳ. Multiple linear regression model was used to screen out the main relevant factors affecting the postoperative functional recovery by analyzing the 18 factors which might influence the postoperative functional recovery like gender, age, Sanders type, occupation, body mass index, season, cause, hospital stay, operation method, internal fixation, preoperative combined injury, preoperative complication, anesthesia, attendance to rehabilitation institution, incision selection, waiting time, preoperative blister and reduction quality.Results:All the 1,080 patients were followed up for 17.5 months on average. The mean Creighton-Nebraska score at the last follow-up was 88.4. The univariate analyses showed statistically significant differences in the Creighton-Nebraska score among patients with different gender, age group, Sanders type, occupation, injury cause, surgical method, preoperative combined injury, incision selection and reduction quality ( P<0.05). Multiple linear regression model analysis resulted in the following regression equation: Y=107.408-4.013×gender-7.101×age-1.214×Sanders type-1.606×incision selection. Conclusions:The factors which influence the functional recovery after surgery of calcaneal fracture may be gender, age, fracture type and incision selection; the functional recovery score after surgery of calcaneal fracture may be low for female senior patients with type Ⅳ fracture and a large L-shaped incision.

Objective: To evaluate the effect of continuous embedding on the improvement of mild epicanthus by studying the change of intercanthal distance and inner canthus angle in patients perioperatively. Methods: In this study, 34 patients with single eyelid and mild epicanthus were analyzed retrospectively. Procedure included small incisions combined with continuous embedding double eyelid surgery. The photo of eyes was taken in the front position preoperatively and postoperatively. Before operation, 3-months, 6 months-after operation, intercanthal distance and inner canthal angle of both eyes were measured by Photoshop CS6. The iris diameter scale was used to measure intercanthal distance. Results: Preoperative intercanthal distance (PRICD) values were 65.96±4.94 (iris diameter scale), 3-month-postoperative intercanthal distance (3POICD) values were 63.43±5.04 (iris diameter scale), and 6-month-postoperative intercanthal distance (6POICD) values were 63.82±5.02 (iris diameter distance). Preoperative inner-canthal angle of the left eye (PRCAL) values were (47.51±4.28)°, preoperative inner-canthal angle of the right eye (PRCAR) values were (47.30±4.55)°, 3-month-preoperative inner-canthal angle of the left eye (3POCAL) values were (49.53±5.15)°. 3-month-preoperative inner-canthal angle of the right eye (3POCAR) values were (49.24±4.86)°, 6 month-postperative inner-canthal angle of the left eye (6POCAL) values were (49.48±4.74)°, and 6 month-postperative inner-canthal angle of the right eye (6POCAR) values were (48.99±4.55)°. The difference between PRICD and 3POICD, PRICD and 6POICD, PRCAL and 3POCAL, PRCAL and 6POCAL, PRCAR and 3POCAR, PRCAR and 6POCAR were statistically significant (t=6.432, 6.307, -2.882, -3.188, -2.516, -2.248, P<0.05). The difference between 6POICD and 3POICD was statistically significant (t=4.047, P<0.05); moreover, the mean value of 6POICD was larger than the mean value of 3POICD. There was no significant difference between 6POCAL and 3POCAL, and 6POCAR and 3POCAR (t=0.352, P>0.05). Conclusions According to the result of the study, the continuous embedding method has a certain effect on shortening the intercanthal distance and changing the inner canthal angle. It is inferred that the continuous embedding method has a certain effect on the improvement of mild epicanthus.

Objective To analyze the clinical and electrophysiological features in a family with spinal muscular atrophy (SMA), and assess the probable causative gene mutations for the family. Methods To identify the nosogenesis of the proband with weakness and atrophy in the double lower proximal limbs, clinical data of his 12 family members were collected, and the proband and his mother were selected for clinical examinations, including laboratory tests, electromyogram (EMG), F-wave, H-reflex, X-ray of the spine and double lower limbs, brain and spinal cord magnetic resonance imaging, etc. Moreover, human whole exome sequencing was performed on blood sample from the proband, then its deleterious effects were assessed according to the Standards and guidelines for the interpretation of sequence variants, a joint consensus recommendation of the American College of Medical Genomics (ACMG) and the Association for Molecular Pathology (AMP). Subsequently, the strong pathogenic mutation was validated by Sanger sequencing. Results Familial investigation showed seven of 12 family members presented with weakness in the double lower proximal limbs. Among them, three had the main manifestation of atrophy in the double lower proximal limbs, one had high arched foot as the main presentation, and the others had weakness in the double lower proximal limbs. EMG studies showed the abnormal results in the anterior horn of the spinal cord. The strong pathogenic mutation in DYNC1H1 gene (exon8, c.2327C＞T, p.P776L) was identified from the proband according to ACMG and AMP guidelines. Sanger sequencing revealed six patients had this variant and it was passed mainly from his maternal grandmother. Conclusions A pathogenic mutation of the DYNC1H1 p.P776L in six Chinese pedigrees which cosegregated with SMA was identified. There existed individual differences in clinical presentations. This finding may have important implications for the study of SMA in Chinese patients.

Objective: To analyze the gene mutations in the patients with myelodysplastic syndromes (MDS). Methods: Forty-seven patients with MDS newly diagnosed in Xiyuan Hospital, China Academy of Chinese Medical Sciences from January 2016 to July 2017 were enrolled. NGS 127-gene panel was used to detect the gene mutations, and the relationship between the gene mutations and the clinicopathological features was also analyzed. Results: Thirty-one (66.0 %) cases had gene mutations in 47 patients with MDS, and 23 gene mutations were detected with clinical significances. There were 7 mutant genes with a mutation frequency over 5 % in the population, including U2AF1 (23.4 %), SF3B1 (12.8 %), ASXL1 (10.6 %), TET2 (8.5 %), BCOR (8.5 %), TP53 (8.5 %) and DNMT3A (6.4 %) in turn. Among 31 patients with gene mutations, 16 (51.6 %) patients had ≥ 2 synergistic mutations, and 12 cases had synergistic mutations in different genetic functional groups, which was higher than that in same genetic functional groups (4 cases). There was a tendency of coexistence in IDH2-KRAS, IDH2-SRSF2, IDH2-STAG2, KRAS-SRSF2, KRAS-STAG2, RUNX1-PHF6, EZH2-ASXL1, EZH2-ZRSR2, and NPM1-NRAS (all P < 0.05). The variant allele frequency (VAF) of signaling pathway related genes including JAK2, KRAS, NRAS, SH2B3 was low in general and in a sub-clone status. JAK2 gene mutation was observed in 1 case with MDS-U. SH2B3 gene mutation was observed in a patient with very poor prognosis of karyotype. SETPB1 and EZH1 gene mutations were observed in two patients with high-risk revised international prognostic scoring system (IPSS-R). Conclusions The common mutated genes include U2AF1, SF3B1, ASXL1 and TET2. The genes in different genetic functional groups tend to synergistic mutations. Gene mutations can be used to predict the prognosis of diseases and become the target in the treatment of MDS.

Objective To investigate the safety and effectiveness of mesh and non-mesh techniques in laparoscopic repair of large hiatal hernias (LRLHH).Methods A retrospective clinical controlled study of mesh and non-mesh techniques in LRLHH form January 2006 to August 2014 was performed.Results A total of 83 and 36 patients were recruited to mesh and non-mesh group respectively.There were no significant differences in operation time,operation bleeding volume,hospitalization time or complications between the two groups.Main symptoms were significantly improved during the postoperative long-term follow-up in both groups.The improvement of dysphagia in mesh group showed no significant difference [22.9％ (19/83) VS 12.0％ (10/83),P=0.066],however,non-mesh group showed significant difference [30.6％ (11/36) VS 5.6％ (2/36),P=0.006].Rate of dysphagia alleviation in non-mesh group was significantly higher than that in mesh group [25.0％ (9/36) VS 10.8％ (9/83),P =0.048].Mesh-related complications of esophageal erosions occurred in 5 patients (6.0％) in mesh group,including esophageal stenosis in 3 patients,esophageal-cardiac stricture in 1 patient.Recurrent hernia occurred in 1 patient (1.2％) in mesh group and 3 patients (8.3％) in non-mesh group (P =0.082).Conclusion LRLHH with mesh should be individualized.The use of mesh in LRLHH reduces the recurrence rate,but may lead to some complications.

OBJECTIVETo investigate the facial aging analysis of 1200 Han adult people in Dalian with iris diameter, so as to provide reference for facial rejuvenation in Han people.

METHODS1200 facial digital photographs from the second-generation ID card of China were stratified randomly selected as the research sample, excluding facial deformity, tattooing eyebrow, tattooing lid margin, ptosis, lip grain and eyebrow deformity cases, as well as the cases whose join point of upper eyelid and lower eyelid not exposed at the nasal side. These photos were divided into six cohorts: female aged 18, 38, and 68 years old; and male aged 18, 38, and 68 years old, with 200 cases in each cohort. The individual iris diameter was divided into 20 equal parts in each photograph, with each part marked one unit as individual iris diameter ruler. Ten values were made from a horizontal plane between the medial canthus to ten points at one face ( the line between two medial canthus is used as the horizontal line, circumocular and facial soft tissue were measured with individual iris diameter ruler on the photographs), then the results were analyzed with Adobe Photoshop software.

RESULTSThere are statistically significant differences in eyebrow height (36.42 ± 4.22 unit in 18 years old male group, 40.22 ± 6.90 unit in 38 years old male group, 34.83 ± 9.39 unit in 68 years old male group; 37.59 ± 6.72 unit in 18 years old female group, 41.09 ± 5.15 unit in 38 years old female group, 36.84 ± 9.45 unit in 68 years old female group), palpebral fissure height, physiognomic external canthus height, palpebral fissure width, pupil height and other items (P < 0.05).

CONCLUSIONS(1) The brow position rises to the peak level at middle age (38 years old group), then drops down gradually with aging. (2) The physiognomic external canthus moves towards the nasal side and caudal side with aging. (3) Eyeball moves towards caudal side with aging. (4) The soft tissue around bilateral angle of mouth, nasal tip and submaxilla moves towards caudal side with aging. (5) The measurement of individual iris diameter ruler can apply to analyze the aging changes of facial soft tissue, and is more suitable for the case when facial photographs are taken at different distances.
