Objective To investigate the clinical value of serum insulin-like growth factor-1 (IGF-1),insulin-like growth factor-binding protein-3 (IGFBP-3) and mean height standard deviation score(HtSDS) in recombinant human growth hormone (rhGH)-treated small for gestational age (SGA) children.Methods 32 cases of SGA failed of catch-up growth were subcutaneously injected with rhGH every night before bed at a dose of 0.15-0.20u· kg-1 · d-1.And the variation of serum IGF-1,IGFBP-3,HtSDS,body height and growth velocity (GV) were monitored at 3,6,9 and 12 months of the treatment and compared.Results The GV (cm/years) increased to (12.4 ± 3.2),(11.0 ± 2.3),(10.1 ± 3.5),(9.4 ± 1.8) versus (4.1 ± 0.5) before treatment,suggesting a significant catch-up growth after treatment (F =51.35,P < 0.01).Accordingly,HtSDS increased to (-2.55 ± 0.73),(-2.39 ± 0.65),(-2.21 ± 0.58),(-2.09 ± 0.94) versus (-2.81 ± 0.64),suggesting that height gaps were reduced compared to the normal children of the same age and sex after rhGH treatment (F =4.99,P <0.01).The serum levels of IGF-1,IGFBP-3 were significantly increased compared to pre-treatment (F =34.52,14.04,all P < 0.01),especially for serum IGF-1,which maintained at a high level after 3 months of treatment and up to peak after 6 months.However,the ratio of IGF-1/IGFBP-3 showed no increase after treatment (F =1.82,P > 0.05).There was a significant positive correlation between the serum level of IGF-1 and △HtSDS after the rhGH treatment within six months (r3 =0.72,r6 =0.91),while there was no correlation between them after 9 months (r9 =0.26,r12 =0.33).There were no serious adverse events during the rhGH treatment.Conelusion The serum levels of IGF-1,IGFBP-3 were significantly increased after the rhGH treatment,especially for serum IGF-1.There was a significant positive correlation between the serum level of IGF-1 and △HtSDS within six months,but not after 9 months.The rhGH treatment could be a safe and effective strategy for SGA children.

Objective:To establish autoverification rules for coagulation tests in multicenter cooperative units, in order to reduce workload for manual review of suspected results and shorten turnaround time (TAT) of test reports, while ensure the accuracy of results.Methods:A total of 14 394 blood samples were collected from fourteen hospitals during December 2019 to March 2020. These samples included: Rules Establishment Group 11 230 cases, including 1 182 cases for Delta check rules; Rules Validation Group 3 164 cases, including 487cases for Delta check; Clinical Application Trial Group 77 269 cases. Samples were analyzed for coagulation tests using Sysmex CS series automatic coagulation analyzers, and the clinical information, instrument parameters, test results, clinical diagnosis, medication history of anticoagulant and other relative results such as HCT, TG, TBIL, DBIL were summarized; on the basis of historical data, the 2.5 and 97.5 percentile of all data arranged from low to high were initially accumulated; on the basis of clinical suggestions, critical values and specific drug use as well as relative guidelines, autoverification rules and limits were established.The rules were then input into middleware, in which Stage I/Stage II validation was done. Positive coincidence, negative coincidence, false negative, false positive, autoverification pass rate, passing accuracy (coincidence of autoverification and manual verification) were calculated. Autoverification rules underwent trial application in coagulation results reports.Results:(1) The autoverification algorisms involve 33 rules regarding PT/INR, APTT, FBG, D-dimer, FDP,Delta check, reaction curve and sample abnormalities; (2)Autoverification Establishment Group showed autoverification pass rate was 68.42% (7 684/11 230), the false negative rate was 0%(0/11230), coincidence of autoverification and manual verification was 98.51%(11 063/11 230), in which positive coincidence and negative coincidence were respectively 30.09% (3 379/11 230) and 68.42%(7 684/11 230); Autoverification Validation Group showed autoverification pass rate was 60.37%(1 910/3 164), the false negative rate was 0%(0/11 230), coincidence of autoverification and manual verification was 97.79%(3 094/3 164), in which positive coincidence and negative coincidence were respectively 37.42%(1 184/3 164) and 60.37%(1 910/3 164); (3) Trialed implementation of these autoverification rules on 77 269 coagulation samples showed that the average TAT shortened by 8.5 min-83.1 min.Conclusions:This study established 33 autoverification rules in coagulation tests. Validation showedthese rules could ensure test quality while shortening TAT and lighten manual workload.

Objective:
To understand the etiology of hepatopathy of unknown etiology in patients undergoing liver biopsy.
Methods:
Demographic data and pathological examination reports of patients with hepatopathy of unknown etiology who underwent liver biopsy examination at outpatient and inpatient of the Second Hospital of Nanjing between January 2017 and June 2018 were retrospectively collected. All liver histopathological sections combined with clinical and pathological features based on liver biopsy examinations were diagnosed by a reputed clinician and a pathologist.
Results:
A total of 470 cases with hepatopathy of unknown etiology who underwent liver biopsy were enrolled. Of these, 425 cases (90.4%) had a definite diagnosed disease after comprehensive analysis of pathological and clinical data. The diagnosis of hepatopathy of unknown etiology included 11 diseases: 90 cases with autoimmune hepatitis had autoimmune liver disease (19.1%), 38 cases had primary biliary cholangitis (8.1%), 43 cases with overlap syndrome of autoimmune hepatitis had primary biliary cholangitis (9.1%), 118 cases had drug-induced liver injury (25.1%), 75 cases had nonalcoholic fatty liver disease (NAFLD) (16.0%), 12 cases had alcoholic liver disease (2.6 cases) %), 15 cases (3.2%) had vascular liver disease, 7 cases (1.5%) had hereditary metabolic liver disease, 5 cases (1.1%) had other systemic diseases, 16 cases (3.4%) had more than two kinds of liver diseases, and 6 cases (1.3%) had others rare liver diseases.
Conclusion
Over 90% cause of the hepatopathy of unknown etiology in the long run can be determined, and the main causes are autoimmune liver disease, drug-induced liver injury, and nonalcoholic fatty liver disease, which needs multidisciplinary cooperation to diagnose, and clinicians need to master the basic and clinical knowledge of liver diseases as well as liver pathology, hepatobiliary imaging, and genetics.
