Abstract
Several observational studies have reported an association between obesity and primary liver cancer (PLC), while the causality behind this association and the comparison of the risk effects of different obesity indicators on PLC remain unclear. In this study, we performed two-sample Mendelian randomization (MR) analyses to assess the associations of genetically determined liver fat, visceral adipose tissue (VAT), and body mass index (BMI) with the risk of PLC. The summary statistics of exposures were obtained from two genome-wide association studies (GWASs) based on the UK Biobank (UKB) imaging cohort and the Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort. GWAS summary statistics for PLC were obtained from FinnGen consortium R7 release data, including 304 PLC cases and 218 488 controls. Inverse-variance weighted (IVW) was used as the primary analysis, and a series of sensitivity analyses were performed to further verify the robustness of these findings. IVW analysis highlighted a significant association of genetically determined liver fat (OR per SD increase: 7.14; 95% CI: 5.10-9.99; P = 2.35E-30) and VAT (OR per SD increase: 5.70; 95% CI: 1.32-24.72; P = .020) with PLC but not of BMI with PLC. The findings were further confirmed by a series of MR methods. No evidence of horizontal pleiotropy between these associations existed. Our study suggested that genetically determined liver fat and VAT rather than BMI were associated with an increased risk of PLC, which suggested that visceral fat distribution is more predictive of the clinical risk of PLC than common in vitro measures.

Abstract
Objective: Analysis and investigation of pathogenic characteristics of polymyxin-and carbapenem-resistant Klebsiella pneumoniae (PR-CRKP). Methods: A total of 23 PR-CRKP strains isolated from clinical specimens from the General Hospital of Southern Theater Command from March 2019 to July 2021 were retrospectively collected, Whole-genome sequencing was performed on 23 PR-CRKP strains, resistance genes were identified by comparison of the CARD and the ResFinder database, high-resolution typing of PR-CRKP strains was analyzed by core genomic multilocus sequencing (cgMLST) and single nucleotide polymorphism (SNP); polymyxin resistance genes were determined by PCR and sequencing. Results: All PR-CRKP strains were KPC-2 producing ST11 types. cgMLST results showed that the evolutionary distance between the PR-CRKP strains and Klebsiella pneumoniae in mainland China was 66.44 on average, which is more closely related than foreign strains; the 23 PR-CRKP strains were divided into 3 main subclusters based on SNP phylogenetic trees, with some aggregation among Clade 2-1 in the isolation department and date. The two-component negative regulatory gene mgrB has seven mutation types including point mutations, different insertion fragments and different insertion positions. Conclusion: The close affinity of PR-CRKP strains indicate the possibility of nosocomial clonal transmission and the need to strengthen surveillance of PR-CRKP strains to prevent epidemic transmission of PR-CRKP.

Abstract
Objective: To examine the clinical effect of auxiliary liver transplantation with ultra-small volume graft in the treatment of portal hypertension. Methods: Twelve cases of portal hypertension treated by auxiliary liver transplantation with small volume graft at Liver Transplantation Center,Beijing Friendship Hospital, Capital Medical University between December 2014 and March 2022 were studied retrospectively. There were 8 males and 4 females,aged 14 to 66 years. Model for end-stage liver disease scores were 1 to 15 points and Child scores were 6 to 11 points. The grafts was derived from living donors in 9 cases,from split cadaveric donors in 2 cases,from whole cadaveric liver of child in 1 case. The graft recipient body weight ratios of 3 cadaveric donor livers were 0.79% to 0.90%, and of 9 living donor livers were 0.31% to 0.55%.In these cases, ultra-small volume grafts were implanted. The survivals of patient and graft, complications, portal vein blood flow of residual liver and graft, abdominal drainage and biochemical indexes of liver function were observed. Results: All the grafts and patients survived. Complications included outflow tract torsion in 2 cases, acute rejection in 1 case, bile leakage in 1 case, and thyroid cancer at the later stage of follow-up in 1 case, all of which were cured. The torsion of outflow tract was attributed to the change of anastomotic angle after the growth of donor liver. After the improvement of anastomotic method, the complication did not recur in the later stage. There was no complication of portal hypertension. The measurement of ultrasonic portal vein blood flow velocity showed that the blood flow of residual liver decreased significantly in the early stage after operation, and maintained a very low blood flow velocity or occlusion in the long term after operation, and the blood flow of transplanted liver was stable. Conclusions: Auxiliary liver transplantation can implant ultra-small donor liver through compensation of residual liver. This method may promote the development of living donor left lobe donation and split liver transplantation. However, the auxiliary liver transplantation is complex, and it is difficult to control the complications. Therefore, this method is currently limited to centers that are skilled in living related liver transplantation and that have complete ability to monitor and deal with complications.

Abstract
The compressed ultrafast photography (CUP) can capture non-repetitive time-evolving events at 7 × 1013 fps, which is anticipated to find a diverse range of applications in physics, biomedical imaging, and materials science. The feasibility of diagnosing ultrafast phenomenon of Z-pinch by using the CUP has been analyzed in this article. Specifically, a dual-channel CUP design has been adopted for acquiring high quality reconstructed images and the strategies of identical masks, uncorrelated masks, and complementary masks have been compared. Furthermore, the image of the first channel was rotated by 90° to balance the spatial resolution between the sweep direction and the non-sweep direction. Both five synthetic videos and two simulated Z-pinch videos were chosen as the ground truth to validate this approach. The average peak signal to noise ratio of the reconstruction results is 50.55 dB for the self-emission visible light video and 32.53 dB for the laser shadowgraph video with unrelated masks (rotated channel 1). The simulation results show that the time-space-evolving process of plasma distribution can be well retold, and the phenomenon of plasma instability can be accurately diagnosed by the dual-channel CUP with unrelated masks (rotated channel 1). This study may promote the practical applications of the CUP in the field of accelerator physics.

Abstract
Hepatocyte transplantation is considered a promising alternative treatment to liver transplantation. Although the safety and efficacy of hepatocyte transplantation in the treatment of acute liver failure and certain inherited metabolic diseases of the liver have been validated in many clinical trials, clinical hepatocyte transplantation still faces many problems and limitations, such as a shortage of high-quality donor organs, reduced cell viability after cryopreservation, low cell implantation and proliferation rates, and allogeneic hepatocyte rejection. This article reviews the latest basic research and clinical application progress in hepatocyte transplantation.

Abstract
Objective: Propionic acidemia is a rare inherited metabolic disorder caused by propionyl CoA carboxylase (PCC) deficiency. This study aims to analyze the clinical characteristics and gene variations of Chinese patients with propionic acidemia, and to explore the correlation between clinical phenotypes and genotypes. Methods: Single-center, retrospective and observational study. Seventy-eight patients of propionic acidemia (46 males and 32 females) from 20 provinces and autonomous regions were admitted from January 2007 to April 2022. Their age of initial diagnosis ranged from 7 days to 15 years. The clinical manifestations, biochemical and metabolic abnormalities, genetic variations, diagnosis, treatment and outcome were studied. Chi-Square test or Mann-Whitney U test were used for statistical analysis. Results: Among 78 cases, 6 (7.7%) were identified by newborn screening; 72 (92.3%) were clinically diagnosed after onset, and the age of onset was 2 hours after birth to 15 years old; 32 cases had early-onset disease and 40 cases had late-onset disease. The initial manifestations included lethargy, hypotonia, vomiting, feeding difficulties, developmental delay, epilepsy, and coma. Among the 74 cases who accepted gene analysis, 35 (47.3%) had PCCA variants and 39 (52.7%) had PCCB variants. A total of 39 PCCA variants and 32 PCCB variants were detected, among which c.2002G>A and c.229C>T in PCCA and c.838dupC and c.1087T>C in PCCB were the most common variants in this cohort. The variants c.1228C>T and c.1283C>T in PCCB may be related to early-onset type. The variants c.838dupC, c.1127G>T and c.1316A>G in PCCB, and c.2002G>A in PCCA may be related to late-onset disease. Six patients detected by newborn screening and treated at asymptomatic stage developed normal. The clinically diagnosed 72 cases had varied complications. 10 (12.8%) cases of them died. 62 patients improved after metabolic therapy by L-carnitine and diet. Six patients received liver transplantation because of recurrent metabolic crisis. Their clinical symptoms were markedly improved. Conclusion: The clinical manifestations of propionic acidemia are complex and lack of specificity. Newborn screening and high-risk screening are keys for early treatment and better outcome. The correlation between the genotype and phenotype of propionic acidemia is unclear, but certain variants may be associated with early-onset or late-onset propionic acidemia.

Abstract
Objective: To analyze the clinical features and CBS gene variants of 13 patients with classic homocystinuria, and the strategies of individual treatment and prevention were explored. Methods: The general information, clinical manifestations, laboratory tests, cranial images, CBS gene variants, diagnosis and therapeutic strategies of 13 patients with classic homocystinuria admitted to the Department of Pediatrics of Children's Hospital Affiliated to Zhengzhou University and Peking University First Hospital from November 2013 to June 2021 were analyzed retrospectively. Results: There were 13 patients diagnosed at the age of 10 days to 14 years, 6 were male and 7 were female. There were 3 patients detected by newborn screening and received treatment at the asymptomatic stage. There were 10 patients clinically diagnosed at the age of 5 to 14 years. Their symptoms appeared at age of 1 to 6 years. The major clinical manifestations were marfanoid features, lens dislocation and (or) myopia, developmental delay, osteoporosis, and cardiovascular diseases. Brain magnetic resonance imaging showed asymmetric infarcts in 4 patients and hypomyelination in 1 case. Increased blood methionine, plasma total homocysteine and urinary total homocysteine with normal urinary methylmalonic acid were found in 13 patients. The biochemical features were consistent with classic homocystinuria. Totally 18 variants were identified in CBS gene of 13 patients, 10 variants were novel and 8 were reported. only 1 patient was partially responsive to vitamin B6 treatment, while 12 cases were non-responsive. They were mainly treated with low methionine diet and betaine supplement. Three vitamin B6 non-responsive cases received liver transplantation at age of 3, 8 and 8 years, respectively. Their blood methionine and total homocysteine returned to normal within a week after liver transplantation. One patient died. Prenatal diagnosis was performed for a fetus when the mother was pregnant again. Two pathogenic CBS gene variants were identified from the amniocytes as same as the proband. Conclusions: The clinical manifestations of classic homocystinuria are complex and variable. Blood amino acid analysis, serum or urine total homocysteine assay and gene analysis are critical for its diagnosis. There were 10 novel CBS gene varients were identified expanding the CBS gene varient spectrum. Liver transplantation is an effective treatment. Prenatal diagnosis is important to prevent classic homocysteinuria.

Abstract
Health impact assessment (HIA) system has been listed in the Outline of the Healthy China 2030 Plan and the Law of Basic Health Care and Health Promotion of the People's Republic of China, however, the technique guideline of HIA needs to be established and improved. This paper summarizes the applications of different epidemiological methods in HIA and focus on the introduction of the application of ecology model of health social determinants as theory basis in the establishment of HIA system along with the introduction of HIA cases in the world. The applications of epidemiological methods in domestic HIA research are limited. Therefore, appropriate applications of epidemiological methods should be strengthened in HIA guideline and system development, especially the applications of big health data, mobile health techniques, systems epidemiology and implementation science, to facilitate data collection and potential health hazard evaluation and surveillance for HIA, establishment and improvement of HIA system and the implementation of Healthy China Strategy.

Abstract
Objective: To analyze the clinicopathological characteristics and intrahepatic immune cells infiltration condition after Kasai biliary atresia surgery. Methods: Data of 28 cases who underwent liver transplantation in the liver transplantation center of our hospital from June 2017 to March 2019 were enrolled. Of which, 20 cases were in the biliary atresia group (divided into two subgroups: 10 cases without Kasai surgery and 10 cases after Kasai surgery, and latter subsided cholestasis) and 8 cases in the control group. Clinical and pathological morphological characteristics of the groups were compared. Liver tissue sections were stained with immunohistochemistry and CD3, CD4, CD8, CD20, Foxp3, and interleukin-17A were quantitatively analyzed. Kruskal-Wallis test was used to measure the above indicators, and rank-sum test or Fisher's exact test was used to compare the count data. Results: The degree of clinical and pathological cholestasis in the biliary atresia group after Kasai surgery was significantly lower than that of the group without Kasai surgery, and the degree of liver fibrosis was also significantly reduced (P < 0.05), but there was no statistically significant difference in the degree of inflammation in the portal vein area between the two groups (P > 0.05). There was statistically significant difference in the types of immune cells infiltrated in the liver (P < 0.05). Compared with the group without Kasai surgery, the infiltration of CD3, CD8, IL-17A and Foxp3 positive cells in the portal vein area after Kasai surgery group (P < 0.05) was significantly reduced, but there was no statistically significant difference in the proportion of Foxp3/CD4 positive cells between the two groups (P > 0.05), which continued to be lower than that of the control group (P < 0.05). Compared with the non-Kasai surgery group, the proportion of Foxp3/IL-17A and Foxp3/CD8 positive cells in the portal vein area did not increase significantly after Kasai surgery group (P > 0.05), and remained lower than the control group. However, the proportion of Foxp3/IL-17A and Foxp3/CD8 positive cells was significantly reduced (P < 0.05). Conclusion: Intrahepatic inflammatory cell infiltration and regulatory/effector T lymphocyte proportion dysregulation exist in patients with subsided cholestasis after Kasai biliary atresia surgery, which may be an important factor to promote the disease progression.

Abstract
Objective: To summarize and compare clinicopathological features of Caroli disease and Caroli syndrome. Methods: A total of 21 patients diagnosed with Caroli disease or Caroli syndrome in Beijing Friendship Hospital, Capital Medical University, from January 2015 to December 2018 were included. Through the clinical manifestations and comparative analysis of the differences between different clinical types, the liver pathological features of these patients were described. Results: Of all patients included, 8 were male and 13 were female, and the medium age was 13.5 year old. The initial symptom was fever in 6 cases (28.6%), gastrointestinal bleeding in 6 cases (28.6%) and hepatosplenomegaly in 9 cases (42.8%). Caroli disease accounted for 6 cases (28.6%) and Caroli syndrome 15 cases (71.4%). The total bilirubin [6.7 (4.7, 15.0) vs 16.0(10.9, 33.0)μmol/L] and direct bilirubin [1.3(0.9,6.4)vs 3.5(2.7, 16.2)μmol/L] were significantly lower in Caroli disease group in comparison to those in Caroli syndrome group(both P<0.05). The hemoglobin [117.0 (106.0, 126.2) vs 85.0 (74.0, 103.0) g/L] and platelet count [286.0 (149.8, 467.5)×10(9)/L vs 76.1(55.0,123.0)×10(9)/L] in Caroli disease group were significantly higher than those in Caroli syndrome group (both P<0.05). There were 10 patients (47.6%) who underwent liver transplantation. Child-Pugh-Turcotte Score (liver function reserve) were significantly higher than that in the non-liver transplantation group[8.0(8.0, 10.2)vs 5.0 (5.0, 6.0), P<0.05]. Conclusions: Early symptoms of Caroli disease/Caroli syndrome are atypical and prone to misdiagnosis and misdiagnosis. The diagnosis is usually based on pathology and may be supplemented by laboratory examination and imaging analysis.

Abstract
Objective: To evaluate the effects of percutaneous nephrolithotomy (PNL) in the treatment of medullary sponge kidney with calculi. Methods: A total of 77 patients (91 renal units) of medullary sponge kidney with calculi (MSK group) and 77 patients (77 renal units) with common kidney stone (control group) received PNL at Department of Urology in Peking University People's Hospital from September 2006 to February 2016 were analyzed retrospectively. The MSK group included 33 males and 44 females with a mean age of (42.1±13.2) years, the mean stone burden was (3.9±1.8) cm. The control group included 36 males and 41 females with a mean age of (45.3±13.0) years, the mean stone burden was (3.6±1.5) cm. The numbers of tracts, the time of operation, the drop of hemoglobin, the change of creatine, the time of hospitalization, the stone free rate and major complications were compared between the two groups. The measurement data and numeration data were compared with t test and χ(2) test. Results: There were no significant differences in sex, age, preoperative urinary tract infection, stone type, and stone burden between the two groups (all P>0.05). The proportion of bilateral renal calculus in MSK group was higher (18.2% vs. 0, χ(2)=15.400, P=0.000). There were 159 percutaneous channels were established in MSK group while 90 percutaneous channels were established in control group. Compared with the control group, the operation time ((88.1±37.5) minutes vs. (68.5±30.1) minutes, t=3.543, P=0.000) and hospitalization time ((15.1±8.3) days vs. (10.1±3.6) days, t=4.816, P=0.000) were longer, the creatinine level increased ((101.2±62.6) μmol/L vs. (71.3±23.6) μmol/L, t=3.777, P=0.000), the rate of stone free decreased (27.5% vs. 83.1%, χ(2)=51.840, P=0.000) and the rate of complications increased (29.9% vs. 11.7%, χ(2)=8.114, P=0.004) in MSK group. There was no statistically difference in hemoglobin drop ((12.5±13.2) g/L vs. (13.0±10.9) g/L, t=-0.260, P=0.795). Conclusions: Using PNL for patients of MSK with calculi has a lower stone free rate and a higher complications. It is an effective method for patients of MSK with large and complex calculi.

Abstract
Objective:To study clinical features and evaluate the efficacy of manual reduction in treatment of atypical nystagmus in patients with posterior semicircular canal benign paroxysmal positional vertigo(PSC-BPPV). Method:Sixteen cases of atypical nystagmus in patients with PSC-BPPV were retrospectively analyzed. The results were compared with 28 patients of typical nystagmus with PSC-BPPV.All the patients were followed up for 3 months. Statistical data analysis was carried out with SPSS 20.0. Result:Sixteen cases of atypical nystagmus patients with PSC-BPPV included 5 cases of left 31.25%(5/16) and 11 cases of right 68.75%(11/16), 5 patients showed typical nystagmus in the straight-head hanging position and without vertical down-beating in returning to the sitting positions with torsional component pointed to intact side,4 patients showed same nystagmus in hanging position and vertical down-beating in returning to the sitting positions without torsional component, one patient showed nystagmus of vertical up-beating and vertical down-beating in Dix-Hallpike test without torsional component,2 patients showed unobservable nystagmus in Dix-Hallpike test but showed nystagmus of vertical up-beating with torsional component pointed to affected side in the roll test position,4 patients showed nystagmus of vertical down-beating in the straight-head hanging position with torsional component pointed to intact side and reversible direction nystagmus in returning to the sitting positions.One patient's nystagmus time of duration was longer than 1 min,while 15 patients' nystagmus duration were shorter than 1 min.Twenty-eight patients with typical nystagmus in PSC-BPPV nystagmus duration were shorter than 1 min.No patient had been affected bilateral in two groups. All patients received manual reduction treatment according to the nystagmus direction and time of duration. The effective rate after the first day was 62.50%(10/16) in atypical nystagmus patients with PSC-BPPV group and 92.86%(26/28) in typical nystagmus with PSC-BPPV group, the difference was significant(χ²=5.134,P=0.015). The total effective rate was 93.75%(15/16)after more than once in atypical group and 100.00%(28/28) in typical group, the difference was not significant(χ²=2.780,P=0.095).The numbers of circulation of first success in manual reduction management were(2.76±1.13)times in atypical group and (1.68±0.61)times in typical group.The difference was significant(t=4.293,P=0.000). The recurrence rate was 18.75% in atypical group and 14.28% in typical group after during follow-up for 6 months, the difference was not significant(χ²=1.681,P=0.509). Conclusion:It showed that clinical manifestation with atypical nystagmus in patients with PSC-BPPV was complicated. Some patients' nystagmus could change to typical after treatment.The manual reduction was an effective treatment.The effective rate after first manual reduction was lower than typical group, it's needed more circulation of first success in manual reduction management. The recurrence rate was not significant in two groups.

Abstract
A quadrichromatic light-emitting diode (QLED) based visible light communication for mobile phone camera is proposed to improve data rate and enhance illumination effect at the same time. Different from color intensity modulation (CIM), we propose and use color ratio modulation (CRM) in CMOS image sensor based visible light communication to improve data rate. According to the spectral power distribution (SPD) of the QLED and the spectral response of the complementary-metal-oxide-semiconductor (CMOS) image sensor, color multiple-input multiple-output (CMIMO) channel model is set up first to obtain optimal 16-CRM constellation design. Taking full consideration of the high quality of color rendering index (CRI), tunable color temperature (CT), we design a specific data packet structure to realize illumination requirements. A decoding strategy is also addressed for demapping at the receiver. The experimental results demonstrate that the proposed scheme can realize a downlink data rate of 13.2kbit/s, meanwhile, the optical signal source is illumination compatible.

Abstract
Objective: To evaluate the efficacy and safety of microsurgical crossover vasovasostomy in treating complicated obstructive azoospermia. Methods: The data of 14 patients with complicated obstructive azoospermia treated with microsurgical crossover vasovasostomy were reviewed from October 2012 to March 2016.Ten of them underwent microsurgical crossover vasovasostomy. Intraoperative exploration revealed that 2 patients had vas deferens injury and contralateral testicular atrophy or epididymal obstruction due to previous hernia repair; 7 patients had obstruction of intracorporeal vas deferens on one side and epididymal obstruction on the other side; the other 1 patient had unilateral vasal obstruction with contralateral epididymal obstruction. Furthermore, 4 patients underwent microsurgical crossover vasoepididymostomy, including 3 patients who had obstruction at caput epididymis on one side, and obstruction at cauda epididymis and distal vas deferens on the other side; the other patient had absence of vas deferens in the scrotum on one side, and testicular atrophy on the other side. Regular follow-up visits were conducted after the surgery. Results: Two patients were lost to follow-up; the other 12 patients were follow-up for an average of 11 (range: 2-23) months. In the 10 cases receiving microsurgical crossover vasovasostomy (including 2 patients lost to follow-up), 1 has not undergone semen re-analysis, 6 were confirmed patent, including 3 reporting spontaneous pregnancy. The patency rate in the 4 patients receiving microsurgical crosseover vasoepididymostomy was 2/4, with 1 patient reporting spontaneous pregnancy. There was no complaint of discomfort or complications following the surgery. Conclusions: Microsurgical crossover anastomosis may be effective and safe for patients with complicated obstructive azoospermia, according to preoperative assessment and intraoperative exploration. It allows natural conception for patients with refractory infertility. The microsurgical crossover anastomosis could be an effective therapy to achieve satisfactory patency of vas deferens.

Abstract
Objective: To investigate the clinical features and evaluate the efficacy of manual reduction in treatment of age patients with secondary benign paroxysmal positional vertigo (s-BPPV). Methods: Thirty-two cases of aged patients ( the s-BPPV group: including 19 cases of female and 13 males, age from 60 to 86 years old)with secondary benign paroxysmal positional vertigo from Jul. 2013 to Sep. 2015 in our hospital were retrospectively analyzed. The results were compared with 121 patients( the primary group: including 82 cases of female and 39males, aged from 60 to 86 years old)with aged primary benign paroxysmal positional vertigo(p -BPPV). All the patients were followed up for 12 months. Statistical data analysis was carried out with SPSS 19.0. Results: 20.92%(32/153)of all the observed elderly patients with BPPV was the aged s-BPPV. The sex ratio and onset age had no significant difference between the two groups(χ(2)=0.79, P>0.05; t=0.37, P>0.05). The rate of two or more semicircular canal involvement in the secondary group(21.88%) was higher than that in primary group(6.61%)(χ(2)=6.67, P<0.05). Bilateral semicircular canals were involved in 5 of the 32 cases in secondary group(15.63%) and 4 of the 121 cases in aged primary group(3.31%), The difference was significant(χ(2)=6.94, P<0.05). The effective rate after first manual reduction was 57.50%(23/40)in secondary group and 82.31%(107/130)in primary group, the difference was significant(χ(2)=10.46, P<0.05). The total effective rate were 87.50%(35/40) after more than once manual reduction in secondary group and 91.54%(119/130) in primary group, the difference was not significant(χ(2)= 0.59, P>0.05). The numbers of circulation of the first successful manual reduction management were (3.9±1.3)times in secondary group and (2.1±1.1)times in primary group, the difference was significant(t=3.15, P<0.05). The recurrence rate was 37.50%(15/40) in the secondary group and 16.15%(21/130)in primary group after during follow-up for 12 months, the difference was statistically significant(χ(2)=8.35, P<0.05). Conclusions: It's shown that the aged patients with secondary BPPV is not rare in clinical practice, sudden deafness and head trauma are frequent more than other reasons. The aged patients with secondary BPPV are prone to injury in multi-semicircular and bilateral canal compared with the primary BPPV. The effective rate after first manual reduction of secondary BPPV is lower than primary BPPV, it's needed more circulation of first success in manual reduction management. The total effective rates are not significant in two groups and recurrence rate is relatively high in secondary group.

Percentage of children with burn injury to total hospitalized patients with burn injury in the same period of time, age, causes of injury, gender, injury month, residence, condition of first aid measures conforming to medical standard, time of admission post injury, burn degree, and operation condition of children with burn injury were analyzed. Data were processed with Mann-Whitney U test and Chi-square test. Results: From January 2001 to December 2005 and January 2011 to December 2015, percentages of children with burn injury to total hospitalized patients with burn injury in the same period of time were respectively 23.6% (384/1 626) and 25.4% (596/2 346) , with no statistically significant difference (χ(2)=1.653, P>0.05). Age of all children with burn injury was 1.0 (1.0, 2.0) year old from January 2011 to December 2015, obviously lower than that from January 2001 to December 2005[1.0 (1.0, 3.0) year old, Z=-3.257, P<0.01]. Ages of children with burn caused by hot liquid and electrical burn from January 2011 to December 2015 were obviously lower than those from January 2001 to December 2005 (with Z values respectively -4.248 and -2.040, P<0.05 or P<0.01). Compared with that from January 2001 to December 2005, age of children with burn caused by flame from January 2011 to December 2015 increased, with no statistically significant difference (Z=1.852, P>0.05). There was no statistically significant difference in gender of children with burn injury between the two periods of time (χ(2)=1.374, P>0.05). Burn injury of children in the two periods of time mainly occurred in Spring, and season of burn injury between the two periods of time was similar (χ(2)=1.177, P>0.05). There was statistically significant difference in residence of children with burn injury between the two periods of time (χ(2)=15.513, P<0.01). The number of children with burn injury of first aid measures conforming to medical standard and admission within 6 h post injury from January 2011 to December 2015 was obviously more than that from January 2001 to December 2005 (with χ(2) values respectively 7.434 and 43.961, P values below 0.01). Burn degrees of children with burn injury mainly were moderate in the two periods of time, and there was no statistically significant difference in burn degree and condition of operation between the two periods of time (with χ(2) values respectively 5.731 and 1.583, P values above 0.05). Conclusions: Burn of children is a social problem. We should make great efforts on popularization of prevention and treatment about burn of children, especially children with younger age in rural areas. We should publicize standard first aid measures of burn of children and advocate admission of burn of children within 6 h post burn injury for treatment.

Abstract
Objective: To study the clinical characteristics, methods of diagnosis and treatment of hyperornithinemia-hyperammonemia- homocitrullinuria (HHH) syndrome. Method: From July 2011 to August 2016, 3 Chinese patients with HHH syndrome were enrolled in this study. The clinical course, biochemical features, brain MRI findings, and gene mutations were analyzed. Result: The three patients' age at onset of symptoms was 3 months to 7 years, and the age of diagonosis was 3 years and 10 months to 9 years and 10 months. All of them presented with intolerance to protein-rich foods from the infant period, development retardation and abnormal posture. Case 1 and 2 had moderate mental retardation. Serum ammonia 25-276 μmol/L (reference range<60 μmol/L), alanine aminotransferase (ALT) 20-139 IU/L (reference range 9-50 IU/L), ornithine 29.12-99.44 μmol/L(reference range 15-100 μmol/L), urinary orotic acid 1.49-29.75 mmol/mol Cr (reference range 0-7 mmol/mol Cr), uracil 6.09-103.97 mmol/mol Cr (reference range 0-1.5 mmol/mol Cr). The cranial MRI revealed lesions in the basal ganglia, abnormal white matter signal, progressive demyelination and cerebral atrophy. On their SLC25A15 gene, a novel homozygous missense mutation c. 416A>G (p.E139G) was identified in case 1, a known pathogenic homozygous nonsense mutation c. 535C>T was found in case 2 and 3. Liver transplantation had been performed when case 1 was 6 years old. Significant improvements were observed in dietary habit, mental and motor functions, and biochemical parameters. After the dietary intervention with the supplements of arginine, L-carnitine, case 2 was improved, spastic paraplegia of case 3 had no mitigation. Liver transplant was recommended. Conclusion: HHH syndrome has an aversion to protein-rich food, and the patients have recurrent vomiting and progressive neurological dysfunction. Clinical diagnosis of HHH syndrome is difficult and patients may present with incomplete biochemical phenotype. The genetic analysis is key for the diagnosis. Depending on their condition, individuals with HHH syndrome can be treated with a low-protein diet, drugs and liver transplantation.

Abstract
Pak choi is a highly nutritious vegetable that is widely grown in China, Southeast Asia, and other parts of the world. Because it reproduces by seed, it is very important to understand the mechanism of floral organ development. Therefore, using the Chinese cabbage genome as a reference, this study analyzed the expression profiles of shoot apex genes at flower bud differentiation stages 1 and 5, in order to identify genes related to floral organ development. The results showed that the proportion of mapped genes was high, with 84.25 and 83.80% of clean reads from the two sample saligned to the reference genome, respectively. A total of 525 differentially expressed genes (DEGs) were identified, 224 of which were upregulated and 301 were downregulated. The expression levels of genes homologous to Chinese cabbage flowering genes were also analyzed at stages 1 and 5; the expression levels of Bra012997 (ap1), Bra000393 (SOC1), and Bra004928 (SOC1) were significantly upregulated at stage 5, suggesting that these three genes positively regulate floral development in pak choi. DEGs involved in floral organ development were analyzed with homologous genes from Arabidopsis thaliana; the homologous genes Bra029281 (AGL42), Bra026577 (ARPN), Bra022954 (SPL3), Bra029293 (ARF2), Bra007978 (AtRLP12), Bra033221 (SPL8), Bra008037 (LOX4), Bra001598 (IAA19), Bra003892 (PATL1), Bra038778 (AT4G21323), Bra025315 (KLCR2), and Bra013906 (DTX35) are directly related to floral organ development in Arabidopsis, suggesting that these genes have corresponding functions during flower organ development in pak choi, and could be candidates for further genetic research. These results provide a foundation for research on the molecular mechanism of flower organ development in pak choi and other Brassica rapa vegetables.

Abstract
OBJECTIVE To evaluate the risk factors of systemic inflammatory response syndrome (SIRS) in the patients with type 2 diabetes diagnosed with kidney stone after percutaneous nephrolithotomy (PCNL). METHODS In this study, 461 patients with type 2 diabetes who received PCNL in Peking University People's Hospital from June 2006 to December 2015 were reviewed. There were 281 males and 180 females with an average age of 57 years were included, of whom, 137 were diagnosed with SIRS after PCNL. The demographic data, clinical features, and test results were compared between the patients with SIRS and without SIRS, trying to identify the correlation between their clinical characters and the occurrence of SIRS. RESULTS The SIRS was significantly correlated with the patients' preoperative white blood cell counting (×109/L) [7.76 (4.00-17.96) vs. 6.31 (2.00-17.40), P<0.001], preoperational blood glucose level (mmol/L) [7.30 (3.08-19.90) vs. 6.40 (3.42-16.78), P<0.001], operative time (min) [75 (20-270) vs. 60 (20-200), P<0.001], length of stay (d) [12 (2-46) vs. 11 (3-29), P=0.019], staghorn stones [38.8% (33/85) vs. 27.7% (104/376), P=0.042], and preoperational urinary tract infection [36.8% (50/136) vs. 26.6% (81/304), P=0.032]. There was no significant correlation between the SIRS and the patients' age, body mass index, preoperative hemoglobin level, preoperative serum creatinine, and transfusion. In multivariate analysis, abnormal preoperative white blood cell counting (OR=3.194, 95% CI: 1.531-6.666, P=0.002), operative time longer than 60 min (OR=1.635, 95% CI: 1.088-2.456, P=0.018), and preoperational blood glucose level higher than normal 7.1 mmol/L were significantly correlated with the presence of SIRS. CONCLUSION The high level of preoperational blood glucose, abnormal preoperative white blood cell counting, and long operative time were significantly correlated with the presence of SIRS in patients with type 2 diabetes after PCNL.

Abstract
OBJECTIVE We sought to review the etiopathogenesis, diagnosis, and surgical options for 253 patients with portal vein thrombosis (PVT) undergoing orthotopic liver transplantation (OLT) to assess the the impact of PVT on outcomes. METHODS We retrospectively analyzed the data from 2508 adult patients undergoing 2614 OLTs in our center from September 1998 to July 2007. PVT was scored according to the operative findings and Yerdel grading of PVT. No prisoners were used as donors for this study. RESULTS Two hundred fifty-three patients were diagnosed with PVT (10.09%): there were 104 grade I; 114, grade II; 29, grade III; and 6, grade IV PVT. Sex and previous splenectomy increased the risk for PVT. In grade I and II cases, we performed simple thrombectomy, eversion thrombectomy, or improved eversion thrombectomy (IET, innovated by our center), producing smooth postoperative recoveries with a 0% in-hospitality mortality. In grade III cases, 18 underwent successful IET. Of 11 subjects who had eversion thrombectomy, six failed, and the distal superior mesentery vein or dilated splanchnic collateral tributary had to be used as the inflow vessel in four patients, and portal vein arterialization were performed in the other two patients, all of whom experienced a smooth postoperative recovery except one who died of hepatic failure and pulmonary infection 2 weeks after the operation. The in-hospitality mortality was 3.45%. In grade IV cases, three underwent successful IET, but another three cases failed, with two of them requiring a renal vein as the inflow vessel, and other one undergoing portocaval hemitransposition, with one postoperative death due to hepatic failure and another of cancer recurrence, an in-hospitality mortality rate of 33.33%. The transfusion requirement among PVT patients was significantly higher than that in non-PVT patients (9.32 +/- 3.12 U vs 6.02 +/- 2.40 U; P < .01). Blood loss in PVT patients who underwent the IET technique was significantly lower than that for an eversion thrombectomy (2800.36 +/- 930.52 mL vs 5700.21 +/- 162.50 mL P < .05). The overall actuarial 1-year survival rate in PVT patients was similar to the controls (86.56% vs 89.40%; P > .05). CONCLUSION OLT was successfully performed for PVT patients. The grade of PVT decided the surgical strategy. Similar 1-year survival rates were attained between PVT patients and controls undergoing OLT.

Abstract
An HPLC method for the determination of brucine in seed dressing agents was investigated. The sample solution was separated on a Spherisorb C18 column(4.6 mm i.d. x 200 mm, 5 microns) with CH3OH-H2O-CTAB (88:12:0.04, m/m) as the mobile phase and detected at 254 nm. Calibration curve of brucine was obtained for the concentration range of 0.01 g/L-0.25 g/L. The linear regression equation was A = 11,485,814 rho + 21,229, r = 0.9997. The RSD was 1.2%(n = 11). The results show that this method is simple, specific and accurate.

Abstract
An epidemiologic study of penile cancer involving 141 cases and 150 community controls was undertaken in a high-risk area in China. Personal interviews, as well as physical examinations among the prospectively ascertained subjects, enabled evaluation of a variety of potential risk factors. Strongly related to risk were conditions restricting the motility of the foreskin, including phimosis or paraphimosis, particularly when so severe that circumcision was used for treatment. Poor hygiene practices also appeared to increase risk, particularly as evidenced by detection of smegma on physical examination, although it was difficult to decipher whether this association was etiologic or merely a consequence of disease. A sexual relationship outside of marriage was associated with a RR of 1.7, and appeared to be a more important discriminator than number of lifetime sexual partners. Risk was increased among subjects reporting previous genital conditions, particularly sexually transmitted diseases, and physical examinations revealed the appearance of genital warts among 13 cases vs. I control. Interviews with wives of study subjects failed to provide evidence of a "female factor" in the etiology of penile cancer. This study supports the need for further evaluation of the role of hygiene and sexually transmitted agents in the etiology of penile cancer.

Abstract
A model of irreversible hemorrhagic shock was reproduced in rats. Synchronous video tape recording with 2 cameras was used to observe the relationship between the change of blood pressure and that of microcirculation of rat cremaster muscle during shock. It was shown that after antishock treatment the degree of capillary perfusion is closely related with the survival rate and the restoration of pulse pressure is positively correlative with the percentage of open capillaries. The injection of crystal No 4 of Polygonum cuspidatum could restore the pulse pressure to a state above normal level. With the changing of pulse pressure, a pulsatile blood movement occurred in the opening of capillary which impacted and dislodged the plugging or stationary blood cells, leading to reperfusion of capillaries and increase of survival rate.

Abstract
From 1980 through 1985, 5 patients with primary tracheal carcinoma were admitted to Human Cancer Hospital, comprising 0.024% of total admissions during the same period. The incidence of lung cancer and laryngeal cancer was 386 and 43 times as high as that of tracheal carcinoma. All were proved pathologically. 3 patients were given radical operation, followed by radiotherapy; 1 received radiotherapy plus chemotherapy and the other, chemotherapy alone. All three patients treated by operation plus radiotherapy survived for more than 3 years and 2 of them are still alive. Diagnosis, causes and avoidance of misdiagnosis are discussed.
