Objective:To investigate the efficacy and safety of hyperthermic intraperitoneal chemotherapy combined with immune checkpoint inhibitors in treatment of gastric cancer with ascites.Methods:A retrospective case-control study was conducted. The clinical data of 39 gastric cancer patients with malignant ascites treated in Xi'an Third Hospital from May 2021 to June 2023 were retrospectively analyzed. All patients were divided into the routine group (18 cases) and the observation group (21 cases) according to different treatment methods. The patients in the routine group were treated with hyperthermic intraperitoneal chemotherapy combined with systemic intravenous chemotherapy; the patients in the observation group were treated with immune checkpoint inhibitors on the basis of hyperthermic intraperitoneal chemotherapy combined with systemic intravenous chemotherapy. The clinical efficacy, tumor marker levels, Karnofsky scores, and incidence of adverse reactions of both groups were compared. Kaplan-Meier method was used to analyze the overall survival (OS) of both groups.Results:There were 12 males (66.7%) and 6 females (33.3%) in the routine group, with the age of (57±13) years; 13 males (61.9%) and 8 females (38.1%) in the observation group, with the age of (59±12) years. After treatment, the serum carcinoembryonic antigen (CEA), carbohydrate 125 (CA125), carbohydrate 199 (CA199) levels in the 2 groups were lower than those before treatment, and the differences were statistically significant (all P < 0.05). After treatment, the serum CEA, CA125, CA199 levels in the observation group were lower than those in the routine group, and the differences were statistically significant (all P < 0.05). After treatment, Karnofsky scores in the observation group were higher than those before treatment [(78.6±7.5) scores vs. (69.5±8.9) scores], and Karnofsky scores in the observation group were higher than those in the routine group [(78.6±7.5) scores vs. (72.8±7.9) scores],and the differences were statistically significant ( t = -3.65, 2.33, all P < 0.05). The objective remission rate (ORR) was 55.6% (10/18) and 71.4%(15/21), respectively in the routine group and the observation group, and the difference was statistically significant ( χ2 = 9.24, P = 0.002). The median OS time was 38.97 months (95% CI: 34.99-42.95 months) and 23.62 months (95% CI: 18.49-28.74 months), respectively in the observation group and the routine group, and the difference was statistically significant ( χ2 = 3.88, P = 0.049). There was no statistically significant difference in the incidence of adverse events between the 2 groups (all P > 0.05). No serious treatment-related complications were found in the observation group. Conclusions:Hyperthermic intraperitoneal chemotherapy combined with immune checkpoint inhibitors shows a good therapeutic effect in the treatment of gastric cancer with ascites, and the adverse reactions are controllable.

Objective: To investigate the incidence and constituent ratio of odontogenic tumors or odontogenic cysts in School and Hospital of Stomatology, Jilin University and to provide the reference for the clinical treatment. Methods: According to the WHO 2017 histological classification criteria, the pathological data of 4181 patients diagnosed as odontogenic tumors or odontogenic cysts in the Department of Pathology, Jilin University Stomatological Hospital from January 1961 to December 2017 were collected. Statistical analysis of the pathological types, gender, age and location of various tumors and cysts was conducted. Results: Of 4 181 cases, 1 055 were tumors and 3 126 were cysts. Among odontogenic tumors, benign tumors accounted for 96.11% (1 014/1 055), and malignant tumors accounted for 3.89% (41/1 055). The most common pathological type of odontogenic tumors was ameloblastoma [53.27% (562/1 055)], followed by cemento-ossifying fibroma [21.23% (224/1 055)] and odontoma [12.99% (137/1 055)]. The male-female ratio was 1∶1.04. The high-risk ages were 10-39. Maxilla-mandible ratio was 1∶2.85.As for cysts, radicular cysts [50.45% (1 577/3 126)] was the most common pathological type, followed by odontogenic keratocyst [25.59% (800/3 126)] and dentigerous cysts [21.56% (674/3 126)]. The male-female ratio was 1.37∶1. The high-risk ages were 20-49. Maxilla-mandible ratio was 1.37∶1. Conclusions There was no gender preference for odontogenic tumors in Jilin Province area in the 57 years. The majority tumors occurred in the radicular. The most common pathological type was ameloblastoma. As for odontogenic cysts, males showed a higher incidence and the majority cysts occurred in the maxilla. The most common pathological type was radicular cysts.

Objective: To analyz the current situation of the diagnosis, treatment and prevention of methylmalonic acidemia, the phenotypes, biochemical features and genotypes of the patients in the mainland of China, were investigated. Methods: Tottally 1 003 patients of methylmalonic acidemia from 26 provinces and municipalities of the mainland of China were enrolled. The clinical data, biochemical features and gene mutations were studied. Blood aminoacids and acylcarnitines, urine organic acids, and plasma total homocysteine were determined for the biochemical diagnosis. Gene analyses were performed for the genetic study of 661 patients. The patients were treated with individual intervention and long-term follow up. Prenatal diagnoses were carried out for 165 fetuses of the families. Results: Among 1 003 patients (580 boys and 423 girls), 296 cases (29.5%) had isolated methylmalonic acidemia; 707 cases (70.5%) had combined homocysteinemia; 59 patients (5.9%) were detected by newborn screening; 944 patients (94.1%) had the onset at the ages from several minutes after birth to 25 years and diagnosed at 3 days to 25 years of age. The main clinical presentations were psychomotor retardation and metabolic crisis. Multi-organ damage, including hematological abnormalities, pulmonary hypertension, kidney damage, were found. MMACHC, MUT, MMAA, MMAB, HCFC1, SUCLG1, SUCLA2 mutations were found in 631 patients (96.6%) out of 661 patients who accepted gene analysis. MMACHC mutations were detected in 460 patients (94.7%) out of 486 cases of methylmalonic acidemia combined with homocysteinemia. MUT mutations were found in 158 (90.3%) out of 169 cases of isolated methylmalonic acidemia. The development of 59 patients detected by newborn screening were normal; 918 cases (97.2%) were diagnosed after onset accepted the treatment. Forty-five of them completely recovered with normal development. Twenty-six patients (2.7%) died; 873 (92.5%) patients had mild to severe psychomotor retardation. Methylmalonic acidemia were found in 35 out of 165 fetuses by metabolites assay of amniotic fluid and amniocytes gene analysis. Conclusion Combined methylmalonic acidemia and homocysteinemia is the common type of methylmalonic acidemia in the mainland of China. CblC defect due to MMACHC mutations is the most common type of methylmalonic acidemia combined with homocysteinemia. MUT gene mutations are frequent in the patients with isolated methylmalonic acidemia. Newborn screening is key for the early diagnosis and the better outcome. Combined diagnosis of biochemical assays and gene analysis are reliable for the prenatal diagnosis of methylmalonic acidemia.

Objective·To study the hemodynamic parameters of uterine at midluteal phase in patients with early recurrent spontaneous abortion (ERSA) and the effect of aspirin on them. Methods·Transvaginal color Doppler ultrasonography was used to measure the parameters of uterine blood flow and the endometrial thickness at midluteal phase of 271 women with ERSA (ERSA group) and 66 women without a history of recurrent spontaneous abortion (control group). Then ERSA group were administered with aspirin 50 mg/d orally for 2 months and other individualized treatment, and the effect of aspirin on parameters of uterine blood flow and the early pregnancy outcome of them were observed. Results·At midluteal phase, the endometrium was significantly thinner in ERSA group than that in control group. Pulsatility index (PI) of endometrial blood flow and mean PI (mPI), mean resistance index (mRI), and mean systolic/diastolic ratio value (mS/D) of uterine arteries were statistically significantly higher in ERSA group in comparison to control group (P<0.05). Following aspirin treatment, resistance to uterine blood flow reduced significantly in ERSA group (P=0.000), and the endometrial thickness increased in the patients with endometrial thickness less than 7 mm (P=0.000). Only 163 ERSA patients were re-examined by transvaginal color Doppler ultrasonography after aspirin treatment, among whom 136 women was pregnant after individualized treatment. Among these pregnant patients, 97 cases were pregnant for more than or equal to 12 weeks, while 10 cases aborted during the first 12 weeks, and the early pregnancy outcomes of the other 29 cases were still unclear. Conclusion·In comparison with normal fertile women, ERSA patients have significantly higher resistance to uterine blood flow and thinner endometrium. Aspirin can improve uterine blood perfusion, which improves early pregnancy outcome.

Objective · To investigate the status of depression and anxiety in patients with recurrent spontaneous abortion (RSA) and the possible influence factors and to provide theoretical support for further psychological intervention. Methods · RSA patients and women with no history of RSA were invited to complete a questionnaire, including basic information, Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS). All data were analyzed by SPSS. Results · Of all 1064 cases included in this study, 725 were RSA cases, 217 cases with one spontaneous abortion and 122 in control group with no history of spontaneous abortion. Our results showed that both RSA patients and patients with one spontaneous abortion have significantly higher SDS and SAS scores than control group. Furthermore, non-pregnant RSA patients with lower education level, lower household income and 3-5 years of marriage have significantly higher levels of depression and anxiety. Patients with multiple miscarriages (≥4), history of induced abortion and no live birth, score significantly higher in SDS. Conclusion · Whether pregnant or not, RSA patients are much easier to become depressive and anxious, which may be associated with education level, household income, length of marriage, numbers of pregnancy losses and previous live birth. Women with one spontaneous abortion also show a significant higher tendency of depression and anxiety. These patients should be given proper psychological intervention if necessary.

OBJECTIVEWe report the first case of acute encephalopathy induced by vaccination in an infant with methylmalonic aciduria cblA in China.

METHODThe clinical presentation, blood acylcarnitines analysis, urine organic acids analysis and gene studies of the patient were summarized.

RESULTThe proband, a boy, was admitted at the age of 15 months because of recurrent vomiting, acidosis and development delay for 8 months. The previously healthy boy presented vomiting and coma just one hour after hepatitis B vaccination at the age of seven months. Moderate dehydration, electrolyte disturbance and metabolic acidosis had been found. Although his acute metabolic crisis had been corrected soon after intravenous transfusion, psychomotor retardation and recurrent vomiting had been observed. When he was 15 months old, vomiting and lethargy occurred again 3 hours after DTaP vaccination. He was weakened as the illness became worse and got coma with dyspnea 7 days later. He was hospitalized with the suspected diagnosis of viral encephalitis. Blood acylcarnitines analysis, urine organic acids analysis and gene study had been performed for the etiologic investigation.His blood propionylcarnitine (16.3 µmol/L vs. normal range 1.0-5.0 µmol/L) and propionylcarnitine/free carnitine ratio (0.27 vs. normal range 0.03 to 0.25) increased. Markedly elevated urinary methylmalonic acid (388.21 mmol/mol creatinine vs. normal range 0.2 to 3.6 mmol/mol creatinine) and normal plasma total homocysteine supported the diagnosis of isolated methylmalonic aciduria. Two mutations, c.650 T>A (p.L217X) and c.742 C>T (p.Q248X), were identified in his MMAA gene, confirmed the diagnosis of cblA. Each parent carried one of the two mutations. Progressive clinical and biochemical improvement has been observed after hydroxylcobalamin injection, protein-restricted diet with the supplements of special formula and L-carnitine. He is currently 2 years and 7 months old with normal development and general condition.

CONCLUSIONA boy with cblA was firstly detected after the acute encephalopathy induced by vaccination in China. It is important to pay more attention to the patients with metabolic crisis or organ damage after vaccination. Metabolic studies are keys to the diagnosis of potential diseases and improve the outcome.

OBJECTIVEArgininemia is a rare disorder of urea cycle defect. The clinical manifestations of this disorder are similar to those of cerebral palsy so that the diagnosis is usually much delayed. This study aimed to investigate the phenotypes and genotypes of seven Chinese patients suffering from argininemia.

METHODThree boys and four girls with spastic tetraplegia were diagnosed as argininemia by blood aminoacids analysis and ARG1 gene study. Patients were given a protein-restricted diet, citrulline, sodium benzoate, and other treatment intervention. The mother of Patient 5 and 6 accepted genetic counseling and underwent prenatal diagnosis by amniocentesis.

RESULTSeven patients presented with progressive spastic tetraplegia and poor physical growth from the age of 1 month to 4 years. Argininemia was found at the age of 1 year and 10 months to 12 years. Five patients had mental retardations. Three had seizures. Their blood arginine elevated (86.66 to 349.83 µmol/L, normal controls 5 to 25 µmol/L). Liver dysfunction was found in six patients. Five patients had elevated blood ammonia levels. In four patients, cerebral atrophy was observed by cranial magnetic resonance imaging. Nine mutations in the ARG1 gene were identified from 7 patients. Only two mutations, c.703G > A in exon 7 and c.32T > C in exon 1 had been reported. c.34G > T, c.53G > A, c.67delG, c.232dupG, c.374C > T, c.539G > C and c.646-649delCTCA, were novel mutations of ARG1. A homozygous mutation c.703G > A was found in the amniocytes of Patient 5's mother, indicating that the fetus was affected by argininemia. Induced abortion was performed. c.53G > A from Patient 6 was not found in the amniocytes of her mother, indicating that the fetus was not affected by hepatocyte arginase deficiency. The result was confirmed by postnatal mutation analysis of cord blood and the normal blood arginine of the newborn.

CONCLUSIONArgininemia is one of the few treatable causes of pediatric spastic paralysis. In this study, seven Chinese patients with spastic tetraplegia were detected by blood aminoacids analysis and confirmed by molecular analysis. Seven novel mutations on ARG1 gene were identified. Prenatal diagnosis of the fetus of a family was performed by amniocytes ARG1 gene analysis.

Objective To investigate the clinical,biochemical and genetic findings in patients with isolated methylmalonic aciduria. Methods From January 2001 to December 2014,a total of 126 patients with isolated methyl-malonic aciduria from Peking University First Hospital were enrolled in this study. In 60 patients,gene analysis was per-formed. The clinical characteristics,laboratory findings,treatment and outcomes were retrospectively analyzed. Results Among the 126 patients,only 3 cases(2. 4% )were detected through newborn screening and treated with dietary in-tervention,cobalamin and L - camitine. The age at onset of 123 cases(97. 6% )varied from a few hours after birth to 7 years and 11 months old. The common presentations were recurrent vomiting,mental retardation,poor feeding,lethargy, respiratory distress,coma,seizures,cutaneous lesion and jaundice with 11 patients(8. 73% )dead. Abnormal family his-tory was found in 27(21. 4% )patients. Metabolic acidosis and anemia were frequent laboratory findings. Basal ganglia damage and white matter changes were observed in most patients. Sixty patients got genetic analysis,and 58 cases of them had MUT gene mutations. One case had MMAA defect. One case had MMAB defect. In MUT gene,12 novel muta-tions were identified. After treatment,mild to severe psychomotor retardation was observed in 112 patients with isolated methylmalonic aciduria. Conclusions The clinical manifestation of patients with isolated methylmalonic aciduria is complex,and prone to appear metabolic crisis. MUT defect is the main cause. Early metabolic investigation is very im-portant to reach diagnosis. Newborn screening,early diagnosis and adequate therapy are key points to reduce the morta-lity and handicap.

OBJECTIVETo investigate the clinical, biochemical and genetic profiles of 28 Chinese patients with glutaric aciduria type 1.

METHODTwenty-eight patients with glutaric aciduria type 1 seen in the Department of Pediatrics, Peking University First Hospital from July 2003 to October 2013 were studied. The data of clinical course, laboratory examinations, cranial MRI and GCDH gene mutations of the patients were analyzed.

RESULT(1) Three cases were detected by newborn screening, and the other patients were diagnosed at the age of 2 months to 17 years. (2) 22 patients (79%) were infant onset cases with psychomotor retardation, dystonia, seizures, athetosis, recurrent vomiting, drowsiness or feeding difficulty. Only two of the 22 patients with infant onset got normal intelligence and movement after treatment. Twenty of them were improved slowly with delayed development, dystonia and other neurological problems. Three patients (11%) had late onset. They had motor regression, headache and seizure at the age of 8, 9 and 17 years, respectively. Rapid improvement was observed after treatment. (3) Cranial MRI has been checked in 23 patients; 22 of them showed characteristic widening of the Sylvian fissure, abnormalities of the basal ganglia, leukoencephalopathy and brain atrophy. Thirty-five mutations in GCDH gene of the patients were identified; c.148T>C (p.W50R) was the most common mutation with the frequency of 7.7%; 6 mutations (c.628A>G, c.700C>T, c.731G>T, c.963G>C, c.1031C>T and c.1109T>C) were novel.

CONCLUSIONGlutaric aciduria type 1 usually induced neurological deterioration resulting in severe psychomotor retardation and dystonia. Most of our patients were clinically diagnosed. Patients with early onset usually remained having neurological damage. Phenotype and genotype correlation has not been found in the patients. Neonatal screening for organic acidurias should be expanded in China.
