This paper reports a woman diagnosed with citrullinemia type I (CTLNⅠ) in puerperium who was unfortunately died later. The 28-year-old patient (G1P1) delivered a live girl at 39 +2 gestational weeks and was transferred from a local hospital to Henan Provincial People's Hospital on January 11, 2020, due to "a 3-day paroxysmal confusion accompanied by dizziness 4 days after delivery". Intermittent confusion, elevated blood ammonia, and citrulline concentration, and encephaledema were presented 10 h after delivery, and the patient eventually died of cerebral hernia on the day of self-discharge. Two pathogenic mutations of the ASS1 gene were found by genetic testing, including c.422t>G (p.val141gl; HET) and c.431c>G (p.pro144arg; HET) and confirmed the diagnosis of CTLNⅠ. CTLNⅠ is a life-threatening disease that could be easily overlooked and misdiagnosed and was difficult to treat. It most often occurs in newborns and infants, whilst it is rare during pregnancy and postpartum. The possibility of this disease should be considered in patients with neurological system symptoms and elevated blood ammonia during pregnancy or puerperium.

The paper presented the theoretic basis for the comprehensive hospital evaluation system, and initiated the indicator system for hospital comprehensive evaluation results with both Delphi method and the balance scorecard. Two rounds of experts consultation have decided to evaluate hospital comprehensive strengths from such aspects as hospital resources deployment, business process, financial standing, customers, customers, public welfare and development potential of the hospital. Under these grade-1 indicators are 13 grade-2 ones and 83 grade-3 ones. The importance, operability and sensitivity of these indicators are accepted by experts unanimously.

BACKGROUND:In closed fractures, the initial hematoma that is inclined to remove is seldom considered as the important reasons for bone healing. OBJECTIVE:To observe the mechanism and potential role of original fracture hematoma in fracture healing. METHODS:Ninety-six patients with closed fractures of the long bones undergoing open reduction and internal fixation were randomly divided into experimental group (n=48) and control group (n=48). In the experimental group, original fracture hematoma, 1.0-2.0 mL, was first taken out during the internal fixation and placed into a special sterile plastic bag; then, 3-4 pieces of hematomas were filed into the fracture site and sutured layer by layer. On the contrary, original fracture hematomas from the control group were discarded. Blood samples were extracted to detect the biochemical indicators at 1 month after internal fixation. X-ray examination was done at 1, 3, 6 months after internal fixation for observation of fracture healing. RESULTS AND CONCLUSION: X-ray films showed that the healing rate at 3 months after operation was 95% in the experimental group and 78% in the control group, and there was a significant difference between the two groups (P < 0.05). Levels of bone glaprotein, I-type precolagen carboxy terminus peptide and serum bone alkaline phosphatase were significantly higher in the experimental group than the control group (P < 0.01 orP < 0.05). These findings indicate that the original fracture hematoma can accelerate calus formation, promote bone induction, provide nutrition to the fracture site, and participate in revascularization. Therefore, the original fracture hematomas is one of the effectively therapeutic methods for union and nonunion of fractures.

Objective To evaluate the effect of dexmedetomidine on renal functions during the anesthesia of renal transplantation.Methods Sixty patients (36 males, 24 females, aged 25-45 years, ASA physical status Ⅱ or Ⅲ), were randomly divided into two groups (n=30 each).Patients in dexmedetomidine group received a loading dose of dexmedetomidine 1 μg/kg within 10 min)and a continuous infusion of dexmedetomidine 0.6 μg·kg-1·h-1 until 30 min toward the end of surgery, while patients in control group received 0.9% sodium chloride injection to maintain equal capacity until 30 min before the end of surgery.Artery systolic blood pressure and heart rate were recorded before anesthesia induction (T1), before vascular anastomosis opening (T2), immediately after vascular anastomosis opening (T3), 30 min after vascular anastomosis opening (T4), after the surgery (T5), venous blood was collected in T2, T4, 24 h after surgery (T6) and 48 h after surgery (T7) to detect the blood urea nitrogen (BUN), serum creatinine (Cr), IL-18 and Cystatin C (Cys C);fluid infusion and urine were recorded.Results Compared with control group, HR of dexmedetomidine group was reduced at T3, SBP of dexmedetomidine group was elevated at T2, T3(P<0.05).Compared with T2, Cys C, BUN, Cr of two groups decreased significantly at T6, T7, and Cys C of dexmedetomidine group was lower than that of control group (P<0.05).Compared with T2, IL-18 of the two groups reduced significantly at T6 and T7, and lowered amplitude in the dexmedetomidine group was greater than that in the control group (P<0.05).Perioperative urine volume in the dexmedetomidine group was more than that in the control group (P<0.05).There was no difference in perioperative fluid infusion between the two groups.Conclusion Perioperative continuous infusion of dexmedetomidine might effectively improve the renal function of renal transplantation patients.

OBJECTIVE:To establish the method for simultaneous determination of 6 components in Lonicera japonica,and to study the content changes of them before and after before and after carbonized. METHODS:UPLC method was adopted. The deter-mination was performed on Agilent Eclipse Plus C18 RRHD column with mobile phase consisting of 0.1% phosphoric acid solu-tion-acetonitrile(gradient elution)at the flow rate of 0.2 mL /min. The detection wavelength was set at 350 nm,and column tem-perature was 25 ℃. The sample size was 1 μL. RESULTS:The linear ranges of chlorogenic acid,rutin,galuteolin,isochlorogenic acid A,isochlorogenic acid B and isochlorogenic acid C were 21.2-424 μg(r=0.9993),1.17-23 μg(r=0.9995),2.18-43 μg(r=0.9998),5.10-102 μg(r=0.9993),2.60-52 μg(r=0.9991),4.95-99 μg(r=0.9998),respectively. RSDs of precision,stability and repeatability tests were all lower than 2.0%. Recoveries were 97.11%-99.76%(RSD=1.20%,n=6),95.20%-99.90%(RSD=2.20%,n=6),95.71%-100.30%(RSD=2.20%,n=6),95.00%-96.98%(RSD=0.88%,n=6),96.47%-103.00%(RSD=2.40%, n=6),95.78%-103.80%(RSD=3.20%,n=6). Compared with before processing,the contents of rutin,isochlorogenic acid B and isochlorogenic acid C in L. japonica were increased along with processing,the contents of chlorogenic acid and isochlorogenic acid A were decreased significantly,while the content of galuteolin had no significant change. CONCLUSIONS:The method is sim-ple,precise,stable and repeatable,and can be used for simultaneous determination of 6 components in L. japonica. Those chemi-cal components have certain changes before and after carbonized.

Objective:To investigate the clinical efficacy and safety of modified Shaoyao Gancao decoction in the treatment of hyperprolactinemia caused by amisulpride. Methods:Ninety patients with hyperprolactinemia caused by amisulpride who received treatment in Kangci Hospital from June 2018 to October 2019 were included in this study. They were randomly divided into the placebo control, control and observation groups ( n = 30/group). The placebo control group was treated with the decoction with the taste and color (without drug ingredients) similar to that of modified Shaoyao Gancao decoction. The control group was treated with Shaoyao Gancao decoction. The observation group was treated with modified Shaoyao Gancao decoction. All patients were treated for 8 weeks. Clinical efficacy, serum prolactin level and Positive and Negative Syndrome Scale score before and after treatment, Treatment Emergent Symptom Scale score after treatment, glucose and lipid metabolism, liver and kidney function before and after treatment were compared among the three groups. Results:The effective rate in the placebo control, control and observation groups was 90.0% (27/30), 96.7% (29/30) and 100.0% (30/30), respectively, and the difference among the three groups was statistically significant (χ 2 = 7.027, P < 0.05). After treatment, serum prolactin level in the observation group [(48.2 ± 15.7) μg/L] was significantly lower than that in the control group [(52.5 ± 13.7) μg/L] and placebo control group [(57.7 ± 16.9) μg/L, t = 7.134, 7.034, both P < 0.05]. After treatment, Positive and Negative Syndrome Scale score in the observation group [(51.02 ± 3.98) points] was significantly lower than that in the control group [(54.07 ± 4.19) points] and placebo control group [(58.13 ± 4.24) points, t = 5.813, 6.317, both P < 0.05]. After treatment, Treatment Emergent Symptom Scale score in the observation group [(5.2 ± 1.3) points] was significantly higher than that in the control group [(4.9 ± 1.4) points] and placebo control group [(4.4 ± 1.2) points, t = 7.011, 7.231, both P < 0.05]. After treatment, blood glucose, low-density lipoprotein cholesterol, triglyceride, total cholesterol, alanine aminotransferase, aspartate aminotransferase levels in the observation group were significantly lower than those in the placebo control and control groups (all P < 0.05). Serum level of high-density lipoprotein cholesterol in the observation group was significantly higher than that in the placebo control and control groups (both P < 0.05). Conclusion:Modified Shaoyao Gancao decoction is highly effective in the treatment of hyperprolactinemia caused by amisulpride. It can reduce serum prolactin level and has good safety.

Objective:To compare the clinical efficacy of high frequency oscillatory ventilation (HFOV) and conventional mechanical ventilation (CMV) in the treatment of infants with severe respiratory syncytial virus (RSV) pneumonia.Methods:A prospective randomized controlled trial was conducted. The infants with severe RSV pneumonia who received invasive mechanical ventilation admitted to intensive care unit (ICU) of Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2018 to December 2019 were enrolled. According to the order of admission, each infant was assigned to HFOV group or CMV group by random number table. The basic data, pediatric critical score, blood gas analysis, ventilator parameters, oxygenation index [OI, OI = mean airway pressure (Pmean)×fraction of inspired oxygen (FiO 2)/arterial partial pressure of oxygen (PaO 2)×100], duration of mechanical ventilation, length of ICU stay, complications, prognosis, use of muscle relaxants and vasoactive drugs and other clinical indicators of the two groups were recorded. Results:A total of 28 infants were enrolled in the analysis, including 15 infants receiving CMV and 13 infants receiving HFOV. There were no significant differences in age, body weight, pediatric critical score and OI before enrollment, type Ⅱ respiratory failure, multiple organ dysfunction, basic diseases and laboratory examination indexes before enrollment between the two groups. Six hours after enrollment, compared with CMV group, heart rate (HR), respiratory rate (RR), case of transcutaneous oxygen saturation (SpO 2) decrease, case of HR decrease, case of cardiopulmonary resuscitation (CPR) and OI in HFOV group were significantly decreased [HR (bpm): 130 (125, 138) vs. 144 (140, 160), RR (times/min): 35 (34, 38) vs. 40 (35, 45), SpO 2 decrease (case: 1 vs. 10), HR decrease (case: 0 vs. 6), CPR (case: 0 vs. 4), OI: 6.5 (4.4, 8.9) vs. 9.3 (8.0, 12.8)], while case of use of muscle relaxants (case: 3 vs. 0) and volume of 7-day positive fluid balance [mL/kg: 167.1 (113.8, 212.6) vs. 90.8 (57.8, 112.7)] were significantly higher, the differences were statistically significant (all P < 0.05). There was no use of blood purification treatment, no severe complications such as pneumothorax and intracranial hemorrhage, and no death within 28 days in the two groups. Conclusion:Compared with CMV, HFOV in the treatment of infants with severe RSV pneumonia can improve the oxygenation level and clinical physiological indexes earlier, reduce the incidence of adverse events such as HR, SpO 2 decrease and CPR, increase the use of muscle relaxants and the positive fluid balance, and do not increase the incidence of severe complications such as pneumothorax and intracranial hemorrhage, so its clinical application is safe.

Objective To describe the distributions of FCGR polymorphisms in human immunodeficiency virus (HIV)-uninfected patients with cryptococcosis,and to investigate the association of FCGR polymorphisms with the susceptibility to cryptococcosis.Methods The distributions of the four functional polymorphisms,including FCGR2A 131H/R,FCGR3A 158F/V,FCGR3B NA1/NA2,and FCGR2B 232I/T were compared between 198 cryptococcosis patients and 190 healthy controls.The polymorphisms distribution patterns were also compared between patients with central nervous system (CNS) infection and those without CNS infection.Genotyping of eight single nucleotide polymorphism (SNP) in FCGR were performed by multiplex SNaPshot technology using DNA extracted from blood samples.The comparison between patients and controls was performed by chi square test or Fisher exact test.Results Compared to healthy controls,the frequency of FCGR2B 232I/I increased (65％ vs 53％,x2 =4.27,P=0.039,OR=1.652,95％CI:1.02-2.67) and that of FCGR2B 232I/T decreased (27％ vs 40％,x2 =5.77,P=0.016.OR=0.542,95％CI:0.33-0.90) in patients with cryptococcal meningitis.Among immunocompetent patients,the frequency of FCGR2B 232I/I was also over-presented (69％ vs 53％,x2=4.53,P =0.033,OR=1.958,95％CI:1.05-3.66) and the FCGR2B 232I/T genotype was also less frequently observed (24％ vs 40％,x2=5.14,P=0.023,OR=0.467,95％CI:0.24-0.91) compared to healthy controls.There were 117 cases with CNS infection and 81 non-CNS infection cases.The genotype of FCGR2A 131R/Rwas over-presented (19％ vs 6％,x2 =6.48,P=0.011,OR=3.52,95％CI:1.27-9.73) and the FCGR2B 232I/T genotype was under-presented (27 ％ vs 46 ％,x2 =7.56,P =0.006,OR=0.431,95％CI:0.24-0.79) in patients with CNS infection compared with those without CNS infection.Furthermore,the frequency of FCGR2B 232I/I genotypes increased (69％ vs47％,x2 =5.47,P=0.019,OR=2.479,95％CI:1.15-5.34) and the frequency of FCGR2B 232I/T decreased (24％ vs 51％,x2 =8.66,P=0.003,OR=0.307,95％CI:0.14-0.68) in immunocompetent patients with CNS infection compared with those without CNS infection.Conclusions FCGR2A 131H/R and FCGR2B 232I/T are associated with the susceptibility to cryptococcal CNS infection,which suggests that FcγRⅡA and FcγRⅡB may contribute to the pathogenesis of cryptococcosis.
