Objective: To compare the molecular weight of sodium hyaluronate in the injection determined by three methods. Methods:Viscometry was used to determine the molecular weight of sodium hyaluronate. The molecular weight and its distribution ( Mw/Mn) was measured by size exclusion chromatography ( SEC) and the combination of multi-angle laser light scattering instrument and size exclusion chromatography( MALLS-SEC) . Results:The results of MALLS-SEC were close to those of viscometry, and Mw/Mn was obtained simultaneously. The average value of molecular weight of three batches of samples was 991962, 1007438 and 990232 with RSD of 6. 5%, 4. 6% and 2. 2%, respectively(n=4). The average value of Mw/Mn was 1. 6, 1. 6 and 1. 6 with RSD of 7. 2%, 3. 2% and 3. 2%, respectively(n=4). Conclusion:MALLS-SEC shows better accuracy and precision, and can be used in the quali-ty control of sodium hyaluronate samples.

Objective Cystic nephroma ( CN ) is an unusual benign neoplasm with high misdiagnosis rate , and at present there is no general method on its treatment .This study aimed to analyze the diagnosis and treatment of CN based on clinical data of CN patients. Methods We retrospectively analyzed the clinical data on 25 patients (including 2 cases of male pediatric patients , aged 14 and 16 years old, and the remaining 23 cases were adults, 11 males and 12 females, aged 14-69[45.1 ±19.6]years) treated in our department of the First Hospital of Shijiazhuang from January 2003 to July 2015 .All patients underwent ultrasound , CT and MRI examination , as well as surgical resection . Results Among these 25 CN patients , there were 15 cases of partial nephrectomy , 5 ca-ses of nephrectomy , 2 cases of retroperitoneal laparoscopic cyst unroofing , 1 case of laparoscopic enucleation of the tumors with nephron-sparing surgery , 1 case of laparoscopic radical nephroureterectomy , and 1 case of retroperitoneal laparoscopic radical nephrectomy .All the patients were successfully followed up for 6 months to 132 months, 1 patient recurred 6 months after retroperitoneal laparoscopic cyst unroo-fing and underwent open partial nephrectomy .No recurrence and me-tastasis were found in the remaining patients . Conclusion Imaging examination is an important measurement for CN , and intraoperative frozen pathology contributes to pathological diagnosis .Since most CN cases are benign , CN patients with no symptom or small cysts can take follow up survey .The principle of the operation is complete resection of the tumor , and nephron-sparing surgery is the first choice . In addition , regular follow-up is necessary in case of recurrence and malignant potential .

ObjectiveTo investigate the features of normal and psoriasis skin on ultrasound biomicroscopy (UBM) and explore the method of thickness measurement.MethodsUsing 50 MHz ultrasound probe of biological microscope, ultrasonographic observation and ultrasonic thickness measurement were conducted in 90 normal adults and 40 psoriasis patients. Innormal patients, ultrasound evaluations were performed at 10 different parts of the body skin.ResultsOn sonogram, the normal skin showed a “sandwich” structure with two parallel hyperechoic bands and the middle isoechoic dots and short liens. The sonograms of the psoriasis skin showed obviously thickened epidermis and dermis, disordered internal structure and clear boundary from adjacent normal skin. The range of the epidermis’ thickness measurement was between the medial forearm (0.12±0.03) mm and the palm (0.29±0.15) mm. The range of dermal thickness measurement was between the back hand (1.18±0.32) mm and parasternal (1.55±0.21) mm. Psoriasis skin was thicker than the uninvolved skin (P<0.001). And the dermis’ thickness of uninvolved skin in psoriasis patients was thicker than that of the normal adults (P<0.001).ConclusionNormal adult’s epidermis, dermis and skin appendages can be shown clearly using 50 MHz ultrasound biomicroscopy. And ultrasound biomicroscopy canaccurately measure the thickness of dermis and epidermis, which provides the basis for the diagnosis and treatment of psoriasis.

Objective To analyze the social and family factors influencing rehabilitation of mental retarded children.Methods 237 children diagnosed as mental retardation in 2004 in Beijing were researched with Self-designed Questionnaires and data were analyzed by Cross-tabs and Logistic Regression statistical method.Results The analysis showed that the degree of disabilities (P<0.001), education received (P<0.05), and the attitude from community to these children (P<0.05), were factors influencing rehabilitation of mental retarded children.Conclusion The degree of disabilities is the most important influencing factor to rehabilitation of mental retarded children; the mild or moderate mental cases can get good rehabilitation in a better community and family environment. The attitude to these children from community can make a great help to the rehabilitation.

We report two cases of Joubert syndrome initially tentatively diagnosed by prenatal ultrasound in the first or second trimester which were thereafter confirmed by whole exome sequencing (WES). Case 1 was one of the twins who presented with increased intracranial transparency (IT) and thinner brainstem at 12 +1 gestational weeks. Ultrasound at 18 +2 weeks found multiple intracranial malformations, "molar tooth sign (MTS)" at the midbrain-hindbrain junction level in the cerebral cross section, and bilateral ventriculomegaly. Enlarged and echogenic kidneys and oligohydramnios were also detected. In case 2, ultrasound image at 17 +5 weeks of gestation indicated multiple intra-and extra cranial and extracranial malformations, MTS in the midbrain-hindbrain junction plane, bilateral ventriculomegaly, unclear cavum septum pellucidum. Extracranial anomalies were bilateral multicystic enlarged kidneys, invisible bladder, and oligohydramnios. Both fetuses underwent amniocentesis, which showed normal karyotype and no copy number variation was detected. However, variation of the TMEM67 gene (c.312+5G>A at introns 2 and c.1175C>G at exon12) was detected in both fetuses by WES, supporting the diagnosis of Joubert syndrome. Selective reduction and termination of pregnancy were performed on case 1 and case 2 at 18 +5 and 19 weeks of gestation, respectively.

Objective:To explore the diagnostic value of ultrasound in posterior fossa anomalies (PFA) at 11-13 + 6 gestational weeks by measuring brainstem (BS), brainstem-to-occipital bone (BSOB) diameter and BS/BSOB ratio. Methods:A total of 209 normal fetuses (control group) were randomly selected from Beijing Obstetrics and Gynecology Hospital, Capital Medical University, between March 2018 and November 2021. Reference ranges for BS, BSOB diameter and BS/BSOB ratio were obtained on the mid-sagittal view of the fetal profile and the relationship of three parameters and crown-rump length (CRL) was investigated. The intra- and inter-observer reliabilities were determined by intraclass correlation coefficient (ICC) in 30 normal fetuses. Fourteen fetuses diagnosed with PFA in the same period including 10 cases of cystic posterior fossa malformations (cPFM) and 4 cases of open spine bifida (OSB) were retrospectively selected to compare BS, BSOB diameter and the BS/BSOB ratio with control group.Results:BS and BSOB diameters were successfully obtained in all control fetuses (100%), and the intra- and inter-observer reliabilities for BS and BSOB diameters were good (ICC=0.877, 0.846 and 0.939, 0.895). In the control group, BS and BSOB diameter linearly correlated with CRL ( r=0.867, 0.794; all P<0.001), while the BS/BSOB ratio was 0.75 (0.71, 0.79). There were significant differences of BSOB diameter and BS/BSOB ratio between control group and PFA group (all P<0.05). Except for one isolated vermian hypoplasia (VH), the BSOB diameters in 9 (90%) cases of cPFM were above the 95th percentile of the calculated normal range and were below the 5th percentile in 4(100%) cases of OSB.Except for one isolated VH, the BS/BSOB ratio in 9 (90%) cases of cPFM was below the 5th percentile of the calculated normal range. The BS/BSOB ratio in 4 (100%) cases of OSB was above the 95th percentile of the calculated normal range. Conclusions:The measurements of BS and BSOB diameter are feasible with good repeatability. Abnormal BSOB diameter and BS/BSOB ratio are suggestive for PFA. The posterior fossa of isolated VH can be normal in the first trimester.

OBJECTIVETo evaluate the effect of individualized scalp acupuncture base on location of brain function for motor dysfunction in stroke patients.

METHODSA total of 180 patients were randomly assigned into an individualized scalp acupuncture (ISA) group, a conventional scalp acupuncture (CSA) group and a rehabilitation group, 60 cases in each one. In the ISA group, we stimulated Sishencong (EX-HN 1), motor area and balance area, matched with pre-motor area for higher muscle tension, application area and's three-needle for involuntary motion, application area for poor motor coordination, forehead five-needle for cognitive disorder, sensory area for sensory disturbance. In the CSA group, the affected Dingnieqianxiexian (MS 6), Dingniehouxiexian (MS 7) and Zhenxiapangxian (MS 14) were selected. Rehabilitation was used during needle retained in the two groups. Simple rehabilitation was used in the rehabilitation group. All the treatment was given from Monday to Friday for 4 weeks, once a day for 20 times. Eight-week follow-up was applied. The Fugl-Meyer assessment (FMA) for motor function, modified Barthel Index (MBI) were used to evaluate clinical effect.

RESULTSAfter treatment and at follow-up, FMA and MBI scores increased compared with those before treatment in the three groups（all<0.01）, with significant differences among the three groups (all<0.000 1) and better results in the ISA group compared with those in the other two groups (<0.05,<0.01) at the two time points. The FMA and MBI scores in the CSA group were higher than those in the rehabilitation group after treatment and at follow-up (all<0.05).

CONCLUSIONThe individualized scalp acupuncture can improve motor dysfunction and self-care ability of daily life for stroke patients.

OBJECTIVE：To optimi ze the ratio of four comp onents of Compound renshen jianti formulation （Panax ginseng ， Dioscorea oppositifolia ，Lycium barbarum fruit，Alpinia oxyphylla ），and to investigate its anti-fatigue activity and acute toxicity. METHODS：The water extract of Compound renshen jianti formulation was prepared by water extraction ，concentration and decompression drying. By single factor tests ，using weight-bearing swimming time as index ，the effects of four factors were investigated，such as the amount of P. ginseng ，D. oppositifolia ，L. barbarum fruit，A. oxyphylla . On the basis of single factor tests，using comprehensive score of weight-bearing swimming time ，serum urea nitrogen content ，liver glycogen content and AUC of blood lactate after exercise as index ，the formulation was optimized by Box-Behnken response surface method. The mice was divided into blank control group （water），positive control group （Renshen hongjingtian capsules ，0.135 g/kg）and compound low-dose，medium-dose and high-dose groups [the optimal ratio of Compound renshen jianti formulation extract （called“optimal compound formulation ”for short ）4.08，8.16，12.24 g/kg，by crude drug] ，intragastric administration of drug or distilled water 20 mL/kg，once a day ，for consecutive 30 d. The weight-bearing swimming time ，the contents of serum urea nitrogen ，liver glycogen and blood lactate AUC after exercise were used to optimize its anti-fatigue activity of optimal compound formulation. The comprehensive score was calculated based on the measured data of mice in the compound formulation middle-dose group ， and the difference between it and the theoretical prediction value was compared. The mice were given optimal compound formulation intragastrically （total dose 16.00 g/kg， by extract）. The general state ， body mass change ， toxic characteristics and death of mice were observed and recorded for 14 days. Median lethal dose （LD50）and maximum tolerated dose （MTD）were measured. RESULTS ：The optimal formulation ratio of Compound renshen jianti formulation included that P. ginseng 1.5 g，D. oppositifolia 10 g，L. barbarum fruit 10 g，A. oxyphylla 3 g. Results of anti-fatigue activity validation test showed that the optimal compound formulation could significantly prolonged weight-bearing swimming time ，reduced serum content of urea nitrogen ，blood lactate content and its AUC （except for low-dose group ），while significantly increased the content of liver glycogen （P＜0.05 or P＜0.01）. Average comprehensive score of medium-dose group was 96.95，which was only 0.06％ different from the theoretical prediction value of 97.01. The results of acute toxicity test showed that there was no death in mice. The oral MTD of the optimal compound formulation was more than 15 g/kg，which was non-toxic. CONCLUSIONS ：The optimal Compound renshen jianti formulation has effective anti-fatigue activity of mice ，and has no significant toxic effect.
