OBJECTIVETo observe the clinical efficacy and safety of Tiaozhi Yanggan Decoction (TZYGD) in treating non-alcoholic fatty liver.
METHODSOne hundred and thirty-eight patients were enrolled and randomized into two groups according to the random number table in a ratio of 3:1, with 8 cases eventually dropping out. The symptoms, signs, liver function markers, blood lipids, iconographic indices and clinical comprehensive efficacy after a 12-week treatment course were assessed in 101 patients treated with TZYGD in the treated group and 29 patients treated with Thiola in the control group.
RESULTSThe total effective rate in the treated group and the control group was 81.19% and 68.97%, respectively, showing a significant difference between the two groups with the former being significantly higher than the latter (P<0.05). Moreover, the improvements in the symptoms, signs, liver function, blood lipids and iconographic indices in the treated group were favorable with no serious adverse reactions.
CONCLUSIONTZYGD is effective and highly safe in treating non-alcoholic fatty liver.

OBJECTIVETo investigate the changes of serum reproductive hormones with male aging and to compare the differences in the hormone levels among different age groups or between township and rural males of the same age group.
METHODSUsing cluster and stratified sampling, we recruited 434 healthy old and middle-aged (40-69 years) males, 198 from the township and 236 from the rural communities. We determined the concentrations of serum total testosterone (tT), luteinizing hormone (LH) and sex hormone binding globulin (SHBG), free testosterone (fT), bio-available testosterone (Bio-T), and obtained the testosterone secretion index (TSI) and free testosterone index (fTI). Meanwhile, we included fifty-nine 20-39 years old males from the same communities in a control group.
RESULTSWith the increase of age, the serum tT levels did not change significantly, while the levels of serum LH and SHBG increased, and those of fT, Bio-T, TSI and fTI decreased gradually. Statistically significant differences were found among the four different age groups in all the parameters of reproductive hormones (P < 0.01), except in the serum tT level (P > 0.05). The serum tT level was not significantly correlated with aging and LH (P > 0.05). Serum LH and SHBG had a marked positive correlation with aging, and SHBG with LH (P < 0.01), while fT, Bio-T, TSI and fTI were negatively correlated with aging and the LH level (P < 0.01). Serum LH, TSI and fTI showed statistical differences (P < 0.05), while fT and Bio-T exhibited extremely significant differences (P < 0.01) between the township and rural males in the 40 -49 yr group, and in the same age group, the increase rates of serum LH and SHBG and reduction rates of fT, Bio-T, TSI and fTI were higher in the rural men than in the township residents. However, the results were just the opposite in the 50 - 59 and 60 - 69 yr groups.
CONCLUSIONThe levels of serum LH, SHBG, fT, Bio-T, TSI and fTI changed with aging in a gradientmanner in the old and middle-aged males, but no significant changes were observed in the level of serum tT. There were statistical differences in many parameters of serum reproductive hormones among different age groups or between township and rural males.

To study the program of evaluating mothers and infants after 6 months of cord blood donation, from June 1998 to February 2004, all mothers after 6 months of cord blood donation were followed-up by phone calls or letters to report on the health condition. The results showed that when 3 195 mothers were visited by phone calls, 18 mothers declined to answer. 392 letter were send to those who could not be found by phone, 15 of whom wrote back. The average time to talk with each mother was approximately 12 minutes. Follow-up on the baby donors showed two cases with chromosome abnormality, one with hypothyroidism, one with neutropenia, one with albinism and 5 dead with unclear reasons. The cord blood components from all these abnormal donors found were discarded. In conclusion, the programs to evaluate mother and baby after 6 months of cord blood donation seems important in quality control of the components stored in cord blood bank.

OBJECTIVETo compare the detection rates of Mycoplasma pneumoniae (MP) from nasopharyngeal aspirates (NPA) and bronchoalveolar lavage fluid (BALF) in children with pneumonia.
METHODSA total of 164 hospitalized children with pneumonia were enrolled. NPA and BALF of these children were collected within 24 hours of admission, and MP-DNA was detected by fluorescence quantitative PCR. Venous blood samples of all these children were collected within 24 hours of admission and on days 7-10 of treatment, and serum MP-IgM was detected using ELISA.
RESULTSThe positive rate of MP-DNA in NAP of the 164 cases was 51.8% , which was lower than 63.4% as the detection rate of MP-IgM in serum (P=0.044), and the two detection rates were moderately consistent with each other (Kappa=0.618, P<0.01). The positive rate of MP in BALF was 71.3%, which was not significantly different with that of MP-IgM in serum (P>0.05), and the detection rates were well consistent (Kappa=0.793, P<0.01). The detection rate of MP in NPA was lower than that in BALF (P<0.01), with moderate consistency between two of them (Kappa=0.529, P<0.01). The median MP copy number in BALF was significantly higher than that in NPA (P<0.01). The MP detection rates in NPA and BALF were significantly different among different courses of disease (P<0.05). As the course of disease extended, the MP detection rates in both NPA and BALF showed a declining trend; children with MP pneumonia of 1-2 weeks' duration and 2-4 weeks' duration had a higher MP-DNA detection rate in BALF than in NPA (P<0.05).
CONCLUSIONSMP-DNA in BALF has a high sensitivity, with a great significance for early diagnosis of MP pneumonia, while NPA MP-DNA tests may lead to a missed diagnosis.

OBJECTIVE:
To observe the length heteroplasmy and point heteroplasmy in human mtDNA control region.
METHODS:
The peripheral blood, buccal cell, and single hair shaft from 50 individuals and 16 family members, related in their maternallineage were analyzed by direct sequencing, and clones from 20 individuals whose mtDNA sequences have a T-C transition at 16189 nt were sequenced.
RESULTS:
No point heteroplasmy were observed in peripheral blood, buccal cell, single hair shaft from the same individual, neither in maternally related individuals. Length heteroplasmy was observed in those individuals with a homopolymeric tract and the different clones from the same individual has different proportions of length variants, but the hair shafts from the same individual were very similar to the measurements made from blood DNA. No length heteroplasmy was observed between different tissues from the same individual.
CONCLUSION
mtDNA sequences have a characteristic of high consistency and genetic stability, mtDNA sequencing is a suitable tool for forensic applications such as individual identification.

In order to study the feasibility of multi-umbilical cord blood transplantation (multi-UCBT) in adult, 13 cases of unrelated allogeneic multi-UCBT performed from June 1998 to July 2003 were analyzed retrospectively. All cord blood units were obtained from full term normal vaginal and cesarean deliveries in Guangzhou Maternity and Neonatal Hospital. The fractionation, cryopreservation and thawing of cord blood were done according to the regulation of New York Umbilical Cord Blood Bank and pertinent literatures. Donors of HLA 1/6-2/6 mismatch were accepted at registry search. The results showed that from June 1998 to July 2003, 28 umbilical cord blood units were selected by 7 transplantation centers for 13 cases. The median age of recipients was 22 (8 - 41) years, and the median weight was 50 (21 - 75) kg, the median infused dose of total nuclear cells was 2.91 x 10(7)/kg. Six out of thirteen cases were engrafted after cord blood infusion with absolute neutrophil count of > 5.0 x 10(8)/L at 19 days post-infusion. Only one case suffered from graft versus host disease, the total survival of multi-UCBT was 46.2% (6/13). It is concluded that good prospects in the field of multi-umbilical cord blood transplantation is likely to be realized.

In order to research the related factors of umbilical cord blood transplantation, 54 cases of unrelated umbilical cord blood transplantation were analyzed retrospectively, which were performed from June 1998 to July 2003. All cord blood units were obtained from full term normal vaginal deliveries in Guangzhou Maternal-Neonatal Hospital. The fractionation, cryopreservation and thawing of cord blood have been done according to the regulation of New York umbilical cord blood bank and pertinent literature. The selection of cord blood is based on HLA typing and the number of nucleated cells. The results showed that from June 1998 to July 2003, 3 475 units of cord blood were collected in Guangzhou Umbilical Cord Blood Bank and 99 units were provided for therapy of 85 patients in 21 transplantation centers, including 11 sibling and 74 unrelated cord blood transplantations. 54 cases of unrelated cord blood transplantation were reported, including 43 malignant diseases and 11 non-malignant diseases. The median age of recipients was 9.5 (range 1.2 - 33) years, the median weight was 27 (range 10 - 60) kg, the median number of TNC was 6.82 x 10(7)/kg, 43 cord blood were implanted (ANC > 500/microl) at day 60 after transplantation (79.6%, median 17). The time of nuclear cell reconstitution after cord blood transplantation was statistically related with nucleated cells and the type of disease, not related with HLA matching. Acute GVHD was present in 8 patients (21.6%) and chronic GVHD occurred in 2 patients (5.4%), 6 patients suffered from graft failure (11.1%). The total survival rate was 42.6%. It is suggested that unrelated umbilical cord blood transplantation seems to be a good substitute for bone marrow transplantation and has good prospects especially in children.

OBJECTIVES:
To evaluate myocardial injury in neonates born to pregnant women with pregnancy complicated by severe preeclampsia by myocardial work indices.
METHODS:
A prospective cohort study was performed on 25 preterm infants born to the pregnant women with severe preeclampsia from June 2020 to April 2021 (severe preeclampsia group), and 25 preterm infants born to the pregnant women without severe complications in pregnancy were enrolled as the control group. Echocardiography was performed within 24 hours and at 48-72 hours and 14-28 days after birth to measure conventional parameters. Two-dimensional speckle-tracking echocardiography was performed to construct a noninvasive left ventricular pressure-strain loop based on two-dimensional myocardial strain and left ventricular systolic pressure noninvasively measured, so as to calculate myocardial work indices.
RESULTS:
Compared with the control group, the severe preeclampsia group had significant reductions in left ventricular global work index and global constructive work within 24 hours after birth (P<0.05), a significant reduction in left ventricular global work efficiency and a significant increase in global waste work at 48-72 hours after birth (P<0.05), and a significant reduction in left ventricular global work efficiency at 14-28 days after birth (P<0.05).
CONCLUSIONS
Subclinical myocardial injury persists in the neonatal period in preterm infants born to pregnant women with severe preeclampsia.
