Efficacy of Chinese herbal medicine on nasal itching in children with allergic rhinitis: a systematic review and meta-analysis.

Background: Allergic rhinitis is prevalent among children and can cause nasal itching, fatigue, and even hinder growth and development. The main discomfort symptom of allergic rhinitis is nasal itching. Clinical reports suggest that Chinese herbal medicine (CHM) is effective in allergy rhinitis treatment. Therefore, we evaluate the clinical efficacy of Chinese herbal medicine in treating nasal itching caused by allergic rhinitis in children. Methods: Nine databases, including PubMed, Embase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wan Fang Data, CQVIP, Chinese Biological Medicine, and ClinicalTrials.gov, were systematically searched from their inception until March 2023. Randomized controlled trials (RCTs) comparing the efficacy of Chinese herbal medicine, either alone or in combination with Western medicine, to Western medicine treatment or placebo intervention for treating allergic rhinitis in children were eligible for inclusion. The effectiveness of Chinese herbal medicines for nasal itching was mainly evaluated. The Risk of Bias tool 2.0 assessed the risk of bias. Statistical analysis using RevMan 5.3 and Stata/SE 12. The quality of evidence was evaluated by GRADEpro 3.6. Risk ratios (RR) with corresponding 95% confidence intervals (CI) were utilized to evaluate and present dichotomous data, while mean difference (MD) and standardized mean difference (SMD) were employed for continuous data. A fixed-effects model was applied in cases where the data exhibited homogeneity (p > 0.1, I2 < 50%), whereas a random-effects model was utilized for heterogeneous data. Statistical significance was determined by a p-value <0.05. This study was conducted by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and its review protocol was registered on the International Platform for Registered Systematic Reviews and Meta-Analysis Programs (INPLASY202340076). Results: The review incorporated 23 studies. The meta-analysis indicated that herbal medicine was significantly related to the reduction of nasal itching (MD = -0.59, 95%CI: -0.94-0.24) and the increase of interleukin 10 level (SMD = 1.47, 95% CI: 0.90-2.05). Compared to Western medicine, the combining herbs and Western medicine showed better efficacy in relieving nasal itching, inhibiting immunoglobulin E, interleukin 4 and 33, enhancing interleukin 10, improving therapeutic efficiency, and reducing recurrent. Oral herbal medicine was more effective in treating nasal itching (MD = -0.45, 95% CI: -0.62-0.29). Combining oral and external herbal medicines was more efficient in treating nasal itching (MD = -0.44, 95% CI: -0.54-0.33), inhibiting immunoglobulin E, interleukin 4 (SMD = -0.87, 95% CI: -1.24-0.50) and 33 (SMD = -1.16, 95% CI: -1.54-0.77), and improving therapeutic efficiency. External herbal medicine did not show differences compared to Western medicines. Regarding safety, herbal medicine alone exhibited fewer adverse events than Western medicine; combining herbal and Western medicine showed no significant variation in adverse event incidence. Conclusion: Chinese herbal medicine (CHM) holds great potential in alleviating symptoms, modulating immune factors levels, and reducing relapse in pediatric rhinitis. Meanwhile, CHM is relatively safe. However, the efficacy and safety of CHM in treating pediatric rhinitis still need to be confirmed due to the inclusion of studies with low methodological quality, small sample sizes, and potential heterogeneity. More high-quality research is necessary to provide reliable evidence for the clinical application of CHM. Systematic Review Registration: INPLASY.com, identifier INPLASY202340076.

Real-world systemic sequential therapy with regorafenib for recurrent hepatocellular carcinoma: analysis of 93 cases from a single center.

BACKGROUND: Regorafenib is an oral multikinase inhibitor and became the first second-line systemic treatment for hepatocellular carcinoma (HCC) following the phase III RESORCE trial. This single-center study retrospectively analyzed the clinical data and follow-up results of patients with recurrent HCC treated with regorafenib and discussed the prognostic factors to provide guidance for clinical treatment. METHODS: Ninety-three recurrent HCC patients were enrolled in the research and follow up from December 2017 to December 2020. Clinical and pathological data were collected. SPSS software v26.0 was used (Chicago, IL, USA) for statistical analysis. A two-sided P < 0.05 was considered statistically significant. RESULTS: The patients included 81 males and 12 females with a median age of 57 years. Eighty-seven patients had hepatitis B virus (HBV) infection. The objective response rate (ORR) was 14.0%, and the disease control rate (DCR) was 62.4%. The median overall survival (mOS) and median time to progression (mTTP) were 15.9 and 5.0 months. Multivariate analysis showed that Child-Pugh classification, the Eastern Cooperative Oncology Group performance status (ECOG PS), the neutrophil-to-lymphocyte ratio (NLR), combined treatment, and the time from first diagnosis of HCC to second-line treatment were independent factors affecting the prognosis of recurrent HCC patients. CONCLUSIONS: This real-world study demonstrated similar findings to those of the RESORCE trial. Regorafenib could effectively improve the prognosis of patients after first-line treatment failure. Combination therapy under multidisciplinary treatment (MDT) team guidance could be effective in impeding tumor progression and improving the prognosis of recurrent HCC patients.

Children with type 1 diabetes in COVID-19 pandemic: Difficulties and solutions.

Children/adolescents with type 1 diabetes (T1D) require holistic approach and continuous care. However, the coronavirus disease 2019 (COVID-19) pandemic has made challenges for the T1D children and their caregivers, professionals, and the healthcare system. This minireview aims to consolidate and discuss the difficulties and solutions of children with type 1 diabetes in the COVID-19 pandemic. T1D has been the most common type of diabetes in children and adolescents and the last decades has seen a rapid increase in the prevalence of T1D in youths worldwide, which deserves a public concern particularly in the COVID-19 pandemic. As reported in previous studies, T1D is a risk factor related to severe cases, while the virus may induce new-onset diabetes and serious complications. Moreover, restriction strategies influence medical availability and lifestyle, impact glycemic control and compilation management, and thus pose stress on families and health providers of youths with T1D, especially on those with certain fragile conditions. Therefore, special treatment plans are required for children provided by caregivers and the local health system. Latest health tools such as improved medical devices and telemedicine service, as well as a combined support may benefit in this period. This minireview emphasises that continued medical access and support are required to prevent deteriorated condition of children and adolescents with diabetes throughout this pandemic. Therefore, strategies are supposed to be formulated to mitigate the difficulties and stress among this group, particularly in the most at-risk population. Proposed solutions in this minireview may help individuals and the health system to overcome these problems and help youths with T1D in better diabetes management during such emergency situations.

Systemic Therapy for Hepatocellular Carcinoma: Chinese Consensus-Based Interdisciplinary Expert Statements.

Background: Hepatocellular carcinoma (HCC) is the most common type of liver cancer and causes many cancer-related deaths worldwide; in China, it is the second most prevalent cause of cancer deaths. Most patients are diagnosed clinically with advanced stage disease. Summary: For more than a decade, sorafenib, a small-molecular-weight tyrosine kinase inhibitor (SMW-TKI) was the only molecular targeted drug available with a survival benefit for the treatment of advanced HCC. With the development of novel TKIs and immune checkpoint inhibitors for advanced HCC, the management of patients has been greatly improved. However, though angiogenic-based targeted therapy remains the backbone for the systemic treatment of HCC, to date, no Chinese guidelines for novel molecular targeted therapies to treat advanced HCC have been established. Our interdisciplinary panel on the treatment of advanced HCC comprising hepatologists, hepatobiliary surgeons, oncologists, radiologists, pathologists, orthopedic surgeons, traditional Chinese medicine physicians, and interventional radiologists has reviewed the literature in order to develop updated treatment regimens. Key Messages: Panel consensus statements for the appropriate use of new molecular -targeted drugs including doses, combination therapies, adverse reaction management as well as efficacy evaluation, and predictions for treatment of advanced HCC with evidence levels based on published data are presented, thereby providing an overview of molecular targeted therapies for healthcare professionals.

Efficacy and safety of Qinxiang Qingjie oral solution for the treatment of influenza in children: a randomized, double-blind, multicenter clinical trial.

Background: Qinxiang Qingjie (QXQJ), an oral solution containing various Chinese herbs, is indicated for pediatric upper respiratory tract infections. The treatment of influenza also shows potential advantages in shortening the duration of illness and improving symptoms. However, there is still a lack of high-quality clinical evidence to support this. The trial was to explore the efficacy and safety of QXQJ for treating pediatric influenza and provide an evidence-based basis for expanding its applicability. Methods: A randomized, double-blind, double-dummy, positive-controlled, multicenter clinical trial was conducted in 14 hospitals in China. Children aged 1-13 years with influenza and "exterior and interior heat syndromes" as defined by traditional Chinese medicine (TCM) were randomly assigned to two groups with 1:1 radio. Children in the test group received QXQJ oral solution and oseltamivir simulant, while the control group received oseltamivir phosphate granules and QXQJ simulant. The duration of treatment was five days, followed by a two-day follow-up period. The primary endpoint was the clinical recovery time. Secondary endpoints included the time to defervescence, incidences of complications and severe or critical influenza, negative conversion rate, improvement of TCM syndromes, and safety profiles of the therapeutics, which mainly contained the adverse clinical events and adverse drug reactions. Results: A total of 231 children were randomized to either the QXQJ (n=117) or oseltamivir (n=114) group. The FAS and PPS results showed that both groups experienced a median clinical recovery time of three days (P>0.05). The median time to defervescence of both groups were 36 hours in FAS and PPS (P>0.05), and two groups did not differ in terms of the other secondary endpoints (P>0.05). 14 patients (12.39%) in the QXQJ group and 14 patients (12.50%) in the oseltamivir group reported at least one adverse event, respectively. One serious adverse event occurred in the QXQJ group. There was no significant difference in the incidence of adverse events or adverse drug reactions between the groups. Conclusions: The efficacy of QXQJ oral solution was comparable to that of oseltamivir for treating influenza in children, with an acceptable safety profile.

Acupuncture for post-stroke cognitive impairment: a systematic review and meta-analysis.

OBJECTIVES: The aim of this study was to evaluate the effectiveness and safety of acupuncture for the treatment of post-stroke cognitive impairment (PSCI). METHODS: The Cochrane Library, Embase, Medline, China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Periodical (VIP), Wanfang, and Chinese Biological Medicine (CBM) databases were electronically searched from their inception to 10 April 2019. The Montreal Cognitive Assessment (MoCA) scale and Mini-Mental State Examination (MMSE) scale were used as outcomes to assess effectiveness with respect to cognitive function. Assessment of risk of bias (ROB) and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) assessment were performed by two reviewers independently. Data were analyzed using Review Manager (RevMan) 5.3. RESULTS: A total of 28 trials with 2144 participants were included in the qualitative synthesis and meta-analysis. Four of the 28 trials (14%) were assessed as being at overall low ROB, 24 of the 28 trials (86%) were assessed as having overall high ROB. The quality of evidence for both MoCA and MMSE were deemed to be very low by the GRADE criteria. Results indicated that acupuncture groups may be benefiting more than non-acupuncture groups with respect to variation of MoCA scores (merged mean difference (MMD): 2.66, 95% confidence interval (CI): 2.18 to 3.13, p < 0.00001; heterogeneity: χ2 = 35.52, p = 0.0007, I2 = 63%), and the heterogeneity decreased in both subgroup analysis and sensitivity analysis. In addition, acupuncture groups might be benefiting more than non-acupuncture groups in terms of changes in MMSE score (MMD = 2.97, 95% CI = 2.13 to 3.80, p < 0.00001; heterogeneity: χ2 = 269.75; p < 0.00001; I2 = 92%), and the heterogeneity decreased in subgroup analysis. Only one RCT addressed adverse events, and the symptoms were mild and did not affect treatment and evaluation. CONCLUSION: Acupuncture could be effective and safe for PSCI. Nevertheless, the results should be interpreted cautiously due to the high ROB of included trials and very low quality of evidence for assessed outcomes.

Clinical efficacy and safety of acupuncture treatment of TIC disorder in children: A systematic review and meta-analysis of 22 randomized controlled trials.

OBJECTIVE: To systematically evaluate the clinical efficacy and safety of acupuncture in the treatment of Tic Disorders (TD) in children, and to clarify the current evidence regarding the clinical application of acupuncture in the treatment of TD. METHODS: Randomized controlled trials (RCTs) comparing acupuncture treatment with pharmaceutical treatment for TD were included in this review. A comprehensive search of 6 electronic literature databases was conducted, and the retrieval date was from the establishment of the database to April 2020. The Cochrane Collaboration's bias risk assessment tool was used to evaluate the bias risk of the included literature, and adopted the Review Manager 5.3 was used for statistical analysis of the data in the included literature. RESULTS: A total of 22 RCTs (1668 participants) were included in this review. Meta-analysis indicated that acupuncture showed superior effects in the following aspects, including higher overall effective rate [RR = 1.20,95 % CI(1.09,1.20),P＜0.00001], significant reduction in Yale Global Tic Severity Scale (YGTSS) scores [MD=-2.79,95 %CI(-4.75,-0.82),P = 0.005], lower incidence of adverse effects [RR = 0.26,95 %CI(0.17,0.41),P＜0.00001], and reduced recurrence rate [RR = 0.28,95 %CI(0.17,0.46),P＜0.00001]. CONCLUSION: Acupuncture treatment alone is more effective in the treatment of TD than pharmaceutical treatment, as seen in the reduction of YGTSS scores, fewer adverse effects and lower recurrence rates.

Outcome of non-vitamin K oral anticoagulants in the treatment of left atrial/left atrial appendage thrombus in patients with nonvalvular atrial fibrillation.

BACKGROUND: Data comparing dabigatran with rivaroxaban regarding the resolution of left atrial/left atrial appendage (LA/LAA) thrombus in patients with nonvalvular atrial fibrillation (AF) are scarce. This study aimed to compare the efficacy and safety of dabigatran vs rivaroxaban regarding the resolution of LA/LAA thrombus in patients with nonvalvular AF. METHODS: This retrospective study enrolled nonvalvular AF patients scheduled to undergo catheter ablation or cardioversion in Shanghai Ruijin Hospital between January 2014 and January 2019. Altogether, 34 patients with LA/LAA thrombus detected by transesophageal echocardiography (TEE) were enrolled. Among them, 12 patients were treated with dabigatran 150 mg bid and the other 22 with rivaroxaban 20 mg qd. Follow-up TEE was performed within greater than or equal to 3 weeks to less than 6 months of the initial TEE to evaluate the resolution of the LA/LAA thrombus. RESULTS: Baseline patient characteristics were similar in the two groups. Overall, 18 patients (81.8%) in the rivaroxaban group had complete thrombus resolution after 70.3 ± 22.1 treatment days, and 10 patients (83.3%) in the dabigatran group had complete thrombus resolution after 69.3 ± 47.9 treatment days. There was no significant difference between the groups (P = .6). TEE showed that the average length, width, and area of thrombus significantly decreased in both groups after treatment, although there was no significant difference in the amount of change in these parameters between the two groups after treatment (P = .6). Undissolved thrombus in two patients in the rivaroxaban group did dissolve after switching to dabigatran. CONCLUSIONS: The results suggest that both dabigatran and rivaroxaban are potential options for treating LA/LAA thrombus in patients with nonvalvular AF. Dabigatran could be an alternative option for the resolution of LA/LAA thrombus resistant to rivaroxaban.

[Acupoint selection rules of acupuncture for cervical spondylotic radiculopathy based on data mining].

OBJECTIVE: To analyze the rules of acupoint selection in the acupuncture treatment of cervical spondylotic radiculopathy by data mining. METHODS: The randomized controlled trials (RCTs) regarding acupuncture for cervical spondylotic radiculopathy published from July 15 of 2009 to July 15 of 2019 were retrieved from databases of CNKI, VIP, Wanfang, SinoMed, PubMed and EMbase. A database was established with Microsoft Excel 2016. The frequency and total effective rate of high-frequency acupoints, meridians and acupoint combinations were analyzed, and the association rules of acupoints and meridians were analyzed by Apriori algorithm. RESULTS: A total of 87 RCTs were included, involving 104 acupoints with a total frequency of 921. Among them, the high-frequency acupoints were cervical Jiaji (EX-B 2, 87 times), Fengchi (GB 20, 70 times), Houxi (SI 3, 54 times), etc. The frequently-used acupoints were mainly distributed in the hand yangming large intestine meridian, the foot shaoyang gallbladder meridian and hand taiyang small intestine meridian. The frequently-used acupoint combination was Fengchi (GB 20)-cervical Jiaji (EX-B 2), and most of the combinations were acupoints at the proximal end and acupoints at the far and near end. With the analysis of association rules, 15 groups of acupoint association rules and meridian association rules were obtained. CONCLUSION: It is feasible to explore the acupoint selection and compatibility rules of acupuncture for cervical spondylotic radiculopathy by data mining. This study could provide corresponding reference for clinical treatment.

Changes in physicochemical properties of organic matter by uranium irradiation: A case study from the Ordos Basin in China.

Carbonaceous debris (CD) are exclusively disseminated in sandstones of uranium-bearing strata from the Dongsheng uranium ore field of the northern Ordos Basin, northern China. Physicochemical properties of CD were investigated through a series of tests including element analyses, Fourier transform infrared spectroscopy (i.e., FTIR) and organic carbon isotope (i.e., δC13) as well as specific surface area. The results show that δC13 of the samples from uranium-bearing strata range from -22.86‰ to -25.82‰, indicating that the CD is from the same origin. The average values of C, H, O and N are 54.54%, 4.55%, 39.15% and 0.49%, respectively, and H/C as well as O/C atomic ratios vary from 0.77 to 1.26 and 0.36 to 1.72, respectively, implying that CD is mostly composed of C and O, followed by H, and is grouped into Type Ⅲ kerogen at an immature to low mature stage. Compared with the samples without uranium enrichment, C, H, N and δ13C of the uranium-bearing samples increase by 13.66%, 5.32%, 12.50% and 0.98‰, respectively, while decrease by 18.50%, 7.84% and 33.33%, respectively, for O, H/C as well as O/C atomic ratios. As the intensity of uranium enrichment increases, H/C atomic ratios and aliphaticity decrease, and aromaticity increases. Besides, uranium-bearing samples are of smaller specific surface area than those without uranium enrichment. Alpha irradiation energy released by uranium and its daughters could cause the crosslinking in n-alkanes and long-chain polymers through a free-radical mechanism, which is supported by a decrease in O, aliphaticity and an increase in aromaticity. Hence, it results in polycondensation of molecular structure with a decrease in side chain length, function groups as well as specific surface area, and changes in physicochemical properties of organic matter, which is instructive in prospecting.

Role of acupuncture in the treatment of insulin resistance: A systematic review and meta-analysis.

BACKGROUND: and purpose Acupuncture has gained increasing attention in the treatment of insulin resistance (IR). This study systematically reviews the efficacy of acupuncture on clinical IR outcomes. METHODS: Cochrane Central Register of Controlled Trials, Embase, Medline (via OVID), China National Knowledge Infrastructure (CNKI), Wan Fang and China Science and Technology Journal Database (VIP) were searched to collect randomized controlled trials (RCTs) of patients with IR treated by acupuncture. Meta-analysis was performed by RevMan 5.3. RESULTS: With acupuncture, the homeostasis model assessment of insulin resistance (homa-IR) significantly decreased (mean difference (MD) = -1.04, 95% confidence interval (CI) -1.37 to -0.71; P < 0.00001), as did fasting blood glucose (FBG) (MD = -0.56, 95% CI -0.88 to -0.25; P = 0.0005), 2 h postprandial blood glucose (2hPG) (MD = -0.91, 95% CI -1.62 to -0.20; P = 0.01), and fasting insulin (FINS) (MD = -3.23, 95% CI -4.14 to -2; P < 0.00001). Meanwhile, the insulin sensitivity index (ISI) (MD = 0.36, 95% CI 0.18 to 0.53; P < 0.0001) increased, and fewer adverse events occurred. CONCLUSION: Acupuncture may improve homa-IR, ISI, FBG, 2hPG and FINS with fewer adverse events than other treatments, making it a viable treatment for IR.

F-box protein-32 down-regulates small-conductance calcium-activated potassium channel 2 in diabetic mouse atria.

Diabetes mellitus (DM) is an independent risk factor for atrial fibrillation, but the underlying ionic mechanism for this association remains unclear. We recently reported that expression of the small-conductance calcium-activated potassium channel 2 (SK2, encoded by KCCN2) in atria from diabetic mice is significantly down-regulated, resulting in reduced SK currents in atrial myocytes from these mice. We also reported that the level of SK2 mRNA expression is not reduced in DM atria but that the ubiquitin-proteasome system (UPS), a major mechanism of intracellular protein degradation, is activated in vascular smooth muscle cells in DM. This suggests a possible role of the UPS in reduced SK currents. To test this possibility, we examined the role of the UPS in atrial SK2 down-regulation in DM. We found that a muscle-specific E3 ligase, F-box protein 32 (FBXO-32, also called atrogin-1), was significantly up-regulated in diabetic mouse atria. Enhanced FBXO-32 expression in atrial cells significantly reduced SK2 protein expression, and siRNA-mediated FBXO-32 knockdown increased SK2 protein expression. Furthermore, co-transfection of SK2 with FBXO-32 complementary DNA in HEK293 cells significantly reduced SK2 expression, whereas co-transfection with atrogin-1ΔF complementary DNA (a nonfunctional FBXO-32 variant in which the F-box domain is deleted) did not have any effects on SK2. These results indicate that FBXO-32 contributes to SK2 down-regulation and that the F-box domain is essential for FBXO-32 function. In conclusion, DM-induced SK2 channel down-regulation appears to be due to an FBXO-32-dependent increase in UPS-mediated SK2 protein degradation.

Exploring association between gastrointestinal heat retention syndrome and recurrent respiratory tract infections in children: a prospective cohort study.

BACKGROUND: Recurrent respiratory tract infections (RRTIs) have a negative impact on both children's health and family wellbeing. Deficiency of ZhengQi used to be an instinct factor driving RRTI in Traditional Chinese Medicine (TCM). Our clinical observations suggest that children with gastrointestinal heat retention syndrome (GHRS) may have a greater risk of catching respiratory tract infections (RTIs). GHRS is a new predisposing factor for RRTI and it is dietary related. This study is aimed to explore association between GHRS and RRTI. METHODS: A prospective cohort study has been conducted in Beijing, China; children aged 1-18 were enrolled. TCM symptoms, demographic and physiological characteristics were recorded by using semi-structured questionnaire. GHRS was considered as a predisposing factor. Children were followed up for next 12 months. We contacted with their parents using a face-to-face questionnaire survey, via email or phone every 3 months. Episodes of RTIs were recorded in detail. RESULTS: Three hundred thirty four children were enrolled and 307 (91.92%) followed up for 12 months. The incidence of RTI was 4.32 episodes per child-year (95 % CI 4.03-4.61). 69 (43.13%) children in the group with GHRS suffered from RRTI; there were 48 (32.65%) children in group without GHRS. The risk ratio (RR) value of RRTI occurrence was 1.32 (95 % CI 0.91-1.91, P = 0.139), and the attributable risk percent (AR%) was 24.28%. Dry stool and irritability were positively correlated with RTI episodes, age and BMI were negatively correlated with RTI episodes in a linear regression model. Dry stool (OR = 1.510) was positively correlated with RRTI occurrence, age (OR = 0.889) and BMI (OR = 0.858) were negatively correlated with RRTI occurrence in our logistic regression model. CONCLUSIONS: GHRS is associated with RRTI in this cohort. Dry stool was positively associated with RRTI, and BMI was negatively associated with RRTI. Studies with larger sample size and longer follow up are needed to further evaluate this association. Relieving GHRS should be considered when TCM practitioners treat RRTI children, and this may protect children from suffering RTIs. TRIAL REGISTRATION: Chinese Clinical Trial Registry Number: ChiCTR-CCH-13003756.

Experimental study on the effect of Kang-Lai-Te induced apoptosis of human hepatoma carcinoma cell HepG2.

BACKGROUND: Kang-Lai-Te (KLT) is extracted from the traditional Chinese herbal medicine Semen Coicis, which has been used in China as an effective clinical drug for over a thousand years. It contains numerous ingredients with anti-tumor effects. In our previous studies on transplanted hepatomas in rats, KLT could stop the cells in the G2+M stage of cell cycle and then reduce the number of cells entering the stage G0 and G1, but the mechanism of the anti-proliferative effect was unknown. In this experiment, we examined whether KLT inhibits HepG2 cell growth, if so, tried to explore its mechanism. METHODS: KLT at different concentrations was used for the treatment of hepatocellular carcinoma cells in vitro, respectively. The proliferation inhibitory rate was evaluated by MTT assay, induction of cell apoptosis rate and the protein levels of Fas and Fas ligand (FasL) were determined by flow cytometry (FCM), and the expression of Fas and FasL mRNA was detected by real-time fluorescent quantitative RT-PCR. RESULTS: KLT produced an obvious time and dose-dependent inhibitory effect on HepG2 cells, and marked apoptosis was detected by FCM. The protein of Fas increased by 11.01%, 18.71%, 28.71% and 37.15%; the protein of FasL increased by 1.49%, 1.91%, 3.27% and 3.38% in comparison with the control (P<0.05). Real-time fluorescent quantitative RT-PCR showed that treating HepG2 cells with KLT caused the upregulation of Fas and FasL mRNA. CONCLUSION: KLT inhibits HepG2 growth by inducing apoptosis, which may be mediated through activation of the Fas/FasL pathway.

[Clinical characteristics of 7 patients with gestational diabetes insipidus].

OBJECTIVE: To investigate the clinical feature, treatment and prognosis of both the mother and the fetus with gestational diabetes insipidus. METHODS: A total of 7 cases of gestational diabetes insipidus collected in the First Affiliated Hospital of Wenzhou Medical College, Wenzhou Combination of Traditional Chinese Medicine with Western Medicine Hospital, and Zhejiang Taizhou Hospital from June 1993 to June 2006 were analyzed retrospectively. RESULTS: Seven cases symptoms all characterized by excessive thirst polydipsia and polyuria. The average 24 h urinary output was between 11 L to 13 L and manifested of hypobaricuria. After effective treatment (three cases were treated with 1-deamino-8-D-arginine vasopressin, another three patients were managed with hydrochlorothiazide, and the last one was cured with antisterone), seven patients with gestational diabetes insipidus did not have any severe consequences. Their symptoms of excessive thirst, polyuria, and polydypsia disappeared from 7 days to 3 months after parturition. Urinary volume returned to normal standard of 1000-2000 ml during 24 hours. Specific gravity of urine recovered normally between a range 1.015-1.025 and serum sodium recovered between 135-147 mmol/L. The average duration of illness was 52 days. Eight newborn infants survived. Two of them were sent to neonatal intensive care unit for treatment. One was because of premature delivery caused by antepartum eclampsia, and the other case was one of the twins who had hydronephrosis. The baby of the first case left hospital after 3 weeks' treatment. The latter one's symptom disappeared 2 weeks after delivery. No obvious symptom was discovered among all the babies through follow-up telephone calls 42 days after childbirth. CONCLUSION: Gestational diabetes insipidus is a rare endocrinopathy complicating pregnancy. This disorder is characterized by excessive thirst, polydypsia, polyuria, hypobaric urine and electrolyte disturbances usually manifesting in the third trimester of pregnancy or puerperium. This is a transient syndrome. The first treatment of choice in patients with gestational diabetes insipidus is 1-deamino-8-D-arginine vasopressin and the second-choice is hydrochlorothiazide. Early diagnosis and appropriate management of the disease may reduce the hazard for both the mother and the fetus during perinatal period.

Efficacy of intra-tumor injection of Kang-Lai-Te in treating transplanted hepatoma in rats.

BACKGROUND: Non-operative therapy takes an important position in comprehensive therapy of liver cancer. Despite some effects by using ethanol, acetic acid and heat saline for intra-tumor injection in the treatment of liver cancer, it is difficult to attain a complete cure but bring about injury to the liver to some extent. Hence, searching for other drugs for the local treatment of liver tumor is an important option. This study was designed to set up rat models of transplanted liver cancer, intra-tumor injection of Kang-Lai-Te (KLT), and negative control (saline) and positive control (ethanol). The effect of intra-tumor injection of KLT in treating transplanted hepatoma in rats and its advantages and disadvantages were assessed and the possibility of its use in treating patients with liver cancer was evaluated. METHODS: Forty rats were divided into 4 groups (G1, G2, G3 and G4, 10 rats in each group). Different drugs were injected into their implanted hepatoma (G1 with 0.2 ml saline as control, G2 with 10 mg KLT, G3 with 20 mg KLT, G4 with 0.2 ml ethanol). After 3 and 8 days, the hepatoma volume (HV), the serum levels of albumin, alanine aminotransferase(ALT), aspartate aminotransferase alkaline phosphatase(ALP) and creatinine, as well as the expression of proliferation cell nuclear antigen(PCNA) in hepatoma were detected. RESULTS: After 3 days, the HVs were smaller in G3 and G4 than in G1 (P<0.05), the serum levels of albumin were higher in G2 and G3 than in G1 and G4 (P<0.05), the serum levels of ALT and AST were lower in G2 and G3 than in G4 (P<0.05), the serum levels of ALP was lower in G2 and G3 than in G1 and G4 (P<0.05),the PCNA labeling indexes (PCNA LI) were lower in G2 and G3 than in G1 and G4 (P<0.05). After 8 days, the HVs were smaller in G2, G3 and G4 than in G1 (P<0.05), and the differences of HVs among G2, G3 and G4 were not significant. The serum levels of ALP were lower in G1, G2 and G3 than in G4 (P<0.05), and the PCNA LI were lower in G3 than in G1 and G4 (P<0.05). CONCLUSION: Intra-tumor injection of KLT into implanted hepatoma is evidently effective, but it is less effective than ethanol. The effect of KLT on liver function is markedly lower than that of ethanol.

Efficacy of intra-tumor injection of Xiao-Zhi-Ling on transplanted hepatoma in rats.

AIM: To study the therapeutic effectiveness of intra-tumor injection of Xiao-Zhi-Ling(XZL) on transplanted hepatoma in rats. METHODS: Sixty rats were divided into 3 groups (groups S, X and E), 20 in each. Different drugs were injected into the implanted hepatoma (Group S with 0.2 ml saline as control, group X with 0.2 ml XZL, group E with 0.2 ml ethanol). After 3 days and 8 days respectively, we detected the hepatoma volume (HV), the level of albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in serum, and the expression of proliferating cell nuclear antigen (PCNA) in hepatoma. RESULTS: The results were obtained after 3 days, the HVs in groups X and E were smaller than those in group S (group X vs S P=0.010(*), group E vs S P=0.002(*), P<0.05). The levels of ALT and AST in group S and X were lower than those in group E (ALT Group S vs E P=0.019(*), group X vs E P=0.003(*), P<0.05; AST group X vs E P=0.002(*), P<0.05). The levels of ALP and PCNA labeling index in group X were lower than those in group S and E (ALP group X vs S P=0.000(*), group X vs E P=0.000(*). P<0.05; PCNA group X vs S P=0.008(*), group X vs E P=0.048(*), P<0.05). The levels of creatinine in group S were lower than those in group E (group S vs E P=0.017, P<0.05). The degree of tumor necrosis in group S was lower than those in groups X and E (group S vs X P=0.006(*), group S vs E P=0.006(*), P<0.05). After 8 days, the HVs in groups X and E were smaller than those in group S (group X vs S P=0.007(*), group E vs S P=0.004(*), P<0.05). The difference of HVs between groups X and E was not significant. The levels of albumin, ALT, AST and creatinine in group X were not higher than those in other groups, the levels of ALP and PCNA in group X were lower than those in groups S and E (ALP group X vs E P=0.006(*) P<0.05; PCNA group X vs S P=0.044(*), group X vs E P=0.021(*), P<0.05). The degree of tumor necrosis in group S was lower than that in groups X and E (group S vs X P=0.001(*), group S vs E P=0.002(*), P<0.05). CONCLUSION: The therapeutic effectiveness of intra-tumor injection of XZL and ethanol on implanted hepatoma is obvious, but the toxicity of XZL on liver function is markedly lower than that of group E, at the same time XZL can inhibit the growth of tumor. XZL is relatively better and safer than ethanol in intra-tumor injection therapy.
